Cyberattacks on the CRA
On August 15, 2020 the Canada Revenue Agency has temporarily shut down its online services after the agency confirmed it was recently hit by three cyberattacks that compromised thousands of accounts linked to its services. The federal government described the three separate hacks as a “credential stuffing” scheme — a type of cyberattack that uses passwords and usernames from other websites to access accounts with the CRA. The Canada Revenue Agency expects online services to be fully restored by Wednesday after hackers used thousands of stolen usernames and passwords to fraudulently obtain government services.
