We have just learned that a computer hacker has gained access to a number of CCIS administered systems on campus and complied a list of passwords foraccounts on these systems. In order to shut down this activity we have taken York off the Internet so effectively immediately, there is no inbound or outbound network traffic. This includes telnet, rlogin, email, etc. Electronic mail within the York campus network is not affected. We have also shut down the modem pool for approx. an hour so we can be assured that the individual cannot access York using that facility. CCIS personnel are now reviewing the activity logs to determine which accounts and passwords have been recorded by the hacker. If an account has been compromised they will proceed to change the password immediately in order to plug the security leak as quickly as possible. If you are unable to log into your account, please contact Help Services at ext. 55800 for the new password. We apologize for any inconvience this may cause. Please feel free to forward this notice to others. Susan Spence Director, User Services Computing, Communications & Instructional Services
