In 2018 we published our first Application Protection Report, which summarized trends and attack patterns for 2017 across multiple disciplines of information security and offered a big picture strategy for controlling application risk. We created that report in order to provide three things that we felt the security industry needs: a specific focus on application…
Read MorePoor security is another clue that young novices are operating botnets. The Owari authors left their command and control (C&C) MySQL database wide open (port 3306), “protected” with both the username and password of “root.” Control of IoT devices is a highly competitive market, where rivals commonly DDoS each other. In one case, a competing…
Read MoreThen there are the technical questions that need to be answered. What data will be captured, shared, and processed? What mobile platforms will the app run on? What server-side platforms will it need to talk to? Internal platforms? Third-party services? You also need to dig into the questions of expectations and dependencies. How important will…
Read MoreThe next step in this process is to convert the decrypted and decompressed data file from binary into a human readable format. The following python snippet provides a regular expression that will roughly split the injects from one another: import re regex_res = re.split(‘[x00]{1}[x00-xff]{7}[x00]{2}[x01-xff]{1}’, data[7:]) The steps outlined here can be used on the different…
Read MoreIn part one, we laid out how we should react when our organization tells us they want to roll out a mobile app. Short answer: don’t say no, but instead ask lots of questions. After that, we built a threat model that includes the mobile-specific twists on traditional IT security problems. Using this model, we…
Read MoreThe 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 MoreIntroduction Ten months ago we asked a rhetorical question: will losses from cryptocurrency exchange hacks hit one billion dollars in 2018? Indeed, they did. Cryptocurrency theft is growing both in terms of frequency of attacks and breadth of targets. Attackers aren’t just cryptojacking and targeting exchanges. According to endpoint security provider Carbon Black, $1.1 billion…
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 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 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.…
