OpenAI has begun rolling out a new Lockdown Mode to ChatGPT for eligible personal accounts to reduce the risk of data exfiltration arising from prompt injection attacks . The feature is primarily designed for people and organizations that handle sensitive data and require stricter protection guarantees. Lockdown Mode is available to logged-in users across Free, Go, Plus, and Pro, and self-serve ChatGPT Business plans. "Lockdown Mode is an optional advanced security setting that limits many tools and capabilities in OpenAI products that can connect to the web or external services," OpenAI said . "It is designed to reduce the risk of data exfiltration from prompt injection attacks by limiting outbound network requests, at the expense of disabling or limiting some useful features." The safeguards are aimed at hardening the attack surface against prompt injections, which continues to be a "frontier" problem impacting all large language models (LLMs...

Google has announced that it's rolling out a new set of features to its Chrome browser that gives users more control over their data when surfing the internet and protects them against online threats. "With the newest version of Chrome, you can take advantage of our upgraded Safety Check, opt out of unwanted website notifications more easily and grant select permissions to a site for one time only," the tech giant said . The improvements to Safety Check allow it to run automatically in the background, notifying users of the actions it has taken, such as revoking permissions for websites they no longer visit, and flagging potentially unwanted notifications. It's also designed to notify users of security issues that need to be addressed, while automatically revoking notification permissions from suspicious sites identified by Google Safe Browsing . "On Desktop, Safety Check will continue to notify you if you have any Chrome extensions installed that may pose...

Google on Thursday announced an enhanced version of Safe Browsing to provide real-time, privacy-preserving URL protection and safeguard users from visiting potentially malicious sites. “The  Standard protection mode for Chrome  on desktop and iOS will check sites against Google’s server-side list of known bad sites in real-time,” Google’s Jonathan Li and Jasika Bawa  said . “If we suspect a site poses a risk to you or your device, you’ll see a warning with more information. By checking sites in real time, we expect to block 25% more phishing attempts.” Up until now, the Chrome browser used a locally-stored list of known unsafe sites that’s updated every 30 to 60 minutes, and then leveraging a  hash-based approach  to compare every site visited against the database. Google  first revealed  its plans to switch to real-time server-side checks without sharing users’ browsing history with the company in September 2023. The reason for the change, the...

Microsoft has issued a warning about a significant flaw in the Internet Explorer browser that could allow hackers to control unprotected computers. The vulnerability permits hackers to inject malware into any system by tricking users into visiting malicious websites. This affects anyone using Internet Explorer (IE) versions 6 to 8. The exploit code for this bug has already been published. Although Microsoft has stated there is no current evidence of its use by criminals, they are "investigating" and working on a permanent fix, according to a report by the Daily Mail. Dave Forstrom, director of Microsoft's Trustworthy Computing group, said, "We're currently unaware of any attacks trying to use the claimed vulnerability or of customer impact." The bug targets how the browser manages a computer's memory when processing Cascading Style Sheets (CSS), which are design instructions that dictate the appearance of most web pages. Hackers can inject their own...
