Retail giant Target this week announced the open source availability of an internal tool designed for the detection of web skimming attacks.
Dubbed Merry Maker, the tool analyzes payment page code served to users and network traffic from test payment transactions to identify any malicious indicators. The company says it has been using the tool since 2018 to perform more than one million website scans.
In addition to simulating a real site visitor and saving the generated code and network activity for analysis, the utility searches for new and known malicious domains and creates an alert when any is identified. The tool supports Basic, Kafka, and GoAlert alerts.
