Hackers “mislead certain employees” to gain access to internal tools to take over high-profile accounts and push out a Bitcoin scam.
A mobile spearphishing attack targeting “a small number of employees” is what led to the unprecedented, major attack earlier in the month on high-profile Twitter accounts to push out a Bitcoin scam.
The company posted an update late Thursday on the situation, which has been unfolding since July 15, when 130 accounts of high-profile users such as Bill Gates, Elon Musk, Apple and Uber each were hijacked at the same time to promote a bogus advance-fee cryptocurrency deal.
“This attack relied on a significant and concerted attempt to mislead certain employees, and exploit human vulnerabilities, to gain access to our internal systems,” the company said in its update. “This was a striking reminder of how important each person on our team is in protecting our service.”

On the day of the attack, Twitter revealed that the accounts fell victim to a compromise of the company’s internal systems by a group of unidentified hackers that managed to access Twitter company tools and secure employee privileges. Until Thursday, Twitter had not yet confirmed exactly how attackers got access to those internal tools, a point that the company has now clarified.
Twitter acknowledged Thursday that there has been “concern following this incident around our tools and levels of employee access,” and said that it’s taking steps and updating its account tools to make them more “sophisticated” to prevent such a breach in the future.
Those steps include significantly limiting access to internal tools and systems to ensure ongoing account security while the company completes its investigation. This unfortunately will result in some disruption of user account service, including limiting access to the Twitter Data download feature and other processes, Twitter acknowledged.
The company continues to investigate the attack and work with “appropriate authorities” to identify and those responsible. In the meantime, there continues to be widespread speculation and reported evidence about who may be behind the hack, but no solid conclusions.
