Affiliates are tasked with gaining initial access to the victim network, allowing LockBit 2.0 to conduct the rest of the attack. | [] | LockBit 20 How This RaaS Operates and How to Protect Against It |
LockBit 2.0 has been observed changing infected computers’ backgrounds to a ransomware note. | [] | LockBit 20 How This RaaS Operates and How to Protect Against It |
The ransomware note was also used to recruit insiders from victim organizations. | [] | LockBit 20 How This RaaS Operates and How to Protect Against It |
The notes claimed the threat actors would pay “millions of dollars” to insiders who provided access to corporate networks or facilitated a ransomware infection by opening a phishing email and/or launching a payload manually. | [] | LockBit 20 How This RaaS Operates and How to Protect Against It |
The threat actors also expressed interest in other access methods such as RDP, VPN and corporate email credentials. | [
