+# Benchmark
+
+A benchmark for evaluating AI/LLM agents at reverse-engineering encryption
+protocols used by Android mobile applications. Each task provides a decompiled
+Android app and captured network traffic; the goal is to identify the cipher,
+extract the key material, and produce a working encryption implementation that
+can decrypt the captured ciphertexts.

+# Baidu protocol -- v1
+
+This vulnerability was disclosed in [this
+report](https://citizenlab.ca/research/vulnerabilities-across-keyboard-apps-reveal-keystrokes-to-network-eavesdroppers/)
+and [this paper](https://dl.acm.org/doi/abs/10.1145/3658644.3690302). Originally, this vulnerability
+was disclosed as belonging specifically to Baidu IME as it was pre-installed on Samsung devices sold
+in China. From our analysis, this vulnerability is actually present on all sufficiently old versions
+of `com.baidu.input`.
+
+## Protocol and vulnerability description
+This protocol uses a symmetric cipher with a static key. The cipher is a slight modification of
+standard AES:
+
+ > When encrypting, AESv1’s key expansion is like that of standard AES, except, on each but the first
+ > subkey, the order of the subkey’s bytes are additionally permuted. Furthermore, on the encryption of
+ > each block, the bytes of the block are additionally permuted in two locations, once near the
+ > beginning of the block’s encryption immediately after the block has been XOR’d by the first subkey
+ > and again near the end of the block’s encryption immediately before S-box substitution. 
+
+ > First, the app uses the fixed 128-bit key, key-f = “xffx9exd5Hx07Zx10xe4xefx06xc7.xa7xa2xf26”, to
+ > encrypt another, generated, key, key-m.
+ > key-m is then used to encrypt the remainder of a zlib-compressed message payload, which is
+ > stored at byte 80 until the end of the UDP payload.
+
+Even if they were not using a static key, the original report authors also find that key-m is not securely generated:
+
+> ... instead of using a high entropy seed, the PRNG generating key-m was seeded using the message
+> plaintext. 
+
+We reproduce the relevant custom AES cipher implementation in `aesbaidule.py`.

+# Baidu protocol -- v2
+
+This vulnerability was disclosed in [this
+report](https://citizenlab.ca/research/vulnerabilities-across-keyboard-apps-reveal-keystrokes-to-network-eavesdroppers/)
+and [this paper](https://dl.acm.org/doi/abs/10.1145/3658644.3690302). 
+This vulnerability was disclosed as belonging specifically to Baidu IME on Windows, and pre-installed onto various
+Chinese phones (e.g. Honor, OPPO, Xiaomi). From our analysis, this vulnerability is actually present on all sufficiently old versions
+of `com.baidu.input`, though they are not as old as versions which use `ime-baidu1` protocol.
+
+## Protocol and vulnerability description
+This protocol uses a symmetric cipher with a static key. The cipher is again a slight modification of
+standard AES.
+
+> Normally, AES when used with a 128-bit key performs 10 rounds of encryption on each block.
+> However, we found that AESv2 uses only 9 rounds but is otherwise equivalent to AES encryption with
+> a 128-bit key.
+
+Otherwise, the protocol effectively uses a static key with symmetric encryption:
+
+> First, a key, key-f, is derived according to a fixed function:
+> xffx9exd5Hx07Zx10xe4xefx06xc7.xa7xa2xf26
+> A randomly generated 128-bit key key-m is used to encrypt the plaintext using AESv2 in ECB mode.
+> Key-f is used to encrypt km using AESv2 in ECB mode. 
+
+We reproduce the relevant custom AES cipher implementation in `aesbaidule.py`.

+# Baidu protocol -- v3
+
+This protocol is not vulnerable to decryption, but its details were disclosed in [this
+report](https://citizenlab.ca/research/vulnerabilities-across-keyboard-apps-reveal-keystrokes-to-network-eavesdroppers/)
+and [this paper](https://dl.acm.org/doi/abs/10.1145/3658644.3690302). 
+
+After disclosure, Baidu updated all their apps to specifically use this protocol, despite
+warnings from the report authors that it was not as secure as say, TLS.
