The malware responsible for a cyber-security breach affecting Target stores may be more widespread than originally thought.
An international and nearly undetectable malware may have corrupted point of sale systems of multiple retailers.
A bulletin distributed to retailers by the Department of Homeland Security, suggests the shocking holiday breach affecting Target stores across the count has "potentially infected a large number of retail operations".
A cyber attack that has already compromised the credit card data of 40-million Target customers and the information of up to 70-million more.
According to a cybersecurity firm called "iSIGHT" who has contributed to the investigation, "many retail organizations may not know that they have been infected this software contains a new kind of attack method that is able to covertly subvert network controls and common forensic tactics, concealing all data transfers."
iSIGHT called the malicious computer code, kaptoxa; a Russian word because parts of the code were written in russian
According to the Wall Street Journal, who spoke to sources familiar with the report, parts of kaptoxa have been on the internet's black market for weeks.
The paper added that unnamed US officials say: These details "suggest the attack may have ties to organized crime from the former Soviet Union."
And in a newly issued email by Target to its customers, the cyber attack stole much more than pin numbers: Names, mailing address, phone numbers and email addresses were also taken.
