There is a character that keeps appearing in enterprise security departments, and most CISOs know exactly who that is. It doesn’t build. It doesn’t enable. Its entire function is to say "No." No to ChatGPT. No to DeepSeek. No to the file-sharing tool the product team swears by. For years, this looked like security. But in 2026, "Doctor No" is no longer just a management headache – it is a systemic security liability. Because when you block the work, users don’t stop. They reroute. The Tax-Evaders of Productivity When security feels like a tax on efficiency, employees find a way to "evade" it. The industry has long relied on Endpoint Agents to enforce control. But as any CISO knows, these agents come with a heavy "tax." They hook into the OS kernel, they’re invasive, they notoriously break during macOS updates, and they make high-performance machines run hot. The result? Users find workarounds. Files move into personal Gmail. Prompts are...

Google on Thursday released security updates for its Chrome web browser to address 21 vulnerabilities, including a zero-day flaw that it said has been exploited in the wild. The high-severity vulnerability, CVE-2026-5281 (CVSS score: N/A), concerns a use-after-free bug in Dawn , an open-source and cross-platform implementation of the WebGPU standard. "Use-after-free in Dawn in Google Chrome prior to 146.0.7680.178 allowed a remote attacker who had compromised the renderer process to execute arbitrary code via a crafted HTML page," according to a description of the flaw in the NIST's National Vulnerability Database (NVD). As is customary for these alerts, Google did not provide any further details on how the shortcoming is being exploited and who may be behind the effort. This is typically done so as to ensure that a majority of users are updated with a fix and prevent other actors from joining the exploitation bandwagon. "Google is aware that an exploit for C...

A new campaign has leveraged the ClickFix social engineering tactic as a way to distribute a previously undocumented malware loader referred to as DeepLoad . "It likely uses AI-assisted obfuscation and process injection to evade static scanning, while credential theft starts immediately and captures passwords and sessions even if the primary loader is blocked," ReliaQuest researchers Thassanai McCabe and Andrew Currie said in a report shared with The Hacker News. The starting point of the attack chain is a ClickFix lure that tricks users into running PowerShell commands by pasting the command into the Windows Run dialog under the pretext of addressing a non-existent issue. This, in turn, uses "mshta.exe," a legitimate Windows utility to download and run an obfuscated PowerShell loader. The loader, for its part, has been found to conceal its actual functionality among meaningless variable assignments, likely in an attempt to deceive security tools. It's ass...

Some weeks are loud. This one was quieter but not in a good way. Long-running operations are finally hitting courtrooms, old attack methods are showing up in new places, and research that stopped being theoretical right around the time defenders stopped paying attention. There's a bit of everything this week. Persistence plays, legal wins, influence ops, and at least one thing that looks boring until you see what it connects to. All of it below. Let's go. ⚡ Threat of the Week Citrix Flaw Comes Under Active Exploitation — A critical security flaw in Citrix NetScaler ADC and NetScaler Gateway (CVE-2026-3055, CVSS score: 9.3) has come under active exploitation as of March 27, 2026. The vulnerability refers to a case of insufficient input validation leading to memory overread, which an attacker could exploit to leak potentially sensitive information. Per Citrix, successful exploitation of the flaw hinges on the appliance being configured as a SAML Identity Provider (SAML IDP)...

Cybersecurity researchers have disclosed a vulnerability in Anthropic's Claude Google Chrome Extension that could have been exploited to trigger malicious prompts simply by visiting a web page. The flaw "allowed any website to silently inject prompts into that assistant as if the user wrote them," Koi Security researcher Oren Yomtov said in a report shared with The Hacker News. "No clicks, no permission prompts. Just visit a page, and an attacker completely controls your browser." The issue, codenamed ShadowPrompt , chains two underlying flaws: An overly permissive origin allowlist in the extension that allowed any subdomain matching the pattern (*.claude.ai) to send a prompt to Claude for execution. A document object model ( DOM )-based cross-site scripting ( XSS ) vulnerability in an Arkose Labs CAPTCHA component hosted on "a-cdn.claude[.]ai." Specifically, the XSS vulnerability enables the execution of arbitrary JavaScript code in the cont...

