UK government computer systems have been targeted by Crackers at least 85 times in the last five years, and over half of the attacks were made on the Ministry of Defence (MoD).

MoD systems were cracked at least 48 times in that period, and 12 times in 2001. The Lord Chancellor's Department has confirmed evidence of 19 cracking incidents in the last five years, three by outsiders and 16 by internal staff.
