The Biden administration took a public stand last year against the abuse of spyware to target human rights activists, dissidents and journalists: It blacklisted the most notorious maker of the hacking tools, the Israeli firm NSO Group. But the global industry for commercial spyware which allows governments to invade mobile phones and vacuum up data " continues to boom. Even the U.S. government is using it. The Drug Enforcement Administration is secretly deploying spyware from a different Israeli firm, according to five people familiar with the agency's operations, in the first confirmed use of commercial spyware by the federal government. The most sophisticated spyware tools " like NSO's Pegasus " have "zero-click" technology, meaning they can stealthily and remotely extract everything from a target's mobile phone, without the user having to click on a malicious link to give Pegasus remote access. They can also turn the mobile phone into a tracking and secret recording device, allowing the phone to spy on its owner. But hacking tools without zero-click capability, which are considerably cheaper, also have a significant market. Commercial spyware has been used by intelligence services and police forces to hack phones used by drug networks and terrorist groups. But it has also been abused by numerous authoritarian regimes and democracies to spy on political opponents and journalists. This has led governments to a sometimes tortured rationale for their use.
