Threat Roundup for May 20 to May 27


Today, Talos is publishing a glimpse into the most prevalent threats we've observed between May 20 and May 27. As with previous roundups, this post isn't meant to be an in-depth analysis. Instead, this post will summarize the threats we've observed by highlighting key behavioral characteristics, indicators of compromise, and discussing how our customers are automatically protected from these threats.

As a reminder, the information provided for the following threats in this post is non-exhaustive and current as of the date of publication. Additionally, please keep in mind that IOC searching is only one part of threat hunting. Spotting a single IOC does not necessarily indicate maliciousness. Detection and coverage for the following threats is subject to updates, pending additional threat or vulnerability analysis. For the most current information, please refer to your Firepower Management Center, Snort.org, or ClamAV.net.

For each threat described below, this blog post only lists 25 of the associated file hashes and up to 25 IOCs for each category. An accompanying JSON file can be found here that includes the complete list of file hashes, as well as all other IOCs from this post. A visual depiction of the MITRE ATT&CK techniques associated with each threat is also shown. In these images, the brightness of the technique indicates how prevalent it is across all threat files where dynamic analysis was conducted. There are five distinct shades that are used, with the darkest indicating that no files exhibited technique behavior and the brightest indicating that technique behavior was observed from 75 percent or more of the files.

The most prevalent threats highlighted in this roundup are:

Threat Name Type Description
Win.Dropper.Chthonic-9950427-1 Dropper Chthonic is a banking trojan derived from the Zeus family of banking malware. It is typically spread via phishing emails and attempts to steal sensitive information from an infected machine. Chthonic has also been observed downloading follow-on malware such as Azorult, another information stealer.
Win.Dropper.Emotet-9950400-0 Dropper Emotet is one of the most widely distributed and active malware families today. It is a modular threat that can deliver a variety of payloads. Emotet is commonly delivered via Microsoft Office documents with macros, sent as attachments on malicious emails.
Win.Dropper.Gh0stRAT-9950358-1 Dropper Gh0stRAT is a well-known family of remote access trojans designed to provide an attacker with complete control over an infected system. Capabilities include monitoring keystrokes, collecting video footage from the webcam, and uploading/executing follow-on malware. The source code for Gh0stRAT has been publicly available on the internet for years, significantly lowering the barrier for actors to modify and reuse the code in new attacks.
Win.Dropper.Trickbot-9950352-0 Dropper Trickbot is a banking trojan targeting sensitive information for certain financial institutions. This malware is frequently distributed through malicious spam campaigns. Many of these campaigns rely on downloaders for distribution, such as VB scripts.
Win.Dropper.Zusy-9950333-0 Dropper Zusy, also known as TinyBanker or Tinba, is a trojan that uses man-in-the-middle attacks to steal banking information. When executed, it injects itself into legitimate Windows processes such as "explorer.exe" and "winver.exe". When the user accesses a banking website, it displays a form to trick the user into submitting personal information.
Win.Dropper.Ursnif-9950326-0 Dropper Ursnif is used to steal sensitive information from an infected host and can also act as a malware downloader. It is commonly spread through malicious emails or exploit kits.
