Security Classification Information Type: General Information Severity level: 🟡 Low to moderate Direct Impact: Limited Exploitability: Medium (in certain contexts) ⚠️ Potential threats 1. Network Reconnaissance Description: The attacker can use this information to map the entire network architecture of the targeted services. What it does: Know all subdomains Identify potential entry points Planned Targeted Attacks Probability: 🟡 Medium 2. DNS (DNS-based Attacks) a) DNS Poisoning Scenario: 1. The attacker gets the list of domains 2. Sets up malicious DNS Server 3. Poisons the DNS cache 4. Redirects users to fake servers Possible targets: - slack.com → fake-slack-login.com - snapchat.com → phishing-snap.com Impact: Credential theft, account hacking Probability: 🟠 Medium to High b) DNS Tunneling Usage: - Data leakage via DNS queries - Bypass firewalls - Connect to C&C (Command & Control) servers 3. Phishing Campaigns Full scenario: Stage 1: Preparation - Extract Slack, Snapchat, Skype domains - Buy similar domains: • slack-notifications.com • snapchat-security.com • skype-verification.com Phase 2: Building Infrastructure - Clone login pages - Setting up email servers - Preparing databases for data collection Phase 3: Implementation - Send a "Security Alert" messages - Convincing victims to enter their login credentials - Harvest thousands of accounts Objectives: ✓ Corporate Employees (Slack) ✓ Social platform users ✓ Premium Accounts Expected Success Rate: 15-30% (Industry Statistics) What it does: Corporate Accounts Hacked Intellectual Property Theft Malware spread 4. Subdomain Takeover Technology: # Attack steps: 1. Extract all ranges from the file 2. Detecting subdomains: - sc-cdn.net - slack-edge.com - etsystatic.com 3. Search for Orphaned Domains: - CNAME refers to a service that does not exist - AWS S3 bucket deleted - Heroku app does not exist 4. Takeover: - Register the same service - Subdomain control - Hosting malicious content What it does: - Executing malicious JavaScript on the native domain - Cookies & Tokens Theft - Persistent XSS Probability of success: 🟠 10-20% of subdomains 5. Man-in-the-Middle (MITM) attacks Scenario: Environment: Public Wi-Fi (Cafe, Airport, Hotel) Stage 1: Preparation - Attacker creates a fake Wi-Fi access point - Uses the list of domains to set up DNS Spoofing Stage 2: Interception of communications - The victim connects to the fake network - Attempts to contact slack.com → are intercepted - Attacker presents a fake page Stage 3: Exploitation - Login credentials - Malware injection - Intercept of submitted files High-value goals: ✓ slack.com (Enterprise Communications) ✓ skype.com (video calls) ✓ playstation.com (Payment Information) 6. Distributed DDoS Attacks Strategy: Planning: - Select goals from the list of domains - Identify the least protected ranges - Build a botnet for attack Implementation: Attack Type: DNS Amplification Instructions: - Use open DNS servers - Send fake queries - 50-100x Motion Amplification Possible targets: - sndcdn.com (CDN for SoundCloud) - sc-cdn.net (CDN for Snapchat) - bdstatic.com (Baidu Static Content) What it does: - Disabling the service for millions of users - Huge financial losses - Defamation 🎯 Advanced Exploitation Scenarios Full scenario: Hack an organization via Slack 🎯 Goal: A major tech company uses Slack Phase 1: Reconnaissance ├─ Extract Slack Domains from File ├─ Find company employees on LinkedIn ├─ Collect email addresses └─ Name Pattern Analysis (@company-name.slack.com) Phase 2: Building Infrastructure ├─ Buy Range: slack-security-alert.com ├─ Clone Slack Login Page ├─ Set up an SSL certificate (Let's Encrypt) └─ Set up a server to collect data Phase 3: Initial Attack ├─ Sending phishing emails: │ "Your Slack workspace requires security verification" ├─ The employee clicks on the link ├─ Enters login details on the fake page └─ Attacker harvests data Phase 4: Expansion ├─ Login to Slack workspace ├─ Access to Secret Conversations ├─ Steal sensitive files ├─ Implanting Backdoors into Enterprise Systems └─ Lateral Movement Bottom Line: ✗ Full enterprise penetration ✗ Intellectual Property Theft ✗ Ransomware ✗ Millions of dollars in losses 🔬 Advanced Technical Analysis 1. ModifiedTime Analysis "modifiedTime": 1769039502278 Unix Timestamp Conversion const date = new Date(1769039502278); Result: Tue Jan 06 2026 (Approximately) Review: - Recently updated file - Indicates active maintenance - Possibility of adding new domains 2. iconUrl Pattern Analysis Pattern: https://icons.adtidy.net/icon?domain=X Conclusion: - File from AdGuard/AdTidy - Used in ad blocking apps - It may be from: • AdGuard Home • Pi-hole Custom Lists • DNS Filtering Solutions 3. Extract Insights from domainsList # Statistical Analysis From the Snapchat file: domains = [ "addlive.io", #WebRTC Service "feelinsonice.com", # Old Domain "sc-cdn.net", # Content Delivery "sc-corp.net", # Corporate "snapads.com" # Advertising Platform ] Conclusion: ✓ Snapchat has 12 domains ✓ Separates content, company, and ads ✓ Use multiple CDN (for performance) ✓ addlive.io = Video calling technology This can be exploited in: - CDN targeting instead of the main domain - Segregation of attacks by service - Exploiting legacy domains (feelinsonice.com) 🛡️ Recommended protection measures For Affected Companies 1. Secure DNS # DNSSEC Activation dnssec-keygen -a RSASHA256 -b 2048 -n ZONE example.com #CAA Records to prevent unauthorized SSL certificates example.com. CAA 0 issue "letsencrypt.org" example.com. CAA 0 issuewild ";" 2. Monitor similar domains # Typosquatting Monitoring Tool domains_to_monitor = [ "slack.com", "s1ack.com", # Pay attention to 1 instead of l "slak.com", "slack-login.com", "secure-slack.com" ] # Use services such as: # - DomainTools # - SecurityTrails # - Whoisology
