L.A. Hospital Pays Off Ransomware Thieves To Reclaim Its Network (google.com)
Los Angeles' Presbyterian Medical Center, the target of a successful ransomware attack (successful from the thieves' point of view, that is) has buckled under: to regain control of its network, the hospital has paid a 40-bitcoin ransom (about $17,000) to the gang responsible. That, at least, is a far cry from the much higher ransom widely reported to have been initially demanded: 9,000 bitcoin. (That would have meant a payment of $3.6-3.9 million.)
They fed the trolls.
Table-ized A.I.
>> the hospital has paid a 40-bitcoin ransom (about $17,000)
That's about 340 tablets of hospital aspirin or 680 hospital bandaids for those counting at home.
And, can the FBI monitor the blockchain to get IP addresses where these coins were accessed from when the hospital handed them over?
By an absolute mile. At $17,000 you would just pay it straight away. They would have lost far more as a result of the systems being offline, and assuming the ransomware had got itself all through they systems it would have been orders of magnitude more to clean the system if it was even possible.
I'm sure that they are going to take the $3.6 million that they didn't have to pay during this episode and devote that to upgrading and securing their systems to prevent the possibility of future attacks like this. That would be the smart thing to do.
Right?

Good god, doesn't anyone keep backups anymore?
Of course, this does assume that the ransomers won't come back and ask for more money next week.
I don't care if it's 90,000 hectares. That lake was not my doing.
It's a short-sighted solution though. Their systems are still vulnerable, probably even still infected. And they validated the business model of the attackers, so more attacks will be coming.
Also, while the CEO insists that hospital records were not compromised, I'm reading that as "the attackers weren't interested in hospital records", not "the hospital records were safe".
Or that the theives didn't already download a ton of patient data off their machines which since they accepted such low amount from what they wanted sounds like they got enough info to make a ton of $ off identity theft.
Short sighted from an industry view, probably not from the hospitals view. You would hope they have air gapped their network from the internet at this stage while they reappraise their security and plug holes. From my understanding the ransomware attackers don't normally attack the same target twice as you are less likely to pay up if you think it will happen again. So this should protect them from the current infection.
It also wouldn't surprise me if patient records were untouched. Those are probably behind higher levels of security than the rest of the network. What I suspect happened is they lost a way of accessing them because all their other systems went down.
... is for someone to figure out an efficient way of tracing the full transaction history of any given "coin." Yes, I know that "in theory" it's do-able but it's just plain not feasible right now.
Yes, I know BC "coins" as such don't have a history, but transactions do. If a coin is the "output" of a transaction then its "parent coins" are all the coins that went into the transaction, in proportion to each other. Yes, you can "launder money" but all that does is "spread the dirt around" resulting in "slightly dirty" BC that are considered only as fractionally valuable as their "clean" fraction.
For example, if a ransomware victim, in cooperation with the police, pays 40BC to crooks, the crooks will of course launder the money immediately, probably several times over. As soon as the keys are recovered and there is no more danger of the crooks "getting revenge," the police issue a notice that all BC whose "transaction history" included this transaction are "tainted by the dirty transaction."
At this point, reputable companies who trust that particular police authority will only accept "tainted money" based on the "clean" portion of its value. Those who happen to be stuck with the "dirty money" are pretty much out of luck, in much the same way that I am out of luck if a store clerk accepts a very good counterfeit $5 bill from a crook then later innocently hands it to me in change later that day.
Yes, this setup has many flaws, but it's better than the status quo. Some obvious flaws include:
* it's currently not feasible
* there are many police authorities, and people trust them to different degrees, so the BC in your wallet may have a different value depending on who you want to do business with.
* Whoever has coins "descended" from tainted coins at the time they are announced as tainted will be stuck with the loss
* There is no built-in appeal for a police authority declaring a particular transaction "illegal" and declaring the coins received in that transaction "tainted". The only deterrent is that if a given police authority gets too sloppy or too abusive, fewer and fewer people will honor its declarations.
* There are no doubt other flaws, this is just the ones that came to mind immediately.
Of course, the real solution to ransomware is backups, backups, backups, but we all know that's not going to happen any time soon. Sigh.
