From IcedID to Dagon Locker Ransomware in 29 Days
From IcedID to Dagon Locker Ransomware in 29 Days
  • In late August 2023, we observed an intrusion that started with a phishing campaign using PrometheusTDS to distribute IcedID. IcedID dropped and executed a Cobalt Strike beacon, which was then used through-out the intrusion. The threat actor leveraged a bespoke PowerShell tool known as AWScollector to facilitate a range of malicious activities including discovery, lateral movement, data exfiltration, and ransomware deployment. Group Policy was used to distribute Cobalt Strike beacons at login to a specific privileged user group. The threat actor utilized a suite of tools to support their activities, deploying Rclone, Netscan, Nbtscan, AnyDesk, Seatbelt, Sharefinder, and AdFind. * This case had a TTR (time to ransomware) of 29 days.

From OneNote to RansomNote: An Ice Cold Intrusion - The DFIR Report
From OneNote to RansomNote: An Ice Cold Intrusion - The DFIR Report
  • In late February 2023, threat actors rode a wave of initial access using Microsoft OneNote files. In this case, we observed a threat actor deliver IcedID using this method. After loading IcedID and establishing persistence, there was no further actions, other than beaconing for over 30 days. The threat actor used Cobalt Strike and AnyDesk to target a file server and a backup server. * The threat actor used FileZilla to exfiltrate data from the network before deploying Nokoyawa ransomware.

In this intrusion from May 2022, the threat actors used BumbleBee as the initial access vector from a Contact Forms campaign. We have previously reported on two BumbleBee intrusions (1, 2), and this report is a continuation of a series of reports uncovering multiple TTPs seen by BumbleBee post exploitation operators. The intrusion began with the delivery of an ISO file that contained an LNK and a DLL. The threat actors leveraged BumbleBee to load a Meterpreter agent and Cobalt Strike Beacons. They then performed reconnaissance, used two different UAC bypass techniques, dumped credentials, escalated privileges using a ZeroLogon exploit, and moved laterally through the environment.
