<b>April 20, 2020: Security Incident at Cedar; implications for Niagara users</b>
 
 
 
Last week, it became evident that the Cedar GP cluster had been
 
comprimised for several weeksThe passwords of at least two
 
Compute Canada users were known to the attackers. One of these was
 
used to escalate privileges on Cedar, as explained on
 
https://status.computecanada.ca/view_incident?incident=423.
 
 
 
These accounts were used to login to Niagara as well, but Niagara
 
did not have the same security loophole as Cedar (which has been
 
fixed), and no further escalation was observed on Niagara.
 
 
 
Reassuring as that may sound, it is not known how the passwords of
 
the two user accounts were obtained. Given this uncertainty, the
 
SciNet team *strongly* recommends that you change your password on
 
https://ccdb.computecanada.ca/security/change_password, and remove
 
any SSH keys and regenerate new ones (see
 
https://docs.scinet.utoronto.ca/index.php/SSH_keys).
 
 
 
<b> SciNet/Niagara Downtime Announcement, May 6-7, 2020</b>
 
  
All resources at SciNet will undergo a two-day maintenance shutdown on May 6th and 7th 2020, starting at 7 am EDT on Wednesday May 6thThere will be no access to any of the SciNet systems (Niagara, Mist, HPSS, Teach cluster, or the file systems) or systems hosted at the SciNet data centre.  We expect to be able to bring the systems back online the evening of May 7th.

Announcement: On June 7th and 8th, 2021, The SciNet datacentre will have a scheduled maintenance shutdown.  Niagara, Mist, HPSS, login nodes, the file systems, and hosted systems will all be offline during the shutdown.
