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 NASD Over-the-Counter (OTC) Securities Exchange returned to positive territory after it chalked up 1.18 per cent on Wednesday, June 24.
The NASD Security Index (NSI) was up during the session by 50.02 points to 4,289.36 points from the previous session’s 4,239.34 points, and the market capitalisation got a N30.03 billion boost to settle at N2.574 trillion compared with Tuesday’s closing value of N2.544 trillion.
The growth witnessed yesterday was influenced by two securities, led by Central Securities Clearing System (CSCS) Plc, which improved its value by N4.68 to N79.68 per share from N75.00 per share. Food Concepts Plc grew by 25 Kobo to sell at N2.75 per unit versus the preceding day’s N2.51 per unit.
At the close of trading activities, the value of securities bought and sold by market participants went up by 1,387.1 per cent to N82.9 million from the preceding session’s N5.6 million, and the volume of securities soared by 1,162.2 per cent to 2.7 million units from the previous 211,671 units, while the number of deals was halved by 50 per cent to 19 deals from 38 deals.

The value of the Naira further depreciated by 0.72 per cent or N9.90 against the United States Dollar to N1,380.54/$1 in the Nigerian Autonomous Foreign Exchange Market (NAFEX) on Wednesday, June 24, in contrast to Tuesday’s exchange rate of N1,370.64/$1.
Equally, the local currency weakened against the Pound Sterling in the same official market yesterday by N4.88 to close at N1,815.63/£1 versus the previous session’s N1,810.75/£1, and lost N2.61 on the Euro to sell at N1,563.63/€1 compared with the preceding day’s N1,561.02/€1.
However, at the GTBank forex counter, the domestic currency maintained stability against the US Dollar during the session at N1,380/$1, and at the parallel market, it closed flat at N1,395/$1.
Rising FX payments and a strong US Dollar have generally put significant pressure on emerging-market currencies, like the Naira.
According to the data from the Central Bank of Nigeria (CBN), NFEM interbank FX turnover was relatively steady at $125.588 million across 126 deals, from $125.314 million the previous day.
Interbank FX activity among financial institutions has fluctuated amid a sharp slowdown in forex market interventions by the apex bank, with more than six weeks of no support for the local currency.
Meanwhile, Nigeria’s foreign reserves increased further to $51.142 billion, while global oil prices entered the lower $70s.
Meanwhile, in the cryptocurrency market, nearly $1 billion worth of futures positions were liquidated across crypto majors to tokenised versions of stocks such as Micron Technology Inc (MU) and Sandisk (SNDK).
The dip triggered roughly $430 million in long liquidations on Bitcoin-tracked futures, or bets on higher prices that were automatically closed as the price fell.
Thursday’s PCE inflation print, the Fed’s preferred price gauge, is the next data point that could move the market in either direction, with Dogecoin (DOGE) down by 2.4 per cent to $0.0771.
Further, Bitcoin (BTC) fell by 1.9 per cent to $61,584.02, Ethereum (ETH) shed 1.6 per cent to trade at $1,645.50, Ripple (XRP) depreciated by 1.6 per cent to $1.08, Binance Coin (BNB) slumped by 1.5 per cent to $570.95, Cardano (ADA) crashed by 1.1 per cent to $0.1495, and Solana (SOL) slipped by 1.0 per cent to $69.19.
But TRON (TRX) gained 0.1 per cent to finish at $0.3288, while the US Dollar Tether (USDT) and the US Dollar Coin (USDC) remained unchanged at $1.00 each.

The price of Brent crude futures, the global oil benchmark, declined by $3.34 or 4.3 per cent on Wednesday to settle at $73.74 per barrel, its lowest level before the start of the Iran war on February 28, 2026.
Also, the US West Texas Intermediate (WTI) crude futures lost $2.87 or 3.9 per cent during the session to sell for $70.34 a barrel.
The development came as supply concerns eased with more stranded oil tankers exiting the Strait of Hormuz, which had been blocked since late February.
Market analysts noted that crude oil flows through the Strait of Hormuz are similar to what they were before the start of the Iran war, as tankers exit the key waterway with the help of military escorts. Around 20 million barrels of crude oil have exited the Strait of Hormuz in the last 24 hours.
Before the war began in late February, roughly 125 ships passed through the chokepoint each day, but current traffic remains a fraction of that.
Reuters reported that three stranded tankers carrying 5 million barrels of crude oil exited the strait on Wednesday, with two heading to Asia, shipping data showed, as the interim deal between Iran and the US began to unlock more supply stuck in the Gulf.
As Middle Eastern producers scramble to move crude that has spent months stranded in the Persian Gulf, tanker rates have exploded higher. The cost of hiring a tanker in the Gulf has nearly doubled in just a week, jumping from around $106,000 per day to more than $190,000 per day. For some very large crude carriers (VLCCs) hauling cargoes through Hormuz, daily earnings have surged to nearly $470,000.
The US also authorised Iranian oil sales this week, easing decades-old sanctions as it pushes toward a final peace deal with Iran in return for commitments on nuclear inspections and free transit through the Strait of Hormuz.
Oman said it would keep the strait open to shipping without imposing tolls and had designated two temporary routes north and south of the existing shipping lane to facilitate the safe passage of vessels leaving the region.
Crude inventories in the US remained tight on strong refining demand and amid a release of oil from the government’s emergency stash. The Energy Information Administration (EIA) said crude stocks, including commercial and those in the Strategic Petroleum Reserve, fell by 15.1 million barrels to 743.3 million barrels in the week ended June 19, which was the lowest level since 1984.
