DHAKA - A spelling mistake in an online bank transfer instruction helped prevent about $1billion heist last month involving the Bangladesh central bank and the New York Federal Reserve, banking officials said.
Unknown hackers still managed to get away with about $80million, one of the largest known bank thefts in history.
The hackers breached Bangladesh Bank's systems and stole its credentials for payment transfers, two senior officials at the bank said.
They then bombarded the Federal Reserve Bank of New York with about three dozen requests to move money from the Bangladesh Bank's account there to entities in the Philippines and Sri Lanka, the officials said.
Four requests to transfer a total of about $81m to the Philippines went through, but a fifth, for $20m, to a Sri Lankan non-profit organisation was held up because the hackers misspelled the name of the NGO, Shalika Foundation.
Hackers misspelled "foundation" in the NGO's name as "fandation", prompting a routing bank, Deutsche Bank, to seek clarification from the Bangladesh central bank, which stopped the transaction, one of the officials said.
There is no NGO under the name of Shalika Foundation in the list of registered Sri Lankan non-profits.
Reuters could not immediately find contact information for the organisation.
Deutsche Bank declined to comment.