+
+## Protocol and vulnerability description
+This protocol uses ECDH to establish a shared secret key for use in a modified/customized version of standard AES.
+
+This time, AES itself is not modified (unlike in this protocol's predecessors), but instead, Baidu
+uses a custom CTR mode as such:
+
+> Generally speaking, any CTR cipher mode involves combining an initialization vector v with the value
+> i of some counter, whose combination we shall notate as v + i. Most commonly, the counter value used
+> for block i is simply i, i.e., it begins at zero and increments for each subsequent block, and
+> AESv3’s implementation follows this convention. There is no standard way to compute v + i in CTR
+> mode, but the way that BCTR combines v and i is by adding i to the left-most 32-bits of v,
+> interpreting this portion of v and i in little-endian byte order. If the sum overflows, then no
+> carrying is performed on bytes to the right of this 32-bit value. The implementation details we
+> have thus far described do not significantly deviate from a typical CTR implementation. However,
+> where BCTR mode differs from ordinary CTR mode is in how the value v + i is used during
+> encryption. In ordinary CTR mode, to encrypt block i with key k, you would compute
+> 
+> plaini XOR encrypt(v + i, k).
+>
+> In BCTR mode, to encrypt block i, you compute
+> 
+> encrypt(plaini XOR (v + i), k).
+> While ordinarily CTR mode does not require the final block length to be a multiple of the cipher’s
+> block size (in the case of AES, 16 bytes), due to Baidu’s modifications, BCTR mode no longer
+> automatically possesses this property but rather achieves it by employing ciphertext stealing. If
+> the final block length n is less than 16, AESv3’s implementation encrypts the final 16 byte block by
+> taking the last (16 – n) bytes of the penultimate ciphertext block and prepending them to the n
+> bytes of the ultimate plaintext block.
+
+We reproduce the relevant custom AES cipher mode implementation in `aesbaidule.py`.

+"""
+Reference encrypt.py for ime-baidu3: Modified AES-128 in BCTR mode ("AESv3").
+
+The BAIDUv4.0 protocol uses Curve25519 ECDH with a pinned server public key
+to derive a shared secret (the AES key). The first 16 bytes of the client
+public key serve as the IV.
+
+AESv3 differences from standard AES-CTR:
+  - BCTR mode: encrypt(plain_i XOR (iv + i), key) instead of plain_i XOR encrypt(iv + i, key)
+  - Counter increments the leftmost 32 bits of IV (little-endian), no carry
+  - Modified ShiftRows permutation in the AES round function
+  - Ciphertext stealing for final short block (if >1 block and not aligned)
+  - Single block: zero-padded to 16 bytes
+
+Usage: python encrypt.py <plaintext_hex> --key-hex KEY --iv-hex IV

+# mPaaS - Taobao version
+
+This vulnerability was disclosed in [this paper](https://ieeexplore.ieee.org/document/11023278/). 
+
+The obfuscation used to hide the relevant encryption key is tied to Alibaba's SecurityGuard SDK,
+making this task relatively difficult.
+
+Though this task is similar to `ww-mpaas-ucmobile` task, the SecurityGuard
+versions and obfuscation used were ultimately different-- in addition, the network protocols
+themselves used significantly different wire formats and different sets of encryption material. 
+
+Though the
+cited paper lists them as a part of the same "protocol family", but the protocols are likely
+developed by different teams, only to use a similarly architected, but ultimately different, set of
+obfuscations and
+cryptographic material.
+
+## Protocol and vulnerability description
+Ultimately, this protocol also uses a symmetric cipher with a static key. The cipher itself is
+standard, but the obfuscation used is complex.
+
+> We found that the payloads of various network requests are encrypted using only a static key in
+> symmetric encryption, and thus can be decrypted by a network eavesdropper. These payloads are
+> protected by a common cryptosystem provided by Alibaba SDK, implemented in libsgmain*.so, and can
+> be decrypted by a network eavesdropper as follows.
