Big bangs Headquartered in Helsinki, with offices in Kaliningrad and Tomsk, Russia, Panzerdog is currently working on its debut mobile title, 5v5 physics-based thirdperson/vehicle shooter .

Researchers discovered 57 million account details being traded in Russia.

A large number also belong to Gmail, Hotmail and Yahoo Mail users.

Seven at night on the Friday before Christmas and I was rushing to meet a deadline.

With less than an hour to finish a documentary I was working on, my fingers were flying over my keyboard as I wrestled with the script, phone calls and emails with a researcher abroad while watching multiple TV screens in the cutting room and talking simultaneously to people around me.

'I am in a critical situation in Madrid' the emails said, 'all my money got stolen in the hotel where I lodged due to a robbery incident - I want you to help me with a loan of 1,500 pounds'.

It went on to say that the hotel phone lines had been cut and I did not have my mobile with me - this was to stop people trying to check if the story was true.

The message was unconvincing of course - the grammar was wrong, the English stilted - but as I discovered later many people thought it really did come from me and some emailed back asking where to send the money.

My life was in chaos as calls continued round the clock from Afghanistan and India, from Africa and Washington, from anxious friends and people I knew as a journalist working internationally. I could not raise anyone at Yahoo - there were no phone numbers listed and my electronic pleas for help on their website disappeared into the black hole of cyberspace.

Yahoo Mail credentials totaled 40 million, or 15 per cent of the haul In 2014, Holden, a Ukrainian-American who specialises in Eastern European cyber crime threats, uncovered a cache of 1.2billion unique credentials that marked the world's biggest-everrecovery of stolen accounts.

His firm studies cyber threats playing out in the forums andchatrooms that make up the criminal underground, speaking tohackers in their native languages while developing profiles ofindividual criminals.

Who was doing what inside my email and, more to the point, did Yahoo even care?
