Three massive cyberattacks dominated headlines this week. Each hit a different pillar of American society.

An Ivy League university lost the data of 870,000 people, Russian hackers (allegedly) infiltrated federal courts, and a principal city went offline for two weeks.

Here's what happened this week in cybersecurity and why it matters to you.

Columbia University suffered a massive cyberattack that exposed the personal information of nearly 870,000 people, including students, employees, and applicants. While unauthorized access began in mid-May, it went undetected for over a month until a technical outage in late June prompted an investigation. The probe revealed that hackers had exfiltrated a vast amount of sensitive data, with multiple outlets reporting that it included 460 gigabytes of information, which comprised Social Security numbers, health records, financial aid details, and academic records.

Key Insights:

What makes this breach particularly alarming is the scope of personal data compromised. Beyond basic contact information, the hackers accessed insurance details, demographic data, and health information that students had shared with the university during their enrollment years. Columbia is now offering two years of free credit monitoring to affected individuals. Still, for hundreds of thousands of people, their most sensitive details may already be in the hands of criminals.

Why This Matters For You:

If you've ever attended college, the university still has troves of data about you. Universities store decades of student data but often lack the robust security infrastructure of financial institutions or healthcare systems. As colleges digitize more records and expand online services, they become increasingly attractive targets for hackers seeking vast troves of personal information in one place.

Hackers with suspected ties to the Russian government have breached the federal court system that handles sensitive legal documents across the United States, including sealed cases and national security files. The hackers exploited their access to monitor criminal cases in New York and other jurisdictions, providing Moscow with unprecedented insight into America's judicial system. The multi-year attack exploited outdated vulnerabilities in the court system's electronic filing system, which includes the public-facing PACER system.

Key Insights:

The breach exposed highly sensitive information that could reveal confidential sources and details about people charged with national security crimes. Think of it like someone rifling through your lawyer's filing cabinet, but this cabinet holds cases involving spies, terrorists, and classified operations. The court system has long been a target for foreign intelligence agencies because it contains a treasure trove of information about ongoing investigations and government secrets.

Why This Matters For You:

This hack echoes the devastating 2021 SolarWinds attack, highlighting how America's critical infrastructure remains vulnerable to sophisticated state actors. President Trump says he "could" bring up the breach during his imminent meeting with Putin today, but the real question is whether our courts can secure themselves before the next attack. Every sealed indictment and witness protection case may now be an open book to Moscow.
