Bangladesh’s central bank was vulnerable to hackers because it did not have a firewall and used second-hand, $10 switches to network computers connected to the SWIFT global payment network, an investigator into one of the world’s biggest cyber heists said. The shortcomings made it easier for hackers to break into the Bangladesh Bank system earlier this year and attempt to siphon off nearly $1 billion using the bank’s SWIFT credentials, said Mohammad Shah Alam, head of the Forensic Training Institute of the Bangladesh police’s criminal investigation department.
“It could be difficult to hack if there was a firewall,” Alam said in an interview. The lack of sophisticated switches, which can cost several hundred dollars or more, also means it is difficult for investigators to figure out what the hackers did and where they might have been based, he added. Experts in bank security said that the findings described by Alam were disturbing.
“You are talking about an organization that has access to billions of dollars and they are not taking even the most basic security precautions,” said Jeff Wichman, a consultant with cyber firm Optiv.
Tom Kellermann, a former member of the World Bank security team, said that the security shortcomings described by Alam were “egregious,” and that he believed there were “a handful” of central banks in developing countries that were equally insecure.
