How Hackers Breach Networks and Demand a Ransom.
- Reconnaissance (Information Gathering)
- Hackers research their target using open-source intelligence (OSINT), scanning public databases, social media, LinkedIn, and company websites.
- They scan for exposed services, misconfigured cloud storage, weak credentials, and outdated software using tools like Shodan, Censys, and Nmap.
- Initial Access (Gaining Entry)
Hackers use multiple methods to gain access:
- Phishing Attacks: Sending emails with malicious attachments or links.
- Exploiting Vulnerabilities: Using known exploits like ProxyShell, Log4Shell, or unpatched VPN vulnerabilities.
- Brute Force & Credential Stuffing: Guessing weak passwords or using leaked credentials from previous data breaches.
- Malicious USB or Dropper Malware: Gaining entry through physical access or insider threats.
- Privilege Escalation & Lateral Movement
- After gaining initial access, hackers escalate privileges using Kerberoasting, Pass-the-Hash, or exploiting misconfigured permissions.
- They move laterally within the network using Remote Desktop Protocol (RDP), PowerShell, or Mimikatz to find critical systems.
- Persistence (Maintaining Access)
- Hackers create backdoors using scheduled tasks, registry modifications, or installing rootkits.
- They set up remote access tools like Cobalt Strike, AnyDesk, or TeamViewer.
- Exfiltration (Stealing Data)
- Before encrypting files, hackers steal sensitive data like customer records, financial data, or intellectual property.
- They use rclone, WinSCP, or PowerShell scripts to upload stolen data to their servers.
- Encryption (Deploying Ransomware)
- Once data is stolen, ransomware is deployed across the network.
- Hackers use PowerShell scripts, Group Policy Objects (GPO), or scheduled tasks to spread ransomware quickly.
- Popular ransomware families include LockBit, BlackCat, and Conti.
- Ransom Demand & Extortion
- A ransom note appears demanding cryptocurrency (Bitcoin or Monero) in exchange for decrypting files.
- Hackers threaten to publish stolen data if the ransom isn’t paid (double extortion).
- Payment or Recovery
- Companies either pay the ransom (which is risky) or restore from backups (if they have one).
- If backups were deleted, businesses face huge losses.
How to Prevent These Attacks
- Enable Multi-Factor Authentication (MFA) for all accounts.
- Patch vulnerabilities in OS, VPNs, and software.
- Use endpoint security with Next-Gen AV & EDR.
- Restrict RDP & PowerShell usage.
- Backup data offsite & test recovery plans.
- Train employees to detect phishing.
