Sure, the C&C list is a small sample size, and C&C hosts come and go quickly. This list is in no way exhaustive—it’s just a snapshot in time from last quarter. But for a breakdown of the domain hosting services, see the end of this article. “Yes, I really am a C&C server.” A…
Read MoreF5 security researchers analyzed the Ramnit banking trojan campaign that was active over the holiday season and discovered it’s not much of a banking trojan anymore. 64% of its targets were retail eCommerce sites, including Amazon.com, Best Buy, Forever 21, Gap, Zara, Carter’s, OshKosh B’gosh, Macy’s, Victoria’s Secret, H&M, Overstock.com, Toys“R”Us, Zappos, and many others.…
Read MoreEvery day, your web servers are increasingly being scanned—and likely attacked—by adversaries attempting to gain access to your infrastructure. Between 2015 and 2017, our data partner, Loryka, observed these types of scans grow from 200 per minute to as much as 2,000 per minute. These kinds of attackers are professionals; they do this for a…
Read MoreLast week, a malware campaign targeting Jenkins automation servers was reported by CheckPoint researchers.1 The attackers exploited a deserialization vulnerability2 in Jenkin’s bidirectional channel (CVE-2017-1000353)3 to deploy Monero cryptomining malware that generated an estimated profit of $3 million. Following this disclosure, F5 researchers observed what appears to be the same threat actor group, as they…
Read MoreF5 threat researchers detected attackers actively exploiting the rTorrent client through a previously undisclosed misconfiguration vulnerability and deploying a Monero (XMR) crypto-miner operation. The rTorrent client misconfiguration vulnerabilities include: No authentication required for XML-RPC communication Sensitive XML-RPC method is allowed (direct OS command execution) Attackers are actively exploiting this vulnerability in the wild by scanning…
Read MoreAn advanced thingbot, nicknamed Reaper (or IoTroop), was recently discovered infecting hordes of IoT devices. Reaper ups the ante for IoT security. It has a sophisticated C2 channel system and a Lua code execution environment (to deliver much more complicated attacks), and it comes prepackaged with 100 DNS open resolvers. Researchers are tracking Reaper, even…
Read MoreFigure 2: Latest attack request targeting Windows servers As shown in Figure 2, the latest attack requests are targeting the same URL, keeping the same HTTP header values and the same exploit structure, however, they are now using Windows shell commands to download and execute a file.

Read MoreExecutive Summary Like coral reefs teeming with a variety of life, web applications are “colony creatures.” They consist of a multitude of independent components, running in separate environments with different operational requirements and supporting infrastructure (both in the cloud and on premises) glued together across networks. In this report, we examine that series of interacting…
Read MoreEver wonder what security professionals see as their main barrier to achieving a strong application security posture? We wondered that, too, so we asked them. As part of F5 Labs’ first annual Application Protection Report, F5, in conjunction with Ponemon Institute, surveyed security professionals on a slew of security-related topics. In answer to this particular…
