The Mozi botnet has been documented as able to conduct HTTP, TCP, UDP, and other attacks. More information can be found in the April 2024 Sensor Intel Series article. [back to top] And Another Step Back: Emerging DDoS Attack Vectors HTTP/2 Abuse The relatively new HTTP/2 protocol (new in internet terms, since the protocol is…
Read MoreBy looking at the table of supported IP protocols, we see that the bot creates raw packets of IGMP, ICMP and TCP protocols. Those packets are just being marked with those protocol numbers, however other fields and headers are not actually set. The packet is filled with “A” characters according to the size specified by…
Read MoreIf an attacker wants to launch a powerful Low and Slow DDoS attack, surprisingly, he or she will find only a single tool in this bundle. That is the well-known Slowloris.pl Perl tool, which is not authored by Anonymous at all. R.U.D.Y and other slow POST tools are noticeably missing from this bundle. Another group…
Read MoreThe latest evolution of cyber weaponry is brought to you by the default passwords in Internet of Things (IoT) devices. That includes just about every conceivable modern electronic device—from home thermostats, lighting systems, refrigerators, cars, and water meters, to personal fitness devices, toasters, bicycle helmets, toys, and even shoes and clothing. Today, the number…
Read MoreSo far, we’ve seen IoT Distributed Denial-of-Service (DDoS) attacks on a Death Star scale. Even if your organization wasn’t a direct target of these giant barrages, many others were caught up as collateral damage because they had services adjacent or dependent on the direct target. Because of this, many organizations are preparing or strengthening their…
Read MoreBut that’s not the worst news coming out of this survey. No, not by any stretch of the imagination is that the bad news. Sit down and strap in, because it gets much worse. In spite of pushing vulnerable applications into production (and into the hands of consumers), a staggering 44% admitted they aren’t doing anything to…
Read MoreAll businesses watch their bottom line. That’s unsurprising. Those that provide technology to consumers (whether IoT device manufacturers or your local ISP that provides your home router) are particularly careful about balancing product support with ease of use. That can lead to what the inventors no doubt believe is an ingenious method of determining passwords…
Read MoreOn the shoulders of manufacturers lies the responsibility to address vulnerabilities, because the next generation of thingbots is taking advantage of known vulnerabilities to gain control of devices. Persirai is an adaptation of Mirai that shares code as well as command and control servers, but targets all models of IP cameras from a single Chinese…
Read MoreFigure 5. 60 seconds C&C polling interval However, although the malware is still evolving, it has good market differentiation in its HTTP functionality. Being based on Android’s WebView class, the thingbot is better equipped with browser-like functionality, making it more resistant to various bot challenges, such as cookie support, redirects, and JavaScript, which are…
Read MoreI recently had the opportunity to sit down with two of F5’s top threat researchers, Sara Boddy and Justin Shattuck, to pick their brains about IoT, its current state of “security,” and what we can expect to see in terms of threats, attacks, and mitigations in the future. Justin and Sara are co-authors of three IoT threat research…
