The most interesting and unknown question is how the DOJ/FBI came to be in possession of the private key.

If they carried out the attack they would have had the private key in their possession.

gigglesnort

or by "in possession of the private key" they mean "Coinbase generated the private key earlier and just gave it to the FBI"

the amateur hour doesn't stop there though

That was exactly my thought.

Especially together with 'FBI Director Compares Ransomware to 9/11' articles like https://www.foxbusiness.com/technology/fbi-chris-wray-ransom...

Thanks!

You might find it interesting to know that, irl, I never talk about anything remotely conspiratorial. I live life like a normal person, and talk like this on forums as a hedge.

A private key is not needed if the funds are on an exchange. Apparently there is a warrant to seize property on Northern California so I guess it might be Coinbase.

And yeah... if the crackers sent the funds to an exchange they were comically dumb.

Re:DOJ seizes $2.3M in cryptocurrency paid to the ransomware... by koheripbal on Monday June 07, 2021 @06:32PM (#27428128)
The warrant does not imply that the coins were on an exchange. The warrant only indicates that they needed legal authority to seize coins, wherever they are.

It seem more likely that the FBI/NSA had and gained some access to the gang's infrastructure and seized the money.

Transmitting ransom money to an exchange without any type of tumbler or atomic swapping, that it's not a realistic scenario.

Maybe they tried to use an ineffective tumbler?

Re:DOJ seizes $2.3M in cryptocurrency paid to the ransomware... by TZubiri on Monday June 07, 2021 @08:04PM (#27428966)
Why not?

Why would you assume an attacker uses all of the best cloaking tactics?

This doesn't seem like a complex attack at all: monitor common 0 day vuln feeds, attack, install off the shelf ransomware sold by 5$.

It might as well have been a script kiddie.

That’s my prediction: these guys are like bike thieves who found out the hard way that they just stole a bike belonging to the police chief and so it’s actually being investigated rather than written off. I don’t think they were remotely prepared for this level of scrutiny.
Re:DOJ seizes $2.3M in cryptocurrency paid to the ransomware... by mike00632 on Monday June 07, 2021 @10:31PM (#27430012)
My thoughts exactly. Isn't the tactic to phish multiple potential victims and then they just get email responses from the victims whose data was caught? From the attackers' perspective they could have accidentally made a big catch instead of "targeted critical national infrastructure".
Re:DOJ seizes $2.3M in cryptocurrency paid to the ransomware... by acdha on Monday June 07, 2021 @10:52PM (#27430142)
I’d bet that’s exactly what happened. These guys don’t want a big deal, they want a quick payment from the company’s insurance company and moving on.

DarkSide's announcement that they were shutting down said that their servers were compromised and taken offline. Presumably the private key was on the server and the server was hosted on a business that responds to U.S. subpoenas.
Re:DOJ seizes $2.3M in cryptocurrency paid to the ransomware... by vmception on Monday June 07, 2021 @06:57PM (#27428386)
The warrant is for a location in Northern California and they needed a warrant to get it.

Use your head man, this means they literally went to a Federal Judge and said "hey we have probable cause that this address is on Coinbase" and the Judge was like "wow that is pretty probable" and then they took the warrant to Coinbase who was like "oh damn that's legit ..... can we squirm out of dealing with this .... no ... oh wow that is our address too, okay here is the private key" and then the FBI transferred it

Re:DOJ seizes $2.3M in cryptocurrency paid to the ransomware... by dragonwriter on Monday June 07, 2021 @09:25PM (#27429597)
> The warrant is for a location in Northern California

No, its not.

Its for a particular Bitcoin address for which the FBI had the primary key. The FBI can’t legally seize coins just because it has a private key any more than it can seize physical property because it has a key to a house. It needs a warrant to use the key, which will only be issued with probable cause that the material is subject to seizure.

> Use your head man, this means they literally went to a Federal Judge and said "hey we have probable cause that this address is on Coinbase"

They literally did not; the warrant and supporting affidavit are public (with some redactions), and that is not, even remotely, what they say.

Not neccessarily.

https://www.justice.gov/opa/press-release/file/1402056/downl...

The FBI in Northern California simply needed permission to use the Private Key they already had to access the bitcoin address.

The court that has jurisdiction over these types of crimes is in Northern California.

Maybe not nowadays, but some time ago, after the possibility of tracing transactions was already well known, criminals were still a) first sending all the ransoms they collected directly from the initial ransom address to one address, linking them b) then sending them to their exchange account. No tumbling or obfuscation whatsoever.

Re:DOJ seizes $2.3M in cryptocurrency paid to the ransomware... by vesinisa on Monday June 07, 2021 @06:31PM (#27428117)
The press release specifically mentions that the cryptocurrency was seized through FBI having posession of the private key.
Re:DOJ seizes $2.3M in cryptocurrency paid to the ransomware... by sneak on Monday June 07, 2021 @07:05PM (#27428456)
As someone who has been on the receiving end of federal seizure orders for cryptocurrency private keys, they were in my case satisfied by publishing a transfer (signature) to a USG address, not actual disclosure of private key material, despite that being explicitly stated in the order.

I have heard that they have been developing an in-house technical capability and department for this since at least the time period of the Ulbrich arrest and the "first" Silk Road.
Re:DOJ seizes $2.3M in cryptocurrency paid to the ransomware... by sneak on Monday June 07, 2021 @07:11PM (#27428531)
Either that or they just approached it like a bank account and simply wanted the money and didn’t care about the cryptographic specifics whatsoever.

It's not an either/or thing though, right? IMHO, it seems plausible for the FBI to get a private key from a cooperating exchange?
Re:DOJ seizes $2.3M in cryptocurrency paid to the ransomware... by SavantIdiot on Monday June 07, 2021 @06:58PM (#27428391)
To the previous poster's point: it didn't say which private key. There can be multiple with cloud storage.
Re:DOJ seizes $2.3M in cryptocurrency paid to the ransomware... by psychlops on Tuesday June 08, 2021 @08:06AM (#27434010)
From the press release, the scare quotes could mean anything, but they likely had the rough equivalent part:

for which the FBI has the “private key,” or the rough equivalent of a password needed to access assets accessible from the specific Bitcoin address.

Re:DOJ seizes $2.3M in cryptocurrency paid to the ransomware... by ulzeraj on Monday June 07, 2021 @06:37PM (#27428167)
Did the crackers surrendered the private keys? And if so why was a warrant issued?

I don't understand why so many people are jumping to the conclusion that the FBI broke sha-256.

Theres so many other lower hanging fruit posibilities...

1: they served the server provider with a warrant they provided physical access. 2: their server infra was running vulnerable code for another service. 3. weak passwords / weak security in general 4. they cut a deal with the upstream ransomware providers and were provided with the private key used.

A very odd conclusion because that's not the crypto you need to break to steal some coins.

Re:DOJ seizes $2.3M in cryptocurrency paid to the ransomware... by Wheaties466 on Tuesday June 08, 2021 @02:22PM (#27438885)
