Therefore, we can hijack the DLL and execute our own code to intercept and terminate the malware. Leverage RansomLordNG v1.0 for DLL generation, while written as a proof-of-concept to specifically defeat ransomware, these DLLs may also defeat other types of malware if vulnerable. All basic tests were conducted successfully in a virtual machine environment. RansomLordNG v1.0 currently includes enhanced logging, memory dump and deweaponize features. Family: Poison Type: PE32 Attack-pattern TTP: Hijack Execution Flow (T1574) MD5: b2e50fa38510a5ea8e11f614b1c1d0d5 SHA256: 0de336f07cc19a6fda4cf9dacf1c4be0c6fb17158182d5274355cffa494ac8ed Vuln ID: MVID-2025-0701 Disclosure: 12/20/2025 Exploit/PoC: 1) Download RansomLordNG v1.0 https://github.com/malvuln/RansomLord 2) Locate the x32 WININET.dll entry using the -m flag (DLL Map) 3) Use -g flag (Generate Exploit) to output an DLL, based on an existing vulnerable malware in the victims list. 4) (Optional) -e flag to setup Windows event IOC logging in the registry, this will log the SHA256 hash, full path and filename.
