While the largest data breach continues to cause headlines and embarrassment in equal measure, it does highlight the fact that cyber data breaches often occur over a period of months and years, rather than being the smash a grab many imagine.

The 11.5 million documents - the biggest leak in history- being picked over by the world's media took a year to exfiltrate from the Panamean law firm in 'dribs and drabs'.

This follows in a similar vein to other notable hacks like Sony, where estimates suggest the hacker was in their network for over a year stealing 100 terabytes of data.
