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 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.

Jan 15, 2021: Globus access update on Mon, Jan/18/2021 and Tue, Jan/19/2021:

Please be advised we start preparations on Monday to perform update to Globus access on Tuesday. We'll be adopting oauth instead of myproxy from that point on. During this period expect sporadic disruptions of service. On Monday we'll already block access to nia-dm2, so please refrain from starting new login sessions or ssh tunnels via nia-dm2 from this weekend already.
