In Wireshark, the filtericmp.type==8is used to detect ping sweep attempts. ICMP type 8 messages are echo requests, which are used in ping operations to check the availability of a network device. A ping sweep involves sending ICMP echo requests to multiple addresses to discover active devices on a network. By filtering for ICMP type 8 messages in Wireshark, Bran can identify these echo requests, helping to pinpoint ping sweep activities on the network.

WMIC (Windows Management Instrumentation Command-line) is a command-line tool that provides a unified interface for Windows management tasks, including the collection of system information. It allows administrators and forensic investigators to query the live system for information about running services, their process IDs, start modes, states, and statuses, among other data. The use of WMIC is particularly valuable in incident response scenarios for gathering volatile information from a system without having to install additional software, which might alter the state of the system being investigated. By executing specific WMIC commands, Clark can extract detailed information about the services running on a system at the time of the investigation, making it an essential tool for collecting volatile data in a forensically sound manner.

When a corporate network ' s servers are sending huge amounts of traffic to a specific website, as detected by the network ' s Intrusion Prevention System (IPS), this behavior is indicative of a Botnet attack. A Botnet is a network of compromised computers, often referred to as " bots, " that are controlled remotely by an attacker, typically without the knowledge of the owners of the computers. The attacker can command these bots to execute distributed denial-of-service (DDoS) attacks, send spam, or conduct other malicious activities. In this scenario, the servers behaving as bots and targeting a website with large volumes of traffic suggests that they have been co-opted into a Botnet to potentially perform a DDoS attack on the website abc.xyz.
