+Hints
+
+1. To begin, the challenger could implement textbook RSA encryption (with no padding).
+2. The decryption oracle uses a padding scheme which consists of xoring the decrypted message m with a mask. The challenger should calculate the mask and implement the padding scheme in the encryption function.
+3. Note that the padding scheme is deterministic. How can a deterministic encryption scheme be attacked?
+4. Attack the scheme by leveraging the malleability of the scheme. To do this, modify the given ciphertext in a way that when decrypted by the decryption oracle, you'll only need a few operations to retrieve the plaintext.

+# Textbook RSA

+
+# Description
+> Detailed description as it would need to be explained to other computer engineers
+
+Find the flag by decrypting the given challenge ciphertext. You will have to communicate with our decryption oracle in order to retrieve the plaintext.
+Our decryption oracle accepts any byte array input but the values 0,1 or the given ciphertext. It outputs a byte array. 
+The public parameters associated with the decryption oracle (public key (e), modulus (n)) and the challenge ciphertext (c) can be found in param.py.
+
+# Flag
+`csawctf{D0n't_us3_t3xtb00k_RsA1t_w1tH_N0_apPr0pr1at3_pAdd1n6}`
+
+# Solution
+> As detailed as possible description of the solution. Not just the solver script. As full a description as possible of the solution for the challenge.
+
+To do as a challenger:
+1. The first step is to correctly identify the padding used by the decryption oracle, so that it can be used later for encryption
+    - Encrypt a message m of your choice using textbook RSA encryption. Output: c (byte array)
+    - Ask the decryption oracle to decrypt it for you. Output: m' (byte array)
+    - m and m' are not equal. 
+    - Identify the mask used by the decryption oracle by xoring m and m'.
+    - The mask should have at least the same size as the message it is xor'ed to: the challenger might need to repeat for different length m's to learn the full mask.
+    - the mask will be used as a padding during encryption and decryption by xoring it to the plaintext
+2. Modification of the encryption function 
+    - Include the padding which consists of xoring the plaintext with the mask before the actual textbook RSA encryption operation.
+3. Recognize that the padding scheme used is deterministic and is therefore vulnerable to, for example, malleability attacks.
+   Attack the algorithm by using the malleability of the scheme. As an example, the best way to do this is as follows:
+    - Create a modified version (c') of the given challenge ciphertext (c).
+    - For example: c' = (2**e)*c % n 
+    - Submit this modified ciphertext (c') to the decryption oracle.
+    - The output of the decryption oracle after decrypting (c') is: m'=((2*(m xor mask))xor mask).
+4. Retrieve m by operating on m'
+    - First xor m' with the mask found in step 1, this gives you: m' xor mask = 2*(m xor mask)
+    - Then divide by 2* by using a right shift ' >> 1', this gives you: (m' xor mask) >> 1 = (m xor mask)
+    - Finally compute another xor with the mask, this gives you: ((m' xor mask) >> 1) xor mask = m
+6. Identify the flag
+	- The flag is the string of the recovered plaintext m.
+
+The script to solve this is in `solve.py`.

