Rhysida ransomware is a new and emerging threat that businesses need to be aware of. The group first appeared in May 2023 and has since targeted a variety of organizations, including healthcare. In some cases, this has caused hospitals to have to close their doors for days or even weeks while they recover from the attack.
Rhysida ransomware is delivered through a variety of methods, including phishing emails, malicious attachments, and exploit kits. Once it is installed on a system, Rhysida will encrypt all of the files on the computer, making them inaccessible to the victim. The attackers then demand a ransom payment in exchange for the decryption key.
Rhysida ransomware is particularly dangerous because it also steals data from the victim's computer before encrypting it. This means that even if the victim pays the ransom, the attackers may still release the stolen data to the public.
The attacks carried out by Rhysida ransomware are becoming increasingly sophisticated. The group is now using a variety of techniques to evade detection, including:
- Using a variety of attack vectors, such as phishing emails, malicious attachments, and exploit kits
- Using advanced encryption techniques that make it difficult to decrypt files without the ransom key
- Stealing data from the victim's computer before encrypting it
- Threatening to release the stolen data to the public if the ransom is not paid
There are a number of things that businesses can do to protect themselves from Rhysida ransomware. These include:
- Educating employees about phishing attacks. Employees are often the weakest link in a company's cybersecurity defenses. By educating employees about phishing attacks and how to spot them, businesses can significantly reduce their risk of being targeted by ransomware.
- Using a BDR solution. A BDR solution can help businesses quickly recover from a ransomware attack by restoring data from a backup. This can be critical for businesses that cannot afford to be down for long periods of time.
- Keeping software up to date. Software updates often include security patches that can help protect against ransomware. By keeping software up to date, businesses can reduce their risk of being infected with ransomware.
In addition to the above, businesses can also protect themselves from Rhysida ransomware by:
- Making secure offsite backups.
- Running up-to-date security solutions and ensuring that your computers are protected with the latest security patches against vulnerabilities.
- Restrict an attacker's ability to spread laterally through your organization via network segmentation.
- Using hard-to-crack unique passwords to protect sensitive data and accounts, as well as enabling multi-factor authentication.
- Encrypting sensitive data wherever possible.
- Reducing the attack surface by disabling functionality which your company does not need.
- Educating and informing staff about the risks and methods used by cybercriminals to launch attacks and steal data.
