WinRAR Attacks and Zero-Days: Why January’s Security Headlines Should Worry Us All

If you’ve been following security news this past week, you’ve probably noticed a particularly unsettling pattern. We’re seeing active exploitation across multiple critical vulnerabilities, from widely-used compression tools to enterprise SSO systems. What’s especially concerning is how these attacks are targeting both legacy systems we’ve forgotten about and modern infrastructure we depend on daily.

The WinRAR Problem That Won’t Go Away

Let’s start with the elephant in the room. Google’s Threat Analysis Group just confirmed that multiple nation-state actors and cybercriminal groups are actively exploiting CVE-2025-8088, a critical vulnerability in WinRAR that was patched back in July 2025.

AI Security Reality Check: 91% Usage Jump Meets 100% Vulnerability Rate

We’re living through one of those moments where the hype meets harsh reality, and frankly, it’s not pretty. While everyone’s rushing to deploy AI systems across their enterprises, new research from Zscaler just dropped some numbers that should make us all pause: AI security threats are exploding as enterprise usage jumps 91%, and here’s the kicker – they found critical vulnerabilities in 100% of enterprise AI systems they tested.

AI Tools Are the New Attack Vector: From Hijacked LLMs to Emoji-Filled Malware

I’ve been tracking some fascinating developments this week that all point to the same trend: AI and ML tools are becoming prime targets for attackers. What’s particularly interesting is how creative threat actors are getting with these new attack surfaces.

The Bizarre Bazaar: When Your LLM Becomes Someone Else’s Business

The most eye-catching story has to be the Bizarre Bazaar operation, where attackers are systematically hunting for exposed Large Language Model endpoints and then commercializing access to them. Think about that for a second – they’re not just exploiting these services, they’re turning them into their own revenue stream.

The BYOVD Attack That Should Keep You Up at Night (Plus Other Weekly Security Wake-Up Calls)

I’ve been digging into this week’s security incidents, and there’s one that really caught my attention – not just because of what happened, but because of how it happened. The new Osiris ransomware attack on a Southeast Asian food service company is a perfect example of how attackers are getting creative with legitimate tools to slip past our defenses.

North Korean Hackers Cast a Wide Net While Critical Infrastructure Faces New Threats

It’s been quite a week in our corner of the security world. While everyone’s been talking about TikTok’s new joint venture deal, some much more concerning developments have been flying under the radar. Let me walk you through what’s keeping me up at night.

The Contagious Interview Campaign Just Got Scarier

Remember those North Korean social engineering attacks we’ve been tracking? Well, the numbers just came in, and they’re staggering. The PurpleBravo campaign has targeted over 3,136 individual IP addresses across 20 organizations spanning AI, crypto, financial services, and software development.

When Fully Patched Isn’t Enough: The Fortinet SSO Bypass That’s Keeping Us All Awake

I’ll be honest – when I saw the headlines about Fortinet confirming active exploitation on fully patched FortiGate firewalls, my stomach dropped a little. We’ve all been there: you patch everything, check your compliance dashboards, and feel that brief moment of security satisfaction. Then reality comes knocking with news like this.

The Patch That Wasn’t Enough

Here’s what we know so far. Fortinet has confirmed they’re dealing with a FortiCloud SSO authentication bypass vulnerability that’s being actively exploited, even on devices running the latest firmware. The really unsettling part? They’ve identified multiple cases where attacks succeeded on fully upgraded devices, suggesting we’re looking at either a new variant or something that slipped through their initial fix.

When Trust Becomes the Attack Vector: Why Security Culture Matters More Than Ever

I’ve been tracking some concerning trends in this week’s security news, and there’s a pattern emerging that I think we all need to pay attention to. Attackers are getting smarter about exploiting the one thing that’s hardest to patch: human trust.

The New Face of Social Engineering

The most unsettling story I came across involves what researchers are calling “Contagious Interview” attacks. Here’s how it works: attackers pose as potential employers, invite developers to participate in coding challenges, and ask them to clone a seemingly legitimate repository in VS Code. Once the victim grants trust to the repository’s author, malicious code executes with no further user interaction required.

VMware’s Critical Flaw Gets CISA’s Attention While Vulnerability Management Faces Growing Pains

It’s been one of those weeks where the vulnerability management world feels like it’s simultaneously moving too fast and too slow. CISA just added another critical VMware flaw to their Known Exploited Vulnerabilities catalog, while across the pond, Europe’s new vulnerability database is stirring up concerns about making an already complex landscape even messier.

The VMware Problem That Won’t Go Away

Let’s start with the immediate concern: CISA has flagged CVE-2024-37079, a heap overflow vulnerability in VMware vCenter Server with a CVSS score of 9.8. Now, here’s the kicker – this flaw was patched back in June 2024, but CISA is adding it to the KEV catalog now because they’re seeing active exploitation in the wild.

The AI Security Reckoning: When “Move Fast and Break Things” Meets Critical Infrastructure

Remember when our biggest worry was whether someone would click on a phishing email? Those days feel quaint now. This week’s security news reads like a perfect storm of AI adoption outpacing security controls, and frankly, it’s keeping me up at night.

The “Who Approved This Agent?” Problem

Let’s start with what might be the most pervasive issue flying under the radar: AI agent governance. I’ve been in enough incident response calls to know that sinking feeling when you discover a system you didn’t know existed just caused a major problem.

AI Enters the Security Threat Playbook: From Malicious Code Generation to Deepfake Investigations

I’ve been tracking some concerning developments this week that show how AI is becoming a double-edged sword in our field. We’re seeing threat actors weaponize AI tools while platforms struggle with the same technology creating new regulatory headaches.

North Korean Groups Go Full AI for Malware Development

The most striking story comes from researchers tracking the Konni group, a North Korean threat actor that’s now using AI to generate PowerShell backdoors. They’re targeting blockchain developers across Japan, Australia, and India - a significant expansion from their usual focus on South Korea and Eastern Europe.
