LeChiffre Ransomware Virus: Error: “Unable to create session object” when starting Sage 100

Brought to you by NewGen, a customer-centric ERP consulting group with over 25-years of experience

Products affected – Sage 100

Description

Signs of infection by the LeChiffre file-encrypting ransomware virus affecting the Sage 100 program and data files:

Error: “Unable to create session object” when starting Sage 100

Files in the “..\MAS90” director and sub-folders have “LeChiffre” added to the end of the file as an extension

Examples:

GL_Bank.M4T becomes GL_Bank.M4T.LeChiffre
PVX.Apserv.Log become PVX.Apserv.Log.LeChiffre
CI_Password.M4L becomes CI_Password.M4L.LeChiffre
CI_Account_Val.pvc become CI_Account_Val.pvc.LeChiffre
SY1Q01.soa becomes SY1Q01.soa.LeChiffre

Paperless Office PDF files may be affected as well.

Files _help to decode LeChiffre for [MACHINENAME] and _secret_code [MACHINENAME] may be present

Note: This ransomware virus appears to be more malicious than other reported in the past because it is infecting both Sage 100 Data and Program files (*.m4p, *.pvc, *.m4t, etc.). The name Le Chiffre is French for “The Number” or “The Cipher”.
