What Is Ransomware?

Ransomware is a type of software created by hackers to steal and encrypt essential data from users. As the name suggests, attackers demand a ransom in money in exchange for a "unique key" to unlock the encrypted files.

A ransomware attack can start when the user downloads a corrupted file that spreads through all the OS.

To infect files, hackers use methods like:

  1. Files or attachments
  2. Exploit kits through unsecured websites
  3. Corrupted downloads
  4. Targeting system's weaknesses

Once the malicious software is in the system, it will begin scanning through all the information it deems valuable. After it finds something, it will lock the file and create a unique key. If the user clicks on the file, a pop-up will generate, saying they need to pay to recover it.

Email Attachments

In 2019, ransomware from phishing emails increased by 109%. Hackers' most preferred methods to trick users into downloading ransomware are sending files containing PDFs, ZIPs, Word Documents, and Excel spreadsheets.

Once the victims download the attachment, the ransomware can start working immediately. Depending on the malware's configuration, it may take days, weeks, or even months before the malware shows itself.

Remote Desktop Protocol (RDP)

Microsoft created RDP as a means to help users troubleshoot their computers remotely. However, cybercriminals have taken advantage of this feature and used it to their advantage. 

Hackers exploit this software by using brute-force attacks or pretending to be employees for Microsoft and then ask people for personal information. Once they have the data, they can disable the firewall and antivirus to implant files maliciously

Security Weaknesses

If you are a business owner, you need to watch for new software patches the day they come out; don't wait months years. If you don't, hackers will exploit the lack of security.

How To Prevent Ransomware

Backup All Information

The beauty of immutable backups is that they cannot be altered or changed. This type of backup is ideally essential for malware and ransomware attacks or unforeseen events. 

In case you fall victim to a ransomware attack, an immutable backup can save you from:

  • Going out of business.
  • Paying the ransom.
  • Hackers' encrypting your data.

It's good practice to back up your data multiple times a day to safeguard your data optimally. Keep at least one backup file offline to ensure hackers didn't infect it. And if the attacker was successful in infecting your devices with ransomware, you need to reset your OS and restore it with the last clean backup you have saved.

Hire Full-Time IT Team

If you are not sure how to optimize your security, it's best to hire a specialized security team that guides you to protect your network's endpoints, including:

  • Desktops.
  • Tablets.
  • Laptops.
  • Mobile phones.

Ask them about the best practices in today's market to protect your data from cyber theft. They can help you determine which devices you use are a potential entry point for ransomware. They will protect these devices from hackers by:

  • Checking if devices have the latest software.
  • Black-listing websites and apps.
  • Educate employees when they visit a risky website.

Hire a professional team like Systems X to get an IT advisory so you can rest assured all your valuable information is being protected.

Automatically Update Computers

Setting automatic updates can save you a lot of manual work and time. Also, keeping software up to date with the latest updates and patches can ensure optimal protection of:

  • Firewalls/Antiviruses
  • Intrusion detection and prevention system (IDPs).
  • Anti-malware programs.
  • Software from 3rd parties
  • Endpoint protection.
  • Apps.
  • Firmware.
  • Operating systems.

Don't forget that hackers are constantly implementing new methods to steal your information. Waiting too long before you update your system can put your business at serious risk of being exploited.

Install Firewall/Anti-virus

When it comes to protecting your information, a firewall is an excellent tool for deflecting ransomware attacks. They scan and help the security team monitor any signs of malicious payloads. Firewalls can also allow the security team to watch what comes in and out of your computer. 

To best support your firewall defenses, consider setting up:

  • Threat hunting.
  • Active tagging of workloads
  • Regular examination of traffic for critical software or services

Your firewall should be able to run a deep (automatic) packet inspection (DPI) scan to examine all the data stored in your computer. This capability can potentially identify infected files.

Limit Personal Device Use in Office

When employees use their devices without regulations during the office, this can pose unnecessary risks to your network. You can write a new policy that outlines how and when employees can use a device if they need to. Also, make sure that work devices and personal devices don't share the same Wi-Fi network to avoid risks. 

Encourage Secure Password

Set a meeting with your team and review the importance of having a solid password. The average user uses passwords that are easy to guess. Passwords like abc123 or 123456 are pretty standard. 

Remember, all it takes is a single employee who doesn't follow guidelines to put the company at risk. Hackers know this, and they often start exploiting these weaknesses because employees are not taking security seriously enough.

Ensuring that all employees have strong passwords that they update regularly is one of the best security practices. If they don't, cybercriminals can breach your system with a simple brute-force attack.

Another great practice is to use a second-step authentication service. This way, you are ensuring that the right person is accessing the correct information. 

Section Off Office

Once ransomware enters your system, the malware moves from device to device in your network until it finds the targeted data. Sectioning off the office can prevent infiltrators from freely moving through operating systems. 

Make sure each subsystem connected to the network is:

  • Equipped with individual security controls.
  • Following the policy access guidelines.
  • Separated from the firewall and gateway.

If an intruder gains access to a part of your network, sectioning off prevents them from succeeding in the attack. Since the attackers need time to break into each segment, sectioning off will give the security team time to identify and isolate the threat.

Run Security Checks

Running regular security checks can help in determining the degree of vulnerability the system has. These assessments enable you to inspect the IT environments for system exploits, such as:

  • Weak passwords.
  • Authentication services.
  • Misconfigurations in the system.
  • Flaws in accounts.
  • Enabling backdoor programs.
  • Unpatched firewalls, apps, and OSs.
  • Database errors that allow SQL injections.

Consider organizing a penetration test if you want to know how well prepared your team is against a ransomware attack. These types of tests can help you see how well your system and staff react to imminent threats. 

Install Ad Blockers

A reputable ad blocker will help protect you and your loved one's privacy on the internet. They prevent sites from collecting your data and selling it to others. If you constantly surf the web, installing an adblocker is a great way to keep your and your loved ones' information safe online.

They also ensure all employee devices and browsers have plug-ins and extensions that automatically block pop-up ads. Much of the malicious software installed is when users click on an ad redirecting them to an unsecured site. Malicious marketing is a common ransomware source. Getting a paid ad blocker is a simple way to limit the number of attacks your company will deal with.

Get Management On Board

The management team is the one who organizes your business's protection against unwanted cybercriminals. If it's related to cyber threats, intrusions, malware, and other types of data breaches, a cybersecurity risk management team is the one who can determine what step to take next. 

There are many responsibilities that a cyber security manager needs to handle while on the job. Here is a list of the most common tasks a cyber security manager does:

  • They are responsible for safeguarding physical, digital, and intellectual information
  • They actively monitor security vulnerabilities.
  • They are constantly working to anticipate new security threats. They stay up-to-date with new infrastructures.
  • They manage annual budgets to align the companies needs with information about the company's security.
  • They implement procedures to monitor and ensure security patches for an agency's systems to be up-to-date.
