PHANTOMPULSE is a sophisticated RAT attributed to DPRK-aligned actors that utilizes hardware breakpoints to bypass AMSI, WLDP, and ETW. It establishes a resilient, sinkhole-able command and control channel by resolving C2 URLs from blockchain transaction inputs and employs multiple process injection and UAC bypass techniques.
Session Hijacking and Developer Tool Poisoning Collapse Authentication Trust This week, attackers proved that multi-factor authentication is no longer a reliable gatekeeper. Campaigns like Tycoon 2FA and Chinese-language PhaaS platforms intercept one-time passwords in real time and steal session tokens to maintain persistent access, while infostealers like EKZ Infostealer harvest browser cookies to bypass authentication entirely. Even when victims reset passwords and revoke sessions, attackers retain access through hidden device registrations — meaning standard incident response playbooks are now incomplete. Developers remain the preferred entry point for supply chain compromise. The Glassworm botnet was disrupted after hiding malware in VSCode extensions and npm packages, while the Megalodon campaign poisoned GitHub Actions workflows across 5,500 repositories. A malicious Sicoob.Sdk NuGet package stole banking certificates from Brazilian developers, and North Korea's Lazarus group compromised the widely used axios npm library — a single attack touching millions of downstream applications. Organizations must move beyond password-and-MFA reliance: adopt hardware security keys, shorten session lifetimes, delete attacker-registered devices before resetting credentials, and audit developer toolchains and CI/CD pipelines for tampering.
ESET's Q4 2025–Q1 2026 APT Activity Report highlights global espionage and destructive campaigns by state-aligned actors. Notable incidents include a major supply chain compromise of the 'axios' npm library by Lazarus, destructive wiper attacks on Polish critical infrastructure by Sandworm, and the deployment of new edge-device implants like PhiliKit against Ivanti VPNs by China-aligned groups.
North Korean state-sponsored actors, including Lazarus and TraderTraitor, are highly motivated to access advanced AI models to accelerate their labor-intensive cryptocurrency heists. The primary attack vectors are not direct breaches of AI cryptographic perimeters, but rather supply chain compromises, fraudulent hiring of DPRK IT workers, and third-party contractor misuse.
Arctic Wolf Labs identified a highly targeted campaign by the DPRK-nexus threat actor BlueNoroff against the Web3 sector. The attackers utilize sophisticated social engineering, including AI-generated deepfakes and stolen webcam footage, to lure victims into fake Zoom or Teams meetings. Once engaged, a ClickFix clipboard injection attack deploys a fileless PowerShell C2 implant, leading to the theft of cryptocurrency wallets, browser credentials, and Telegram sessions.
Lazarus Group is conducting a new ClickFix campaign targeting macOS users in high-value sectors via Telegram. The attackers trick victims into executing a terminal command that deploys 'Mach-O Man,' a multi-stage Go-based malware kit designed to steal credentials, browser data, and macOS Keychain secrets, exfiltrating the data via Telegram.
AI Weaponization Collapses Trust as Identity Becomes the Perimeter Attackers are using artificial intelligence to make phishing and social engineering dramatically cheaper and more convincing, as seen in BlueNoroff's AI-generated deepfake meetings targeting Web3 executives and the Bluekit phishing platform's built-in AI assistant that crafts lures on demand. Because these AI tools can generate convincing scams and steal session cookies to bypass multi-factor authentication, traditional email filters and basic MFA are no longer sufficient barriers. In parallel, attackers are shifting from hacking infrastructure to hijacking identity and trust systems—installing legitimate remote-access tools via phishing, exploiting API authentication flaws like BOLA, and harvesting credentials through malicious AI browser extensions that spy on users in real time. This identity-focused shift compounds with the persistent exploitation of older vulnerabilities; groups like SHADOW-EARTH-053 still use years-old ProxyLogon flaws on unpatched Exchange servers, while CISA confirms CVE-2026-32202 (Microsoft Windows) and CVE-2026-41940 (cPanel) are already being exploited in the wild. Because AI models like Claude Mythos can now autonomously chain these vulnerabilities into working exploits at machine speed, defenders cannot rely on manual patching cadences to stay safe. These trends together suggest that the real perimeter is no longer the firewall but the identity layer, and defending it requires phishing-resistant authentication, automated response, and rigorous vetting of developer pipelines and third-party trust. Watch for AI-accelerated exploitation of unpatched systems and invest in identity-centric, machine-speed defenses before the next wave of automated attacks outpaces your team's response.
