Hackers hijack HBO Max Reddit account to push malware in ClickFix ads

Hackers hijacked HBO Max's verified Reddit account to run 108 ClickFix ads delivering infostealers and crypto clippers to Windows and macOS users.

Hudson Rock and ADAMnetworks linked the hijacked u/hbomax Reddit account to a campaign they call PasteSwitch, which ran 108 malicious ads over roughly 48 hours pushing sites like hbomaxx.us, codex-craft.com, and code-desktop.com. ClickFix social engineering tricks victims into pasting Base64-obfuscated shell or PowerShell commands into Terminal or Run, delivering MacSync, AMOS helper persistence, Amatera Stealer loaded in-memory, and the AnimateClipper and ZigClipper crypto clipboard hijackers. Windows chains used an MP3/HTA polyglot to create scheduled tasks, disable AMSI, and launch 32-bit PowerShell; fake Ledger, Trezor Suite, and Exodus wallet apps steal recovery phrases. Reddit admins paused the ads, and it remains unclear how the account was accessed.

Pro-Ukraine Hacking Cat group deploying new malware against Russian targets

Kaspersky links pro-Ukraine hacktivist group Hacking Cat to Gorilla RAT and Monkey Ransomware in destructive attacks on Russian targets.

Kaspersky reports that pro-Ukraine group Hacking Cat, active since February 2024, has shifted from defacements to destructive encryption attacks, using a previously undocumented Gorilla RAT remote-access tool and Monkey Ransomware, which appends the .monkey extension to files. Initial access in some attacks came from exploited Microsoft Exchange vulnerabilities, and rapid multi-language malware variants suggest possible generative AI assistance. Shared tools like Nemo Wiper across groups including Ukrainian Cyber Alliance complicate attribution, and targets include Rosatom contractor and heating provider Donbassteploenergo.

Hackers Use Fake LinkedIn Job Offers to Infect Developers With New Cross-Platform RATs

Iran-linked Mirage Kitten uses fake LinkedIn job challenges to deliver new cross-platform RATs NodeRabbit and PollCat to developers in fintech, aviation, and aerospace.

PolySwarm documented a campaign by Iran-linked Mirage Kitten (UNC1549) that uses fake recruiter personas and technical hiring challenges on LinkedIn to deliver the newly documented RATs NodeRabbit and PollCat, which run on Windows, Linux, and macOS. A challenge archive bundles a fake npm package (colorized_terminal 2.1.0) in node_modules that loads NodeRabbit, while a React-based challenge delivers PollCat with an attacker-controlled OTP screen. NodeRabbit persists through a malicious Visual Studio Code extension and Git post-merge/post-checkout hooks; PollCat persists via scheduled tasks, cron, and LaunchAgents. Victims were observed in fintech, aviation, and aerospace, with confirmed targets in Egypt, Ethiopia, and Afghanistan.

AmnesiaStealer Gives Attackers Live Control of Victims’ macOS Browsers

Jamf Threat Labs analyzed AmnesiaStealer, a Rust-based macOS infostealer spread via fake GitHub pages that also grants live hidden browser control.

AmnesiaStealer is a three-stage Rust infostealer distributed through counterfeit GitHub download pages using the ClickFix technique, a lure shared with Atomic Stealer and MacSync campaigns. It harvests the keychain, 16 Chromium browsers, Apple Notes, Telegram and documents, reusing a password captured via a fake installer dialog. A third-stage stream module clones the victim's browser profile headlessly and lets operators drive the session via Chrome DevTools Protocol, while persistence uses a LaunchDaemon impersonating Apple's com.apple.ReportCrash.agent. On macOS 26 it may replace Chrome's Safe Storage key, a useful detection signal.

ClickFix attacks are tricking Mac and Windows users into hacking themselves

ClickFix campaigns trick users into pasting terminal commands via fake CAPTCHAs; latest wave abused HBO Max's hacked Reddit account to push infostealer ads.

