Infostealers remain among the most pervasive cybercrime threats, silently harvesting passwords, cookies, and session tokens that enable enterprise breaches. StealC is a malware-as-a-service infostealer written in C++ that collects credentials from browsers, cryptocurrency wallets, messaging applications, email clients, and gaming platforms while functioning as a secondary loader. Amadey operates as a modular backdoor loader active since 2018, delivering downstream payloads including StealC, Lumma Stealer, and ransomware through various backdoor commands. Both operate on commodity rental models where stolen credentials flow through underground markets to access brokers who resell enterprise access. On June 24, 2026, Microsoft's Digital Crimes Unit coordinated with Europol to disrupt over 200 malicious command-and-control domains supporting these operations, using AI-assisted analysis tools including Microsoft Copilot for binary analysis and configuration extraction.

A massive network of over 20,000 fraudulent e-commerce domains has been uncovered, all sharing common infrastructure and design patterns. These fake shops, primarily using the .shop domain, are designed to steal payment details and personal data from unsuspecting consumers. The operation is highly industrialized, with domains resolving to just 36 IP addresses, indicating a franchise-style model where a core team manages servers and templates while individual operators launch storefronts. The shops use familiar e-commerce tactics and psychological pressure to lure victims. To protect yourself, use browser protection tools, scrutinize unfamiliar domains, be wary of deep discounts, and look for independent reviews before making purchases.

IBM X-Force discovered a likely AI-generated malware named 'Slopoly' used in a ransomware attack by the Hive0163 group. This marks the beginning of AI adoption among cybercrime groups, potentially transforming the threat landscape. Slopoly, while relatively unsophisticated, demonstrates how easily threat actors can use AI to develop new malware quickly. The attack involved ClickFix social engineering, NodeSnake malware, and InterlockRAT, culminating in the deployment of Interlock ransomware. This incident highlights the growing trend of AI-generated and AI-integrated malware, which could lead to more ephemeral and difficult-to-attribute attacks, challenging traditional threat intelligence methods.

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.

DragonForce, a ransomware group that emerged in late 2023, has become a significant cyber threat. They employ a dual-extortion strategy, encrypting and exfiltrating data, and have targeted various sectors, particularly manufacturing and construction. The group offers a flexible ransomware-as-a-service platform with advanced features, supporting multiple platforms and encryption modes. DragonForce has announced a shift to a cartel model, allowing affiliates to create their own brands. They've also introduced automated registration for new affiliates and a 'Company Data Audit' service to enhance extortion campaigns. The group has engaged in conflicts with rival ransomware operations and claims to have formed a coalition with other major groups. While their connection to DragonForce Malaysia remains unsubstantiated, technical analysis reveals similarities with other ransomware families and sophisticated attack techniques.

A Microsoft Teams voice-phishing campaign leveraging Quick Assist, a remote administration tool, was tracked in September 2025. The campaign uses help desk scams to gain initial access, followed by user group enumeration and the execution of a PowerShell script to download a command and control payload. The attack employs AMSI bypass, encrypted communications, and a web-socket remote access trojan. Multiple Microsoft 365 tenants with IT-related subdomains were used, along with various IPs and domains for C2 infrastructure. The campaign shows similarities to Storm-1811 and PhantomCaptcha activities, suggesting a complex cybercrime ecosystem. The attackers' ultimate goal may be ransomware deployment, although observed attempts were successfully blocked.

A multi-domain traffic distribution system (TDS) operation was discovered, centered around the domain toxicsnake-wifes.com. The infrastructure serves as a commodity cybercrime TDS farm, routing victims to phishing, scams, or malware payloads. The operation uses a first-stage JavaScript loader, followed by a second-stage that attempts to fetch upstream payloads. The cluster shares common WHOIS, DNS, and hosting patterns, indicative of bulletproof VPS usage. Multiple burner domains with similar tradecraft were identified, suggesting an organized operator cluster. The infrastructure employs obfuscation, dynamic remote injection, and disposable registration techniques. While the main payload was unreachable during analysis, historical evidence suggests the delivery of malicious content.

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.

A Vietnamese threat actor is employing AI to develop code for an ongoing phishing campaign delivering PureRAT malware and other payloads. The attacks begin with phishing emails disguised as job opportunities, potentially targeting work computers. The attacker's use of AI is evidenced by detailed comments and numbered steps in scripts, as well as instructions in debug messages. The attack chain involves malicious archives, sideloaded DLLs, and batch scripts likely authored using AI. The attacker appears to be continually refining their methods and may be selling access to compromised organizations. This case demonstrates how AI can lower the barrier to entry for less skilled attackers, helping them write code and build attack toolkits.

An analysis of Chinese hosting environments reveals over 18,000 active command-and-control (C2) servers distributed across 48 infrastructure providers. C2 infrastructure dominates malicious activity at 84%, followed by phishing at 13%. China Unicom hosts nearly half of all observed C2 servers, with Alibaba Cloud and Tencent following. A small set of malware families, including Mozi, ARL, and Cobalt Strike, accounts for most C2 activity. The infrastructure supports both cybercrime and state-linked operations, with RATs, cryptominers, and APT tooling coexisting. High-trust networks like China169 Backbone and CERNET are actively exploited. This host-centric approach exposes long-running abuse patterns and infrastructure reuse across campaigns, enabling more resilient threat detection and mitigation strategies.
