hacking: security in practice
does art imitate life? how accurate are the movies?

Im sorry if this is a dumb question as I'm completely illiterate when it comes to hacking heck even most computer stuff but I am morbidly curious...Do the movies and common depictions of hacking reflect somewhat what hacking actually is?

Like is it theoretically possible to remotely access anything, from smartphones, laptops, emails, all from the convenience of a coffee shop or your neighbors wifi?

I'm asking if after years of training and dedication could you have this superpower of getting a front row seat to everyone personal data and private lives. Like being able to know people without even having to meet them. That sounds insane.

Windows IKE RCE : Researcher releases PoC code for Windows IKE RCE (CVE-2022-34721)

Windows IKE RCE is a critical Windows Internet Key Exchange (IKE) Protocol Extensions Remote Code Execution vulnerability impacting numerous Windows versions, according to a security researcher from the Cyber Security Research Company, 78researchlab. Internet Key Exchange is the mechanism used to create a security association (SA) in the IPsec protocol family, according to Wikipedia. The Oakley protocol and ISAKMP are built upon by IKE. IKE establishes a shared session secret from which cryptographic keys are produced using X.509 certificates for authentication, either pre-shared or distributed using DNS (ideally with DNSSEC).

Microsoft urged users to promptly install fixes since it has issued a warning that a threat actor might use the vulnerability (CVSSv3 base score of 9.8) to execute arbitrary code on the machine. Yuki Chen, who discovered the flaw in Cyber KunLun, was thanked by the company.
This vulnerability allows an attacker to run arbitrary code on the system by delivering a specially crafted IP packet to a Windows node with IPSec enabled. IKEv1 alone is affected by CVE-2022-34721. However, because they accept both V1 and V2 packets, all Windows Servers are impacted. Microsoft patched the flaw on September’s Patch Tuesday.

Today, 78ResearchLab made the proof-of-concept code for this vulnerability available on GitHub, and it will soon publish the analysis report. Users of vulnerable Windows versions are advised to prioritise installing the fixes in order to stop ongoing exploitation efforts in light of the PoC’s release.

Microsoft Teams stores auth tokens as cleartext in Windows, Linux, Macs

Microsoft Teams stores auth tokens as cleartext in Windows, Linux, MacsPost Views: 173 Premium Contenthttps://www.blackhatethicalhacking.com/wp-content/uploads/2022/08/Patreon-1.png Subscribe to Patreon to watch this episode.
Reading Time: 3 Minutes Security analysts have found a severe security vulnerability in the desktop app for Microsoft Teams that gives threat actors access to authentication tokens and accounts with multi-factor authentication (MFA) turned on.Microsoft Teams is a communication platform, included in the 365 product family, used by more than 270 million people for exchanging text messages, videoconferencing, and storing files.

The newly discovered security issue impacts versions of the application for Windows, Linux, and Mac and refers to Microsoft Teams storing user authentication tokens in clear text without protecting access to them.

An attacker with local access on a system where Microsoft Teams is installed could steal the tokens and use them to log into the victim’s account.

“This attack does not require special permissions or advanced malware to get away with major internal damage,” Connor Peoples at cybersecurity company Vectra explains in a report this week.

The researcher adds that by taking “control of critical seats–like a company’s Head of Engineering, CEO, or CFO—attackers can convince users to perform tasks damaging to the organization.”

Vectra researchers discovered the problem in August 2022 and reported it to Microsoft. However, Microsoft did not agree on the severity of the issue and said that it doesn’t meet the criteria for patching.

Electron does not support encryption or protected file locations by default, so while the software framework is versatile and easy to use, it is not considered secure enough for developing mission-critical products unless extensive customization and additional work is applied.

Vectra analyzed Microsoft Teams while trying to find a way to remove deactivated accounts from client apps, and found an ldb file with access tokens in clear text.
“Upon review, it was determined that these access tokens were active and not an accidental dump of a previous error. These access tokens gave us access to the Outlook and Skype APIs.” – Vectra
Additionally, the analysts discovered that the “Cookies” folder also contained valid authentication tokens, along with account information, session data, and marketing tags.

doing this for other applications, such as Google Chrome, Microsoft Edge, Mozilla Firefox, Discord, and many more.
Trending: Security Engineer vs. Software Engineer
Trending: Recon Tool: ZenBuster Risk mitigationWith a patch unlikely to be released, Vectra’s recommendation is for users to switch to the browser version of the Microsoft Teams client. By using Microsoft Edge to load the app, users benefit from additional protections against token leaks.

The researchers advise Linux users to move to a different collaboaration suite, especially since Microsoft announced plans to stop supporting the app for the platform by December.

For those that can’t move to a different solution immediately, they can create a monitoring rule to discover processes accessing the following directories:

* [Windows] %AppData%\Microsoft\Teams\Cookies
* [Windows] %AppData%\Microsoft\Teams\Local Storage\leveldb
* [macOS] ~/Library/Application Support/Microsoft/Teams/Cookies
* [macOS] ~/Library/Application Support/Microsoft/Teams/Local Storage/leveldb
* [Linux] ~/.config/Microsoft/Microsoft Teams/Cookies
* [Linux] ~/.config/Microsoft/Microsoft Teams/Local Storage/leveldb

BleepingComputer has contacted Microsoft about the company’s plans to release a fix for the issue and will update the article when we get an answer.

Update 9/14/22 – A Microsoft spokesperson sent us the following comment regarding Vectra’s findings:

The technique described does not meet our bar for immediate servicing as it requires an attacker to first gain access to a target network.

We appreciate Vectra Protect’s partnership in identifying and responsibly disclosing this issue and will consider addressing in a future product release. ​Trending: GIFShell attack creates reverse shell using Microsoft Teams GIFs
