Cisco Firepower Ransomware

What Is Ransomware?

Ransomware is a sort of malicious software, often known as malware, that encrypts data and holds it hostage. It encrypts the data of a victim until the attacker receives a predefined ransom payment. A cryptocurrency like bitcoin, or another kind of cryptocurrency, is typically demanded by the attacker in exchange for payment. Only after that would the attacker send a decryption key, which will allow the victim’s data to be retrieved.

Recently, a lot of ransomware versions have arrived on the market, which we’ll go over in more depth below. Also covered will be the methods through which you may safeguard your system against future threats.

How does ransomware work?

What is the mechanism through which ransomware operates?
Ransomware is often distributed through a few key distribution channels, which are listed below. Email phishing, malvertising (malicious advertising), and exploit kits are examples of such attacks. The ransomware encrypts chosen files after it has been deployed and tells the victim of the need to pay the demanded ransom. View a video demonstration of a ransomware assault.

How do I protect myself from ransomware?

Back up all your data

You can power down the endpoint, restore it from a recent backup, and then restart it if you suspect an attack has taken place. You’ll be able to access all of your information while also preventing the ransomware from spreading to other systems.

Patch your systems

Make it a habit to update your software regularly. Many assaults can be thwarted by patching third-party software that is frequently exploited.

Educate users on attack sources

The human element is frequently the weakest link in the security chain. Inform your users about whom and what they can rely on. Educate them on how to avoid falling prey to phishing or other frauds.

Protect your network

Take a layered approach, with security being injected across the system, from the endpoint to the email to the DNS layer and beyond. Invest in next-generation firewalls (NGFWs) and intrusion prevention systems (IPSs) to protect your network (IPS).

Segment network access

Reduce the number of resources that an attacker has access to. Keeping access under tight control at all times helps to ensure that your entire network does not become a victim of a single attack.

Keep a close eye on network activity

Being able to observe everything that is going on across your network and data center can assist you in identifying assaults that are taking place beyond the perimeter. Add a layer of protection to your local area network by establishing a demilitarized zone (DMZ) (LAN).

Prevent initial infiltration

The majority of ransomware infections are spread through malicious email attachments or malicious downloads. Protect against dangerous websites, emails, and attachments by employing a layered security approach and file-sharing software that has been approved by management.

Arm your endpoints

Antivirus solutions installed on your endpoints are no longer sufficient. Configure rights so that they may conduct duties such as allowing access to the necessary network shares or granting user permissions on endpoints, among other things. The use of two-factor authentication will also be beneficial.

Gain real-time threat intelligence

Recognize your adversary. Talos, for example, provides threat intelligence that may be used to better comprehend security information and new cybersecurity threats.

Say no to ransom

Never, ever give in to the demands of the ransom. There is no guarantee that you will be able to recover your data, and you will merely be encouraging crooks to launch other attacks.
