ChatGPT Share-Link Flaw Could Expose Private Chats and Hijack Sessions

 

A recently disclosed vulnerability in ChatGPT demonstrated how a maliciously crafted shared conversation link could execute attacker-controlled code within a victim’s logged-in session. The issue was identified by security researchers at Parameter, who demonstrated that the flaw could expose private conversations and allow actions to be performed using the victim’s authenticated account. The vulnerability was reported to OpenAI through its bug bounty program on October 18 and was remediated eight days later. OpenAI classified the issue as P1, its highest severity rating. 

The attack required no software installation, workspace membership, or separate login through the attacker. A victim could receive the malicious ChatGPT share link through email, a messaging platform, a support ticket, or social media. In the most reliable version of the attack, the victim opened the link and clicked the Preview button once. In a later variant, Preview opened automatically, meaning that merely opening the link was sufficient to trigger the attack. 

Once triggered, the malicious code executed within the victim’s ChatGPT session and could interact with ChatGPT’s signed-in APIs. The researchers showed that it could list recent conversations, access a private chat that had never been shared, and transmit part of its contents to an external server under their control. Because the code operated within an authenticated session, it had the potential to perform actions on behalf of the affected user. 

The vulnerability resulted from a combination of weaknesses in ChatGPT’s web architecture. ChatGPT’s Preview feature renders shared HTML in a sandboxed frame on a separate domain, intended to isolate it from the main ChatGPT application. However, an interactive graph in the shared conversation loaded the MathLive mathematics library into the main ChatGPT page. This library retained a message listener that accepted keyboard-related messages from any sender without verifying their origin. The researchers exploited this behavior to send raw HTML from the isolated Preview frame into the trusted main ChatGPT page. 

OpenAI reproduced both the code-execution and private-chat proof-of-concept demonstrations and implemented fixes across two versions of its web frontend. By October 26, both versions rejected the messages on which the attack depended. Parameter published its technical analysis on October 28 after the remediation, and OpenAI awarded a total of $5,000 through its bug bounty program. The researchers also noted that the issue reflected broader weaknesses in message-origin validation, HTML handling, and sandboxing, rather than a problem that could be resolved simply by blocking third-party scripts such as YouTube.

Critical Linux Kernel Vulnerability Could Allow Hackers to Gain Remote Root Access


A critical security vulnerability in the Linux kernel could allow attackers to remotely take control of vulnerable servers and execute commands with root privileges. Security researchers at Anthropic have developed an exploit demonstrating how the flaw can be used to compromise Linux systems running Multipath TCP (MPTCP) listeners.

The vulnerability, tracked as CVE-2026-98432, has received a critical severity rating of 9.8 out of 10 from the Linux kernel CVE team. It affects Linux kernel versions dating back to 4.4 and could put several widely used Linux distributions at risk.

About the problem

The security issue is caused by a use-after-free vulnerability in the Linux kernel’s IPv4 TCP networking code. It occurs because of a race condition during the handling of TCP connection requests.

The vulnerability affects both regular TCP connections and Multipath TCP (MPTCP). MPTCP allows a single network connection to use multiple network paths simultaneously, improving connection reliability and performance.

Researchers at Anthropic demonstrated that the flaw could be exploited remotely without authentication on servers running MPTCP listeners. Their exploit was developed using an unreleased Claude AI model and reportedly took around 53 minutes to achieve remote code execution with root privileges. 

The exploit also managed to bypass Kernel Address Space Layout Randomization (KASLR), a security mechanism designed to make memory-based attacks more difficult.

Another concern involves Go 1.24, which enables MPTCP by default for TCP listeners on Linux when the underlying kernel supports the feature. This means some Go-based applications could expose vulnerable services without administrators being aware of it.

Who is impacted?

The vulnerability affects multiple Linux distributions, including Ubuntu, Red Hat Enterprise Linux (RHEL) and Rocky Linux. While the Linux kernel issue can also be triggered through ordinary TCP connections, publicly demonstrated remote root exploitation has so far focused on systems running MPTCP listeners.

Red Hat has assessed the vulnerability as a complex exploitation risk that could result in a denial-of-service condition, assigning it a lower severity score of 5.9.

How to address

The vulnerability has been fixed in the upstream Linux kernel, with patches also backported to maintained kernel branches. However, security updates were still pending for several distributions as of October 30, 2026.

Rocky Linux support provider CIQ has also recommended temporary firewall protections using nftables to block IPv4 TCP packets containing IP options. But simply disabling MPTCP is not sufficient because the underlying vulnerability can also be triggered through ordinary TCP traffic.

There are currently no confirmed reports of CVE-2026-98432 being exploited in real-world attacks.

