WARNING: Spear-Phishing Targeting the CS Department

Wednesday, January 29th, 2014

Users may have received a phishing attempt to their CS e-mail account. The subject may be “Account Login Alert!” or “Princeton Security”.

Please be aware that there seems to be a coordinated spear-phishing campaign targeting the CS Department. Various e-mails are being delivered to accounts making assorted claims from improper password use to free money or local news and events.

Remember to always exercise caution with e-mail and web sites. These messages prey on your inattention in order to steal your credentials and use them for various nefarious purposes. DO NOT CLICK SUSPICIOUS LINKS, and DO NOT TYPE YOUR USERNAME OR PASSWORD on any site that you are not 100% sure belongs to the CS Department.

If you are not sure, please feel free to forward suspicious messages to CS Staff (including full headers if you can) and we can verify whether or not the message is valid.

If you may have compromised your account, contact CS Staff

If you need any additional assistance, please contact the CS Staff at any time.

Campus Network and CS Server Downtime, Thu, January 30, 2014, 04:00-08:00

Tuesday, January 28th, 2014

Who is affected:
All users of the CS Department or campus network or computing infrastructure, including, but not limited to, e-mail, web service, and public login hosts.

What is happening:
During this window, OIT will be performing maintenance on the campus network, resulting in no network service outside the CS network. This outage will include internet service and wireless service all over campus.

Also during this time, the CS linux servers will be patched and rebooted. The penguins (tux, opus) and cycles (soak, wash, rinse, and spin) hosts will be reinstalled.

SPECIAL NOTE: As we are reinstalling the penguins and cycles login servers, all crontabs will be deleted. You will need to back up your crontabs before the downtime, and put them back after.

Why is it happening:
This is part of regular maintenance to keep systems up-to-date.
