VectraRAT Malware-as-a-Service Lets Hackers Bypass UAC and Hijack Windows Systems
New VectraRAT malware-as-a-service at $250/month combines RAT capabilities, credential theft, clipboard hijacking, and a UACME-based UAC bypass; 38 victims observed.
VectraRAT is a previously undocumented MaaS platform with a Go-based VectraHub Linux C2 server embedding a Vue3 operator panel and a C++ Windows implant, rented from $250/month and linked to the aliases Vectra and Nyxel. It communicates over TCP port 3308 via a proprietary MessagePack protocol, steals browser and file-based credentials, and abuses UACME method 41 with debug-object handle hijacking via winver.exe and computerdefaults.exe. SOCRadar identified 38 live victim sessions in one week, 48% on corporate Windows editions, with delivery via the Amadey loader and ClickFix pages impersonating TurboTax.
Risky Bulletin: Expired cards can be used for new transactions
Researchers show expired Visa contactless cards can be revived via NFC man-in-the-middle relay to run fraudulent transactions; roundup also covers major breaches.
University of Massachusetts Amherst researchers built an NFC man-in-the-middle rig that updates a card's expiration date in transit and relays the modified payment to POS terminals, reviving expired contactless cards; Visa terminals and the backends of all five banks studied failed to catch the manipulation. The same roundup reports Iranian hackers shut down a small UK power plant for four days, Lazarus breached South Korea's Presidential Office as part of a campaign exceeding 100 victims, and French telecom SFR suffered a breach affecting over 2.1 million customers.
WindRelay Android Malware Turns Victims' Phones Into NFC Relays for Payment Fraud
Group-IB details WindRelay, a new Android NFC relay malware paired with SpyNote RAT to relay card data live for contactless payment fraud and loans.
Group-IB identified WindRelay, a previously unseen Android near-field-communication relay malware first seen in the wild in late August 2025, deployed alongside the SpyNote RAT in a contactless payment fraud scheme. Victims are lured via personalized phishing, smishing, or vishing into sideloading an app; SpyNote's Accessibility access silently installs WindRelay, whose reader component captures live EMV APDU card data over NFC and relays it via WebSocket C2 to an emulator component at a payment terminal. The scheme enables dual monetization: RAT-driven remote access to take out digital loans and NFC relay for physical card-present cashouts, known as Ghost Tap. Twenty-three WindRelay samples uploaded to VirusTotal between November 2025 and July 2026 impersonate financial institutions in Czechia, Slovakia, and Slovenia, with the technique also spreading to Brazil and Poland.
