Ransomware is malware that encrypts a victim’s data and demands a ransom to decrypt it. Ransomware attacks are becoming more sophisticated and cause major damage to individuals and organisations alike. To protect yourself from these dangerous attacks, effective anti-ransomware software is essential. Bitdefender has emerged as one of the best solutions available.
How the attack model has changed:
Ransomware attacks used to be opportunistic, focused on infecting quickly and making money quickly. Today, they are more sophisticated and carried out by organised cybercrime groups. The common model now is profit-sharing, where ransomware developers sell the malware to other criminal groups, who then carry out the attacks and share the proceeds.
The stages of a ransomware attack:
- Initial access: attackers usually use phishing email, exploit vulnerabilities or supply-chain attacks to get into the victim’s network.
- Staging: once inside, the attacker moves through the network, escalates privileges and establishes persistent access.
- Expansion: the attacker uses tools to move laterally across the network, identifying and encrypting important data.
- Extortion: the attacker encrypts the victim’s data and demands a ransom to decrypt it. Attackers may use other threats such as data leaks or denial-of-service (DDoS) attacks to force the victim to pay.
Techniques used:
- Living off the Land (LOL): attackers use tools and commands built into the victim’s operating system to avoid detection.
- Double/triple extortion: the attacker not only encrypts data but also threatens to leak it or carry out other attacks if the ransom is not paid.
- Supply-chain attacks: the attacker targets the victim’s third-party suppliers to get into their network.
How to prevent ransomware:
- Back up data regularly and make sure it can be restored.
- Update software and operating systems regularly.
- Use a strong network security solution and enable the firewall.
- Train staff on ransomware threats and how to spot phishing email.
- Have a ransomware incident response plan.
