supply chain attack
About this tag
A supply chain attack exploits trusted software update mechanisms to deliver malware, as seen in two notable incidents discussed on WindowsForum. In one case, Notepad++ users were targeted between June and December 2025 when attackers intercepted update traffic to deliver the Chrysalis backdoor, gaining remote access to systems. In another, MicroWorld eScan antivirus was compromised in January 2026 when a threat actor breached a regional update server and pushed a trojanized update for two hours, turning the security tool into a backdoor. These attacks highlight the vulnerability of software update infrastructure and the need for vigilance in verifying update integrity, especially for Windows applications and enterprise environments.
