Threat Roundup for April 30 to May 7


Today, Talos is publishing a glimpse into the most prevalent threats we've observed between April 30 and May 7. 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.Zusy-9857540-0 Trojan 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.Packed.Xcnfe-9856622-0 Packed Xcnfe is a generic name for the Dridex banking trojan that's downloaded onto a target's machine.
Win.Downloader.Upatre-9856675-0 Downloader Upatre is a malicious downloader often used by exploit kits and phishing campaigns. Upatre downloads and executes malicious executables such as banking malware.
Win.Packed.Tofsee-9856852-1 Packed Tofsee is multi-purpose malware that features several modules to carry out various activities such as sending spam messages, conducting click fraud, mining cryptocurrency and more. Infected systems become part of the Tofsee spam botnet and are used to send large volumes of spam messages to infect additional systems and increase the overall size of the botnet under the operator's control.
Win.Packed.Razy-9857213-0 Packed Razy is oftentimes a generic detection name for a Windows trojan. The malware collects sensitive information from the infected host and encrypts the data before sending it to a command and control (C2) server. Information collected might include screenshots. The samples modify auto-execute functionality by setting and creating a value in the registry for persistence.
Win.Dropper.DarkComet-9856982-1 Dropper DarkComet and related variants are a family of remote access trojans designed to provide an attacker with control over an infected system. Capabilities of this malware include the ability to download files from a user's machine, mechanisms for persistence and hiding, and the ability to send back usernames and passwords from the infected system.
Win.Packed.Phorpiex-9857011-1 Packed Phorpiex is a trojan and worm that infects machines to deliver follow-on malware. Phorpiex has been known to drop a wide range of payloads — from malware to send spam emails, to ransomware and cryptocurrency miners.
Win.Dropper.Bifrost-9857090-1 Dropper Bifrost is a backdoor with more than 10 variants. Bifrost uses the typical server, server builder and client backdoor program configuration to allow a remote attacker, who uses the client to execute arbitrary code on the compromised machine. Bifrost contains standard RAT features including a file manager, screen capture utility, keylogging, video recording, microphone and camera monitoring, and a process manager. Bifrost uses a mutex that may be named "Bif1234," or "Tr0gBot" to mark its presence on the system.
Win.Trojan.Zegost-9857108-0 Trojan Zegost is a remote access trojan 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. Zegost appears to be derived from Gh0stRAT, which is a well-known remote access trojan that had its source code leaked, thus significantly lowering the barrier to entry for actors looking to modify and reuse the code in new attacks.

Exploit Prevention

Cisco AMP for Endpoints protects users from a variety of malware functions with exploit prevention. Exploit prevention helps users defend endpoints from memory attacks commonly used by obfuscated malware and exploits. These exploits use certain features to bypass typical anti-virus software, but were blocked by AMP thanks to its advanced scanning capabilities, even protecting against zero-day vulnerabilities.

Process hollowing is a technique used by some programs to avoid static analysis. In typical usage, a process is started and its obfuscated or encrypted contents are unpacked into memory. The parent then manually sets up the first stages of launching a child process, but before launching it, the memory is cleared and filled in with the memory from the parent instead.
Excessively long PowerShell command detected - (4198)
A PowerShell command with a very long command line argument that may indicate an obfuscated script has been detected.

Kovter injection detected - (438)
A process was injected into, most likely by an existing Kovter infection. Kovter is a click fraud Trojan that can also act as an information stealer. Kovter is also file-less malware meaning the malicious DLL is stored inside Windows registry and injected directly into memory using PowerShell. It can detect and report the usage of monitoring software such as wireshark and sandboxes to its C2. It spreads through malicious advertising and spam campaigns.
