North Korea’s Lazarus Group deploys a new BeaverTail variant to steal credentials and crypto using fake job lures, dev tools, and smart contracts.

## Summary S3 Encryption Client for Java is an open-source client-side encryption library used to facilitate writing and reading encrypted records to S3. When the encrypted data key (EDK) is stored in an "Instruction File" instead of S3's metadata record, the EDK is exposed to an "Invisible Salamanders" attack (https://eprint.iacr.org/2019/016), which could allow the EDK to be replaced with a new key. ## Impact ### Background - Key Commitment There is a cryptographic property whereby under certain conditions, a single ciphertext could be decrypted into 2 different plaintexts by using different encryption keys. To address this issue, strong encryption schemes use what is known as "key commitment", a process by which an encrypted message can only be decrypted by one key; the key used to originally encrypt the message. In older versions of S3EC, when customers are also using a feature called "Instruction File" to store EDKs, key commitment is not implemented because multiple E...

Cisco Talos’ Vulnerability Discovery & Research team recently disclosed vulnerabilities in Biosig Project Libbiosig, Grassroot DiCoM, and Smallstep step-ca. The vulnerabilities mentioned in this blog post have been patched by their respective vendors, all in adherence to Cisco’s third-party vulnerability disclosure policy, except for Grassroot, as the

In jose4j before 0.9.5, an attacker can cause a Denial-of-Service (DoS) condition by crafting a malicious JSON Web Encryption (JWE) token with an exceptionally high compression ratio. When this token is processed by the server, it results in significant memory allocation and processing time during decompression.

Google's patched two flaws in Chrome, both of which can be triggered remotely when a user loads specially crafted web content.

Researchers at Point Wild have discovered a new ClickFix attack campaign that tricks users into manually installing DarkGate malware via fake browser extension alerts. Learn how this attack bypasses security by using the Windows Run box and how you can stay safe.

A “purchase order” PDF blocked by Malwarebytes led to a credential-harvesting phishing site. So we analyzed the attack and where the data went next.

A new campaign named GhostPoster has leveraged logo files associated with 17 Mozilla Firefox browser add-ons to embed malicious JavaScript code designed to hijack affiliate links, inject tracking code, and commit click and ad fraud. The extensions have been collectively downloaded over 50,000 times, according to Koi Security, which discovered the campaign. The add-ons are no longer available.

## Summary The `fsSize()` function in `systeminformation` is vulnerable to **OS Command Injection (CWE-78)** on Windows systems. The optional `drive` parameter is directly concatenated into a PowerShell command without sanitization, allowing arbitrary command execution when user-controlled input reaches this function. **Affected Platforms:** Windows only **CVSS Breakdown:** - **Attack Vector (AV:N):** Network - if used in a web application/API - **Attack Complexity (AC:H):** High - requires application to pass user input to `fsSize()` - **Privileges Required (PR:N):** None - no authentication required at library level - **User Interaction (UI:N):** None - **Scope (S:U):** Unchanged - executes within Node.js process context - **Confidentiality/Integrity/Availability (C:H/I:H/A:H):** High impact if exploited > **Note:** The actual exploitability depends on how applications use this function. If an application does not pass user-controlled input to `fsSize()`, it is not vulnerable. ...

## Summary The `/__vite_rsc_findSourceMapURL` endpoint in `@vitejs/plugin-rsc` allows **unauthenticated arbitrary file read** during development mode. An attacker can read any file accessible to the Node.js process by sending a crafted HTTP request with a `file://` URL in the `filename` query parameter. **Severity:** High **Attack Vector:** Network **Privileges Required:** None **Scope:** Development mode only (`vite dev`) --- ## Impact ### Who Is Affected? - **All developers** using `@vitejs/plugin-rsc` during development - Projects running `vite dev` with the RSC plugin enabled ### Attack Scenarios 1. **Network-Exposed Dev Servers:** When developers run `vite --host 0.0.0.0` (common for mobile testing), attackers on the same network can read files. 2. ~**XSS-Based Attacks:**~ ~If the application has an XSS vulnerability, malicious JavaScript can fetch sensitive files and exfiltrate them.~ 3. ~**Malicious Dependencies:** ~ ~A compromised npm package could incl...
