If open ports are found, Internet of Things Scanner will advise on corrective action, which can include modifying the router’s configuration. Open ports that might be indicative of a vulnerability are supposed to show up in the scans. That refreshed page, called the Internet of Things Scanner, powered by BullGuard, allows users to check if devices on a network are publicly accessible from the internet. “Scan your IoT devices to see if they may have participated in yesterday’s DDoS,” Fistagon7 writes, linking to a new version of Shodan. Interestingly, Reddit-user Fistagon7 points out that Shodan services can be used to see if Reddit members participated in the aforementioned, and now-famous, IoT-originating DDoS attack last week. Mapped, visual representations of connected IoT devices, such as open cameras around the world, are depicted. Shodan, still active, is a search engine that trawls the internet looking for port-connected devices. With the partial collapse of the internet last week, reportedly caused by home network Internet of Things (IoT) security cameras creating holes for DDoS attacks, I’m reminded of the Shodan IoT open port searching website that I wrote about in 2014. “The results clearly show that routers can be attacked fairly easily,” the article says.ĮSET also says port scanning during its testing showed that in numerous cases, network services were accessible from internal networks, as well as from external networks. Cross-site scripting (XSS) vulnerabilities, which allow hackers to change router setups and run bogus scripts, made up 8 percent. The command injection vulnerabilities made up 39 percent of the failings. What ESET researchers call “the Sednit group” is merely a set of software and the related network infrastructure, without any correlation with any specific organization.Of that 7 percent of the now-common household devices with software vulnerabilities, about half (53 percent) had “bad access rights vulnerabilities,” or permissions problems, in other words. Performing attribution in a serious, scientific manner is a delicate task that is beyond the scope of our security researchers. The discovery of the LoJax UEFI rootkit shows that the Sednit APT group is even more advanced and dangerous than was previously thought, according to Jean-Ian Boutin, the ESET senior malware researcher who led the research into the recent Sednit campaign.Īs for attribution, ESET does not perform any geopolitical attribution. This group has a diversified set of malware tools in its arsenal, several examples of which ESET researchers have documented in their previous white paper as well as in numerous blog posts on WeLiveSecurity. The Democratic National Committee hack that affected the US 2016 elections, the hacking of global television network TV5Monde, the World Anti-Doping Agency email leak, and many others are believed to be the work of Sednit. Such groups are known to conduct cyber espionage and other cyberattacks on high profile targets. ![]() Sednit, operating since at least 2004 and also known as APT28, STRONTIUM, Sofacy and Fancy Bear, is one of the most active APT (Advanced Persistent Threat) groups. The recent discovery of LoJax, the first-ever UEFI rootkit detected in a real computer attack, shows that UEFI rootkits may become a regular part of advanced computer attacks.įortunately, thanks to the ESET UEFI Scanner, our customers are in an excellent position to spot such attacks. So ESET decided to invest in the ability to protect its customers from UEFI firmware-facilitated attacks. ![]() Any data (files, videos, microphones, etc.) on the computer or network it's connected to can be stolen or hijacked for the attacker's own use. However, such attacks have the potential to take over complete control of computers and networks. UEFI firmware-facilitated attacks are sporadic, and up to now, they were mostly limited to physical tampering with the target computer. ![]() While some other vendors may have technologies with “UEFI” in their names, their purpose is different than what a true firmware scanner should do.īeing the only vendor offering UEFI scanning illustrates ESET’s approach to protection. ESET is the only vendor among the Top 20 endpoint security solutions vendors (by revenue) that provides users with UEFI scanning technology implemented in its endpoint protection solutions.
