Comparatively primitive communications gear and other hardware throughout these ships also reduced or eliminated the ability of the Cylons to hack into or shut down a shipboard function. In the case of total power loss, the Colonials also installed [[sound-powered phone]]s on the original battlestars as a last-ditch communications measure. | Comparatively primitive communications gear and other hardware throughout these ships also reduced or eliminated the ability of the Cylons to hack into or shut down a shipboard function.

In the second Cylon War, the [[Cylons (RDM)|Cylons]] use a slightly different means of electronic infiltration, after their espionage determined that Colonial use of computer technology has become widespread once again, 40 years after the first war.

However, instead of using viruses, backdoors are planted in the [[Command Navigation Program]], the operating system used by the Colonial military, by a [[Number Six|human-looking agent]]. | ||
These exploits make it possible to remotely shut down all computers on Colonial warships and fighters, without a possibly lengthy period of time to bypass a computer's defenses ([[Miniseries]]). | |||
Because ''Galactica'' continued its "no networks" historical tradition, the Cylons could not overcome the battlestar by electronic subversion, and are forced to directly attack the ship. While ''Galactica's'' last [[Viper Mark VII]] squadron (which used the [[CNP]]) were compromised and destroyed, ''Galactica'' had, by happenstance, a squadron of [[Viper Mark II]] fighters, which, as similar to or identical to the Cylon War-era Vipers, were impervious to CNP compromise. The Mark IIs gave ''Galactica'' sufficient defenses until it was able to rearm itself at [[Ragnar Anchorage]]. | |||

Some time later after leaving Colonial space, ''Galactica'' suffers a Cylon virus infection near the legendary planet of [[Kobol (RDM)|Kobol]]. The viral attack occurs after [[CIC]] is forced into doing what Commander [[William Adama]] (at the time, seriously wounded in an assassination attempt) would never normally allow: The temporary networking of several of the battlestar's computers. The temporary network is needed to greatly reduce the computation time needed to find the proper coordinates of the missing civilian [[The Fleet (RDM)|Fleet]], which jumped to a different set of coordinates ([[Scattered]]). | |||

The virus replicated into other systems on the system, probing and learning control and weaknesses.

Caprica-Valerii offers her services to eradicate the virus by connecting herself through her [[Cylon data port]] to the Colonial mainframe and communication systems through a fiber optic cable. The battlestar erases its hard drives to eradicate the logic bomb, but is left completely defenseless for a time, save Valerii's efforts. | Caprica-Valerii offers her services to eradicate the virus by connecting herself through her [[Cylon data port]] to the Colonial mainframe and communication systems through a fiber optic cable.
