DoS and DDoS Attacks against Multiple Sectors

The Cybersecurity and Infrastructure Security Agency (CISA) is aware of open-source reporting of targeted denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks against finance and business organizations worldwide.

A DoS attack is accomplished by flooding the targeted host or network with traffic until the target cannot respond or simply crashes, preventing access for legitimate users. In a DDoS attack, the incoming traffic originates from many different sources, making it impossible to stop the attack by blocking a single source. These attacks can cost an organization both time and money while their resources and services are inaccessible.

If you think you or your business is experiencing a DoS or DDoS attack, it is important to contact the appropriate technical professionals for assistance.
