Ransomware Attack: How To Protect from Ransomware

What Is A Ransomware Attack?

Ransomware is a type of malicious software that encrypts your digital files or blocks your network. When infected with a ransomware system, it searches and encrypts important files using an asymmetrically encrypted key, so the attacker only has the private key to encrypt the files. As a result, the network attacker may ask ransomware to decrypt the files or restore network access.

Ransomware victims are asked to pay a ransom using text files containing random messages or commands. Payments can range from a few hundred to thousands of dollars because crypto must always be paid in crypto. Ransomware is big business for cybercriminals because they lost $ 5 billion in 2017 alone due to ransomware attacks.

How To Protect from Ransomware

Data Backup

Make backup copies of your data. The best way to avoid the risk of being locked out of your critical files is to make sure you always have backups in your cloud and on your external hard drive.

This way, if you get a ransomware infection, you can uninstall your computer or device for free and install the files from the backup. It protects your data and does not entice you to reward malicious authors by paying a ransom. Backups do not block but reduce the risk.

Secure your backup

Make sure your backup data is not available for modification or deletion of data storage systems. Ransomware tries to back up and encrypt or delete data, so use backup systems that do not allow direct access to backup files.

Security Software keep update

Protect with best security software to all your devices. and make sure that software must be up to date.  Make sure you update your devices’ software early and often, as patches for flaws are typically included in each update.

Practice Complete Safe Surfing

Be careful where you click any link. Don’t reply to emails, text messages, and fax from a computer from people you don’t know, and only download apps from trusted sources. This is important because malware authors often use social technology to try to install your dangerous files.

Use only secure networks.

Avoid using public Wi-Fi networks, as most of them are vulnerable and can be monitored by cybercriminals. Instead, set up a VPN that provides a secure connection to the Internet wherever you are.

Follow the path

Stay up to date with the latest ransomware threats so you know what to look for. If you are infected with ransomware and do not make backup copies of your files, be aware that tools are available from technology companies to help victims.

Security Program

Provide regular maintenance training to everyone in your organization to avoid fishing and other engine conflicts. Do exercises and tests regularly to make sure your workout is on track.

Ransomware Targets

Many cyber security experts agree, from small businesses to celebrities, everyone is the target of the ransomware program. Some popular targets of these attacks are:

Health care – Many hospitals and medical devices use legacy software, which makes it relatively easy to disrupt. Hospitals are a favourite target for cybercrime because they are critical facilities. After all, hospital authorities pay more ransom to save the lives of patients.

Government agencies – Government agencies are important and have very sensitive data. Therefore, these agencies are a popular target for ransomware attacks because they are less likely to lose sensitive data.

Mobile devices – Access to mobile payments, personal media files and credentials in online services are common microdata found on shared phones, which is a popular ransomware program.

Academic Institutions – Academic institutions are the primary target of extortion programs for their research, intellectual property and student financial information.

Human Resources Departments – Human resources systems have personal and financial records that make them the primary target of ransomware attacks.

Why is Ransomware spreading?

To Spread Ransomware it has several reasons:

  • Easy access to malware kits that you can use to create new malware templates on demand.
  • Use the most popular public commenters to build cross-platform ransomware (e.g. Ransom32 uses a Node.js file with JavaScript loaded)
  • Use new technologies such as encrypting the entire drive, not individual files.
  • Modern thieves don’t need technology. The ransomware market is starting to grow over the Internet and offers additional benefits to malware developers who demand reductions in malware strains and blackmail revenues from all types of cybercrimes.
