Further 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 MoreIntroduction Welcome to F5 Labs’ third annual report on phishing and fraud. Once again, we’re bringing you data from our partner Webroot® as well as the F5 Security Operations Center. Phishing continues to be a major source of profit for cyber-criminals, and a big hassle for cyber-defenders. In the F5 Labs 2019 Application Protection Report,…
Read MoreViewed in this way, our research illuminates some interesting aspects of the current state of security. In 2018, to the extent that new attack techniques and approaches emerged, it was largely in response to changes in how organizations design, create, and manage applications. The context that makes old attack techniques like injection and phishing newly…
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 MoreCompletely investigating the underlying server architecture and CNC structure of banking trojans such as DanaBot is an area of continuing research for the F5 malware team. Conclusion As with all banking trojans, DanaBot actively updates its tactics, techniques, and target list to both avoid detection and maintain continual operations to optimize the attacker’s financial reward.…
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 Networks researchers have detected a new variant of the “Echobot” malware, now consisting of 71 exploits. The authors continue to follow the trend of arming the malware and for the threat group to expand its operation. These newly added exploits target both old and new vulnerabilities, adding as new ones target industrial control system…
Read MoreSecurity researchers at F5 Networks constantly monitor web traffic at various locations all over the world. This allows us to detect “in the wild” malware and get insights into the current threat landscape. In November 2019, new malicious campaign activity was down 40 percent compared to October 2019. While this seems like a large decline,…
Read MoreIn part 1, we discussed the various definitions of cloud and looked at cloud incidents related to data breaches, such as outages. In this part, we’re taking a close look at major cloud data breach incidents over the past few years. Are the majority of these breaches associated with sophisticated advanced attackers or malicious insiders?…
