Five myths about breach containment with aliases

The five myths

• It makes you anonymous
• It stops every phishing message
• It removes the need for strong authentication
• Every address should be temporary
• More addresses always mean more confusion

What is actually true

Contain the exposed relationship and replace its route without moving every account. That can reduce correlation, improve context and make one exposed relationship easier to replace. It is a control surface, not an invisibility cloak.

Why the distinction matters

Unrelated spam begins arriving at an address used for one retailer. The address can tell you which relationship is involved, but it cannot certify the sender or erase information shared elsewhere.

Good tools solve a named problem. Myths ask them to solve every problem.

Use the modest superpower

The alias identifies where the trail began, not necessarily who deliberately shared it.

• Save evidence
• Change exposed credentials
• Update the genuine account
• Watch for tailored phishing
