Distributed Denial of Service (DDoS)

The research on cyber threats finds that DDoS attacks are conducted to distract networks, leading to business stoppages and disruptions in work. Such attacks may happen only for a few minutes, not to steal information but to frustrate the victim by creating delays, leading to a loss of service. 

Furthermore, the attack volumes increased in 2021, where some such crimes were politically motivated and targeted a specific victim, while some sophisticated attacks aimed to steal information.

How Does It Work?

There can be two types of DoS attacks: crashing and flooding. Crashing is less common, but it can stop work, and flooding leads to saturation due to a high number of requests from multiple users, leading to overload and suspensions. 

DDoS refers to the multiple systems that conduct synchronized attacks on a target. It can be difficult to prevent as it does not hack or steal information but disrupts network functions to create stoppages that shut down the systems altogether. 

However, such attacks can be powerful, and attackers mostly use bots to infect the devices and access control the processors. 

How Does It Happen?

The criminals may use a piece of software to access a company's website and use techniques like IP spoofing to access various sites, and the users cannot access the site and its services, which leads to a  complete site failure.

How To Identify It?

• If you suddenly lose network connection in your device and server previously working properly.

• If the website performance declines suddenly.

• If the employees could not open files stored on a specific network. 

• Sometimes, the criminals conduct test attacks to identify the vulnerabilities in a website, mainly to prepare for larger attacks later.

• Sometimes, such initiatives are pure distractions planned to attempt fraud. 

If you suspect such fraud, raise concerns and report it to the regulatory agencies. Also, keep a record of the timeline of events to track the activities on a network, like the server activities, logs, data, packet capture, and graphs. 

The technical teams may have to increase the bandwidth, build complex servers and reconfigure the hardware to reduce the risks. Also, install the endpoint protection and the most appropriate firewalls in the servers.
