In a move that has sent shockwaves through the cybersecurity world and grandmothers baking cookies, a Linux malware has been on the loose, stealthily slipping through antivirus software like butter through warm toast. Those extra-long email chains with dubious RAR attachments insisting they’re Aunt Susan’s ‘top secret’ chocolate chip cookie recipe? Turns out, they’re top secret for entirely different reasons.

The malicious masterminds, who apparently have a recipe for disaster, skip the conventional ‘hide-in-the-file-content’ approach, opting instead for the cunning ‘straight-outta-RAR-filename’ trick. And just like that, antivirus software, which can spot a suspicious file a mile away, has been left befuddled, mistaking malevolence for mozzarella sticks.

Phishing emails delivering the VShell open-source backdoor aren’t just about stealing your data—they’re a nostalgia trip back to the early 2000s when unsolicited email attachments were like online treasure hunts. Except this time, the treasure is a folder full of compromised systems. Rest assured, somewhere a group of hackers is laughing, raising their glasses to the digital sleight of hand and wondering if they can get Grandma to knit them some malware-inspired socks.
