Israeli entities spanning academia, engineering, local government, manufacturing, technology, transportation, and utilities sectors have emerged as the target of a new set of attacks undertaken by Iranian nation-state actors that have delivered a previously undocumented backdoor called MuddyViper. The activity has been attributed by ESET to a hacking group known as MuddyWater (aka Mango

### Impact Attackers can delete any file on the server at will, causing damage or unavailability of server resources. Attackers can control the 'FileMd5' parameter to delete any file and folder The affected code:  Affected interfaces: /api/fileUploadAndDownload/removeChunk POC: You can specify the FileMd5 value as the directory or file you want to delete ```POST /api/fileUploadAndDownload/removeChunk HTTP/1.1 Host: 127.0.0.1:8080 Content-Length: 78 sec-ch-ua: "Not=A?Brand";v="99", "Chromium";v="118" x-token: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJVVUlEIjoiOGYzYTdjMmMtYjAwMC00ODFmLWEyNGYtYzQyMDc2NTFjNWRmIiwiSUQiOjEsIlVzZXJuYW1lIjoiYWRtaW4iLCJOaWNrTmFtZSI6Ik1yLuWlh-a3vCIsIkF1dGhvcml0eUlkIjo4ODgsIkJ1ZmZlclRpbWUiOjg2NDAwLCJpc3MiOiJxbVBsdXMiLCJhdWQiOlsiR1ZBIl0sImV4cCI6MTc2MzIxNDQzMywibmJmIjoxNzYyNjA5NjMzfQ.7BTnRq65JDiPdlb0gJuAUa2nifIDTtePsnDnAtZoFJQ sec-ch-ua-mobile: ?0 User-Agent: Mozilla/5....

## Summary Keras's `keras.utils.get_file()` function is vulnerable to directory traversal attacks despite implementing `filter_safe_paths()`. The vulnerability exists because `extract_archive()` uses Python's `tarfile.extractall()` method without the security-critical `filter="data"` parameter. A PATH_MAX symlink resolution bug occurs before path filtering, allowing malicious tar archives to bypass security checks and write files outside the intended extraction directory. ## Details ### Root Cause Analysis **Current Keras Implementation** ```python # From keras/src/utils/file_utils.py#L121 if zipfile.is_zipfile(file_path): # Zip archive. archive.extractall(path) else: # Tar archive, perhaps unsafe. Filter paths. archive.extractall(path, members=filter_safe_paths(archive)) ``` ### The Critical Flaw While Keras attempts to filter unsafe paths using `filter_safe_paths()`, this filtering happens after the tar archive members are parsed and before actual extraction. Ho...

### Summary The `MCPScanner ` class contains a critical Command Injection vulnerability in the `cloneRepo `method. The application passes the user-supplied githubUrl argument directly to a system shell via execSync without sanitization. This allows an attacker to execute arbitrary commands on the host machine by appending shell metacharacters to the URL. ### Details The vulnerability exists in the src/scanner/MCPScanner.ts file within the cloneRepo method. [https://github.com/kapilduraphe/mcp-watch/blob/0fca7228bd313ae5aa938d61311377e88ce6e682/src/scanner/McpScanner.ts#L181](https://github.com/kapilduraphe/mcp-watch/blob/0fca7228bd313ae5aa938d61311377e88ce6e682/src/scanner/McpScanner.ts#L181) The code uses child_process.execSync to execute a git clone command: Because execSync spawns a shell (defaulting to `/bin/sh` on Unix or` cmd.exe` on Windows), any shell metacharacters present in the url argument will be interpreted by the shell. The application does not validate that the url ...

Werkzeug's `safe_join` function allows path segments with Windows device names. On Windows, there are special device names such as `CON`, `AUX`, etc that are implicitly present and readable in every directory. `send_from_directory` uses `safe_join` to safely serve files at user-specified paths under a directory. If the application is running on Windows, and the requested path ends with a special device name, the file will be opened successfully, but reading will hang indefinitely.

Hackers aren’t kicking down the door anymore. They just use the same tools we use every day — code packages, cloud accounts, email, chat, phones, and “trusted” partners — and turn them against us. One bad download can leak your keys. One weak vendor can expose many customers at once. One guest invite, one link on a phone, one bug in a common tool, and suddenly your mail, chats, repos, and

The threat actor known as Tomiris has been attributed to attacks targeting foreign ministries, intergovernmental organizations, and government entities in Russia with an aim to establish remote access and deploy additional tools. "These attacks highlight a notable shift in Tomiris's tactics, namely the increased use of implants that leverage public services (e.g., Telegram and Discord) as

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has updated its Known Exploited Vulnerabilities (KEV) catalog to include a security flaw impacting OpenPLC ScadaBR, citing evidence of active exploitation. The vulnerability in question is CVE-2021-26829 (CVSS score: 5.4), a cross-site scripting (XSS) flaw that affects Windows and Linux versions of the software via

Practicing good “operations security” is essential to staying safe online. Here's a complete guide for teenagers (and anyone else) who wants to button up their digital lives.