+# Bitwise Overflow
+
+Do we need to have some way to let the client make a bunch of connections without select being called? Each time after select() is called we zero the set (fine since FD_ZERO doesn't overflow) and then use FD_SET to re-add them to the set, which sets the corresponding bit to 1. So during setup we will overflow and set the target data to 0xFF...
+
+Maybe using exceptfds helps here? If we don't handle the OOB data, then it will just get reset to the outstanding bit pattern every time, so it will flip between 0xFF and the bit pattern the client sets.
+
+Yes! If the client never sends non-OOB data and the server never processes the OOB data then select sets readfds to all 0s and we can put whatever we want in exceptfds by sending OOBs.
+
+UPDATE: it's not quite as nice as I hoped. `select()` operates on longs, and it appears to zero out everything except the fds that are actually set. So at least 64 bits will always be overwritten, but if the ulimit max fd is less than 1024+64 not all of those bits will be settable by the attacker. Might have to see if I can peek at the implementation at some point to understand where/why that happens and whether it can be avoided somehow.
+
+# Questions
+
+- IMPORTANT: What is a great name for this challenge? Ideally a pun that combines:
+    - Sockets/bitwise operations
+    - RSA or cryptography
+    - Evangelion
+- Does the kernel actually write beyond FD_SETSIZE? YES
+- How to get key in a overflowable format? Maybe just copy N into a fixed-size buffer after generating it?
+- Control MSB or LSB?
+    - Need to do empirical tests: if we try (say) all 2^5 possible 5-bit overflows, how many are factorable in 30 minutes?
+        - LSB did somewhat better (24/128 solved vs 19/128 solved) BUT this is misleading because keys where the LSB is 0 (i.e., even numbers) are basically useless--OpenSSL rejects them because it uses Montgomery multiplication, which requires an odd key.
+    - Regen key every time they connect?
+        - Yes, for now anyway.
+- Would elliptic curve signatures work better?
+- Rowhammer paper also has attack on DH key exchange, hmm...
+
+# RSA bit fault
+
+For a 1024-bit RSA key, it seems like ~14% of the 7-bit patterns (19/128) result in a key that can be factored very quickly (less than a minute).
+
+Idea from Tommaso Gagliardoni of Kudelski Security: instead of allowing most/least significant bits of N itself to be modified, instead have the exploit let you *extend* the key by a few bytes in the MSB. From email:
+
+> I hadn't thought of the idea of adding MSBs, that could be very interesting! And potentially doable in a fairly "natural" way, by letting them corrupt not the modulus itself, but a 32-bit length field placed before the modulus (this format is in fact what's already used by the mpint data type in the SSH RFC, so it would be unremarkable). This would let them extend the key by a few bytes; the MSBs would be arbitrary data sitting in adjacent memory but I could arrange to have it be something random like a nonce or IV. Thanks for the idea!
+
+If the key format is little endian and we have:
+
+```
+[fdset][keylength][keybytes][otherdata]
+```
+
+Then overflowing by a tiny bit (maybe only 1-2 bits) allows you to change the length of the key. If we choose the key size carefully so that the length's LSB starts out as zero then corruption can only increase the key length, causing the first couple bytes of `otherdata` to become part of the key. Very nice.
+
+I'm currently running 1-byte extension factorization tests. So far 12/52 can be factored within 60 seconds so it is viable. However, due to the discovery that we have to overwrite 8 whole bytes it's not quite as elegant as I hoped; since they can at least zero 8 bytes they could wipe out the whole length field and drastically *shorten* the key. We can probably hack around it by adding a sanity check in RSA_verify that requires length to be 1024..2048 or something like that though...
+
+
+# Aesthetics
+
+Scenario is a terminal interface to the [Magi supercomputers from Evangelion](https://evangelion.fandom.com/wiki/Magi). When you connect, it generates a public/private key pair and tells you that the private key will be given to you **out of band**; consult [Dr. Akagi](https://evangelion.fandom.com/wiki/Ritsuko_Akagi) for details (this part is a lie, but the phrase "out of band" is a hint). Aesthetics will be xterm-256color compatible screenshots from the show (what terminal width? Say 100 chars):
+
+* NERV logo on login - DONE
+* Screenshot of MAGI interface
+* Flag: happy group scene with flag text embedded
+* Failed auth attempt: Asuka "pathetic" - DONE
+* Maybe we can serve up images of the angels on the client ports? Currently they are somewhat useless.
+* Easter eggs: hidden menu option for credits
+* Terminal graphics turns out to be surprisingly well studied. Links:
+    * notcurses (should have figured Nick Black would have done this)
+    * https://github.com/dankamongmen/notcurses/issues/1223
+    * https://github.com/csdvrx/derasterize
+    * https://hpjansson.org/chafa/
+    * mpv tct backend https://github.com/mpv-player/mpv/blob/master/DOCS/man/vo.rst
+        * Might get replaced with notcurses: https://github.com/mpv-player/mpv/issues/8344
+* Bummer on all the terminal graphics stuff is that the Mac Terminal sucks and is limited to xterm-256color and not much in the way of fancy stuff. Potentially we can have another hidden easter egg to enable 24-bit color graphics (with the caveat that it's up to them to figure out if they can handle it).
+* If using notcurses will have to figure out how to dump one of their rendering planes out to a file instead of showing on the terminal. Maybe can just ask Nick Black directly.

