Read MoreIntroduction This year we are releasing our 2019 Application Protection Report as a series of short, tightly focused episodes. This helps ensure we provide timely threat intelligence that our readers can add to their own threat models and use to prepare appropriate defenses and responses. Last episode, we focused on PHP’s continuing run as one…
Read MoreAs we can see in Figure 8, the developers for SG Optimizer added a permission_callback command to the newly registered REST API routes. This indicates that prior to version 5.0.13, the SG Optimizer plugin had various privilege escalation vulnerabilities. Those vulnerabilities allowed any threat actor to send a malicious request to these registered REST API…
Read MoreThe table in Figure 4 shows the top 50 ASNs attacking Australia from Dec 1, 2018 to March 1, 2019 in order of highest to lowest number of attacks. Interestingly, these top 50 networks were split fifty-fifty between ISPs and hosting companies whereas the company types attacking other regions lean heavier towards ISPs. For comparison,…

However, advanced actors have more time and resources on their hands, and can fashion something of value even from apparently useless data. Large caches of innocuous information, such as email addresses, can be used to look for…
Read MoreSecurity researchers at F5 Networks constantly monitor web traffic at various locations throughout the world. This allows us to detect “in the wild” malware, and to get an insight into the current threat landscape. Here’s an overview of what we saw in May 2019. Throughout the month of May, the team detected 10 new attack…
Read MoreF5 researchers uncovered a cryptominer campaign delivering new Golang malware that targets Linux-based servers. Golang malware is not often seen in the threat landscape; it was first seen to mid-2018 and has continued throughout 2019. The malware campaign propagates using 7 different methods: 4 web application exploits (2 targeting ThinkPHP, 1 targeting Drupal, and 1…
