Ransomware: An Invisible Threat

Ransomware is a type of malicious software that hijacks data from computers and information systems, demanding payment in exchange for releasing all the files. It is one of the biggest cyber threats facing businesses today and it has become increasingly common with successful attacks.

Ransomware attacks often start with a phishing email that contains a virus link or attachment. When the user clicks on this link or on the attachment, ransomware is installed on the computer, blocking access to files and requesting payment in exchange for the decryption key.

These attacks can be devastating as companies rely on their data to carry out daily activities and therefore can be brought to a complete standstill. Data is encrypted, making it inaccessible, and operations are stopped. In addition, hackers order the payment in bitcoin or other cryptocurrency. The result can be lost revenue, damage to the company's reputation and even bankruptcy.

Ransomware Example

Ransomware attacks are a serious threat to individuals and organizations, and the best way to help and minimize the effects is to adopt robust security practices. Are they:

  • Regularly back up files that cannot be lost, keeping copies in safe places disconnected from the network. It enables data recovery to be effective in cases of attack.

  • Frequently conduct cybersecurity awareness training for employees.

  • Keep your security software up to date, including your antivirus and firewall programs. Cyber criminals often exploit vulnerabilities in outdated software.

  • Limit access to confidential information to only those employees who need it to perform their jobs.

  • Use a reliable VPN network when connecting to public Wi-Fi networks. This will ensure that the information is encrypted and protected from interception.

  • Always stay informed about cybersecurity threats and stay alert for signs of malicious activity on your computer, smartphone or tablet.

  • Configure email filters to block phishing and spam messages.

  • Do not open emails from suspicious or unknown senders as they tend to be used to distribute malware including ransomware.

Additionally, it is important for companies to have an incident response plan in place to deal with ransomware if an attack occur. This plan should include data backup and recovery procedures, isolation of the affected network and communication with stakeholders, ensuring business continuity.

Finally, the threat of ransomware is constantly evolving and as a serious cyber problem, it has a significant impact on individuals and businesses. Against this type of attack then, the best defense is a comprehensive security strategy such as:

  • Regular backups;

  • User education;

  • Proactive detection and response;

  • Cybernetic resilience posture.

While paying the ransom seems like the easiest option in ransomware attacks, it only serves to encourage hackers to continue their activities. Companies must resist the temptation to make such payments, and seek other alternatives so that data and systems can be restored.
