Yamaichi Shoji: an office PC was infected with what appears to be Emotet, its past mail history leaked, and mail posing as staff reached business partners

On September 2, mail using the company's addresses turned up inside the company and at business partners. An office PC had been infected with what appears to be Emotet, the past mail history stored on it had leaked, and mail claiming to be from staff was going to the addresses in it. [1] [2]

The mail posed as replies or forwards and carried Word or Excel attachments with random letter names, or links to outside sites. Because the mail kept changing, the company updated its description of the signs as it warned contacts. [1] [2]
