Ransomware has become a significant issue for businesses and organizations worldwide. In fact, there was a tenfold increase in ransomware assaults between 2018 and 2021. Businesses may spend thousands on state-of-the-art firewalls and other forms of cybersecurity to secure their IT infrastructure. However, an employee's accidental click may still bring the whole thing crashing down.
Cyber attackers rely on human mistakes. And they are equipped with complex social engineering tactics to fool workers. As a result, they evade the safeguards firms set up to infiltrate systems with deadly ransomware. Because of the risks it presents, businesses must be aware of how to defend themselves against ransomware.
To succeed in a battle, you must first know what you are fighting against. So this guide has everything you need to know about this harmful malware and how you can protect your data from it.
What is Ransomware?
Ransomware is complex software that infects computers and holds data or confidential information hostage until a charge, or "ransom," is paid. To extort money from victims, cybercriminals often utilize a binary encryption key to limit access to data.
Organizations like companies, schools, hospitals, and others depend on their data to operate regularly and are particularly vulnerable to ransomware attacks. In addition, the data captured may have the tendency to be lost or exposed permanently if the ransom is not paid.
Different Types Of Ransomware
No matter how big or small, any organization is fair game for ransomware hackers. This virus can potentially cause significant data leakage or expose private information from single files like papers or photographs to large databases. Here are the four types of ransomware:
Lockers: These prevent you from using your computer for anything except paying the ransom.
Encryption: The most frequent ransomware encrypts files, so you can't access them without a unique key.
Leakware or Doxware: If the fee isn't paid, doxware or leakware will expose sensitive data belonging to the victim or the business.
Scareware: Scareware is deceitful software that uses fear tactics to trick people into downloading and installing it. Occasionally, a user may be inundated with pop-ups and must pay a fee before accessing the site's content.
10 Things To Do to Protect Your Data from Ransomware Attacks
Knowing how to prevent ransomware and taking steps to establish the best practices will lessen the probability of being a target of the next ransomware assault. Here are the following ten practical ways to protect your data against ransomware attacks:
1. Establish strict systems and cybersecurity strategies.
Build a data breach response strategy to provide your IT security staff a road map to implement in the case of a cyberattack, such as ransomware. Protocols for confining the attack and protecting critical assets include gathering forensic evidence and determining the full extent of the damage. Furthermore, informing contractors and partners should all be included in the strategy.
2. Maintain a regular data backup schedule.
Always include data backups in your regular maintenance schedule. To prevent the ransomware from corrupting the backup data, save them to an external drive and remove them from the computer. After an attack, ensure your backups are safe to use by checking for infections.
3. Keep your business systems up-to-date.
To protect your business's network against ransomware, ensure that all your operating systems, programs, and apps are up-to-date with the latest patches. Unfortunately, companies with a history of carelessness in this area are especially susceptible to ransomware assaults.
4. Think before you click that link.
Phishing emails aren't the only suspect for spreading malicious links. Attackers may also use SMS messaging and social media platforms to disseminate them. In addition, strange messages may include links to harmful web pages. They will send them to your contacts if your account has been compromised.
The easiest way to defend yourself is to avoid opening any unexpected links. These links may come from someone you know personally, such as a family member or a coworker. Suppose you have doubts about the legitimacy of the link after checking it. In that case, the best move you can make is to contact the sender through another means of communication.
5. Strengthen your company's endpoints.
Take precautions to secure your systems' configuration. Safe setups may assist plug security flaws left by default settings and reduce your organization's vulnerability to cyber-attacks.
6. Systematize your desktop extensions.
Files with the.exe extension are a common target for hackers trying to penetrate company networks. Unfortunately, the default setting in Windows conceals file extensions, so a malicious file like "paycheck.doc.exe" might masquerade as a harmless Word document with the same name. However, you may avoid a ransomware assault with a bit of configuration change that always displays extensions.
7. Don't forget about your other devices.
The negative aspect of ransomware is that it affects more than desktop PCs. Computers running Mac OS X and mobile devices are not immune to ransomware attacks. Therefore, users of both gadgets must adhere to strict security measures.
In addition, people may link mobile devices to a wealth of resources. These include social media and information-packed applications. Because of this, they are the top targets for ransomware, and you should protect them just like any other network.
8. Limit user access.
Malware may spread rapidly and easily via an open network, contaminating all the devices and systems it comes into contact with. Ensure the users only have access to the resources needed to perform their job duties. If a breach does occur, the impact of the ransomware will be lessened by the restrictions placed on access.
9. Always be vigilant and watchful for suspicious activities.
Aside from preventative measures, regular monitoring is essential in the fight against ransomware. Security measures like anti-virus software, data backups, and employee education on the dangers of cyberspace are only the beginning of a protracted fight against ransomware.
Have your IT team help you establish a strategy for handling incidents. Determine the best measures to take if your company is attacked to limit the harm's extent. Also, maintain a heightened vigilance for any risks or unusual activity that might undermine the safety of your data. Use scanners and monitoring programs regularly to identify any malware lying in wait on your machine.
10. Schedule regular training sessions for cybersecurity.
Since negligence on the part of employees is the most prevalent source of ransomware attacks, everyone in the company must be well-versed in identifying the signs of intrusion. Additionally, hackers often use spear-phishing and phishing emails to trick targets into visiting malicious websites or opening malicious attachments. So, ensure you address established hacker tactics and emerging dangers in your cybersecurity training sessions.
