Below are one mdb signature and twp hdb signatures for a banking malware that has been repurposed to deploy ransomware and also to load other malware. The authors infect a computer and then sell access to others. Be sure that .iso and .lnk (small L) files are included in your extensions for ClamWin to scan.

Copy mdb signatures to a new Notepad or similar text writer file and save it in the ClamWin database folder as a file named Sigfile.mdb, with a file type of “All Files”. Do not save the file as a text file. The file name should be Sigfile.mdb and nothing else.

Copy hdb signatures to a new Notepad or similar text writer file and save it in the ClamWin database folder as a file named Sigfile.hdb, with a file type of “All Files”. Do not save the file as a text file. The file name should be Sigfile.hdb and nothing else.

For multiple signatures, put each signature on a separate line in a Notepad or similar file. Put mdb and hdb signatures in separate files. You can add multiple signatures to the top of an existing mdb or hdb signature file. Copy the signatures, add one blank line to the top of the file and paste the signatures there—any additional lines needed will be added. Do not add signatures to the bottom of existing signature files or you will get a ClamWin scanning error. Delete any blank lines between signatures in a file before saving the file.

After you save a signature file in the ClamWin database folder, scan something with ClamWin to make sure it works. If you get a scan error, accept my apology, and delete the signature file from the database folder or delete only the signatures that you just posted to an existing mdb or hdb file and re-save it after first removing any blank lines in the signature file. For multiple signature files, do a scan after you save each file to help you locate a file if it causes a scan error.

After 4 weeks, the malware will probably be updated, so you can delete signatures then. The date (USA) and time (24 hr) are the last two items in each signature.

Thanks to Bleeping Computer!
