At around 2:50 a.m., according to a report from Engadget, hackers operating under the name OurMine, took over Dorsey’s Twitter account, posting the message, “Hey, its OurMine, we are testing your security.”
That message linked to the group’s website and a Vine video which displayed the group’s name and an image of a hooded figure.
Unlike some high profile Twitter hacks, this one was relatively short-lived as the tweets were reportedly scrubbed from Dorsey’s Twitter feed less than an hour later.
In the same 24 hour time span, other tech luminaries such as Yahoo CEO Marissa Mayer and venture capitalist Vinod Khosla also reportedly had their Twitter accounts hacked by OurMine.
Ironically, a warning pops up from Twitter if you try to access the Our Mine website advising that it’s probably not safe.The suspicious tweets and videos have since been deleted.Last month, Facebook founder Mark Zuckerberg was hacked on Twitter and Pinterest.
Dorsey hasn’t addressed the brief hacking event on his Twitter feed, but the fact that the co-founder of the service could have his account breached in such a way should serve as a security warning to all users. Not only should you use strong passwords, but you should also regularly change passwords that have been in use for a long time. In the case of Twitter, this could be even more important given reports that roughly 33 million Twitter passwords are being sold on the dark web.
The OurMine group continues to tout its activities as “testing” the security of some of the biggest names in tech, with each hacking event simply demonstrating control of the account rather than posting malicious messages, as is common with many hacking incidents.
Back in June, the OurMine hackers made news when they hacked into the Twitter and Quora accounts of Google CEO Sundar Pichai. And in the first week of June, they were also behind the hacking of Facebook CEO Mark Zuckerberg’s Twitter and Pinterest accounts and Twitter co-founder Ev Williams’ Twitter account.
