Ransomware is one of the most common and dangerous types of malware. In a ransomware attack, hackers gain access to your system and then encrypt your files. They demand a ransom in order to decrypt the files and make them accessible again.
If you don’t have a backup of your data, you may be tempted to pay the ransom. However, there’s no guarantee that the hackers will actually decrypt your files after you’ve paid. Additionally, paying the ransom may encourage hackers to target other businesses in the future.
Fortunately, there are steps you can take to protect your business from a ransomware attack. Keep reading to learn about the different types of ransomware and how to prevent them.
What is ransomware?
Ransomware is a type of malware that encrypts a victim’s files and demands a ransom be paid in order for the files to be decrypted and accessible again. It’s a growing threat to both individuals and businesses, with billions of dollars being lost each year to ransomware attacks.
Most Common Types of Ransomware
Crypto (or encryptors)
Crypto-ransomware is the most common type of ransomware; it encrypts victims’ files using strong cryptography and demands a ransom be paid in order for the files to be decrypted and accessible again. One well-known form of crypto-ransomware is the “Bitcoin blackmail scam,” where scammers demand that victims pay a ransom in Bitcoin in order for their files to be decrypted.
Lockers
Lock-ransomware is less common than crypto-ransomware but is just as dangerous. This type of ransomware locks victims out of their computers or devices entirely; often, the only way to regain access is to pay the ransom demanded by the attacker. In some cases, however, even if the ransom is paid, the attacker may not provide the victim with the key needed to unlock their device or computer.
Screen-lockers
Screen-locking ransomware is similar to lock-ransomware but instead of locking victims out of their devices entirely, it only locks them out of certain programs or applications. Attackers often use screen-locking ransomware to target specific programs or applications critical for businesses, such as accounting or customer relationship management (CRM) software. As with lock-ransomware, the only way to regain access is usually to pay the ransom demanded by the attacker; however, there is no guarantee that paying the ransom will result in regaining access to locked programs or files.
Scareware
Scareware is a type of malware that tricks users into thinking their computer is infected with a virus. It typically displays fake alerts or warnings that urge the user to take action, such as downloading a virus removal tool or calling a support number. Scareware can be very effective in scaring people into paying for bogus antivirus software, but it can also damage the computer if the user falls for the scam and downloads the malware.
Doxware/Leakware
Doxware is a type of ransomware that threatens to expose the victim’s personal or company information, or “dox,” if they do not pay the ransom. Doxware is often delivered as an attachment to an email, and the victim is typically given a short amount of time to pay the ransom before their personal or company information is released.
The Impact of Ransomware Attacks
Ransomware attacks can have a number of negative impacts on a business. First, they can result in the loss of valuable data, which may be irreplaceable. Second, they can cause considerable financial damage, as they may force businesses to pay a ransom in order to get their files back. Third, ransomware attacks can damage a company’s reputation, as news of an attack can spread quickly and may tarnish the business’ image. Finally, ransomware attacks can disrupt normal business operations, as employees may be unable to access critical files or programs.
How to Protect Your Business From Ransomware Threats
There are several steps you can take to protect your business from a ransomware attack:
- Back up your data regularly. If you have a backup of your data, you can recover from a ransomware attack without paying the ransom. Be sure to store backups offline so that the virus can’t encrypt them.
- Install antivirus software and keep it up-to-date. Antivirus software can detect and remove many common strains of ransomware before they have a chance to do any damage. Be sure to install software from a reputable vendor and keep it up-to-date with the latest security patches.
- Keep your software up-to-date. Outdated software is one of the most common targets for attackers. Be sure to install security updates as soon as they’re released.
- Train your employees in cybersecurity best practices. Your employees are one of your greatest assets when it comes to preventing attacks. Teach them about good password hygiene, how to spot phishing emails, and other cybersecurity best practices.
- Restrict access to critical systems and data. Only give employees access to the systems and data they need to do their jobs. This will minimize the spread of infection if malware does manage to get past your defenses.
- Don’t surf the web on public Wi-Fi networks. Public Wi-Fi networks are often unsecured and can be easily compromised by attackers. When accessing the internet on an unsecured network, always use a VPN to keep your data private.
- Consider investing in advanced security solutions. Advanced security solutions like next-generation firewalls, intrusion detection systems, and endpoint protection can add an extra layer of defense against attacks.
- Respond quickly if you do suffer an attack. If you do find yourself the victim of a ransomware attack, act quickly to contain the damage. Isolate infected computers, change passwords, and contact law enforcement if necessary.
Steps to Take After a Ransomware Attack
- Do not pay the ransom. If you find yourself the victim of a ransomware attack, do not pay the ransom. There is no guarantee that you will get your files back even if you do pay, and you may just be funding the criminal activities of the attacker. Instead, try to restore your files from the backup, or if that’s not possible, contact a data recovery specialist.
- Isolate the infected systems. If you find yourself the victim of a ransomware attack, one of your first steps should be to isolate the infected systems. This will help minimize the damage the virus can do and may help prevent it from spreading to other systems.
- Identify the source. Finding the source and entry point of the malware can help improve security practices and training for the company.
- Report the attack. If your business is the victim of a ransomware attack, report the attack to law enforcement. This will help investigators track down the criminals responsible and may help prevent future attacks.
How to Report a Ransomware Attack
- Contact your local FBI field office to request assistance or submit a tip online.
- File a report with the FBI’s Internet Crime Complaint Center (IC3).
Frequently Asked Questions About Ransomware
What is ransomware?
Ransomware is a type of malware that locks users’ files or computer systems until a ransom is paid. Ransomware can be very costly to businesses and may even shut down entire networks. In recent years, ransomware has become one of the most common forms of malware.
How do ransomware attacks work?
Most ransomware attacks start with a phishing email. The attacker sends an email that appears to be from a legitimate source, such as a bank, asking the user to open an attachment or click on a link. Once the user clicks on the link or opens the attachment, the ransomware is downloaded and begins to encrypt files on the system. The attacker then demands a ransom payment in order to decrypt the files. Ransomware can also be spread through malicious websites and software programs. Attackers often use exploit kits to probe systems for vulnerabilities and then install ransomware if they find one.
What are the different types of ransomware?
There are many types of ransomware, but the most common are encrypting ransomware and locking ransomware. Encrypting ransomware is the type that encrypts files on the system and locks the user out until a ransom is paid. Locking ransomware simply locks the user out of the system until a ransom is paid.
Can ransomware spread through Wi-Fi?
Yes, ransomware can spread through unsecured Wi-Fi networks. This is one of the ways that ransomware can often spread to multiple systems very quickly. Make sure to use a VPN when accessing the internet on public Wi-Fi networks to help protect your data.
Can ransomware be removed?
There is no one-size-fits-all answer to this question, as the removal process will vary depending on the type of ransomware. However, there are some steps you can take to try to remove ransomware from your system. First, try to restore your files from a backup. If that’s not possible, you can use ransomware removal tools that can help detect and remove ransomware from your system. Finally, make sure to keep your software up to date and install a good antivirus program to help protect your system from future attacks.
Should you pay the ransom?
No, you should not pay the ransom. There are a number of reasons for this. First, there is no guarantee that you will get your files back even if you do pay, and you may just be funding the criminal activities of the attacker. Instead, try to restore your files from the backup, or if that’s not possible, contact a data recovery specialist. Second, by paying the ransom, you are essentially encouraging the criminals to continue making these attacks. Finally, paying the ransom does not guarantee that you will get your files back and may actually lead to further financial losses.
