Spora Ransomware Description

The Spora ransomware is a newly discovered malware family that will probably take on popularity by spawning new variants. The core threat contains a lot of features that are not typical of other ransomware and this is why it it important to know all and understand how damaging it can be.

The Spora ransomware is written in the C programming language and packed using an UPX executable packer. A major distinction between this and other ransomware families is that it doesn’t rename the affected files using a specific extension. The virus employs a powerful AES + RSA encryption engine which targets specific target user files and extorts the victims for a ransomware payment.

Depending on the victim’s geographical location the virus creates a different ransom note according to the following pattern:

  • USXXX-XXXXX-XXXXX-XXXXX.HTML – for victims located in the United States of America.
  • RUXXX-XXXXX-XXXXX-XXXXX.HTML – for victims located in Russia
  • FRXXX-XXXXX-XXXXX-XXXXX.HTML – for victims located in France.

Other country code prefixes are used depending on the location. A typical Spora ransomware note contains the following message:

SPORA rANSOMWARE
All your work and personal files were encrypted
To restore data, obtaining guarantees and support, follow the instructions in your account.
Personal Area
xxxxs: //spora.bz>
USXXX-XXXXX-XXXXX-XXXXX
What happened?
1. Only we can restore your files.
Your files have been modified using RSA-1024 algorithm. Reverse recovery process is called decryption. This requires your unique key. Choose or “hack” it is impossible.
2. Do not turn to intermediaries!
All recovery keys stored only in our country, respectively, if you someone will offer to restore the information, in the best case, he first buys the key here, then you will sell it at a premium.
If you can not find your Sync Key

The Spora ransomware deletes all Shadow Volume Copies of the affected machine which prevents data recovery. This is done using the following command:
vssadmin.exe delete shadows /all /quiet

In addition it disables the Windows Startup Repair and changes the BootStatusPolicy which is a serious system modification by issuing the following commands:

bcdedit.exe /set {default} recoveryenabled no
bcdedit.exe /set {default} bootstatuspolicy ignoreallfailures

The virus’s engine also scans for popular security software and employs several stealth detection techniques to install itself to the target host. It is able to harvest important system information.

Each infected user is greeted with a gateway crafted page which uses the TOR anonymous network. Each host receives their own unique victim ID which allows the computer users to buy their own dedicated private decryption key.

The criminals who operate the Spore ransomware allow for several payment “packages” that have a different price depending on the service offered:

  • FULL RESTORE – Fully restores the affected files.
  • IMMUNITY – Guarantees immunity from malware.
  • REMOVAL – Removes the malicious payload from the system.
  • FILE RESTORE – Restores individual files.

The security experts have noticed that the gateway page also has a built-in live chat function which allows the victims to communicate with the virus operators. It was observed that they have answered in a prompt and timely manner.

Spora Ransomware Distribution

The first Spore ransomware samples were identified in the beginning of January 2017. This is a multi-language computer threat which is used to attack various individuals and companies worldwide.

Primary infection methods include spam email campaigns and infected software bundles. They usually carry the binary payload which contains the dangerous Spora ransomware.

Right now a major email spam campaign is underway which uses phishing tactics to infect hosts. The Spora ransomware is contained in messages that pose as coming from 1C, a very popular accounting software used in Russia and other former USSR countries. The subjects and contents pose as containing invoices and some example file names include Экспорт из 1С.a01e743_рdf.hta which translates to “Scan-copy _ 10 Jan 2017”. They use double extensios to trick the user into thinking that the file is an actual document file.

Other distribution techniques include malicious ads, browser hijackers and exploit kit attacks. Spora ransomware strains have been identified on various forums and other types of online communities. The virus is usually found in files that use the following naming patterns:

  • special_phrase_in_English.random_chars_pdf.hta
  • специальная_фраза_на_русском.random_chars_pdf.hta
  • random.hta
