24-year-old security researcher Zammis Clark
pleaded guilty today to hacking into Microsoft and Nintendo servers and stealing confidential information. Clark, known online as Slipstream or Raylee, "was charged on multiple counts of computer misuse offenses in a London Crown Court on Thursday, and pleaded guilty to hacking into Microsoft and Nintendo networks," reports The Verge. From the report:
Prosecutors revealed that Clark had gained access to a Microsoft server on January 24th, 2017 using an internal username and password, and then uploaded a web shell to remotely access Microsoft's network freely for at least three weeks. Clark then uploaded multiple shells which allowed him to search through Microsoft's network, upload files, and download data. In total, around 43,000 files were stolen after Clark targeted Microsoft's internal Windows flighting servers. These servers contain confidential copies of pre-release versions of Windows, and are used to distribute early beta code to developers working on Windows. Clark targeted unique build numbers to gain information on pre-release versions of Windows in around 7,500 searches for unreleased products, codenames, and build numbers.
Clark then shared access to Microsoft's servers through an Internet Relay Chat (IRC) server chatroom, allowing other individuals to access and steal confidential information. Prosecutors say other hackers from France, Germany, the United Arab Emirates, and other countries were then able to access Microsoft's servers. Police found the stolen files on Clark's home computer after a joint investigation involving Microsoft's cyber team, the FBI, EUROPOL, and the NCA's National Cyber Crime Unit (NCCU). [...] The Microsoft intrusion ended when Clark uploaded malware onto Microsoft's network, and he was subsequently arrested in June, 2017. Clark was then bailed without any restrictions on his computer use, and went on to hack into Nintendo's internal network in March last year. Clark gained access through Virtual Private Networks (VPNs) and used similar software to hack into Nintendo's highly confidential game development servers. These servers store development code for unreleased games, and Clark was able to steal 2,365 usernames and passwords until Nintendo eventually discovered the breach in May 2018. Nintendo estimates the cost of damages between $913,000 and $1.8 million, and Microsoft previously provided the court with a vague estimate of around $2 million in damages. 26-year-old Thomas Hounsell, known in the Windows community for running the now discontinued
BuildFeed website, appeared alongside Clark in court on Thursday for using Clark's Microsoft server breach to conduct more than 1,000 searches for products, codenames, and build numbers over a 17-day period, the report adds.
