![]() For SPS packages, we go even further by code sign ing the package. QualityĪ lot of time is invested in researching the silent command line parameters for each patch. All the silent command lines go through an internal QA cycle to ensure the installation performs as expected. For SPS Packages, the silent command line parameters are wrapped within the installer file, however, for Vendor Patch Module the silent command line parameters are provided external to the installer file.Įach is installed with re searched silent command line parameter s to verify a successful, silent installation. There is always some level of risk involved in deploying patches, so it is important to test and ensure expected behavior in your unique environment.įor SPS packages additional proactive testing is done by deploying the packages in the live environment on various versions of Windows to ensure the package behavior is as expected. Download an Android emulator for PC and Mac.However, you can rest assured that Flexera has employed a robust process to ensure confidence that any patch from Flexera has undergone strict scrutiny in terms of security, integrity, and quality to help you deploy the patches with full confidence. We recommend Bluestacks because you can easily find solutions online if you run into problems while using it. Install the emulator on your PC or Mac.Download Bluestacks Pc or Mac software Here >. Once Integrity Plus is downloaded inside the emulator, locate/click the "All apps" icon to access a page containing all your installed applications including Integrity Plus.The search will reveal the Integrity Plus app icon.Open the Emulator app you installed » goto its search bar and search "Integrity Plus".On your computer, goto the Downloads folder » click to install Bluestacks.exe or Nox.exe » Accept the License Agreements » Follow the on-screen prompts to complete installation. A modified User Interface (as found in ) will also display a warning message on boot.Install Integrity Plus on your Mac using the same steps for Windows OS above. When opening an application, a Non Genuine warning is displayed if it is not signed by Ledger. You can verify it by running: pip install -no-cache-dir ledgerblue python -m ledgerblue.checkGenuineRemote -targetId 0x33000004 The Secure Element itself is personalized at factory with an attestation proving that it has been created by us. (Back of the PCB) Secure Element attestation As an additional check, you can open the device to verify that no additional chip has been added, compared with the images below, and that the MCU is an STM32F042K6U6. ![]() If it has been modified, you'll get a warning at boot. ![]() The Secure Element checks the full microcontroller flash at boot, as described in this blog post. A modified User Interface (as found in ) will also display a warning message on boot. Python -m ledgerblue.checkGenuineRemote -targetId 0x33000004 You can verify it by running pip install -no-cache-dir ledgerblue Markings on the chip can vary but you should see the string "042K6". As an additional check, you can open the device to verify that no additional chip has been added (referring to the attached picture) and that the MCU is an stm2f042k6 (with 32 Kb flash, as a bigger flash could contain code fooling the Secure Element validation). When opening an application, a Non Genuine warning is displayed if the app has not been signed by Ledger.
