DATA THEFT FROM THE TREZOR HARDWARE WALLET BY MAILCHIMP

 


Last Saturday, April 2nd, 2022, news broke about the email phishing scam in which users were contacted by what they claim to be a Trezor support team and some were expected to divulge their details. After the first cases were made public, wildfire broke out and Trezor was alerted to address the matter immediately.


The data theft was checked in detail and all users who were affected were contacted directly. During the analysis, it was noticed that e-mail addresses in particular were affected. Since the Trezor hardware wallet does not store the users' private keys itself, it is technically impossible for coins to be lost. Nevertheless, the scammers tried to get some private data from the users via the e-mail addresses.


The intention was to direct users to a malicious website (trezor.us), which differed from the official one only in detail ( trezor.io ). Trezor immediately warned users about this phishing website across all platforms.


MailChimp as trigger for Trezor hardware wallet data theft

The origin of the data breach went back to the email service provider MailChimp. There, an opt-in newsletter is said to have been responsible for the data leak.


Trezor explained:


MailChimp confirms that their service was compromised by an insider targeting crypto companies. We managed to take the phishing domain offline. We're trying to determine how many email addresses are affected. Until the situation is clarified, we will not carry out any communication via newsletter. Until further notice, do not open emails that appear to be from Trezor. Please ensure you use anonymous email addresses for bitcoin-related activities.


Security guaranteed - data protection questionable

With this action, it is noticeable that the Trezor hardware wallet or the ledger are safe from hacks. Because only you have access to your private key and this theft of cryptocurrencies is only possible if you pass it on to third parties. Therefore, at Krypto Guru we continue to recommend hardware wallets so that you also have permanent access to your cryptocurrencies. 


Nevertheless, there is a big problem related to hardware wallets. Because these are ordered directly from a company, which reveals some data. In addition to an e-mail address, your private address is also stored in a specific database. The danger of data theft is obvious here and also the reason why the phishing attack came about.

From offchain to offchain: Statechains meets Lightning

  Without a doubt, the most significant off-chain Bitcoin solution is the Lightning network. But in its wake, the statechain has emerged as an intriguing replacement. There is currently a proposal to link the two offchain networks. From an ocean, for example, you can see sunbeams glistening in the water, waves rippling, and possibly a jellyfish drifting toward the light. But you only see a small portion of it. The distance from the sea's surface to its bottom is hundreds of meters. It has dozens of different fish species swimming in it, crabs and starfish crawling on the bottom, shells clinging to rocks, and sea plants climbing up. A completely new world starts where your gaze diverges. You can picture a blockchain like Bitcoin, just like the sea. What you see on the outside is only a small portion of what is actually there; the set of UTXOs (coins) and transaction history that full nodes store are just the beginning of a much larger world. It's the plan, at least. With Bitcoin...

Phishing attack on popular crypto sites tries to empty wallets

  Several major crypto sites such as Etherscan, CoinGecko, DeFi Pulse, and others report malicious pop-ups scammers use to try to trick users into connecting their MetaMask wallets. The phishing attack came from a domain displaying the Bored Ape Yacht Club (BAYC) logo. "We are investigating the root cause of this attack to fix the threat as soon as possible," CoinGecko founder Bobby Ong tweeted. The phishing attack appears to have been triggered by a malicious ad script from Coinzilla, a crypto ad network, according to CoinGecko. Etherscan also advises its users not to confirm any transactions that may appear on the website. The attackers attempted to use the hype around the “bored monkeys” non-fungible tokens (NFT) to gain access to the cryptocurrencies of unsuspecting website visitors. Although the websites affected by the scam attempt have reacted in the last few hours and deactivated the advertising pop-up, it is still recommended not to connect your MetaMask wallet to ne...

Bored Ape Yacht Club NFTs stolen through phishing on Instagram

  Bored Ape Yacht Club ( BAYC ) developers announced on Monday that hackers have hijacked the official Instagram page of the popular NFT collection and posted links to a fake airdrop. Crypto enthusiasts who connected their MetaMask wallet to the rogue website subsequently had their Ape NFTs stolen. Apparently, the attack was planned to coincide with the one-year anniversary of the BAYC collection. This increased the "perceived credibility" of the phishing link. About 100 NFTs are said to have been stolen in the phishing attack . According to CoinGecko data , the minimum price for a BAYC NFT is 139 Ether ( ETH ) or $400,726. So if reports are correct, over $40 million worth of NFTs were stolen in the attack. These numbers are only the lowest estimate, however, as they are based on the lowest price.  At the time of writing, it was still unclear how the hackers gained access to BAYC's official Instagram account. Social media users have pointed out the importance of two-fact...
