Once the Barium Defendants have access to a victim computer through the malware described above , they monitor the victim 's activity and ultimately search for and steal sensitive documents ( for example , exfiltration of intellectual property regarding technology has been seen ) , and personal information fi"om the victim 's network . Sending the help command for each , you can see the extra features added between version 3.1 and 3.2 . The “ ExecStart ” value specifies the path of the program to be run , which in this case was GOGETTER .


If the malware determines that is not running on an emulator , it then performs additional checks to ensure that it wo n't be detected . We observed Moafee running HTRAN proxies on their multiple Command and Control ( C2 ) servers – all operated on CHINANET , and hosted in Guangdong Province . ShadowHammer : HEUR : Trojan.Win32.ShadowHammer.gen . The first step is the previously unknown OWA exploit technique .


We believe that the Carbanak campaign is a clear indicator of a new era in cybercrime in which criminals use APT techniques directly against the financial industry instead of through its customers . specifically CVE-2018-0798 , before downloading subsequent payloads .


This recurring , blindingly-fast Sofacy attack attracted our attention as neither sample was delivered through a zero-day vulnerability — instead , they appeared to be downloaded and installed by another malware .


On installation , the app requests the user to provide SMS storage access and high Android privileges such as Device Admin . Shrouded Crossbow targeted privatized agencies and government contractors as well as enterprises in the consumer electronics , computer , healthcare , and financial industries . So much so that Microsoft did a takedown in 2012 . It is therefore recommended to set the code only as a response for or methods and to use instead , as the method change is explicitly prohibited in that case .


After installation , the malware connects to the designated Command and Control ( C & C ) server , and receives a command to perform . Carbanak is a remote backdoor ( initially based on Carberp ) , designed for espionage , data exfiltration and to provide remote access to infected machines . On April 22 , 2015 , Suckfly exploited a vulnerability on the targeted employee 's operating system ( Windows ) that allowed the attackers to bypass the User Account Control and install the Nidiran back door to provide access for their attack .


Potentially malicious iOS connection Using the codes and “ Concipit1248 ” to check for more versions , we found two other apps in the App Store . It is highly likely that this threat is far more widespread and we urge financial institutions around the world to scan their networks for signs of the Metel malware . the following microcode graph shows edi is assigned to esi ( the block comparison variable in this case ) Rhysida appears to have first popped up back in May , with several high - profile compromises posted on their leak site .


The packet is serialized into a stream of bytes .


When analyzing the Ginp ’ s recent samples , ThreatFabric analysts found some similarities with the famous Android banking Trojan . The configuration file then loads the Trochilus payload into memory by injecting it into a valid system process . It turned out that the DLL files we found are a custom variant of Gh0st RAT , and the EXE files download the RAT .


The certificates are only as secure as the safeguards that organizations put around them .


Once installed , the application requests permissions so that it may control SMS messages and steal sensitive data on the device , as well as proliferate to other devices in the target device ’ s contact list . These RAT families are discussed in Novetta’s other report on the Lazarus Group’s RAT and Staging capabilities . The fact that Gallmaker appears to rely exclusively on LotL tactics and publicly available hack tools makes its activities extremely hard to detect .


( It is specified in the interception template whether a reply must be sent , and which text should be sent to which address . The vulnerability exists in the old Equation Editor ( EQNEDT32.EXE ) , a component of Microsoft Office that is used to insert and evaluate mathematical formulas . In November 2017 , CTU researchers discovered the North Korean cyber threat group , known as Lazarus Group , had launched a malicious spearphishing campaign using the lure of a job opening for the CFO role at a European-based cryptocurrency company .


Four files tested in 2014 are based on the open-source project , cryptcat .


Release_Time : 2015-05-28


Apps that have this permission can draw a window that belongs to the system group and can ’ t be dismissed . Beginning in early March 2018 , Unit 42 started observing Gorgon group attacks against Russian , Spanish and United States government agencies operating in Pakistan . Additionally there is a known issue with the result ( e.g , the remaining loop or paradoxical decompiled code ) With regards to these similarities , we highlight the following trends which could manifest in future OT malware : •


We have also found a Russian-language error message in many PinchDuke samples which translates as , “ There is an error in the module ’s name ! The length of the data section name must be 4 bytes! ” Additionally , Kaspersky noted that based on the compilation timestamps , the authors of the Duke malware appear to primarily work from Monday to Friday between the times of 6am and 4pm UTC+0 .


