Cybersecurity researchers have uncovered critical remote code execution vulnerabilities impacting major artificial intelligence (AI) inference engines, including those from Meta, Nvidia, Microsoft, and open-source PyTorch projects such as vLLM and SGLang. "These vulnerabilities all traced back to the same root cause: the overlooked unsafe use of ZeroMQ (ZMQ) and Python's pickle deserialization," Oligo Security researcher Avi Lumelsky said in a report published Thursday. At its core, the issue stems from what has been described as a pattern called ShadowMQ , in which the insecure deserialization logic has propagated to several projects as a result of code reuse. The root cause is a vulnerability in Meta's Llama large language model (LLM) framework ( CVE-2024-50050 , CVSS score: 6.3/9.3) that was patched by the company last October. Specifically, it involved the use of ZeroMQ's recv_pyobj() method to deserialize incoming data using Python's pickle module. ...

Criminals don't need to be clever all the time; they just follow the easiest path in: trick users, exploit stale components, or abuse trusted systems like OAuth and package registries. If your stack or habits make any of those easy, you're already a target. This week's ThreatsDay highlights show exactly how those weak points are being exploited — from overlooked misconfigurations to sophisticated new attack chains that turn ordinary tools into powerful entry points. Lumma Stealer Stumbles After Doxxing Drama Decline in Lumma Stealer Activity After Doxxing Campaign The activity of the Lumma Stealer (aka Water Kurita) information stealer has witnessed a "sudden drop" since last months after the identities of five alleged core group members were exposed as part of what's said to be an aggressive underground exposure campaign dubbed Lumma Rats since late August 2025. The targeted individuals are affiliated with the malware's development and administ...

Cybersecurity today is less about single attacks and more about chains of small weaknesses that connect into big risks. One overlooked update, one misused account, or one hidden tool in the wrong hands can be enough to open the door. The news this week shows how attackers are mixing methods—combining stolen access, unpatched software, and clever tricks to move from small entry points to large consequences.  For defenders, the lesson is clear: the real danger often comes not from one major flaw, but from how different small flaws interact together. ⚡ Threat of the Week WhatsApp Patches Actively Exploited Flaw — WhatsApp addressed a security vulnerability in its messaging apps for Apple iOS and macOS that it said may have been exploited in the wild in conjunction with a recently disclosed Apple flaw in targeted zero-day attacks. The vulnerability, CVE-2025-55177 relates to a case of insufficient authorization of linked device synchronization messages. The Meta-owned company ...

Cybercrime has stopped being a problem of just the internet — it's becoming a problem of the real world. Online scams now fund organized crime, hackers rent violence like a service, and even trusted apps or social platforms are turning into attack vectors. The result is a global system where every digital weakness can be turned into physical harm, economic loss, or political leverage. Understanding these links is no longer optional — it's survival. For a full look at the most important security news stories of the week, keep reading. Hidden flaws resurface in Windows core Security Flaws in Windows GDI Details have emerged about three now-patched security vulnerabilities in Windows Graphics Device Interface (GDI) that could enable remote code execution and information disclosure. These issues – CVE-2025-30388 , CVE-2025-53766 , and CVE-2025-47984 – involve out-of-bounds memory access triggered through malformed e...

Everything feels secure—until one small thing slips through. Even strong systems can break if a simple check is missed or a trusted tool is misused. Most threats don't start with alarms—they sneak in through the little things we overlook. A tiny bug, a reused password, a quiet connection—that's all it takes. Staying safe isn't just about reacting fast. It's about catching these early signs before they blow up into real problems. That's why this week's updates matter. From stealthy tactics to unexpected entry points, the stories ahead reveal how quickly risk can spread—and what smart teams are doing to stay ahead. Dive in. ⚡ Threat of the Week U.S. Disrupts N. Korea IT Worker Scheme — Prosecutors said they uncovered the North Korean IT staff working at over 100 U.S. companies using fictitious or stolen identities and not only drawing salaries, but also stealing secret data and plundering virtual currency more than $900,000 in one incident targeting an unnamed blockchain company in ...

Last week's cyber news in 2025 was not about one big incident. It was about many small cracks opening at the same time. Tools people trust every day behave in unexpected ways. Old flaws resurfaced. New ones were used almost immediately. A common theme ran through it all in 2025. Attackers moved faster than fixes. Access meant for work, updates, or support kept getting abused. And damage did not stop when an incident was "over" — it continued to surface months or even years later. This weekly recap brings those stories together in one place. No overload, no noise. Read on to see what shaped the threat landscape in the final stretch of 2025 and what deserves your attention now. ⚡ Threat of the Week MongoDB Vulnerability Comes Under Attack — A newly disclosed security vulnerability in MongoDB has come under active exploitation in the wild, with over 87,000 potentially susceptible instances identified across the world. The vulnerability in question is CVE-2025-14847 (CVSS score: 8.7)...

What if attackers aren't breaking in—they're already inside, watching, and adapting? This week showed a sharp rise in stealth tactics built for long-term access and silent control. AI is being used to shape opinions. Malware is hiding inside software we trust. And old threats are returning under new names. The real danger isn't just the breach—it's not knowing who's still lurking in your systems. If your defenses can't adapt quickly, you're already at risk. Here are the key cyber events you need to pay attention to this week. ⚡ Threat of the Week Lemon Sandstorm Targets Middle East Critical Infra — The Iranian state-sponsored threat group tracked as Lemon Sandstorm targeted an unnamed critical national infrastructure (CNI) in the Middle East and maintained long-term access that lasted for nearly two years using custom backdoors like HanifNet, HXLibrary, and NeoExpressRAT. The activity, which lasted from at least May 2023 to February 2025, entailed "extensive es...

Cyber threats last week showed how attackers no longer need big hacks to cause big damage. They're going after the everyday tools we trust most — firewalls, browser add-ons, and even smart TVs — turning small cracks into serious breaches. The real danger now isn't just one major attack, but hundreds of quiet ones using the software and devices already inside our networks. Each trusted system can become an entry point if it's left unpatched or overlooked. Here's a clear look at the week's biggest risks, from exploited network flaws to new global campaigns and fast-moving vulnerabilities. ⚡ Threat of the Week Flaws in Multiple Network Security Products Come Under Attack — Over the past week, Fortinet , SonicWall , Cisco , and WatchGuard said vulnerabilities in their products have been exploited by threat actors in real-world attacks. Cisco said attacks exploiting CVE-2025-20393, a critical flaw in AsyncOS, have been abused by a China-nexus advanced persistent threat (APT) actor cod...

The internet never stays quiet. Every week, new hacks, scams, and security problems show up somewhere. This week's stories show how fast attackers change their tricks, how small mistakes turn into big risks, and how the same old tools keep finding new ways to break in. Read on to catch up before the next wave hits. Honeypot Traps Hackers Hackers Fall for Resecurity's Honeypot Cybersecurity company Resecurity revealed that it deliberately lured threat actors who claimed to be associated with Scattered LAPSUS$ Hunters ( SLH ) into a trap, after the group claimed on Telegram that it had hacked the company and stolen internal and client data. The company said it set up a honeytrap account populated with fake data designed to resemble real-world business data and planted a fake account on an underground marketplace for compromised credentials after it uncovered a threat actor attempting to conduct malicious activity targeting its resou...
