SPRINGFIELD (WGGB) — A security firm believes a teenager in Russia is responsible for the malware used in that massive data breach at Target stores. The breach compromised the credit card numbers and personal information of nearly 110 million customers.
Security firm InterCrawler says the malware was written by a 17-year-old with roots in St. Petersburg, Russia.
Experts say the first sample of the code was finished last march, and since then, they say more than 40 versions of it has been sold worldwide.
Cybersecurity experts warn the malware may have already infected at least six more retailers and more breaches may happen as a result.
