Fraudsters capitalize on the uptick in online shopping. Web threats, such as payment card skimming attacks against e-commerce stores, become much more prevalent this time of year.
Zscaler ThreatLabz has observed an uptick in such threats against Magento and Presta-based e-commerce stores. Magento and Presta are e-commerce platforms written in the PHP programming language.
Zscaler shared details of four groups behind skimming attacks with little to no documentation in the public domain so far.
"Most of the indicators related to these attacks have no detection by security vendors," the company said.
These threat actors primarily target retailers in the US, UK, Australia, and Canada. Most of the attacks have a shelf life of more than one month.
