Fake LastPass Authenticator GitHub Repos Spread New Rapuncel Infostealer
A campaign exploits SEO-optimized fake LastPass Authenticator GitHub repositories to distribute a new information stealer named Rapuncel.
Why it matters
The use of trusted-appearing GitHub repositories for malware delivery signals evolving threat techniques that may bypass standard security filters.
SOC impact
Detect and monitor GitHub repository activity involving fake LastPass Authenticator projects, investigate related download behavior, and identify systems where Rapuncel malware may be present.
Recommended actions
- Identify active GitHub repositories impersonating LastPass Authenticator
- Monitor endpoint telemetry for downloads related to Rapuncel infostealer
- Review alert data from threat intelligence for Rapuncel indicators
- Analyze user activity for interaction with suspicious repositories
- Assess security controls for detecting repository-based malware distribution
Executive Summary
Security researchers have identified a new campaign leveraging fake GitHub repositories that impersonate the LastPass Authenticator app to spread a previously unknown information stealer called Rapuncel. These repositories are SEO-optimized to appear in search results and target users looking for legitimate authentication software. By exploiting the trust users place in GitHub and recognized software brands, attackers increase the chances of infection.
Operationally, this development underscores the need for vigilance around software sourcing and repository validation within organizational environments. The introduction of Rapuncel through this novel attack vector may complicate detection efforts, requiring focused analysis of authentication-related downloads and repository accesses. Monitoring for indicators related to these fake repositories will help uncover potential compromises.
