A new malware-as-a-service (MaaS) called TrustConnect has been discovered masquerading as a legitimate remote monitoring and management (RMM) tool. The malware, classified as a remote access trojan (RAT), uses a fake business website as its command and control center and MaaS portal. Priced at $300 per month, it offers features like a web-based C2 dashboard, automated payload generation with digital signatures, and remote desktop capabilities. The malware has been distributed through various email campaigns, often alongside legitimate RMM tools. Proofpoint researchers identified links between TrustConnect's creator and previous users of Redline stealer. The emergence of this new MaaS demonstrates the ongoing evolution of the cybercrime market and the thriving ecosystem of RMM abuse.

TA584, a prominent initial access broker targeting organizations globally, demonstrated significant changes in attack strategies throughout 2025. The actor expanded its global targeting, adopted ClickFix social engineering techniques, and began delivering new malware called Tsundere Bot. TA584's operational tempo increased, with monthly campaigns tripling from March to December. The actor uses various delivery methods via email, often sending from compromised individual accounts. TA584's campaigns now feature rapid succession and overlapping, with distinct lure themes and short operational lifespans. The actor has shown adaptability in social engineering, brand impersonation, and payload delivery, making static detection less effective. Recent payloads include XWorm with the 'P0WER' configuration and the newly observed Tsundere Bot, both likely part of Malware-as-a-Service offerings.
