Login with your abuse.ch account.Static analysis of archived ARM ELF with debug symbols, 2026-10-24; SHA-256 verified. resolve_cnc_addr at 0xf95c loads literal realsus.net at VA 0x1a264 and calls resolv_lookup. It unlocks table entry 2 and copies its 16-bit value to sockaddr port. table_init loads encrypted port bytes 4b c4 from VA 0x1a294. table_unlock_val at 0x10eb8 XORs each byte with all four bytes of table_key 0xdedefbaf, yielding effective key 0x54 and network-order port bytes 1f 90 (8080). Thus compiled configuration is realsus.net:8080. The resolver has a loopback fallback on failure, not a second malicious external C2. Symbols also include attack_parse_body and attack_method_backconnect. This is a September capture and does not establish current domain control, DNS resolution or ongoing activity; retained as historical intelligence and not resubmitted as a fresh IOC. No execution or endpoint connection.
