Can you really not follow the trail from the mixers?

CipherTrace says they lost the trail on the twitter hackers when they threw the btc they scammed into mixers. On the other hand, the Feds arrested a kid in Florida, so my question is... how did they find him?

There are other ways to track them than the trail of their BTCs. For instance, did they apply a proper opsec hygiene? Did they brag about it, to friends online or offline?

What are the chances this is a $4.5m transfer to North Korea?

Low. The hackers are likely European, since there are telltales like European number formatting ("10.000.000$") and awkward phrases like "make a step forward" (perhaps Italian fare un passo avanti ?).

it seemed weird to me that the hacker's messages were right-justified, maybe from a country with RTL input method?

That's because you live in a country with a functioning currency.

I keep hearing that, but I am not familiar with any data that shows actual widespread use by common people* in those countries without a functional currency. Most of these countries barely have a stable internet connection or even stable electrical power, so I wouldn't surprised if these 'currencies' aren't so helpful in practice. * Note that use by corrupt politicians to launder their ill-gotten gains is not a posit…

I wonder if this is a good argument to use cloud service providers. I'm sure if someone got into your network they could probably delete everything from your corporate Google Drive/Microsoft Office accounts, but these big companies are more likely to be able to restore from backup than you are. Similarly, good managed cloud databases will have backup and restore options that are much easier than setting up immutable backup infrastructure for your company, which might encourage companies to back up more often.

We need to make laws in western countries that paying off these kinds of ransoms is illegal. It gives money to criminal elements and only encourages this. I also thought it would be possible for powerful law enforcement groups to follow the bitcoins even through exchanges. Why does this not run into the worldwide hunt for the perpetrators?

It's theoretically possible for powerful state-level adversaries to follow bitcoins through tumblers and exchanges (If they operate the former). Also, at some point, you're going to have to be paying rent, so you'll need to turn your BTC into dollars or pezos or pieces of eight, and may need to explain to your friendly tax authorities how you can by 4.5 million USD worth of BTC.

In practice, though, it's not clear what exactly are the capabilities of each branch of law enforcement.

Banning... how?

It's screencaps from one of those annoying in-browser support chat systems, where doing text-align: left for one side and text-align: right for the other is pretty common.

Let this be a lesson to those that say bitcoin and other cryptocurrency has no real value outside of speculation. This kind of attack would be almost impossible in the pre-bitcoin era. The difficulty of receiving that volume of money in that short of a period of time in a difficult to trace manner is a new thing. We are entering a new era where crime can pay in very large sums with orders of magnitude less complexity…

Bug bounties rising to their actual market price is not a negative value for society.

I think people say "no value outside of speculation, money laundering and crime".

More people can do this but I think "almost anyone" is something of an exaggeration.

>it is increasing difficult to cash out in a large way It is actually difficult to cash out?

I imagine you'd get caught on the off-ramps, since you'd most certainly be reported (by the exchange and/or your bank) to FinCEN. At that point you'd have to contend with the "the money came from bags of cash that just landed in my back yard" problem if federal agents come knocking. As for whether the federal agents will show up at all, I'm not sure. There probably aren't too many criminals who would openly admit tha…

Would fincen show up in Russia? And tumblers can hide the source easily. 4m$ is a lot to clean but it’s not impossible.
