Research by: Amit Yardeni Key Points A Chinese-speaking actor is now targeting Brazil. Check Point Research has uncovered a sustained campaign against Brazilian organizations, primarily government and educational institutions since mid-2025. We dubbed this group Gambling Goblin: a Chinese-speaking cybercrime cluster connected to a previously documented group, Earth Berberoka, that targeted gambling sites across Asia. It marks a shift from Brazil’s usual home-grown banking-trojan threats to a…

Elastic Security Labs is tracking an emerging infostealer, REVSTEALER, under REF2859. This family has gained momentum in recent months, with higher distribution volume, and has emerged as a formidable threat, featuring a comprehensive credential harvester, an embedded sandbox scoring system, and a Polygon blockchain-based dead drop for resilience. Beyond credential theft, REVSTEALER targets gaming platforms for additional monetization; the developer clearly understands that victim accounts on…

We’ve seen scam sites built around Grand Theft Auto VI (GTA 6) targeting visitors in three different ways this year. In June, we looked at sites selling GTA 6 “early access” for hundreds of dollars in cryptocurrency. You paid, got nothing, and could not reverse the payment. In August, we found fake Extended Look and demo sites delivering an infostealer instead of a game. The site we examined this week looks like a GTA 6 fan countdown site but offers to sell a leaked copy of the game. It loads a…
In a report published Tuesday, Kaspersky said it first discovered NodeRabbit on a system in Afghanistan and later identified variants on systems in Egypt and Ethiopia.
Microsoft has published details about a Windows malware campaign it calls TerminalFix. The social engineering used to infect people is very similar to what we’ve seen in ClickFix campaigns. A website visitor is presented with a fake Cloudflare CAPTCHA which, when clicked, secretly copies a malicious command to their clipboard. Then they receive instructions on what they need to do to “prove they are human,” when in reality they are being instructed to execute the malicious command. After…
Anthropic has warned some Claude users that criminals are using information stealers to take over their accounts. Rather than guessing passwords or intercepting two-factor authentication (2FA) codes, the attackers steal the browser sessions that prove a user is already logged in. According to a warning email shared publicly by an affected user, the attackers used common infostealer malware to copy Claude login sessions from victims’ computers. They then used those sessions to access the…
While monitoring Mirage Kitten activity, we uncovered a previously undocumented malware family that we dubbed NodeRabbit. We identified the first sample on a system in Afghanistan. Further threat hunting revealed two additional, more advanced, variants: one on a system in Egypt and another on a system in Ethiopia. NodeRabbit is a cross-platform remote access trojan (RAT) built with Node.js. It targets Windows, Linux, and macOS. Its operators deliver it through spear-phishing messages on…

Classification: Severe, Solution: Official Fix, Exploit Maturity: Proof-of-Concept, CVSSv3.1: 9.8, CVEs: CVE-2026-61979, CVE-2026-15981, Summary: The two vulnerabilities observed in exploitation attempts are tracked as CVE-2026-61979 and CVE-2026-15981 and can be chained together to bypass authentication. Because the miniOrange SAML SSO plugin accepts the signature algorithm from incoming SAML responses instead of enforcing the configured one, an attacker can leverage CVE-2026-61979 to select…

Researchers at Group-IB have discovered a new NFC relay malware family, purpose-built to capture live card data via NFC and forward it in real time to attackers. They dubbed it “WindRelay.” NFC (Near Field Communication) is wireless technology that allows devices such as smartphones, payment cards, and payment terminals to communicate when they’re very close together. So, instead of stealing your physical bank card, the attackers capture NFC activity on an infected mobile phone and relay it in…
Cisco Talos recently identified an undocumented phishing framework, internally branded "JWR" by its developer, built to convincingly impersonate checkout and login pages across major payment and shopping platforms. The client engine of the JWR phishing framework is a real-time, operator-driven system that, rather than merely logging form submissions like a static credential-stealing page, keeps an AES-CTR encrypted WebSocket open to the threat actor so they can steer each victim's session live.…
