Identity Security | Breaking Cybersecurity News | The Hacker News

The cybersecurity industry has spent the last several years chasing sophisticated threats like zero-days, supply chain compromises, and AI-generated exploits. However, the most reliable entry point for attackers still hasn't changed: stolen credentials. Identity-based attacks remain a dominant initial access vector in breaches today. Attackers obtain valid credentials through credential stuffing from prior breach databases, password spraying against exposed services, or phishing campaigns — and use them to walk through the front door. No exploits needed. Just a valid username and password. What makes this difficult to defend against is how unremarkable the initial access looks. A successful login from a legitimate credential doesn't trigger the same alarms as a port scan or a malware callback. The attacker looks like an employee. Once inside, they dump and crack additional passwords, reuse those credentials to move laterally, and expand their foothold across the environment....

Monday’s recap shows the same pattern in different places. A third-party tool becomes a way in, then leads to internal access. A trusted download path is briefly swapped to deliver malware. Browser extensions act normally while pulling data and running code. Even update channels are used to push payloads. It’s not breaking systems—it’s bending trust. There’s also a shift in how attacks run. Slower check-ins, multi-stage payloads, andmore code kept in memory. Attackers lean on real tools and normal workflows instead of custom builds. Some cases hint at supply-chain spread, where one weak link reaches further than expected. Go through the whole recap. The pattern across access, execution, and control only shows up when you see it all together. ⚡ Threat of the Week Vercel Discloses Data Breach —Web infrastructure provider Vercel has disclosed a security breach that allows bad actors to gain unauthorized access to "certain" internal Vercel systems. The incident originated f...

Monday is back, and the weekend’s backlog of chaos is officially hitting the fan. We are tracking a critical zero-day that has been quietly living in your PDFs for months, plus some aggressive state-sponsored meddling in infrastructure that is finally coming to light. It is one of those mornings where the gap between a quiet shift and a full-blown incident response is basically non-existent. The variety this week is particularly nasty. We have AI models being turned into autonomous exploit engines, North Korean groups playing the long game with social engineering, and fileless malware hitting enterprise workflows. There is also a major botnet takedown and new research proving that even fiber optic cables can be used to eavesdrop on your private conversations. Skim this before your next meeting. Let’s get into it. ⚡ Threat of the Week Adobe Acrobat Reader 0-Day Under Attack   — Adobe released emergency updates to fix a critical...

Anthropic restricted its Mythos Preview model last week after it autonomously found and exploited zero-day vulnerabilities in every major operating system and browser. Palo Alto Networks' Wendi Whitmore warned that similar capabilities are weeks or months from proliferation. CrowdStrike's 2026 Global Threat Report puts average eCrime breakout time at 29 minutes. Mandiant's M-Trends 2026 shows adversary hand-off times have collapsed to 22 seconds.  Offense is getting faster. The question is where exactly defenders are slow — because it's not where most SOC dashboards suggest. Detection tooling has gotten materially better. EDR, cloud security, email security, identity, and SIEM platforms ship with built-in detection logic that pushes MTTD close to zero for known techniques. That's real progress, and it's the result of years of investment in detection engineering across the industry.  But when adversaries are operating on timelines measured in s...

While much of the discussion on AI security centers around protecting ‘shadow’ AI and GenAI consumption, there's a wide-open window nobody's guarding: AI browser extensions.  A  new report from LayerX exposes just how deep this blind spot goes, and why AI extensions may be the most dangerous AI threat surface in your network that isn't on anyone's radar. AI browser extensions don't trigger your DLP and don't show up in your SaaS logs. They live inside the browser itself, with direct access to everything your employees see, type, and stay logged into. AI extensions are 60% more likely to have a vulnerability than extensions on average, are 3 times more likely to have access to cookies, 2.5 times more likely to be able to execute remote scripts in the browser, and 6 times more likely to have increased their permissions in the past year. These extensions install in seconds and can remain...

