There’s an app for that: web skimmers found on PaaS Heroku

Criminals love to abuse legitimate services—especially platform-as-a-service (Paas) cloud providers—as they are a popular and reliable hosting commodity used to support both business and consumer ventures. Case in point, in April 2019 we documented a web skimmer served on code repository GitHub.
