How to protect your business from ransomware attacks
Ransomware is one of the biggest threats to businesses: an attack can encrypt all your files and demand a ransom to restore access. The good news is that most attacks can be prevented.
What ransomware is
Ransomware is a type of malicious software that encrypts data on computers and servers, making it unusable. Attackers then demand money (usually in cryptocurrency) for the decryption key — with no guarantee you will get it.
How ransomware enters a company
Most often through:
- Infected emails with dangerous attachments or links (phishing);
- Weak or reused passwords;
- Outdated software with known vulnerabilities;
- Insecure remote access connections.
A single wrong click by an employee can be enough to infect the whole network.
Essential protection measures
- Automated, isolated backup: with a safe, tested backup, the attack can no longer blackmail you — you restore data and move on.
- Antivirus and firewall, updated and centrally managed.
- Two-factor authentication (2FA) on all important accounts.
- Security updates applied on time.
- Employee training to recognize phishing emails.
The golden rule: backup
The best protection against ransomware is an isolated, encrypted and regularly tested backup. We recommend the 3-2-1 rule: three copies of your data, on two types of media, one of them off-site. Read more about backup for businesses.
What to do if attacked
Do not pay the ransom — you have no guarantee of recovering your data and you encourage the attackers. Immediately isolate affected systems, disconnect them from the network and call specialists. With a good backup, recovery is possible without major losses.
