Mobile Remote Access Trojans (RATs) are highlighted in CEH v13 Mobile Platform Hacking as one of the most dangerous threats. Once installed, a mobile RAT provides attackers persistent, covert access to devices, allowing screen capture, keystroke logging, microphone activation, and data exfiltration.

Unlike MitM or clickjacking, RATs operate post-compromise, often disguised as legitimate apps. Jailbreaking is detectable via integrity checks, but RATs can remain hidden even on non-rooted devices.

CEH v13 emphasizes that RATs bypass traditional defenses, including antivirus and MDM, making them extremely difficult to detect. Hence, Option C is correct.

Risk Mitigation

Risk mitigation can be defined as taking steps to reduce adverse effects. There are four types of risk mitigation strategies that hold unique to Business Continuity and Disaster Recovery. When mitigating risk, it’s important to develop a strategy that closely relates to and matches your company’s profile.

Risk Acceptance

Risk acceptance does not reduce any effects; however, it is still considered a strategy. This strategy is a common option when the cost of other risk management options such as avoidance or limitation may outweigh the cost of the risk itself. A company that doesn’t want to spend a lot of money on avoiding risks that do not have a high possibility of occurring will use the risk acceptance strategy.

Risk Avoidance

Risk avoidance is the opposite of risk acceptance. It is the action that avoids any exposure to the risk whatsoever. It’s important to note that risk avoidance is usually the most expensive of all risk mitigation options.

Risk Limitation

Risk limitation is the most common risk management strategy used by businesses. This strategy limits a company’s exposure by taking some action. It is a strategy employing a bit of risk acceptance and a bit of risk avoidance or an average of both. An example of risk limitation would be a company accepting that a disk drive may fail and avoiding a long period of failure by having backups.

Risk Transference

Risk transference is the involvement of handing risk off to a willing third party. For example, numerous companies outsource certain operations such as customer service, payroll services, etc. This can be beneficial for a company if a transferred risk is not a core competency of that company. It can also be used so a company can focus more on its core competencies.

Types of Password Attacks - Active Online Attacks: Internal Monologue Attack Attackers perform an internal monologue(獨自) attack using SSPI (Security Support Provider Interface) from a user-mode application, where a local procedure call to the NTLM authentication package is invoked to calculate the NetNTLM response in the context of the logged-on user.Attacker disables the security controls of NetNTLMv1, extracts all the non-network logon tokens from all the active processes to masquerade as legitimate users.

Comprehensive and Detailed Explanation:

SIEM (Security Information and Event Management) systems aggregate logs and alerts from across the network—servers, routers, firewalls, IDS/IPS, and applications—and correlate that data to identify suspicious or malicious activity.

They provide:

Real-time alerting

Long-term log storage

Compliance reporting

Incident response facilitation
