Memory dumps of suspicious executables were uploaded to VirusTotal one day after the City of New Orleans ransomware attack. Memory dumps are a snapshot of the memory being used by an application while it is running. They can be used to extract useful strings, file names, commands, and other information that the executable interacted with or executed. The memory dumps show that a file of that name was used on an attack against the New Orleans City Hall. It is not known if this file is the one used in the attack but it does show that this file was used in Ryuk attacks.
