However, it has continued to take various forms since its discovery and is emerging with all new and integrated process killer that affects several processes of Windows 10 apps, office applications, programming IDEs, languages and text editors.
As per the sources, it was noted in March 2019, that the attackers behind Clop Ransomware started to target entire networks instead of individual systems, they changed the ransom note to imply the same.

Meanwhile, in a conversation with SC Media UK, Javvad Malik, security awareness advocate at KnowBe4, told "Clop is a variant of the CryptoMix ransomware family, but has been evolving rapidly in the last year to disable an increasingly large number of windows processes,"
"The main goal of Clop is to encrypt all files in an enterprise and request a payment to receive a decryptor to decrypt all the affected files," read the McAfee report in August.