Polymarket Traders Lose More Than $2 Million in Supply Chain Attack Involving DebugBear

 

Polymarket has halted trading on its global marketplace on October 29 after users reported over $2 million being withdrawn without authorisation. The issue was caused when a third party provider was compromised and malicious code was injected which exploited authorised user sessions to withdraw funds. 

The prediction market first put their global marketplace into cancel only mode. However trading resumed around an hour later after they said they had “identified and resolved the issue.” Polymarket confirmed that they had reported the incident to law enforcement and would compensate those affected. 

They have not yet identified the third party provider or confirmed how much was lost. The attack was attributed to malicious JavaScript from DebugBear, a UK based website performance monitoring company. Polymarket’s US marketplace was not impacted. DebugBear admitted they were currently responding to a security incident and requested that customers using their real user monitoring (RUM) product remove their script from their website. They also said specialised incident response teams had been deployed. 

A copy of the malicious JavaScript was obtained by cybersecurity firm Hudson Rock. They identified that the script was searching for trading tools and portfolio data. Depending on the account type, the script would attempt to sell positions and move the funds or move the position tokens directly to the attacker controlled address. Although the code was looking for credential related data, Hudson Rock noted that there was no routine to pass on passwords, seed phrases, private keys or credential maps to their reporting endpoint. 

This attack was exploiting existing permissions. The researchers identified a production build of the Polymarket platform with a timestamp of 17:59 UTC. This included a note that the DebugBear script had been removed. It is unclear how much was stolen. Hudson Rock analysed a screenshot that showed around $2.19 million at an address hard-coded into the malicious script as a fallback destination, but cautioned that the figure was not a verified loss total. 

Blockchain security firm GoPlus estimated the losses at roughly $2.71 million had been stolen. They identified there were 710 deposit wallets and 731 addresses within the main attack path. This does not indicate how many individuals were affected. Arkham data shows there was a suspected attackers wallet with around $2.65 million. Hudson Rock have not identified how the malicious code was added or how many users were affected. 

Their investigation has also not found any evidence that other DebugBear customers were targeted. This incident happened on the same day that Binance suffered a hack of around $6 billion, which blockchain intelligence firms attributed to North Korea. Polymarket had also disclosed a third-party security breach in June, when a malicious script was injected into its frontend and reportedly resulted in losses of around $3 million.

Florida Reports Major Data Breach Affecting 4.9 Million Financial Aid Applicants


The Florida Department of Education (FLDOE) has disclosed a data breach involving its student financial aid website that may have exposed the sensitive personal information of approximately 4.9 million individuals. The compromised information reportedly includes Social Security numbers, names, residential addresses, phone numbers, email addresses, genders and dates of birth. According to the department, unauthorized criminal access to the Florida Student Financial Aid website was discovered on October 19, 2026. 

The agency publicly disclosed the incident on October 29, describing it as a security breach involving unauthorized access to a system containing personal information. The exact method used to gain access and the identity of those responsible have not been disclosed. In a statement issued by the Florida Department of Education, it was noted that individuals who had used the state's financial aid portal may have been affected by the incident. 

The website facilitates the application process for scholarship, grant, and other financial assistance programs, including the lottery-funded Bright Futures scholarship program. After identifying the intrusion, the department activated its cybersecurity response procedures. It has been determined that the unauthorized activity was stopped, contained, and the affected systems were secured. 

As part of the response, the Florida Digital Service and the Florida Department of Law Enforcement are also involved, and the issue has been reported to the Attorney General's Office. According to information reported by The Record, the information exposed may pertain to nearly five million Florida students who applied for financial aid. 

This incident is particularly concerning as Social Security numbers and dates of birth are included, as such information can be exploited for identity theft, fraudulent account creation, and other financial crimes. Rather than affecting the entire Florida Student Financial Aid network, the department believes that the breach was limited to the website. Despite this, the investigation is still ongoing, and officials have not confirmed a breakdown of the affected records or explained how the unauthorized party entered the system. 

The FLDOE has taken the financial aid website offline as part of the response. During the recovery process and security measures, other departmental websites and online services may experience temporary disruptions. Although sensitive personal information was exposed in the incident, the department clarified that it did not affect the administration of financial aid.

Scholarship and grant eligibility, as well as student loan services administered by the department, are expected to continue without delay in spite of the exposure of sensitive personal information. A warning has been issued to potentially affected individuals to monitor their financial and online accounts for unusual activity and to regularly review their credit reports. 

In addition, the department recommended that students consider placing an alert or placing a credit freeze with the major credit bureaus to prevent identity fraud. Currently, the investigation has not been able to determine who is responsible for the intrusion or how the financial aid website was accessed. No information has been provided by the Florida Department of Education as to whether the breach involved stolen credentials, exploited software vulnerabilities, or used another approach to attack. 

