Last week tens of thousands of TalkTalk and Post Office broadband customers were cut off after a cyber attack left them with no internet connection. Since the incident last Sunday, up to 360,000 TalkTalk users and 100,000 Post Office customers across the country reported interruptions of service.
Here’s what we know about the attack so far. It is said to involve some variant of the Marai worm, with several types of routers being affected by the malware. This includes the Zyxel AMG302 distributed by the Post Office and the D-Link DSL-3780 used by a small percentage of TalkTalk customers. Hull’s internet provider Kcom and 900,000 of Germany’s Deutsche Telekom customers were also affected.
If you’ve been affected, the advice from the Post Office is to reboot your router and don’t worry because your data is safe.
A spokesman for the company said: “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.”
He continued: “For those customers who are still having problems, we are advising them to reboot their router.”
TalkTalk announced that they are “reviewing the potential impacts” of the malicious software, and that they have already added emergency security measures.
In a full statement, a spokesperson said: “Along with other internet service providers in the UK and abroad, we are taking steps to review the potential impacts of the Mirai worm. “
They continued: “A small number of customer routers have been affected, and we have deployed additional network-level controls to further protect our customers.”
Despite this, customers from TalkTalk and the Post Office complained both companies had done little to keep them in the loop about the problems. As of this week the broadband issues appear to have been fixed.
