Malware hits London hospitals

It’s interesting to speculate how three seperate hospital computer systems have managed to simultaneously fall victim to malware. See Given that the rest of us have not today fallen victim to anything new, and that other hospitals appear to still be functioning, it looks like a highly targeted attack. The Register reports that it might be a case of the Mytob worm however, I’m dubious: Mytob is more nuisance malware rather than disruptive, it’s signature is well known, and I doubt it would result in the networks of three hospitals being so thoroughly disrupted. If it were a new variant evading the anti-malware protection, then we’d all be seeing it.
