Until recently, the cyber attacker methodology behind the biggest breaches of the last decade or so has been pretty consistent: Compromise an endpoint via software exploit, or social engineering a user to run malware on their device;  Find ways to move laterally inside the network and compromise privileged identities; Repeat as needed until you can execute your desired attack — usually stealing data from file shares, deploying ransomware, or both.  But attacks have fundamentally changed as networks have evolved. With the SaaS-ification of enterprise IT, core business systems aren't locally deployed and centrally managed in the way they used to be. Instead, they're logged into over the internet, and accessed via a web browser. Attacks have shifted from targeting local networks to SaaS services, accessed through employee web browsers. Under the shared responsibility model, the part that's left to the business consuming a SaaS service is mostly constrained to how they ma...

Attacks that target users in their web browsers have seen an unprecedented rise in recent years. In this article, we'll explore what a "browser-based attack" is, and why they're proving to be so effective.  What is a browser-based attack? First, it's important to establish what a browser-based attack is. In most scenarios, attackers don't think of themselves as attacking your web browser. Their end-goal is to compromise your business apps and data. That means going after the third-party services that are now the backbone of business IT. The most common attack path today sees attackers log into third-party services, dump the data, and monetize it through extortion. You need only look at last year's Snowflake customer breaches or the still-ongoing Salesforce attacks to see the impact.  The most logical way to do this is by targeting users of those apps. And because of the changes to working practices, your users are more accessible than ever to external attackers — and ex...

ClickFix, FileFix, fake CAPTCHA — whatever you call it, attacks where users interact with malicious scripts in their web browser are a fast-growing source of security breaches.  ClickFix attacks prompt the user to solve some kind of problem or challenge in the browser — most commonly a CAPTCHA, but also things like fixing an error on a webpage.  The name is a little misleading, though — the key factor in the attack is that they trick users into running malicious commands on their device by copying malicious code from the page clipboard and running it locally. Examples of ClickFix lures used by attackers in the wild. ClickFix is known to be regularly used by the Interlock ransomware group and other prolific threat actors, including state-sponsored APTs. A number of recent public data breaches have been linked to ClickFix-style TTPs, such as Kettering Health, DaVita, City of St. Paul, Minnesota, and the Texas Tech University Health Sciences Centers (with many more breaches ...

Phishing attacks are no longer confined to the email inbox, with 1 in 3 phishing attacks now taking place over non-email channels like social media, search engines, and messaging apps. LinkedIn in particular has become a hotbed for phishing attacks, and for good reason. Attackers are running sophisticated spear-phishing attacks against company executives, with recent campaigns seen targeting enterprises in financial services and technology verticals.  But phishing outside of email remains severely underreported — not exactly surprising when we consider that most of the industry's phishing metrics come from email security tools. Your initial thought might be "why do I care about employees getting phished on LinkedIn?" Well, while LinkedIn is a personal app, it's routinely used for work purposes, accessed from corporate devices, and attackers are specifically targeting business accounts like Microsoft Entra and Google Workspace. So, LinkedIn phishing is a key threat that busi...

Security, trust, and stability — once the pillars of our digital world — are now the tools attackers turn against us. From stolen accounts to fake job offers, cybercriminals keep finding new ways to exploit both system flaws and human behavior. Each new breach proves a harsh truth: in cybersecurity, feeling safe can be far more dangerous than being alert. Here's how that false sense of security was broken again this week. ⚡ Threat of the Week Newly Patched Critical Microsoft WSUS Flaw Comes Under Attack — Microsoft released out-of-band security updates to patch a critical-severity Windows Server Update Service (WSUS) vulnerability that has since come under active exploitation in the wild. The vulnerability in question is CVE-2025-59287 (CVSS score: 9.8), a remote code execution flaw in WSUS that was originally fixed by the tech giant as part of its Patch Tuesday update published last week. According to Eye Security and Huntress, the security flaw is being weaponized to drop a .N...

