Malicious Chrome Extension FreeVPN-One Detection
This Logic detects the presence of the malicious Chrome extension FreeVPN[.]One by identifying its unique extension ID across installed browsers. The logic further correlates this presence with network communications initiated by the extension to suspicious or untrusted domains. By combining extension enumeration with traffic analysis, the detection ensures high fidelity with minimal false positives. This layered approach strengthens visibility into malicious browser add-ons masquerading as VPN tools.

Notepad++ supply chain attack
This query detects a state-sponsored supply chain attack where the legitimate Notepad++ updater (gup.exe) is hijacked to download the Chrysalis backdoor. It identifies the attack by spotting unauthorized network connections from the updater, malicious DLL side-loading (e.g., BluetoothService.exe loading log.dll), and data exfiltration commands involving curl and temp.sh. https://notepad-plus-plus.org/news/hijacked-incident-info-update/ https://notepad-plus-plus.org/news/clarification-security-incident/ https://securelist.com/notepad-supply-chain-attack/118708/ https://notepad-plus-plus.org/assets/data/IoCFromFormerHostingProvider.txt https://www.rapid7.com/blog/post/tr-chrysalis-backdoor-dive-into-lotus-blossoms-toolkit/
