Proofpoint threat researchers identified a new malware-as-a-service named #TrustConnect. Notably, it masquerades as a legitimate remote monitoring and management tool, marking an evolution in how attackers weaponize trust around enterprise tooling. See our blog for details: brnw.ch/21x05Vh.

Since 14 October, we’ve tracked a high volume XWorm campaign targeting Germany. The activity is attributed to TA584, a sophisticated #cybercrime group tracked since 2020. Messages are sent from hundreds of compromised sender accounts impersonating ELSTER and contain malicious URLs.

New ecrime insights: TA4557, known for distributing More_eggs malware, notably expanded to an international audience in recent campaigns. Per our data, the recruiter-focused TA was seen targeting orgs in France, England & Ireland, in addition to typical North America-targeted threats.

This article that starts getting traction claims that the official RVTools website was distributing a malicious installer leading to Bumblebee. I see zero evidence of this actually being the case. 1/2

There is however at least two separate current malvertising/SEO campaigns, one leading to Bumblebee and one leading to SMOKEDHAM/Thundershell, but it's not from the official website. 2/2

Proofpoint also recently observed this activity delivering GootLoader. Google Ads for a fake document creation app (lawliner[.]com) led to a malicious document creation website, on which users are directed to enter their email address.

Great research on that #GootLoader is now including email in their delivery chain. Please don't download NDAs and other contract templates from free sites without any history.