Beginning within the data field , all contents of the FLV stream become 0xEE .


To deliver the malware to the victim machines , the Rocke group exploits vulnerabilities in Apache Struts 2 , Oracle WebLogic , and Adobe ColdFusion . While the group used watering hole attacks in 2013 , it's still unclear how victims get redirected to the exploitation kits in the new 2014-2015 attacks .


At this stage , half the job is done for the malware . McAfee Advanced Threat Research team 's analysis , we find multiple components from this operation are unique from a code perspective , even though the code is loosely based on previous versions of the SYSCON backdoor . , It allows security researchers to analyze the source code and understand the attacker ’s tactics , techniques and procedures ( TTPs ) , which helps security professionals develop effective detection rules and enhance security products ' capabilities in combating ransomware threats .


This organization was formerly known as the East Turkestan Islamic Party and is purported to be an Islamic extremist separatist organization founded by Uyghur jihadists . Learning to access video game production environments enabled APT41 to develop the tactics , techniques , and procedures (TTPs) that were later leveraged against software companies to inject malicious code into software updates . We identified three themes in APT28 's lures and registered domains , which together are particularly relevant to the Russian government .


The malicious documents that Unit 42 examined contained legitimate decoy lures as well as malicious embedded EPS files targeting the CVE-2015-2545 and CVE-2017-0261 vulnerabilities . The Leafminer operators use EternalBlue to attempt lateral movement within target networks from compromised staging servers .


OurMine is well known : They hijacked WikiLeaks' DNS last month shortly after they took over HBO 's Twitter account ; last year , they took over Mark Zuckerberg 's Twitter and Pinterest accounts ; and they hit both BuzzFeed and TechCrunch not long after that . The infection vector is a spear-phishing email with a malicious attachment .


Based on observations associated with the malicious document , we observed subsequent shell sessions probably associated with Metasploit B-MAL S-TOOL ’s Meterpreter that enabled deployment of additional tools and malware preceding deployment of three Shamoon-related files : ntertmgr32.exe , ntertmgr64.exe and vdsk911.sys .


Even now , this is still not enough . After the source codes of their tools became public in 2016 , the name Buhtrap was used for the financial Trojan . The unzIP . Both of these campaigns use a similar structure with compromised WordPress sites hosting the lure shortcuts and a WebDav server that loads NetSupport RAT .


We are however only aware of one instance - the exploitation of CVE-2013-0640 to deploy MiniDuke - where we believe the exploited vulnerability was a zero-day at the time that the group acquired the exploit .


Malware data leak When we analyzed the sample , we realized that the malware operators left the remote database with some of the victims ’ data freely accessible , without any authentication . The comparison of the infection chains reveals in both cases TA505 used a couple of SFX stages to deploy the RMS” software: a legitimate remote administration tool produced by the Russian company TektonIT . When victims open malicious documents attached to the emails , the malware scans for Bitcoin activity and then establishes an implant for long-term data-gathering .


Once the HenBox app is installed and launched , it launches an install process for the embedded app as a decoy to other malicious behaviors occurring in the background , and to satisfy the victim with the app they were requesting , assuming they requested to download a particular app , such as DroidVPN . By 2014 , the Winnti malware code was no longer limited to game manufacturers . Between November 26 , 2015 , and December 1 , 2015 , known and suspected China-based APT16 launched several spear phishing attacks targeting Japan and Taiwan in the high-tech , government services , media and financial services industries .


After that , it carries out the malware operator ’s commands in order to install the next stage permanent payload .


Some of the documents exploited CVE-2017-0199 to deliver the payload . Threat actors may use the date string hardcoded into each Bookworm sample as a build identifier .


The Magic Hound attacks did not rely on exploit code to compromise targeted systems , instead relying on Excel and Word documents containing malicious macros . We successfully unpacked the initial sample we found dropped by the UPX unpacker .


