Today, Talos is publishing a glimpse into the most prevalent threats we've observed between Oct. 13 and Oct. 20. 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.Zeus-10011479-0 Dropper Zeus is a trojan that steals information such as banking credentials using methods such as key-logging and form-grabbing. Win.Downloader.Upatre-10011416-0 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.CoinMiner-10011305-1 Packed This malware installs and executes cryptocurrency-mining software. Win.Dropper.Remcos-10011195-0 Dropper Remcos is a remote access trojan (RAT) that allows attackers to execute commands on the infected host, log keystrokes, interact with a webcam, and capture screenshots. This malware is commonly delivered through Microsoft Office documents with macros, sent as attachments on malicious emails. Win.Malware.Zusy-10010855-0 Malware 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.AgentTesla-10010785-1 Packed AgentTesla is a remote access rojan that records keystrokes and attempts to steal sensitive information from web browsers and other installed applications. Win.Trojan.Tofsee-10010766-0 Trojan Tofsee is multi-purpose malware that features a number of modules used 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 in an effort to infect additional systems and increase the overall size of the botnet under the operator's control. Win.Dropper.Glupteba-10010808-0 Dropper Glupteba is a multi-purpose trojan that is known to use the infected machine to mine cryptocurrency and steals sensitive information like usernames and passwords, spreads over the network using exploits like EternalBlue, and leverages a rootkit component to remain hidden. Glupteba has also been observed using the Bitcoin blockchain to store configuration information. Win.Dropper.Nanocore-10011208-0 Dropper Nanocore is a .NET remote access trojan. Its source code has been leaked several times, making it widely available. Like other RATs, it allows full control of the system, including recording video and audio, stealing passwords, downloading files and recording keystrokes. Win.Dropper.DarkComet-10011490-1 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.
