Verdict: Malicious activity
Threats:

The Arechclient2 malware is a sophisticated .NET-based Remote Access Trojan (RAT) that collects sensitive information, such as browser credentials, from infected computers. It employs various stealth techniques, including Base64 encoding to obscure its code and the ability to pause activities to evade automated security tools. The malware also can adjust Windows Defender settings and uses code injection to manipulate legitimate processes.
