Static C2 configuration recovery, 2026-10-25 UTC. SHA-256 verified; complete 67,952-byte x86-64 ELF, upstream first_seen 2026-10-25 06:16:31 UTC. Table entry 1 copies 24 encrypted bytes from file offset 0xe939. The unlock routine at 0x407990 applies all four bytes of the table key; their combined XOR is 0x04, recovering ditcumaybandi.devs.surf plus terminator. Resolver callback 0x4067a0 unlocks/retrieves entry 1, resolves it through 0x4073a0, selects an IPv4 result and writes sockaddr.sin_addr at 0x4067f1. At 0x4067fc it writes port halfword 0x6eb2: little-endian memory b2 6e gives network TCP port 45678. Main installs this resolver callback at 0x4068ad and invokes it before connect at 0x406e70; connect wrapper 0x40a100 issues x86-64 syscall 42. Google and Cloudflare public DNS both returned 150.40.98.5 during review. This is time-specific compiled/DNS configuration, not an observed live bot session. Initial address 217.32.184.17:23 is separately initialized before the callback; it was not submitted as the resolved endpoint. ELF section table ends exactly at EOF and allocated sections agree with PT_LOAD mappings. Attack and command-handling code is consistent with Mirai lineage. Search-engine/referrer strings, protocol payload addresses and public DNS services are not additional C2 IOCs. No execution or C2 connection.
