Ransom.Spora is Malwarebytes’ detection name for a ransomware application that will encrypt files on a victim machine and demand payment to retrieve the information. Ransom.Spora uses a combination of RSA and AES encryption to lock victim files. Spora doesn’t change filenames nor adds extensions, but rather each file is encrypted with a separate key to increase the decryption complexity.
Ransom.Spora may run silently in the background during the encryption phase and not provide any indication of infection to the user. Ransom.Spora may prevent the execution of Antivirus programs and other Microsoft Windows security features and may prevent system restoration as a means to solicit payment. Ransom.Spora may display a warning after successful encryption of the victim machine.
Ransom.Spora may be distributed using various methods. This software may be packaged with free online software, or could be disguised as a harmless program and distributed by email. Alternatively, this software may be installed by websites using software vulnerabilities. Infections that occur in this manner are usually silent and happen without user knowledge or consent.
Systems affected by ransomware are rendered unusable due to files that are typically used for regular operations being encrypted.
Affected users who choose to pay the threat actors behind ransomware campaigns in exchange for access to data may find that they don’t get their files back. There is also no sure way to know that threat actors will honor their end of the deal after paying the ransom.
Affected users who chose to pay the threat actors may also find themselves likely targets for future ransomware campaigns.
Data held hostage that wasn’t given back to users or deleted after the ransom has been paid can be used by threat actors either to (a) sell on the black market or (b) create a profile of the user they can use for fraud.
Malwarebytes protects users from the installation of Ransom.Spora by using Anti-Ransomware technology.
Malwarebytes can detect and remove Ransom.Spora without further user interaction.
Take note, however, that removing this ransomware does not decrypt your files. You can only get your files back from backups you made before the infection happened.
You can use the Malwarebytes Anti-Malware Nebula console to scan endpoints.
Choose the Scan + Quarantine option. Afterwards you can check the Detections page to see which threats were found.
On the Quarantine page you can see which threats were quarantined and restore them if necessary.
