They fooled a lot of people.

Docker containers have been gaining popularity over the past few years as an effective way of packaging software applications. Docker Hub provides a strong community-based model for users and companies to share their software applications. This is also attracting the attention of malicious actors intending to make money by cryptojacking within Docker containers and using Docker Hub to distribute these images.

Palo Alto Networks’ Unit 42 researchers identified a malicious Docker Hub account, azurenql, active since October 2019 that was hosting six malicious images intended to mine the cryptocurrency, Monero. The images hosted on this account have been collectively pulled more than two million times. Additionally, when last checked minexmr.com for this wallet ID, Palo Alto’s team saw recent activity indicating that it’s still being used.

Joining us on this week’s Research Saturday is Jen Miller-Osborn from Palo Alto Networks’ Unit 42 group to share the research and findings.
