While conducting a covert penetration test on a UNIX-based infrastructure, the tester decides to bypass intrusion detection systems by sending specially crafted TCP packets with an unusual set of flags enabled. These packets do not initiate or complete any TCP handshake. During the scan, the tester notices that when certain ports are probed, there is no response from the target, but for others, a TCP RST (reset) packet is received. The tester notes that this behavior consistently aligns with open and closed ports. Based on these observations, which scanning technique is most likely being used?
If executives are found liable for not properly protecting their company’s assets and information systems, what type of law would apply in this situation?
During a security audit, a penetration tester observes abnormal redirection of all traffic for a financial institution’s primary domain. Users are being redirected to a phishing clone of the website. Investigation shows the authoritative DNS server was compromised and its zone records modified to point to the attacker’s server. This demonstrates total manipulation of domain-level resolution, not cache poisoning or client-side attacks. Which technique is being used in this scenario?
A financial services firm is experiencing a sophisticated DoS attack on their DNS servers using DNS amplification and on their web servers using HTTP floods. Traditional firewall rules and IDS are failing to mitigate the attack effectively. To protect their infrastructure without impacting legitimate users, which advanced mitigation strategy should the firm implement?
