Boston College has sent warning letters to 120,000 of its alumni, after a computer containing their addresses and Social Security numbers was hacked by an unknown intruder.
College officials say they have no reason to believe the intruder was looking for personal information to steal; instead, the attacker planted a program that would enable him to use the computer to launch attacks on other machines. But the school is taking no chances, because of the sensitive information stored on the computer.
