On May 14, 2026, a supply chain attack was discovered targeting the Okendo Reviews widget, a customer review platform used by over 18,000 brands. The threat actor injected malicious JavaScript code into the legitimate widget, which is deployed on high-traffic e-commerce pages including storefronts and product pages. The compromised JavaScript acted as a staged loader, using obfuscation, localStorage tracking, User-Agent filtering, and XOR-based decoding to conceal next-stage infrastructure. The attack employed ClickFix-style social engineering to deceive users into executing malicious commands, ultimately delivering remote access trojans like NetSupport and Remcos, or information stealers such as StealC. Affected websites received hundreds of thousands to millions of monthly visitors, with nearly 15,000 blocks recorded in a single day.
In March 2026, threat actors leveraged AI-powered website builders to create typosquatting domains impersonating a Brazilian bank. The campaign employed ClickFix techniques, presenting victims with fake CAPTCHA and BSOD screens to trick them into executing malicious PowerShell commands. This delivered SmartRAT, a PowerShell-based banking trojan with capabilities including encrypted C2 communications, remote control of screen/keyboard/mouse, credential theft through keylogging and banking overlays, and QR code interception for transaction fraud. The malware establishes persistence via scheduled tasks and Windows services, and targets Brazilian financial institutions, payment platforms, and cryptocurrency exchanges. The threat actors' C2 panel contained critical authentication flaws allowing client-side bypass, suggesting deployment without adequate security review.
