Top Cyber Incidents & Threat Alerts

1. FBI: Chinese Espionage Hacking Hits 80+ Countries

A joint FBI-led advisory reveals that a Chinese government-backed hacking group, often referred to as "Salt Typhoon," has dramatically expanded its reach. Once limited to nine U.S. telecoms, it now impacts over 200 American entities and infiltrates critical infrastructure in more than 80 countries, targeting sectors like utilities, transport, and lodging. Persistent access and covert reentry points remain a serious concern. The Washington Post

2. DOJ Takedown of RapperBot—A Record-Breaking DDoS Network

In a major enforcement effort, the U.S. Department of Justice, along with AWS, Google, Cloudflare, and other industry partners, dismantled RapperBot, one of history’s most destructive DDoS botnets. The botnet flexed its muscle by launching over 370,000 attacks across more than 80 countries. A 22-year-old from Oregon now faces up to 10 years in prison. PC Gamer

3. "Vibe-Hacking": AI-Powered Psychological Extortion

Anthropic’s threat intelligence report uncovers “vibe-hacking”—AI models like Claude used to craft highly persuasive, psychologically tuned extortion messages. This method has already targeted at least 17 organizations across various sectors, demanding ransoms exceeding $500,000. The Verge

4. Google's Alert to 2.5 Billion Users Over Intrusions

Google warned its massive user base to reset passwords, enable MFA, and stay alert to phishing—after hackers gained access to a Salesforce database containing business contact info. The intrusion, potentially linked to the "ShinyHunters" group, raises alarms about increasing social engineering threats targeting internal systems. New York Post

5. Deepfakes Threaten Executives—Risk Climbing

New data from TechRadarPro cites the Ponemon Institute, showing a worrying uptick in deepfake impersonations targeting executives (51%, up from 43% in 2023). With AI tools more accessible, even personal devices are becoming a security vulnerability. The recommendation: robust protection that spans both professional and personal digital environments.

6. AI-Generated Ransomware: A New Era Begins

Generative AI is ushering in a dangerous new wave of ransomware. Cybercriminals are now using models like Claude Code to automate everything—from phishing to payload creation—lowering the barrier to entry for complex attacks. ESET and Anthropic have also detected early prototypes like PromptLock—an AI-powered ransomware using local LLMs. WIRED
