One of the developers of the Blackshades spying tool admitted his guilty to distributing malware on Wednesday at Manhattan's federal court.
A Swedish citizen, Alex Yucel (24), was accused of participating in his development Blackshades RAT (remote access Trojan) as well as for sale from 2010 to 2013 through an organized network of thousands of people.
The other developer accused of developing the malicious application is Michael Hogue, who has pleaded guilty in January of 2013 and is currently awaiting his sentence, according to information from the US Attorney's Office for the Southern District of New York.
Brendan Johnston (manager of Blackshades), Marlen Rappa and Kyle Fedorek, who were arrested after having bought Blackshades, are also waiting for their sentence.
The RAT was distributed through an "underground" forum, allowing an attacker to access data on the affected computer, collect information that was "leaked" to the keyboard, and activate the camera to spy on the victim.
In its list of features, there was and is the ability to conduct distributed denial-of-service attacks (DDoS).
The two developers had the malicious tool from 40 to 100 dollars, and are believed to have received around 350.000 dollars from sales.
According to the researchers, Blackshades has infected over 500.000 computers in more than 100 countries. 2014, the FBI made a global business to prosecute Blackshades, which ended with the capture of about 100 people.
Yucel was arrested in Moldova by 2013 and is the first to be issued by that country in the United States.
He faces the maximum prison sentence that reaches 10 years and is scheduled to appear in court at 22 May to appeal.
According to 2013's original indictment, Yucel was charged with a total of five categories: a conspiracy to commit online piracy, malware distribution, a conspiracy to commit access to devices, and distinct identity theft.
