The majority of the scanning activity is coming from IP addresses assigned to just a handful of ASNs, mostly AS49870 (Alsycon, a hosting provider out of the Netherlands) and AS47890 (Unmanaged Ltd, what looks to be an IT consulting firm based out of the UK). The scanners appear to be using VPS or other resources…
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 MoreShellshock can take advantage of HTTP headers as well as other mechanisms to enable unauthorized access to the underlying system shell, Bash. The Shellshock attack takes advantage of a flaw in Bash that enables attackers to execute remote commands that would ordinarily be blocked. It’s been rated the highest risk possible because remote command execution…
Read MoreTinba, also known as “Tinybanker”, “Zusy” and “HµNT€R$”, is a banking Trojan that was first seen in the wild around May 2012. Its source code was leaked in July 2014. Cybercriminals customized the leaked code and created an even more sophisticated piece of malware that is being used to attack a large number of popular…
Read MoreWebinject attacks modify webpages to allow fraudsters to collect credentials, or act more directly against user accounts. The newsidron.com script injection serves as a good example of how these attacks are conducted, detected, and ultimately stopped. A Trojan is a piece of malware that appears to the user to perform a desirable function, but…
Read MoreStandard mobile banking trojans post their own fraudulent content over banking applications. The Yasuo-Bot malware takes it a step further by dynamically pulling fraudulent content from the C&C server. Since 2010, mobile malware is on the rise. The first mobile Trojan launched was Zitmo (Zeus in the mobile), a mobile version of the most…
Read MoreMore Complexity to Come The profession of webinject crafting is being reflected in Trojan campaigns against banks. We can only guess whether the resemblance between the webinjects is a result of a cooperation or of both fraudsters buying webinjects from the same third party. Either way, a great deal of fraud business logic is now…
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 MoreIn the event that you have a WAF in place and are hacked (likely, in the scenario where you have implemented the solution in monitoring/listen-only mode), the collection of the post data will be your primary evidence source that indicates how your application was exploited. This information is critical in your investigation and remediation…
Read MoreThe encapsulated IP packet header uses the same parameters as the encapsulating IP header. The Transport Layer protocol for the encapsulated IP packet is UDP. Most public routers will pass along the GRE packet because it’s a widely used protocol for generating VPN connections. We speculate that GRE might be the protocol of choice due to…
