🏆 We’re honored to be recognized as a winner in the 2026 Fortress Cybersecurity Awards for Threat Detection!

Recognition is a byproduct of the mission. Our focus remains squarely on the adversaries threatening global networks.

For the practitioners on the front lines, this recognition underscores our ongoing operational focus:

- Delivering uncompromised visibility into threat actor origins and infrastructure.

- Equipping incident responders to track and dismantle adversary operations before they weaponize.

- Stripping away the noise to provide pure, actionable intelligence.

We share this milestone not as a conclusion, but as a reaffirmation of our core directive. We are here to empower the global community of defenders to stay ahead of threats, secure critical infrastructure, and ultimately, save and improve lives.

Thank you to our customers, partners, and the global security community who trust Team Cymru to help protect what matters most.

For nearly 29% of exploited vulnerabilities, evidence of exploitation exists before or on the day the CVE is published.

In our latest Future of Threat Intelligence episode, we evaluate the shrinking gap between vulnerability discovery and active exploitation in the wild.

- Data shows that while only 1-2% of all CVEs are actively exploited, the velocity of these specific attacks is consistent and high.

- Waiting for a formal CVE designation before initiating a response means your network is likely already compromised.

- Defenders must shift away from a standard CVSS severity mindset, as it frequently fails to reflect the reality of active, real-world threats.

Stop treating CVSS like a risk metric. 🛑

In our latest episode of Future Threat Intelligence Podcast, host Eli Woodward sits down with Patrick Garrity to drop a hard truth: the severity distribution of exploited vulnerabilities mirrors the overall CVE population.

Translation? The scoring system dictating your patch priority has almost no relationship with what threat actors are actually targeting in the wild. If your SLAs rely solely on CVSS to stop a zero-day attack, you are likely prioritizing the wrong things.

As Patrick points out in the clip below, we have to move away from this highly subjective "severity mindset" if we want to secure our edge devices and get ahead of the next zero-day vulnerability.

Watch the clip for Patrick’s take on the data, and listen to the full episode here to completely rethink your triage logic:

When borderless cybercriminal networks exploit regional blind spots, defense requires global cooperation and internet-scale visibility.

Team Cymru recently acted as a private-sector intelligence partner in INTERPOL’s Operation Ramz—a first-of-its-kind cybercrime operation across 13 countries in the Middle East and North Africa (MENA) region. By delivering external threat intelligence and context-rich telemetry, we helped law enforcement map adversary infrastructure, track illegal cyber activities, and convert raw data into actionable operational leads.

The joint operation targeted malicious infrastructure underpinning phishing, malware, and large-scale cyber scams, delivering significant real-world impact:

-> 201 individuals arrested and 382 additional suspects identified.
-> 53 malicious servers dismantled and seized across participating jurisdictions.
-> 3,867 victims identified and protected from further exploitation.
-> Nearly 8,000 pieces of critical intelligence disseminated to drive regional investigations.

Dismantling the infrastructure that adversaries depend on is central to our mission. By empowering global defenders with the visibility needed to turn technical signals into decisive action, we actively make it harder, riskier, and more expensive for cybercriminals to operate.

Accepting default Windows log sizes actively shortens your forensic timeline during an incident.

In the latest Future of Threat Intelligence podcast, Eli Woodward and Unit 42's Andrew Rathbun detail how a fire-and-forget approach to logging directly benefits adversaries.

Inside the briefing:

- Why stale Sysmon deployments create critical enterprise blind spots.

- Endpoint indicators for DPRK fake IT workers, including USB artifact timestamps.

- Why treating the $J USN Journal as a definitive file system ledger is non-negotiable.

If your threat model assumes adversaries need deep technical expertise to target your infrastructure, you need an update.

An attacker with zero prior IoT experience recently compromised a government network, using commercial LLMs to do the heavy lifting. Claude was used to generate massive, custom Python frameworks for SCADA enumeration and credential harvesting, while ChatGPT acted as the analyst to structure the outputs.

While the OT breach was ultimately unsuccessful, vast amounts of sensitive IT data were stolen. The takeaway is clear: the barrier to entry for complex, multi-stage intrusions has vanished.

On this week's Dragon News Bytes, Eli Woodward and Stephen Campbell break down how AI is accelerating adversary tradecraft at scale, and what it means for the defenders tracking them.

Artificial intelligence is a force multiplier for incident response, but it is not a source of forensic ground truth. Relying on it without strict validation introduces critical errors into investigations.

In our newest threat intelligence briefing, Team Cymru's Eli Woodward and Unit 42's Andrew Rathbun detail how to practically deploy AI during incident response:

- AI rapidly accelerates the analysis of unfamiliar log syntax, such as translating Linux audit log timestamps into readable formats.

- Hallucinations remain a persistent risk, requiring experienced analysts to validate outputs against raw data.

- When coupled with robust native logging, such as properly sized Volume Shadow Copies and the $J USN Journal, responders can efficiently map exact intrusion timelines.

RISEx Chicago is just one month away.

Effective defense requires unvarnished intelligence and a trusted network. This is a TLP:RED environment designed specifically for those actively defending networks and investigating adversary operations.

- Dissect peer-led case studies on adversary infrastructure.

- Exchange unfiltered threat data in a secure, vetted environment.

We've built a global community of defenders because unified intelligence sharing is how we stay ahead of emerging threats and protect critical infrastructure.

Just a few spots remain. Apply for an invitation: https://t.co/onorL4TaSK

DPRK IT workers continue to infiltrate corporate networks using fraudulent identities. Senior Threat Intelligence Analyst Eli Woodward (@ElijahWoodward9) details how these adversaries leverage freelance platforms to bypass traditional hiring controls.

- Network traffic correlates these operations with AI developer tools and platforms like Workana.

- Operators use American and Latvian residential IPs alongside VPNs to mask their true locations.