The only active target list observed in the wild is available in the appendix and contains a total of 30 unique targets . The hacking activities of SectorJ04 group , which targeted South Korea in the first half of 2019 , have been continuously discovered . BRONZE BUTLER has demonstrated the ability to identify a significant zero-day vulnerability within a popular Japanese corporate tool and then use scan-and-exploit techniques to indiscriminately compromise Japanese Internet-facing enterprise systems .


delivery : to deliver specified text to all victim ’ s contacts ( SMS worming ) . We assess this activity was carried out by a suspected Iranian cyber espionage threat group , whom we refer to as APT34 , using a custom PowerShell backdoor to achieve its objectives . This particular RAT attempts to target a very specific set of Arabic-speaking countries . Change it Up in 2023 Get Ahead of Known Vulnerabilities


The other is a custom utility which , despite its large size , has limited functionality and acts as a tunnel , possibly used by the attackers to maintain persistence within the compromised network .


Unit 42 and others have shown in the first half of 2018 how this threat actor group continues to target multiple organizations throughout the world with a strong emphasis on government , diplomatic and other strategic organizations primarily in North America and Europe .


Handover from initial module to the main payload As mentioned , the initial handover component called triggerInfection with an instance of appObj and a method that returns the value for the variable config . Other names for the group are Vixen Panda , Ke3chang , Royal APT , and Playful Dragon . Among these 5 tools, only WinZip and Windows’ unzIP S-TOOL were not able to extract anything from the ZIP file as they encountered an error at the start of the extraction . The hacking and defacement of a U.S. Government system in which the attackers post messages disparaging remarks about capitalism or democracy would be a solid example of hacktivism .


The Trick , also known as Trickbot , is another banking Trojan that TA505 first began distributing in June of 2017 , although we have observed The Trick in the wild since fall 2016 , usually in regionally targeted campaigns .


It mainly targets Chinese users , but has also successfully affected people and organizations in the United States , United Kingdom , Thailand , Spain , and Ireland . The detection evasion techniques we observed in the Okrum malware include embedding the malicious payload within a legitimate PNG image , employing several anti-emulation and anti-sandbox tricks , as well as making frequent changes in implementation . Some organizations use the name Lazarus Group to refer to any activity attributed to North Korea .


backdoor , Sednit , Seduploader , JHUHUGIT , Sofacy .


This trend continued until late September 2017 , when we saw Magnitude EK focus primarily on the APAC region , with a large chunk targeting South Korea . Other groups attributed to Iranian attackers , such as Rocket Kitten , have targeted Iranian individuals in the past , including anonymous proxy users , researchers , journalists , and dissidents .


With our interest piqued , we pivoted on the import hashes ( also known as an imphash ) , which captures the import table of a given file .


Attempts to sign malware with code-signing certificates have become more common as the Internet and security systems have moved towards a more trust and reputation oriented model .


There was no open-source footprint for the remaining 42 addresses , suggesting that TG-4127 acquired them from another source , possibly other intelligence activity .


Read more about Dragos ’ approach to categorizing threat activity and attribution .


Svpeng In mid-July , we detected Trojan-SMS.AndroidOS.Svpeng.a which , unlike its SMS Trojan counterparts , is focused on stealing money from the victiim ’ s bank account rather than from his mobile phone . This matches with known Tactics , Techniques , and Procedures ( TTPs ) for Tropic Trooper , targeting both government institutions and also the energy industry in Taiwan . The Winnti Group is still actively using one of its flagship backdoors , ShadowPad , this time against Hong Kong universities . None The discovery was part of recent CrowdStrike Services investigations into several Play ransomware intrusions where the common entry vector was confirmed to be Microsoft Exchange .


EventBot screenPinPrefs.xml The content of screenPinPrefs.xml . The malware was first seen packed with VMProtect; when unpacked the sample didn’t show any similarities with previously known malware . The macro ran a PowerShell command that attempted to download additional PowerShell loader scripts for PupyRAT , a research and penetration-testing tool that has been used in attacks .


Hermes ransomware , the predecessor to Ryuk , was first distributed in February 2017 . When conducting programmatic espionage activity , it can presumably become quite confusing if the attacker targets a heavy industry company , an avionics program , and seven other unique targets as to which infected host you will collect what information from .


Our research team analyzed the malicious Android application that is most likely being spread by TrickBot and dubbed it “ TrickMo. ” Targeting users in Germany at this time , TrickMo is the latest variation in the transaction authentication number ( TAN ) -stealing malware category . Analysis of the emails has shown that the attachment contains an exploit for the CVE-2017-11882 vulnerability . Interestingly , the targeted organization in the January 16 attack had already been targeted by the OilRig group a year ago on January 2017 .


Today we are sharing this information to raise awareness of these risks across the industry and calling for better enterprise integration of IoT devices , particularly the ability to monitor IoT device telemetry within enterprise networks .


