The Canadian Revenue Agency (CRA) has now restored its online services, after being offline since Monday due to a series of cyberattacks.
On Monday, online services were disabled after hackers used thousands of stolen accounts to access government services. More than 5,000 accounts had been targeted in 3 separate attacks.
The CRA has updated its security systems to protect accounts from future attacks.
All victims of the attack will receive a letter from the CRA with steps on how to confirm their identity and restore access to their account.
