Columbia University's network was the target of a cyberattack last week by what officials describe as a politically motivated "hacktivist," causing significant data breaches and network outages across campus. An estimated trove of sensitive data from over 2.5 million students, applicants, and employees at the university was compromised, including social security numbers, citizenship statuses, and other personal information, as reported by ABC7NY.

The cyberattack, which occurred on June 24, led to a complete system shutdown for several hours, during which time students and faculty members found themselves locked out of vital services such as email accounts and course-related software, in addition to encountering unauthorized images of President Donald Trump on public monitors around the campus. While Columbia University officials have remained tight-lipped about the details of the political motivations behind the attack, they acknowledged the ongoing investigation to determine the extent of data theft, as per a statement made to ABC7NY.

Information on the attack indicates that it was orchestrated by an individual who confessed to deliberately targeting the university to uncover and expose documents related to the use of affirmative action in admissions – a policy that has recently been declared unconstitutional by the Supreme Court, according to the New York Post. The unidentified cyber trespasser, who managed to infiltrate the university's servers after a two-month-long effort, claimed responsibility for the attack in an anonymous message sent to Bloomberg News.

The university's swift action restored most systems shortly after the incident, although the fallout from the breach continues, with a focused commitment on securing the network and fully investigating the cyberattack, stating "We know that this news may raise questions and concerns across our community about the scope of the affected personal information. Our team is working toward answer" in an email to students and faculty obtained by the New York Post. Amidst the digital cleanup efforts and reassurance that the Irving Medical Center has not been affected, the university has identified the hacker’s tactics and signature and assured that no further malicious activities have been detected thus far.

Concurrently, the renowned educational institution finds itself under scrutiny by the Trump administration, which has threatened to withdraw roughly $400 million in federal funding over alleged inadequacies in combating antisemitism on campus.
