- There is a new Microsoft malware document masking itself as one made with Windows 11 Alpha.
- The malicious documents exploit VBA macros to successfully infiltrate the system.
- The FIN7 group is suspected to be behind this attack, given their previous history in similar cases.
Microsoft users have one more thing to worry about. A security research firm has discovered a new Microsoft Word document malware. The maldoc masks itself as a document made on Windows 11 Alpha. Anomali Threat Research has discovered six similar malicious malware and warns users to be vigilant as Microsoft tries to stay on top of the situation.
Microsoft has been facing malware attacks in the recent past where attackers have been impersonating familiar and commonly used productivity tools to launch an attack. The malware document discovered is named “Users-Progress-072021-1.doc”.
Attack took place in late June
The chain of infection first started with an image that masqueraded to have been made with Windows 11 Alpha. The image tasked users to ‘Enable content’ or ‘Enable editing’ for the next step.
A Twitter user named NinjaOperator took to Twitter to question whether FIN7 was behind the attack when the news broke out.
Users are lured using instructions on document’s cover
Users familiar with Windows 11 builds and variations are less likely to suffer from the attack, but others may fall for this trick and run the file.
The malware document can perform several checks such as:
- Memory capacity
- VM check
- CLEARMIND check
CLEARMIND is a domain for a POS service provider. FIN7 is known for targeting such domains to gain access to large-scale data.
The group continues to be active despite measures taken to bring the attacks to an end. Users are warned to remain extra vigilant on all files.
