Detection Based on Data Traffic

By scrutinizing network traffic for irregular timestamps and data volume changes, this approach can detect possible ransomware attacks. Nonetheless, it can sometimes generate false positives, disrupting legitimate operations.

Detection by Data Behavior

Monitoring unexpected changes in file storage locations and heightened file encryption activities helps identify ransomware attacks. This technique is robust against false alarms and limits the spread of attacks once identified.

Deception-Based Detection

Creating a pseudo network with decoy files can confuse ransomware by directing it toward fake data and identifying attacker methods, such as exploiting weak passwords or compromised endpoints.

Responding to Ransomware

Follow this step-by-step guide to respond effectively when a ransomware attack occurs, mitigating data loss and disruption to your organization.

Step 1: Activate Your Incident Response Plan

  • When a ransomware attack strikes, your first line of defense is a well-coordinated incident response plan. 
  • Kickstart your strategy for containing, isolating, and responding to the ransomware incident.

Step 2: Separate Altered Systems

Ransomware Recovery Methods: How to Choose?

Unfortunately, no one is entirely resistant to ransomware, and it is predicted that ransomware attacks will occur every two seconds by 2031.

So, it’s not a matter of “if” but “when” you’ll get hit. Therefore, it’s crucial to have a well-thought-out ransomware recovery procedure in place.

Depending on your needs, there are several effective methods to consider for a swift recovery after an attack.

Prompt Initial Response

The response time is critical to limit the impact of a ransomware attack. As the initial step, immediately disconnect all vulnerable devices from your network to halt the propagation of the attack and prevent further damage.

Once done, report the attack to the appropriate authorities, such as the local police or trusted platforms like On Guard Online

Your prompt action aids in identifying the attacker’s modus operandi and target selection process, ultimately preventing other organizations from falling victim to the same ransomware invasion.

Immutable Backups

One of the most effective defenses against ransomware attacks is restoring your data from immutable backups that are unchangeable and resistant to modification. 

These backups provide a clean and secure copy of your files, allowing you to bypass the need to negotiate with cybercriminals and pay the ransom.

When selecting a backup solution, evaluate factors such as the volume of data requiring backup, desired backup frequency, and budget constraints. Options include manual backups and automated cloud-based services to ensure you find the right fit.

Windows System Restore

Windows System Restore is an integrated feature that empowers you to roll back your system to a previous state, encompassing files, programs, and settings. 

It can help recover files encrypted by ransomware by restoring them to a point before the encryption occurs. However, it may not recover personal files or work if the ransomware has infected your computer’s restore points.

Nonetheless, understanding and utilizing Windows System Restore can enhance your recovery from ransomware and increase the likelihood of retrieving vital documents.

Decryption Tools

Ransomware decryption tools aim to decode files encrypted by ransomware, allowing users to regain access to their valuable data without meeting the financial demands of the attackers.
