Binance Hack Exposes Major Security Flaws: CryptoNakamao Loses $1 Million

  • The recent cybersecurity breach involving Binance has sent ripples through the cryptocurrency community.
  • This incident underscores potential security gaps even in leading exchanges.
  • Prominent Chinese trader, CryptoNakamao, lost $1 million to hackers using a malicious browser extension.

This article unpacks the Binance hack, highlighting the modus operandi of the attackers, scrutinizing the exchange’s security measures, and providing crucial tips for users to enhance their security.

The Mechanics Behind the Hacking Incident

The breach came to light when CryptoNakamao detected irregular trading patterns on his Binance account. In an attempt to understand the anomalous activities, he found that unauthorized trades were executed while he was merely checking Bitcoin prices using the Binance app. Despite his swift request for Binance’s intervention, hackers had already transferred his funds out. The Aggr extension, masquerading as a trading data tool, was actually capturing critical cookie data. This stolen data was then utilized to hijack active sessions and bypass common security measures such as passwords and two-factor authentication (2FA).

Exploit of Security Gaps

By leveraging the captured cookie data, hackers were able to orchestrate complex trades that included purchasing high-liquidity tokens and trading them against low-liquidity pairs. This strategy allowed them to manipulate market prices and execute leveraged trades stealthily. The traditional safeguards in place, including 2FA, were rendered ineffective in the face of session hijacking.

Raising Questions on Binance’s Security

The hackers’ ability to execute trades despite 2FA restrictions has raised concerns about Binance’s security infrastructure. They manipulated large volumes of Tether (USDT) and strategically placed limit sell orders between Bitcoin (BTC) and USD Coin (USDC). These trades created abnormal price fluctuations that the hackers exploited for their own gain through high-leverage positions.

CryptoNakamao has vocally criticized Binance for what he perceives as their failure to avert such a breach. He emphasized that Binance overlooked warning signs of irregular trading activities and was sluggish in their response to his alerts. Additionally, he accused Binance of being aware of the malicious nature of the Aggr extension but failing to provide adequate warnings or preventative measures to users.

Lessons and Precautions for Crypto Users

Learning from this breach, here are several essential security tips:

  • Avoid downloading and using unverified browser extensions.
  • Regularly check your account for any suspicious transactions.
  • Consider using hardware-based 2FA for an added layer of security.
  • Report any questionable activities to your cryptocurrency exchange immediately.
  • Stay updated on any security threats and advancements shared by your exchange platform.

Users’ Trust Shaken

CryptoNakamao expressed his profound disappointment with Binance’s handling of the incident and the potential risks associated with the Aggr extension. He condemned the inadequacy of Binance’s internal investigations and criticized the exchange for not taking stronger actions to prevent ongoing threats. He also highlighted Binance’s failure to freeze the accounts involved in fraudulent activities, exacerbating the situation for affected users.


This breach at Binance serves as a stark reminder of the continually evolving threats in the cryptocurrency space. It highlights the need for enhanced security measures, not just from exchanges, but also from users. By practicing caution and staying informed, traders can better protect themselves against such malicious attacks in the future.
