14,500 Dahua Cameras Pwned in 35 Days Because Apparently Nobody Knows How to Patch Their Shit

Right then, here’s your daily reminder that the internet is absolutely crammed with insecure garbage. According to the report, attackers managed to compromise roughly 14,500 Dahua web cameras in just 35 days. Thirty-fucking-five. That’s not a sophisticated years-long espionage epic. That’s basically a long lunch break in cybercrime terms.

The campaign targeted exposed Dahua devices, hoovering up vulnerable internet-facing cameras like a drunk sysadmin grabbing free donuts from the break room. The attackers exploited a command injection flaw affecting specific Dahua camera models and used it to take over the devices remotely. Because of course they did. If you leave half-baked surveillance kit dangling on the public internet with exploitable bugs, some bastard is going to come along and press the big red “own this box” button.

The numbers are the part that should make even the most complacent IT manager spill their lukewarm coffee: over 14,500 compromised devices spread across multiple countries, all folded into a botnet operation at industrial scale. Not a one-off prank. Not some bored teenager in a basement. A proper, automated, mass-compromise campaign, because lazy defenders make life beautifully efficient for assholes.

Researchers said the attackers were scanning for vulnerable devices and exploiting them en masse, which is exactly what happens when vendors ship questionable firmware and customers treat updates like they’re optional fucking side quests. Internet-exposed cameras are already a terrible idea; internet-exposed cameras with known vulnerabilities are practically a written invitation saying, “Come in, steal the furniture, and kick the dog on your way out.”

The likely goal here was botnet expansion, because hijacked cameras are cheap, plentiful, always on, and usually administered with the sort of care normally reserved for an office plant someone forgot existed. Once compromised, these devices can be used for further malicious activity, including DDoS attacks and other delightful bullshit that spills over onto the rest of the internet. So your bargain-bin camera doesn’t just watch your driveway — it can also moonlight as a tiny black-box soldier in someone else’s criminal clusterfuck.

The fix, unsurprisingly, is the same boring advice everyone ignores until their network starts coughing smoke: patch the damned firmware, stop exposing devices directly to the internet, restrict access, and generally behave like you’ve heard of basic security hygiene. If your security posture consists of plugging in IoT tat and hoping for the best, then congratulations, you’re basically running a charity for botnet operators.

Dahua apparently released updates for affected devices, which is lovely, but that only helps if somebody actually installs the bloody things. A patch sitting unread in a support portal is about as useful as a fire extinguisher still locked in the fucking cupboard while the server room burns down.

So the takeaway is simple: thousands of cameras got wrecked at speed because vulnerable devices were exposed online and left unpatched, and attackers did what attackers always do — they automated the hell out of it and cleaned up. Same story, different week, same avoidable mess caused by the unholy alliance of crap device security and human laziness.

Anecdote time: years ago, I watched a smug manager insist that patching embedded devices was “too disruptive,” right up until his precious networked kit joined a botnet and started flinging traffic around like a chimp with a bucket of shit. Suddenly downtime was acceptable after all. Funny how that works.
