Worms are a malware tactic from back in the day - but they still remain tricky to mitigate against...
“It’s pretty aggressive, and it’s replicating very quickly.” That reads like the words of stressed system administrator affected by last week’s WannaCry (Wanna Decryptor) ransomware – but actually, that’s the reaction of a security expert from 13 years ago to a new variant of the Sasser worm.
WannaCry’s ransomware high jinks apart, the echoes with last Friday’s events are intriguing.
Just as WannaCry targets an oft-unpatched Windows SMB flaw, so in 2004 Sasser picked on the scab of unpatched Windows exploit in Local Security Authority Subsystem Service (LSASS – hence “Sasser”), which is – ironically – a bit of the OS used to manage security settings.
If you think WannaCry’s victim count is impressive, Sasser’s included not-to-be-sniffed-at names such as Deutsche Post, the European Commission and Delta Airlines, to name only a selection.
