This week saw major AI security risks emerge as researchers found vulnerabilities in DeepSeek's AI systems, allowing hackers to access chat histories and user data. The U.S. government took action with new DOJ data security rules banning companies from sharing sensitive health and location data with China, Russia, and four other countries starting April 8.

Tech giants including Microsoft and IBM launched data safety standards to improve AI systems' trustworthiness through better tracking of information sources. Meanwhile, Virginia's governor vetoed a proposed AI fairness law, calling it "too strict for small businesses".

Lawyers got new guidelines for using AI tools safely, with companies like LexCheck highlighting encryption and data masking features to protect client secrets. China also introduced rules requiring banks to report cyberattacks quickly.

Courts pushed back against some privacy lawsuits, ruling that collecting website clicks and mouse movements doesn't always count as illegal spying. Experts warned that AI security failures could lead to stolen trade secrets or faked legal documents.
