With hundreds of millions of views, YouTuber Ghanem al-Masarir was flying high.
From his flat in Wembley, the loud-mouthed and sometimes offensive comedian was making waves as a critic of the Saudi Arabian royal family. But as well as fans, he'd made some powerful enemies.
The first thing al-Masarir noticed was that his phones were behaving weirdly. They had become very slow, with the batteries running out quickly.
Then he noticed seeing the same faces appear in different parts of London. People who seemed to be Saudi regime supporters began stopping him in the street, harassing and filming him. But how did they know where he was all the time?
Al-Masarir feared his phone was being used to spy on him. Cyber experts would later confirm he'd become the latest victim to be spied on with the infamous Pegasus hacking tool.
