The Katyusha Scanner is a relative newcomer available to black hats that surfaced in early April. It’s a blend of the Arachni Scanner open source penetration testing tool and Telegram. The tool is simple to use, requiring only that an attacker set up a standard webserver with the version of the scanner that has been modified so it can be controlled through a linked Telegram account. The scanner is still available, and the latest update on June 26 introduced Katyusha 0.8 Pro, which was selling for $500 or $250 per license.
