For years, security teams had time between discovery and exploitation. Time to triage. Time to validate. Time to prioritize what to fix first. AI has compressed that window. Frontier models now discover and chain vulnerabilities faster than human analysts can confirm them, and the gap between finding and fixing is shrinking in both directions.

In this episode of CyberWire-X, N2K’s ⁠Dave Bittner⁠ and Federico Kirschbaum, Head of XBOW Security Lab, explore what it actually means to run autonomous offensive security, why validation workflows built for quarterly testing cycles struggle to keep up, and how practitioners are redefining what a tested application looks like when the pace of offense has fundamentally changed.

Traditionally, GPS jamming attacks have been confined to the ground; however, new data shows that these attacks could be moving to target signals before they even reach the ground.

In this week’s episode, host Maria Varmazis sits down with Dave Bittner and Brandon Karpf to discuss recent research that suggests the attack landscape for GPS attacks is expanding. If this research is accurate, these attacks represent a significant evolution for how defenders think about this critical technology.

Something is jamming GPS over Europe. Here's what we found.

This week, we are joined by Tom Kellermann, Trend Micro's VP of AI Security and Threat Research, discussing their work on "Inside SHADOW-WATER-063’s Banana RAT: From Build Server to Banking Fraud." Researchers from Trend Micro's MDR team uncovered the full operation behind Banana RAT, a sophisticated banking trojan they track as SHADOW-WATER-063, by analyzing both attacker infrastructure and infected victim systems.

The malware uses fileless PowerShell execution, layered obfuscation, and remote-control capabilities to steal credentials, manipulate banking sessions, intercept Pix QR code payments, and facilitate financial fraud targeting Brazilian banks. The campaign appears to be operated by a Brazilian Portuguese-speaking cybercriminal group with ties to the broader Tetrade banking malware ecosystem and may be evolving toward a malware-as-a-service model.
