A locked deposit is a savings product where money must remain on deposit for a fixed period, often called a lock-in term. In exchange for reduced liquidity, the customer usually gets a higher or more predictable return than in an instant-access account. The key operational details are the term length, early-withdrawal rules, interest rate, and any fees or limits.
In cyber security, locked deposits matter because financial products are common targets for phishing, impersonation, and account-takeover fraud. Attackers may copy bank branding, rate tables, or maturity notices to trick users into revealing credentials or moving funds to fake accounts. Defenders reduce risk by checking sender identity, verifying account changes through trusted channels, and reviewing the exact product terms in the official app or website before making transfers or withdrawals.
