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.

You can find an additional JSON file here that includes the IOCs in this post, as well as all hashes associated with the cluster. That list is limited to 25 hashes in this blog post. As always, please remember that all IOCs contained in this document are indicators, and one single IOC does not indicated maliciousness.

The most prevalent threats highlighted in this roundup are:

• Xls.Downloader.Sload-6774021-0
  Downloader
  The Sload downloader launches PowerShell and gathers information about the infected system. The PowerShell may download the final payload or another downloader.
  
• Doc.Downloader.Emotet-6765662-0
  Downloader
  Emotet is a banking trojan that has remained relevant due to its continual evolution to better avoid detection. It is commonly spread via malicious emails and saw a resurgence recently during Black Friday.
  
• Win.Ransomware.Imps-6765847-0
  Ransomware
  This is a trojan horse virus that may steal information from the affected machine and download potentially malicious files that spread via removable drives.
  
• Win.Virus.Sality-6765491-0
  Virus
  Sality is a file infector that establishes a peer-to-peer botnet. Although it's been prevalent for more than a decade, we continue to see new samples that require marginal attention in order to remain consistent with detection. Once a Sality client bypasses perimeter security, its goal is to execute a downloader component capable of executing additional malware.
  
• Win.Packed.Passwordstealera-6765350-0
  Packed
  This malware has the ability to harvest stored credentials, keystrokes, screenshots, network activity, and more from computers where the software is installed.
  
• Doc.Downloader.Sagent-6766662-0
  Downloader
  Sagent launches PowerShell through macros in Microsoft Office documents. The PowerShell then downloads unwanted software from remote websites.
