Air commodore Graham Wright, deputy director of the Office of Cyber Security (OCS), said his Cabinet Office department is developing a "national lexicon" of cyber English.
"We talk about the numbers of attacks we suffer," said Wright in an interview with Computer Weekly. "Attack is where you degrade, deny, disrupt or destroy something. But there are times when we need to be very explicit. Was this really an attack or was it theft?
"Most of what people refer to as 'attacks' are the exfiltration of data, which is theft or espionage," he said. "I haven't seen any reports of attack. Everyone always reports an attack. In most cases it is not an attack, its theft and crime, its stealing data."

Verizon said in its 2009 Data Breach Investigations report that 91% of known cyber breaches were linked to organised crime. What of the remaining 9% was espionage and what could classified by the military as an attack was not stated.
