Educate your employees
Build a shared sense of responsibility inside your company. Explain to your employees how following simple rules can help a company avoid ransomware incidents. Create employee and operational control policies that cover aspects of network management and facilities, including password renewal regulations, incident handling, access control rules, protecting sensitive data and more.
Layered security in everything
Literally everything. Security means safeguarding all data touchpoints within your network, may it be via hardware devices or software platforms.
Update, update, update
It is essential to install all security updates as soon as they become available. Always update your operating system and software to eliminate recent vulnerabilities.
Use a ransomware tool
SMBs can also try a free Kaspersky Anti-Ransomware Tool for Business. Its recently updated version contains an exploit prevention feature to prevent ransomware and other threats from exploiting vulnerabilities in software and applications. It is also helpful for customers that use Windows 7: with the end of support of Windows 7, new vulnerabilities in this system won’t be patched by the developer.
DURING and AFTER A RANSOMWARE ATTACK
Unblock your computer; remove the malware
If you find your computer blocked — it won’t load the operating system — use Kaspersky WindowsUnlocker, a free utility that can remove a blocker and get Windows to boot.
Cryptors are a harder nut to crack. First, you need to get rid of the malware by running an antivirus scan. If you don’t have a proper antivirus on your computer, you can download a free trial version here.
Don’t pay, do report
Remember that ransomware is a criminal offense. Do not pay the amount the perpetrators is asking in exchange for your data. If you become a victim, report it to your local law enforcement agency.
Get your files back; look for a decryptor
If you have a backup copy of your files, you can simply restore your files from the backup. That is by far your best shot. If you haven’t made backups, you can try to decrypt files by using special utilities called decryptors. All of the free decryptors created by Kaspersky can be found at Noransom.kaspersky.com.
Other antivirus companies also develop decryptors. One thing: Be very sure you’re downloading these programs from a reputable website; otherwise you run a high risk of getting infected by some other malware.
Involve the experts
If the decryptor is not available online, contact your trusted cybersecurity vendor to check if they have a decryption tool for the ransomware that has attacked you.
