Threat Roundup for April 9 to April 16


Today, Talos is publishing a glimpse into the most prevalent threats we've observed between April 9 and April 16. 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.Packed.Dridex-9850858-1 Packed Dridex is a well-known banking trojan that aims to steal credentials and other sensitive information from an infected machine.
Win.Dropper.Emotet-9850949-0 Dropper Emotet is one of the most widely distributed and active malware families today. It is a highly modular threat that can deliver a wide variety of payloads. Emotet is commonly delivered via Microsoft Office documents with macros, sent as attachments on malicious emails.
Win.Virus.Xpiro-9851061-1 Virus Expiro is a known file infector and information-stealer that hinders analysis with anti-debugging and anti-analysis tricks.
Win.Malware.Zegost-9851864-0 Malware Zegost, also known as Zusy, 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.TinyBanker-9852021-1 Dropper TinyBanker, also known as Zusy 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.TrickBot-9851512-0 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.Packed.Kovter-9851593-0 Packed Kovter is known for its fileless persistence mechanism. This family of malware creates several malicious registry entries which store its malicious code. Kovter is capable of reinfecting a system, even if the file system has been cleaned of the infection. Kovter has been used in the past to spread ransomware and click-fraud malware.
Win.Packed.ZeroAccess-9851602-1 Packed ZeroAccess is a trojan that infects Windows systems, installing a rootkit to hide its presence on the affected machine and serves as a platform for conducting click fraud campaigns.
Win.Malware.Ursu-9851621-0 Malware Ursu is a generic malware that has numerous functions. It contacts a C2 server and performs code injection in the address space of legitimate processes. It achieves persistence and collects confidential data and is spread via email.

MITRE ATT&CK





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 detected - (14099)
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 - (2793)
A PowerShell command with a very long command line argument that may indicate an obfuscated script has been detected. PowerShell is an extensible Windows scripting language present on all versions of Windows. Malware authors use PowerShell in an attempt to evade security software or other monitoring that is not tuned to detect PowerShell based threats.
Reverse tcp payload detected - (1793)
An exploit payload intended to connect back to an attacker controlled host using tcp has been detected.
A Microsoft Office process has started a windows utility. - (1524)
A process associated with Microsoft Office, such as EXCEL.exe or WINWORD.exe, has started a Windows utility such as powershell.exe or cmd.exe. This is typical behavior of malicious documents executing additional scripts. This behavior is extremely suspicious and is associated with many malware different malware campaigns and families.
Crystalbit-Apple DLL double hijack detected - (1133)
Crystalbit-Apple DLL double hijack was detected. During this attack, the adversary abuses two legitimate vendor applications, such as CrystalBit and Apple, as part of a dll double hijack attack chain that starts with a fraudulent software bundle and eventually leads to a persistent miner and in some cases spyware deployment.
Squiblydoo application whitelist bypass attempt detected. - (678)
An attempt to bypass application whitelisting via the "Squiblydoo" technique has been detected. This typically involves using regsvr32.exe to execute script content hosted on an attacker controlled server.
Kovter injection detected - (579)
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.
Dealply adware detected - (468)
DealPly is adware, which claims to improve your online shopping experience. It is often bundled into other legitimate installers and is difficult to uninstall. It creates pop-up advertisements and injects advertisements on webpages. Adware has also been known to download and install malware.
Cobalt Strike activity detected - (157)
Cobalt Strike is a tool used by both penetration testers and malicious actors. It has been observed being used to deliver Ryuk ransomware and other payloads.
Gamarue malware detected - (94)
Gamarue is a family of malware that can download files and steal information from an infected system. Worm variants of the Gamarue family may spread by infecting USB drives or portable hard disks that have been plugged into a compromised system.
