How to secure cryptocurrency access to my laptop
How hardware cryptocurrency wallets work The main idea behind a hardware cryptocurrency wallet is to store the cryptographic seed in a manner that it never leaves the device. All the cryptosigning stuff is done inside the wallet, not on a computer that it is connected to.
In addition it would be nice to have some access-protection measures — like locking the device with a PIN code. And of course it would be quite useful for a hardware wallet user to be able to verify the actual transaction on the device and to either confirm or deny it. All these considerations define the most suitable design: Usually a hardware cryptocurrency wallet is a relatively small USB-connected dongle that has a display and some buttons that are used for PIN entering and transaction confirmation.
However, the inner workings of such devices can vary. The two leading manufacturers of hardware wallets — Trezor and Ledger — represent two different approaches to the hardware design. One is Secure Element , a microcontroller designed to store highly sensitive cryptographic data. The second chip is a general purpose microcontroller that handles peripheral tasks: maintaining USB connection, controlling display and buttons, and so on.
In effect, this microcontroller acts like a middleman between the Secure Element and everything else, including the user. For example, every time the user has to confirm a transaction, they are actually going through this general purpose microcontroller, not the Secure Element chip.
Researchers inspected the Ledger Nano S firmware and found that it can be re-flashed with a compromised version if a certain value is written to a certain memory address. This memory address is blocked to make it unwritable. However, the microcontroller that is used in the device supports memory remapping, which changes the address to accessible.
Researchers exploited this feature and uploaded modified firmware into the Nano S. For demonstration purposes, this modified firmware contained a Snake game. However, this modified firmware could contain, for example, a malicious module that changes wallet addresses in all outgoing transactions.
An alternative approach to compromise a hardware wallet is to use a hardware implant. Josh Datko managed to insert into a Ledger Nano S a cheap RF-triggered implant that pushes the confirmation button upon receiving a malicious radio command. The same method probably works with any hardware wallet; the researcher chose Ledger Nano S because it is one of the smallest, and therefore the most challenging for this physical attack.
Another device by the same manufacturer, the Ledger Blue, turned out to be vulnerable to side-channel attacks. Ledger Blue is a hardware wallet with a really large display and a big battery. It has a circuit board design flaw that leaks pretty distinguishable RF signals when the user is entering a PIN code. This chip is responsible both for cryptographic data storage and processing, and for managing the USB connection, display, buttons, and so on. However, as the researchers said, Trezor did a really good job with hardening the firmware, so researchers had to go for hardware hacking, where they found success.
After that they found out that when the firmware upgrade process is started, the chip places the cryptographic seed into RAM to retain it while the flash is being overwritten. In this manner, they managed to get all memory contents. Finding the cryptographic seed in this dump turned out to be no problem; it was stored in RAM unencrypted, in the form of a mnemonic phrase meaning actual words instead of random number that was easy to spot. As long as no one has access to it, your bitcoins should be fine though somewhat depreciated.
Hardware wallets are relatively easily tampered with and can be compromised even prior to purchase. Of course, the same goes for regular laptops or smartphones. Hardware wallets, in this context, are a sure thing. Your PIN code is definitely a vital piece of information for managing your crypto.
Should you have lost it, there is still a way to prevent any loss. Your recovery phrase can be used to regain access to your crypto assets. So long as you still have your word recovery phrase, you can enter it into your device and continue managing your cryptocurrencies as if nothing ever happened. We wrote an article to show how this can be done.
This is why we continuously stress the importance of keeping your recovery phrase in a secure location. Should your Ledger hardware wallet be lost, stolen or broken, your recovery phrase will be of utmost importance. If you still have your set of 24 words, you can still regain access to your valuable crypto assets.
In the event you have lost your device and no longer have your recovery phrase, your crypto would unfortunately be considered lost. An extra note on this though: if anyone were to take your hardware wallet and they also happen to know your PIN code, they can steal all the crypto assets you manage through your Ledger device.
Please never share your PIN code with anyone. Sure enough, your word recovery phrase must be kept safe at all times. Unfortunately, things can happen to it. A spelling error when writing down your word recovery phrase is easily made, but could have catastrophic consequences.
Even more, a piece of paper can easily be misplaced or lost. Now, the loss of your word recovery phrase can indeed lead to the loss of your crypto… if you can no longer access your Ledger device. In case of a spelling error, you can simply use the Recovery Check app and try to find out which word of the BIP39 word list you might have gotten wrong. If someone else managed to get a hold of your set of 24 words, however, your crypto assets are definitely at risk.
Your crypto assets would then have become inaccessible. The sole purpose of your Ledger hardware wallet is to keep the access to your cryptocurrencies completely offline. Entering your recovery phrase into any device that can connect to the internet completely defeats the purpose of using a hardware wallet.
If you enter your 24 words — in any form — on a computer, smartphone or other device that can connect to the internet, your crypto assets are at risk. This includes taking pictures of it. Once you have a new recovery phrase, you can safely use this again. Another element is to never share your 24 words with anyone. If someone else has access to your word recovery phrase, they could take all of your crypto assets.
Crypto traders need to secure their computer against attack.

