Cracking a $2 million crypto wallet
Subscriber Account active since. The Department of Justice announced Monday that it had recovered a majority of the ransom paid by Colonial Pipeline to hackers who shut down its operations last month and caused massive fuel shortages and price hikes.
Despite cybercriminals' increasingly sophisticated use of technology to commit crimes, the DOJ said it used a time-tested approach to recover Colonial's ransom payment. On May 8, with its operations knocked offline and amid an emerging gas crisis , Colonial opted to pay the ransom much to the chagrin of government crimefighters who were simultaneously trying to shut down the hack. The FBI agent then used a blockchain explorer — software that lets users search a blockchain, like bitcoin, to determine the amount and destination of transactions — to figure out that DarkSide had tried to launder the money through various bitcoin addresses similar to bank accounts , according to the affidavit.
Eventually, through the blockchain explorer, the FBI agent was able to track Fortunately for the FBI, according to the agent's affidavit, the agency had the private key effectively the password for that address. Bitcoin addresses rely on a two-key encryption system to keep transactions secure: one public and one private.
The public key is shared openly so anybody can send money to that address. But once a sender has encrypted a payment with the recipient's public key, only the recipient's private key can decrypt and gain access to that money. That's why private keys are meant to be closely held secrets, stored in a secure place.
In DarkSide's case, the FBI managed to gain access to its private key, and after getting a seizure warrant from a federal court, the agency used the key to access DarkSide's address and swipe The FBI didn't say how it had managed to obtain the key but said it sent a warning to other would-be ransomware hackers.

The FBI likely exploited sloppy password storage to seize Colonial Pipeline bitcoin ransom
In the modern financial sector, interest in providing financial services that employ blockchain technology has increased. Blockchain technology is efficient and can operate without a trusted party to store all transaction information; additionally, it provides transparency and prevents the tampering of transaction information. However, new security threats can occur because blockchain technology shares all the transaction information. Furthermore, studies have reported that the private keys of users who use the same signature value two or more times can be recovered. Because private keys of blockchain identify users, private key leaks can result in attackers stealing the ownership rights to users' property.

Cryptocurrency's short history is littered with massive losses, where the private keys controlling millions have been stolen from exchange wallets, pilfered by scam artists, and embezzled by trusted custodians. Even those individuals who have stayed true to the spirit of Bitcoin and kept their own private keys have still suffered, with dodgy wallets, silly mistakes, and even a series of 'horrible boating accidents' all leading people to lose their cryptocurrency. To celebrate ProofofKeys , here are 7 different ways that private keys have been compromised and a few tips to help you take control of them without becoming another victim. In an effort to avoid the problems of third party custody, some cryptocurrency users take control of their own private keys. But, losing this secret string of code is easier than you might think. Last year, a digital forensics firm estimated that four million bitcoins are gone forever—with many private keys being lost in the early days before the value became evident. Some were accidentally shared and misplaced, and some—if commentators on crypto Twitter are to be believed—were lost in horrible boating accidents. British IT guy James Howells was an early adopter of Bitcoin who ended up watching others get rich without him.
New hack can steal crypto private key from air-gapped wallet
A new security threat has come to light, that targets a non-networked wallet…. A cybersecurity researcher from Ben-Gurion University of the Negev in Israel has demonstrated a new hack that can clean out a bitcoin wallet from an air-gapped computer. In a YouTube video explaining the hack, Dr Mordechai Guri shows how it is possible to leak a Bitcoin private key despite the fact that the computer hosting the wallet is not networked, uses no Bluetooth nor WiFi and is not connected to the internet.

RELATED VIDEO: Could Someone Guess Your Bitcoin Private Key?Now he has revealed how he did it. Starting in May, he periodically published hints to a word seed phrase for a wallet address that contained one Bitcoin. Whoever picked up all the clues could use the phrase to unlock the Bitcoin wallet and take the Bitcoin inside. I just published an article on how I checked over 1 trillion mnemonics in 30 hours to win alistairmilne 's 1 Bitcoin giveaway. I hope to pay-it-forward with a contest of my own that can't be won by software, details to come soon! However, Milne planned to post the last three or four words in one go.
Can Bitcoin Be Hacked?
There seems to be a heated debate in the crypto world between cold and hot wallets: cold wallets are thought to be more secure but require processing any transaction manually, while hot wallets enable high-frequency automatic transaction but are less secure. The main argument for using cold storage wallets is that they generate private keys on their own. This random string is absolutely mandatory in validating the signed transaction: Without this valid signature, the miner will simply disregard the transaction and avoid from inserting it into the blockchain. But the moment you want to buy, sell or move around Bitcoins, Ethereum or any other digital currency — you need to go online and connect your cold wallet to the internet. Because a skilled hacker knows how to creatively find attack vectors on virtually any machine connected to the internet. Once hackers set their sights on a PC with a cold wallet plugged into it — they will find a way to hack it. Since any transaction to the blockchain is irreversible, once hackers take over your local environment, they can use your private key to create a transaction and drain your account from all its digital assets in minutes.
Since then, they owners of these coins had lost the private key, or simply thrown away the drive or computer the coins were on. About 20 years ago, [Mike] was working as a cryptography expert and developed a number of interesting algorithms for breaking various forms of encryption, one of which involved. A Bitcoin owner stumbled across the paper that [Mike] wrote and realized that it could be a method for recovering his lost key from While this might not be financially feasible for you if you have a USB stick with a single coin on it you mined as a curiosity in , the cryptography that is discussed in the blog entry is the real story here.