When talking about credential security, the focus usually lands on breach prevention. This makes sense when IBM’s 2025 Cost of a Data Breach Report puts the average cost of a breach at $4.4 million. Avoiding even one major incident is enough to justify most security investments, but that headline figure obscures the more persistent problems caused by recurring credential incidents. Account lockouts and compromised credentials don’t make the news. They show up as repeated helpdesk tickets, interrupted workflows, and time pulled away from higher-value work. Individually, each incident seems minor, but collectively they place a constant burden on IT teams and the wider business. The real cost doesn’t just sit in the breach you might prevent, but in the day-to-day disruption you’re already dealing with. Repeated incidents equal repeated costs If an organization finds itself suffering from credential-based attacks or repeated account c...

This week had real hits. The key software got tampered with. Active bugs showed up in the tools people use every day. Some attacks didn’t even need much effort because the path was already there. One weak spot now spreads wider than before. What starts small can reach a lot of systems fast. New bugs, faster use, less time to react. That’s this week. Read through it. ⚡ Threat of the Week Axios npm Package Compromised by N. Korean Hackers —Threat actors with ties to North Korea seized control of the npm account belonging to the lead maintainer of Axios, a popular npm package with nearly 100 million weekly downloads, to push malicious versions containing a cross-platform malware dubbed WAVESHAPER.V2. The activity has been attributed to a financially motivated threat actor known as UNC1069. The incident demonstrates how quickly the compromise of a popular npm package can have ripple effects through the ecosystem. T...

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)...

Unmasking impostors is something the art world has faced for decades, and there are valuable lessons from the works of Elmyr de Hory that can apply to the world of defensive cybersecurity. During the 1960s, de Hory gained infamy as a premier forger, passing off counterfeit masterworks of Picasso, Matisse, and Renoir to unsuspecting collectors and renowned museums. Over the next several decades, more than a thousand of his works slipped past experts who relied on trusted signatures, familiar patterns, and reputable provenance. It’s not unlike the challenges SOCs are facing now. We’re firmly in the Age of Imitation. Cyberattackers, equipped with AI, are mastering the art of imitating the familiar, posing as trusted users and masking their activity within legitimate processes and ordinary network traffic. As history shows, it’s often easier to identify impostors when you know what to look for. Key takeaways for defenders: Mimicry is the new normal: 81% of attacks are malware-free Ag...

Cybersecurity researchers are calling attention to an active device code phishing campaign that's targeting Microsoft 365 identities across more than 340 organizations in the U.S., Canada, Australia, New Zealand, and Germany. The activity, per Huntress, was first spotted on February 19, 2026, with subsequent cases appearing at an accelerated pace since then. Notably, the campaign leverages Cloudflare Workers redirects with captured sessions redirected to infrastructure hosted on a platform-as-a-service (PaaS) offering called Railway, effectively turning it into a credential harvesting engine. Construction, non-profits, real estate, manufacturing, financial services, healthcare, legal, and government are some of the prominent sectors targeted as part of the campaign.  "What also makes this campaign unusual is not just the device code phishing techniques involved, but the variety of techniques observed," the company said. "Construction bid lures, landing page code...

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, ...

Microsoft has warned of fresh campaigns that are capitalizing on the upcoming tax season in the U.S. to harvest credentials and deliver malware. The email campaigns take advantage of the urgency and time-sensitive nature of emails to send phishing messages masquerading as refund notices, payroll forms, filing reminders, and requests from tax professionals to deceive recipients into opening malicious attachments, scanning QR code, or interacting with suspicious links. "Many campaigns target individuals for personal and financial data theft, but others specifically target accountants and other professionals who handle sensitive documents, have access to financial data, and are accustomed to receiving tax-related emails during this period," the Microsoft Threat Intelligence and Microsoft Defender Security Research teams said in a report published last week. While some of these efforts direct users to sketchy pages designed through Phishing-as-a-service (PhaaS) platforms, ot...

Artificial Intelligence (AI) is changing how individuals and organizations conduct many activities, including how cybercriminals carry out phishing attacks and iterate on malware. Now, cybercriminals are using AI to generate personalized phishing emails, deepfakes and malware that evade traditional detection by impersonating normal user activity and bypassing legacy security models. As a result, rule-based models alone are often insufficient for identity security against AI-enabled threats. Behavioral analytics must evolve beyond monitoring suspicious activity patterns over time into dynamic, identity-based risk modeling capable of identifying inconsistencies in real time. Common risks introduced by AI-enabled attacks AI-enabled cyber attacks introduce very different security risks compared to traditional cyber threats. By relying on automation and mimicking legitimate behavior, AI allows cybercriminals to scale their attacks while reducing obvious signals to remain undetected. AI-...

