In-brief: three quarters of embedded systems that sport web interfaces tested by researchers at universities in Germany and France contained serious security vulnerabilities, according to a new study. The results raise more questions about the security of embedded devices including home routers and home surveillance cameras.
A mysterious piece of software, dubbed Wifatch, has been infecting tens of thousands of Linux-based home routers and, according to experts at Symantec, attempts to secure them from attack. But Wifatch’s benevolent intentions shouldn’t obscure its malicious actions, or the security problems that it takes advantage of. The malicious software runs on vulnerable, Linux-based home routers. There, it removes other malware infections, disables vulnerable services like Telnet and even prompts users to update their administrator user name and password to prevent compromise, according to a post on Symantec’s blog. But the malware is still spreading between vulnerable systems without the owners consent and could easily be pressed into service distributing spam or malicious software, experts note. According to Symantec, Wifatch is likely spreading between infected devices by targeting exposed Telnet interfaces and using brute force password attacks to gain access to the devices. Tens of thousands of devices may have been infected […]
In-brief: A hard coded firmware password could provide remote hackers with access to a wide range of home broadband routers, underscoring the risk posed by shared hardware and software, according to an alert from Carnegie Mellon University’s CERT this week.
In-brief: Jackson Shaw of Dell warns that home networks are like the Wild West frontier when it comes to threats to the Internet of Things. Your broadband router is the covered wagon.
If you want an object lesson in the dangers that await us on the Internet of Things, check out SEC Consult’s write up on NetUSB, a widely used technology developed by an obscure Taiwanese company that just happens to contain a nasty, remotely exploitable vulnerability. According to this alert, published on Tuesday, NetUSB “suffers from a remotely exploitable kernel stack buffer overflow” that could be used to run malicious code on affected devices. Even worse: the NetUSB component is ubiquitous – found in a long list of devices, from low-end wireless access points and broadband routers for small office and home office deployments to what SEC Consult called “high end devices…released very recently.” Networking devices from 26 vendors, including TP-Link, NetGear and others were found to use the NetUSB technology in their products. The vulnerability discovered by SEC Consult is straight-forward enough. According to their advisory, the NetUSB code does an inadequate […]
