What is Behavior:Win32/Rugmigen.B

Behavior:Win32/Rugmigen.B is a detection name utilized by Windows Defender to identify suspicious activities indicative of malware presence, particularly associated with the Rugmi malware family. This detection targets behavioral patterns rather than specific file signatures, allowing it to identify threats based on activities like unauthorized system modifications or attempts to disable security software. Rugmi, the malware behind this detection, acts primarily as a Trojan downloader, delivering other malicious payloads like infostealers that can compromise sensitive data, including login credentials and financial information. Its sophisticated structure comprises components such as a downloader, internal loader, and external loader, enabling it to execute payloads stealthily. Distribution of this malware occurs through vectors like malvertising, fake software updates, and compromised applications, with recent spikes indicating active campaigns exploiting these methods. The impact of Rugmi variants is significant, posing risks of data theft, system compromise, and performance degradation due to activities like cryptomining. Users are advised to employ reputable antivirus solutions, maintain up-to-date software, and practice cautious internet habits to mitigate the risk of infections associated with Behavior:Win32/Rugmigen.B.

How Behavior:Win32/Rugmigen.B infected your system
