Once the attackers had access to one Onion employee’s account, they used that account to send the same email to more Onion staff at about 2:30 AM on Monday, May 6. Coming from a trusted address, many staff members clicked the link, but most refrained from entering their login credentials. Two staff members did enter their credentials, one of whom had access to all of our social media accounts.
After discovering that at least one account had been compromised, we sent a company-wide email to change email passwords immediately. The attacker used their access to a different, undiscovered compromised account to send a duplicate email which included a link to the phishing page disguised as a password-reset link. This dupe email was not sent to any member of the tech or IT teams, so it went undetected. This third and final phishing attack compromised at least 2 more accounts. One of these accounts was used to continue owning our Twitter account.
At this point the editorial staff began publishing articles inspired by the attack. The second article, Syrian Electronic Army Has A Little Fun Before Inevitable Upcoming Deaths At Hands Of Rebels, angered the attacker who then began posting editorial emails on their Twitter account. Once we discovered this, we decided that we could not know for sure which accounts had been compromised and forced a password reset on every staff member’s Google Apps account.
