Today, Talos is publishing a glimpse into the most prevalent threats we've observed between Aug. 12 and Aug. 19. 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.Ramnit-9964110-0
Dropper
Ramnit is a banking trojan that monitors web browser activity on an infected machine and collects login information from financial websites. It could also steal browser cookies and hide from popular antivirus software.
Win.Ransomware.Locky-9963624-0
Ransomware
Locky is ransomware typically distributed via spam emails containing a maliciously crafted Microsoft Word document crafted to trick targets into enabling malicious macros. This family was originally released in 2016 and updated over the years with additional functionality.
Win.Dropper.Shiz-9963681-0
Dropper
Shiz is a remote access trojan that allows an attacker to access an infected machine to harvest sensitive information. It is commonly spread via droppers or by victims visiting a malicious site.
Win.Dropper.XtremeRAT-9963701-0
Dropper
XtremeRAT is a remote access trojan active since 2010 that allows the attacker eavesdrop on users and modify the running system. The source code for XtremeRAT, written in Delphi, was leaked online and has since been used by similar RATs.
Win.Dropper.Nanocore-9963905-0
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.Ransomware.Cerber-9964084-0
Ransomware
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.Dropper.Dorkbot-9964085-0
Dropper
Dorkbot is a worm that spreads itself through social networking sites and messaging apps. Once installed, the infected computer becomes part of a botnet, allowing the controller to control the machine remotely.
Win.Worm.Kuluoz-9964104-0
Worm
Kuluoz, sometimes known as "Asprox," is a modular remote access trojan that is also known to download and execute follow-on malware, such as fake antivirus software. It often is delivered via spam emails pretending to be shipment delivery notifications or flight booking confirmations.
