The World Of Crypto Exchange Hacks Unveiled By Traders Union Experts
A recent study by Crystal Blockchain and Cointelegraph has shed light on the alarming rise of crypto exchange hacks over the past decade. According to their findings, a staggering $15.6 billion worth of funds were stolen from 2011 to 2020, with over 50 exchanges falling victim to these cyberattacks.
As revealed in the study, experts told Forbes that weak security measures in exchanges’ hot wallets and occasional exit scams by platform owners were the primary reasons behind these breaches. The study revealed alarming vulnerabilities in cryptocurrency exchanges.
Unveiling the techniques employed by hackers
Traders Union investigates malicious actors’ attack techniques on crypto exchanges, and here are a few methods applied by the hackers:
- Misconfiguration: According to Traders Union, numerous online terminals are not configured properly and are, therefore, vulnerable to attacks like content injection and clickjacking. These headers include Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
- Vulnerabilities in exchange code: According to Coverity Scan, vulnerabilities in third-party software used by exchanges, such as payment gateways or operating systems, can be exploited for phishing or malware attacks even with relatively low error rates.
- Vulnerabilities in a wallet’s smart contract code: This can allow hackers to take control of cash, according to Traders Union, whether aiming for specific wallets or an entire network.
Social engineering and SMS authentication
TU experts highlight the potential hacking methods employed by malicious individuals. These include spear-phishing campaigns targeting employees to obtain private keys and the interception of SMS messages for authentication or access recovery, particularly for individuals involved in cryptocurrency trading or exchange administration.
Here are some potential hacking methods:
- Wiretapping: Attackers intercept SMS messages using specialized equipment, infecting the victim’s phone with malware or hacking into the service provider’s server.
- SIM card cloning: Attackers clone the victim’s SIM card to gain unauthorized access to SMS messages.
- False base station: By setting up a fake base station, attackers can intercept and decrypt SMS messages using expensive equipment.
- Hacking carrier’s web platform: Attackers compromise the user account on the carrier’s web platform to redirect messages to their phone number or email address.
- Phishing call center operators: Attackers collect personal data and phone numbers to fraudulently restore a victim’s SIM card by contacting call center operators.
Security measures implemented by crypto exchanges
Traders Union emphasizes that cryptocurrency platforms implement various security measures to counter hacking attempts. Here are some critical practices:
- Multi-factor authentication: Users must enter a one-time password, typically sent via email or phone, to authorize each transaction.
- Multi-signature: Bitcoin wallets require multiple keys held by different individuals for access, enhancing security if signatories are independent.
- Cold wallet storage: Funds are distributed between hot and cold wallets, with cold wallets holding the majority of funds and being offline, ensuring physical and multi-signature security.
- Integrated security approach: Ensuring the security of exchange code and third-party libraries, considering human factors, and securing the development environment.

The Naira opened the week on Monday, January 5, higher against the US Dollar in the Nigerian Autonomous Foreign Exchange Market (NAFEM) after gaining N1.54 or 0.11 per cent to sell for N1,429.31/$1, in contrast to the preceding session’s N1,430.85/$1.
This positive run extended was witnessed against the Pound Sterling in the official market yesterday as the Nigerian currency improved its value by N5.51 to trade at N1,920.27/£1 versus last Friday’s price of N1,925.78/£1 and appreciated against the Euro by N10.80 to close at N1,667.43/€1 compared with the previous trading day’s rate of N1,687.24/€1.
At the black market, the Naira chalked up N5 against the US Dollar during the session to sell for N1,470/$1 versus the preceding session’s N1,475/$1 and at the GTBank forex counter, it lost N3 to settle at N1,438/$1 versus the previous value of N1,435/$1.
The Naira seems to have continued from where it left of in 2025, a year that it maintained relative stability, a sharp contrast from the extreme volatility witnessed in 2024. The domestic currency exchange rate appreciated by 7.4 per cent year-on-year to close FY 2025 at N1,429/$1.
Despite pressure from the movement of the Dollar in the international market early on Monday, the Naira is shielded by a broadly stable outlook, supported by rising external reserves and sustained Foreign Portfolio Investments (FPIs).
Market analysts expect that the Central Bank of Nigeria (CBN) will maintain its strategic interventions in the FX market and implement initiatives aimed at boosting liquidity and curbing speculative activities.
As for the cryptocurrency market, Ripple (XRP) continued to trade above $2, driven by heavy institutional trading and a shrinking supply on exchanges. It’s value went up by 10.9 per cent on Monday to $2.36.
Spot XRP exchange traded funds (ETFs) in the US posted $48 million in inflows on Monday, extending a green streak for the products, which have not seen a single day of outflows since their November 13 launch.
Yesterday, Cardano (ADA) grew by 4.6 per cent to $0.4202, Solana (SOL) added 2.3 per cent to quote at $138.33, Ethereum (ETH) increased by 2.1 per cent to $3,223.22, Litecoin (LTC) expanded by 1.5 per cent to $83.45, Bitcoin (BTC) rose by 0.9 per cent to $93,323.81, Binance Coin (BNB) also appreciated by 0.9 per cent to $905.01, and Dogecoin (DOGE) soared by 0.2 per cent to $0.1505, while the US Dollar Tether (USDT) and the US Dollar Coin (USDC) remained unchanged at $1.00 each.

The crude oil market was up by about a Dollar per barrel on Monday as traders assessed the possible impact on crude flows from Venezuela, home to the world’s largest oil reserves, following the capture of President Nicolas Maduro by the United States.
Brent crude gained $1.01 or 1.66 per cent to sell at $61.76 a barrel and the US West Texas Intermediate (WTI) crude appreciated by $1 or 1.74 per cent to $58.32 per barrel.
Investors digested news of President Maduro’s capture and that the US would take control of Venezuela, which is a founding member of the Organisation of the Petroleum Exporting Countries (OPEC), whose crude exports had been under a US embargo.
Venezuelan oil output has plummeted in recent decades, curbed by mismanagement and a lack of foreign investment after the nationalisation of oil operations in the 2000s. Output averaged about 1 million barrels per day last year, equating to about 1 per cent of global production.
It was reported that the US government would meet with oil companies, Exxon Mobil, ConocoPhillips, or Chevron Corp, to discuss Venezuelan oil production future.
Market analysts noted that Venezuelan production could rise by as much as 500,000 barrels per day over the next 18 months under improved political and investment conditions, a development that could further weigh on oil prices despite the likelihood of a response from OPEC and its allies (OPEC+) if inventories rise sharply.
US President Donald Trump has been very clear that the blockade of Venezuela and the capture of its president have been driven by the desire to revive Venezuela’s oil industry and regain what he alleges were stolen assets and oil.
President Trump also raised the possibility of further US interventions, suggesting Colombia and Mexico could face military action if they did not reduce the flow of illicit drugs.
Analysts are also awaiting Iran’s reaction to President Trump’s threat to intervene in a crackdown on protests in the OPEC producer.
