Cybersecurity researchers have disclosed a zero-click flaw in OpenAI ChatGPT's Deep Research agent that could allow an attacker to leak sensitive Gmail inbox data with a single crafted email without any user action. The new class of attack has been codenamed ShadowLeak by Radware. Following responsible disclosure on June 18, 2025, the issue was addressed by OpenAI in early August. "The attack utilizes an indirect prompt injection that can be hidden in email HTML (tiny fonts, white-on-white text, layout tricks) so the user never notices the commands, but the agent still reads and obeys them," security researchers Zvika Babo, Gabi Nakibly, and Maor Uziel said . "Unlike prior research that relied on client-side image rendering to trigger the leak, this attack leaks data directly from OpenAI's cloud infrastructure, making it invisible to local or enterprise defenses." Launched by OpenAI in February 2025, Deep Research is an agentic capability built into ...

Threat actors with suspected ties to Russia have been observed taking advantage of a Google account feature called application specific passwords (or app passwords) as part of a novel social engineering tactic designed to gain access to victims' emails. Details of the highly targeted campaign were disclosed by Google Threat Intelligence Group (GTIG) and the Citizen Lab, stating the activity seeks to impersonate the U.S. Department of State.  "From at least April through early June 2025, this actor targeted prominent academics and critics of Russia, often using extensive rapport building and tailored lures to convince the target to set up application specific passwords (ASPs), GTIG researchers Gabby Roncone and Wesley Shields said . "Once the target shares the ASP passcode, the attackers establish persistent access to the victim's mailbox." The activity has been attributed by Google to a threat cluster it tracks as UNC6293, which it says is likely affiliate...

Google has revealed a new multilingual text vectorizer called  RETVec  (short for Resilient and Efficient Text Vectorizer) to  help detect  potentially harmful content such as spam and malicious emails in Gmail. "RETVec is trained to be resilient against character-level manipulations including insertion, deletion, typos, homoglyphs, LEET substitution, and more," according to the  project's description  on GitHub. "The RETVec model is trained on top of a novel character encoder which can encode all UTF-8 characters and words efficiently." While huge platforms like Gmail and YouTube rely on text classification models to spot phishing attacks, inappropriate comments, and scams, threat actors are known to devise counter-strategies to bypass these defense measures. They have been observed resorting to adversarial text manipulations, which range from the use of homoglyphs to keyword stuffing to invisible characters. RETVec , which works on over 100 langua...

Google has announced the general availability of client-side encryption (CSE) for Gmail and Calendar, months after  piloting the feature  in late 2022. The data privacy controls enable "even more organizations to become arbiters of their own data and the sole party deciding who has access to it," Google's Ganesh Chilakapati and Andy Wen  said . To that end, users can send and receive emails or create meeting events within their organizations or to other external parties in a manner that's encrypted "before it reaches Google servers." The company is also making available a decrypter utility in beta for Windows to decrypt client-side encrypted files and emails exported via its Data Export tool or Google Vault. macOS and Linux versions of the decrypter are expected to be released in the future. The development follows the  rollout of CSE  to other products such as Google Drive, Docs, Slides, Sheets, and Meet. The solution, the tech behemoth said, is ai...

Google on Friday announced that its client-side encryption for Gmail is in beta for Workspace and education customers as part of its efforts to secure emails sent using the web version of the platform. The development comes at a time when concerns about online privacy and data security are at an all-time high, making it a welcome change for users who value the protection of their personal data. To that end, Google Workspace Enterprise Plus, Education Plus, and Education Standard customers can apply to sign up for the beta until January 20, 2023. It's not available to personal Google Accounts. "Using client-side encryption in Gmail ensures sensitive data in the email body and attachments are indecipherable to Google servers," the company  said  in a post. "Customers retain control over encryption keys and the identity service to access those keys." It is important to know that the latest safeguards offered by Gmail is different from end-to-end encryption. ...

Cybersecurity researchers today uncovered a new advanced version of ComRAT backdoor, one of the earliest known backdoors used by the Turla APT group, that leverages Gmail's web interface to covertly receive commands and exfiltrate sensitive data. "ComRAT v4 was first seen in 2017 and known still to be in use as recently as January 2020," cybersecurity firm ESET said in a report shared with The Hacker News. "We identified at least three targets: two Ministries of Foreign Affairs in Eastern Europe and a national parliament in the Caucasus region." Turla , also known as Snake, has been active for over a decade with a long history of the watering hole and spear-phishing campaigns against embassies and military organizations at least since 2004. The group's espionage platform started off as Agent.BTZ , in 2007, before it evolved to ComRAT , in addition to gaining additional capabilities to achieve persistence and to steal data from a local network. It...

A few hours ago the company announced its "non-shocking" plans to shut down Google+ social media network following a "shocking" data breach incident. Now to prevent abuse and potential leakage of sensitive data to third-party app developers, Google has made several significant changes giving users more control over what type of data they choose to share with each app. The changes are part of Google's Project Strobe —a "root-and-branch" review of third-party developers access to Google account and Android device data and of its idea around apps' data access. Restricted Call Log and SMS Permissions for Apps Google announced some new changes to the way permissions are approved for Android apps to prevent abuse and potential leakage of sensitive call and text log data by third-party developers. While the apps are only supposed to request permission those are required for functioning properly, any Android app can ask permission to access y...

Facebook is set to launch an integrated email service on Monday, aiming to compete with Gmail and Yahoo Mail. This move will position Facebook as the largest email service provider in the world, serving its 500 million users. TechCrunch, a prominent Silicon Valley technology blog, reported that Facebook plans to announce a web-based email service featuring @facebook.com addresses at an event in San Francisco. This initiative, part of a secret project known as 'Project Titan,' is internally referred to as its 'Gmail killer.' Yahoo, Google, and Microsoft are already enhancing their email services to emphasize social connections. However, Facebook holds a significant advantage due to its extensive data on user relationships, making it easier to integrate email with its existing social services like photo-sharing. Facebook's new email service will seamlessly integrate with the social network, utilizing its network of friends model. The goal is to create a communic...
