Another hacker attack on Munich University - TUM affected

Bayern Hacker attack on Technical University of Munich As of: November 6th, 2026 • 8:23 p.m

Unknown people have hacked university systems at the Technical University of Munich. For example, you could view addresses and passwords. This is the second hacker attack on a large university in Munich.

After an attack on the Ludwig Maximilian University of Munich (LMU) in September, there has now also been a relevant IT security incident at the Technical University of Munich (TUM). The TUM informed about the incident on its website (external link) on Friday afternoon. Accordingly, unknown persons initially attacked the university's "myTUM" portal.

A TUM spokesman told BR on Friday afternoon that the attack was probably intended to gain access to the campus management system "TUMonline" - which was successful. Among other things, passwords of people who had registered with “myTUM” were also accessible. According to the spokesman, they were not the target of the attack. "We are currently assuming that almost no data was leaked, although the possibility existed."

The TUM IT department was able to take the two affected systems offline “very quickly” and thus stop the attack, said the spokesman. During the attack, however, according to TUM, the attackers may have been able to access the following data: passwords, names, private addresses and dates of birth, for employees also work addresses and work telephone numbers, and for students possibly also matriculation numbers, degree programs and number of semesters.

The TUM recommends that everyone affected change their TUM password. According to the TUM spokesman, the “myTUM” and “TUMonline” systems are still offline. The university's IT department wants to bring the "TUMonline" system online again at the beginning of next week. The old system “myTUM” will now remain offline for good.

It was only at the end of September that there was an unprecedented cyber attack on the LMU Munich, which affected around 600,000 data sets from students and former students from the past 50 years. The attackers gained access to the admissions system with enrollment data, sometimes also bank details as well as health insurance and BAföG numbers. Passwords, exam dates and coursework were probably not affected.

This is the European perspective at BR24.