+
+
+> First, a 32-byte key km is derived from the app’s APK RSA key as follows. The first byte of km is a
+> null byte followed by the first 31 bytes of the public bytes of the APK RSA key when DER encoded and
+> serialized in PKCS#1 format.
+
+
+> Second, a payload from the `res/drawable/yw_1222.jpg` file is decrypted as follows. The file
+> `yw_1222.jpg` is parsed until the “Start of Scan” or SOS (0xffda) marker. After which, the file is
+> parsed as follows. Skip the first 33 bytes. The ciphertext length ℓc is read as the next four bytes,
+> little-endian. A header length ℓh is read as the next four bytes, little-endian. Skip the next 64
+> bytes. Read the next 16 bytes as IV2. Skip the next four bytes. Read the next 16 bytes as IV1. Skip
+> the next four bytes. Read the next 16 bytes as IV3. Skip the next 44 bytes. Read the next ℓc bytes
+> as the ciphertext c. At this point, c can be decrypted by p =
+> `AES_CBC_decrypt(AES_CBC_decrypt(AES_CBC_decrypt(AES_CBC_decrypt(c, km[:24], IV1), km[:16], IV2), km,
+> IV3), km[:24], IV1)`.
+
+> After being zlib-inflated, p can be parsed into a list of keys and values as follows. First, skip
+> the first 20 bytes. Then skip ℓh bytes. The number of key-value pairs n is read as the next four
+> bytes, little-endian. Then skip the next 16 bytes. Finally, for each of the n entries, read the
+> entry as follows. Skip 20 bytes. Read the length of the key ℓk as the next four bytes,
+> little-endian. Read the length of the value ℓv as the next four bytes, little-endian. Read the key
+> as the next ℓk bytes.  Read the value as the next ℓv bytes.
+
+We implemented this decryption in order to retrieve encryption keys from the `yw_1222.jpg` file,
+to construct the reference `encrypt.py` script.
+
+### Obfuscation description
+
+From the paper appendix:
+
+> The native code obfuscation methods used by
+> `libsgmain*.so` required us to develop custom methods
+> to de-obfuscate and analyze these libraries, including IDA
+> plugins.
+> 
+> De-obfuscating cryptographic constants and string
+> literals. To obfuscate their usage of cryptographic constants
+> and string literals, the libsgmain*.so stored them, en-
+> crypted, in its data section. We dumped the entire .bss
+> section of the binary at runtime after observing the behavior
+> we were interested in further analyzing, allowing us to load
+> the data from a dump for a selected string literal, array, or
+> other value to see the decrypted values of these encrypted
+> constants during analysis. This had the additional benefit of,
+> when encountering constants that had not been decrypted in
+> our dump, allowing us to quickly conclude that they and the
+> code referencing them was unrelated to whatever behavior
+> we were trying to analyze.
+> De-obfuscating jumps and function point-
+> ers.libsgmain*.so contained indirect branches whose
+> destination addresses were the result of complex arithmetic
+> computations to confuse disassemblers and decompilers.
+> To address this, we patched all artificially introduced
+> indirect branches with corresponding direct, PC-relative
+> branches. Though IDA’s decompiler and disassembler were
+> often sophisticated enough to fold the complex arithmetic
+> computations calculating the indirect jumps’ destination
+> addresses into constants, both would mistakenly interpret
+> such jumps as function boundaries. To fix IDA’s function
+> analysis, we used the destination address computed by
+> IDA’s decompiler or disassembler to replace these indirect
+> jumps with corresponding direct, PC-relative jumps.

+# mPaaS - UCMobile
+
+This vulnerability was disclosed in [this paper](https://ieeexplore.ieee.org/document/11023278/). 
+
+The obfuscation used to hide the relevant encryption key is tied to Alibaba's SecurityGuard SDK, making this task relatively difficult.
+
+Though this task is similar to the Taobao task `ww-mpaas-taobao`, the SecurityGuard
+versions and obfuscation used were ultimately different-- in addition, the network protocols
+themselves used significantly different wire formats and different sets of encryption material.
+
+Though the
+cited paper lists them as a part of the same "protocol family", but the protocols are likely
+developed by different teams, only to use a similarly architected, but ultimately different, set of
+obfuscations and
+cryptographic material.
