Arrenhe'hwiua telecapture

• Romulan Guard technological development starting mid-22nd century (ENT Novel: Kobayashi Maru, Beneath the Raptor's Wing)
• Infiltration of command-and-control protocols of enemy ships via transmitted computer virus (ENT Novel: Kobayashi Maru, Beneath the Raptor's Wing)
  • Malicious code transmitted as false hail (ENT Novel: Beneath the Raptor's Wing)
  • Upon automated processing of hail via standard handshake and translation procedures, malicious code begins to disseminate itself throughout ship systems (ENT Novel: Beneath the Raptor's Wing)
  • Allows Romulan vessel to take full control of shipboard systems upon reception and integration of foreign agent (ENT Novel: Kobayashi Maru)
• Most effective against vessels with similar technological foundations
  • Amongst Coalition vessels:
    • Greatest effectiveness against Vulcan vessels due to fundamental similarities between Vulcan and Romulan technological schema (ENT Novel: Beneath the Raptor's Wing)
    • Moderately effective against Tellarite and Andorian vessels due to derivation or receipt of Vulcan technology
    • Least effective against Earth vessels given restricted technology distribution from Vulcan (ENT Novel: Beneath the Raptor's Wing)
  • First effective countermeasures distributed June 2156 (ENT Novel: Beneath the Raptor's Wing)
    • Development of protective memory buffers integrated into communications system, holding received messages for analysis prior to handshake (ENT Novel: Beneath the Raptor's Wing)
    • Though successful on Earth vessels, first generation countermeasures also led to memory cascade failures throughout computer systems (ENT Novel: Beneath the Raptor's Wing)
    • Flaw soon pinpointed after initial failure at Altair VI, corrected by offensive at Deneva
  • Tactic and countermeasures continued evolving throughout Earth-Romulan War, but attack vector largely defeated and obsoleted by Battle of Cheron (ENT Novel: To Brave the Storm)
  • Specific attack vector retired following Earth-Romulan War, outside general relevance to standard intervessel cyberwarfare
