This time, it's Twitter CEO Jack Dorsey.
OurMine claimed responsibility for the hack, which was spotted after the group managed to post some benign video clips.
The team also tweeted at 2:50 AM ET today saying "Hey, its OurMine,we are testing your security," with a link to their website that promotes and sells its own "services" for which it has already made $16,500.
Although the tweets posted by the group did not contain any harmful content, both the tweet and linked to a short Vine video clip have immediately been removed.
Ourmine is the same group of hackers from Saudi Arabia that previously compromised some social media accounts of other CEOs including:
- Google's CEO Sundar Pichai
- Facebook's CEO Mark Zuckerberg
- Twitter's ex-CEO Dick Costolo
- Facebook-owned virtual reality company Oculus CEO Brendan Iribe
OurMine claims it is "testing security" of accounts and teaching people to secure their online accounts better, though it also offers its support to those it targets, charging up to $5,000 for a "scan" of their social media accounts, website security holes, and other security vulnerabilities.
Change your passwords for all social media sites as well as other online accounts immediately, especially if you use the same password for multiple websites.
