When Security Infrastructure Becomes the Target: Cisco Firewalls and the Week’s Wake-Up Calls

The Interlock ransomware gang just reminded us why we can’t get comfortable with our security tools. They’ve been actively targeting Cisco enterprise firewalls, and here’s the kicker – they had access to a critical vulnerability weeks before Cisco even disclosed it publicly. Dark Reading reports this group, already known for their double-extortion tactics, essentially had a head start on exploiting what should be our first line of defense.

When 20 Hours Is Too Long: The Reality Check Security Teams Needed This Week

I’ve been watching the security news this week with a mix of fascination and concern. We’re seeing everything from ransomware groups making basic operational security mistakes to threat actors weaponizing vulnerabilities faster than most of us can even read the CVE details. Let me walk you through what caught my attention and why it matters for those of us trying to keep systems secure.

Russian Intelligence Targets Signal Users While Supply Chain Attacks Hit Popular Security Tools

We’re seeing some concerning patterns emerge this week that deserve our attention. While we often focus on protecting our organizations from external threats, recent events show how attackers are increasingly targeting the very tools and platforms we rely on for security.

Russian Intelligence Goes After Encrypted Messaging

The FBI just issued a warning that’s particularly relevant for those of us who regularly use Signal and WhatsApp for sensitive communications. Russian intelligence services are running sophisticated phishing campaigns specifically targeting users of encrypted messaging apps, and they’ve already compromised thousands of accounts.

The Week AI Agents Met Banking Trojans: Privacy Tools Rise While Threats Multiply

We’re seeing some fascinating contradictions in security this week. While privacy-focused companies are raising massive funding rounds and building AI agents to protect us, threat actors are getting more creative with everything from state-sponsored Zimbra exploits to Android malware that reads your note-taking apps. Let me walk you through what caught my attention.

The Privacy Investment Boom Gets Real

Cloaked just pulled in $375 million to expand their privacy platform, and honestly, the timing couldn’t be better. What’s interesting here isn’t just the funding amount – it’s their approach. They’re building AI agents that will actively monitor and enforce privacy preferences on behalf of users.

FBI Takes Down Handala Sites While ScreenConnect Patches Critical Machine Key Flaw

The past week brought some significant developments that deserve our attention, especially if you’re managing remote access tools or keeping an eye on hacktivist activities. Let me walk you through what happened and why it matters for our day-to-day security operations.

The Handala Takedown: 80,000 Devices Wiped at Stryker

The big story this week is the FBI seizing two websites operated by the Handala hacktivist group after they launched a destructive cyberattack against medical technology giant Stryker. We’re talking about approximately 80,000 devices that got wiped – that’s not just data theft, that’s operational destruction on a massive scale.

EDR Killers Are Getting Smarter: 54 Tools Now Using Signed Drivers to Bypass Security

I’ve been tracking some concerning developments in the security space this week, and there’s one story that really caught my attention. We’re seeing a significant evolution in how attackers are dismantling our defenses, particularly when it comes to endpoint detection and response systems.

The BYOVD Problem Just Got Worse

A new analysis shows that 54 different EDR killer tools are now using the “bring your own vulnerable driver” (BYOVD) technique, exploiting a total of 34 signed but vulnerable drivers to disable security software. If you’re not familiar with BYOVD, it’s essentially attackers bringing legitimate, digitally signed drivers that happen to have security flaws, then exploiting those flaws to gain kernel-level access.

PolyShell Hits Magento Hard While Ransomware Groups Air Their Dirty Laundry

We’re seeing some interesting patterns this week that really highlight how the threat landscape keeps us on our toes. The biggest story is definitely the PolyShell vulnerability hitting Magento stores, but there’s also some fascinating drama unfolding in ransomware circles that gives us rare insight into how these operations actually work.

Every Magento Store is Now a Target

The PolyShell vulnerability affecting all Magento Open Source and Adobe Commerce version 2 installations is the kind of bug that makes every e-commerce security team’s stomach drop. We’re talking unauthenticated remote code execution – attackers don’t need credentials, they don’t need to social engineer anyone, they just need to find your Magento store and exploit it.

Major IoT Botnet Takedown Exposes the Scale of Our DDoS Problem

We just witnessed one of the largest coordinated botnet takedowns in recent memory, and honestly, the numbers should make every security professional take notice. The U.S. Justice Department, working with Canadian and German authorities, just dismantled four massive botnets that had compromised over three million IoT devices worldwide.

These weren’t your garden-variety botnets either. The four networks – dubbed Aisuru, Kimwolf, JackSkid, and Mossad – were behind some of the record-breaking DDoS attacks we’ve been tracking lately. When the feds say these botnets could knock “nearly any target offline,” that’s not hyperbole. We’re talking about the kind of firepower that can overwhelm even well-protected infrastructure.

The Marquis Attack Shows Why Third-Party Risk Just Got Real

You know that conversation we’ve been having for years about third-party risk? Well, it just got a lot less theoretical. The Marquis ransomware attack that hit back in August 2025 is finally getting the attention it deserves – and the numbers are staggering.

We’re talking about 672,000 people’s data stolen and operations disrupted at 74 banks across the United States. Let that sink in for a moment. One financial services provider gets compromised, and suddenly three-quarters of a hundred banks are dealing with operational issues. This isn’t just a breach; it’s a perfect case study in how interconnected our financial infrastructure really is.

When Zero-Days Come Knocking: Cisco’s Bad Week and the iOS Surveillance Arms Race

Last week felt like one of those reminders that attackers never take a break. While we were all trying to get through another Tuesday, the Interlock ransomware gang was busy exploiting a maximum severity RCE vulnerability in Cisco’s Secure Firewall Management Center software – and they’ve been at it since late January.

What makes this particularly frustrating is that this was a zero-day attack. The Interlock ransomware gang had months to work with this vulnerability before Cisco even knew it existed. For those of us managing Cisco environments, this hits close to home. FMC is supposed to be the central management platform for our firewall infrastructure – the thing that’s supposed to help us maintain security posture, not become the entry point for ransomware operations.
