During 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…

While analyzing this script which downloads and executes the cryptominer, F5 researchers found that the code is sophisticated, well obfuscated, and long—about 200 lines versus the typical 20 or so lines. The authors clearly put a lot of time and attention into every step, from developing the malware dropper to creating the executable JAR file…

Use 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.”…

Viewed 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…

Completely 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.…

  Web Application Security Our biggest research story of the year was our 2019 Application Protection Series, which focused on looking at an entire year of application-related breaches as well as a year of global web attack traffic. In that story, we noted how PHP vulnerabilities comprise 81% of the attack traffic, much of it…

Welcome to the Summary of the 2019 F5 Labs TLS Telemetry Report. This year, we expanded the scope of our research to bring you deeper insights into how encryption on the web is constantly evolving. We look into which ciphers and SSL/TLS versions are being used to secure the Internet’s top websites and, for the…

Authentication Attacks: Growing Every Year Credential stuffing and brute force attacks have been the biggest threats for financial services recently, and the trend shows no sign of slowing. This is unsurprising, given the capability that legitimate credentials represent for attackers. If attackers are able to guess or simply re-use already compromised credentials and gain access…

This is the full-spectrum, director’s cut version of the Application Protection Report, untrammeled by petty concerns like brevity or toner prices (for the shorter version, please see our Summary). This report pulls together the various threats, data sources, and patterns in the episodes into a unified line of inquiry that began in early 2019, picking…
