This Week’s Top Story

BlackCat hackers threaten to leak Reddit’s data

Back in February of this year, the BlackCat (also known as ALPHV) ransomware gang attacked Reddit by phishing one of their employees, which hackers claim allowed them to steal 80GB of data from the platform. Reddit disclosed that they were hacked on February 5th, and shared that the attackers breached the platform’s systems, giving the threat actors access to “internal docs, code, as well as some internal dashboards and business systems,” said Reddit CTO Christoper Slowe. He also made it known in the post that there were “no indications of breach of our primary production systems,” and that user information, such as passwords, accounts, and financial information were not impacted. 

BlackCat is now claiming that they were behind the February attack on Reddit, and posted a “Reddit Files” page on their leak site. The attackers share that they stole 80GB worth of compressed data, and now plan on leaking all of it if Reddit doesn’t follow through on the gang’s demands. BlackCat attackers said they have contacted Reddit twice since February about their demands, which include a $4.5 million ransom for the data and API policy changes. BlackCat claims that they have received no response from the platform to date, and will release the data if the demands aren’t met. 

Reddit declined BleepingComputer’s request for comment, but the news source is now able to confirm that the attack BlackCat is referencing on their leak site is the same as the February phishing attack on Reddit.
