CERT-In Recommends 12-Hour Patching for Internet-Facing Flaws Amid AI-Assisted Attacks

CERT-In Recommends 12-Hour Patching for Internet-Facing Flaws Amid AI-Assisted Attacks

May 26, 2026 Artificial Intelligence / Cloud Security,
The Indian Computer Emergency Response Team (CERT-In) has issued new guidelines requiring organizations to patch critical security vulnerabilities in internet-exposed systems within 12 hours of being flagged where "feasible" to safeguard against potential threats stemming from threat actors' abuse of artificial intelligence (AI) tools and large language models (LLMs) to automate vulnerability discovery and exploitation, and enhance the scale and velocity of cyber attacks. "AI-assisted cyber exploitation reduces the time required for adversaries to identify, weaponize, and exploit vulnerabilities, exposed services, weak identities, insecure APIs, and misconfigured systems," CERT-In said in a 38-page blueprint published Monday. "As organizations become increasingly dependent on interconnected digital infrastructure, cloud ecosystems, software supply chains, operational technologies, and AI-enabled platforms, the potential impact of AI-enabled cyber thr...

Iranian Hackers Deploy MiniFast and MiniJunk V2 via Phishing and SEO Poisoning

May 26, 2026 Cyber Espionage / Artificial Intelligence
The Iranian state-sponsored threat actor known as Nimbus Manticore (aka Screening Serpens and UNC1549 ) has been attributed to a fresh campaign using lures impersonating organizations in the aviation and software sectors across the U.S., Europe, and the Middle East following the joint U.S.-Israeli military campaign against the country in late February 2026. The activity, besides embracing previously undocumented techniques and enhanced capabilities, is characterized by the use of a new backdoor codenamed MiniFast (aka MiniUpdate) that appears to have been developed with assistance using artificial intelligence (AI), Check Point said in an analysis published last week. Affiliated with Iran's Islamic Revolutionary Guard Corps (IRGC), Nimbus Manticore is best known for targeting defense, aviation, and telecommunication sectors using career-themed phishing lures. These campaigns have also been codenamed the Iranian Dream Job, owing to tactical similarities with Operation Dream...

KnowledgeDeliver LMS Flaw Exploited to Deploy Godzilla and Cobalt Strike

May 26, 2026 Vulnerability / Threat Intelligence
A now-patched high-severity security flaw affecting Digital Knowledge KnowledgeDeliver , a Learning Management System (LMS) popular in Japan, was exploited as a zero-day to deliver the Godzilla web shell and ultimately facilitate the deployment of Cobalt Strike Beacon. The vulnerability, tracked as CVE-2026-5426 (CVSS score: 7.5), stems from the use of hard-coded ASP.NET machine keys, leading to unauthenticated remote code execution via a ViewState deserialization attack. The abuse of publicly disclosed ASP.NET machine keys by threat actors was first documented by Microsoft in February 2025. "An unknown threat actor leveraged this access to inject malicious code into the LMS platform, with the goal of infecting users visiting the site," Google Mandiant and Google Threat Intelligence Group (GTIG) said . The security flaw impacted Digital Knowledge KnowledgeDeliver deployments prior to February 24, 2026. It's worth noting that similar vulnerabilities in Sitecore Ex...

⚡ Weekly Recap: Linux Flaws, Defender 0-Days, Router Botnets, and Supply Chain Chaos

May 25, 2026 Cybersecurity / Hacking
Monday recap. Same mess, new week. A sketchy dev tool got people pwned, old bugs came back from the dead, and security products somehow needed protecting from themselves. A bunch of companies spent the week checking old boxes and forgotten servers they should've patched years ago. Good times. Phishing crews are getting smarter too - less obvious scam junk, more targeted stuff that actually looks real. Meanwhile, botnets are grabbing anything exposed to the internet like it's free candy. The Internet's still a dumpster fire. Let’s get into it. ⚡ Threat of the Week GitHub Breached via Nx Console VS Code Extension —GitHub officially confirmed that the breach of its internal repositories was the result of a compromise of an employee device involving a poisoned version of the Nx Console Microsoft Visual Studio Code (VS Code) extension. The attack is said to have allowed the threat actor, a cybercriminal group known as TeamPCP, to exfiltrate about 3,800 repositories. G...
Ghost CMS CVE-2026-26980 Exploited to Hijack 700+ Sites for ClickFix Attacks

Ghost CMS CVE-2026-26980 Exploited to Hijack 700+ Sites for ClickFix Attacks

May 25, 2026 Vulnerability / Web Security
Threat actors are exploiting a recently disclosed critical security flaw in Ghost CMS to inject malicious JavaScript code with an aim to fuel ClickFix attacks. According to QiAnXin XLab, the activity involves the exploitation of CVE-2026-26980 (CVSS score: 9.4), an SQL injection vulnerability in Ghost's Content API that could allow an unauthenticated attacker to read arbitrary data from the database. The security flaw was addressed in February 2026 in version 6.19.1. The vulnerability was discovered by Anthropic using Claude. What makes the vulnerability severe is that it allows an attacker to gain access to a site's admin API key without permission, granting them the ability to poison the site by injecting malicious code. The admin API key can be used to invoke the admin API and can directly modify articles published on the content management system. The threat actor leveraged the security flaw to "obtain the target site's Admin API Key without authorizati...
The Alert Firehose Finally Meets Its Match

The Alert Firehose Finally Meets Its Match

May 25, 2026 Agentic AI / Threat Detection
Ask a cybersecurity pro about Network Detection and Response (NDR) and you might still hear "Noisy," "Too much data." But ask the teams running NDR that includes agentic AI capabilities and you'll hear they're actually using it to catch threats earlier, triage faster, and chase fewer false positives. The old complaint lingers in part because reputations are sticky, and because NDR has evolved faster than the narrative. The origins of noise NDR deployments have always given analysts deep visibility into network traffic, encrypted session behavior, and protocol anomalies. But visibility often came as raw material, not finished intelligence. Some systems required extensive manual tuning during deployment to prevent SIEM overload. Organizations that couldn't invest that time (or didn't know how important it was) helped cement NDR's "alert firehose" or "noisy" reputation. NDR with agentic AI turns noise into narrative A...
Lazarus Deploys RemotePE Memory-Only RAT Against Financial and Crypto Firms

Lazarus Deploys RemotePE Memory-Only RAT Against Financial and Crypto Firms

May 25, 2026 Endpoint Security / Threat Intelligence
Cybersecurity researchers have shed light on a cross-platform malware called RemotePE that has been put to use by the North Korea-linked Lazarus Group in attacks targeting financial and cryptocurrency organizations. RemotePE, per NCC Group subsidiary Fox-IT, is part of a multi-stage attack chain that involves two loaders tracked as DPAPILoader and RemotePELoader. "DPAPILoader decrypts and loads RemotePELoader from disk using the Windows Data Protection API ( DPAPI )," security researchers Yun Zheng Hu and Mick Koomen said . "RemotePELoader beacons to a C2 server and waits until it receives the next stage: RemotePE, a RAT executed entirely in memory and never written to disk, leaving no filesystem artifacts." RemotePE was first highlighted by the security vendor in September 2025 in connection with an attack targeting an unnamed organization in the decentralized finance (DeFi) sector, leading to the deployment of three malware families, including PondRAT, Th...
