A September 2014 article by Susan Bradley shows that Comcast does too (she also did not look into the state of the firewall and remote administration). Interestingly, none of the ISPs were named in the report.Ī recent experience with an Arris gateway (combination modem/router) tells me that Time Warner distributes devices configured with default passwords (I did not test if the box was also accessible from the Internet). These numbers can only suggest an issue with a default settings, as it is very unlikely that thousands of users who know to change their remote admin configurations would not bother to change their default passwords. Igal Zeifman, the head researcher behind the report said by email: In one case we saw an ISP with over 15,000 compromised routers and in another one with over 2,500 similarly vulnerable devices. The worst botnet they ran across consisted 'of a large number of SOHO routers, predominantly ARM-based Ubiquiti devices.' It is thought that the security mis-configuration was due to the ISP rather than Ubiquiti. More than 85 percent of the hacked routers are in Thailand and Brazil. Why so much malware? The report says that 'based on the profile of targets and the attack patterns, we know these compromised routers are being exploited by several groups or individuals.' One of those groups was Anonymous. on average, each compromised router held four variants of Mr.Black malware, as well as additional malware files, including Dofloo and Mayday, which are also used for DDoS attacks.' It's malware Fight Club on those poor routers. But not just one copy of the malware, no, '. Incapsula found malware called Mr.Black on most of the routers. The vulnerable routers were brutally attacked.
