Summary of Key Risks and Recommendations

Heightened threat from state-backed APTs (Russia, China) targeting critical infrastructure, enterprises, and dissident communities.
Ongoing exploitation of zero-day and legacy vulnerabilities, especially in enterprise and security products.
Increased risk from generative AI systems, both as attack vectors (prompt injection, jailbreaks) and as privacy concerns for end-users.
Regulatory shifts may impact encrypted communications and patch management practices.
Continued vigilance is recommended for SSH exposure, Git/secrets management, and rapid patching of high-profile vulnerabilities.
