An active campaign has been observed targeting internet-exposed instances running ComfyUI, a popular stable diffusion platform, to enlist them into a cryptocurrency mining and proxy botnet. "A purpose-built Python scanner continuously sweeps major cloud IP ranges for vulnerable targets, automatically installing malicious nodes via ComfyUI-Manager if no exploitable node is already present," Censys security researcher Mark Ellzey said in a report published Monday. The attack activity, at its core, systemically scans for exposed ComfyUI instances and exploits a misconfiguration that allows remote code execution on unauthenticated deployments through custom nodes . Upon successful exploitation, the compromised hosts are added to a cryptomining operation that mines Monero via XMRig and Conflux via lolMiner, as well as to a Hysteria V2 botnet. Both of them are centrally managed through a Flask-based command-and-control (C2) dashboard. Data from the at...

An Iran-nexus threat actor is suspected to be behind a password-spraying campaign targeting Microsoft 365 environments in Israel and the U.A.E. amid ongoing conflict in the Middle East. The activity, assessed to be ongoing, was carried out in three distinct attack waves that took place on March 3, March 13, and March 23, 2026, per Check Point. "The campaign is primarily focused on Israel and the U.A.E., impacting more than 300 organizations in Israel and over 25 in the U.A.E.," the Israeli cybersecurity company said . "Activity associated with the same actor was also observed against a limited number of targets in Europe, the United States, the United Kingdom, and Saudi Arabia." The campaign is assessed to have targeted the cloud environments of government entities, municipalities, technology, transportation, energy sector organizations, and private-sector companies in the region. Password spraying is a form of brute-force attack where a...

Threat actors likely associated with the Democratic People's Republic of Korea (DPRK) have been observed using GitHub as command-and-control (C2) infrastructure in multi-stage attacks targeting organizations in South Korea. The attack chain, per Fortinet FortiGuard Labs , involves obfuscated Windows shortcut (LNK) files acting as the starting point to drop a decoy PDF document and a PowerShell script that sets the stage for the next phase of the attack. It's assessed that these LNK files are distributed via phishing emails. As soon as the payloads are downloaded, the victim is displayed the PDF document, while the malicious PowerShell script runs silently in the background. The PowerShell script performs checks to resist analysis by scanning for running processes related to virtual machines, debuggers, and forensic tools. If any of those processes are detected, the script immediately terminates. Otherwise, it extracts a Visual Basic Scri...

Your attack surface no longer lives on one operating system, and neither do the campaigns targeting it. In enterprise environments, attackers move across Windows endpoints, executive MacBooks, Linux infrastructure, and mobile devices, taking advantage of the fact that many SOC workflows are still fragmented by platform.  For security leaders, this creates a costly operational gap : slower validation, limited early-stage visibility, more escalations, and more time for attackers to steal credentials, establish persistence, or move deeper before the response fully begins. The Multi-OS Attack Problem SOCs Aren’t Ready For A multi-OS attack can turn one threat into several different investigations at once. The campaign may follow a different path depending on the system it reaches, which breaks the speed and consistency SOC teams rely on during early triage. Instead of moving through one clear validation pro...

This week had real hits. The key software got tampered with. Active bugs showed up in the tools people use every day. Some attacks didn’t even need much effort because the path was already there. One weak spot now spreads wider than before. What starts small can reach a lot of systems fast. New bugs, faster use, less time to react. That’s this week. Read through it. ⚡ Threat of the Week Axios npm Package Compromised by N. Korean Hackers —Threat actors with ties to North Korea seized control of the npm account belonging to the lead maintainer of Axios, a popular npm package with nearly 100 million weekly downloads, to push malicious versions containing a cross-platform malware dubbed WAVESHAPER.V2. The activity has been attributed to a financially motivated threat actor known as UNC1069. The incident demonstrates how quickly the compromise of a popular npm package can have ripple effects through the ecosystem. T...
