Cryptocurrency Security: Risks and Best Practices
By Mr. Abhishek Srinivasan
Cryptocurrencies gained momentum in 2009 with the onset of Bitcoin, rapidly gaining popularity as an investment option due to their unique characteristics: decentralization, digital format, and secure token-based transactions. This combination offered an unprecedented level of convenience and control for investors.
However, the world of cryptocurrency is not without its dangers. While generally secure, there are inherent threats that can leave users wary. For instance, recent research shows that 2022 noted 199 crypto thefts, and 2023 noted a sharp rise with 283 incidents recorded, resulting in millions of dollars in loss.
Therefore, understanding potential pitfalls and implementing preventative measures will equip users with the knowledge to make informed decisions and navigate cryptocurrency investment’s promising yet volatile landscape.
Cryptocurrency Risks
While cryptocurrency offers strong cryptographic security, its lack of widespread regulation makes it a prime target for hackers. Today’s crypto cyber threats are evolving rapidly, becoming more diverse and intricate. To navigate this landscape safely, users must stay informed about these ever-changing risks, some of which include:
1. Account takeover
Account takeover, also known as ATO, is a serious form of cybercrime in which threat actors illegally gain access to your online accounts by impersonating you with the primary goal of stealing sensitive information. Once in, the hackers can wreak havoc by making unauthorized transactions or conducting further crimes, leading to financial losses and other damages.
2. Cryptojacking
Cryptojacking is a cybercrime where hackers take control of a user’s computer to mine cryptocurrency without their knowledge or consent. This is often achieved by tricking users into downloading malicious software (malware) disguised as legitimate apps or visiting compromised websites. These programs, like Trojan horses, can remain hidden while silently using your computer’s processing power to mine cryptocurrency for the attacker’s benefit.
3. Fake Wallets and Exchanges
The cryptocurrency landscape isn’t just susceptible to traditional hacks; a growing threat lurks in the form of fake wallets and exchanges. These malicious tools appear legitimate, designed to deceive users into compromising their security.
For instance, fraudsters could create fake wallets and exchanges that imitate the look and feel of reputable platforms. Unsuspecting users, lured by a familiar interface or enticing offers, may sign in with their credentials. This grants the scammers access to the user’s private information, which they can then exploit for various malicious purposes.
4. Social engineering
Like other financial sectors, the cryptocurrency world isn’t immune to social engineering attacks. These attacks rely on tricking users rather than exploiting technical vulnerabilities. Attackers impersonate trusted figures, like executives from legitimate crypto wallets, to manipulate users into giving away sensitive information.
A common tactic involves phone calls or emails where the attacker poses as a crypto wallet representative. They aim to steal valuable information like one-time passwords (OTPs), login credentials, or other sensitive details granting access to crypto holdings.
Cryptocurrency Safety Tips
Cryptocurrency threats are continuously evolving, becoming more advanced and sophisticated every day. To protect yourself, it is essential to adopt security best practices. This will safeguard your investments and allow you to benefit from this lucrative opportunity without compromising your financial security. Here are some safety tips to follow when investing in cryptocurrencies:
1. Carry out your due diligence
Just like any investment, venturing into cryptocurrencies requires thorough due diligence. Users should familiarize themselves with different types of cryptocurrencies, like Bitcoin and Ethereum, and understand their functionalities, use cases, and potential risks. Learn that not all crypto wallets and exchanges are created equal. Research reputable platforms with solid security practices, positive user reviews, and regulatory compliance (where applicable).
2. Use a cold storage wallet
Due to their valuable holdings, cryptocurrency exchanges and wallets are prime targets for hackers. By utilizing cold storage, you significantly reduce the risk of losing your crypto, even if a platform is compromised. This method involves storing your crypto offline on a secure device, like a hardware wallet. Unlike online wallets and exchanges, cold storage keeps your crypto off the internet, significantly reducing the risk of online attacks.
3. Keep a backup of your cryptocurrencies
Beyond cold storage, creating a secure backup of your private keys (or seed phrase) is crucial. This ensures you can access your funds if your device is lost, damaged, or stolen. Importantly, store your backup in a separate location, ideally offline, to prevent your device and backup from being compromised in a single event.
4. Employ two-factor authentication
Cryptocurrency accounts are attractive targets for hackers, and scams like account takeovers (ATO) are unfortunately common. 2FA adds an extra layer of security, providing additional security. Even if a hacker steals your password, they’ll still be blocked without the additional code or verification step provided by 2FA.
Different types of 2FA are available, and the specific options may vary depending on the cryptocurrency exchange you use. Biometric authentication, such as fingerprint scanning or facial recognition, is considered one of the most secure forms of 2FA because it relies on unique physical characteristics that are nearly impossible for hackers to replicate.
5. Use secure passwords for your crypto wallets
Creating and maintaining strong passwords is crucial for protecting yourself online, especially against account takeovers in the crypto world. The passwords should be unique and combine lowercase and uppercase, numbers, and special characters. This complexity makes them significantly harder to crack.
While strong passwords are essential, remembering them all can be difficult. This is where password managers become useful. They securely store your unique and complex passwords, so you don’t have to remember them all. This protects your crypto wallet from various threats, including password spraying and credential stuffing.
6. Avoid using public WiFi
Public WiFi is a convenient option for travelers and remote workers, offering easy internet access. However, the convenience comes with significant security risks.
The biggest concern is the ease with which hackers can intercept traffic on public WiFi networks. These “man-in-the-middle” attacks require minimal effort and allow hackers to steal information about your online activities. This includes potentially viewing your browsing history and even financial transactions.
While intercepted information might not directly lead to a device hack, it potentially exposes your online activities, transactions and sensitive details to malicious actors which can be leveraged to personalize future attacks, such as phishing scams or malware disguised as legitimate software.
7. Build a secure network infrastructure
Public WiFi networks are a well-known security risk, but securing your home network is equally important. Many routers come with pre-set passwords that users keep for convenience, unknowingly creating an easy entry point for hackers. To build a strong foundation for home network security, here are some key steps:
- Change the default router password
- Test your firewall
- Install and update security software
- Create a strong WiFi password
- Enable network encryption
