Against a backdrop of rising geopolitical tension and growing cyber-criminal activity, Tokio Marine HCC International has compiled its list of the top 10 2023 cyber incidents in terms of financial impact and reputational damage.
For the second year in a row, a nation-state attack is prominently featured on the list, with multiple significant cyber-attacks being launched by Hamas and its allies against Israel at the start of the conflict in the middle east.
A large DDoS attack was detected against websites that provided critical information to civilians on rocket attacks, and criminal group AnonGhost also exploited a vulnerability in a mobile app that alerts Israeli civilians, most notably allowing them to intercept requests and send fake alerts.
In line with a growing presence of ransomware attacks, this attack vector featured heavily, making up four of the 10 spots on the list. Data breaches were the second most common type of attack, appearing three times.
The report also features the largest DDoS attack ever recorded – a failed attack on Google which peaked at 398 million requests per second.
