Malware already running on a Mac can quietly take over Meta's Muse assistant and use the broad access its owner granted the app, security researcher Patrick Wardle has shown in a proof-of-concept released on September 21. It works by changing a hidden setting so that when the user taps the microphone and dictates a prompt, the words go to the attacker instead of Meta. The flaw is in
A new flaw in WordPress core let an anonymous visitor leave a comment that planted a hidden script on the page.

WordPress fixed the flaw, tracked as CVE-2026-93485 and called "Comment2Shell," on September 17 in version 7.1.1 and told site owners to update right away. There is

Microsoft Security Research published an interesting blog post "TerminalFix campaign deploys a reverse tunnel through multistage intrusion" about a malware campaign. The aspect that I want to take a closer look at, is the fact that the threat actors used PNG files with steganography. I reached out to the researchers and they kindly shared the IOCs for the PNG files with me.
