CUNY officials are urging students to double check their bank accounts, after a broken laptop containing personal information was taken from the school's financial aid office.
According to CUNY, the computer contained social security numbers, but the files were password protected.
There have been no reports of any breaches, but school officials have contacted the nearly 20,000 students who may be affected just in case.
Officials have not pin-pointed the exact date the computer went missing.
