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
- Amongst Coalition vessels:
