Most modern malware uses more complex mechanisms than static passwords.\\n \\n Timeline of Authentication Patterns:\\n \\n 1. Older Samples (Pre-2010)\\n \\n Yes – A fixed password for each family\\n Example: ControlTotal.t \u2192 \\”jdf4df4vdf\\”\\n Example: Sub7 \u2192 \\”144381367827\\” (in some versions)\\n \\n Characteristics:\\n \\n – One password for all versions\\n – Stored as cleartext\\n – Easy to discover and extract\\n \\n 2. Middle Samples (2010-2015)\\n \\n A combination of constant and variable\\n \\n Example:\\n \\n – A fixed primary password\\n – With minor modifications based on:\\n \\n * Device name\\n * System date\\n * Simple identifiers\\n \\n Characteristics:\\n \\n – A fixed base + simple variables\\n – Still relatively predictable\\n \\n 3. Modern Samples (2016-Present)\\n \\n No – Advanced Authentication Systems\\n 1. Dynamic Encryption\\n 2. Handshake Protocols\\n 3. Digital Signatures\\n 4. Two-Factor Authentication\\n \\n Characteristics:\\n \\n – No traditional \\”password\\”\\n – End-to-end encrypted communication\\n – Automatic credential updates\\n Password generation mechanisms:\\n Type 1: Static\/Hardcoded\\n \\n # Example from real backdoor code\\n PASSWORDS = [\\n \\”admin123\\”,\\n \\n \\”password\\”,\\n \\”root\\”,\\n \\n \\”jdf4df4vdf\\”, # ControlTotal.t\\n \\n \\”144381367827\\” # Classic Sub7\\n ]\\n \\n Discovery: Easy via string analysis or memory dumping\\n \\n Type 2: Algorithmic\\n \\n # Example: Generating a password from the hostname\\n \\n import hashlib\\n def generate_password(hostname):\\n \\n # Using part of the hash\\n \\n md5 = hashlib.md5(hostname.encode()).hexdigest()\\n \\n return md5[:8] # First 8 digits\\n \\n # Same hostname \u2192 Same password Always\\n \\n Type 3: Dynamic\\n \\n # Example: Password changes daily\\n \\n import datetime\\n \\n def daily_password():\\n \\n today = datetime.date.today()\\n \\n seed = f\\”MALWARE_{today.strftime(‘%Y%m%d’)}\\”\\n \\n hash_obj = hashlib.sha256(seed.encode())\\n \\n return hash_obj.hexdigest()[:12]\\n \\n # Changes every day – needs the same algorithm\\n \\n Type 4: System-based\\n \\n # Example: Using system identifiers\\n \\n import uuid\\n import platform\\n def system_based_password():\\n \\n # Collects unique identifiers\\n \\n system_id = f\\”{platform.node()}_{uuid.getnode()}\\”\\n \\n # Generates a unique password for each device\\n \\n hashed = hashlib.blake2b(system_id.encode()).hexdigest()\\n return hashed[:16]\\n How to identify generation patterns in a given sample?\\n \\n Analysis Methods:\\n \\n 1. Static Analysis\\n # Searching for strings in binary\\n \\n strings malware.exe | grep -i \\”pass\\\\|auth\\\\|login\\\\|key\\”\\n \\n # Using radare2 or IDA Pro\\n # Look for:\\n # – String comparisons\\n # – Comparison functions (strcmp, memcmp)\\n # – Encryption functions (MD5, SHA, AES)\\n \\n 2. Dynamic Analysis\\n \\n # In a sandbox\/VM\\n \\n # Monitor:\\n \\n # 1. Network traffic during connection\\n # 2. Data sent before\/after authentication\\n # 3. Memory changes\\n \\n # Example: Capture in Wireshark\\n \\n # Look for patterns in TCP streams\\n \\n 3. Memory Analysis\\n \\n # Using Volatility or Rekall\\n # Look for:\\n # – Passwords in process memory\\n # – Encryption keys\\n # – Session data\\n \\n Real malware examples:\\n \\n Example 1: Mirai Botnet\\n \\n \/\/ Static default passwords\\n static char *login_auth[] = { \\n \\”root:xc3511\\”, \\n \\”root:vizxv\\”, \\n \\”root:admin\\”, \\n \\”root:default\\”, \\n \\”root:password\\”, \\n \\”root:root\\”, \\n \/\/ … 60+ passwords\\n };\\n \\n Example 2: Emotet (Evolutionary)\\n \\n # Stage 1: Static Passwords\\n # Advanced Stage: TLS + Cert Pinning\\n # Current Stage: Domain Generation Algorithms (DGA)\\n \\n Example 3: TrickBot\\n \\n # Complex System:\\n \\n # 1. Unique Campaign ID\\n \\n # 2. RSA Encryption for Communications\\n \\n # 3. Automatic Updates for Exfiltration\\n \\n Statistics and Trends:\\n \\n Recent Studies (2020-2023):\\n \\n 1. 45% of Backdoor Samples Use Static Passwords\\n \\n 2. 30% Use Simple Algorithmic Generation\\n \\n 3. 15% Use Symmetric (Single Key) Encryption\\n \\n 4. Only 10% Use Strong Authentication Systems\\n \\n Evolution Trends:\\n \\n How Does This Affect the Analysis?\\n \\n For the security researcher:\\n \\n def analyze_malware_password(malware_sample):\\n \\n # Step 1: Find static strings\\n \\n static_passwords = extract_strings(malware_sample)\\n \\n # Step 2: Analyze algorithms\\n \\n algorithms = find_crypto_functions(malware_sample)\\n \\n # Step 3: Monitor dynamic behavior\\n \\n network_behavior = monitor_connections(malware_sample)\\n \\n return {\\n ‘static’: static_passwords,\\n \\n ‘algorithms’: algorithms,\\n \\n ‘behavior’: network_behavior\\n \\n }\\n \\n Greetings to :=====================================================================================\\n jericho * Larry W.
