Hackers have expanded attacks on essential infrastructure like power grids, water systems, and more

Cybersecurity has emerged as one of the defining challenges of 2026, with cyberattacks increasingly disrupting governments, businesses, and critical infrastructure worldwide. 

Digital threats have hit power grids, water systems, healthcare companies, schools, and public agencies.

One of the biggest concerns involves allegations that sensitive Social Security data was improperly handled during activities linked to the Department of Government Efficiency (DOGE). Lawmakers have warned that the incident could become one of the largest data breaches in US history if millions of records were exposed.

Meanwhile, hackers have expanded attacks on essential infrastructure. Cyber intrusions linked to Russia targeted energy grids and water facilities across Europe, while US officials have warned that Iranian hackers are increasingly focusing on American utilities. 

Iranian state-backed hackers also disrupted medical technology company Stryker by remotely wiping thousands of employee devices.

Cybercrime groups such as ShinyHunters continued large-scale ransomware and phishing campaigns, stealing data from millions of users and disrupting schools during exam periods. 

Other high-profile incidents included a breach of an FBI surveillance system, prolonged disruptions at Hasbro, and the exposure of more than 2 million passport and driver’s license records, highlighting the growing risks posed by weak cybersecurity practices.
