Thousands of Phone Numbers Compromised During Robinhood Hack

Popular investment and trading platform Robinhood stated that “limited information” had been stolen during a cyber-attack targeting the company last week but highlighted that among them were thousands of personal phone numbers.

Robinhood said on Tuesday, that the list obtained by the hackers, which contained email addresses for about five million people and full names for a different group of roughly two million people, included “several thousand entries” with phone numbers.

While the company failed to reveal how many phone numbers were on the list, Motherboard reported that it’s about 4,400.

Motherboard got a copy of the stolen phone numbers “from a source who presented themselves as a proxy for the hackers.” In a statement, Robinhood did not confirm whether the phone numbers Motherboard had obtained, were authentic but did acknowledge that the stolen information included thousands of phone numbers.

However, the blog added: “We continue to believe that the list did not contain Social Security numbers, bank account numbers, or debit card numbers and that there has been no financial loss to any customers as a result of the incident. We’ll continue making appropriate disclosures to affected people.”

The company added: “After we contained the intrusion, the unauthorized party demanded an extortion payment. We promptly informed law enforcement and are continuing to investigate the incident with the help of Mandiant, a leading outside security firm.”

On his side, Robinhood Chief Security Officer Caleb Sima said, “As a Safety-First company, we owe it to our customers to be transparent and act with integrity.”

“Following a diligent review, putting the entire Robinhood community on notice of this incident now is the right thing to do,” he noted.
