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 marginally depreciated against the United States Dollar in the Nigerian Autonomous Foreign Exchange Market (NAFEM) on Thursday, December 4 amid renewed forex pressure associated with December.
At the official market yesterday, the Nigerian currency lost 0.01 per cent or 18 Kobo against the Dollar to close at N1,447.83/$1 compared with the previous day’s N1,447.65/$1.
It was not a different scenario with the local currency in the same market segment against the Pound Sterling as it further shed N15.43 to sell for N1,930.97/£1 versus Wednesday’s closing price of N1,925.08/£1 and declined against the Euro by 20 Kobo to finish at N1,688.74/€1 compared with the preceding session’s N1,688.54/€1.
Similarly, the Nigerian Naira lost N5 against the greenback in the black market to quote at N1,465/$1 compared with the previous day’s value of N1,460/$1 but closed flat against the Dollar at the GTBank FX counter at N1,453/$1.
Fluctuations in trading range is expected to continue during the festive season as traders expect the Nigerian currency to be stable, supported by intervention s by to the Central Bank of Nigeria (CBN)in the face of steady dollar demand.
Support is also expected in coming weeks as seasonal activities, particularly the stylised “Detty December” festivities, will see inflows that will give the Naira a boost after it depreciated mildly last month, according to a new report.
“As the festive Detty December season intensifies, inbound travel, tourism spending, and diaspora inflows are expected to provide moderate support for FX liquidity,” analysts at the research unit of FMDA said in its latest monthly report for November.
Traders cited by Reuters expect that the Naira will trade within a band of N1,443-N1,450 next week, buoyed by improved FX interventions by the apex bank.
Meanwhile, the crypto market was down as the US Federal Reserve’s preferred inflation gauge, core PCE, likely rose in September—moving in the wrong direction. However, volatility indices show no signs of major turbulence.
If the actual figure matches estimates, it would mark 55 straight months of inflation above the US central bank’s 2 per cent target. The sticky inflation would strengthen the hawkish policymakers, who are in favour of slower rate cuts.
Ripple (XRP) depreciated by 4.5 per cent to $2.08, Solana (SOL) went down by 3.8 per cent to $138.11, Litecoin (LTC) shrank by 3.1 per cent to $83.23, Dogecoin (DOGE) slid by 2.5 per cent to $0.1463, Cardano (ADA) declined by 2.1 per cent to $0.4368, Bitcoin (BTC) fell by 0.9 per cent to $91,975.45, Binance Coin (BNB) crumbled by 0.9 per cent to $899.41, and Ethereum (ETH) dropped by 0.7 per cent to $3,156.44, while the US Dollar Tether (USDT) and the US Dollar Coin (USDC) closed flat at $1.00 apiece.
