Fifteen people have been arrested, including four in the UK, in connection with the hijacking of computers.
Police say the individuals were using software designed to remotely control computers - allowing for the stealing of information.
The other arrests were made in Estonia, France, Romania, Latvia, Italy, and Norway.
The practice, which in some instances can grant access to a victim's webcam, is known as "Ratting".
The phrase takes its name from the malicious software used to gain control - Remote Access Trojans (Rats).
Using Rats to view people through their own webcams, without their knowledge, is becoming "increasingly common" according to the UK government-backed Get Safe Online advice website.
The National Crime Agency (NCA) said it arrested two 33-year-old men, and a 30-year-old woman, in Leeds.
