Meta on Tuesday announced LlamaFirewall , an open-source framework designed to secure artificial intelligence (AI) systems against emerging cyber risks such as prompt injection, jailbreaks, and insecure code, among others. The framework , the company said, incorporates three guardrails, including PromptGuard 2, Agent Alignment Checks, and CodeShield. PromptGuard 2 is designed to detect direct jailbreak and prompt injection attempts in real-time, while Agent Alignment Checks is capable of inspecting agent reasoning for possible goal hijacking and indirect prompt injection scenarios. CodeShield refers to an online static analysis engine that seeks to prevent the generation of insecure or dangerous code by AI agents. "LlamaFirewall is built to serve as a flexible, real-time guardrail framework for securing LLM-powered applications," the company said in a GitHub description of the project. "Its architecture is modular, enabling security teams and developers to com...

Popular messaging app WhatsApp on Tuesday unveiled a new technology called Private Processing to enable artificial intelligence (AI) capabilities in a privacy-preserving manner. "Private Processing will allow users to leverage powerful optional AI features – like summarizing unread messages or editing help – while preserving WhatsApp's core privacy promise," the Meta-owned service said in a statement shared with The Hacker News. With the introduction of the latest feature, the idea is to facilitate the use of AI features while still keeping users' messages private. It's expected to be made available in the coming weeks. The capability, in a nutshell, allows users to initiate a request to process messages using AI within a secure environment called the confidential virtual machine (CVM) such that no other party, including Meta and WhatsApp, can access them. Confidential processing is one of the three tenets that underpin the feature, the others being - Enf...

WhatsApp has introduced an extra layer of privacy called Advanced Chat Privacy that allows users to block participants from sharing the contents of a conversation in traditional chats and groups. "This new setting available in both chats and groups helps prevent others from taking content outside of WhatsApp for when you may want extra privacy," WhatsApp said in a statement. The optional feature, when enabled, prevents others from exporting chats, auto-downloading media to their phone, and using messages for artificial intelligence (AI) features. However, it's worth noting users can still take individual screenshots, or manually download the media. The popular messaging service said the feature is "best used" when engaging in sensitive conversations with groups where it's possible that users may not know everyone closely. The feature, WhatsApp said, is rolling to all users who are on the latest version of the application. The disclosure comes as the ...

Google on Tuesday revealed that it will no longer offer a standalone prompt for third-party cookies in its Chrome browser as part of its Privacy Sandbox initiative. "We've made the decision to maintain our current approach to offering users third-party cookie choice in Chrome, and will not be rolling out a new standalone prompt for third-party cookies," Anthony Chavez, vice president of Privacy Sandbox at Google, said . "Users can continue to choose the best option for themselves in Chrome's Privacy and Security Settings." Back in July 2024, the tech giant said it had abandoned its plans to deprecate third-party tracking cookies and that it intends to roll out a new experience instead that lets users make an informed choice. Google said feedback from publishers, developers, regulators, and the ads industry has made it clear there are "divergent perspectives" on making changes that could affect the availability of third-party cookies. In its...

Apple has been hit with a fine of €150 million ($162 million) by France's competition watchdog over the implementation of its App Tracking Transparency (ATT) privacy framework. The Autorité de la concurrence said it's imposing a financial penalty against Apple for abusing its dominant position as a distributor of mobile applications for iOS and iPadOS devices between April 26, 2021 and July 25, 2023. ATT, introduced by the iPhone maker with iOS 14.5, iPadOS 14.5, and tvOS 14.5, is a framework that requires mobile apps to seek users' explicit consent in order to access their device's unique advertising identifier (i.e., the Identifier for Advertisers or IDFA ) and track them across apps and websites for purposes targeted advertising. "Unless you receive permission from the user to enable tracking, the device's advertising identifier value will be all zeros and you may not track them," Apple notes on its website. "While you can display the AppTr...

Malicious actors are exploiting Cascading Style Sheets (CSS), which are used to style and format the layout of web pages, to bypass spam filters and track users' actions. That's according to new findings from Cisco Talos, which said such malicious activities can compromise a victim's security and privacy. "The features available in CSS allow attackers and spammers to track users' actions and preferences, even though several features related to dynamic content (e.g., JavaScript) are restricted in email clients compared to web browsers," Talos researcher Omid Mirzaei said in a report published last week. The insights build upon previous findings from the cybersecurity company about a spike in email threats leveraging hidden text salting in the second half of 2024 with an aim to get around email spam filters and security gateways. This technique particularly entails using legitimate features of the Hypertext Markup Language (HTML) and CSS to include commen...

The GSM Association (GSMA) has formally announced support for end-to-end encryption (E2EE) for securing messages sent via the Rich Communications Services (RCS) protocol, bringing much-needed security protections to cross-platform messages shared between Android and iOS platforms. To that end, the new GSMA specifications for RCS include E2EE based on the Messaging Layer Security (MLS) protocol via what's called the RCS Universal Profile 3.0 . "The new specifications define how to apply MLS within the context of RCS," Tom Van Pelt, technical director of GSMA, said . "These procedures ensure that messages and other content such as files remain confidential and secure as they travel between clients." This also means that RCS will be the first "large-scale messaging service" to have support for interoperable E2EE between different client implementations from different providers in the near future. It's worth noting that Google's own implemen...

Google has announced the rollout of artificial intelligence (AI)-powered scam detection features to secure Android device users and their personal information. "These features specifically target conversational scams, which can often appear initially harmless before evolving into harmful situations," Google said . "And more phone calling scammers are using spoofing techniques to hide their real numbers and pretend to be trusted companies." The company said it has partnered with financial institutions to better understand the nature of scams customers are encountering, thereby allowing it to devise AI models that can flag suspicious patterns and deliver real-time warnings over the course of a conversation without sacrificing user privacy. These models run completely on-device , alerting users in the event of a likely scam. Users then have an option to either dismiss or report and block the sender. The setting is enabled by default and applies only to conversatio...

Firefox browser maker Mozilla on Friday updated its Terms of Use a second time within a week following criticism overbroad language that appeared to give the company the rights to all information uploaded by users.
