Kaspersky Lab's Survey, "2016 IT Security Risks," found that industrial sabotage was considered the most likely cause behind a DDoS attack, as it was higher in ranking than political conspiracy and personal vendetta at the expense of a business. Only one in five attack victims (20%) accused foreign governments and intelligence agencies, with the same percentage (21%) suspecting unhappy former employees.
In assessing the overall picture, more than half (56%) victims of DDoS attacks in Asia and the Pacific blame their competitors, and more than a quarter accused foreign governments (28%). Personal mistakes are high in the rankings also for that particular area.
One in three (33%) blame former staff. However, only a third (37%) of businesses in Western Europe suspect dirty game by its competitors, with a fifth (17%) blaming foreign governments.
Observing behavior according to business size, small businesses are more likely to suspect their competitors when experiencing a DDoS attack.
48% of representatives of small and medium enterprises consider this to be the reality, compared to only 36% of large enterprises. On the contrary, MrfaceMany of the big companies believe that former employees and foreign governments bear the greatest responsibility.
“It's clear that businesses feel that their information systems and personal data they are under siege from all sides" asaid Kirill Ilganaev, Kaspersky Lab's Head of Kaspersky DDoS Protection. "With DDoS attacks being so frequent and powerful, many suspect that competitors are hiding behind them, looking for ways to put their pupils out of action and as a result steal their customers. With these insidious tactics constantly increasing, it is imperative for businesses to be protected and remain impervious to possible attacks, so they can stay in the game. "
