Kaspersky Warns Of Crypto-Stealing Malware In SourceForge Microsoft Package—Here's How to Stay Protected

In This Article:

  • Kaspersky has recently found crypto-stealing malware disguised as a Microsoft Office package on SourceForge.

  • While the malware primarily tricks users into sending crypto to bad actors, Kaspersky warns that the threat extends far beyond that.

  • Thousands of users have encountered this scheme in the past three months.

As crypto adoption grows, so too does interest from bad actors.

In likely evidence of this trend, warnings of security threats have ramped up in recent weeks, from Threat Fabric’s Crocodilus malware warning to Kaspersky‘s recent Triada Trojan warning. In the latest instance, Kaspersky is back with a warning of yet another security risk facing crypto users.

A Malicious “Officepackage”

Kaspersky has recently found crypto-stealing malware disguised as a Microsoft (NASDAQ:MSFT) Office package on SourceForge, a popular software hosting and distribution platform.

Don't Miss:

In a Tuesday blog post, the cybersecurity outfit warned of a project it found on SourceForge called “officepackage,” which posed as a legitimate Microsoft Office add-in project but redirected users to another website to download malware disguised as pirated Microsoft Office applications.

Once downloaded, Kaspersky explains that the malware scans the system for previous infections and antivirus software, deleting itself if it finds either. But if the system passes both checks, the malware quickly sends out a message of key system data through a Telegram API, sets up several re-entry measures and delivers its payload, the so-called ClipBanker.

ClipBanker is a malicious code that replaces cryptocurrency addresses in a system’s clipboard with the attacker’s own. This exploit is particularly potent as crypto users typically copy wallet addresses instead of typing them out to avoid errors. As such, ClipBanker turns what is usually a safety precaution into the user’s undoing.

Still, the threat of the officepackage scheme may extend beyond stealing cryptocurrencies.