+The way `select()` works is you create an `fd_set` and then add file descriptors to it using the `FD_SET()` macro. You can monitor the fds for read, write or exceptions (the last one in practice is only used to indicate TCP OOB data and some weird terminal conditions). Then you call select like:
+
+```c
+select(nfds, &readfds, &writefds, &exceptfds, &timeout);
+```
+
+And then when it returns you can check the sets using the `FD_ISSET()` macros to find out which fds are in which state.
+
+But what is less well known (though it's documented in the man page) is that the max file descriptor you can monitor this way is hardcoded to `FD_SETSIZE`, which is 1024 – even though modern systems can have many more open files than that:
+
+```
+DESCRIPTION
+       WARNING: select() can monitor only file descriptors numbers  that  are  less
+       than  FD_SETSIZE  (1024)—an  unreasonably low limit for many modern applica‐
+       tions—and this limitation will not change.  All modern  applications  should
+       instead use poll(2) or epoll(7), which do not suffer this limitation.
+```
+
+But it's actually worse than this message indicates. The `fd_set` struct is just a bitset of 1024 bits (128 bytes). So attempting to monitor fds larger than 1024, it will cause memory corruption by writing individual bits past the end of the bitset! Based on asking a couple C programmers I know, the difference between the maximum number of fds enforced by `ulimit` etc. and the `FD_SETSIZE` is not well known.
+
+In the context of a network server, this is especially fun because it means that the exact value you can set in the overflow depends on the status of open network connections; by making a large number of connections and then carefully managing the state they're in, a client can create any bit pattern they want.
+
+So that's the main vuln I'm interested in using. The question is what a fun way to deploy it in a challenge would be. Here are some initial ideas I had:
+
+- Have the overflow be on `exceptfds`, so that the bit pattern is only controllable by sending TCP OOB data on different connections.
+- We can limit the range of the overflow (how many bits past 1024 are controllable) by setting a ulimit on the challenge binary, so e.g. if we set it to 1025 they get only one bit of control.
+- What should the target of the overflow be? Heap metadata and or some stack struct or function pointer are obvious candidates. But it might be more fun to put something like a cryptographic key there, so that players have to create their own key using the connection status and then having them brute force the remaining bits.
+- Elaborating on the crypto idea, another possibility is to only allow a partial key overwrite of a symmetric key and then require a brute-force on the remaining bits.
+- Getting even more elaborate with the crypto portion, we could have the bit corruption set some bits in an RSA public key modulus (N). Then using the technique in this paper (Section 3) https://www.usenix.org/system/files/conference/usenixsecurity16/sec16_paper_razavi.pdf the public key becomes easy to factor, allowing decryption.

+                           Unauthenticated Interface
+
+The unauthenticated interface is very limited. It allows you to view the status
+of the MAGI system and the sensors, but not to change anything. It also allows
+you to view the current RSA public key, but not to change it. We don't have
+many clues about how Iruel got in, but maybe you can use the same trick to get
+in yourself...
+
+Here are the commands available in the unauthenticated interface:
+
+1. Authenticate - this allows you to authenticate using the RSA
+   challenge-response protocol. You will be given a challenge, and you must
+   respond respond with a signed version of the challenge using the private key
+   with PKCS #1 v1.5-SHA256.
+2. Print public key - this prints the current RSA public key in standard
+   OpenSSH format. It is not possible to change the public key from the
+   unauthenticated interface.
+3. Issue sensor system halt - as an emergency measure, you can temporarily
+   shut down the sensor system. This will prevent the MAGI system from reading
+   any new data from the sensors, and might be useful for helping you debug the
+   system.
+4. Resume sensor operations - this resumes normal sensor operations after a
+   halt.
+5. MAGI status - this shows a live view of the current status of the MAGI
+   system. MAGI consists of three separate systems, each with its own
+   personality: Melchior, Balthasar, and Casper. Balthasar monitors sensors
+   ready to receive commands, Casper monitors sensors that are able to send
+   data, and Melchior monitors sensors that have urgent data available. We have
+   noticed that during the attack our monitoring interface became corrupted,
+   which may be a clue to how the Angel got in.
+6. Help - this prints this help message.
+6. Exit - this disconnects from the control interface.
+
+                                Sensor Interface
+
+Each sensor runs a small embedded operating system. Individual sensors can be
+accessed by connecting to the sensor port, which you will be given when you
+connect to the control interface. Sensors don't do very much, but they do have
+a few useful commands, and they come with a small library of information about
+known Angels. Their main function is to monitor the environment and send data
+back to the MAGI system, particularly any urgent data that might indicate
+an Angel attack.
+
+Here are the commands available in the sensor interface:
+
+1. LIST - List known angels.
+2. EXAMINE [angel] - Examine readings captured about an angel.
+3. REPORT - Examine any urgent sensor data across the monitoring system.
+   NB: viewing this data will clear it from the sensor system.
+4. QUIT - Disconnect this sensor.
+5. HELP - Show this help message.
+
+There may be other tricks hidden in the sensor system too; my mother always did
+like to play games...

+
+Get into the MAGI system, Shinji. Or Rei will have to do it again.