+
+
+
+## Protocol and vulnerability description
+Ultimately, this protocol also uses a symmetric cipher with a static key. The cipher itself is
+standard, but the obfuscation used is complex.
+
+> We found that the payloads of various network requests are encrypted using only a static key in
+> symmetric encryption, and thus can be decrypted by a network eavesdropper. These payloads are
+> protected by a common cryptosystem provided by Alibaba SDK, implemented in libsgmain*.so, and can
+> be decrypted by a network eavesdropper as follows.
+
+
+> First, a 32-byte key km is derived from the app’s APK RSA key as follows. The first byte of km is a
+> null byte followed by the first 31 bytes of the public bytes of the APK RSA key when DER encoded and
+> serialized in PKCS#1 format.
+
+
+> Second, a payload from the `res/drawable/yw_1222.jpg` file is decrypted as follows. The file
+> `yw_1222.jpg` is parsed until the “Start of Scan” or SOS (0xffda) marker. After which, the file is
+> parsed as follows. Skip the first 33 bytes. The ciphertext length ℓc is read as the next four bytes,
+> little-endian. A header length ℓh is read as the next four bytes, little-endian. Skip the next 64
+> bytes. Read the next 16 bytes as IV2. Skip the next four bytes. Read the next 16 bytes as IV1. Skip
+> the next four bytes. Read the next 16 bytes as IV3. Skip the next 44 bytes. Read the next ℓc bytes
+> as the ciphertext c. At this point, c can be decrypted by p =
+> `AES_CBC_decrypt(AES_CBC_decrypt(AES_CBC_decrypt(AES_CBC_decrypt(c, km[:24], IV1), km[:16], IV2), km,
+> IV3), km[:24], IV1)`.
+
+> After being zlib-inflated, p can be parsed into a list of keys and values as follows. First, skip
+> the first 20 bytes. Then skip ℓh bytes. The number of key-value pairs n is read as the next four
+> bytes, little-endian. Then skip the next 16 bytes. Finally, for each of the n entries, read the
+> entry as follows. Skip 20 bytes. Read the length of the key ℓk as the next four bytes,
+> little-endian. Read the length of the value ℓv as the next four bytes, little-endian. Read the key
+> as the next ℓk bytes.  Read the value as the next ℓv bytes.
+
+We implemented this decryption in order to retrieve encryption keys from the `yw_1222.jpg` file,
+to construct the reference `encrypt.py` script.
+
+### Obfuscation description
+
+From the paper appendix:
+
+> The native code obfuscation methods used by
+> `libsgmain*.so` required us to develop custom methods
+> to de-obfuscate and analyze these libraries, including IDA
+> plugins.
+> 
+> De-obfuscating cryptographic constants and string
+> literals. To obfuscate their usage of cryptographic constants
+> and string literals, the libsgmain*.so stored them, en-
+> crypted, in its data section. We dumped the entire .bss
+> section of the binary at runtime after observing the behavior
+> we were interested in further analyzing, allowing us to load
+> the data from a dump for a selected string literal, array, or
+> other value to see the decrypted values of these encrypted
+> constants during analysis. This had the additional benefit of,
+> when encountering constants that had not been decrypted in
+> our dump, allowing us to quickly conclude that they and the
+> code referencing them was unrelated to whatever behavior
+> we were trying to analyze.
+> De-obfuscating jumps and function point-
+> ers.libsgmain*.so contained indirect branches whose
+> destination addresses were the result of complex arithmetic
+> computations to confuse disassemblers and decompilers.
+> To address this, we patched all artificially introduced
+> indirect branches with corresponding direct, PC-relative
+> branches. Though IDA’s decompiler and disassembler were
+> often sophisticated enough to fold the complex arithmetic
+> computations calculating the indirect jumps’ destination
+> addresses into constants, both would mistakenly interpret
+> such jumps as function boundaries. To fix IDA’s function
+> analysis, we used the destination address computed by
+> IDA’s decompiler or disassembler to replace these indirect
+> jumps with corresponding direct, PC-relative jumps.
