In March 2026, cirosec identified an active malware campaign targeting developers, IT professionals, and power users who rely on popular open-source and productivity tools such as Joplin, PuTTY, WinSCP, KeePass, FileZilla, 7-Zip, and, more recently, Gemini CLI. The attackers cloned the official websites of these products, manipulated Bing search rankings to place their malicious copies above the legitimate results, and bundled a credential-stealer with genuine software installers. Because the real application is installed along with the malware, victims have little reason to suspect that anything went wrong.
