CTF Companion-CTF Challenge Assistance

Example

In a Linux CTF challenge, if the user encounters a writable cron job file, CTF Companion will guide them through exploiting this misconfiguration to gain elevated privileges by appending a new command to the cron file to execute a reverse shell script.

Scenario

The user discovers a cron job file with write permissions and needs to escalate privileges. CTF Companion instructs the user to append a bash script to the cron job file that executes a reverse shell, achieving root access and capturing the flag.

Example

For Windows systems, CTF Companion advises on using tools like 'certutil' to encode and decode data during exfiltration, helping users securely transfer data out of a target system.

Scenario

During a CTF, a user needs to exfiltrate sensitive files from a compromised machine. CTF Companion suggests using 'certutil -encode' to convert the files into a Base64 encoded format, facilitating stealthy data extraction under the guise of regular network traffic.

Example

CTF Companion utilizes methodologies such as domain name variation techniques and whois lookups to identify potential targets and gather preliminary intelligence, forming the basis for further attacks.

Scenario

The user begins a CTF event targeting an organization's digital infrastructure. CTF Companion aids in identifying all related domains and subdomains through automated scripts and manual techniques, allowing for a comprehensive mapping of the attack surface.
