Financial Industry Shaken by DDoS Attacks
Distributed denial-of-service (DDoS) attacks are one of the most common techniques along with cyber criminals. Despite being temporary, DDoS attacks can have a significant impact on organizations.
DDoS attacks became a big issue again last year during the Russia-Ukraine conflict. Due to the attacks, the websites of state-owned banks and the government in Ukraine experienced massive network traffic in February 2021, which was an immense pressure during that time.
SOCRadar analyzed the financial institutions’ threat landscape in its industry report to help cybersecurity professionals to eliminate cyber risks like DDoS attacks. Click the button below to download the full report.
DDoS attacks require more devices than DoS, more specifically a botnet, to flood a server with traffic. Therefore, there are occasionally motives other than simply pressuring a victim. Threat actors may also conduct these attacks to interrupt security procedures, conceal other malicious activity, or disrupt workflow.
Risks of DDoS Attacks
Data theft and hacking of a third party are the primary threats to the financial industry during a DDoS attack.
Vendors from various industries are linked in the financial institutions’ digital environment. Threat actors typically target the most vulnerable vendor, and with a single intrusion, they can gain access to others.
The well-known SolarWinds breach demonstrates that financial institutions must not overlook threats from third parties. DDoS attacks may cover up such attacks, and businesses in a supply chain might become targets of extortion or dark web data leaks.
