Fantom Virus – Infection Spread

The new variant of the Fantom ransomware is possible to spread in several ways. Spam emails are the most probable way to be used in the spreading of the virus. A spam email is usually comprised of a brief description which tries to sound convincing that is of huge importance. Also, victims in most cases fall for the trick of opening an attached file, which supposedly reveals more information or has something useful inside. Those attachment files might look harmless, but upon opening, such a file could drop the payload of the virus and infect your whole PC.

Social media websites or file-sharing networks might be used to further spread this Fantom ransomware variant. The cybercriminals could have put a file containing a malicious script on these networks. Opening the file will release the payload for the ransomware, and your system will get infected. A tip to prevent that from happening is avoiding any suspicious emails, links, and files. When you are about to open a file you just downloaded, check its signatures first, along with its size and scan it with a security program. You can read more ransomware prevention tips in our forum.

Fantom Virus – Technical Description

The Fantom crypto-virus is back with a new variant. The new string of code for the Fantom ransomware was discovered by the malware researchers from the MalwareHunterTeam.

After infection, the payload file will create files on your computer which will launch a fake update. You can view that fake Windows update screen down here:

stf-fantom-ransomware-crypto-virus-locked-extension-protonmail-windows-update-fake-configuration-of-updates

The screen will be locked and not allow any interaction with it or other windows. If you see that screen, know that your files are in the process of being locked in the background. You might be able to close the screen using the Ctrl + F4 key combination. That will not stop the encryption process from going. The screen even has a percentage counter to fake the spike in activity of your disk drives and best imitate an update.

Next, the Fantom ransomware can create entries in the Windows Registry, which allow it to auto-launch with the start of the Windows Operating System. To support that, the ransomware does not encrypt any files which have the following extensions:

→.sys, .dll, .exe, .ico, .link, .locked, .purge, .frozen, .tmp, .temp, dll, ini, manifest, .com, .prx, .bin, .am, .dlm, .ngr

The following folders will also be ignored and all files inside them will remain unscathed:

→APPDATA, ProgramData, ProgramFiles, WINDOWS, APPDATA, Appdata, Application Data, intel, nvidia, Program Files, Program Files x86, Windows, RECYCLER, Recycle.Bin, Recycler, TEMP, Temp, Microsoft, RECYCLE.BIN

After encrypting the rest of the files set in the ransomware code, a picture with the ransom payment instructions will be placed on your desktop:

The ransom note is changed and looks more professional:

The newly-found Fantom ransomware also does not set a price for paying the ransom, as its previous version. Again it claims to delete your files from its servers after a while – this time the deadline is set to one week. However, the criminals behind it have improved and now use a more secure message system, involving the ProtonMail encrypted e-mail service:

Do NOT contact these cyber crooks about decryption. No guarantee there is in the world that you will get your files unlocked and as you can see from this article, they will keep making more ransomware. Giving money to them to unlock your files, and later that money to be used to lock your files again, including those of somebody else, is a viscous circle.

The new version of the Fantom ransomware encrypts an even bigger amount of files compared to its predecessor. The ransomware searches to encrypt files with 1,296 extensions. The list is gigantic, so we put it inside the following drop-down window:

Extensions List

All encrypted files will have the same extension appended to them, which is .locked. The ransomware is believed to use the RSA-2048 encryption algorithm. The public and private keys differ. The private key doesn’t seem to be in the code of the malware sample, according to the MalwareHunterTeam and the ransomware may be deemed not decryptable.

There are not that many detections of the new Fantom variant on VirusTotal:
