Tens of thousands of cyber attacks are being sent on the internet every second.
Each one unique.
This map shows the real-time threats being received at cyber security specialists FireEye.
Jason Steer is the director of technology strategy.
SOUNDBITE (English) JASON STEER, DIRECTOR OF TECHNOLOGY STRATEGY, FIREEYE, SAYING:
"I can download the same file two minutes apart, and that file will have changed it's signature again in two minutes. So it's like trying to nail jelly to a wall. and that's why the whole security industry has to change and our customers and everyone who works in security has to change that, security is not about preventing bad things happening anymore, it's about how quickly can I detect a bad thing happening in my business and how quickly can I isolate and contain that threat from damaging my business further."
The biggest cyber threat at the moment is Gameover Zeus - a virus described as the most sophisticated ever.
Already responsible for stealing hundreds of millions of dollars, it's thought to be capable of a whole lot more.
Don Smith from Dell SecureWorks has been tracking it for three years.
SOUNDBITE (English) DON SMITH, TECHNOLOGY DIRECTOR, DELL SECUREWORKS, SAYING:
"Worst-case scenario it's capable of absolutely anything that you can do on your computer. So that as you are making changes to your online banking, it can be altering destination bank accounts in the background and hiding from you the fact that the money is going to a completely different bank account. And then when you're looking at account summaries, if they choose, they can again obfuscate the fact that money has been moved."
Like other banking trojans, Gameover Zeus is spread using phishing emails - offering fake tax refunds or phony deliveries.
The difference is what happens next.
The virus connecting your infected machine to a web of others.
So instead of one source, the virus now has an estimated two million.
SOUNDBITE (English) IVOR BENNETT, REUTERS REPORTER, SAYING:
"The other thing that makes this virus so unique is its two-pronged attack. Because if your bank account's empty, it'll target your files instead. Music, videos, photos, spreadsheets - anything it thinks could be sensitive, it will encrypt and hold it to ransom."
According to the FBI and the UK equivalent, users have around two weeks before Gameover Zeus reinvents itself and strikes again.
Urging users to back-up files and download protective software.
The best piece of advice though? Don't open any mystery emails or attachments.
Because if the offer sounds too good to be true, it generally is.
