Wacatac is a detection name used by Microsoft Defender to mark a range of threats that possess spyware-like capabilities conjoined with malware delivery functionality. Wacatac malware is exceptionally dangerous and should be treated with maximum caution.
What is Wacatac?
It’s a detection name of an entire selection of malware that operates as spyware. Another distinctive feature of this threat is the ability to deliver other malware, i.e. act as a dropper. A lot of modern malware contains both of these functions, that’s why seeing Wacatac detection became quite common.
There is a possibility that the threat detected is more of a dropper malware rather than a stealer or spyware. Since droppers collect certain info about the system as a fingerprint, Microsoft Defender may understand such behavior as data gathering. Even though this data amount is not nearly as all-encompassing and exposing, the reason for the detection is quite clear.
|Data stealing, Malware delivery
|Spyware, Infostealer, Banking Trojan, Dropper
|Malicious email attachments, cracked programs from third-party sites
|Trojan:Win32/Wacatac.B!ml (“B Ml” variant), Trojan:Win32/Wacatac.H!ml (“H ml” variant”), Trojan:Script/Wacatac.H!ml (“Script” variant)
How Dangerous is Trojan:Win32/Wacatac?
Eventually, two main vectors of danger come from Wacatac malware. Spyware functions make it worrying for user privacy – it extracts passwords, and cookie files, and even grabs session tokens. Dropper capabilities make things even worse: by bringing other malware, hackers who operate it increase their profits.
Some of the malware samples detected as Wacatac may be aimed at specific topics, like cryptocurrency wallets or online banking accounts. Such threats trade broad-range stealing for inflicting severe financial damage. With that being said, nothing stops cybercriminals from starting with a “regular” spyware, and bringing banking trojans, cryptostealers or ransomware as a second-stage payload.
Examples of Malware Detected as Trojan Wacatac
Wacatac is not a specific malware family but a group of malware that falls under the same category due to its functionality. There are a couple of families that Microsoft Defender detects with this name the most.
|An infamous malware, among the most active at the moment (late 2023). Is used to deliver Vidar, RedLine stealers and STOP/Djvu ransomware. May sporadically deliver cryptominers. Gathers basic data about the system.
|Originally a stealer, Gozi received malware delivery functionality as a plug-in. Though, it is mainly used as a spyware.
|Emotet (Epoch 4 variants)
|One of the most known malware samples over the last 6 years. Conjoins the functionality of dropper and stealer, being equally used for both purposes. Defender usually marks this malware family as Sabsik, though changes in Epoch 4 version probably altered its signature, making it more similar to Wacatac.
|Old-timer of malware scene, mostly used in targeted attacks as a tool for initial reconnaissance and lateral movement. Its network was recently shut down, so a new spreading wave may start quite soon.
|Also known as xLoader. Being active since 2016, it conjoins the functionality of a stealer and a dropper. Still, it is known far less than Emotet.
