The zero-click attack is a cyber-threat that does not require any action from the targeted device?s user. This type of cyber attack gained spotlight recently because the Pegasus spyware used this to target over 300 mobile phone numbers in India, including the key ministers in the Union Cabinet.
Since zero-click attack does not rely on human interaction with the target device, the Pegasus gains more control over the device than the owner, even going on to access root-level privileges. This enables it to access sensitive data like contact information, browsing history, internet activities etc.
