Over the past several weeks, the cybersecurity community has been reminded how quickly frontier and agentic AI in defense networks can challenge our assumptions. When Anthropic's Claude Mythos model was made available to a limited set of organizations as a technical preview, it was reported that an unauthorized group claimed that it had gained access within hours. The incident, if true, was more than a possible breach. It was a warning. The potential impact of advanced AI on U.S. defense and intelligence networks is significant. As the U.S. government moves to deploy AI capabilities on classified networks, the opportunity is clear: advanced AI can help accelerate decision superiority for American forces . But the risks are expanding just as quickly, particularly as agentic AI begins to operate across sensitive networks, data environments, and mission workflows. AI adoption is not simply about deploying powerful models. It requires the right security, governance, and resilient...

Attacks on your network are often meticulously planned operations launched by sophisticated threats. Sometimes your technical fortifications provide a formidable challenge, and the attack requires assistance from the inside to succeed. For example, in 2022, the FBI issued a warning 1 that SIM swap attacks are growing: gain control of the phone and earn a gateway to email, bank accounts, stocks, bitcoins, identity credentials, and passwords. This past spring, current and former T-Mobile and Verizon employees reported receiving unsolicited text messages asking if they would be interested in some side cash 2 in exchange for intentionally enabling the “ SIM jacking.” These headline-grabbing stories about the malicious insider are certainly real, but many external attacks stem from a much less conspicuous source: the accidental insider . These are career employees, contractors, partners, or even temporary seasonal workers who, through negligence or lack of awareness, enable the exploit...

Digital content is a double-edged sword, providing vast benefits while simultaneously posing significant threats to organizations across the globe. The sharing of digital content has increased significantly in recent years, mainly via email, digital documents, and chat. In turn, this has created an expansive attack surface and has made ‘digital content’ the preferred carrier for cybercriminals and nation-state threat actors. Digital content is the easy way in for attackers, whether it be to launch sophisticated attacks, malware distribution and phishing or ransomware attacks.  Governments and highly regulated industries are particularly vulnerable due to the notoriety attackers can receive and the “prize” or impact that can come in compromising their networks. For Governments and defense agencies, this could mean losing access to sensitive and classified information. For critical infrastructure and highly regulated industries that could mean disruption to services or physical dam...
