According to BBC, there’s no real definition of what a sophisticated attack is, but a more elaborate hacking incident might involve gathering intelligence on a specific, complex network before it could be successfully and subtly exploited.
Attacks
like that do happen. But more often than not, the hackers and
cyber-criminals hitting the headlines aren’t doing anything magical. In
fact, they’re often just wily opportunists – like all criminals.
Because our world is so much more connected than ever before, and those
connections are often woefully insecure, it’s relatively easy to find
ways of exploiting computer systems illegally. And ransomware in general
is increasingly successful. In 2016, criminals made an average of $1,077 with every attack. For the BBC's Cyber-hacks series, Click's Spencer Kelly discovered how cyber-criminals can acquire off-the-shelf ransomware using only a search engine.
“Criminals are lazy as well as clever,” says Woodward. “That’s why they
don’t walk into banks with shotguns anymore. It’s easier to go and steal
stuff online.”
