macOS Tahoe 26.4 blocks ClickFix paste attacks in Terminal - update your Mac fleet now

Apple shipped an undocumented security feature in macOS Tahoe 26.4 that directly targets ClickFix attacks - the social engineering technique behind the Infinity Stealer campaign we covered last week. When a user tries to paste a potentially harmful command into Terminal, macOS now intercepts it with a warning before anything executes. The feature only covers Apple's built-in Terminal app, not third-party alternatives like iTerm2. A 'Paste Anyway' option remains for power users.

Check
Check if your Mac fleet is running macOS Tahoe 26.4 or later.
Affected
Any macOS user on versions prior to 26.4 who may encounter ClickFix social engineering attacks via fake CAPTCHA pages or tech support sites.
Fix
Update to macOS Tahoe 26.4. Push the update via MDM for managed fleets. Train staff to never paste commands from websites into Terminal regardless of the prompt - the protection only covers Terminal.app, not third-party terminals.

New Infinity Stealer malware targets macOS through fake Cloudflare CAPTCHA pages

A new macOS infostealer called Infinity Stealer tricks users through fake Cloudflare CAPTCHA pages - a technique called ClickFix. Victims paste a command into Terminal thinking they're verifying their identity, but it silently installs malware. The payload is compiled with Nuitka - turning Python into native macOS binaries that are much harder for security tools to detect. It steals browser credentials, Keychain data, and crypto wallets.

Check
Alert your team - especially Mac users - to never paste unknown commands into Terminal from websites.
Affected
Any macOS user who encounters a Cloudflare-style CAPTCHA asking them to open Terminal.
Fix
Train staff to recognize fake CAPTCHA pages. Block the domain update-check[.]com. Run endpoint detection on macOS devices.

Fake VS Code security alerts flooding GitHub Discussions to spread malware

Thousands of fake Visual Studio Code vulnerability warnings are being posted across GitHub Discussions in automated waves - all from freshly created accounts. The posts use realistic titles like 'Severe Vulnerability - Immediate Update Required' with fabricated CVE IDs to pressure developers into downloading malware from Google Drive links. The payloads fingerprint victims before delivering secondary attacks, acting as a traffic distribution system.

Check
Warn your development team - never download VS Code updates from GitHub Discussion links or Google Drive.
Affected
Any developer using GitHub who encounters a VS Code security alert in Discussions with an external download link.
Fix
Only update VS Code through the built-in updater or code.visualstudio.com. Verify any CVE IDs against NVD or CISA KEV before acting on them.
