CISA Waves the Bloody Red Flag Over a ScreenConnect Flaw

Right, here’s the short version before some genius ignores it and gets ransomwared into next week. CISA has flagged an actively exploited vulnerability in ConnectWise ScreenConnect, which means the usual pack of opportunistic bastards are already hammering away at it in the wild. This isn’t some theoretical “maybe one day” security issue for a committee to discuss over stale biscuits. It’s being exploited now, you poor unlucky sods.

The article points out that the flaw affects ScreenConnect, the remote access tool that plenty of admins and MSPs use because apparently giving remote control software broad access to everything has never gone horribly wrong before. CISA added the vulnerability to its Known Exploited Vulnerabilities catalog, which is bureaucrat-speak for: “Patch this shit immediately before someone turns your network into a smoking crater.”

The vendor has issued fixes, and the advice is the same as always, though somehow still beyond the abilities of half the industry: update the bloody software, review exposed systems, and assume that if you’ve left this thing hanging open on the internet, some malicious little goblin has already had a poke at it. If you’re in charge of federal systems, there are deadlines. If you’re everyone else, the deadline is effectively before you get owned, which tends to be less negotiable.

The bigger lesson, in case anyone still needs it tattooed on their forehead, is that remote management and access tools are catnip for attackers. If there’s a hole in one of these platforms, criminals don’t sit around politely waiting for your maintenance window. They weaponize the damn thing and start cashing in while IT departments are still drafting meeting invites about “remediation strategy.”

So yes, patch immediately, verify your version, check logs for suspicious activity, and stop pretending that “we’ll get to it after the change board approves it” is a security strategy. It isn’t. It’s how you end up explaining to management why all the servers are encrypted and the backups are mysteriously fucked.

Anecdote time: years ago, I watched a smug admin ignore an urgent remote access patch because he didn’t want to interrupt a lunchtime webinar about “cyber resilience.” By the end of the day, his systems had all the resilience of wet toilet paper, and he was asking whether disconnected tape backups were still considered fashionable. They were. Funny how that works.
