Inactive Account Monitoring
Description
This test identifies user accounts that have an extended period of inactivity followed by high-value transactions, which could indicate irregular or suspicious behavior. By analyzing transaction patterns and time gaps between transactions, the function flags accounts that exceed a specified inactivity period and transaction value threshold.
Use Cases
-
Fraud Detection: Identify inactive accounts that suddenly execute high-value transactions, which may signal unauthorized access or fraudulent activity.
-
Account Security: Monitor reactivated accounts for irregular behavior, such as large transactions after extended inactivity, to protect users and prevent potential breaches.
-
Regulatory Compliance: Flag accounts exhibiting suspicious activity patterns for further investigation to ensure adherence to anti-money laundering (AML) and other financial regulations.

Methodology
-
Identify Inactive Accounts by User and Symbol Monitor each user's activity for each symbol to detect periods of inactivity exceeding a specified threshold.
-
Aggregate Transactions by User and Symbol Consolidate transaction amounts for each user and symbol involved, to evaluate activity patterns and financial significance.
-
Apply Threshold Criteria Flag user-symbol combinations where transaction amounts surpass a predefined dollar threshold after an extended period of inactivity.
-
Generate Alerts by User and Asset Create alerts highlighting users where inactivity and significant financial activity criteria are met.
