activate interprets libcerberus.so as bytecode for a custom vm with an mmu. traced it via ptrace, reversed the opcode set and the seeded rolling hash check, key fell out of the recurrence |

Password HVUHADN — recovered by cross-referencing the result strings and disassembling the check at 0x100fd: the password is stored as two overlapping 4-byte XOR constants (0x48555648 'HVUH' + 0x4e444 |

Name is hashed with 32-bit FNV-1a plus two rotating accumulators, then fmix32-avalanched; "%08x%08x%08x" gives the 24-char sigil. ptrace(TRACEME) anti-debug only; trivial forward keygen. |
