Binance Confirms Cyberattack Amid Reports of Record Crypto Theft; Cause Still Unknown
Confirmed attack, unconfirmed origin, and no agreed number for the loss
Binance has confirmed an attack. Why is this one drawing so much attention?
Scale and position. Binance is the largest exchange by daily trading volume, and the estimates, if they hold, would top the 2025 Bybit theft of about $1.5 billion.
Those are big ifs. Which numbers are actually solid?
Very few. Glassnode's $5.3 billion is an estimate from an advisory firm, not from Binance.
Right, and Binance hasn't confirmed the stolen value or the origin. Only the attack itself is confirmed.
What about the $1.6 billion Tether mentioned?
Ardoino said that much has been frozen in connection with a potential Binance hack. Note the word potential.
And frozen is not the same as stolen. We also don't know the total frozen across Tether and Circle.
Is Polymarket part of this?
It had its own attack hours earlier, and Hudson Rock points to DebugBear, a monitoring tool with its own incident. A link to Binance isn't established.
Correct. Timing alone proves nothing. The post-mortem is what to wait for.
Der Puls
- Binance, the largest crypto exchange by daily volume, has confirmed a cyberattack but not the method of entry or the amount taken.
- Bitcoin, Ethereum and Solana have each slid as much as 5%, rattling traders who are still waiting for facts.
- Estimates of losses range widely, with Glassnode suggesting around $5.3 billion, a figure that would eclipse the 2025 Bybit theft.
- Tether and Circle have frozen accounts to protect customers, with roughly $1.6 billion reportedly held, though neither has confirmed its own exposure.
- Binance is working with law enforcement and promises a full post-mortem, while users are urged to trust only official channels.
- A separate Polymarket breach and a DebugBear security incident may or may not connect to the larger attack, leaving investigators with unanswered questions.
When the world's most active crypto exchange admits it has been breached, the event lands less as a single crisis than as another chapter in a long human struggle to trust systems we cannot physically hold. Binance has said it is working with police and its own security teams, but it has not yet said how the intruders entered or how much they carried away. Estimates that circulate in the markets are unverified, and the markets have already responded with a sharp, nervous retreat. What remains is a question of patience: whether the promised post-mortem will reveal the shape of the wound, or whether the uncertainty itself becomes the story.
Binance, the world's largest crypto exchange by daily trading volume, has confirmed it is dealing with a cyberattack. What it has not confirmed is how the attackers got in, or how much they took. In a statement, an executive said the company is working with law enforcement and its own security teams, though she did not say whether the effort spans several countries.
The market did not wait for answers. Bitcoin, Ethereum and Solana have each dropped as much as 5% since the announcement. Binance has promised a full post-mortem once the investigation concludes and has asked users to rely only on its official channels.
The numbers now circulating come from outside the company. Tether says about $1.6 billion in crypto has been frozen in connection with a potential hack, and Tether and Circle have both frozen accounts to limit customer losses. Glassnode estimates the theft at around $5.3 billion, which would be the largest crypto theft on record and would surpass the 2025 Bybit hack. Binance has not confirmed any of these figures.
The attack arrives during a crowded stretch that security experts have nicknamed "Black October," marked by high-profile breaches, automated AI agent actions and data leaks. Hours earlier, the Polymarket platform had confirmed its own attack and paused operations, and researchers traced that incident to DebugBear, a third-party monitoring tool. Whether the two episodes are connected remains unknown.
For now, the origin, the amount stolen and the links between these incidents are all open questions. The first real answers are likely to arrive with Binance's promised post-mortem.
Binance, the world's largest crypto exchange by daily trading volume, has confirmed it is dealing with a cyberattack. What it has not confirmed is how the attackers got in, or how much they took. In a statement, Yi, the Binance executive quoted in the reporting, said the company is working with law enforcement agencies alongside its own security checks. She did not say whether that involves coordination across several countries.
The company promised a full post-mortem once the investigation is finished, and asked users to rely only on official Binance channels for updates. Markets did not wait. Bitcoin, Ethereum and Solana have each dropped as much as 5% since the attack was announced.
The figures attached to the incident vary widely, and none come from Binance. Tether CEO Paolo Ardoino said about $1.6 billion worth of crypto has been frozen in connection with a potential Binance exchange hack. Tether and Circle, two other major platforms, have both frozen accounts on their exchanges to limit potential losses for customers. Neither has said whether it is under attack itself, and the total value being safeguarded by these freezes is not known.
Glassnode, a digital asset advisory firm, puts the value of the Binance hack at around $5.3 billion. If that estimate or anything close to it holds, this would be the largest crypto theft on record. It would surpass the 2025 Bybit hack, in which hackers linked to North Korea stole about $1.5 billion. Binance itself has not confirmed the value of what was stolen.
The attack arrives in a crowded stretch. Over the past couple of weeks, high-profile cyberattacks, automated actions by AI agents, and data breaches have led security experts to nickname the period "Black October." Hindustan Times earlier reported that the internet is under attack and that few answers exist for consumers and businesses about what to do.
Hours before the Binance news, the decentralised prediction platform Polymarket confirmed it was facing a cyberattack and paused operations. Research platform Hudson Rock indicates the Polymarket incident traced back to DebugBear, a third-party website monitoring tool that was dealing with its own ongoing security incident. Whether that episode is connected to Binance has not been established.
The nature of cryptocurrency adds to the strain. It is unregulated, and its value is not anchored the way defined currencies and metals are, so large volumes of withdrawals or deposits can swing prices sharply.
For now, the questions remain open: the origin of the attack, the amount stolen, and whether Polymarket and DebugBear are linked to it. The first answers are likely to come in Binance's promised post-mortem.