The files uploaded to this webshell included the same compiled python script that would scan remote systems that were vulnerable to CVE-2017-0144 (EternalBlue) that we saw uploaded to the other errr.aspx webshell . Another decoy slideshow associated with the Bookworm attack campaign contains photos of an event called Bike for Dad 2015 .


Therefore , the Stuxnet MOF file creation tool that the Shadow Brokers dropped on Friday is possibly the earliest technical evidence that NSA hackers and developers coded Stuxnet , as many suspect . We noted in our original blog the large amount of targeting of Iranian citizens in this campaign , we observed almost one-third of all victims to be Iranian .


Finally , depending on how interesting the victim is , they malware operators may deploy another custom backdoor .


These characteristics suggest that the threat group is well resourced and has access to a tools development team and a team focused on SWCs .


Chrysaor is spyware believed to be created by NSO Group Technologies , specializing in the creation and sale of software and infrastructure for targeted attacks . Our investigation of Leafminer started with the discovery of JavaScript code on several compromised websites in the Middle East . APT33 : 192.119.15.40 [REDACTED].ddns.net . None Ensure X - Forwarded - For header is configured to log true external IP addresses for request to proxied services .


Microsoft Threat Intelligence refers to the activity group behind these attacks as TERBIUM , following our internal practice of assigning rogue actors chemical element names . We believe that the Carbanak campaign is a clear indicator of a new era in cybercrime in which criminals use APT techniques directly against the financial industry instead of through its customers .


Secondly , some of the MiniDuke components do not contain a hardcoded C&C server address , but instead obtain the address of a current C&C server via Twitter .


In the most recent case , the choice of the payload zip file depends on the device process architecture . We identified two methods to deliver the KerrDown downloader to targets . The group is known for frequently changing malware and driving global trends in criminal malware distribution .


The other overlapping files are tools used by the adversary to locate other systems on the network etool.exe , check to see if they are vulnerable to CVE-2017-0144 (EternalBlue) patched in MS07-010 checker1.exe and pivot to them using remote execution functionality offered by a tool similar to PsExec offered by Impacket psexec.exe . The Tropic Trooper threat actor group has been known to target governments and organizations in the Asia Pacific region for at least six years .


The fact the trojan can steal both the victim ’ s credentials and also can control their SMS messages and generated 2FA codes means DEFENSOR ID ’ s operators can bypass two-factor authentication . On June 18 , the majority of the campaign’s spam emails were sent with the subject , Your RAKBANK Tax Invoice / Tax Credit Note” or Confirmation . This new campaign , dubbed HaoBao , resumes Lazarus ' previous phishing emails , posed as employee recruitment , but now targets Bitcoin users and global financial organizations .


WannaCry appends encrypted data files with the .WCRY extension , drops and executes a decryptor tool , and demands $300 or $600 USD ( via Bitcoin ) to decrypt the data . As mentioned in our previous blog on Bookworm , the Trojan sends a static date string to the C2 server that we referred to as a campaign code .


We have observed this trojan being submitted to public antivirus testing platforms , once as a package and once for each DLL to determine the detection ratio . LYCEUM delivers weaponized maldocs via spearphishing from the compromised accounts to the targeted executives , human resources (HR) staff , and IT personnel . We can confirm that the APT38 operator activity is linked to the North Korean regime , but maintains a set of common characteristics , including motivation , malware , targeting , and TTPs that set it apart from other statesponsored operations .


One such interesting example was “ ПЛАН_РЕАЛИЗАЦИИ_ПРОЕКТА.rar ” ( SHA256 b5c208e4fb8ba255883f771d384ca85566c7be8adcf5c87114a62efb53b73fda ) .


Specifically , the targeting of organizations in the aerospace and energy sectors indicates that the APT33 is likely in search of strategic intelligence capable of benefitting a government or military sponsor . In August 2014 , some of our users observed targeted attacks with a variation of CVE-2012-0158 and an unusual set of malware .


Capabilities and functionality In 2013 , we detected several technological innovations developed and used by criminals in their malicious software . TAA triggered an alert at a large telecoms operator in Southeast Asia . Notice the “ Servcie ” typo . Based on these symbols , Mandiant assesses with moderate confidence that com.docker.vmnat was a version of the FULLHOUSE.DOORED backdoor .