Additionally, the authorities have not disclosed any further information concerning the nature of the intrusion, but stated that additional information will be provided once verified findings are available. The breach is not the only recent cyberattack involving government educational systems in the United States. 

Separate data breaches were reported by the California Department of Education approximately one week earlier, which involved information associated with children who had been enrolled in public schools for the previous three years. Despite the lack of connection between these two incidents, the disclosures have raised concerns about the security of sensitive educational information. This year, Florida has also experienced several security breaches relating to government organizations. 

During September, the Department of Motor Vehicles reported a breach involving a prominent hacking group. According to The Record, the hackers continued to advertise the stolen DMV information on cybercriminal forums throughout October.

In a separate incident, a central Florida county experienced significant internet service disruption following an alleged cyberattack. The increasing number of incidents involving public institutions emphasizes the risks associated with large amounts of personal information stored in government databases. 

A majority of educational and administrative portals maintain records containing personal information, which may make unauthorized access particularly concerning when the information relates to millions of individuals. In accordance with Florida's law requiring notification of data breaches, Section 501.171 of the state statutes requires organizations covered by the law to implement reasonable measures to protect electronic personal information. 

There is generally a 30 day notification period for a breach that affects 500 or more Florida residents in order for the Department of Legal Affairs to be notified of the breach. According to applicable legal exceptions, affected individuals must also be notified as soon as possible. The incident occurs in the context of a wider increase in reported data exposures. 

At least 3,43 million people were affected by 5,429 breach notification filings in the first half of 2026, according to the Privacy Rights Clearinghouse, which covered 1,969 distinct incidents. As a result, 33.8% of the reported breach incidents were unable to be determined from public filings during this period, compared with 22.6% in 2022. There remains a priority for the Florida Department of Education in determining the extent of the exposure. 

In the ongoing criminal investigation, the final number of affected individuals, the method of intrusion, and the identity of the unauthorized party are still unknown. Public-sector systems that store sensitive personal and financial information face increasing security risks as a result of this incident. 

There will be a continuing need to determine how the attackers gained access to the system as well as ensuring affected individuals are given timely protection as the investigation proceeds.

North Korean Hackers Drain $6.3 Billion from Binance in Record-Breaking Crypto Theft

 



Hackers tied to North Korea stole roughly $6.36 billion from Binance on Wednesday, stripping the world's largest cryptocurrency exchange of funds across ten blockchains in a heist that blockchain intelligence firms are calling the largest crypto theft in history.

The attack, which began at 8:05 p.m. UTC on October 29, moved faster than most exchange security teams could respond. The bulk of the money was gone within 20 minutes.

Binance suspended deposits and withdrawals shortly after detecting the breach and said user funds would be covered in full. "Investigating a potential security issue," the exchange wrote in an early-evening post, adding that user assets were safe. By late that night, a coalition of blockchain infrastructure firms had frozen roughly $3 billion of the stolen assets, though more than $2.4 billion remained in the attacker's control as of press time.


How They Got In

Blockchain intelligence firm TRM Labs, which traced the attack in near real-time, said the intrusion bore the hallmarks of TraderTraitor, the North Korean state-sponsored hacking unit that the FBI also attributed to February's $1.5 billion Bybit breach.

The preparation started at least 36 hours before the theft. TRM Labs found that the attackers funded an operator wallet with small withdrawals from Tornado Cash, a crypto mixing service, then ran test transactions across wallets they controlled. In the day before the main theft, the attackers rehearsed the final version of their code on a third wallet before installing it on a live Binance hot wallet.

The technical method on Ethereum was particularly precise. The attackers used EIP-7702, an account delegation feature introduced in a recent Ethereum upgrade, to effectively convert a Binance hot wallet into a sweeper they controlled. A single transaction carried 50 pre-signed authorizations; one matched the wallet's transaction count exactly, granting the attackers the ability to sweep new incoming deposits for hours after the initial theft, all the way until 11:56 p.m. UTC.

On nine other blockchains, including Bitcoin, Tron, XRP Ledger, Solana, Arbitrum, and several Ethereum layer-2 networks, wallets sent funds through standard signed transfers during the same window. TRM's analysis concluded the most likely explanation was that the attacker had somehow obtained the ability to instruct Binance's hot wallet signing infrastructure to authorize transactions of their choosing. Binance has not yet published a root cause analysis.


What Was Taken

The breakdown by chain is staggering. Ethereum accounts for the largest slice: about $3.79 billion, including 200,630 ETH and roughly 1.875 billion USDT. Bitcoin follows with 18,270 BTC worth approximately $1.47 billion. Tron contributed about $628 million, primarily USDT, and XRP Ledger added 233 million XRP worth around $296 million. The remaining losses were spread across Solana, Arbitrum, Optimism, Base, Avalanche, and Polygon.

