From paralysing the internet in Estonia to a $4.4-million ransom being paid last week after the shutdown of a major US pipeline, we take a look back at 15 years of cyberattacks.

The Baltic nation of Estonia was the first state hit by a massive cyberattack in 2007, paralysing key corporate and government web services for days.

A 2013 hack that affected all three billion accounts at Yahoo is believed to be the biggest cyberattack in history.

US intelligence agencies accused Moscow of being behind hacking entities Fancy Bear and Cozy Bear which carried out cyberattacks on the Democratic Party.

In the first of a recent trio of cyberattacks against the US, security software company SolarWinds was hacked in late 2020 in an attack lasting months and affecting up to 18,000 clients and more than a hundred US companies.

A cyberattack in mid-May paralysed Colonial Pipeline, one of the largest US oil pipeline operators and the biggest in the east of the country, operating a system that serves 50 million consumers.
