When a customer is identified as a sanctioned party, the immediate required action is to freeze the customer's account and assets in accordance with sanctions regulations, preventing any transactions before notifying the relevant authorities.

During a periodic CDD review, the analyst should assess whether the account activity, including cash deposits and transfers to high-risk countries, aligns with the customer's stated transaction profile. This step determines if further escalation or reporting is necessary.

Tipping off occurs when a customer is informed that a suspicious transaction report (STR) has been filed about them, which could compromise investigations and is prohibited under AML laws.
