OpenAI Launches Lockdown Mode to Shield ChatGPT from Prompt Injection Attacks
BitcoinWorld OpenAI Launches Lockdown Mode to Shield ChatGPT from Prompt Injection Attacks OpenAI has introduced a new security feature called Lockdown Mode, designed to protect ChatGPT users from prompt injection attacks — a growing vulnerability where malicious instructions are hidden inside web content, uploaded files, or third-party data sources. The feature, announced on June 6, 2026, is rolling out to self-serve ChatGPT Business accounts and eligible personal accounts. What Lockdown Mode Disables When activated, Lockdown Mode restricts several ChatGPT capabilities to reduce the risk of data exfiltration. Specifically, it disables live web browsing, restricting the model to cached content only. It also blocks the retrieval and display of images from the web, though users can still generate images using DALL-E. Additionally, deep research features and agent mode are turned off. OpenAI emphasized that Lockdown Mode is not a silver bullet. The company noted that prompt injections could still appear in cached web content or uploaded files, potentially affecting response accuracy or behavior. However, the feature aims to significantly reduce the likelihood that sensitive data is inadvertently shared during an attack. Who Needs Lockdown Mode Lockdown Mode is not intended for general consumers. OpenAI explicitly states it is designed for people and organizations that handle sensitive data and require stricter protection from data exfiltration risks related to prompt injection. This includes industries such as legal, healthcare, finance, and government, where confidential information is frequently processed through AI tools. Why Prompt Injection Matters Prompt injection attacks exploit the way large language models interpret instructions. An attacker can embed hidden commands within a webpage, email, or document that, when processed by the AI, cause it to reveal private information, bypass security controls, or perform unintended actions. As enterprises increasingly integrate AI into workflows, the attack surface for such exploits has expanded, making dedicated countermeasures like Lockdown Mode a necessary addition to the security toolkit. Industry experts have long called for more robust safeguards. The introduction of Lockdown Mode signals that OpenAI is responding to real-world deployment challenges, particularly in regulated environments where compliance and data governance are non-negotiable. Comparison with Existing Security Measures Lockdown Mode complements existing protections like API rate limiting, content filtering, and data retention controls. However, it is the first feature specifically targeting the prompt injection vector at the application level. Unlike broader security policies that apply to all users, Lockdown Mode is opt-in and context-specific, allowing organizations to balance functionality with risk tolerance. Other AI providers, including Google and Anthropic, have introduced similar isolation features for their enterprise offerings, but OpenAI’s move is notable given ChatGPT’s widespread adoption across both business and personal use cases. Implications for Enterprise AI Adoption The launch of Lockdown Mode may accelerate enterprise adoption by addressing one of the most cited concerns: data leakage. For organizations that have hesitated to deploy generative AI due to security fears, this feature provides a tangible layer of control. It also sets a precedent for how AI companies can design safety features that are practical rather than purely theoretical. However, the limitations are clear. Lockdown Mode does not eliminate all prompt injection risks, and organizations must still implement comprehensive data handling policies, employee training, and monitoring systems. OpenAI’s candid acknowledgment of these gaps is a sign of maturity in the industry, but it also underscores that security remains an ongoing challenge. Conclusion OpenAI’s Lockdown Mode represents a targeted response to a specific and growing threat in AI security. While not a complete solution, it offers a meaningful layer of protection for users handling sensitive data. As prompt injection techniques evolve, features like this will likely become standard in enterprise AI platforms. For now, Lockdown Mode gives organizations a practical tool to reduce risk without abandoning the productivity gains that ChatGPT provides. FAQs Q1: What is a prompt injection attack? A prompt injection attack occurs when malicious instructions are hidden within content that an AI model processes, such as a webpage or uploaded file. The AI may then follow those hidden instructions, potentially exposing sensitive data or performing unauthorized actions. Q2: Will Lockdown Mode affect regular ChatGPT usage? Yes, but only for specific features. Lockdown Mode disables live web browsing, image retrieval from the web, deep research, and agent mode. Users can still generate images and access cached content. It is designed for high-security environments, not everyday use. Q3: Is Lockdown Mode available to all ChatGPT users? No. Lockdown Mode is currently rolling out to self-serve ChatGPT Business accounts and eligible personal accounts. OpenAI has not announced a timeline for broader availability.

