Kevin, a professional hacker, wants to penetrate CyberTech Inc’s network. He employed a technique, using which he encoded packets with Unicode characters. The company’s IDS cannot recognize the packets, but the target web server can decode them.
What is the technique used by Kevin to evade the IDS system?
Obfuscating is a technique where the attacker encodes the attack payload in a way that security systems like Intrusion Detection Systems (IDS) cannot recognize, but the target server can decode. In this case, Kevin encoded the packets with Unicode characters, which the IDS could not interpret, allowing him to evade detection and successfully target the web server.
C. Obfuscating. Explanation: Obfuscation is a technique used by hackers to hide their malicious activities from security systems, such as Intrusion Detection Systems (IDS). In this case, Kevin encoded the packets with Unicode characters to make them difficult for the IDS to recognize and understand. This technique is used to bypass security measures and gain access to a system undetected. However, the target web server can decode the packets, which allows Kevin to gain access to the system. Session splicing, urgency flag, and desynchronization are other techniques used by hackers to evade IDS systems, but they are not applicable in this scenario.
appreciate your answer and explanations
Perfect explanation!
C. Obfuscating CEH Book V12 Module 12 Page 1672 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.
