Cybercrime is accelerating at an alarming rate, with Cybersecurity Ventures expecting around $10.5 trillion USD to be lost to the global economy in 2025 thanks to hackers, data thieves, phishers and other “bad actors”.
The biggest, headline-grabbing heists involve eye-watering figures that are hard to comprehend—records and dollars are looted in their millions. But they still offer important lessons in cybersecurity and the cultural issues it encompasses, that individuals or organizations of any size can learn from.
Bernard Marr, a Forbes Contributor and social media influencer at the intersection of business and technology, shares important lessons to be taken from some the most devastating Cyber incidents.
In a recent Forbes article, Marr recalls the 2017 Equifax data breach, the 2017 WannaCry ransomware epidemic, the 2016 Bitfinex crypto exchange hack, the 2023 $25 million deepfake CFO scam, and the 2017 NotPetya Malware attack.
Individuals and institutions alike should learn from these “worst-case scenarios” in order to build resilience against the ever-shifting nature of the cyberthreat landscape. Lessons learned from the incidents covered by Marr can form the skeleton of a defense.
