Intelligence agencies in Germany can now use malware to track computers of people under suspicion. The Trojan will be able to track user chats and conversations on smartphones and PCs.
A spokesman for the German interior ministry announced on Monday that the government had approved the usage of Trojans to monitor suspected citizens.
The interior ministry spokesman defended the government's decision, saying "basically we now have the skills in an area where we did not have this kind of skill." The program was already endorsed by members of the government in autumn 2015, the ministry said.
Trojans are software programs, also known as malware, specially designed to get into users' computers. They are often used by hackers and thieves to gain access to somebody else's data.
In order to use the malware, government officials will have to get a court order, allowing authorities to hack into a citizen's system.
