6M Sky Routers Vulnerable to Cyberattacks for Near 18 Months

6M Sky routers have been left exposed to cyberattacks for almost 18 months, that meaning a year and a half while the company was trying to remediate a DNS rebinding flaw in the routers of the customers. Sky is a UK-based provider of broadband, Sky Broadband being a service employed by Sky UK.

Pen Test Partners, a pen testing company offering cybersecurity solutions, announced to Sky Broadband about this issue, as they also stated in the post they wrote about this topic. On the 11th of May 2020, they reported the found issue to Sky and then continuously reached to the company for updates which apparently were constantly postponed.
