Commission-free stock trading company Robinhood published a blog post announcing it was the victim of a data security incident where hackers obtained 500 million email addresses, 200 million full names, and more specific personal information including names, birthdates, and zip codes of about 310 people. “Based on our investigation, the attack has been contained and we believe that no Social Security numbers, bank account numbers, or debit card numbers were exposed and that there has been no financial loss to any customers as a result of the incident,” reads the blog post. The company reported that the hack was the result of a bad actor socially engineering a customer report representative. After compromising the data, the hackers then tried to extort Robinhood. 

“No company is immune to hacks. That's something that will happen sooner or later,” commented Luis Corrons, Avast Security Evangelist. “What really makes the difference is the ability to be able to detect it in a short amount of time, and therefore limit the damage caused by the intrusion. Many companies only learn about these incidents months later, which translates into massive data breaches.” Robinhood says it is currently working with authorities to resolve the matter. 

UK Labour party suffers ransomware attack

The U.K. Labour party posted a notification of data incident on its website, telling members that a cyber incident has put the personal information of its members and affiliated supporters at risk. “The full scope and impact of the incident is being urgently investigated,” the notification says. Labour has about 430,000 members. The party says its own servers were unaffected by the attack, which was instead aimed at “a third-party that handles data on our behalf.” Sources close to the incident told Sky News that it was a ransomware attack. The party says the matter is being investigated by the National Crime Agency (NCA), National Cyber Security Centre (NCSC) and the Information Commissioner’s Office (ICO).

In a global crackdown on ransomware groups, two suspects have been charged by the U.S. Department of Justice (DOJ) with committing some of the largest ransomware attacks in recent months.
