550,000-strong army of Mac zombies spreads across world

Infected machines, not blank-eyed shuffling fanbois

The Mac-specific Flashback Trojan created a zombie army of 550,000 Mac machines by exploiting a Java hole that Apple only patched on Tuesday, six weeks after Microsoft plugged it up on Windows machines.

This is according to Russian anti-virus firm Dr Web, which arrived at the figure after it successfully managed to sinkhole one of the command-and-control servers used to control Mac machines hit by the latest attack. The legions of compromised zombies were mostly located in the US (56.6 per cent, or 303,449 infected hosts), Canada (19.8 per cent, or 106,379 infected computers) and the UK (12.8 per cent or 68,577 cases of infection).

Kaspersky claims ‘smoking code’ linking Stuxnet and Duqu

Warns of three other unknown variants

Researchers at Kaspersky Lab are claiming to have found proof that the writers of the Stuxnet and Duqu malware are one and the same, and are warning of at least three new families of advanced malware potentially in circulation.

Security experts have been debating if the two code groups are by the same authors, but the evidence has been inconclusive. An analysis by NSS last month suggested that the two were linked, but this might be down to reverse engineering, rather than the original coding.

Alexander Gostev, chief security expert at Kaspersky Lab, said that researchers had examined drivers used in both Stuxnet and Duqu and concluded that a single team was most likely behind them both, based on the timing of their creation and their methods of interacting with the rest of the malware code.
