Ransomware gang demands $5.3 million from New Bedford; city restores from backup instead

A ransomware
gang looking to get rich overnight went to the city of New Bedford with a demand
of $5.3 million after infecting the municipality’s systems. The criminals
refused a counter-offer that would make many hackers drool. And instead ended
up with nothing.

One July night, according to New Bedford Mayor Jon Mitchell, the attackers infected the city’s IT network with Ryuk, a prominent strain of ransomware. 158 workstations had been encrypted when IT administrators discovered the attack on the morning of July 5, Mitchell said at a press conference yesterday. They quickly disconnected the infected systems from the network, reducing the damage considerably. According to the mayor, the infected workstations represented only four percent of the city’s government infrastructure.

The hackers demanded
the exorbitant sum of $5.3 million for the decryption keys, but city officials
decided not to cave in. Instead, they made a counter-offer of $400,000, which
the city’s insurer would have covered – likely at the insurer’s recommendation,
as recovering from a ransomware attack the hard way typically ends up costing
the same, or more. However, the gang refused, and communication between city
officials and the ransomware operators became severed.

light of these considerations, I decided to make a counter-offer using
insurance proceeds in the amount of $400,000, which I determined to be
consistent with ransoms recently paid by other municipalities,” Mayor
Mitchell said. “The attacker declined to make a counter-offer, rejecting
the city’s position outright.”

IT administrators
then proceeded to recover the lost data from backups. It isn’t immediately
clear if the city had backed up all the data encrypted by Ryuk.

operators are increasingly targeting government systems and critical
infrastructures in the United States as victims often comply with the
attackers’ demands. In June, two cities in Florida paid a cumulative $1 million
ransom to the criminals who crippled their systems with ransomware. In its “how
to deal with ransomware” rulebook, the Federal Bureau of Investigation
notoriously advises ransomware victims to refuse paying ransom. However,
industry experts are sometimes on the fence — for instance when a medical
center’s patient data is held to ransom, putting actual lives at stake.
