All CS0-003 Test Inside CompTIA Questions

A vulnerability that is related to a specific adversary campaign, with IoCs found in the SIEM, should have the highest priority for the mitigation process. This is because it indicates that the vulnerability is actively being exploited by a known threat actor, and that the organization’s security monitoring system has detected signs of compromise. This poses a high risk of data breach, service disruption, or other adverse impacts.

A rollback had been executed on the instance. If a database server is restored to a previous state, it may reintroduce a vulnerability that was previously fixed. This can happen due to backup and recovery operations, configuration changes, or software updates. A rollback can undo the patching or mitigation actions that were applied to remediate the vulnerability.

Weaponization is the stage of the Cyber Kill Chain where the attacker creates or modifies a malicious payload to use against a target. In this case, the disgruntled open-source developer has created a logic bomb that will act as a wiper, which is a type of malware that destroys data on a system. This is an example of weaponization, as the developer has prepared a cyberweapon to sabotage the code repository.

Cyber Kill Chain® | Lockheed Martin, which states: “In the weaponization step, the adversary creates remote access malware weapon, such as a virus or worm, tailored to one or more vulnerabilities.”

The Cyber Kill Chain: The Seven Steps of a Cyberattack - EC-Council, which states: “In the weaponization stage, all of the attacker’s preparatory work culminates in the creation of malware to be used against an identified target.”

What is the Cyber Kill Chain? Introduction Guide - CrowdStrike, which states: “Weaponization: The attacker creates a malicious payload that will be delivered to the target.”
