Final answer:
The description of a computer 'worm' in the question is incorrect; a worm is a self-replicating malware, not a theft method. The correct term for stealing small amounts from many accounts is 'salami slicing' or micro theft, which is a form of computer fraud.
Step-by-step explanation:
The statement provided in the question is false. A worm is actually a type of malware that replicates itself to spread to other computers, often causing harm by consuming bandwidth or possibly carrying payloads that damage hosts. The technique described in the question, involving the systematic theft of very small amounts from a number of bank or other financial accounts, is more accurately defined as 'salami slicing' or micro theft. This is a different kind of computer fraud where small amounts of money are stolen from a large number of accounts, often going unnoticed by account holders.
Hackers do indeed have various methods to gain unauthorized access to systems and personal information. The theft of identity or personal information, or identity theft, is a crime where the perpetrator uses someone else's personal and financial information without their permission, often leading to financial loss and credit damage for the victim.
