Trends, Tools, or Tactics of Interest

AI-Related Threats:
- Attackers are exploiting vulnerabilities in AI-related platforms (Langflow, LiteLLM, Claude extension).
- Researchers demonstrated that AI assistants (e.g., Copilot) can be manipulated to display phishing messages and leak internal information.
- AI-powered dependency management tools have been found to introduce or overlook security bugs due to model hallucinations or errors in recommending software versions.
Phishing and Social Engineering:
- Scammers are abusing Google Calendar invites to deliver phishing subscription renewal notices, using embedded phone numbers for social engineering.
- Multi-stage fraud attacks are increasingly chaining bots, proxies, and stolen credentials to escalate from signup to account takeover.
Supply Chain Risks:
- Attacks like TeamPCP and GlassWorm highlight ongoing concerns about the integrity of software supply chains and dependencies.
Automotive Cybersecurity:
- Reports indicate a growing threat landscape for connected and autonomous vehicles, with persistent vulnerabilities since the 2015 Jeep hack.
Global Spyware Market:
- Third-party intermediaries are facilitating the expansion of the spyware market worldwide, circumventing government restrictions and transparency efforts.

Regulatory or Policy Developments
