Cyber Threat Intelligence

Threat actors are demonstrating increasing operational sophistication, leveraging blockchain infrastructure to evade detection in RAT campaigns, deploying multi-stage backdoors through supply chain compromises tied to nation-state actors, and exploiting chained vulnerabilities in AI platforms to compromise high-value accounts. Organizations must prioritize proactive CVE validation and robust identity visibility frameworks, as the convergence of AI-assisted attacks and complex digital supply chains continues to expand the attack surface and compress the window between vulnerability disclosure and active exploitation.

Can You Prove a New CVE Is Exploitable Before Attackers Do? Learn How in This Webinar

A new CVE drops. Your scanner finds it. The severity score looks ugly. But that still does not answer the question that matters: Can it actually be exploited in your environment? Mythos-class AI is compressing the time between disclosure and working exploitation, while many security programs still validate risk on weekly or quarterly cycles. The da...

SMB SPOTLIGHT

Small Business Spotlight

Small businesses are increasingly turning to proactive defense strategies to stay ahead of cyber threats — from understanding how adversary simulation works to exploring agentic security approaches. This week's spotlight digs into what SMBs need to know to think like an attacker before one thinks like them.

One does not simply defend agentically

Defenders can’t use AI in the same way attackers can, but there’s much they can do to unlock the potential of agentic cyber defence.

From the CTO's Desk
Daniel Ramos  — CTO — Intelligent Automation  LinkedIn

Happy Monday, cyber-warriors. Grab your coffee, because this week's threat landscape reads like a season finale where every villain gets a spinoff. First up: ClickFix attacks are now deploying something called ChainScript RAT, which uses Polygon blockchain to rotate command-and-control infrastructure. Yes, the bad guys are on-chain now. Nothing says "we've peaked as a civilization" like criminals using Web3 to hide their malware callbacks. Takeaway: block cryptocurrency domain infrastructure at your perimeter and monitor for unusual outbound traffic to blockchain RPC endpoints. Old-school DNS filtering still works wonders.

Meanwhile, Jade Sleet — North Korea's favorite IT freelancers — reportedly breached an Indian IT provider using FLATROOF and ROOFDECK backdoors. The naming convention suggests someone on their red team is really into home improvement. The real fix? Vet your third-party vendors like you're hiring a babysitter, because their access is your attack surface.

Oh, and Claude Opus 5 helped researchers chain vulnerabilities to compromise OpenAI staff accounts. AI hacking AI. We truly live in the future. The lesson isn't "ban AI" — it's "enforce MFA everywhere, always, no exceptions, I don't care how inconvenient Todd finds it."

Finally, identity visibility keeps appearing as the 2026 security theme. If you can't see all your identities — human, machine, and the ones nobody remembers creating — you can't protect them. Audit those service accounts this week. That's not a suggestion; that's homework.
