Last week, cyber security firm IntelCrawler named the 17-year-old Russian "Sergey Taraspov" as creator of the BlackPOS Malware which was used in the Target data breach.
After further investigation, the company update its report saying that 23-year-old Russian hacker named "Rinat Shibaev" is the original author of this malware and Sergey is member of technical support team.
In an interview with Russian news channel LifeNews, Shibaev has admitted that he had developed the BlackPOS(also referred as Kaptoxa) malware.
The hacker says he just took readily available program and developed it with additional features.
He allegedly got help in developing the malware from an unknown person whom he had met online. However, he said that he doesn't even know in which country the person lives.
The hacker also said that he created it for selling it to others, not to use the application by himself.
