BOSTON - Cyber security firm IntelCrawler
said on Friday it has uncovered at least six ongoing attacks at
merchants across the U.S. whose credit-card processing systems
are infected with the same type of malicious software used to steal data
from some 40 million credit cards at Target (TGT).
Komarov said that retailers in California and New York were among those compromised with BlackPOS, the same malicious software used in the attack on Target. Their names could not immediately be confirmed.
A Visa spokeswoman said she could not immediately comment.
