Net-NTLMv2 hash disclosure via crafted scan file
Published Aug 5, 2025 · Updated Aug 5, 2025
Information disclosure in Emsisoft Anti-Malware before 2024.12 allows remote attackers to obtain Net-NTLMv2 hashes through a crafted A2S file. Published records identify the scanning module and custom-scan file format but do not disclose the A2S field or parsing operation that triggers credential exposure. Exploitation requires the scanning module to process the crafted file and contact an attacker-controlled remote server, exposing authentication material without reported integrity or availability impact.
