Officers of the cybercrime department of the Brest region, together with investigators, have identified a 17-year-old resident of Hrodna who developed malicious software. The teenager was detained in Hrodna.

The software in question is the Mamont trojan for Android devices. According to the operatives, the teenager wrote it on the order of an acquaintance.

According to law enforcement, the suspect created Mamont at the request of an acquaintance.

The program, according to the operatives, bypassed smartphone protection. Law enforcement said that 120 people were affected by the minor's actions.

Telegram was used for the mass mailing. Users were sent files named "you're in this photo", "car crash video" and other enticing captions that prompted them to open the attachment.

According to the Interior Ministry, once installed, the trojan intercepted SMS messages, collected information about the apps installed on the device and sent it to remote servers.

This information was then used to withdraw money from the smartphone owners' bank accounts.

Law enforcement identified more than 120 victims. The total damage is estimated at about 150000 rubles, just under 51000 dollars.

Investigators opened a criminal case on the development, use, distribution and sale of malicious computer programs.