The encrypted body is composed of various identifiers which are joined together : doFinal ( ) is called to encrypt the device information string : The user agent string is built from the package name and IMEI number : Finally the HTTP request is sent to the server at https : //54.71.249.137/eddd0317-2bdc-4140-86cb-0e8d7047b874 . ISMDoor is able to exfiltrate data , take screenshots , and execute arbitrary commands on the victim 's machine . The malicious documents , the droppers and the RAT itself are developed around cloud providers . The PDF usually named “ CriticalBreachDetected.pdf ” is generated using content embedded in the ransomware binary , including the skeleton PDF and the ransom note .


As mentioned in the Hermes to Ryuk section , Ryuk uses a combination of symmetric ( AES ) and asymmetric ( RSA ) encryption to encrypt files . Securelist believe the attacks are launched by an APT Group we track under the codename " ScarCruft " .


Device registration This is the last of the three main timers that are created . More recently , ITG08 has been observed targeting e-commerce environments by injecting malicious code into online checkout pages of compromised websites — a technique known as online skimming — thereby stealing payment card data transmitted to the vendor by unsuspecting customers . In May 2017 , APT37 used a bank liquidation letter as a spear phishing lure against a board member of a Middle Eastern financial company .


This is a better implementation , as it allows servers and clients from different versions to communicate with each other to some extent .


It even has its own virtual keyboard that supposedly protects the victim from keyloggers . MXI Player appears to be a version of the Bahamut agent , designed to record the phone calls and collect other information about the user ( com.mxi.videoplay ) . Active since at least 2014 , this actor has long-standing interest in maritime industries , naval defense contractors , and associated research institutions in the United States and Western Europe .


Malicious iOS profile In the case of Apple devices , the downloaded malicious iOS profile gathers the following : Unique device identifier ( UDID ) International Mobile Equipment Identity ( IMEI ) Integrated Circuit Card ID ( ICCID ) Mobile equipment identifier ( MEID ) Version number Product number The profile installations differ depending on the iOS . Numbered Panda has a long list of high-profile victims and is known by a number of names including : DYNCALC , IXESHE , JOY RAT , APT-12 , etc . When set in text receive mode, the malware uses the AdrGen function to create another query string with the r (receiver) flag and a W (wait) action . At Talos , we pride ourselves on the quality of the intelligence we publish .


After making headlines during 2016 due to its involvement in cyber attacks against an organization involved in the U.S. presidential election , APT28 ( aka Swallowtail , Fancy Bear ) has continued to mount operations during 2017 and 2018 .


The attack group then used these stolen credentials to gain access to the DNC network , install malware , move across the network , and steal data , including a trove of emails .


We 've seen this actor rely heavily on phishing campaigns to trick victims into downloading their malicious apps , specifically on Facebook . The DeltaCharlie DDoS bot was originally reported by Novetta in their 2016 Operation Blockbuster Malware Report . However, starting from 7Zip version 9.34 (next available installer after version 9.22) up to its latest version 19.0, 7zip saw and was able to extract the image file order.jpg . Second , as COSMICENERGY was potentially developed as part of a red team , this discovery suggests that the barriers to entry are lowering for offensive OT threat activity since we normally observe these types of capabilities limited to well resourced or state sponsored actors .


Last week iSIGHT 's sources provided us with the same KillDisk malware published by Rob Lee of SANS and Dragos Security . Mark Zuckerberg , Jack Dorsey , Sundar Pichai , and Daniel Ek — the CEOs of Facebook , Twitter , Google and Spotify , respectively — have also fallen victim to the hackers , dispelling the notion that a career in software and technology exempts one from being compromised .


∗ android.permission.WRITE_SETTINGS ( read/write global system settings ) ∗ android.permission.RECEIVE_SMS ( intercept SMS messages ) ∗ android.permission.READ_PHONE_STATE ( read phone details of the device such as phone number and serial number ) ∗ android.permission.CHANGE_WIFI_STATE ( connect to and disconnect from Wi-Fi networks and make changes to configured networks ) ∗ android.permission.READ_CONTACTS ( read all contact data ) * android.permission.READ_SMS However , the attack is different in two respects : unlike other APTs , the main focus of Blue Termite is to attack Japanese organizations ; and most of their C2s are located in Japan . Organizations with high financial or intellectual property value should take the time to ensure their security requirements are met and that employee ’s are educated about the security threats their organizations face . In addition to the complexity of managing CSP rules , this vulnerability shows how widely used services such as Google Analytics can be subverted to bypass this protection .


