A cryptocurrency wallet is a collection of private keys that give its owner access to the digital assets associated with those keys. A wallet can be stored online, on your personal computer, or even on a piece of paper.
When you buy cryptocurrency, keep in mind that they don’t have intrinsic value. Instead, their value comes from the trust people have in the networks they operate on. The blockchain technology that underpins these networks ensures that transactions cannot be reverted and funds cannot be spent more than once by the same person.
Private and Public Keys
The private key is an alphanumeric string that allows you to spend funds from your wallet. The public key is the corresponding address used for receiving funds from others. There is no practical way to know someone’s private key just by knowing their public address, which means that if you purchase cryptocurrency and want to spend it, only you can do so.
While this may seem like a simple enough notion to grasp, there are still many questions surrounding it. How do my coins get stored? How do I go about using them? And most importantly — how do I keep them safe?
Cryptocurrency Transactions Can’t Be Reversed
Cryptocurrency transactions are irreversible. This means that once you send money to someone, there is no way to get it back without their consent. If you have any doubts about the recipient’s identity or whether they are trustworthy, this process should be carefully considered. In such cases, it is better to convert cryptocurrency to local fiat and use that instead.
While some people may see these unique benefits as an advantage, there’s also a downside to this lack of oversight: transactions are anonymous and there is no way to trace them back if something goes wrong in the transfer process. This can make it more difficult for people who want their funds returned after agreeing on a payment method with another party but not receiving what was promised in return.
If something goes wrong during the transfer process or either person decides they do not want to complete the transaction anymore, then neither side will have access to those funds again.
Keyloggers Are Used to Steal Cryptocurrency Wallet Passwords
Cybercriminals have stolen money from cryptocurrency wallets because they have learned someone’s password. They have done so by using a keylogger or other types of malware. A keylogger is a piece of software that records keystrokes and shares them with hackers.
This can be used to steal passwords for cryptocurrency wallets, as well as information such as 16-digit numbers when you buy crypto with a credit card. Login credentials for email and social media accounts can be targets as well. There are several ways that keyloggers can be installed on computer systems. Clicking links in phishing emails, downloading files from unsafe websites or P2P networks, and inserting malicious USBs into computers are all ways to create access points for hackers.
Computer Microphones Are Activated So That Hackers Can Listen In
In addition to the software threats mentioned earlier, your cryptocurrency could also potentially be stolen through hacking. For example, if a hacker can get into your email account and make your password change there, they’d theoretically be able to access any of your other accounts that use the same password.
People have also had their computer microphones activated without their knowledge so that hackers could listen in and hear their passwords as they were typed. Some hackers record keystrokes to gain access to logins, credit cards, or even bank accounts.
Others target computers with malware that allows them to take screenshots or access files/contacts. Hackers may also steal identities by accessing personal information stored on a computer.
Because of these threats and others like it, you need to have strong passwords, keep software up-to-date, and avoid using shared computers.
Replay Attacks
Usually, cryptocurrency transactions are sent from one wallet to another. This can be done in two different ways: publicly and privately. In a public transaction, there’s a “public key” that anyone can access and see the transactions made from that wallet. In a private transaction, only the person who owns the wallet knows about it.
But did you know hackers can use the information from both types of transactions to perform something called a “replay attack?” A replay attack is when hackers create a copy of a transaction made from an online wallet and try to send it twice by using their credentials.
Luckily, not all cryptocurrencies have this problem with replay attacks because their blockchain doesn’t allow for this type of double-spending. So, check for this feature when you’re choosing which one to buy. If there isn’t any way for someone else to get into your wallet then don’t worry about getting hacked when sending private transactions. Your information won’t get copied even if someone does manage to steal some data.
Your Funds Might Be Lost Forever
You should always have a backup of your wallet file. In some cases, you might lose the funds in your wallet forever if you don’t have a backup. If your computer’s hard drive crashes or you lose access to your files for some other reason, your backup file is the only way to get back into the wallet and reclaim ownership of everything in it.
The same is true if someone gains unauthorized access to your device and steals its contents, including any cryptocurrency stored on it. Wallet software usually protects each wallet file with a password or passphrase. This adds an extra layer of security that makes it more difficult for hackers to steal from you digitally.
However, some hackers can gain physical access to devices and still find ways around that security measure. That’s why making regular backups of all important data on a device, including cryptocurrency wallets, is so critical. If hackers do manage to steal from you, having multiple backups means that they can’t take everything at once.
Finally, keep in mind some simple rules. Have regular backups and store them somewhere secure (where they won’t be stolen along with your computer). Keep malware out of your system by using strong passwords and updated antivirus software—and never download anything suspicious! Make sure the internet connection you’re using is secure.
