The report’s conclusion rejects the common belief that the financial sectors suffer the most from DDoS attacks, as other prominent threat actors are emerging. Reports say that in recent times, brute force attacks, ATO (Account Takeover) attacks, credential stuffing attacks have done more considerable damage on the financial sectors than DDoS, from the year 2017-19.
The ATO attacks include:

- Password Spraying- Hackers use the same passwords but against many individuals.
Similarities between Credential Stuffing and DDoS attacks
According to F5’s reports, the DDoS attacks surged in the year 2019, but these figures cant be entirely accurate. Some credential-stuffing and brute force attacks are so fast and destructive that they are sometimes mistaken for DDoS attacks. The reason for the rapid rise of credential stuffing and brute force attacks is because the availability of leaked usernames and passwords is getting shorter and shorter. Due to scarcity in leaked passwords, the hackers are trying to get as much as they can from the attacks, hence the increase.
Banks in North America a bigger target
According to the experts, North American banks have witnessed the highest number of brute force and credential stuffing attacks because of the availability of leaked passwords and credentials of the North American users on the websites since the last decade. “The combination of a global rise in DoS attacks and an increasing focus in North America on credential-based attacks suggests some ambivalence among attackers regarding the best strategies for extracting value from financial services targets,” concludes F5 in its report.
