The Russian threat actor known as APT28 (aka Forest Blizzard and Pawn Storm) has been linked to a fresh spear-phishing campaign targeting Ukraine and its allies to deploy a previously undocumented malware suite codenamed PRISMEX . "PRISMEX combines advanced steganography, component object model (COM) hijacking, and legitimate cloud service abuse for command-and-control," Trend Micro researchers Feike Hacquebord and Hiroyuki Kakara said in a technical report. The campaign is believed to be active since at least  September 2025. The activity has targeted various sectors in Ukraine, including central executive bodies, hydrometeorology, defense, and emergency services, as well as rail logistics (Poland), maritime and transportation (Romania, Slovenia, Turkey), and logistical support partners involved in ammunition initiatives (Slovakia, Czech Republic), and military and NATO partners. The campaign is notable for the rapid weaponization of newly disclosed ...

The North Korea-linked persistent campaign known as Contagious Interview has spread its tentacles by publishing malicious packages targeting the Go, Rust, and PHP ecosystems. "The threat actor's packages were designed to impersonate legitimate developer tooling [...], while quietly functioning as malware loaders, extending Contagious Interview’s established playbook into a coordinated cross-ecosystem supply chain operation," Socket security researcher Kirill Boychenko said in a Tuesday report. The complete list of identified packages is as follows - npm: dev-log-core, logger-base, logkitx, pino-debugger, debug-fmt, debug-glitz PyPI: logutilkit, apachelicense, fluxhttp, license-utils-kit Go: github[.]com/golangorg/formstash, github[.]com/aokisasakidev/mit-license-pkg Rust: logtrace Packagist: golangorg/logkit These loaders are designed to fetch platform-specific second-stage payloads, which turn out to be a piece of malware with infostealer and remo...

Iran-affiliated cyber actors are targeting internet-facing operational technology (OT) devices across critical infrastructures in the U.S., including programmable logic controllers (PLCs), cybersecurity and intelligence agencies warned  Tuesday. "These attacks have led to diminished PLC functionality, manipulation of display data and, in some cases, operational disruption and financial loss," the U.S. Federal Bureau of Investigation (FBI) said in a post on X. The agencies said the campaign is part of a recent escalation in cyber attacks orchestrated by Iranian hacking groups against U.S. organizations in response to the ongoing conflict between Iran, and the U.S. and Israel. Specifically, the activity has led to PLC disruptions across several U.S. critical infrastructure sectors via what the authoring agencies described as malicious interactions with the project file and manipulation of data on human-machine interface (HMI) and supervisory control an...

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...
