CS0-003 Exam Dumps : CompTIA CyberSecurity Analyst CySA+ Certification Exam

Brady should be prioritized for remediation, as it has the highest risk score and the highest number of affected users. The risk score is calculated by multiplying the CVSS score by the exposure factor, which is the percentage of systems that are vulnerable to the exploit. Brady has a risk score of 9 x 0.8 = 7.2, which is higher than any other system. Brady also has 500 affected users, which is more than any other system. Therefore, patching brady would reduce the most risk and impact for the organization. The other systems have lower risk scores and lower numbers of affected users, so they can be remediated later.

D (4: HTTPS traffic to an external IP - 5.29.1.5)

The log entry shows an internal system (172.16.1.30) communicating with an external IP (5.29.1.5) overTCP 443 (HTTPS)usingBrowser.exe.

HTTPS traffic to an unknown external IP could indicate data exfiltration, as attackers often use encrypted channels to disguise stolen data transfers.

G (7: FTP traffic to an external backup server - bank.backup.com)

The log entry indicates that an internal machine (172.16.1.25) is transferring data tobank.backup.comusingFTP (port 21)andFileZilla.

FTP is a major concern because it is an outdated, unencrypted protocolthat can be exploited for data exfiltration. If unauthorized, this could be a serious data breach.

Other Options:

A (ARP traffic) → Not a concern(Just address resolution)

B (RPC Kerberos traffic) → Normal for authentication

C (SMB traffic) → Internal file sharing

**E (DNS traffic) → Common, though could be exfiltration in some cases, but not in this log)

F (WUS traffic) → Appears to be Windows Update Service traffic, likely legitimate

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.