Cybersecurity researchers have flagged a new evolution of the GlassWorm campaign that delivers a multi-stage framework capable of comprehensive data theft and installing a remote access trojan (RAT), which deploys an information-stealing Google Chrome extension masquerading as an offline version of Google Docs. "It logs keystrokes, dumps cookies and session tokens, captures screenshots, and takes commands from a C2 server hidden in a Solana blockchain memo," Aikido security researcher Ilyas Makari said in a report published last week. GlassWorm is the moniker assigned to a persistent campaign that obtains an initial foothold through rogue packages published across npm, PyPI, GitHub, and the Open VSX marketplace. In addition, the operators are known to compromise the accounts of project maintainers to push poisoned updates. The attacks are careful enough to avoid infecting systems with a Russian locale and use Solana transactions as a dead drop resolver to fetch the com...

Another week, another reminder that the internet is still a mess. Systems people thought were secure are being broken in simple ways, showing many still ignore basic advisories. This edition covers a mix of issues: supply chain attacks hitting CI/CD setups, long-abused IoT devices being shut down, and exploits moving quickly from disclosure to real attacks. There are also new malware tricks showing attackers are becoming more patient and creative. It’s a mix of old problems that never go away and new methods that are harder to detect. There are quiet state-backed activities, exposed data from open directories, growing mobile threats, and a steady stream of zero-days and rushed patches. Grab a coffee, and at least skim the CVE list. Some of these are the kind you don’t want to discover after the damage is done. ⚡ Threat of the Week Trivy Vulnerability Scanner Breached in for Supply Chain Attack — Attackers have backdoored the widely used open-source Trivy vulnerability scanner, ...

Apple on Tuesday released its first round of Background Security Improvements to address a security flaw in WebKit that affects iOS, iPadOS, and macOS. The vulnerability, tracked as CVE-2026-20643 (CVSS score: N/A), has been described as a cross-origin issue in WebKit's Navigation API that could be exploited to bypass the same-origin policy when processing maliciously crafted web content. The flaw affects iOS 26.3.1, iPadOS 26.3.1, macOS 26.3.1, and macOS 26.3.2. It has been addressed with improved input validation in iOS 26.3.1 (a), iPadOS 26.3.1 (a), macOS 26.3.1 (a), and macOS 26.3.2 (a). Security researcher Thomas Espach has been credited with discovering and reporting the shortcoming. Apple notes that Background Security Improvements are meant for delivering lightweight security releases for components such as the Safari browser, WebKit framework stack, and other system libraries through smaller, ongoing security patches rather than issuing them as part of larger softwa...

Some weeks in security feel normal. Then you read a few tabs and get that immediate “ah, great, we’re doing this now” feeling. This week has that energy. Fresh messes, old problems getting sharper, and research that stops feeling theoretical real fast. A few bits hit a little too close to real life, too. There’s a good mix here: weird abuse of trusted stuff, quiet infrastructure ugliness, sketchy chatter, and the usual reminder that attackers will use anything that works. Scroll on. You’ll see what I mean. ⚡ Threat of the Week Google Patches 2 Actively Exploited Chrome 0-Days — Google released security updates for its Chrome web browser to address two high-severity vulnerabilities that it said have been exploited in the wild. The vulnerabilities related to an out-of-bounds write vulnerability in the Skia 2D graphics library (CVE-2026-3909) and an inappropriate implementation vulnerability in the V8 JavaScript and WebAssembly engine (CVE-2026-3910) that could result in out-of-boun...

Ukrainian entities have emerged as the target of a new campaign likely orchestrated by threat actors linked to Russia, according to a report from S2 Grupo's LAB52 threat intelligence team. The campaign, observed in February 2026, has been assessed to share overlaps with a prior campaign mounted by Laundry Bear (aka UAC-0190 or Void Blizzard) aimed at Ukrainian defense forces with a malware family known as PLUGGYAPE. The attack activity "employs various judicial and charity themed lures to deploy a JavaScript‑based backdoor that runs through the Edge browser," the cybersecurity company said. Codenamed DRILLAPP , the malware is capable of uploading and downloading files, leveraging the microphone, and capturing images through the webcam by taking advantage of the web browser's features. Two different versions of the campaign have been identified, with the first iteration detected in early February. The attack makes use of a Windows shortcut (LNK) file to create...

