The target in a phishing attack is the endpoint, which is the device or system that the user interacts with, such as a computer, smartphone, or tablet. Phishing attacks aim to steal or damage sensitive data by deceiving people into revealing personal information like passwords and credit card numbers, or clicking on malicious links or attachments that can install malware on the endpoint. Phishing attacks can be delivered through various channels, such as email, phone, or text message, but they all rely on social engineering techniques to manipulate the user’s trust and curiosity. By compromising the endpoint, attackers can gain access to the user’s accounts, files, network, or other resources. Therefore, endpoint security is essential to prevent phishing attacks and protect the user’s data and identity. References:

Data is sent out to the attacker during a DNS tunneling attack as part of the domain name. DNS tunneling is a technique that encodes the data of other protocols or programs in DNS queries and responses. The attacker registers a domain, such as badsite.com, and points it to a server under their control, where a tunneling program is installed. The attacker infects a device with malware, which sends DNS queries to the attacker’s server, using subdomains of badsite.com to encode the data. For example, the malware could send a query for 1234.badsite.com, where 1234 is the encoded data. The attacker’s server decodes the data from the subdomain and sends back a DNS response, which may also contain encoded data in the answer section12. The other options are not correct, because they do not use the domain name to encode the data. The UDP/53 and TCP/53 packet payload and header are used to transport the DNS query and response, but they are not modified by the tunneling technique. The DNS response packet contains the answer to the query, but it is not the only way to send data to the attacker3. References:

Posture is a service in Cisco ISE that checks the compliance of endpoints with corporate security policies before allowing them to connect to the network. Posture policies define the requirements that endpoints must meet to be compliant, such as having antivirus software installed and updated, or having a specific registry key value. If an endpoint is compliant, Cisco ISE can apply a Change of Authorization (CoA) to grant it access to the network resources. CoA is a mechanism that allows Cisco ISE to dynamically change the authorization attributes of an existing session, such as VLAN, dACL, or SGT, without requiring the user to reauthenticate. CoA can be triggered by various events, such as posture assessment results, profiling changes, or manual actions by the administrator. CoA can also be used to quarantine or disconnect non-compliant endpoints. Therefore, ensuring that an endpoint is compliant with a posture policy configured in Cisco ISE provides the benefit of allowing CoA to be applied if the endpoint status is compliant. References :=

A Simple Custom Detection List is a feature of Cisco AMP for Endpoints that allows administrators to create a list of SHA-256 hashes of files that they want to detect, block, and quarantine on their endpoints. The list can be applied to a policy and the connectors will synchronize with the latest changes. However, the list only works with the exact SHA-256 hashes that are provided, and it does not detect any variations or modifications of the files. Therefore, if the malicious file abc428565580xyz.exe has been altered in any way, such as by changing its name, size, or content, the Simple Custom Detection List will not be able to recognize it as a threat. To ensure detection of the malicious file, the administrator must upload the SHA-256 hash of the current version of the file to the Simple Custom Detection List, or use another method that can detect file variations, such as an Advanced Custom Detection List or Cisco Threat Grid. References :=
