Hermes Ransomware

Once infiltrated, Hermes encrypts files using RSA-2048 cryptography. This malware does not append extensions to the encrypted files. Following successful encryption, Hermes creates an HTML file containing a ransom-demand message (“DECRYPT_INFORMATION.html”), placing in each folder containing encrypted files. It also provides a UNIQUE_ID_DO_NOT_REMOVE file that victims are encouraged to attach to email messages when communicating with the cyber criminals responsible for this malware. When Hermes is executed, it will also use a User Account Control, or UAC, bypass called Eleven, or Elevation by environment variable expansion, to delete a victim’s Shadow Volume Copies and backup files.


Hermes uses a UAC bypass to execute a batch file called shade.bat. This batch file, shown below, will not only delete the computer’s shadow volumes, but will also delete backup images that may be present on the computer. It does this to prevent a victim from restoring encrypted files from a backup.


The backup images that are deleted are ones that match the following filenames:

*.VHD, *.bac, *.bak, *.wbcat, *.bkf, Backup*.*, backup*.*, *.set, *.win, *.dsk

When the Hermes Ransomware is executed, it will copy itself to C:\Users\Public\Reload.exe and execute itself. It will then launch a batch file called system_.bat, which is used to delete the original installer as shown below.

Cyber Splitter VBS Ransomware

The ‘Cyber Splitter Vbs’ Ransomware is a ransomware Trojan that is being used to coerce PC users to spend large amounts of money by taking their files hostage. The ‘Cyber Splitter Vbs’ Ransomware uses an approach that is similar to what we’ve seen with numerous other ransomware threats that use a similar attack strategy.

Essentially, the ‘Cyber Splitter Vbs’ Ransomware will encrypt the victim’s files, making them unusable, and then demand that the victim pays large amounts of money to recover access to the encrypted files. PC security analysts are against paying the ‘Cyber Splitter Vbs’ Ransomware’s ransom.

The most plausible explanation is that CyberSplitter 2.0 was sent to your inbox. As we mentioned, ransomware doesn’t rely on your active cooperation. It uses your distraction instead. For instance, hackers often attach the virus to some corrupted, fake email. All you have to do is open it. Voila. You end up downloading a nasty infection on your own computer. Keep in mind those emails appear to be perfectly harmless. They might be disguised as job applications or emails from a shipping company. The goal is to trick you into clicking them open. To prevent infiltration, delete emails/messages from unknown senders.

Prevention is indeed the easier option. Stay away from illegitimate torrents, websites and software bundles. We would also recommend that you avoid third-party pop-ups. Ransomware might get spread online via exploit kits as well.


The only way to protect yourself is keep an updated good total security with anti virus on your PC which can take back upo every day and let you restore if you are infected such Max Total Security

CryptoShield 1.0 Ransomware

A new CryptoMix, or CrypMix, variant called CryptoShield 1.0 Ransomware has been discovered. The infected files may be sent out via a variety of e-mail templates which may be spammed to the victim, claiming they are containing an invoice or other important document that has to be opened. Usually, most inexperienced users tend to open the attachments.

After the malicious attachment is opened, the virus gets right down to business. It may create multiple malicious files, also known as modules and each of those files is responsible for different activities. The files may be dropped under different names in the following Windows folders: Appdata, temp, Roaming, user profile, common and system 32. File names could be notepad.exe, setup.exe, patch.exe, update.exe, software-update.exe, svchost.exe etc.

After dropping the files, the CryptoShield 1.0 virus may create registry entries regval and regdata in these key locations:

HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER \Software\Microsoft\Windows\CurrentVersion\Run or RunOnce

When CryptoShield starts encrypting files using AES-256 encryption, encrypt the filename using ROT-13, and then append the .CRYPTOSHIELD extension to the encrypted file. For example, a file called test.jpg would be encrypted and renamed as grfg.wct.CRYPTOSHIELD. You can decrypt the filenames by using any ROT-13 encryptor, such as

In each folder that CryptoShield encrypts a file, it will also create ransom notes named # RESTORING FILES #.HTML and # RESTORING FILES #.TXT.

