In Wireshark, to identify ICMP ping sweep attempts, the filtericmp.type == 8 or icmp.type ==0is used. This filter captures ICMP echo requests and echo replies, which are indicative of ping commands. Type 8 represents an echo request used when a source sends a ping, and type 0 represents an echo reply, which is the response from the target. By filtering for these ICMP types, Miko can detect a surge in ping requests across the network, which could indicate a ping sweep attempt—an exploratory activity often used by attackers to discover active hosts on a network by sending ping requests to multiple addresses.

The EC-Council Incident Handler (ECIH) curriculum identifies email spoofing as a common technique in business email compromise (BEC) attacks. Attackers exploit weak or misconfigured DNS-based email authentication controls to forge sender identities.

Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC) are DNS-based mechanisms that validate legitimate email senders and prevent spoofing. Proper configuration ensures that receiving mail servers can verify message authenticity and reject forged communications.

In this scenario, unsecured DNS entries enabled identity relay spoofing. Strengthening SPF, DKIM, and DMARC directly addresses the root cause and prevents recurring forged message injections. This is a clear eradication measure aimed at eliminating the exploitation pathway.

Options A and B relate to review and analysis phases. Option C supports threat intelligence sharing but does not remediate the internal DNS weakness.

Therefore, strengthening SPF, DKIM, and DMARC configurations is the appropriate eradication strategy.

James ' s activities, including creating anonymous access to cloud services to carry out attacks such as password and key cracking, hosting malicious data, and conducting DDoS attacks, exemplify the abuse and nefarious use of cloud services. This threat involves exploiting cloud computing resources to conduct malicious activities, which can impact the cloud service provider as well as other users of the cloud services. This abuse ranges from using the cloud platform ' s resources for computationally intensive tasks like cracking passwords or encryption keys to conducting DDoS attacks that can disrupt services for legitimate users.

Access point monitoring is the technique that helps incident handlers to detect man-in-the-middle (MitM) attacks by continuously observing and managing the wireless access points (APs) within a network. This includes identifying unauthorized or new APs attempting to connect to the network or mimic existing APs, even if they present similar IP and MAC addresses to legitimate access points. Through access point monitoring, incident handlers can quickly identify and mitigate spoofed APs, thus preventing MitM attacks that exploit wireless networks by intercepting and manipulating communications.
