UNC1069 Targets Cryptocurrency Sector with New Tooling and AI-Enabled Social Engineering
North Korean threat actors continue to evolve their tradecraft to target the cryptocurrency and decentralized finance (DeFi) verticals. Mandiant recently investigated an intrusion targeting a FinTech entity within this sector, attributed to UNC1069, a financially motivated threat actor active since at least 2019. This investigation revealed a tailored intrusion resulting in the deployment of seven unique malware families, including a new set of tooling designed to capture host and victim data: SILENCELIFT, DEEPBREATH and CHROMEPUSH. The intrusion relied on a social engineering scheme involving a compromised Telegram account, a fake Zoom meeting, a ClickFix infection vector, and reported usage of AI-generated video to deceive the victim.

TeamPCP Worm Exploits Cloud Infrastructure to Build Criminal Infrastructure
Cybersecurity researchers have called attention to a massive campaign that has systematically targeted cloud native environments to set up malicious infrastructure for follow-on exploitation. The activity, observed around December 25, 2025, and described as worm-driven, leveraged exposed Docker APIs, Kubernetes clusters, Ray dashboards, and Redis servers, along with the recently disclosed React2Shell (CVE-2025-55182, CVSS score: 10.0) vulnerability. The campaign has been attributed to a threat cluster known as TeamPCP (aka DeadCatx3, PCPcat, PersyPCP, and ShellForce). TeamPCP is known to be active since at least November 2025, with the first instance of Telegram activity dating back to July 30, 2025. The TeamPCP Telegram channel currently has over 700 members, where the group publishes stolen data from diverse victims across Canada, Serbia, South Korea, the U.A.E., and the U.S. Details of the threat actor were first documented by Beelzebub in December 2025 under the name Operation PCPcat.

New Clickfix Variant ‘CrashFix’ Deploying Python Remote Access Trojan
In January 2026, Microsoft Defender Experts identified a new evolution in the ongoing ClickFix campaign. This updated tactic deliberately crashes victims’ browsers and then attempts to lure users into executing malicious commands under the pretext of restoring normal functionality. This variant represents a notable escalation in ClickFix tradecraft, combining user disruption with social engineering to increase execution success while reducing reliance on traditional exploit techniques. The newly observed behavior has been designated CrashFix, reflecting a broader rise in browser-based social engineering combined with living-off-the-land binaries and Python-based payload delivery. Threat actors are increasingly abusing trusted user actions and native OS utilities to bypass traditional defences, making behaviour-based detection and user awareness critical.

VoidLink: Evidence That the Era of Advanced AI-Generated Malware Has Begun
Check Point Research (CPR) believes a new era of AI-generated malware has begun. VoidLink stands as the first evidently documented case of this era, as a truly advanced malware framework authored almost entirely by artificial intelligence, likely under the direction of a single individual. Until now, solid evidence of AI-generated malware has primarily been linked to inexperienced threat actors, as in the case of FunkSec, or to malware that largely mirrored the functionality of existing open-source malware tools. VoidLink is the first evidence based case that shows how dangerous AI can become in the hands of more capable malware developers. Operational security (OPSEC) failures by the VoidLink developer exposed development artifacts. These materials provide clear evidence that the malware was produced predominantly through AI-driven development, reaching a first functional implant in under a week.

Dissecting and Exploiting CVE-2025-62507: Remote Code Execution in Redis
A recent stack buffer overflow vulnerability in Redis, assigned CVE-2025-62507, was fixed in version 8.3.2. The issue was published with a high severity rating and assigned a CVSS v3 score of 8.8. According to the official advisory, “a user can run the XACKDEL command with multiple IDs and trigger a stack buffer overflow, which may potentially lead to remote code execution”. Memory corruption vulnerabilities have become significantly harder to exploit due to the many security mitigations introduced over the years, but historically they easily led directly to remote code execution. Given that the vulnerability was rated as high severity but not classified as critical, the JFrog Security Research team decided to investigate the issue further and evaluate whether remote code execution is still easily achievable in 2026.

DNS OverDoS: Are Private Endpoints Too Private?
We discovered an aspect of Azure’s Private Endpoint architecture that could expose Azure resources to denial of service (DoS) attacks. In this article, we explore how both intentional and inadvertent acts could result in limited access to Azure resources through the Azure Private Link mechanism. We uncovered this issue while investigating irregular behavior in Azure test environments. Our research indicates that over 5% of Azure storage accounts currently operate with configurations that are subject to this DoS issue. This issue has the potential to affect organizations in multiple ways. For example, denying service to storage accounts could cause Azure Functions within FunctionApps and subsequent updates to these apps to fail. In another scenario, the risk could lead to DoS to Key Vaults, resulting in a ripple effect on processes that depend on secrets within the vault.