During this process, the ransomware will issue the following commands to disable the Windows startup recovery and to clear the Windows Shadow Volume Copies as shown below.

cmd.exe /C bcdedit /set {default} recoveryenabled No
cmd.exe /C bcdedit /set {default} bootstatuspolicy ignoreallfailures
C:\Windows\System32\cmd.exe” /C vssadmin.exe Delete Shadows /All /Quiet
“C:\Windows\System32\cmd.exe” /C net stop vss

CryptoShield will then display a fake alert stating that there was an application error in Explorer.exe. Though, you can see spelling mistakes such as “momory” and an odd request that you should click on the Yes button in the next Window “for restore work explorer.exe”. Once you press OK on the above prompt, you will be presented with a User Account Control prompt, which asks if you wish to allow the command “C:\Windows\SysWOW64\wbem\WMIC.exe” process call create “C:\Users\User\SmartScreen.exe” to execute. This explains why the previous alert was being shown; to convince a victim that they should click on the Yes button in the below UAC prompt.

“Turla” Group Uses New JavaScript Malware

Turla, also known as Snake / Uroburos / Venomous Bear and KRYPTON is a Russian-speaking APT group that has been active since at least 2007. Its activity can be traced to many high-profile incidents, including the 2008 attack against the US Central Command, more recently, the attack against RUAG, a Swiss military contractor. The Turla group has been known as an agile, very dynamic and innovative APT, leveraging many different families of malware, satellite-based command and control servers and malware for non-Windows OSes.


The document above shows an official letter from the Qatar Embassy in Cyprus to the Ministry of Foreign Affairs (MoFA) in Cyprus. Based on the name of the document (National Day Reception (Dina Mersine Bosio Ambassador’s Secretary).doc, it is presumed it may have been sent from the Qatar Ambassador’s secretary to the MoFA, possibly indicating Turla already had control of at least one system within Qatar’s diplomatic network.

The document contains a malicious macro, very similar to previous macros used by Turla in the past to deliver Wipbot, Skipper, and ICEDCOFFEE. However, the macro did contain a few modifications to it, mainly the XOR routine used to decode the initial JavaScript and the use of a “marker” string to find the embedded payload in the document.

This JS will begin by copying itself to the appropriate folder location based on the version of Windows running:



c:\Documents and Settings\\Application Data\Microsoft\Windows\mailform.js

Next, it will write to the following registry key:

Key: HKEY_CURRENT_USER\software\microsoft\windows\currentversion\run\mailform
Value: wscript.exe /b “ NPEfpRZ4aqnh1YuGwQd0”

After establishing its persistence, it will then execute a series of commands on the victim system using “cmd.exe /c” and store them to a file named “~dat.tmp”, in the same folder where “mailform.js” is located.

Network Communications

With the victim info stored in encrypted form in memory, the JavaScript then will perform the necessary callback(s) to the C2 servers which are hard coded in the payload. The addresses seen in this payload were as follows:


It should be noted that the above domains appear to have been compromised by the actor based on the locations of the PHP scripts.

HummingBad Returns-Android Malware

HummingBad, an Android malware estimated to have touched over 85 million devices worldwide, was recently found in 46 new applications, 20 of which had even made their way into the official Play Store, passing Google’s security checks. ‘HummingBad’

Android malware briefly returns as approved ‘Whale Camera’ Play Store app. HummingBad, the malware that surfaced in February 2016 and earned its creators up to $300,000 per month in ad fraud revenue.
In terms of Android malware, HummingBad is the biggest player active today, accounting for 72% of all mobile infections.

HummingWhale works by showing unwanted ads to its victims, but when users move in to close the ad, the malware opens a virtual machine and installs the advertised app inside it. This way HummingBad authors earn revenue in pay-per-install affiliate programs and install as many apps on infected devices without polluting the device’s application list.

Furthermore, HummingWhale gained another feature, which was the ability to post reviews and ratings on the Google Play Store on behalf of infected users, a tactic used to earn an extra revenue or give a boost to other malicious apps.
