Tactic or Technique: Out of band pivot

Attackers use out-of-band pivoting to move conversations off email and onto channels with less security oversight. They start with a simple message and then try to shift the conversation to phone, text, WhatsApp, or personal email, where monitoring and protections are weaker or nonexistent.
A message may reference an urgent issue and include a phone number, QR code, or request to continue the conversation elsewhere. Once the communication moves off email, attackers can push the scam further without being seen by security tools.
This tactic works because it breaks the visibility chain. Email security may catch a bad link or attachment, but it can’t detect what happens in a phone call or private chat. That gap gives attackers more freedom to ask for credentials, convince you to take risky actions, or escalate the attack without triggering alerts.
