Ransomware Attacks: How To Prevent It, Types & History

Cyberattacks, especially ransomware attacks, are becoming increasingly common and costly in a computerized culture. As companies become more dependent on digital infrastructure and data, protecting your business from cyber threats is crucial. This page discusses ransomware attacks, including prevention methods, its history, and the many types of ransomware that have evolved.

Protecting Your Business from Cyber Threats

Let’s first stress the need to safeguard your company from online dangers before delving into the specifics of ransomware assaults. A strong cybersecurity strategy is now essential, given the volume and sophistication of assaults on the rise. Here are some crucial measures your company may take to safeguard itself:

  • Employee Training:  Inform your staff on cybersecurity best practices, such as how to spot phishing emails and the risks associated with downloading dubious files.
  • Regular Updates: To fix vulnerabilities that hackers could exploit, keep all software, operating systems, and antivirus products up to date.
  • Data Backup: Backup your data often to secure offline places. Having a backup means you may recover your systems without paying a ransom in the event of a ransomware attack.
  • Network Security: To protect your network, set up powerful firewalls, intrusion detection systems, and access controls.
  • Incident Response Plan: To effectively respond to a cyber attack if it occurs, create and test an incident response strategy.

History of Ransomware Attacks

Since the late 1980s, ransomware has encrypted and locked victims’ data until they pay a ransom. Ransomware has a distinguished history. However, ransomware attacks have become more frequent and intricate over the previous decade.

The AIDS Trojan launched the first ransomware attack in 1989. It demanded a ransom to a Panamanian post office box and propagated through floppy disks. Fast forward to 2013, when CryptoLocker ransomware used advanced encryption to cause havoc. Victims have a limited time to pay the Bitcoin ransom to get the decryption key.

Types of Ransomware

Ransomware has evolved, with cybercriminals developing new variants to maximize their ill-gotten gains. Here are some common types:

CryptoLocker: Ransomware like CryptoLocker is ancient and notorious. Users must pay a ransom to access their files. It encrypted many files on affected devices when it initially emerged in 2013. Usually, it spreads via malicious email attachments or hacked websites. CryptoLocker demanded Bitcoin ransoms and threatened to delete the victim’s data if the ransom was not paid within a set timeframe. After law enforcement dismantled CryptoLocker, other ransomware variants have arisen.

WannaCry: In May 2017, WannaCry infected hundreds of thousands of PCs in 150 countries, making headlines. It exploited the Windows bug EternalBlue, which was claimed to have been designed by the NSA but leaked by a hacker group. WannaCry wanted Bitcoin for victims’ data. After a given period, the ransom would be forfeited, and the victim’s files erased forever. WannaCry shows the devastating power of ransomware, even if a security researcher uncovered a “kill switch” that halted its spread.

Ryuk: Ryuk ransomware is known for its sophistication and operators’ thorough reconnaissance before unleashing ransomware. Ryuk often enters a network and moves laterally to reach crucial systems. Ryuk will encrypt data and demand a large Bitcoin ransom after acquiring access. The Ryuk perpetrators have been linked to Bitcoin theft and other cybercrimes.

Sodinokibi (REvil): Another malware that steals data and encrypts it is REvil. It initially appeared in 2019 and quickly became known for targeting enterprises with sensitive data. Like Maze, Sodinokibi operators threaten to release stolen data if the ransom is unpaid. Sodinokibi assaults frequently start with remote desktop service or software weaknesses.

Preventing Ransomware Attacks

Many factors would help you to protect your business from cyber threats. Ransomware encrypts data and demands a payment to unlock it. This damages your finances and reputation. A detailed look at some of the most critical ransomware prevention measures:

  • Regular Employee Training and Awareness: Staff should get regular ransomware training. Teach students to spot phishing emails, harmful links, and malware-laden attachments. Well-informed employees are your first protection against ransomware assaults.
  • Use Reliable Security Software: Buy malware and virus protection software. Keep it updated to protect you from the latest malware. These solutions can detect and stop ransomware before it infects your machines.
  • Regular Software Updates and Patch Management: Regular software upgrades and patch management are vital because old software often includes security holes that fraudsters might exploit. Using an effective patch management system, maintain the latest operating systems, applications, and security software. Regular updates can close security gaps and reduce ransomware assaults.
  • Email Security Measures: Use anti-phishing filters and email authentication standards like DMARC, SPF, and DKIM to secure your emails. These approaches can detect and stop ransomware-laden phishing emails.

Conclusion

Protecting your business from cyber threats is crucial to business continuity and cybersecurity in today’s difficult internet world. Understanding ransomware’s history, types, and prevention methods may greatly reduce your risk of falling victim to this deadly cybercrime. Remember that prevention is the best medicine, and investing in cybersecurity today may save your firm from costly and devastating ransomware assaults. Always stay alert and safe.
