CrowdStrike, in partnership with Google and the Shadowserver Foundation, has announced the simultaneous disruption of all command-and-control (C2) channels associated with GlassWorm , a persistent software chain campaign targeting software developers through malicious packages and extensions. "Since at least early 2025, GlassWorm operators have systematically targeted software developers, a population with access to source code repositories, cloud platforms, CI/CD pipelines, and package registries," CrowdStrike said . The development comes as developers have increasingly become lucrative targets for pulling off software supply chain attacks, enabling attackers to leverage a single compromised workstation to impact thousands of downstream organizations and users at once. GlassWorm, since its emergence last year, has conducted a "multi-pronged campaign" using trojanized VS Code extensions published on both the Microsoft VS Code Marketplace and Open VSX, ther...

Most organizations still picture cyber defense as a fortress problem: build stronger walls, add more guards, buy another detection engine. But modern incidents rarely crash through the front gate. They drift in disguised as routine activity, hide inside legitimate processes, and quietly accumulate risk long before anyone labels them an "incident." That changes the role of the SOC entirely. The best SOCs today are not simply detecting attacks. They are reducing the amount of uncertainty the business can accumulate. Every unidentified process, every unenriched alert, every delayed investigation becomes operational debt that compounds silently until it erupts into downtime, compliance issues, customer impact, or reputational damage. Prevention, then, is no longer about blocking everything at the perimeter. It is about shrinking the time between "something changed" and "we understand exactly what it means." That requires three things: continuous...

Cybersecurity researchers have disclosed a security flaw in Gitea, an open-source, self-hosted platform for version control, that allows unauthenticated remote attackers to pull private container images from Gitea deployments without requiring an account, password, or other credentials. The vulnerability, tracked as CVE-2026-27771 (CVSS score: N/A), affects all versions of Gitea prior to 1.26.2 , which addresses the issue. According to Noscope, the security defect likely impacts more than 30,000 deployments across over 30 countries and went undetected for close to four years. The vast majority of the exposures are in China, the U.S., Germany, France, and the U.K. Affected organizations span healthcare providers, aerospace manufacturers, retail infrastructure, and internet service providers. "On affected versions, the private designation on a container repository did not deliver the protection operators reasonably expected it to," Noscope said . "Gitea's cont...

Microsoft has warned of an active cryptojacking campaign that makes use of artificial intelligence (AI) chatbot interactions as a mechanism for surfacing malicious download sites. "This emerging delivery technique extends social engineering beyond conventional search results and increases the visibility of malicious software recommendations," Microsoft Defender Experts and the Microsoft Defender Security Research Team said in a report published Tuesday. The activity, per the tech giant, impersonates legitimate system utilities like CrystalDiskInfo, HWMonitor, Display Driver Uninstaller, FurMark, K-Lite Codec Pack, and PDFgear, likely in an attempt to target users who own high-performance GPUs. The idea is to focus on compromising systems with higher mining value than indiscriminately infecting a large number of machines, it added. The goals of the campaign are not merely financially motivated. The threat actors have also been found to establish persistent remote acce...

The Iranian hacking group known as MuddyWater has been linked to a new campaign affecting at least nine organizations across nine countries on four continents in the first quarter of 2026. The activity targeted industrial and electronics manufacturing, education and public-sector bodies, financial services, and professional services, per the Threat Hunter Team from Symantec and Carbon Black. Among the victims is a major South Korean electronics manufacturer, with the attackers spending a week inside its network in February 2026. Also singled as part of the sprawling espionage effort were an international airport in the Middle East, Southeast Asian industrial manufacturers, and a Latin American financial-services provider. "The attackers relied heavily on DLL side-loading using legitimately signed Fortemedia (fmapp.exe) and SentinelOne (sentinelmemoryscanner.exe) binaries to execute malicious DLLs while masquerading as benign software," Broadcom's cybersecurity t...

Every single day, hackers are finding new ways to crash websites and steal data. But right now, something has changed. Hackers are no longer working alone. They are now using powerful Artificial Intelligence (AI) tools to make their attacks faster, stronger, and much harder to stop. According to recent updates from The Hacker News , bad actors are using AI to find weak spots in systems and launch massive "DDoS attacks" that can take your business offline in seconds. If your website goes down, you lose money, you lose customer trust, and you spend days trying to fix the mess. 👉 Save Your Free Webinar Seat The Old Way of Protection Doesn't Work Anymore In the past, you could set up a simple firewall, update your software, and feel safe. Not anymore. AI-assisted attacks can think and adapt. They don't just hit your front door; they look for hidden entry points, smart APIs, and tiny mistakes in your cloud setup. They do in minutes what used to take human h...

Microsoft has rolled out updates to fix a remote code execution vulnerability impacting SharePoint that could be exploited by bad actors in attacks without requiring any specialized conditions to be met. The vulnerability, tracked as CVE-2026-45659 , carries a CVSS score of 8.8. It has been assigned an important severity. "Deserialization of untrusted data in Microsoft Office SharePoint allows an authorized attacker to execute code over a network," Microsoft said in an advisory released last week. Microsoft noted that the vulnerability could be triggered by any authenticated attacker, and that it does not require administrator or other elevated privileges. "In a network-based attack, an authenticated attacker, who has a minimum of Site Member permissions (PR:L), could execute code remotely on the SharePoint Server," the Windows maker added. Microsoft credited a researcher named MEOW for discovering and reporting the flaw. Updates have been released for th...

Multi-factor authentication (MFA) was supposed to close a critical gap in identity security. It meant that, even if an attacker possessed the account credentials, they couldn't log in without the second factor. While that logic was sound, attackers have now figured out that they don't need to steal the second factor: they just need the user to hand it over. If your workforce authenticates with push-based MFA, this attack is a live threat to your organization today. Tools like Specops Secure Access are built specifically to close that gap, but before getting into the fix, it's worth understanding how this technique works. How MFA prompt bombing works The attack requires three key elements to work: Valid account credentials, usually sourced from breached password dumps on the dark web A login portal that uses push-based MFA (such as a VPN, Microsoft 365, Okta, or Duo) A victim who is alerted every time the attacker tries the login Attackers repeatedly tri...

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...

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...

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...

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...
