• A Distributed Denial of Service (DDoS) attack involves multiple compromised devices (botnet) sending a large number of requests to a target server to overwhelm it.
• In a specific type of DDoS attack known as an NTP amplification attack, the attacker exploits the Network Time Protocol (NTP) servers by sending small queries with a spoofed source IP address (the target’s IP).
• The NTP server responds with a much larger reply to the target’s IP address, thereby amplifying the traffic directed at the target.
• This reflection and amplification technique significantly increases the volume of traffic sent to the target, causing denial of service.

Application whitelisting/blacklisting is a technology used to control which applications are allowed to execute on a company’s corporate PCs. Whitelisting allows only approved applications to run, while blacklisting prevents specific applications from running. This approach is effective for managing application usage across an enterprise.

Exploitation - The targeted Environment is taken advantage of triggering the threat actor's code

Installation - Backdoor is placed on the victim system allowing the threat actor to maintain the persistence.

Command and Control - An outbound connection is established to an Internet-based controller server.

Actions and Objectives - The threat actor takes actions to violate data integrity and availability

Personally Identifiable Information (PII) refers to any data that can be used to identify a specific individual. Safeguarding PII is critical to protect individuals’ privacy and prevent identity theft. A driver’s license number (B) is considered PII because it is unique to an individual and can be used to confirm their identity. Other examples of PII include social security numbers, passport numbers, and financial account numbers. It is important to protect such information from unauthorized access to maintain personal privacy and security.
