RANSOMWARE

Ransomware is a type of malicious software (malware) that encrypts a victim's files, systems, or networks, making them inaccessible. The attackers then demand a "ransom" payment, typically in cryptocurrency, in exchange for a decryption key that would supposedly restore access to the data.

First of all, let's go to set up the windows7 machine to explain the ransomware, for it we have to go to settings and we should activate Nat as you can see in below.

Now, we have to create files which will be encrypt with the ransomware as you can see  in the both pictures below.

In addition, we must go to web browser and search this URL which is where we have to search Tesla crypt as you can see below and we can see other link:

• https://github.com/ytisf/theZoo
• https://github.com/Da2dalus/The-MALWARE-Repo

Now, we have to download the zip as you can see below.

In the next step we have to extract the file but we need a password which is infected.

Before  executing the virus we have to quit the Nat because, we don't want to deploy around the network as you can see below which the Not attached configuration.

Now we can  extract the ransomware which the password which is infected.

In this step we should use in the first file the extension .exe.

Now if we execute the file, we shouldn't be able to be access important files as you can see in the second picture below.

Ransomware Remediation and Prevention Strategies
Ransomware attacks can be devastating, so a multi-layered approach focusing on both prevention and rapid remediation is essential.
Prevention (Stopping Attacks Before They Happen):
Regular Data Backups (and 3-2-1 Rule):
Description: This is your strongest defense. Regularly back up all critical data to an external drive or cloud storage.
3-2-1 Rule: Keep 3 copies of your data, on 2 different storage types, with 1 copy kept off-site/offline (air-gapped). This prevents ransomware from encrypting your backups.
Why it helps: If attacked, you can wipe your systems and restore from clean backups without paying the ransom.
Software Updates and Patching:
Description: Keep your operating systems (Windows, macOS, Linux), web browsers, antivirus software, and all other applications updated to the latest versions.
Why it helps: Attackers often exploit known vulnerabilities (bugs) in outdated software. Patches fix these weaknesses.
Strong Endpoint Protection (Antivirus/Anti-malware/EDR):
Description: Use reputable antivirus, anti-malware, and Endpoint Detection and Response (EDR) solutions on all your devices. These tools can detect and block malicious activity.
Why it helps: They provide real-time protection against known ransomware variants and can often detect suspicious behavior even from new, unknown threats.
Email Security and User Awareness Training:
Description: Be extremely cautious with emails, especially those with attachments or links from unknown or suspicious senders. Never click on suspicious links or open unverified attachments.
Why it helps: Phishing emails are a primary delivery method for ransomware. User education is crucial to recognizing and avoiding these traps.
Multi-Factor Authentication (MFA):
Description: Enable MFA for all online accounts, especially for critical systems and remote access. This requires a second form of verification (like a code from your phone) in addition to a password.
Why it helps: Even if an attacker steals your password, they can't access your account without the second factor.
Network Segmentation:
Description: Divide your network into smaller, isolated segments. Restrict traffic between these segments.
Why it helps: If ransomware infects one segment, it will be harder for it to spread laterally to other critical parts of your network.
Principle of Least Privilege:
Description: Grant users and systems only the minimum necessary permissions to perform their tasks. Avoid giving administrative rights unnecessarily.
Why it helps: This limits the damage ransomware can do if an account is compromised, as it won't have widespread access.
Disable Macros by Default:
Description: Many ransomware strains are delivered via malicious macros in Microsoft Office documents. Configure Office to disable macros by default or only allow digitally signed macros.
Why it helps: This significantly reduces a common attack vector.
Web Filtering and DNS Security:
Description: Block access to known malicious websites and enforce safe Browse policies. Use DNS security services to prevent connections to command-and-control servers.
Why it helps: Prevents users from accidentally downloading malware or connecting to attacker infrastructure.
Remediation (Responding After an Attack):
Isolate Infected Systems:
Description: Immediately disconnect any infected devices from the network (unplug Ethernet cables, disable Wi-Fi).
Why it helps: This prevents the ransomware from spreading to other computers or network shares.
Incident Response Plan Activation:
Description: Have a pre-defined and tested incident response plan. This plan should outline roles, responsibilities, communication strategies, and technical steps for containment, eradication, and recovery.
Why it helps: A clear plan ensures a swift, coordinated, and effective response, minimizing downtime and damage.
Secure Evidence and Notify Authorities:
Description: Collect logs, ransom notes, and any other indicators of compromise for forensic analysis. Notify relevant law enforcement agencies (e.g., local police, cybercrime units) and cybersecurity authorities.
Why it helps: Evidence can help in understanding the attack, identifying the perpetrators, and potentially aiding recovery efforts. Reporting helps authorities track and combat cybercrime.
Do NOT Pay the Ransom (Generally Recommended):
Description: While tempting, paying the ransom offers no guarantee of data recovery and encourages further attacks. It also funds criminal organizations.
Why it helps: Relying on robust backups and recovery strategies is the preferred approach.
Identify and Remove the Ransomware:
Description: Use your endpoint protection tools or specialized ransomware removal tools to identify and remove the malicious software from all affected systems.
Why it helps: Ensures that the threat is no longer active on your systems.
Restore from Clean Backups:
Description: Once systems are clean, restore your data from your secure, uninfected backups.
Why it helps: This is the most reliable way to recover your data without paying the ransom.
Post-Incident Review and Strengthen Defenses:
Description: After recovery, conduct a thorough analysis of how the attack occurred. Identify weaknesses in your security posture and implement stronger controls to prevent future incidents.
Why it helps: Learn from the incident to improve your overall cybersecurity resilience. This includes updating policies, improving training, and investing in new security technologies.
