The city of Baltimore is under attack, but not by someone armed with guns or bombs.
Two weeks ago, cybercriminals used ransomware known as RobinHood to seize control of about 10,000 of the city's computers, saying they won't relinquish access unless Baltimore hands over about US$100,000 worth of bitcoin.
Baltimore is refusing the meet the ransom demand.
However, it also isn't equipped to crack the ransomware, meaning it's been forced to go largely offline - another disturbing example of modern government's inability to keep up with the evolving threat of cybercrime.
The attack has crippled Baltimore's government - employees can't even access email - so for now, the city is resorting to manual workarounds for operations that would typically involve computer networks.
As for when Baltimore might fully recover from the attack, no one seems to know for sure. But based on a recent statement from Mayor Bernard C. 'Jack' Young, it could take awhile.
"Our focus is getting critical services back online, and doing so in a manner that ensures we keep security as one of our top priorities throughout this process," he wrote on Friday.
"You may see partial services beginning to restore within a matter of weeks, while some of our more intricate systems may take months in the recovery process."
