Spam from the Government Secure Internet

gov.uk

Well that’s what it looks like. Criminals apparently from Bangalore have been distributing loads of malware spams from addresses like Nich***.Davi**.5208@vosa.gsi.gov.uk, and they’re getting through spam filters.

This all looks pretty genuine – they probably copied it verbatim with the exception of the “good afternoon”.

The payload is a Microsoft Word document with macros, but I’ve yet to figure out exactly what it’s doing. In the parlance of the security “industry” it’d be a zero-day exploit, but that’s not interesting. What did come as a bit of a surprise to me is that GSI doesn’t seem to bother with SPF records, which would have helped detect the fake. Bayesian analysis throws up nothing, and it’s coming from a clean IP address that has yet to be listed. The only things wrong with it are that there’s no reverse lookup, and no SPF on vosa.gsi.gov.uk to flag it as dodgy.

The civil service clearly hasn’t got this security business clear yet.
