<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 weeks.  The 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).

SciNet/Niagara Downtime Announcement, May 6-7, 2020

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 6th. There 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.
