| Verdict: | Malicious activity |
| Threats: | First identified in March 2021, PureCrypter is a .NET-based loader that employs obfuscation techniques, such as SmartAssembly, to evade detection. It has been used to distribute malware families including AgentTesla, RedLine Stealer, and SnakeKeylogger. The malware is typically delivered through phishing campaigns and malicious downloads, often masquerading as legitimate files with extensions like .mp4 or .pdf. PureCrypter utilizes encryption and compression to conceal its payloads and can inject malicious code into legitimate processes to maintain persistence on the infected system. |
