A critical flaw in Google's Dialogflow CX could have let an attacker with edit rights on one Code Block-enabled agent compromise other Code Block-enabled agents in the same Google Cloud project. From there, they could read live conversations, steal the data users shared, and make the bots send attacker-written messages, including requests to re-enter a password. Security firm Varonis found it and named it Rogue Agent. The flaw affected only organizations that built agents with Dialogflow's Playbooks and custom Code Blocks, which let developers add their own Python. And it was not a remote, unauthenticated attack. Pulling it off needed the dialogflow.playbooks.update permission on one such agent, which limits the realistic attacker to a malicious insider or a compromised developer account, not a stranger on the internet. From that one foothold, though, the reach extended to every agent in the project. Google has fixed it, and both Varonis and Google say there is no sig...

A Microsoft 365 device code phishing campaign has been observed leveraging collaboration-themed lures to take control of victim accounts between the last week of June 2026 and into early July, per findings from ZeroBEC. "The campaign did not depend on a fake Microsoft password page. It used a malicious collaboration-style lure to push users into the legitimate Microsoft device login experience, while a backend broker generated and polled Microsoft Authentication Broker device-code tokens," the email security company said in a report shared with The Hacker News. The activity is assessed to share "strong" overlaps with a campaign documented by Microsoft in February 2025 under the moniker Storm-2372 , including the use of messaging or Teams-style lures to trick unsuspecting victims into entering an attacker-provided device code, along with their credentials, effectively allowing the threat actor to recover the token and hijack their account. Despite these simi...

A public issue can trick GitHub Agentic Workflows into leaking the contents of an organization's private repositories, researchers at Noma Security have shown. The attacker needs only to open a normal-looking issue on a public repository, with no stolen credentials and no access to the organization. If that organization has given the agent read access across its repositories, private ones included, the issue can steer it into pulling private contents into a public comment. Noma calls the technique GitLost . The target is GitHub Agentic Workflows , a feature now in public preview that GitHub launched in February. Instead of writing automation scripts, you write instructions to an AI agent in plain English in a Markdown file. The agent reads issues and pull requests, runs tools, and replies on its own. It can be powered by GitHub Copilot, Anthropic's Claude, Google Gemini, or OpenAI Codex. Workflows are read-only by default, but an organization can hand one a token with...

U.S. prosecutors linked an alleged Scattered Spider hacker to a break-in at a luxury jewelry retailer using a persistent Windows device ID, according to a newly unsealed federal complaint . Microsoft records tied that ID first to the account the attackers used to keep access during the May 2025 intrusion, then to online accounts prosecutors say belong to 19-year-old Peter Stokes. Stokes is charged with conspiracy, computer intrusion, and fraud. A dual U.S.-Estonian citizen known online as "Bouquet," he was extradited from Finland and made his first court appearance in Chicago on June 30, as THN reported . He is presumed innocent pending trial. How the break-in worked Between May 12 and 15, 2025, attackers phoned the retailer's IT help desk from Google Voice numbers, posed as locked-out employees, and got staff to reset employees' passwords and the mobile devices tied to their multifactor authentication. Within a few hours, they controlled three accounts, t...

Cybersecurity researchers have disclosed details of a now-patched critical session isolation vulnerability in Writer , an enterprise generative artificial intelligence (AI) platform, that could result in cross-tenant compromise. The one-click vulnerability has been codenamed WriteOut by the Sand Security Research team. "An outsider could go from having no access to taking over any Writer AI organization inside industry-leading enterprises, with nothing more than a link," the cybersecurity company said in a report shared with The Hacker News. Put differently, the shortcoming could be abused to take over a victim's Writer account, and use it to access private chats, documents, and other sensitive data related to agents, configurations, private models, connectors, and large language model (LLM) credentials. Even worse, it could be abused to seize administrative control depending on the victim's role. An important aspect of the flaw is that the attacker and the...
