The privilege escalation hacking tool KrbRelayUp is a wrapper that can streamline the use of some features in Rubeus, KrbRelay, SCMUACBypass, PowerMad/ SharpMad, Whisker, and ADCSPwn tools in attacks. Although this attack won’t function for Azure Active Directory (Azure AD) joined devices, hybrid joined devices with on-premises domain controllers remain vulnerable.

Amplification attacks are one of the most common distributed denial of service (DDoS) attack vectors. These attacks are typically categorized as flooding or volumetric attacks, where the attacker succeeds in generating more traffic than the target can process, resulting in exhausting its resources due to the amount of traffic it receives.

Web skimming campaigns now employ various obfuscation techniques to deliver and hide the skimming scripts. It’s a shift from earlier tactics where attackers conspicuously injected the malicious scripts into e-commerce platforms and content management systems (CMSs) via vulnerability exploitation, making this threat highly evasive to traditional security solutions.
