Microsoft on Tuesday shipped fixes to address a total of 78 security flaws across its software lineup, including a set of five zero-days that have come under active exploitation in the wild. Of the 78 flaws resolved by the tech giant, 11 are rated Critical, 66 are rated Important, and one is rated Low in severity. Twenty-eight of these vulnerabilities lead to remote code execution, 21 of them are privilege escalation bugs, and 16 others are classified as information disclosure flaws. The updates are in addition to eight more security defects patched by the company in its Chromium-based Edge browser since the release of last month's Patch Tuesday update . The five vulnerabilities that have come under active exploitation in the wild are listed below - CVE-2025-30397 (CVSS score: 7.5) - Scripting Engine Memory Corruption Vulnerability CVE-2025-30400 (CVSS score: 7.8) - Microsoft Desktop Window Manager (DWM) Core Library Elevation of Privilege Vulnerability CVE-2025-3270...

A new campaign is tricking users searching for the Meta Quest (formerly Oculus) application for Windows into downloading a new adware family called AdsExhaust. "The adware is capable of exfiltrating screenshots from infected devices and interacting with browsers using simulated keystrokes," cybersecurity firm eSentire said in an analysis, adding it identified the activity earlier this month. "These functionalities allow it to automatically click through advertisements or redirect the browser to specific URLs, generating revenue for the adware operators." The initial infection chain involves surfacing the bogus website ("oculus-app[.]com") on Google search results pages using search engine optimization (SEO) poisoning techniques, prompting unsuspecting site visitors to download a ZIP archive ("oculus-app.EXE.zip") containing a Windows batch script. The batch script is designed to fetch a second batch script from a command-and-control (C2) se...

Banking and logistics industries are under the onslaught of a reworked variant of a malware called  Chaes . "It has undergone major overhauls: from being rewritten entirely in Python, which resulted in lower detection rates by traditional defense systems, to a comprehensive redesign and an enhanced communication protocol," Morphisec said in a new detailed technical write-up shared with The Hacker News. Chaes, which first emerged in 2020, is known to target e-commerce customers in Latin America, particularly Brazil, to steal sensitive financial information. A subsequent analysis from Avast in early 2022  found  that the threat actors behind the operation, who call themselves Lucifer, had breached more than 800 WordPress websites to deliver Chaes to users of Banco do Brasil, Loja Integrada, Mercado Bitcoin, Mercado Livre, and Mercado Pago. Further updates were detected in December 2022, when Brazilian cybersecurity company Tempest Security Intelligence  uncovered...

This week, our news radar shows that every new tech idea comes with its own challenges. A hot AI tool is under close watch, law enforcement is shutting down online spots that help cybercriminals, and teams are busy fixing software bugs that could let attackers in. From better locks on our devices to stopping sneaky tricks online, simple steps are making a big difference.  Let's take a closer look at how these efforts are shaping a safer digital world. ⚡ Threat of the Week DeepSeek's Popularity Invites Scrutiny — The overnight popularity of DeepSeek, an artificial intelligence (AI) platform originating from China, has led to extensive scrutiny of its models, with several analyses finding ways to jailbreak its system and produce malicious or prohibited content. While jailbreaks and prompt injections are a persistent concern in mainstream AI products, the findings also show that the model lacks enough protections to prevent potential abuse by malicious actors . The AI chatbot ha...

This week has been crazy in the world of hacking and online security. From Thailand to London to the US, we've seen arrests, spies at work, and big power moves online. Hackers are getting caught. Spies are getting better at their jobs. Even simple things like browser add-ons and smart home gadgets are being used to attack people. Every day, there's a new story that shows how quickly things are changing in the fight over the internet. Governments are cracking down harder on cybercriminals. Big tech companies are rushing to fix their security. Researchers keep finding weak spots in apps and devices we use every day. We saw fake job recruiters on LinkedIn spying on people, huge crypto money-laundering cases, and brand-new malware made just to beat Apple's Mac protections. All these stories remind us: the same tech that makes life better can very easily be turned into a weapon. Here's a simple look at the biggest cybersecurity news happening right now — from the hidde...

Today, every unpatched system, leaked password, and overlooked plugin is a doorway for attackers. Supply chains stretch deep into the code we trust, and malware hides not just in shady apps — but in job offers, hardware, and cloud services we rely on every day. Hackers don't need sophisticated exploits anymore. Sometimes, your credentials and a little social engineering are enough. This week, we trace how simple oversights turn into major breaches — and the silent threats most companies still underestimate. Let's dive in. ⚡ Threat of the Week UNC5221 Exploits New Ivanti Flaw to Drop Malware — The China-nexus cyber espionage group tracked as UNC5221 exploited a now-patched flaw in Ivanti Connect Secure, CVE-2025-22457 (CVSS score: 9.0), to deliver an in-memory dropper called TRAILBLAZE, a passive backdoor codenamed BRUSHFIRE, and the SPAWN malware suite. The vulnerability was originally patched by Ivanti on February 11, 2025, indicating that the threat actors studied the patch a...

It's easy to think your defenses are solid — until you realize attackers have been inside them the whole time. The latest incidents show that long-term, silent breaches are becoming the norm. The best defense now isn't just patching fast, but watching smarter and staying alert for what you don't expect. Here's a quick look at this week's top threats, new tactics, and security stories shaping the landscape. ⚡ Threat of the Week F5 Exposed to Nation-State Breach — F5 disclosed that unidentified threat actors broke into its systems and stole files containing some of BIG-IP's source code and information related to undisclosed vulnerabilities in the product. The company said it learned of the incident on August 9, 2025, although it's believed that the attackers were in its network for at least 12 months. The attackers are said to have used a malware family called BRICKSTORM, which is attributed to a China-nexus espionage group dubbed UNC5221. GreyNoise said it observed elevat...

The first ThreatsDay Bulletin of 2026 lands on a day that already feels symbolic — new year, new breaches, new tricks. If the past twelve months taught defenders anything, it's that threat actors don't pause for holidays or resolutions. They just evolve faster. This week's round-up shows how subtle shifts in behavior, from code tweaks to job scams, are rewriting what "cybercrime" looks like in practice. Across the landscape, big players are being tested, familiar threats are mutating, and smaller stories are quietly signaling bigger patterns ahead. The trend isn't about one big breach anymore; it's about many small openings that attackers exploit with precision. The pace of exploitation, deception, and persistence hasn't slowed; it's only become more calculated. Each update in this edition highlights how the line between normal operations and compromise is getting thinner by the week. Here's a sharp look at what's moving beneath the surface of the cybersecurity world as 2026 begin...
