The Bitcoin fever is a real magnet for thieves who come up with many ways to steal crypto. It turns out that Bitcoin stealers target not only big companies but individual users with modest amounts in their crypto wallets. Chainalysis recently revealed that $3.8 billion of crypto assets were stolen in 2022, an increase of 15% compared to the previous year. You need a better idea of how to protect crypto these days. We will keep you aware of cyber threats lurking around the corner.
Learn more about biggest crypto hacks.
Most crypto scams follow a common pattern of theft. If you are aware of these 4 common patterns, you can better secure your Bitcoin from hackers.
Nobody can tell you the exact figures, but cryptojacking might be the most popular scheme of stealing crypto. According to the confession from Cisco, a multinational tech juggernaut, about 70% of their cloud security clients suffered from this type of malware in 2020.
How to steal crypto using this malware? The criminals focus their efforts on stealing computing power for mining crypto. Cryptojackers can stealthily use someone else’s computer or server resources over long periods of time without anyone suspecting something is amiss.
At least 5% of all Monero (XMR) had been mined this way by 2018, according to a report from Palo Alto Networks. Except for this coin, cryptojackers can mine Ethereum, Dogecoin, ZCash, Ravencoin, etc. Bitcoin stealers don’t use cryptojacking malware because it takes special equipment to mine BTC rather than personal computers.
2. Info Stealers
This type of malware allows bad actors to collect credentials (such as crypto wallet details) stored on their web browser. Most info stealers cost around $100-$300 and can be used even by amateurs.
As a rule, they use the Malware-as-a-Service business model. They have their own C2 infrastructure, a web panel, and cryptos whose purpose is encrypting the file with malware to escape the basic security layers. The data obtained using such software is usually sold to Bitcoin stealers on darknet forums or Telegram channels.
A popular info stealer is еру so-called crew are, which allows users to grab and exfiltrate information from hot wallets as they provide easier access to crypto keys for making transactions.
You can mitigate info theft in two ways:
3. Social Engineering Schemes
Bitcoin stealers can resort to various social engineering techniques to weave webs of lies, leveraging common patterns of human behavior and emotional reactions in certain life scenarios. They can send malicious links via email, pose as government agency officials, send a potential victim to fake websites, and even trick crypto owners into giving away their wallet recovery codes.
One of the most vivid examples of social engineering is the Ponzi scheme. With so many scandals and revelations associated with similar scams, it should have been long forgotten and buried, but it’s still evergreen.
A recent story: PlusToken, an Asian crypto wallet service that encouraged over 3 million people to purchase the fake company’s token using BTC or ETH.
In addition, romance scams are among the most common social engineering scams. Romance scams kick off with fraud appealing to the sexual orientation of the victim. Usually, they would promise a sexual service or file in return for the Bitcoin that the victim sends. There are reports that scammers have stolen around $1.5 million worth of BTC from Tinder and Bumble.
Reading about multiple social engineering scams can massage your brain into mush. You can’t get prepared for all of them, but you need to know how to protect crypto from fraudsters of this kind. Just a few rules to follow:
4. Exchange Hack
Centralized exchanges have a friendlier gateway to crypto and Bitcoin. As a result, many people prefer to buy, sell, or keep their Bitcoins on centralized exchanges.
However, the users need complete autonomy over their accounts with a centralized exchange. This is because they keep the private keys on behalf of their customers. Hackers target to hack exchanges to access this array of private keys. Once they can get hold of the private keys, the crypto of such users, including their Bitcoin, is gone.
In 2022, some hackers successfully breached the security of Crypto.com and stole 443 Bitcoin, which is currently worth around $11 million.
To protect Bitcoin from such an attack, we recommend not putting all your funds in a centralized exchange. You should also use hot wallets or get a cold wallet. In addition, ensure that any exchange you will use has undergone penetration testing and smart contract audit.
Keeping your crypto in cold wallets would be a good idea – they are less likely to be compromised than hot wallets. However, it might not be enough for certain types of threats.
So we recommend adhering to the following points to protect against intruders:
It is extremely difficult to hack Bitcoin as a blockchain. However, it is possible to hack individual wallets that host Bitcoin.
Thieves steal crypto through various means, such as exchange hacks, social engineering schemes, cryptojacking, and info theft.
It is hard to steal Bitcoin if the victim has weak security or is not smart enough to circumvent common social engineering schemes.
Examples of cryptocurrency that have been hacked include LUNA and SOL.
