Studying a number of critiques and evaluation on recent ransomware assaults, particularly essentially the most well-known one on Colonial Pipeline which paid a ransom of 75 bitcoins (about $4 million), I’m seeing plenty of dialogue about what the victims did improper and the way they will keep away from such assaults sooner or later. However nobody is asking (not to mention answering) a quite simple query: What did the hackers do improper that allowed the FBI to recuperate at the least a half of the ransom already efficiently transferred to them by Colonial Pipeline? And an much more necessary query: How did they make the error of permitting their transaction to be traced?
For anybody working with blockchain tech, it’s apparent that ransomware hackers who use bitcoin for the payoff don’t care a lot about their anonymity. Individuals coping with crypto know that bitcoin is a pseudonymous cryptocurrency, that means that it does present some primary diploma of anonymity, however scrutinization of the bitcoin blockchain unleashes plenty of details about each the sender and the recipient. And, after all, all the main points of transfers and their quantities are publicly seen to anybody. So utilizing bitcoin as a cost technique, particularly for criminality akin to ransom is extraordinarily harmful for the attackers. They are often simply traced and caught, and their cash may be seized. The chance that the Colonial Pipeline attackers didn’t know such fundamentals about crypto is close to zero. They will surely have identified there are well-developed privacy-centric cryptocurrencies tht present virtually absolute anonymity and safety to their customers.
Monero is one excellent instance; it hides all the main points of its transactions from public view, together with the sender, the recipient, and the switch quantity. And it is extremely liquid, with a market capitalization of more than $4.5 billion and a presence on most cryptocurrency exchanges. So why did the attackers not use it — or one other privacy-centric cryptocurrency? There are two attainable solutions to this query. I don’t know which one is correct.
The primary risk is that they merely didn’t care. Most are in all probability positioned within the hacker-haven international locations akin to Russia, China, North Korea, or Iran, that don’t have extradition agreements with the West. So they aren’t afraid of the FBI, not anxious about being caught, and easily didn’t assume the regulation enforcement businesses can be intelligent sufficient to discover a strategy to seize their cash. The second risk is that they deliberately used bitcoin in order that they might be traced and clues about their location can be uncovered. On this situation, the assault would have been greater than only a business transaction; it will have been a demonstrative motion.
As I mentioned, I don’t know the precise reply, however there is a vital final result of this assault, particularly if it was a business one. Attackers are studying, and for the longer term assaults, different hackers, whose pursuits are purely business, might be utilizing higher strategies that can permit them to slide away unnoticed whereas maintaining their cash (properly, our cash) protected. So it’s necessary that firms brace for affect.
Whereas ransomware sounds horrible for most individuals, the safety group is aware of how you can keep away from these assaults, so there is no such thing as a purpose firms shouldn’t be protected. A “Zero trust” architecture, with complete multi-factor authentication protection will deter hackers and stop safety breaches. Safety is just not free, however latest examples present that ignoring actuality may be rather more costly.
