The Washington Post experienced a cyberattack last week that compromised the email accounts of several journalists, prompting the organization to reset login credentials for all staff members.

Microsoft accounts belonging to teams covering national security, as well as economic and foreign policy, were reportedly targeted, according to the Wall Street Journal.

The outlet is investigating the breach, and there is speculation that the hack may have originated from other nations. The Post previously faced similar cyberattacks in 2011.

News organizations are frequent targets for hackers due to their access to sensitive information and extensive contact networks.