A quiet tweak in a popular open-source tool opened the door to a supply chain breach—what started as a targeted attack quickly spiraled, exposing secrets across countless projects. That wasn't the only stealth move. A new all-in-one malware is silently stealing passwords, crypto, and control—while hiding in plain sight. And over 300 Android apps joined the chaos, running ad fraud at scale behind innocent-looking icons. Meanwhile, ransomware gangs are getting smarter—using stolen drivers to shut down defenses—and threat groups are quietly shifting from activism to profit. Even browser extensions are changing hands, turning trusted tools into silent threats. AI is adding fuel to the fire—used by both attackers and defenders—while critical bugs, cloud loopholes, and privacy shakeups are keeping teams on edge. Let's dive into the threats making noise behind the scenes. ⚡ Threat of the Week Coinbase the Initial Target of GitHub Action Supply Chain Breach — The supply chain compromise...

A new multi-stage malware campaign is targeting Minecraft users with a Java-based malware that employs a distribution-as-service (DaaS) offering called Stargazers Ghost Network . "The campaigns resulted in a multi-stage attack chain targeting Minecraft users specifically," Check Point researchers Jaromír Hořejší and Antonis Terefos said in a report shared with The Hacker News. "The malware was impersonating Oringo and Taunahi, which are 'Scripts and macros tools' (aka cheats). Both the first and second stages are developed in Java and can only be executed if the Minecraft runtime is installed on the host machine." The end goal of the attack is to trick players into downloading a Minecraft mod from GitHub and deliver a .NET information stealer with comprehensive data theft capabilities. The campaign was first detected by the cybersecurity company in March 2025. What makes the activity notable is its use of an illicit offering called the Stargazers Ghost...

Not every risk looks like an attack. Some problems start as small glitches, strange logs, or quiet delays that don't seem urgent—until they are. What if your environment is already being tested, just not in ways you expected? Some of the most dangerous moves are hidden in plain sight. It's worth asking: what patterns are we missing, and what signals are we ignoring because they don't match old playbooks? This week's reports bring those quiet signals into focus—from attacks that bypassed MFA using trusted tools, to supply chain compromises hiding behind everyday interfaces. Here's what stood out across the cybersecurity landscape: ⚡ Threat of the Week Cloudflare Blocks Massive 7.3 Tbps DDoS Attack — Cloudflare said it autonomously blocked the largest distributed denial-of-service (DDoS) attack ever recorded, which hit a peak of 7.3 terabits per second (Tbps). The attack, the company said, targeted an unnamed hosting provider and delivered 37.4 terabytes in 45 seconds. It origi...

Power doesn't just disappear in one big breach. It slips away in the small stuff—a patch that's missed, a setting that's wrong, a system no one is watching. Security usually doesn't fail all at once; it breaks slowly, then suddenly. Staying safe isn't about knowing everything—it's about acting fast and clear before problems pile up. Clarity keeps control. Hesitation creates risk. Here are this week's signals—each one pointing to where action matters most. ⚡ Threat of the Week Ghost Tap NFC-Based Mobile Fraud Takes Off — A new Android trojan called PhantomCard has become the latest malware to abuse near-field communication (NFC) to conduct relay attacks for facilitating fraudulent transactions in attacks targeting banking customers in Brazil. In these attacks, users who end up installing the malicious apps are instructed to place their credit/debit card on the back of the phone to begin the verification process, only for the card data to be sent to an attacker-controlled NFC relay...

In what's the latest instance of a software supply chain attack, unknown threat actors managed to compromise Toptal's GitHub organization account and leveraged that access to publish 10 malicious packages to the npm registry. The packages contained code to exfiltrate GitHub authentication tokens and destroy victim systems, Socket said in a report published last week. In addition, 73 repositories associated with the organization were made public. The list of affected packages is below - @toptal/picasso-tailwind @toptal/picasso-charts @toptal/picasso-shared @toptal/picasso-provider @toptal/picasso-select @toptal/picasso-quote @toptal/picasso-forms @xene/core @toptal/picasso-utils @toptal/picasso-typograph All the Node.js libraries were embedded with identical payloads in their package.json files, attracting a total of about 5,000 downloads before they were removed from the repository. The nefarious code has been found to specifically target the preinstall and p...
