A message from Binance's Co-CEO, @_RichardTeng.
Investigation update: Our initial investigation suggested that the security incident may have involved a compromised laptop, however our subsequent investigation has uncovered additional points of breach.
This was a complex attack, and we are doing all we can in coordination with law enforcement to resolve it. We are still gathering the facts, and will share more directly as we have them.
Binance will cover all losses from the SAFU fund and the company’s funds. User funds are safe.
We are still on track towards the expected timeline to resume the withdrawal service in 45 hours. Deposits remain unaffected.
The outflows ceased when we paused withdrawal service earlier. We are still working with partners to freeze many of the impacted assets, and have frozen around $3 billion thus far.
We will continue to provide further updates through official Binance channels as more verified information becomes available.
Binance's initial investigation suggests that the security incident may involve a compromised DevOps engineer’s laptop, which allowed an attacker to gain access to a service container and submit unauthorized withdrawal transactions. We have found no evidence of any wallet private key leak. We will share a detailed technical post-mortem once the investigation is complete and the facts are fully verified.
The estimated total impact sits at around $6.3B. We have worked with blockchain partners to freeze affected assets, with ~$3 billion frozen on-chain so far.
Binance will cover all losses from the SAFU fund and the company’s funds. User funds are safe. We will also publish an updated Proof of Reserves once the remediation is complete.
As an immediate precaution, Binance has:
- temporarily suspended deposits and withdrawals while security checks are completed;
- revoked the affected address authorisation;
- engaged law enforcement and blockchain intelligence partners to trace and recover funds.
Our teams are working around the clock to resolve this issue safely and thoroughly. We are working closely with our law enforcement partners to confirm the identity of these criminals and bring them to justice.
Please rely only on official Binance channels for updates. Please feel free to contact Binance Customer Support if you have any further questions.

Update: The current verified total frozen amount is around $3 billion.
Our teams continue to work closely with law enforcement, issuers, blockchain intelligence firms and industry partners to trace and freeze additional assets.
We will only share confirmed figures and will provide further updates as more verified information becomes available. User funds are safe.
anyway, here's our story, hmu if you have tips or are part of incident response 🥰 axios.com/2026/10/29/binance…

Today, Corridor is joining Cognition! Together, we’ll be taking Devin Security to the next level.
We started Corridor almost two years ago with the mission of accelerating secure and autonomous software development. Since then, we’ve seen security go from a niche concern to one of the most pressing issues of our time.
We’re grateful to our team, our customers, our investors, and everyone who’s supported us along the way. We can’t wait to show you what we build next!
Today, Cognition is acquiring @corridor.
Securing the world’s software is the most important problem in technology today.
Let’s get to work!
a week ago, everyone was freaking out about the internet going dark + doomsday.
today, we're all still here & the internet-wide meltdown everyone feared hasn't materialized.
welcome to the AI cybersecurity era — it's more nuanced than you'd probs expect.

Louder for those in the back! @FEC ONLY handles campaign finance reports which list raising and spending. We play zero role in administering the election. We don’t receive, maintain, or come close to dealing with voter files, voting machines or voting.
important reminder: "The FEC does not play a role in administering US elections and the outage should have no effect on voters' ability to cast ballots."
BREAKING: A hacker is attempting to breach the US Federal Election Commission's systems and that agency has had to 'temporarily shut down' its web-facing services as a result, according to an email seen by Reuters reut.rs/4imQyUu
CISA added CVE-2026-109618 and CVE-2026-109619 to the Known Exploited Vulnerabilities list on Monday night
But the federal cyber defense agency implied in comments to @TheRecord_Media that the PHP2Shell bugs were added because of attempts instead of successful exploitation
SITUATION UPDATE: Following GMO Internet's refusal to pay a $50M ransom, the hackers behind the breach have promised to trigger ransomware covertly planted on customers' PCs via the cloud. GMO is urging users to unplug network cables, and power off their PCs before noon today.
a 🤯 quote from a call today with a 40+ yr cyber veteran: "This is the worst outlook I've ever had, and it also is the most interesting thing I've ever seen in my life."
well, alrighty then
Replying to @Unit42_Intel
2/2 This led us to believe that it was exploitation of those vulnerabilities. We are unable to confirm that initial access is associated with the specific PHP2Shell CVEs. We have retracted our previous update from October 23.

