(CNN) — A security firm has identified a teenager in Russia as the author of the malware used in the cyberattacks against Target and Neiman Marcus, and warned retailers to be prepared for more potential breaches.
Investigators have been probing the recent holiday season cyberattack where a massive breach at Target compromised credit card numbers and other personal information of 70 million customers.
In a statement published Friday, Security firm IntelCrawler said the breach was the result of malware that infected Target’s system and possibly compromised the systems of other retailers. Neiman Marcus reported a similar security breach this month.
The malware, which IntelCrawler describes as an “off-the-shelf” product known as BlackPOS, was allegedly written by a 17-year-old with roots in St. Petersburg.