| Create my own bitcoin wallet | Paper Wallets Early crypto users would write or type their keys on paper, which they called paper wallets. It also should not deny you access to your crypto because the custodian has financial issues. Secure the first part of the ruse, the target receives a package with the modified hardware wallet. If you enter your 24 words — in any form — on a computer, smartphone or other device that can connect to the internet, your crypto assets are at risk. That's how hot wallets, or those connected to the internet, are considered to be much more risky than cold wallets. All the cryptosigning stuff is done inside the wallet, not on access computer that it is connected to. You cannot access your laptop without your private keys and an interface that accesses a blockchain. |

A private key is a character key that's used to sign crypto transactions. And the transfer address is analogous to an email address that can send or receive Bitcoin. Among other things, you also need to protect your seed phrase, a string of usually 12 or 24 words that functions as a backup to your private key, as well as any login details that grant you access to crypto exchanges or wallets.
Moreover, consider using a browser extension that can block zero-day malware downloads and phishing sites, said Porteous. There are two really obvious, common attacks. The first threat is ransomware attacks, which encrypt your PC or your cryptocurrency wallet until you pay a ransom—usually in crypto.
And phishing email volumes have spiked recently, too. In November , Black Friday triggered a fold increase in sales and discount-related phishing attacks, Check Point found. The majority of ransomware attacks rely on the victim clicking a link or opening an attachment, said Porteous. If in doubt, trust the anti-malware program. To avoid ransomware attacks completely, Lopatin recommends the use of hardware wallets.
The second type of threat is phishing attacks. Phishers cast a variety of different nets, but Lopatin said that one of the most popular targets are crypto exchanges or wallets. Recently, hardware wallet manufacturer Ledger was the victim of a hack that exposed the personal details of a million customers, leaving them vulnerable to phishing attacks designed to steal their seed phrase.
Most rug pulls are accompanied by a lot of marketing and hype to get money from investors. Then, token creators will disappear once they've collected a significant amount of valuable crypto. Bragging on Social Media No one has to know how much crypto you have. Someone can also attack and force you to transfer your crypto holdings at gunpoint. Storing Private Keys Online Cloud providers have their own servers that give you an interface to interact with your data. So, their server can be shut down, and you won't be able to get to your private keys.
When they get hacked, you get hacked as well. A single successful attack could also take down millions of records in one go, including your precious data. Pro Tip: Write down your private keys and seed phrases in a notebook, then keep that notebook inside a safe or a secure location. Talking to Strangers on Social Media Cybercriminals prey on unsuspecting traders who appear to be crypto-illiterate. Fake admins of Telegram or Discord groups will message you personally and represent themselves as one of the group's administrators.
They will request your private keys or seed phrase after establishing your trust. In certain circumstances, fraudulent administrators will invite you to use a platform so that they can harvest confidential information. Pro Tip: If someone you don't know messages you about cryptocurrency, block them right away—No-Questions-Asked! Ignoring a Multi-Layered Security Feature With too many cyber threats in the cryptoverse, financial platforms should employ many layers of security.
Layered security provides a comprehensive approach to cyber defense rather than merely waiting for assaults to strike from end to end. A multi-layered security feature considers the diversity of channels each malware could be injected into. Therefore, it considers the relevance of network and end-user-level security. In other words, always use 2-Factor Authentication and other additional layers of crypto security available on the exchange.
Crypto Security Guide and Tips Crypto Security for Your Wallet Beginners tend to retain their coins on the exchange they got them from, thus trusting the exchange to keep the coins secure, giving up control over their crypto.
This is called a "Custodial Wallet," and it is prone to cryptocurrency wallet security breaches. A Non-custodial wallet is the best place to keep your cryptocurrencies after withdrawing them from an exchange. It is possible to have a wallet installed on a mobile phone or a desktop computer. However, a hardware wallet is the most secure cryptocurrency wallet.
Usually, each cryptocurrency requires a dedicated wallet, although most wallets can handle a variety of coins. Many hackers don't go after specific individuals. Instead, they build massive networks of compromised PCs. So, your current computers and networks shouldn't have any computer viruses that could be used to track keystrokes, credentials, or download other malware.
Pro Tip: Don't use the same password for your critical accounts, such as your bank accounts, crypto trading accounts, and Wi-Fi credentials. Do a complete scan of all your machines regularly. Also, consider installing a browser plugin that blocks zero-day malware and phishing websites. Crypto Security on Exchanges Centralized exchanges are far more vulnerable to hacking and data breaches.
For hackers to gain access to users' holdings, financial information, and other potentially damaging data, they just need to get past the security measures of the exchange operator. In contrast, a decentralized exchange is hard to hijack. Hackers would have to compromise every single user. The system's peer-to-peer approach allows little or no possibility for infiltration or manipulation. On the other hand, developers can easily list shitcoins on a decentralized exchange, which makes it easier to pull off a rug pull scam.
Pro Tip: Distribute your points of failure by opening accounts on reputable crypto exchanges. By doing so, you can avoid being paralyzed if a crypto exchange goes down or gets attacked. The anonymity and decentralization of P2P transactions are the primary causes of most problems. P2P networks are vulnerable to many security risks, such as malware that changes your address, software that takes over your clipboard, and P2P scams.
While computer hygiene can easily solve software-related problems, P2P scammers can sometimes be too cunning.
