FortiGuard Labs reveals Chaos-C++, a new Chaos ransomware variant that deletes files over 1.3 GB instead of encrypting them and uses clipboard hijacking to steal cryptocurrency.

Token theft is a leading cause of SaaS breaches. Discover why OAuth and API tokens are often overlooked and how security teams can strengthen token hygiene to prevent attacks. Most companies in 2025 rely on a whole range of software-as-a-service (SaaS) applications to run their operations. However, the security of these applications depends on small pieces of data called tokens. Tokens, like

Cisco Talos has confirmed that ransomware operators are leveraging Velociraptor, an open-source digital forensics and incident response (DFIR) tool that had not previously been definitively tied to ransomware incidents.   We assess with moderate confidence that this activity can be attributed to threat actor Storm-2603, based on overlapping tools

Russian hackers' adoption of artificial intelligence (AI) in cyber attacks against Ukraine has reached a new level in the first half of 2025 (H1 2025), the country's State Service for Special Communications and Information Protection (SSSCIP) said. "Hackers now employ it not only to generate phishing messages, but some of the malware samples we have analyzed show clear signs of being generated

Threat actors are actively exploiting a critical security flaw impacting the Service Finder WordPress theme that makes it possible to gain unauthorized access to any account, including administrators, and take control of susceptible sites. The authentication bypass vulnerability, tracked as CVE-2025-5947 (CVSS score: 9.8), affects the Service Finder Bookings, a WordPress plugin bundled with the

A flaw was found in org.keycloak/keycloak-model-storage-service. The `KeycloakRealmImport` custom resource substitutes placeholders within imported realm documents, potentially referencing environment variables. This substitution process allows for injection attacks when crafted realm documents are processed. An attacker can leverage this to inject malicious content during the realm import procedure. This can lead to unintended consequences within the Keycloak environment.

Prior to Opencast 17.8 and 18.2 the paella would include and render some user inputs (metadata like title, description, etc.) unfiltered and unmodified. ### Impact The vulnerability allows attackers to inject and malicious HTML and JavaScript in the player, which would then be executed in the browsers of users watching the prepared media. This can then be used to modify the site or to execute actions in the name of logged-in users. To inject malicious metadata, an attacker needs write access to the system. For example, the ability to upload media and modify metadata. This cannot be exploited by unauthenticated users. ### Patches This issue is fixed in Opencast 17.8 and 18.2, however they are not published to the Maven registry. ### Resources - [Patch fixing the issue](https://github.com/opencast/opencast/commit/2809520fa88d108d8104c760f00c10bad42c14f9) ### For more information If you have any questions or comments about this advisory: * Open an issue in [our issue tracker](htt...

### Summary A file upload vulnerability in FlowiseAI allows authenticated users to upload arbitrary files without proper validation. This enables attackers to persistently store malicious Node.js web shells on the server, potentially leading to Remote Code Execution (RCE). ### Details The system fails to validate file extensions, MIME types, or file content during uploads. As a result, malicious scripts such as Node.js-based web shells can be uploaded and stored persistently on the server. These shells expose HTTP endpoints capable of executing arbitrary commands if triggered. The uploaded shell does not automatically execute, but its presence allows future exploitation via administrator error or chained vulnerabilities. #### Taint Flow - **Taint 01: Route Registration** `POST` file requests are routed to the controller via Multer https://github.com/FlowiseAI/Flowise/blob/d29db16bfcf9a4be8febc3d19d52263e8c3d0055/packages/server/src/routes/attachments/index.ts#L8 - **Taint ...

### Impact Lack of validation for device keys in Synapse before 1.138.3 and in Synapse 1.139.0 allow an attacker registered on the victim homeserver to degrade federation functionality, unpredictably breaking outbound federation to other homeservers. ### Patches Patched in Synapse 1.138.3, 1.138.4, 1.139.1, and 1.139.2. Note that even though 1.138.3 and 1.139.1 fix the vulnerability, they inadvertently introduced an unrelated regression. For this reason, it is recommend to skip these releases and upgrading straight to 1.138.4 and 1.139.2. ### Workarounds The vulnerability can only be exploited by users registered on the victim homeserver.

Multiple cross-site scripting (XSS) vulnerabilities in the Notifications widget in Liferay Portal 7.4.3.102 through 7.4.3.111, and Liferay DXP 2023.Q4.0 through 2023.Q4.5 and 2023.Q3.1 through 2023.Q3.10 allow remote attackers to inject arbitrary web script or HTML via a crafted payload injected into (1) a user’s “First Name” text field, (2) a user’s “Middle Name” text field, (3) a user’s “Last Name” text field, (4) the “Other Reason” text field when flagging content, or (5) the name of the flagged content.