ClickFix attacks use fake CAPTCHA or anti-bot prompts on hacked or counterfeit websites to convince victims to copy a command into Windows Command Prompt or macOS Terminal, instantly installing infostealers that steal passwords, logged-in sessions, and crypto wallets. The latest campaign compromised HBO Max's official Reddit account to post hundreds of fake ads linking to a spoofed HBO Max page carrying the lure, per researchers at Hudson Rock. It is unclear how many users were compromised. Because execution happens in the terminal, many attacks evade antivirus tools; enterprises can block terminals domain-wide and Mac users can deploy BlockBlock.

Iran-linked APT Mirage Kitten Uses Fake Job Tests to Spread Malware

Kaspersky reports Iran-linked Mirage Kitten delivers new NodeRabbit and PollCat malware to fintech and aviation targets via fake LinkedIn coding assessments.

Kaspersky researchers documented two previously undocumented Node.js malware families, NodeRabbit and PollCat, attributed with high confidence to Iran-linked APT group Mirage Kitten. The malware is delivered via fake recruiter personas on LinkedIn offering coding assessments hosted on Amazon S3, with instructions banning AI assistants so AI code-review tools would not flag the trojanized npm packages. NodeRabbit is cross-platform (Windows, Linux, macOS), uses AES-256-GCM-encrypted C2 on Azure, includes sandbox checks, and one variant installs a fake 'GitHub Copilot Helper' VS Code extension plus Git hook persistence. Victims identified so far are in fintech and aviation organizations across Egypt, Ethiopia, and Afghanistan.

Fake OpenAI Codex download tricks macOS users into installing malware

Cato Networks uncovered a malware campaign using sponsored search ads and fake OpenAI Codex pages to deliver an AMOS-like infostealer to macOS users.

Cato Networks researchers discovered a campaign using sponsored search results and a fake OpenAI Codex download portal on Google Sites to lure macOS users. Victims are instructed to paste a Terminal command that decodes a Base64-encoded URL and runs a multi-stage infection chain ending in a universal Mach-O binary. The delivery chain closely resembles Atomic macOS Stealer (AMOS), and related infrastructure impersonating Claude Code was also found. Operators use iframe-based hosting and path/device gating to evade analysts and automated scanners.

Hackers Target Claude, Cursor and Codex AI Agents to Steal Tokens and Prompt Histories

Gen Digital found infostealers like Amatera and Remus stealing AI coding agent tokens, prompt histories, and MCP configs from infected Windows and macOS machines.

Gen Digital analysts observed Amatera and Remus detections among tens of thousands of protected Windows users over three months, with Amatera targeting Cline and Continue data and Remus targeting Claude, Cursor, and OpenCode. CallbackBeaver added Cursor and Claude to its collection scope with more than 5,000 samples in 30 days, while macOS-focused Djinn Stealer has been associated with Claude, Codex, Gemini, Cline, OpenCode, and Kilo. The stealers harvest access and refresh tokens, prompt histories, and MCP configuration files that can expose source control, ticketing, databases, cloud resources, and sensitive project context for follow-on fraud. Many stealers add targets via remotely managed rules, meaning this is an adaptation of existing infostealers rather than a new vulnerability in the AI tools themselves.

The Hidden Instructions That Can Hijack AI Agents

Hidden prompt injections embedded in documents and metadata can hijack autonomous AI agents, causing data exfiltration and out-of-policy actions at machine speed.

Bowbridge warns that hidden indirect prompt injections, embedded in documents, metadata, emails, images, and code repositories, can cause autonomous AI agents to treat attacker-controlled content as trusted guidance. Because agents inherit user privileges, act silently, and lack human judgment, injections can lead to data exfiltration or file poisoning that traditional security controls cannot detect. A real-world example involved a supplier quote whose metadata instructed an agent to override guidance and select the most expensive option. Bowbridge recommends scanning documents before agents process them.
