The boom in personal electronic devices recording literally every persons’ step introduced a new type of forensic evidence: the digital evidence. In this day and age, significantly more forensic evidence is available in digital form compared to physical evidence of yesteryear. Are law enforcement and intelligence agencies ready to handle the abundance of digital evidence? And more importantly, do frontline officers have the skills and technical expertise required to handle and preserve this wealth of information?

Health data is among the most important bits of information about a person. Health information is just as sensitive as the person’s passwords – and might be even more sensitive. It is only natural that health information is treated accordingly. Medical facilities are strictly regulated and take every possible security measure to restrict access to your medical records.

Heartrate, sleeping habits, workouts, steps and walking routines are just a few things that come to mind when we speak of Apple Health. Introduced in September 2014 with iOS 8, the Apple Health app is pre-installed on all iPhones. The app makes use of low-energy sensors, constantly collecting information about the user’s physical activities. With optional extra hardware (e.g. Apple Watch), Apple Health can collect significantly more information. In this article we’ll talk about the types of evidence collected by Apple Health, how they are stored and how to extract the data. (more…)

In today’s usage scenarios, messaging are not entirely about the text. Users exchange pictures and short videos, voice recordings and their current locations. These types of data are an important part of conversation histories; they can be just as valuable evidence as the text content of the chat.

iMessage is undoubtedly one of the most popular instant messaging platforms for an obvious reason: it’s built in to iOS and ships with every iPhone by default. iMessage does not require complex setup, so the number of iMessage users is closely matching the number of iPhone users. Apple sells about 200 million iPhones every year, and the total number of iPhones sold is more than a billion. Unless you absolutely must chat with someone outside of Apple’s ecosystem (like those poor Android folks), you won’t need Skype, WhatsApp or Telegram. It’s also comforting to know that iMessage works everywhere around the world while most other messengers are oppressed in one or more countries.

The iPhone Xs employs a revised version of the OLED panel we’ve seen in last year’s iPhone X. The iPhone Xs Max uses a larger, higher-resolution version of the panel. Both panels feature higher peak brightness compared to the OLED panel Apple used in the iPhone X. While OLED displays are thinner and more power-efficient compared to their IPS counterparts, most OLED displays (including those installed in the iPhone Xs and Xs max) will flicker at lower brightness levels. The screen flickering is particularly visible in low ambient brightness conditions, and may cause eyestrain with sensitive users. The OLED flickering issue is still mostly unheard of by most consumers. In this article we will demystify OLED display flickering and provide a step by step instruction on how to conveniently disable (and re-enable) PWM flickering on iPhone Xs and Xs Max displays to reduce eyestrain.

Working in a mobile forensic company developing tools for iCloud forensics, logical and physical extraction of iPhone devices, we don’t live another day without being asked if (or “how”) we can help remove iCloud lock from a given iPhone. Without throwing a definite “yes” or “no” (or “just buy this tool”), we’ve decided to gather everything we know about bypassing, resetting and disabling iCloud activation lock on recent Apple devices.

Cloud analysis is arguably the future of mobile forensics. Whether or not the device is working or physically accessible, cloud extraction often allows accessing amounts of information far exceeding those available in the device itself.

With more than 127 million users in multiple countries, Apple Pay is one of the more popular contactless payment systems. Unlike some competing payment technologies, Apple Pay is not only tightly integrated into Apple’s ecosystem but is exclusive to Apple devices.

The release of iOS 11.4.1 marked the introduction of USB restricted mode, a then-new protection scheme disabling USB data pins after one hour. The USB restricted mode was not invincible; in fact, one could circumvent protection by connecting the device to a $39 accessory. While a great improvement on itself, the new mode did not provide sufficient protection. We wished Apple maintained a list of “trusted” or previously connected accessories on the device, allowing only such devices to reset the timer. In this new iOS 12 beta, Apple makes attempts to further “improve” USB restricted mode, yet the quotes about “improving” the system are there on purpose.
