2008, Fannie Mae- A logic bomb
from a contract engineer, who had recently been terminated, attempted to delete data on more than 4,000 servers.
Suppose, for example, that Harry plants his logic bomb

A logic bomb
is an executable file that, once triggered, executes malicious code that deletes files on a server even during power outages or system reboots.
- A piece of unauthorized computer code, usually delivered via e-mail, which attacks a system after verifying certain conditions within that system.
Malicious codes (logic programs that contain executable statements) take various forms, including viruses, Trojan horses, worms and or logic bombs
It will also identify any logic bombs
hidden in the malware waiting for a trigger to cause damage at a later time.
More basic weapons designed to destroy data at a given time, such as kill switches, logic bombs
It seems to me a datacenter, or group of datacenters, would be inviting targets for logic bombs
or for real bombs.
Chris Wysopal, chief technology officer at Veracode, which advises governments on security, said: "If someone is stealing information or planting logic bombs
, it's far more difficult to find them.
