Kaspersky Lab security researchers reported that they have found a new spam campaign which attacks corporate mailboxes by using the Loki Bot malware.

“The malware’s key objective is to steal passwords from browsers, messaging applications, mail and FTP clients, and cryptocurrency wallets. Loki Bot dispatches all its loot to the malware owners.”
Usually, the spam messages are disguised as notifications from other companies, or as orders and offers.
The malware operators are sending out copies of Loki Bot malware to companies’ email addresses which are available on public sources or at the companies’ own websites.