From there , root-level apps can read or modify data and resources that would be off-limits to normal apps . CTU researchers also identified components in the custom C2 protocol being used ( the way in which the malware talks to the Command and Control Servers ) which they have seen utilized by Nickel Academy ( Lazarus ) previously . APT33 : 192.119.15.35 mynetwork.ddns.net . The group itself likes to pretend to be a cybersecurity organization as shown in the ransom note below .


is very similar to newer ones , but it provides additional insights being not obfuscated : Firstly we can notice that , instead of generic domain names or IP addresses , these samples communicated with a Command & Control server located at attiva.exodus.esurv [ . Based on the command capabilities of the Taidoor malware , we were able to determine that data theft and data destruction was possible . Downloads additional payloads . Limited forensic evidence existed to determine exactly how STRATOFEAR was deployed to systems in the victim environment ; however , in each instance , STRATOFEAR was preceded by the deployment of FULLHOUSE.DOORED .


CTU researchers have no evidence of other threat actors using RCSession or of wide proliferation of the tool , suggesting it may be exclusively used by BRONZE PRESIDENT .


Assuming these checks pass , one of the main ELF libraries is loaded that orchestrates other components and provides functionality to the app ’ s Dalvik code through the Java Native Interface ( JNI ) . APT41 activity aimed at medical device companies and pharmaceuticals is demonstrative of the group's capacity to collect sensitive and highly valuable intellectual property (IP) , although we have not observed evidence of IP theft since late 2015 . APT28 espionage activity has primarily targeted entities in the U.S. , Europe , and the countries of the former Soviet Union , including governments and militaries , defense attaches , media entities , and dissidents and figures opposed to the current Russian government .


This is similar to the way in which the toolset was being spread via trojanized applications in torrent files during the summer of 2013 .


A good write-up from 2014 on the malware can be found in this writeup from Yury Namestnikov , Vladimir Kuskov , Oleg Kupreev at Kaspersky Lab here and indicates that the returned data is an RC4 encrypted loader that sets-up the main Chthonic module which can download additional modules or malware .


“ In the future , we can expect that the bad guys will try to make use of Facebook statuses or deploy LinkedIn and other social networks ” , states ESET ’ s researcher . Just as with romance scams , actors make use of scripts and templates they can copy-and-paste without having to create something on their own . To date , the Lazarus group has been one of the most successful in launching large scale operations against the financial industry .


The kit we found is in tgz format , though we have observed some samples disguised as png or jpg .


The high level flow of the exploit is as follows :


The Trojan has evolved since then , aided by a large-scale distribution campaign by its creators ( in spring-summer 2017 ) , helping Asacub to claim top spots in last year ’ s ranking by number of attacks among mobile banking Trojans , outperforming other families such as Svpeng and Faketoken . Of note , this methodology of naming abstracts away the " who " element – XENOTIME may represent a single discrete entity ( such as a Russian research institution ) or several entities working in coordination in a roughly repeatable , similar manner across multiple events . Based on the Ukranian language embedded in the backdoor , Cybereason raises the possibility that the backdoor was obtained in underground communities by the threat actors , rather than developed in-house by the group . The trojan acted like a legitimate application or file in order to trick users into running it .


Email account A Gmail account with password is mentioned in the sample ’ s code : It contains the victim ’ s exfiltrated data and “ cmd ” directory with commands for victim devices . We analyzed a new RATANKBA variant ( BKDR_RATANKBA.ZAEL–A ) , discovered in June 2017 , that uses a PowerShell script instead of its more traditional PE executable form—a version that other researchers also recently identified . APT33 : 91.235.142.76 mywinnetwork.ddns.net . If the target system met predefined requirements , the malware used Twitter to look for specific tweets from pre - made accounts created by MiniDuke ’s command and control ( C2 ) operators , with specific tags labeling encrypted URLs for backdoors .


pointer from its own process environment block ( PEB ) ( Note : The KernelCallbackTable points to an array of graphic functions used by Win32 kernel subsystem module win32k.sys as call-back into user-mode . As described in previous publications , the Rocket Kitten attackers make extensive use of various phishing schemes . Once kernel32 base is found , the shellcode will calculate the addresses of LoadLibraryA and GetProcAddress functions , and use them to resolve other necessary APIs , which include VirtualAlloc , RtlMoveMemory , and RtlZeroMemory . Further analyses of these similarities are available via Mandiant Advantage .


