Samsung Factory Reset Protection (FRP) Bypass
What does it do?
Samsung’s Factory Reset Protection (FRP) is a feature that allows users to prevent stolen devices that they own from being used by others after a factory reset. It’s a key feature that can help reduce the frequency of stolen phones on the market.
This bypass allows an assailant to use the Secure Folder feature to prevent FRP from communicating with the remainder of the device. The process is simple enough to perform that there are even several online tutorials on the topic.
Potential Impact
Though personal data does seem to be secure, the problem with this threat is the ease of use and loss of property. It can cause certain models to gain demand due to their newfound appreciation on the black market and make theft more of a problem to businesses.
Remediation
A patch has been released by Samsung and has been pushed in latest updates.

Android RCE
What does it do?
In the Android security bulletin released near the beginning of November, a patch was announced that fixed a series of severe security flaws. The most severe flaw announced was a proximity-based flaw that could allow attackers to execute arbitrary code as a privileged process.
Using exif_entry_get and exif-entry.c, attackers could cause an integer overflow if a third party application used the libraries to process remote image data. The most significant thing of note here is that this does not require any form of user interaction to pull off.
Potential Impact
Any form of remote code execution flaw means a significant reduction in security through the entirety of the CIA triad, it all depends on what form of code execution is chosen and available to the attacker. It is for this reason that impact from these vulnerabilities is set so high. Remediation: A patch has been released by Android. Please ensure that you or the mobile device manager for your business installs this update. More Information: CVE-2020-0452

Additional Threats
CVE-2020-28864
Buffer overflow in WinSCP 5.17.8 allows a malicious FTP server to cause a denial of service or possibly have other unspecified impact via a long file name.
More InfoCVE-2020-3531
A vulnerability in the REST API of Cisco IoT Field Network Director (FND) could allow an unauthenticated,
remote attacker to access the back-end database of an affected system.
The vulnerability exists because the affected software does not properly authenticate REST API calls. An attacker could exploit this vulnerability by obtaining a cross-site request forgery (CSRF) token and then using the token with REST API requests. A successful exploit could allow the attacker to access the back-end database of the affected device and read, alter, or drop information.
CVE-2020-15993
Use after free in printing in Google Chrome prior to 86.0.4240.99 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

Customer Use Case
Automated Salesforce Monitoring
Summary
Salesforce users used to be manually added to lists, looked up via search engines, and their activity had to be verified through a series of different methods. Though effective, this process took far more time than desired and caused a greater chance for error. User managers had to be contacted regularly to confirm the presence of a user.
Automated Solution
Through automated commands and custom integrations like Cisco Talos integration, cases now arrive with all information on the user previously seen in logs available to the investigator. The creation of the account, prior activity, IP rating, any existing social media, and the user’s full name become easy to access and useful for triage. In some instances, the case can be automatically resolved.
Benefits to This Approach
- Quick access to information
- Consistent in sourcing and data
- Automated resolution
- Information consolidated for reporting
- Methods of lookup are documented within the automated monitoring process
