„Chain Phishing“ on Office 365 accounts

What is Chain Phishing?

In Chain Phishing, attackers first take over a compromised email account to send seemingly legitimate phishing emails to existing contacts. These messages often include deceptively real responses to previous conversations or seemingly authentic attachments and links. This lowers the recipients’ suspicion, as the emails appear to come from a trusted source.

Chain Phishing poses a serious threat to Office 365 users, as attackers exploit trust through already compromised accounts. However, with the right security measures, the risk can be significantly minimized. Most importantly, a professional backup solution can prevent data loss in critical situations and ensure business continuity.

Stay vigilant – and don’t blindly click on emails that seem familiar!
