![]() ![]() Figure 1 shows the Windows UI, Figure 2 shows the macOS UI, Figure 3 shows the iPhone, and Figure 4 shows the iPad. Wickr is available on Android, iOS, macOS, and Windows, and while these platforms are different, the Wickr user interface (UI) is relatively the same across these platforms. I can confirm that a backup nor a logical extraction contains the iOS Wickr database. For iOS devices, you will need a jailbroken phone or an extraction tool such as one that is metal, gray, and can unlock a door to get the Wickr database. For Android devices, the data resides in the /data/data area of the file system, so if your tool can get to this area, you should be able to get Wickr data. The user interface of Wickr Me is similar to the other versions, so the following sections will discuss the functionality of Wickr while using the personal version.įinally, how do you get the data? Logical extractions, at a minimum, should grab desktop platform Wickr data during an extraction. ![]() Third, Wickr Me contains the same encryption scheme and basic functionality as the Pro and Enterprise versions: encrypted messaging, encrypted file transfer, burn-on-read messages, audio calling, and secure “shredding” of data. IOS 12.4 iPhone XS and iPad Pro 10.5 5.22 Second, the devices and respective operating system versions/hardware are as follows: Because of some time constraints I did not have time to test this in Linux. First, this post encompasses Android, iOS, macOS, and Windows. Regardless, this app can bring the pain to examinations.īefore I get started, a few things to note. Personally, I am surpised it is not as popular as Signal, but I think not having Edward Snowden’s endorsement and initially being secretive about its protocal may have hurt Wickr’s uptake a bit. Wickr first hit the app market in 2012, and has been quietly hanging around since then. Initially available as an iOS-only app, Wickr expanded their app to include Android, Windows, macOS, and Linux, and branched out from personal messaging (Wickr Me) to small teams and businesses (Wickr Pro – similar to Slack), and an enterprise platform (Wickr Enterprise). For those that are unfamilar, Wickr is a company that makes a privacy-focused, ephemeral messaging application. One needs the latter mindset when it comes to Wickr. Do you let inaccessible data defeat you and you give up and quit, or do you carry on with that examination, getting what you can, and apply that same tenacity to future examinations? Keep in mind there is a larger fight, and how you react to this setback is a reflection of your dedication to our craft. Not being able to access such data is no judgment of your abilities, it just means you may not win this round. You can throw every tool known to civilization at it, try to manually examine it, phone a friend, look on Twitter, search the blog-o-sphere, search the Discord Channel, query a listserv, and conduct your own research and you still strike out. ![]() If you conduct digital forensic examinations for any substantial amount of time you are going to have examinations where there is inaccesible data and nothing you do is going to change that. ![]() I think there should be a similar mantra for digital forensic examiners. One of my mentors from my time investigating homicides told me early in my career that I was not doing it right unless I had some unsolved homicides on the books he felt it was some sort of badge of honor and showed a dedication to the craft. Its existence means there is a high probability there is data on a particular mobile device that I am not going to get access to, and this is usually after I have spent a considerable amount of time trying to gain access to the device itself. Not to pick on any particular tool vendor, but seeing this window (or one simmilar to it) brings a small bit of misery. I have been seeing the above pop-up window lately. I would like to thank Heather Mahalik and Or Begam, both of Cellebrite, who helped make the Android database portion of this blog post possible, and Mike Williamson of Magnet Forensics for all the help with the underpinnings of the iOS version.
