Threat Roundup for May 6 to May 13


Today, Talos is publishing a glimpse into the most prevalent threats we've observed between May 6 and May 13. 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.Trojan.Qakbot-9949393-1 Trojan Qakbot, aka Qbot, has been around since at least 2008. Qbot primarily targets sensitive information like banking credentials but can also steal FTP credentials and spread across a network using SMB.
Win.Packed.Upatre-9949356-0 Packed Upatre is a malicious downloader often used by exploit kits and phishing campaigns. Upatre downloads and executes malicious executables such as banking malware.
Win.Dropper.Cerber-9949361-0 Dropper Cerber is ransomware that encrypts documents, photos, databases and other important files. Historically, this malware would replace files with encrypted versions and add the file extension ".cerber," although in more recent campaigns, other file extensions are used.
Win.Trojan.Hupigon-9949365-0 Trojan Hupigon is a trojan that installs itself as a backdoor on a victim's machine.
Win.Dropper.LokiBot-9949439-0 Dropper Lokibot is an information-stealing malware designed to siphon off sensitive information stored on an infected device. It is modular in nature, supporting the ability to steal sensitive information from a number of popular applications. It is commonly pushed via malicious documents delivered via spam emails.
Win.Malware.Barys-9949519-0 Malware This is a trojan and downloader that allows malicious actors to upload files to a victim's computer.
Win.Trojan.Ursnif-9949968-0 Trojan Ursnif steals sensitive information from an infected host and can act as a malware downloader. It is commonly spread through malicious emails or exploit kits.
Win.Malware.Gh0stRAT-9949686-0 Malware 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.
