RemindMe Ransomware – How Is It Spread

So far, little is known about how RemindMe ransomware spreads but, research experts believe that it takes advantage of the carelessness in some users. The ransomware may use malicious URLs or files which it may advertise via:

The infected documents are usually Microsoft Office or Adobe .pdf documents which contain malicious macros that have exploit kits or other scripts written to drop the malicious .exe of RemindMe onto the user PC.

RemindMe Ransomware In Detail

At its initial state, the RemindMe ransomware may drop one or more files of the following file formats:

→ .exe; .dll; .tmp; .vbs; .bat; .cmd

The dropped files may have different names, and they are usually located in the most frequently targeted Windows key folders:

commonly used file names and folders

After the malicious data has been dropped onto the infected computer, the ransomware may execute an elevated privilege command in the Windows command prompt which may erase the shadow volume copies and the backup of the infected computer. The command is as follows:

→ vssadmin delete shadows /for={DrivePartition} [/oldest | /all | /shadow={Identification of the shadow copies}] [/quiet]

The ransomware may perform other activities such as set its executable that encrypts files or its ransom note files to run every time you start Windows by adding values to the following registry subkey:

→ “HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run”

After modifying the settings, the ransomware may execute a “call” script which could launch the executable which scans for the files to encrypted. The file types which RemindMe Ransomware is likely to encrypt are the most frequently used ones.(LINKKK)

The algorithms that may be used by this ransomware may vary, but the strongest and most often used ones are:

  • RSA cypher.
  • AES cypher.

After encrypting the files, RemindMe ransomware appends the .Remind file extension to the files, for example:

  • New Text Document.txt.remind

After encrypting the data, the ransomware leaves a ransom message, also known as a ransom note. The files that are reported by infected users are:

  • decypt_your_files.html
  • decypt_your_files

The ransom message by RemindMe is as follows:

→ “All your files have been encrypted with RemindMe Ransomware
Your unique GUID for decrypt:{custom identificator}
Send me some 2 bitcoin on addres: {cyberciminal’s payment account details}
After confirming the payment, all your files can be decrypted.
I you do not make payment within 5 days, you will lose the ability to decrypt them AND ALL YOUR FILES HAVE BEEN DELETED.
Make your Bitcoin Wallet on: {links to BitCoin wallet services}
How to buy/sell and send Bitcoin:
{links to instructions}
After the payment, send the wallet from which paid and your uniq ID to mail: [email protected] {cyber criminals’ email}
After receiving the payment, we will contact and give you decryption tools and faq how to decrypt your files.”

By analyzing the ransom message, this malware is most likely similar to most ransomware variants with the only difference that it demands significantly more money to decrypt the data (2 BTC). The malware is also poorly written, which means that there is a possibility that it is being used as a part of a RaaS scheme (Ransomware as a Service). Such schemes sell ransomware variants to absolutely anyone for a couple of hundreds of dollars. They also allow the cyber-crooks to customize the ransom note, algorithm and extension.
