Cybercriminals have not finished collecting their holiday gifts. That warning from Kaspersky Lab follows a 23% increase jump over the previous year in malware encounters by users.

Consumers who used their credit cards during the holidays should keep an eye on their transaction information in the coming months, Kaspersky Lab security expert Oleg Kupreev advised. "Typically, criminals don't start to withdraw money from stolen cards right after the theft. They often wait for several weeks or even months to prepare for cashing out."

In its holiday 2016 financial cyberthreats overview Kaspersky Lab suggested it is also too early to draw conclusions on the success of fraud campaigns during the 2016 holiday season, because usually criminals don't cash in stolen payment card credentials immediately. They wait several months in order to make fraudulent transactions less suspicious to the anti-fraud systems of financial organizations.
