Spying on Tibetan sympathisers and activists: Double Dockster*

Does the expression 'In the Wild' still mean anything today? Well yes, in the sense of something that is 'out there' threatening real-world systems. But things move a lot faster these days than they did in the 90s and later, fastburning mass-mailers notwithstanding. Just a few days ago (on the 30th of November, to be

Flashback Wrap Up

Six months ago, Flashback was attracting a lot of attention from researchers and media due to its wide spread and interesting features.

Fighting the OSX/Flashback Hydra

The biggest Mac botnet ever encountered, the OSX/Flashback botnet, is being hit hard. On April 12th, Apple released a third Java update since the Flashback malicious code outbreak.

MacDefender undergoes a name change, MacShield

The MacDefender malware has morphed again, now taking the guise of "MacShield."   As in the case of its oldest sibling MacDefender, the MacShield variant has taken the name of a legitimate Mac OSX software product with small distribution, doubtless causing the real developer significant heartache. The UI is essentially unchanged, but as usual all

MacDefender: The sky is not falling…

In the last few days, I have been asked by a journalist (or four) what MacDefender means for the future of Apple security, and if I thought there was excess hype around it.   I'll address the second question first.   I think its safe to say the current malware would not be newsworthy if
