Editing Logic bomb

A '''logic bomb''' is a [[Wikipedia:Heuristic_(computer_science)|heuristic]] [[Cylon computer virus|computer virus]] that is used to execute malignant computer functions either upon command or when certain pre-defined conditions are met.  Such bombs are loaded on computers without the users knowledge, or even consent depending on whether or not a flaw of the [[Wikipedia:computer operating system|computer's operating system]] was exploited. 

Given that the [[Cylon]]s were created by the [[Colonial]]s, it is assumed that logic bombs were first discovered and implemented by [[Wikipedia:computer scientist|computer scientist]]s.

== Logic bombs in Galactica's computers ==

When Lt. [[Felix Gaeta]] establishes a [[Computers in the Re-imagined Series|computer]] network aboard ''[[Galactica]]'' in order to facilitate [[FTL]] navigational calculations, pieces of the Cylon virus work through every system's mainframe and rewrite code in ''Galactica'''s operational programs ([[Scattered]]).  A version of this virus demonstrates its abilities after ''Galactica'' rediscovers the civilian [[The Fleet (RDM)|Fleet]], deactivating power throughout the ship ([[Valley of Darkness]]).

Initially, the crew thought it had eliminated the infection, but when, weeks later, computer malfunctions and equipment failures begin to surface, Gaeta is ordered to run diagnostics and review the [[Wikipedia:source code|source code]] of programs aboard the ship.  [[William Adama]] orders that [[Karl Agathon]] be provided a printout of the source code of a suspected program to show [[Sharon Valerii (Caprica copy)|Sharon Valerii]] for her review. Upon reading, Valerii offers her services to eradicate the virus, which is designed to remove human control of the [[Galactica type battlestar|battlestar]]. 

Valerii isolates, ostensibly reprogrammed and resent the virus to the oncoming Cylon forces, disabling them and permitting the [[Viper (RDM)|Viper]] defense to [[Great Cylon Turkey Shoot|destroy the Cylon attack forces with impunity]]. 

All traces of the logic bomb are removed when the [[Wikipedia:hard drive|hard drive]]s of the battlestar are wiped, and the programs loaded from uninfected backups ([[Flight of the Phoenix]]).
