FireEye confirms another attack on critical infrastructure

Vadim Ghirda / AP

Security firm FireEye disclosed some details Thursday of a recent attack on a critical infrastructure provider by what appears to be either a state actor or state-sponsored actors.

While it isn't sharing most of the details, FireEye is drawing attention to one key element unique to this attack. In this case, the malware in question was successful at defeating two systems, but in doing so appeared to inadvertently trip up another system, causing at least some interruption of service.

Why it matters: In many cases, nations may be trying to infiltrate key infrastructure to have a way in should they wish to attack, but aren't necessarily looking to do damage now. This incident shows in some cases they may be doing damage nonetheless.
