Meta Ads Push StreamRat Android Trojan That Can Gain Near-Complete Device Control

ThreatFabric details StreamRat, a new Android banking trojan spread via Meta malvertising in Spain that reached about 571,000 EU accounts.

ThreatFabric reported that a fake TV-streaming malvertising campaign on Meta promoted StreamRat, a technically sophisticated Android banking trojan, targeting Spanish-speaking users; the ads reached an estimated 570,950 Meta accounts in the EU between June 11 and July 3, 2026. Once installed via sideloaded APKs, the trojan abuses Accessibility to log keystrokes, show credential-stealing overlays, capture screens, and remotely control devices, and was also promoted through TikTok. Its dropper requests default Home app and VPN permissions and was hosted via GitHub releases, closely resembling one used in the earlier Mirax campaign. C2 infrastructure includes IPs 45.147.28.59 and 193.32.2.245, and no named threat actor was attributed.

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.

ValleyRAT Backdoor Hides in Signed Adware That Users Add to Antivirus Exclusions

Silver Fox distributes ValleyRAT via signed QN Wallpaper adware, sideloading a malicious libcef.dll into a trusted process to evade defenses.

Kaspersky reports the Silver Fox threat actor disguising the ValleyRAT backdoor (Winos 4.0) inside a modified, signed copy of the QN Wallpaper adware tool, using DLL sideloading to run within a trusted process. The installer disables Windows Defender via the DisableAntiSpyware registry key, adds autorun entries, and elevates via runas when needed; ValleyRAT steals keystrokes, clipboard data, and screenshots and can mark its process critical to trigger BSOD if killed. Kaspersky recorded more than 100,000 ValleyRAT detections affecting over 1,500 unique users in 2026, mostly in China and India, with prior campaigns against Japan, India, and Russia.

BraZetsu Malware Turns Compromised Windows Hosts Into Criminal Marketplace Inventory

Group-IB details BraZetsu, a modular Python Windows malware that monetizes compromised-host access through the Infected Marketplace for initial access brokers.

Group-IB attributes BraZetsu to the Exilware threat actor, believed to be native Portuguese speakers targeting Iberian and Latin American e-commerce, financial, industrial, and law enforcement victims. The framework, first observed in early May 2026, uses generative AI for data triage and target prioritization, steals browser histories and digital certificates, and hunts Brazilian CNAB financial remittance files. Access to compromised hosts is sold on the Infected Marketplace from roughly $5.80, letting buyers remotely deploy secondary payloads over WebSocket-linked infrastructure. Some samples evaded detection on VirusTotal; delivery likely uses VBS loaders from a domain also used to distribute the Ousaban banking trojan.

ClearFake Deploys Crypto Stealer That Uses Vulnerable Driver to Kill EDR Security Tools

Cisco Talos details ClearFake's fake-CAPTCHA chain deploying ZigCryptoStealer with a BYOVD attack that kills EDR processes, observed at a Ukrainian government organization in April 2026.

ClearFake compromises websites, injects JavaScript via a malicious Cloudflare Worker, retrieves instructions from BNB Smart Chain contracts (EtherHiding), and presents a fake Google CAPTCHA that tricks Windows users into pasting a command that loads a remote library over WebDAV via rundll32. The crypto-stealer branch uses DLL side-loading with a signed Chrome component to launch ZigCryptoStealer, which hijacks clipboard cryptocurrency addresses, alongside a signed but vulnerable Windows driver used in a BYOVD attack to terminate EDR processes. A parallel branch delivers Amatera secondary payloads that install a hidden remote-access client providing operator desktop control, with Cisco Talos tracking the remote-loader activity as UAT-10820. Talos observed unusual remote library execution at a Ukrainian government organization in April 2026 and assesses the attacks are part of a broader theft operation rather than a single targeted campaign.
