It spread through exploit kits, phishing, and remote desktop compromise, encrypting files and demanding payment in DASH or Bitcoin. The operators publicly retired in June 2019, but successor families including REvil/Sodinokibi share infrastructure and code with GandCrab. Bitdefender and Europol released free decryptors for several GandCrab versions.
