Cyber Security Challenges

Break the custom encryption algorithm and decrypt the hidden message. The flag is the decrypted text.

Perform a comprehensive security assessment of a mobile application (Android/iOS). The assessment includes: 1) Static analysis of application code, 2) Dynamic analysis using runtime manipulation, 3) Network traffic analysis, 4) Reverse engineering of obfuscated code, 5) Exploitation of mobile-specific vulnerabilities, 6) Bypass of security controls like certificate pinning and root detection.

Compromise a multi-cloud environment (AWS, Azure, GCP) with proper security controls. The challenge involves: 1) Initial access through misconfigured S3 buckets, 2) Privilege escalation using IAM misconfigurations, 3) Lateral movement across cloud services, 4) Container escape techniques, 5) Data exfiltration while evading cloud security tools. Demonstrate cloud-specific attack techniques.

Analyze a sophisticated malware sample that uses multiple evasion techniques including: 1) Anti-analysis and anti-debugging, 2) Code obfuscation and packing, 3) Network communication with C2 servers, 4) File system and registry manipulation, 5) Process injection and persistence mechanisms. Provide a complete analysis report including IOCs, behavior analysis, and mitigation recommendations.

Penetrate a simulated industrial control system network. The network contains PLCs, HMIs, and SCADA systems. You need to: 1) Map the network topology, 2) Identify vulnerable ICS protocols (Modbus, DNP3, IEC 61850), 3) Exploit PLC vulnerabilities, 4) Manipulate industrial processes, 5) Demonstrate impact on physical systems. This challenge requires knowledge of OT security.

A client has lost access to their Bitcoin wallet. The wallet file is encrypted and you need to recover the private key. The wallet uses AES-256 encryption with a password that was generated using a specific pattern. You have access to the encrypted wallet file and some clues about the password generation method. This challenge involves cryptographic analysis, password cracking, and blockchain forensics.

Simulate an Advanced Persistent Threat attack. You need to: 1) Perform reconnaissance and OSINT gathering, 2) Exploit initial access through phishing simulation, 3) Establish persistence and lateral movement, 4) Escalate privileges to domain admin, 5) Exfiltrate sensitive data. This is a comprehensive red team exercise.

Use social engineering techniques to extract sensitive information from the target. The flag is the obtained secret.

Capture and crack the WPA2 handshake to obtain the network password. The flag is the password.

Reverse engineer the Android APK and find the hardcoded API key. The flag is the discovered key.

Exploit vulnerabilities in the IoT device firmware to gain root access. The flag is the root password.

Analyze the memory dump and find evidence of malicious activity. The flag is the discovered malware name.

Connect to the SSH server using the credentials: bandit0:bandit0. Find the password for bandit1 stored in a file called "readme".

Exploit multiple vulnerabilities in the web application to gain admin access. Chain different attack vectors.

Reverse engineer the binary to find the secret key. The binary uses obfuscation techniques.

Exploit the vulnerable C program to gain shell access. The binary has ASLR disabled and no stack canaries.

Investigate the provided social media profile and find the hidden information. The flag is the discovered secret.

Exploit the directory traversal vulnerability to read the /etc/passwd file and find the admin user.

Find the hidden message in the provided image file. The flag is the hidden text.

Analyze the provided PCAP file and find the hidden message. The flag is the decoded message.

Find a way to bypass the login form and extract the admin password. The login form is vulnerable to SQL injection.

Find the hidden file in the directory structure. The flag is the filename of the hidden file.

Crack the MD5 hash: 5d41402abc4b2a76b9719d911017c592

The password for the next level is stored in a file called "-" located in the home directory. Read this file.
