You need to login to in order to write a comment. Login with your abuse.ch account.Linux x86-64 backdoor. Static, stripped, not packed. No family name: it matches
nothing I could find. Found on an internet-facing host after compromise.
C2 is DTLS over UDP, built on mbedTLS. The DTLS code is complete: reassembly,
epochs, retransmission, HelloVerifyRequest cookies. Client and server state
machines are both present and it calls bind(), so it can listen as well as
beacon. It verifies the peer certificate. It also speaks HTTP.
Capabilities: shell (/bin/sh via fork/execve with pipes), full file read/write
and delete, directory listing (getdents64), setuid/setgid, setsid daemonising,
kill, setrlimit and scheduler control, and mprotect. Interactive access, not a
bot.
Anti-debug: reads /proc/self/status and checks TracerPid twice. It never calls
ptrace, so ptrace-based bypasses do not apply.
Strings are obfuscated with repeating-key XOR at 0x402f9d (buf[i] ^= key[i %
strlen(key)]). Two 64-byte ASCII keys, which should work on sibling samples:
0x455950 &s7xNXr97qNg8fAA]Q#J1eSmXvwS!A]nvRBtwB;.frq<pUN>s9SVuR)Qn**km0e
0x455970 vRBtwB;.frq<pUN>s9SVuR)Qn**km0e;B??$7h89Ew6Z<pb&[7G!m9@dR?4rj5D
The C2 address is not in the file, in any encoding I could find. Config is
decrypted at runtime from a dropped file or the first packet.