Google on Thursday released security updates for its Chrome web browser to address two high-severity vulnerabilities that it said have been exploited in the wild. The list of vulnerabilities is as follows - CVE-2026-3909 (CVSS score: 8.8) - An out-of-bounds write vulnerability in the Skia 2D graphics library that allows a remote attacker to perform out-of-bounds memory access via a crafted HTML page. CVE-2026-3910 (CVSS score: 8.8) - An inappropriate implementation vulnerability in the V8 JavaScript and WebAssembly engine that allows a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. Both vulnerabilities were discovered and reported by Google itself on March 10, 2026. As is customary in these cases, no details are available about how the issues are being abused in the wild and who is behind the efforts. This is done so as to prevent other threat actors from exploiting the issues. "Google is aware that exploits for both CVE-2026-3909 an...

Agentic web browsers that leverage artificial intelligence (AI) capabilities to autonomously execute actions across multiple websites on behalf of a user could be trained and tricked into falling prey to phishing and scam traps. The attack, at its core, takes advantage of AI browsers' tendency to reason their actions and use it against the model itself to lower their security guardrails, Guardio said in a report shared with The Hacker News ahead of publication. "The AI now operates in real time, inside messy and dynamic pages, while continuously requesting information, making decisions, and narrating its actions along the way. Well, 'narrating' is quite an understatement - It blabbers, and way too much!," security researcher Shaked Chen said. "This is what we call Agentic Blabbering : the AI Browser exposing what it sees, what it believes is happening, what it plans to do next, and what signals it considers suspicious or safe." By intercepting thi...

Another week in cybersecurity. Another week of "you've got to be kidding me." Attackers were busy. Defenders were busy. And somewhere in the middle, a whole lot of people had a very bad Monday morning. That's kind of just how it goes now. The good news? There were some actual wins this week. Real ones. The kind where the good guys showed up, did the work, and made a dent. It doesn't always happen, so when it does, it's worth noting. The bad news? For every win, there's a fresh headache waiting right behind it. New tricks, old tricks dressed up in new clothes, and a few things that'll make you want to go touch grass and never log back in. But you will. We all do. So here's everything that mattered this week — the wins, the warnings, and the stuff you really shouldn't ignore. ⚡ Threat of the Week Tycoon 2FA and LeakBase Operations Dismantled — The infrastructure hosting the Tycoon2FA service, which Europol said was among the largest advers...

Two Google Chrome extensions have turned malicious after what appears to be a case of ownership transfer , offering attackers a way to push malware to downstream customers, inject arbitrary code, and harvest sensitive data. The extensions in question, both originally associated with a developer named "akshayanuonline@gmail.com" (BuildMelon), are listed below - QuickLens - Search Screen with Google Lens (ID: kdenlnncndfnhkognokgfpabgkgehodd) - 7,000 users ShotBird - Scrolling Screenshots, Tweet Images & Editor (ID: gengfhhkjekmlejbhmmopegofnoifnjp) - 800 users While QuickLens is no longer available for download from the Chrome Web Store, ShotBird remains accessible as of writing. ShotBird was originally launched in November 2024, with its developer, Akshay Anu S (@AkshayAnuOnline), claiming on X that the extension is suitable for "creating professional, studio-like visuals," and that all processing happens locally. According to research published by mo...

Anthropic on Friday said it discovered 22 new security vulnerabilities in the Firefox web browser as part of a security partnership with Mozilla. Of these, 14 have been classified as high, seven have been classified as moderate, and one has been rated low in severity. The issues were addressed in Firefox 148 , released late last month. The vulnerabilities were identified over a two-week period in January 2026. The artificial intelligence (AI) company said the number of high-severity bugs identified by its Claude Opus 4.6 large language model (LLM) represents "almost a fifth" of all high-severity vulnerabilities that were patched in Firefox in 2025. Anthropic said the LLM detected a use-after-free bug in the browser's JavaScript after "just" 20 minutes of exploration, which was then validated by a human researcher in a virtualized environment to rule out the possibility of a false positive. "By the end of this effort, we had scanned nearly 6,000 C++ ...

