The ZeroAccess botnet is one of the largest known botnets in existence today with a population upwards of 1.9 million computers, on any given day, as observed by Symantec in August 2013. A key feature of the ZeroAccess botnet is its use of a peer-to-peer (P2P) command-and-control (C&C) communications architecture, which gives the botnet a high degree of availability and redundancy. Since no central C&C server exists, you cannot simply disable a set of attacker servers to neuter the botnet. Whenever a computer becomes infected with ZeroAccess, it first reaches out to a number of its peers to exchange details about other peers in its known P2P network. This way, bots become aware of other peers and can propagate instructions and files throughout...

Attacks by viruses, trojans and other malware have often been considered as a Microsoft problem. Whilst Microsoft may have initially been slow to realise the significance and impact of malware, with  Windows XP Service Pack 2 and Microsoft’s Trustworthy Computing initiative, led by a former FBI agent, that the company started to get on top of the challenge.

Despite what the anti-Redmond crowd have blogged over the years, however, hackers didn’t target Microsoft products exclusively because they were insecure, or because the people involved had some ideological death-wish on the company. No – they did it because Microsoft was the most used end-point device environment in the world. Bill Gates’ “Windows Everywhere” ambition, once realised, made it the most obvious of all targets.

When times change, however, they don’t necessarily follow the script. In the personal computer era, the debate was about whether Linux (and more...
