* Network-Based Scanner: Network-based scanners are those that interact only with the real machine where they reside and give the report to the same machine after scanning. * Agent-Based Scanner: Agent-based scanners reside on a single machine but can scan several machines on the same network. * Proxy Scanner: Proxy scanners are the network-based scanners that can scan networks from any machine on the network. * Cluster scanner: Cluster scanners are similar to proxy scanners, but they can simultaneously perform two or more scans on different machines in the network. 

It is a type of unvalidated redirect attack whereby the attacker first identifies the most visited website of the target, determines the vulnerabilities in the website, injects malicious code into the vulnerable web application, and then waits for the victim to browse the website. Once the victim tries to access the website, the malicious code executes, infecting the victim. 

In this scenario, the attacker used file-less malware to bypass the company's application whitelisting. File-less malware resides entirely in memory, making it difficult for antivirus software and IDS/IPS to detect. It can run in the context of a trusted process or system application, and can be delivered through various attack vectors, including phishing emails, malicious websites, or network exploits. 

DNS hijacking: Attacker modifies DNS queries/responses, redirects users to incorrect/malicious websites, steals sensitive information. 

In a session donation attack, the attacker donates their own session ID to the target user. In this attack, the attacker first obtains a valid session ID by logging into a service and later feeds the same session ID to the target user. This session ID links a target user to the attacker’s account page without disclosing any information to the victim. When the target user clicks on the link and enters the details (username, password, payment details, etc.) in a form, the entered details are linked to the attacker’s account. To initiate this attack, the attacker can send their session ID using techniques such as cross-site cooking, an MITM attack, and session fixation. A session donation attack involves the following steps. 

Obfuscating is an IDS evasion technique used by attackers to encode the attack packet payload in such a way that the destination host can only decode the packet but not the IDS. Using Unicode characters, an attacker can encode attack packets that the IDS would not recognize but which an IIS web server can decode.

The VRFY commands enables SMTP clients to send an invitation to an SMTP server to verify that mail for a selected user name resides on the server. The VRFY command is defined in RFC 821.The server sends a response indicating whether the user is local or not, whether mail are going to be forwarded, and so on. A response of 250 indicates that the user name is local; a response of 251 indicates that the user name isn't local, but the server can forward the message. The server response includes the mailbox name. 

FTPS includes full support for the TLS and SSL cryptographic protocols, including the use of server-side public key authentication certificates and client-side authorization certificates. It also supports compatible ciphers, including AES, RC4, RC2, Triple DES, and DES. It further supports hash functions SHA, MD5, MD4, and MD2.
