An extremely specific attack targeting certain types of router appears to have broken the internets of more than 100,000 customers that use the Post Office's branded ISP service, with the malware worming its way into the Zyxel AMG1302 as issued by the Post Office and the DSL-3780 router used by some TalkTalk subscribers.
The attack is powered by a bespoke version of the the Mirai worm, one spread by breached computers and designed to infect hardware based on some splinters of the Linux OS. The Post Office says it's already rolling out a fix, saying: "We would like to reassure customers that no personal data or devices have been compromised. We have identified the source of the problem and implemented a resolution which is currently being rolled out to all customers. For those customers who are still having problems, we are advising them to reboot their router."
Some users of Hull's niche Kcom ISP have also been hit, while TalkTalk says it has added "additional network-level controls" to hopefully fend off any further attempts to cripple the fun boxes of subscribers. [BBC]
