For the past couple of weeks Sage 100 (MAS 90/200) users have been reporting an error that says “unable to create session object” when starting Sage 100. A recent post on the Sage Support website warns of a new system threat called the “LeChiffre Ransomware Virus.” Here are some details and what you should be aware of:
Sage reports that some Sage 100 customers may have one or more of their machines compromised by a ransomware virus called ‘LeChiffre‘. The following error message displays when starting Sage 100:
“Unable to create session object”
If you see this message, it means that the Sage 100 program files have been infected with the virus which renames the actual file, adds the extension *.LeChiffre, and encrypts the file rendering it unrecoverable.
We recommend that you contact BCS ProSoft Support or your Sage Partner immediately to remove the virus from ALL machines on your network.
After removing the virus from all machines AND your backup files, restore the entire “..\MAS90” directory from a recent backup made BEFORE LeChiffre affected the system.
Note to Paperless Office users: Paperless Office PDF files may be affected and need to be restored as well.
Note to Sage 100 users on versions older than 2014: Sage does not support Sage 100 (MAS 90/200) older than 2 versions prior to the current release—which in this case—versions that are older than 2014. However, BCS ProSoft’s Sage 100 support team supports all versions of the product.