Tether appoints independent director to Twenty One Capital board, restoring audit committee
The vacant audit committee seat on Twenty One Capital’s board has been filled by Tether International. The company designated an independent director that meets SEC and NYSE standards. Twenty One Capital’s (XXI) audit committee now has all the members it needs after Tether appointed a new independent director. Why was Twenty One Capital missing a director? The spot on Twenty One Capital’s (XXI) audit committee became empty after Tether purchased all 89.1 million shares SoftBank held in XXI for approximately $711 million on May 20. The deal gave Tether uncontested control as the majority shareholder of the Bitcoin treasury company, which holds more than 43,500 BTC. Once the deal closed , SoftBank’s representatives had to leave the board, including the one that served on the audit committee. Tether has now filled that spot with an independent director that it says meets the tough independence rules. The rules in question come from the Securities Exchange Act (Rule 10A-3) and the NYSE Listed Company Manual (Section 303A.02). These rules are designed to make sure audit committee members can oversee the company fairly without conflicts of interest. Paolo Ardoino, Tether’s CEO, said in the announcement that a great deal of rigor was put into finding the best candidate to deliver thorough and independent oversight. “The strength of the oversight needs to match the strength of the balance sheet,” Ardoino said, but Tether did not reveal the name of the new director in its announcement An audit committee is a group of board members who oversee a company’s financial reporting. The NYSE, requires listed firms to have at least three independent members on this committee. XXI is placed second among publicly traded corporate Bitcoin holders, trailing only Strategy (formerly MicroStrategy). Twenty One Capital places second among publicly listed Bitcoin treasury firms. Source: BitcoinTreasuries,net Independent board oversight is especially important now that Tether has consolidated its position. The stablecoin issuer already held voting control through XXI’s Class B shares and maintained approval authority over Bitcoin sales, mergers exceeding $1 million, and executive appointments. What are XXI’s next plans? Tether has proposed combining XXI with Jack Mallers’ Bitcoin payments company Strike and mining firm Elektron Energy. The three-way merger , first proposed in late April 2026, would create a vertically integrated Bitcoin business that includes treasury accumulation, payments, lending, and mining operations. Elektron manages about 50 exahashes per second (EH/s) of mining power. That is roughly 5% of the entire Bitcoin network. The platform has already mined more than 5,500 Bitcoins. Twenty One Capital launched in December 2025 through a SPAC merger with Cantor Equity Partners and trades on the NYSE under the ticker XXI. The merger has several hurdles surrounding its governance. For example, Jack Mallers currently serves as CEO of both Twenty One Capital (XXI) and Strike. The dual role is a conflict of interest that will require special review and a vote by minority shareholders. Raphael Zagury, the CEO of Elektron Energy, is a defendant in active lawsuits filed by Swan Bitcoin in California and the UK. Swan alleges that Zagury and other former executives conspired with Tether in 2024 to take over a mining joint venture. Tether has announced its intention to vote in favor of the mergers, but no final terms, closing timelines, or formal merger agreements have been signed or publicly released.

Here’s How Much BTC, ETH, XRP Have Dumped Since ‘Crypto President’ Trump Took Office
It’s safe to say that the cryptocurrency market has seen better days. In fact, such days were promised by the current US President, Donald Trump. And, for some time, they were here. Now, though, we are far behind, with the prices of almost all digital assets trading below his inauguration day and even lower than the pre-election weeks. Trump’s Major Promises Remember 2024? It was a highly eventful year, especially when it came down to the presidential election. On one hand, we had Kamala Harris, who was expected to continue many of Joe Biden’s policies, including those against the cryptocurrency industry. On the other hand, we had Donald Trump. Although his history with bitcoin and co was not very pleasant from his first time in office, he tried to make amends and started praising the asset class. Moreover, he started calling himself the ‘crypto president,’ and attended the largest Bitcoin conference in the US, where he had a passionate speech about BTC and how he would personally fire then-SEC Chair Gary Gensler (even though he can’t really). Hell, he even paid for a burger in New York with bitcoin. In addition, he made multiple grand promises about how the US will become the global hub for the industry, that all remaining bitcoin should be mined in the States, and that there will be a national BTC strategy reserve . The community was quickly sold, as they hadn’t seen anything like this in the past. They were used to ignorance or hatred from the White House. Consequently, prominent names from the industry started throwing funds toward his campaign in the hope of a better future for us all. Reality Check: 18 Months Later Given his promises, the entire market skyrocketed in the months after Trump’s landslide victory in the elections. The hype was real, but so were the price pumps. Then came the highly controversial launch of two meme coins linked to him and his wife, but we won’t even go down that rabbit hole here. We are only going to mention that they launched just days before his inauguration. Prices kept pumping, for the most part, excluding the ‘Liberation Day’ fiasco and the mid-year drop, but BTC, ETH, XRP, and many other alts still managed to post new ATHs by October. Things were looking up. And then it all went down the crapper. The single-largest liquidation day in early October was just the beginning, as BTC kept dropping. Long story short, bitcoin plunged to $59,000 on Friday, which was its lowest position since before the elections. Most crypto assets have done the same, in a more painful manner. But the numbers since the inauguration – the date that the so-called ‘crypto president’ officially returned to the White House, where he was supposed to fulfill his many promises – are even worse, as the tweet below will show. Crypto prices since Trump took office: $BTC -44% $ETH -49% $XRP -68% $SOL -77% $DOGE -79% $AVAX -82% $ADA -85% $SUI -86% $ENA -92% $APT -93% $TRUMP -97.7% $MELANIA -99.5% WE KEEP WINNING RIGHT .. — Crypto Tony (@CryptoTony__) June 5, 2026 The post Here’s How Much BTC, ETH, XRP Have Dumped Since ‘Crypto President’ Trump Took Office appeared first on CryptoPotato .
