Market Bitcoin hack into: $40 million stolen in the second exchange is committed to 30 days

Makes exactly 30 days, Binance suffered the greatest theft of criptomonedas of the story: $6.3 billion in 20 minutes.

Today, November 2, 2026, Bitcoin Market (the main exchange de criptomonedas Brazil) announces that it was attacked with $40 million in transfers suspicious detected in 10 blockchains different.

What coincidence? Not. What Pattern? Absolutely.


PART 1: WHAT HAPPENED (FACTS CHECKED)

The incident

According To Cyber Security News:

FACT: Bitcoin Market has detected a security incident in one of their systems and suspended immediately deposits and withdrawals as a preventive measure.

FACT: The security firm blockchain Hypernative flagged more than $40 million in transfers suspicious distributed in at least 10 blockchains different.

Critical difference with Binance

Unlike Binance (which lost $6.3 billion before detecting), Bitcoin Market:

  • Detected the incident before that most of the money to escape
  • Paralyzed the system proactively
  • Worked with firms of analysis blockchain to track funds

FACT: Bitcoin Market reacted faster than Binance, but why? Because he learned from the case Binance for 30 days.

Attack Vector (limited information)

SPECULATION CONTROLLED: Bitcoin Market has not publicly disclosed the technical details of the attack vector. However, similar patterns of Binance suggest:

  • Access to credentials of internal systems (DevOps, engineer, admin)
  • Submission of withdrawal transactions not authorized
  • Coordinated movements in multiple blockchains simultaneously

PART 2: THE CONTEXT — A WAVE OF ATTACKS

Timeline October-November 2026

  • 29-30 October: Binance — $6.3 billion
  • 2 November: Bitcoin Market — $40 million detected

What is happening?

ANALYSIS: we are Not seeing random incidents. We’re seeing:

  1. Common goal: Exchanges crypto (higher concentration of funds)
  2. Similar tactics: Access to internal systems → withdrawals coordinated → multiple blockchains
  3. Similar speed: Transfers in minutes, not hours
  4. Attribution likely: Although not confirmed publicly for the Bitcoin Market, the pattern coincides with actors sponsored by states (as the group of North Korea attributed to Binance)

SPECULATION CONTROLLED: we do Not have confirmation that the Bitcoin Market was attacked by the same group that Binance, but the modus operandi is too similar to ignore.


PART 3: WHY YOU ARE STILL VULNERABLE

Bug #1: Credentials without defense-in-depth

If the pattern is similar to Binance, it means that:

  • A laptop is committed = access to critical systems
  • Without MFA in multiple factors
  • Without separation of responsibilities
  • Without additional validation for movements of funds

Bug #2: Lack of correlation of events

Successful attacks work by exploiting the disconnect between systems:

  • System: Detects access anomalous (ignore) or generates generic alert)
  • System B: Detects transaction failed (ignore it, or mark it as a ‘manual review’)
  • System C: Go movement of funds (too late)

None of these systems talk to each other in real-time.

Bug #3: Reaction manual vs. automated

Bitcoin market had to do this manually:

  1. Receive alert of suspicious movement
  2. Investigate what happened
  3. Connect with the infrastructure team
  4. To take decision to stall
  5. Run the shutdown

How long does it take this in a crisis? In Binance were 20 minutes. In Bitcoin Market was faster because they knew what to look for, but even so, they reacted after that the money will be moved.


PART 4: THE LESSON — REAL-TIME DETECTION

Scenario: intelligent System of correlation

If Bitcoin Market would have had a system that correlate events in real-time:

Second 0-5:

  • Alert: ‘Credential internal system logging service withdrawals to the [hora] UTC’
  • Correlation: ‘This access is 500x more anomalous than the base behavior’
  • Action: automatic Suspension of this token access

Second 5-30:

  • Alert: ‘the First transaction of $10M detected towards unknown direction’
  • Correlation: ‘the Address is new, has not been used before, it is blacklisted in the analysis of blockchain’
  • Action: Freeze auto fund’s on-chain (contact with USDC/USDT issuers)

Second 30-120:

  • Correlation: ‘5 concurrent transactions in 10 blockchains different’
  • Analysis: ‘Pattern identical to the attack of Binance for 30 days’
  • Action: Scale CRITICAL INCIDENT + on-call team

Result: instead of $40 million, moved, lost maybe $1-2 million before completely contain.


PART 5: HOW TO 24CEVENT WOULD HAVE HELPED

For exchanges, the difference between losing $1 million and $40 million is to have systems that detect, correlate, and respond automatically in less than 10 seconds.

1. Detection multi-source integrated

  • Event infrastructure (access to systems)
  • Behavioral abnormalities (transactions abnormal)
  • Analysis of the blockchain in real-time (address blacklisted)
  • Logs of application (the movement of funds)

24Cevent correlacionaría all of these sources simultaneously.

2. Escalation smart

  • Abnormalities → generates alert
  • Anomaly + pattern known → scale automatically
  • Anomaly + multiple indicators → CRITICAL INCIDENT + on-call

Do not wait for a human to connect the dots.

3. Automation of response

  • Block access compromised
  • Freeze funds in chain (contact with issuers)
  • Paralyze the affected service
  • Generate reports for regulatory

All this while we investigate, not after.

4. Learning from previous incidents

24Cevent would have ‘remembered’ the attack of Binance for 30 days and you would have:

  • Searched for similar patterns
  • Scaling automatically when detected identical behavior
  • Alerted to the team: ‘This is similar to Binance ago 30 days — level critical’

CONCLUSION: THE WINDOW OF OPPORTUNITY

Bitcoin market acted quickly because he learned from Binance. But the reaction was still manual.

The next exchange to be attacked in the next 30 days you need a system that:

  1. Correlate events anomalous (do not wait for human)
  2. Automatically answer (do not wait for decisions)
  3. Scale according to previous patterns (do not wait for analysis)

Without this, even exchanges to ‘react quickly’ lost tens of millions.

The question is not ‘how you can avoid an attack?’. The question is: ‘how Much time until detected that you are going on an attack, and what it can hold at that time?’

Bitcoin market replied: 30 minutes. Binance answered: 20 minutes after losing everything.

How much is it fast enough? 10 seconds.
