Two interesting attack campaigns that revolve around the abuse of Microsoft Teams and npm web portal have come to notice in the last 24 hours. In one incident that involved the use of Microsoft Teams, threat actors created fake ads related to the app to deploy Cobalt Strike backdoor. On the other hand, the attack leveraging npm web portal distributed a malicious JavaScript library called discord.dll - designed to steal sensitive files from a user’s browsers and Discord application.

The use of the Cobalt Strike tool was also observed in another attack campaign that involved the mass exploitation of vulnerable Oracle WebLogic servers. The flaw in question is related to a remote code execution bug existing in different versions of the servers.
