Last Updated: Oct 25, 2017 11:15AM UTC
A new ransomware attack began 24.10.2017 and hitting mostly Eastern European countries.
Please see the below instructions for detecting the ransomware on your windows machines.

1. Detecting ransomware files

Please see the ransomware files and hashes
install_flash_player.exe: 630325cac09ac3fab908f903e3b00d0dadd5fdaa0875ed8496fcbb97a558d0da
infpub.dat: 579fd8a0385482fb4c789561a30b09f25671e86422f40ef5cca2036b28f99648
cscc.dat (dcrypt.sys): 0b2f863f4119dc88a22cc97c0a136c88a0127cb026751303b045f7322a8972f6 
dispci.exe: 8ebc97e05c8e1073bda2efb6f4d00ad7e789260afa2c276f0c72740b838a0a93

You can download the hashes file from the following URL:


In order to detect the malicious files you should load the hashes file to our Cyber module.

Open PEM, then Management

Go to File->New->Cyber Configuration->Default 
Name the new configuration according to your desired naming convention.

Choose the hosts that you wish to inspect

Choose "Notify on hash from file" . Click on browse and choose the file that contains the hashes.

2. Detecting ransomware registry keys

Additional to the hash match, we can also detect the ransomware registry keys. In order to do that we need to prepare some user defined keys.

Those are the malware registry entries:
HKLM\SYSTEM\CurrentControlSet\services\cscc\Type	1
HKLM\SYSTEM\CurrentControlSet\services\cscc\Start	0
HKLM\SYSTEM\CurrentControlSet\services\cscc\ErrorControl	3
HKLM\SYSTEM\CurrentControlSet\services\cscc\ImagePath	cscc.dat
HKLM\SYSTEM\CurrentControlSet\services\cscc\DisplayName	Windows Client Side Caching DDriver
HKLM\SYSTEM\CurrentControlSet\services\cscc\Group	Filter
HKLM\SYSTEM\CurrentControlSet\services\cscc\DependOnService	FltMgr
HKLM\SYSTEM\CurrentControlSet\services\cscc\WOW64	1
This is how we will add those objects:

Go to Tools->User Defined->Objects Editor

Go to "Registry"

Create a record for each of the malware registry entries

Add the user defined entries to your Cyber configuration

After you run the scan, please inspect Compliance console in order to detect affected machines
