The US Department of Homeland Security Cybersecurity and Infrastructure Security Agency (DHS CISA) has cited ransomware as “the most visible cybersecurity risk” attacking American IT systems. I think that’s a valid statement, since “most visible” doesn’t necessarily mean largest or most devastating, but it does still qualify ransomware as a significant threat. Indeed, it seems…
Read MoreDuring June and July, F5 researchers first noticed Trickbot campaigns aimed at a smaller set of geographically oriented targets and did not use redirection attacks—a divergence from previous Trickbot characteristics. In this research, we compared two different target configurations, one older, more “traditional” configuration that uses redirection, and a new Trickbot configuration that does not…
Read MoreFurther analysis on this sample was not conducted. F5 Labs has reported extensively on the Mirai botnet, IoT landscape, and some of its variants. For a detailed breakdown on current Mirai botnets seen in the threat landscape, the Hunt for IoT Research Series publishes current threat data. Conclusion All of the vulnerabilities targeted this month…
Read MoreUse of Cyber Deception to Influence Voters Rather than directly manipulate votes, cyber attackers are now finding success in misleading the voters themselves. Once again, social engineering triumphs over technology. The key to this tactic is simple, and cyberwarfare researcher The Grugq said it best, “People will believe what their computers tell them is reality.”…
Read MoreA vulnerable FortiGate SSL VPN server responds to this request with contents of the sslpvpn_websession file, which contains the username and password of a user. This information can be used or sold to threat actors in order to compile brute force and credential stuffing lists. While reconnaissance campaigns do not actively exploit systems, they enable…
Read MoreIP Addresses Attacking the Middle East Compared to Other Regions We looked at the volume of attack traffic Middle Eastern systems received per IP address and compared that to other regions of the world. Attack traffic destined for Middle Eastern systems had little overlap with the rest of the world except for a handful of…
Read MoreThe script uses random function and variable names to avoid detection by antivirus engines. It also contains another Base64-encoded payload. The threat actor uses .Net APIs to call the Windows API. For example, the script uses the .NET API to find address of VirtualAlloc function exported by kernel32.dll. It then marshals the shellcode by using…
Read MoreLatin American systems received more attacks from IP addresses within the region that coincidentally did not attack anywhere else in the world. Source link lol
Read MoreThe cloud, like every other technology, was developed to help us do more things faster and more efficiently. It’s a business tool that provides the self-service flexibility of on-demand technological services decoupled from the need to physically deliver hardware and software. Organizations are flocking to leverage this power, but there are nagging questions: Is cloud…
Read MoreF5 Labs, in conjunction with our partner Baffin Bay Networks, researches global attack traffic region to region to gain a deeper understanding of the cyber threat landscape. Aside from attack campaigns targeting the entire Internet (IPv4 address space), the attack landscape varies regionally in terms of sources, targets, and attack types. In addition, targeted ports…
