Hackers can potentially access your money through your account number, but generally, the account number alone is not enough. Here's how they might exploit it in combination with other techniques:
Social Engineering: Hackers may use your account number to craft phishing scams or impersonate legitimate institutions, tricking you or your bank into revealing sensitive details like passwords, PINs, or other personal information.
SIM Swapping: If a hacker obtains your account number, they might target your phone number to perform a SIM swap. This allows them to intercept SMS-based verification codes from your bank, enabling them to access your account.
Identity Theft: With additional personal details (e.g., name, date of birth, or address), hackers can impersonate you and convince your bank or service providers to reset security settings, gaining access to your account.
Linked Payment Services: If your account number is linked to online payment services, hackers may attempt to exploit weak security measures (such as poor passwords or outdated software) to transfer funds.
Fake Direct Debit Requests: Hackers may try to set up unauthorized direct debits or automatic payments from your account if they manage to gather enough personal information.