If the original SMS app has been restored , it will send “ the app returned to its original place. ” Controlling TrickMo TrickMo ’ s operators can control the malware via two channels : Through its C & C via a plaintext HTTP protocol using JSON objects Through encrypted SMS messages There are predefined commands to change the malware ’ s configuration and make it execute certain tasks . PUTTER PANDA is a determined adversary group , conducting intelligence-gathering operations targeting the Government , Defense , Research , and Technology sectors in the United States , with specific targeting of the US Defense and European satellite and aerospace industries . Symantec has found evidence of Starloader files being named AdobeUpdate.exe , AcrobatUpdate.exe , and INTELUPDATE.EXE among others .


With the increased use of Android phones in business environments , it is important to defend against these threats by ensuring devices are kept current with the latest updates . The victims for the 2014-2015 versions are generally IT and real estate/investment companies and in both cases , a small number of computers have been infected throughout Wild Neutron . In addition , we analyzed the victims of this campaign and spotted an interesting overlap of this campaign with another APT actor known as DarkHotel . There are different installation flows for this campaign , but we will focus on the one that uses a URL shortcut .


Most of the affected devices were located in the Middle East , and many of the stolen data we saw is military-related ( e.g. , images , documents ) . The ScarCruft APT gang has made use of a Flash zero day patched Thursday by Adobe to attack more than two dozen high-profile targets in Russia and Asia primarily . The major error made by its operators allowed us to follow the command and control server of the GRIFFON implant last year . Any Greatness affiliates do n’t need a specific set of skills .


However , successfully installing this malicious APK requires that the user has allowed the installation of such apps as controlled in the Unknown Sources settings . FireEye said it has tracked admin@338 's activity since 2013 and the group has largely targeted organizations involved in financial , economic and trade policy . Based on the code, it is unclear what initiates the Visual Basic script . On April 21 , 2022 , KillNet also stated that " REVIL is back in the ranks . "


Copy the stage 5 DLL into winlogon.exe Allocate a chunk of memory in winlogon.exe process and copy the same APC routine seen previously Read and save the original pointer of the __fnDWORD internal User32 routine ( located at offset +0x10 of the KernelCallbackTable ) and replace this pointer with the address of the APC stub routine After this function pointer hijacking , when winlogon.exe makes any graphical call ( GDI ) , the malicious code can execute without using CreateRemoteThread or As the Rocket Kitten group 's behavior was well characterized in previous publications ( see the recent report from Trend Micro and ClearSky ) . MZ header , PE header , as well as each section and their header , are decrypted separately using RC4 algorithm and a hardcoded key . UNC2529 has also used weaponized Microsoft Excel documents as a first stage downloader .


Due to these changes without a new date string , we believe the date codes are used for campaign tracking rather than a Bookworm build identifier . If the user enables macro to open the xlsm file , it will then drop the legitimate script engine AutoHotkey along with a malicious script file .


For this purpose , the app receives from the C & C server the isGoogleIp flag , which indicates whether the IP address of the affected device falls within the range of known IP addresses for Google servers . Finally , Kaspersky produced a summary report on Sofacy’s summertime activity . When the attacker wants to gather information on the infected system (action 5) , it retrieves the following information: Hostname IP address Computer name Username name Connected drive OS version Architecture Start menu programs Installed software .


FakeSpy package permissions . Its purpose remains to manipulate financial assets , such as transferring funds from bank accounts or taking over ATM infrastructures and instructing them to dispense cash at predetermined time intervals . Unit 42 researchers have been tracking an active campaign .


A recent report documents a group of attackers known as " PittyTiger " that appears to have been active since at least 2011 ; however , they may have been operating as far back as 2008 . By analyzing the attack infrastructure , Group-IB identified that MoneyTaker group continuously exfiltrates internal banking documentation to learn about bank operations in preparation for future attacks .


What ’ s more , the user can not check the balance via mobile banking or change any settings there , because after receiving the command with code 40 , the Trojan prevents the banking app from running on the phone . After compromising an initial victim 's system ( patient 0 ) , the threat actors use the Baidu search engine to search for the victim 's organization name . We think the group has likely become more enterprising , and learned to take advantage of some details from their previous campaigns to maximize profit opportunities while exerting minimal effort .
