Both ends of the remote-support cable went bad on the same day
ConnectWise disabled five ScreenConnect extensions after rogue clients reached 288 endpoints at 48 organisations, and inside about a day N-able pulled hosted N-central offline over more than 30 publicly dropped zero-days.
Here is the shape of it. ConnectWise is investigating an active campaign in which compromised ScreenConnect environments were used to push rogue remote-access clients down to customer devices, delivering something Huntress is calling SCKit; the count so far is at least 288 endpoints across 48 organisations, and ConnectWise has disabled five third-party extensions in partner environments while saying there is no evidence its own infrastructure was compromised. Separately, and roughly a day either side of it, N-able took hosted N-central environments offline and shipped hotfixes after a researcher published zero-days over the weekend — more than thirty of them, thirty-three by Dark Reading's count, good for remote code execution, credential theft and the creation of administrator accounts.
The mechanisms are not the same. One is abuse of an extension model that was working exactly as designed; the other is a pile of vulnerabilities that were not. So I am not going to tell you it is one coordinated wave, because I cannot see that from here. What I will tell you is that both products exist for the same reason, which is that somebody somewhere needs to reach into a thousand machines they have never physically touched, and that is a capability, not a product category. The capability is the target. It always was.
There is a version of this incident in which it is nobody's fault: supported software, legitimate tooling, a supplier relationship that is contractual and insured and has a logo on the website. That version is the ontologically inconvenient one, because it means there was no moment of negligence to point at in the timeline. You bought the ability to run commands on everything. Someone else is now exercising it.
Why it mattersIf you have an MSP, your blast radius today is their session history: hunt for unexpected ScreenConnect clients and extensions, and treat any N-central box that was internet-facing over the weekend as owned until proven otherwise.
