Members of the public often get involved in security issues alongside professional researchers and organisations. What do you do in this situation? We’ll get to that but before we do, let’s talk about the perils of getting involved in situations. This means lots of compromised exchange servers all over the place, just waiting for illicit access to begin all over again. It’s likely that some also patched the vulnerability without also finding and removing the web shells. Or perhaps they just didn’t know what to do to fix the problem. Some organisations missed or ignored the mass-massaging about the threat. When calls to fix systems go unheededĭespite repeated warnings, and even one-click tools from Microsoft aiming to mitigate the issue, and no small amount of patching, some vulnerable servers remained. Having those shells lying around on systems for such a long time isn’t a great thing to happen. This means criminals figuring out the passwords to other criminals’ web shells could also potentially access the compromised servers. Additionally, it seems that not all shells were properly locked down. They allow attackers to access and creep around inside the compromised networks. Bizarrely, they did this without letting the admins know beforehand.Ī campaign targeting vulnerable Exchange servers has left web shells scattered everywhere. A press release from the US Department of Justice Judge has revealed that the FBI were granted permission to perform some tech support backdoor removal. A rather remarkable story has emerged, setting the scene for lively debates about permissible system access.
