Malicious Tool Versions Target IT Staff

By Netvora Tech News

A group of criminals has set its sights on IT personnel by distributing malicious versions of various tools. In some cases, Microsoft Bing has pointed users to these malicious versions. According to security experts, the attackers are using a technique called typosquatting, registering domain names that are identical to the original, but with a slight misspelling or different extension.

These fake domains appear in Microsoft Bing search results, offering users a compromised version of the software. The campaign, which has been discovered to involve WinMTR, Zenmap, and RVTools, is just the tip of the iceberg. Researchers have found many more malicious domains with names of well-known software.

RVTools Under Attack

Last week, a report emerged that a malicious version of RVTools had been used in attacks. Security firm ZeroDay Labs claimed that a Trojanized version of RVTools had been distributed via the official website. However, it appears this was another case of typosquatting. ZeroDay Labs has since removed the article without further comment.

About the Tools

RVTools is a tool for managing VMware environments. Similarly, fake websites have been discovered for WinMTR and Zenmap. WinMTR is an open-source project that provides a visual interface for Matt's / My Traceroute, used to troubleshoot network problems. Zenmap is a graphical user interface for the network scanner Nmap.

The Bumblebee Malware

The compromised versions offered through the typosquatting domains contain the Bumblebee malware. This malware acts as a "downloader" and can download additional malware, such as ransomware, onto the system. Several ransomware attacks have been linked to the Bumblebee malware.

Security researcher German Fernandes warns, "As we've said so many times, don't blindly trust advertisements/suggestions from any page, search engine, or AI. Be cautious of what you click, research, and verify."