Microsoft on Thursday disclosed details of a new widespread ClickFix social engineering campaign that has leveraged the Windows Terminal app as a way to activate a sophisticated attack chain and deploy the Lumma Stealer malware. The activity, observed in February 2026, makes use of the terminal emulator program instead of instructing users to launch the Windows Run dialog and paste a command into it. "This campaign instructs targets to use the Windows + X → I shortcut to launch Windows Terminal (wt.exe) directly, guiding users into a privileged command execution environment that blends into legitimate administrative workflows and appears more trustworthy to users," the Microsoft Threat Intelligence team said in a series of posts on X. What makes the latest variant notable is that it bypasses detections specifically designed to flag Run dialog abuse, not to mention take advantage of the legitimacy of Windows Terminal to trick unsuspecting users into running malicious ...

Google has announced a new program in its Chrome browser to ensure that HTTPS certificates are secure against the future risk posed by quantum computers . "To ensure the scalability and efficiency of the ecosystem, Chrome has no immediate plan to add traditional X.509 certificates containing post-quantum cryptography to the Chrome Root Store ," the Chrome Secure Web and Networking Team said . "Instead, Chrome, in collaboration with other partners, is developing an evolution of HTTPS certificates based on Merkle Tree Certificates (MTCs), currently in development in the PLANTS working group." As Cloudflare explains, MTC is a proposal for the next generation of the Public Key Infrastructure (PKI) used to secure the internet that aims to reduce the number of public keys and signatures in the TLS handshake to the bare minimum required. Under this model, a Certification Authority (CA) signs a single 'Tree Head' representing potentially millions of certi...

This week is not about one big event. It shows where things are moving. Network systems, cloud setups, AI tools, and common apps are all being pushed in different ways. Small gaps in access control, exposed keys, and normal features are being used as entry points. The pattern becomes clear only when you see everything together. Faster scans, smarter misuse of trusted services, and steady targeting of high-value sectors. Each story adds context. Reading them all gives a fuller picture of how today’s threat landscape is evolving. ⚡ Threat of the Week Cisco SD-WAN Zero-Day Exploited — A newly disclosed maximum-severity security flaw in Cisco Catalyst SD-WAN Controller (formerly vSmart) and Catalyst SD-WAN Manager (formerly vManage) has come under active exploitation in the wild as part of malicious activity that dates back to 2023. The vulnerability, tracked as CVE-2026-20127 (CVSS score: 10.0), allows an unauthenticated remote attacker to bypass authentication and obtain administr...

Security news rarely moves in a straight line. This week, it feels more like a series of sharp turns, some happening quietly in the background, others playing out in public view. The details are different, but the pressure points are familiar. Across devices, cloud services, research labs, and even everyday apps, the line between normal behavior and hidden risk keeps getting thinner. Tools meant to protect, update, or improve systems are also becoming pathways when something goes wrong. This recap gathers the signals in one place. Quick reads, real impact, and developments that deserve a closer look before they become next week’s bigger problem. ⚡ Threat of the Week Dell RecoverPoint for VMs Zero-Day Exploited — A maximum severity security vulnerability in Dell RecoverPoint for Virtual Machines has been exploited as a zero-day by a suspected China-nexus threat cluster dubbed UNC6201 since mid-2024. The activity involves the exploitation of CVE-2026-22769 (CVSS score: 10.0), a ca...

This week’s recap shows how small gaps are turning into big entry points. Not always through new exploits, often through tools, add-ons, cloud setups, or workflows that people already trust and rarely question. Another signal: attackers are mixing old and new methods. Legacy botnet tactics, modern cloud abuse, AI assistance, and supply-chain exposure are being used side by side, whichever path gives the easiest foothold. Below is the full weekly recap — a condensed scan of the incidents, flaws, and campaigns shaping the threat landscape right now. ⚡ Threat of the Week Malicious Outlook Add-in Turns Into Phishing Kit — In an unusual case of a supply chain attack, the legitimate AgreeTo add-in for Outlook has been hijacked and turned into a phishing kit that stole more than 4,000 Microsoft account credentials. This was made possible by seizing control of a domain associated with the now-abandoned project to serve a fake Microsoft login page. The incident demonstrates how overlooke...
