The Hacker's Choice, also known as THC, is a non-commercial group of international security researchers and hackers.

About[edit]

THC was founded in 1995 in Germany and has published over 70 software releases and technical papers covering a wide range of network and system security aspects.[1][2][3][4]

Notable Projects[edit]

THC Hydra[edit]

THC Hydra[5][6] is a fast and flexible Network Login Hacking Tool.[7] It uses a dictionary attack to try various password/login combinations against an Internet service to determine a valid set of login credentials. It supports a wide set of protocols including Mail (POP3, IMAP, etc.), Databases, LDAP, SMB, VNC, and SSH.

THC GSM Project[edit]

In 2007 the group demonstrated how to receive GSM signals using a software defined radio (USRP).[8][9][10][11][12] In 2008 the group did the first public demonstration how to break A5/1, the GSM encryption algorithm.[13]

THC SSL DOS[edit]

In 2011 the group released a tool (thc-ssl-dos) which exploited a SSL vulnerability.[14] The tool allows an attacker with a regular Internet connection to DoS a more powerful webserver.[15][16][16][17]

Controversial Arrest[edit]

In 2008 a THC member living in the UK was stopped at UK's Heathrow Airport before boarding a plane to speak at the Hack In The Box Security Conference on the topic of GSM Security. The authorities confiscated some of his electronic equipment.[18][19] Thereafter he was allegedly placed on a terrorist watch list. He noticed a triple XXX marking on every boarding pass which required him to comply with additional security checks and frequent stops by Customs when returning to the UK.
