On October 1st CCS temporarily locked 125 people out of their my.ryerson accounts. That meant they could not access their email, RAMSS, D2L, and other Ryerson services until they worked with the CCS help desk to unlock their account.
Earlier that week, CCS became aware that a database containing stolen usernames and passwords was available online. Ryerson email addresses made up 20,261 of the millions of database entries.
Since the database is readily available online, anyone at Ryerson who used the same password at other breached web sites might be at risk.
Ryerson’s IT security team obtained the password database and found 155 accounts where the passwords were identical.
Almost all of the 155 accounts were not protected by two-factor authentication, which would have helped protect them from attackers using the breached database.
Please accept our apologies for any frustration or inconvenience caused by the actions we took to protect these accounts.

On September 26 and 27 CCS temporarily locked 487 people out of their my.ryerson accounts. That meant they could not access their email, RAMSS, D2L, and other Ryerson services until they worked with the CCS help desk to unlock their account.
Earlier that week, CCS became aware that a database containing stolen usernames and passwords was available online. The database was stolen from Chegg, a company that provides textbook rentals and other online services. Ryerson email addresses made up 2,134 of the millions of database entries.
Since the database is readily available online, anyone at Ryerson who used the same password at Chegg and at Ryerson was at risk of having their Ryerson account hijacked. We are also aware from reports at other universities that accounts are being hijacked using the Chegg breach database.
Ryerson’s IT security team obtained the password database and found 487 accounts where the Chegg and Ryerson passwords were identical.
Almost all of the 487 accounts were not protected by two-factor authentication, which would have helped protect them from attackers using the Chegg breach database.
Please accept our apologies for any frustration or inconvenience caused by the actions we took to protect these accounts.
