Executive Summary Following disclosure of the TraderTraitor attack against LayerZero in April 2026, SentinelOne identified an additional victim with the same macOS backdoors. Our analysis explores the mechanics of these backdoors and the expanded targeting against a victim in the IT services sector with no relationship to cryptocurrency trading. We also identified more weaponized GitHub repositories from the social engineering schemes used to target job seekers in these campaigns. This report…
Researchers at Zimperium’s zLabs have analyzed an Android Trojan that uses an automated, multi-stage infection process. What’s new is that RatHat gives a live AI assistant the keys to the accessibility tree of the infected device and uses it to determine where to tap or scroll, rather than following a hardcoded script. The variable attack path makes it harder for signature- and rule-based mobile security tools to detect this Trojan. It also abuses Android Debug Bridge (ADB), a legitimate tool…

Brevo confirmed that attackers stole a Cloudflare API key and used it to inject malicious ClickFix scripts into its websites and JavaScript files embedded on customer sites to distribute malware. [...]
AI has already made fundamental changes to the operating environment for cybersecurity. Cyberattackers are testing more paths, adapting their techniques, and moving across digital environments with greater speed and persistence. The weaknesses they exploit remain familiar: excessive permissions, unprotected authentication flows, unpatched systems, exposed execution paths, and gaps between controls. What has changed is how quickly these weaknesses can combine into attack paths that cross…
Questo CSIRT ha recentemente registrato, nel contesto nazionale, un aumento significativo di sfruttamenti attivi della CVE-2026-48907 – già sanata dal vendor e trattata nell’ambito dell’AL02/260615/CSIRT-ITA – ai danni di server web esposti. Tale vulnerabilità interessa il plugin Joomla Content Editor (JCE), estensione per il noto Content Management System (CMS) Joomla!.
At the end of August, a malspam message was caught in the quarantine of a mail gateway operated by one of my customers. The message was not especially remarkable – it asked the recipient to review some attached requirements and provide a price quotation for a fiber optic system and appeared to impersonate an employee of a legitimate company. The receiving gateway quarantined the message because it detected malicious content in the attachment, though even if it didn’t, the e-mail would not have…
Introduction Torrent trackers have long been abused for distributing malicious software, disguised as popular films, games, and other content. Our previous research has shown that cybercriminals repeatedly turn torrents as an initial infection vector, using trojanized cracks and installers to reach a large number of users. Installation guides for pirated software routinely instruct users to disable their antivirus, conditioning them to ignore potential threats they are inviting onto their…

Over the past year, our Global Emergency Response Team (GERT) has investigated several incidents involving the NightEagle group (APT-Q-95). This group has been active since at least 2023 and originally focused on organizations in Asia, as we reported previously. We have now identified attacks by the group targeting businesses in Russia. This post examines both known and new tools NightEagle used in its latest campaign. Initial access In most incidents, the attackers used compromised valid…

China's spy chief identified Anthropic’s Claude Mythos and OpenAI’s GPT-5.5-Cyber as signs of what he called a “disruptive upgrade” in cyber capabilities, increasing the speed and potential weaponization of vulnerability discovery and malware development.
Researchers at Hudson Rock found that cybercriminals hijacked HBO Max’s verified Reddit account and used it to run 108 malicious ads over roughly 48 hours. The ads used HBO Max’s trusted corporate account to promote fake AI tools, developer software, and macOS utilities, lowering potential victims’ guards. Some ads directed users to convincing HBO lookalike sites that claimed to offer a native HBO Max app for macOS or a promotional download. But instead of providing an installer, the sites…

Elastic Security Labs has tracked REF9334, a Brazilian banking malware operation, since May 2025. Its toolkit is called KREMLIN (as named by the malware author, Kr3mlin4rt1st), though nothing about the operation is Russian. Lures impersonate twelve Brazilian banks; error messages and code comments are written in Portuguese, and the operators' Ethereum transactions cluster during São Paulo working hours. Over 15 months and seven campaigns, they built a malicious browser extension that installs…

Researchers at Group-IB found that the Android banking Trojan Gigabud can create a separate work profile on an infected phone and run a cloned banking app inside it. The attacker can then carry out fraudulent transactions in the new profile, potentially separating them from signs of malware detected elsewhere on the device. To do this, Gigabud installs Vwork, a malicious version of the legitimate open-source tool Shelter. Shelter normally lets Android users isolate apps or run second copies of…

Welcome to this week’s edition of the Threat Source newsletter. Ask anybody in this industry what the work does to the health of the people who do it and you get one word back: burnout. It's a fine word, in and of itself. It’s easy to reach for, understandable to everyone… and it's the wrong one, most of the time. So, story time. Last year I gave an interview with the amazing Hazel Burton about VPNFilter, and my run-in with burnout. I was a manager during that time, and it took a toll on me and…
Every wave of technology excitement creates a new opportunity for cyberattackers, and AI is no exception. Microsoft Threat Intelligence has published research showing a growing set of campaigns that impersonate popular AI platforms and tools, including ChatGPT, Microsoft Copilot, DeepSeek, and Claude.1 The goal is to make phishing, search-driven malware campaigns, and malvertising—which is malicious advertising that uses online ads to lure users to harmful sites, downloads, or redirect…
BlueMoon, a shared Chrome and Windows exploit kit, shows why “patch later” is becoming a dangerous gamble. Security updates are easy to put off. The browser still opens, Windows still works, and choosing to relaunch your browser or restart your computer later can feel harmless. But a newly documented exploit kit called “BlueMoon” shows how quickly patching delays can become dangerous. Proofpoint Researchers found four espionage groups using the same exploit chain against Chrome browsers running…
Multiple cyber-espionage groups deployed an exploit kit dubbed "BlueMoon" that leveraged zero-day vulnerabilities in Microsoft Windows and Google Chrome. [...]
[This is a Guest Diary by Aaron Ng, an ISC intern as part of the SANS.edu BACS program] Following a RedTail Linux Payload from DShield to Dynamic Analysis During monitoring of my DShield honeypot, I observed an attacker uploading a collection of Linux executables targeting several processor architectures. The files included ARM, ARM64, i686, RISC-V and x86-64 variants named as part of a RedTail deployment package. Rather than relying only on static indicators or public threat-intelligence…

Executive Summary Since the release of our May 2026 report detailing adversarial misuse of artificial intelligence (AI), Google Threat Intelligence Group (GTIG) has observed forward leaning adversaries transition from basic prompting to agentic AI workflows and AI-enabled automation. In these operations, human-in-the-loop latency is dramatically reduced, compressing the traditional window for defenders to respond. In Q2 2026, GTIG observed threat actors compromise a cloud resource, then plan,…
Cisco Talos began an investigation after observing a DLL named "verification.google" executing from WebDAV at a Ukrainian government organization. We assess with moderate confidence that the attacks are not targeted at a particular organization, but are a part of a cryptocurrency and credentials-stealing operation using the Amatera stealer as the primary payload. Pivoting around the similar WebDAV behavior led to a second loader named "pf.ch" and allowed us to reconstruct its earlier delivery…
Cisco Talos is tracking a cryptocurrency-stealing campaign that abuses the Google Visualization API for command and control (C2), retrieving obfuscated JavaScript from a publicly published Google Sheets document and injecting it into the victim's browser session. The actors use a variation on ClickFix social engineering. Instead of convincing targets to run commands against the operating system, they convince targets to paste JavaScript into the Chrome address bar or install it into the…
