The cyber threat facing businesses, governments and even end users has been growing at an alarming rate for many years, but 2014 has been a particularly harrowing year for security professionals.
We've seen everything from 'mega data breaches' that exposed thousands, if not millions, of people's personal and financial information, to advanced threats targeting companies that form the backbone of our critical infrastructure.
The influx of new malware and attack campaigns has left many people baffled about the threats they should be most concerned about and what they should look out for in the new year.
So we've created a definitive list detailing the 10 biggest cyber threats to appear in 2014.
10. Energetic bears return
The Energetic Bear hack campaign was originally uncovered by researchers at US security firm CrowdStrike in January.
The operation was focused on stealing valuable data from the energy sector, and targeted companies in the US, Japan, Poland, Greece, Romania, Spain, France, Turkey, China and Germany with watering hole attacks.
The Energetic Bear hackers caused double trouble when they re-emerged in July, mounting even more dangerous attacks that could theoretically cause physical damage to industrial control systems and power plants, like the 2011 Stuxnet virus that targeted Iranian nuclear systems.
The threat posed by Energetic Bear was so severe that the US Computer Emergency Response Team warned companies involved in critical infrastructure to check their systems for signs of infection.