‼️ “Unfortunately, enterprises still seem to not see the urgency across the board, decisions are stuck, CIO/CISO's have a lot on their plate.”
(fwiw, I’ve also been hearing + writing about the decision paralysis at orgs, it’s real)
It's been an eventful week. Multiple vulnerabilites in Internet facing software, coding repositories, examples of agent behavior that seem concerning and a flurry of security specialists with solutions that can partially solve your problem. There in lies the challenge. Given the state of IT and security infrastructure, no one solution works. Let's break it down:
1/3
1. Vulnerabilites are being found and will continue to be found as models get more capable, the fragmented nature of the effort denies us the opportunity for a comprehensive find and replace option.
2. Even if all vulnerabilities could be found instantly and patches available - we will be reliant on the ability of enterprises to deploy all these changes at speed. It is not clear what the collateral impact of all these patches will/could be to our infrastructure of deployed en masse.
We will need a hybrid patch approach.
3. Virtual patching(VP) is needed in conjunction with direct patching but for a comprehensive (VP) solve you have to be lucky enough to have "modern frontier defenders" (Cyber companies that have vaulted infrastructure that can create patches at speed and push content rapidly to protect their customers) you need them for your network traffic, your traffic to applications on the cloud, your WAF, your end point.
4. There will continue to be patches that will need to be deployed directly but virtual patching will take the heavy load off.
2/3 Medium term solve:
Unfortunately token economics and current cyber architectures will not allow for defender swarms to contend with an offensive attack launched using agents. (Some x pundits who aren't steeped in cyber should take heed). Yes, theoretically we should aspire to have these agentic swarms defend us when we are under attack, unfortunately an attack is a sniper moment, chained vulnerabilities, cloaked attack followed by swift exfiltration. It's a speed program not a brute force problem.
To solve for this, enterprises need to get their SOC architecture right, logs, feeds, cyber products orchestrated via a modern SOAR for swift response. Only then can we deploy agents to detect and remediate. In addition, enterprises need to modernize and dare I say platformize their perimeter stack to ensure consistency.
Unfortunately, enterprises still seem to not see the urgency across the board, decisions are stuck, CIO/CISO's have a lot on their plate. While some honestly have bit seen the scale of such a problem before and it's hard convincing the organization that one needs to open the floodgates on modernizing the IT and security infrastructure. So we will continue to see environments being brought down to patch today it's for PHP, tomorrow it will be for the next one.
3/3 AI deployments are the"wild wild west" - LLM capabilities are expanding faster than we can build products to secure them. Sure an agent will jump across guardrails in a research lab, which is a lesson for all of us to deploy agents securely. But there is a lag between the discovery, the availability of that in a public model and the time needed for the cyber industry to build governance or an antidote. And no, dear frontier lab friends, the world cannot just trust you to build the solve. The infrastructure industry in tech builds and the cyber industry secured and provides assurance to the boards and organizations around security and safety.
AI security is the new attack surface. CEOs (present company included) want AI adoption, getting the pace of adoption wrong could be the last decision we make, at the same time "deploying it wrong" could have the same consequence.
There are billions of dollars being spent on coding, is your coding harness secure? Start there. If agents can jump guardrails, they can hide stuff in code.
Validate business outcomes needed, test your user case and ensure agentic deployments are well guard railed. Deploy a second set of eyes to watch your deployments for drift, compliance and verifiability.
i was hearing about company decision paralysis on security all summer, including at black hat: axios.com/2026/08/11/ai-cybe…
would love to chat with people who are trying to learn more about cybersecurity on the side after last week's events.
taking short online classes? watching hours of youtube videos? calling your cyber friends? investing as a form of learning about the cyber market + threats?
hmu if that's you; signal in bio 📲
