hacking: security in practice
I once met a professional hacker on here but lost contact with him...

He was depressed and posted on a subreddit about why he was depressed and wanted dating advice. I gave him my advice and he really like it. So, we struck up a conversation and I was really curious about his hacker world. He said as a rule, he doesn't share content of celebrities. I put him to the test, I had a long lost beau and shared a photo. He not only found him to shared that he was married and divorced. He gave me my old beau's address and I got to reconnect with him. I lost contact with my hacker friend. I hope he is doing well.

De-indexing a page

Is it possible to hire someone to de-index a news page about you?

Unfortunately the local news paper will not answer my requests and this is destroying my life. I lost two jobs and spent thousands of dollars trying to push it down.

Critical RCE Vulnerability Found in vm2 Sandbox Library

Critical RCE Vulnerability Found in vm2 Sandbox LibraryPost Views: 1 Premium Contenthttps://www.blackhatethicalhacking.com/wp-content/uploads/2022/09/Patreon.png Subscribe to Patreon to watch this episode.
Reading Time: 3 Minutes Researchers are warning of a critical remote code execution flaw in ‘vm2’, a JavaScript sandbox library downloaded over 16 million times per month via the NPM package repository.The vm2 vulnerability is tracked as CVE-2022-36067 and received a severity rating of 10.0, the maximum score in the CVSS system, as it could allow attackers to escape the sandbox environment and run commands on a host system.

Sandboxes are meant to be an isolated environment that is walled off from the rest of the operating system. However, as developers commonly use sandboxes to run or test potentially unsafe code, the ability to “escape” from this confined environment and execute code on the host is a massive security problem.
See Also: So you want to be a hacker? Complete Offensive Security and Ethical Hacking Course Escaping the sandboxSecurity researchers at Oxeye have found a clever way to customize the call stack of an error that occurs in VM2 to generate “CallSite” objects created outside the sandbox and use them to access Node’s global objects and execute commands.

While the library’s authors attempted to mitigate this possibility in the past, Oxeye’s researchers found a way to bypass this mitigation mechanism by using a custom implementation of the “prepareStackTrace” method.

“The reporter’s POC bypassed the logic above since vm2 missed wrapping specific methods related to the “WeakMap” JavaScript built-in type,” the researchers explain in their report.

“This allowed the attacker to provide their own implementation of “prepareStackTrace,” then trigger an error, and escape the sandbox.”

Update as soon as possibleOxeye’s research team discovered this critical problem on August 16, 2022, and reported it to the VM2 team a couple of days later, who confirmed they had launched an investigation.

Eventually, the authors of the popular library released version 3.9.11 on August 28, 2022, which addressed the sandbox escape and code execution problems.

Software developers are urged to update to the latest VM2 version and replace older releases in their projects as soon as possible.

For end users, it is important to note that it could take a while before virtualization software tools relying on VM2 apply the available security update.

As we saw with Log4Shell, a critical security problem in a widely deployed open-source library may persist for extended periods without the impacted users even knowing they’re vulnerable due to the obscurity in the supply chain.

If you use a sandbox solution, check if it relies on VM2 and whether it’s using the latest version.
