GhostPoster Malware: Firefox Add-ons Go Full Dumpster Fire

Well, fuck me sideways with a broken CAT5 cable — turns out that a bunch of so-called “useful” Firefox add-ons were actually moonlighting as nosy little bastards. Seventeen of these digital turds, collectively downloaded over 50,000 times, were found infected with the oh-so-cleverly named GhostPoster malware. Because of course, the one goddamn time you trust a plugin to do something simple — block ads, customize a theme, bake cookies or whatever — it decides to start exfiltrating your data like a kleptomaniac AI on meth.

The geniuses behind this malcode apparently thought it was cute to use the add-ons for sneaky data harvesting, tracking, and remote command shenanigans. They embedded scripts that could send stolen details to command servers, modify browser behavior, and basically make your life more miserable than a Windows registry after a malware party. Mozilla yanked the infected crap faster than a caffeine-fueled sysadmin pulling a network cable from an intern’s “experiment,” but if you were one of the poor bastards who installed them, congratulations — you might’ve just given the GhostPoster goons a front-row seat to your browser history of shame.

The moral of the story? Stop trusting random add-ons made by shady developers with usernames like “CoolAddonDev1337.” And for the love of all things silicon, maybe check the goddamn permissions before installing something that wants access to everything from your browsing history to your blood type.

Reminds me of the time some genius in accounting clicked on a “Free Invoice Generator” plugin and then wondered why our printers were spitting out ransom notes in Cyrillic. Ah, good times.