At those figures, the theft dwarfs every previous crypto hack on record by a considerable margin. The Bybit breach in February 2025, which itself broke every prior record, involved $1.5 billion. This attack is roughly four times larger.


The Freeze Race

Within hours of the theft, stablecoin issuers and blockchain governance bodies began freezing assets. Tether moved first, blacklisting 971 million USDT across wallets traced to the attacker at 9:01 p.m. UTC. Circle followed three minutes later with a freeze on $823 million in USDC, acting in coordination with law enforcement. Ripple froze 40.5 million RLUSD at 10:01 p.m. The Arbitrum Security Council executed forced transfers of 8,426 ETH and 74.6 million ARB tokens after midnight.

By 11:35 p.m. UTC, Binance said the verified total of frozen assets had reached $2.54 billion. TRM Labs placed the figure closer to $2.7 billion by 12:30 a.m. the following morning.

The attacker, however, moved quickly to convert portions of the stolen funds. Some USDT was swapped for ETH at a discount of more than 10%, and the attacker used Aave, a decentralized lending protocol, to borrow ETH against frozen stablecoin positions. As of the morning of October 30, the attacker still held more than 420,000 ETH and all 18,270 BTC, assets beyond the reach of any issuer's freeze function.


North Korea's Crypto Playbook

The FBI said it was aware of the incident and working with partners to assess the activity. The U.S. Secret Service had not responded to a request for comment at time of publication.

The timing fits a pattern that intelligence analysts have tracked closely. Chainalysis reported that North Korean operatives stole about $2 billion in cryptocurrency throughout 2025. TRM Labs found that two North Korea-linked groups accounted for three-quarters of all crypto hack losses in the first quarter of 2026 alone. The funds are widely believed to support Pyongyang's weapons programs, which have been cut off from conventional financial markets through international sanctions.

TRM Labs said it expects the attacker to route remaining funds through cross-chain bridges, swap services, and over-the-counter brokers in the coming weeks, and said it was monitoring those flows in real time.



Cyberattack Clouds Political Spending Transparency in America

 

A cyberattack targeting the United States Federal Election Commission disrupted access to campaign finance disclosures shortly before the November 3 midterm elections, prompting concerns about electoral transparency. The commission suspended its filing systems for approximately 41 hours after an unidentified malicious actor attempted to gain access. This interruption prevented campaigns and political organizations from submitting certain time-sensitive financial reports, temporarily limiting public oversight of election funding. The incident concerned financial disclosure infrastructure; the available information did not establish any interference with voting systems or election results. 

The disruption affected disclosures ordinarily required within 24 or 48 hours, producing an information gap during a particularly consequential period of campaign activity. Millions of dollars in political financing may have remained outside immediate public scrutiny while the systems were unavailable. Nevertheless, delayed reporting does not demonstrate that contributions were permanently concealed or that donors deliberately exploited the interruption. Limited public information about the attacker, the techniques employed, and the underlying motive prevented definitive conclusions regarding the incident’s origins, scope, or broader political implications and consequences. 

Transparency advocates emphasized that the timing substantially increased the significance of the outage. OpenSecrets executive director Hilary Braseth argued that delayed disclosure undermines meaningful public access to campaign finance information. Research director Brendan Glavin indicated that political spending before the interruption had reached approximately $50 million per day. At that scale, even a relatively brief suspension can impede efforts by journalists, researchers, and voters to identify financial interests behind election messaging. Information disclosed after voting may have less practical value for assessing candidates and their supporters. 

The incident also renewed attention to SuperPACs and technology interests seeking to influence public policy through election spending. Political organizations supporting artificial intelligence development have invested substantial resources in promoting sympathetic candidates and challenging opponents. These activities coincide with disputes over data center construction, local infrastructure pressures, and potential regulatory restrictions. Electoral outcomes may therefore affect both technology policy and future investment decisions. Such connections underscore the importance of prompt financial disclosure, but they provide no basis for attributing responsibility for the cyberattack to these interests. 

Speculation that the outage facilitated undisclosed political contributions remained unsubstantiated. Political spending researcher Molly White expressed concern about diminished visibility into rapidly increasing expenditures while acknowledging uncertainty surrounding the incident. The episode demonstrates that effective campaign finance oversight depends on resilient reporting infrastructure as well as legal disclosure requirements. Authorities must therefore balance cybersecurity precautions with the need to maintain accessible public records. Reliable systems, timely reporting, and clear communication are essential to preserving scrutiny when voters are preparing to make consequential decisions about political representation.