Security teams today are not short on tools or data. They are overwhelmed by both.  Yet within the terabytes of alerts, exposures, and misconfigurations – security teams still struggle to understand context:  Q: Which exposures, misconfigurations, and vulnerabilities chain together to create viable attack paths to crown jewels? Even the most mature security teams can’t answer that easily. The problem isn't the tools. It's that the tools don’t talk to each other.  This is precisely the problem Gartner's Cybersecurity Mesh Architecture (CSMA) framework was designed to solve – and it's what Mesh Security has operationalized with the world's first purpose-built CSMA platform. In this article, we’ll walk through what CSMA is and how Mesh CSMA:  Discovers attack paths to crown jewels Prioritizes based on active threats  Eliminates attack paths systematically What Is CSMA, and Why Does It Matter Now? Before we dive into the platform, let’s clarify what C...

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...

If you run security at any reasonably complex organization, your validation stack probably looks something like this: a BAS tool in one corner. A pentest engagement, or maybe an automated pentesting product, in another. A vulnerability scanner feeding an attack surface management platform somewhere else. Each tool gives you a slice of the picture. None of them talks to each other in any meaningful way. Meanwhile, adversaries do not attack in silos. A real intrusion might chain together an exposed identity, a cloud misconfiguration, a missed detection opportunity, and an unpatched vulnerability in a single operation. Attackers understand that your environment is an interconnected system. Unfortunately, most validation programs are still treating it as a set of disparate, disconnected parts. This isn't a minor inefficiency. It's a structural blind spot. And it's lasted for years because the market has treated every validation discipline as a separate category, with its own...

Phishing has quietly turned into one of the hardest enterprise threats to expose early. Instead of crude lures and obvious payloads, modern campaigns rely on trusted infrastructure, legitimate-looking authentication flows, and encrypted traffic that conceals malicious behavior from traditional detection layers. For CISOs, the priority is now clear: scale phishing detection in a way that helps the SOC uncover real risk before it becomes credential theft, business interruption, and board-level fallout. Why Scaling Phishing Detection Has Become a Priority for Modern SOCs For many security teams, phishing is no longer a single alert to investigate — it is a continuous stream of suspicious links, login attempts, and user-reported messages that must be validated quickly. The problem is that most SOC workflows were never designed to handle this volume. Each investigation still requires time, context gathering, and manual validation, while attackers operate at machine speed. When phishing ...

Salesforce has warned of an increase in threat actor activity that's aimed at exploiting misconfigurations in publicly accessible Experience Cloud sites by making use of a customized version of an open-source tool called AuraInspector. The activity, per the company, involves the exploitation of customers' overly permissive Experience Cloud guest user configurations to obtain access to sensitive data. "Evidence indicates the threat actor is leveraging a modified version of the open-source tool AuraInspector [...] to perform mass scanning of public-facing Experience Cloud sites," Salesforce said . "While the original AuraInspector is limited to identifying vulnerable objects by probing API endpoints that these sites expose (specifically the /s/sfsites/aura endpoint), the actor has developed a custom version of the tool capable of going beyond identification to actually extract data — exploiting overly permissive guest user settings." AuraInspector ref...

The North Korean threat actor known as UNC4899 is suspected to be behind a sophisticated cloud compromise campaign targeting a cryptocurrency organization in 2025 to steal millions of dollars in cryptocurrency. The activity has been attributed with moderate confidence to the state-sponsored adversary, which is also tracked under the cryptonyms Jade Sleet, PUKCHONG, Slow Pisces, and TraderTraitor.  "This incident is notable for its blend of social engineering, exploitation of personal-to-corporate device peer-to-peer data (P2P) transfer mechanisms, workflows, and eventual pivot to the cloud to employ living-off-the-cloud (LOTC) techniques," the tech giant noted in its H1 2026 Cloud Threat Horizons Report shared with The Hacker News. Upon gaining access to the cloud environment, the attackers are said to have abused legitimate DevOps workflows to harvest credentials, break out of the confines of containers, and tamper with Cloud SQL databases to facilitate the cryptocu...

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...
