Hidden apps are growing in popularity. While initially marketed as a way for teens to hide videos, photos, forbidden apps, and text messages from the watchful eyes of parents, the use of hidden apps is quickly expanding. Hidden apps are increasingly used for criminal activity. At the local level, they can be used as a tool to facilitate drug transactions, sexual assaults, child-porn, as well as data exfiltration and theft. On a much larger and more dangerous international scale, these apps can be used for recruitment purposes by ISIS and other terrorist groups.
Because hidden apps are becoming more common sources of evidentiary data in criminal cases, it is essential that forensic investigators take the time to learn about them. Otherwise, key evidence could be missed. When it comes to hidden apps, awareness is critical. Forensic examiners must know these apps exist and how to find them.
While there are many hidden apps on the market today, new ones are introduced virtually every day. A quick Internet search is an excellent way to stay current on what’s available and trending in the world of hidden apps. Along with knowledge of what’s out there, examiners must know how apps and data are being hidden to ensure they are not overlooked.
Types of Hidden Apps There are three main ways to hide apps. Some users manipulate their phones to hide things in places where they don’t belong. Others use apps that are designed to hide other apps inside. Then there are “official” hidden apps (also known as decoy apps), which appear to do one thing while they are actually designed to do something else. One of the most popular hidden apps is the calculator app.
These apps are fully functioning calculators with a twist. Once a password is entered, a new interface appears that allows users to access and store pictures, videos, documents or files that are otherwise hidden to someone reviewing data on the phone.
A less technical, but commonly seen way to hide apps is for the user to create folders or nests of folders on their phone that appear to be harmless, and then to store data they wish to hide within that folder. They may even install an application that allows them to change an app’s icon so that it appears to be a different app on the phone.
Hidden apps reinforce a valuable lesson in the world of forensics, just because you don’t see something initially, doesn’t mean nothing is there. While it is not realistic to expect examiners to stay current on each and every app, knowing they exist and might be installed is essential. During an investigation it is wise to consider a hidden app might be in use, which means a deeper dive is necessary.
Efforts are underway to track down the international syndicates involved in the rhino horn trade, thanks to a new DNA system.
This meant a rhino horn confiscated in Vietnam could be linked back to a crime scene in the Kruger National Park.
“With this it will be possible to identify smuggling routes and more role players than just the poachers,” says Dr Cindy Harper, developer of RhODIS Rhino DNA system. She is also a director at the University of Pretoria’s veterinary genetics laboratory at Onderstepoort.
DNA profiling would help law enforcement agencies find the trafficking route, the couriers, kingpins, and end users. One prosecutor dealing with rhino horn poaching cases welcomed the development.
“The kingpin and the mastermind are the ones we should be prosecuting, and with RhODIS becoming available to international forensic scientists and investigators, we are getting closer,” Ansie Venter said.
"We might soon be able to connect a horn in Vietnam to a poached rhino in the Kruger National Park. What an immense breakthrough.”
Harper said it was introduced in 2010. The database contained information about more than 20 000 individual rhino. Countries using the system included Namibia, Kenya, Zimbabwe, Malawi, Uganda, Zambia, and Botswana.
At a RhODIS Scientific Workshop held in the Kruger National Park recently, it was agreed that the system would form the basis for the international DNA testing of rhino and rhino products. DNA forensic scientists, law enforcement officers and investigators from countries including Malaysia, Thailand, Vietnam, and India attended the workshop.
They were taken to a poaching crime scene in the park, allowing them to see first-hand the savagery inflicted on two rhino killed for their horns. Scientists participated in DNA sample collection training at the crime scene using the forensic sample kits developed for RhODIS. SANParks spokesperson Isaac Phaahla said they supported the collection of DNA as it was part of the criminal investigation.
“We think our colleagues in the NGO sector concentrating on user markets are doing a sterling job,” he said.
The news that convicted murderer Colin Pitchfork was denied parole was shocking. Not that he was denied, but that he was still alive. Certainly, the first case in history that utilized DNA evidence in a forensic context had to be a very long time ago. In truth, Pitchfork was put away 28 years ago. Back then, there wasn’t a single offender DNA database in the world. Now, they are standard in over 50 countries and expanding almost on a daily basis. We’ve gone through RFLP, Castro and the admissibility wars, Budowle and Lander and Nature Magazine , NRC I (and II), Dotson and Bloodsworth, and Simpson. We are even looking at the reality of performing DNA analysis in 90 minutes in police stations. DNA databases have been used to help convict Lonnie Franklin Jr., known as the Grim Sleeper, using familial testing, and have also been used to exonerate 300 innocent people and counting in the US alone.
On this odd recognition of the Pitchfork conviction, it’s important to realize that the changes brought about by the integration of DNA technology into the world’s criminal justice systems have been systemic. Statutes of limitations have been altered and even eliminated to allow for more exonerations and to crack cold cases. The passage of legislation to create DNA databases has created one of our more effective crime fighting tools. But, the broadest impact of DNA technology has been conceptual.
What started as a better piece of evidence has become a better understanding of the weaknesses in our system. Our concepts of quality forensic science, reliable evidence and trustworthy convictions have changed dramatically. Ultimately, that’s a very good change. I would even argue that our sense of responsibility to that system has changed. We can do more to protect the wrongly accused and the innocent victim, therefore we have the responsibility to do more. While original claims of DNA-based exonerations were met with skepticism and automatic objection, prosecutors now take a more thoughtful approach.
But, while we should appreciate the relative lightening-like speed with which we have leveraged the benefits of DNA in a criminal justice system designed to move slowly, we should also recognize how far we have to go. Four hundred thousand untested rape kits nationwide? Seriously? It shouldn’t be news that the Grim Sleeper was convicted with familial DNA analysis. It should be standard operating procedure.
Somewhat ironically I’ve spent the week in Manila, the Philippines with forensic DNA pioneer George Sensabaugh speaking to law and forensic science students about the impact that DNA has had on criminal justice systems since its introduction. In other words, none of my audience was alive for the Pitchfork conviction, and many weren’t even around when O.J. Simpson was declared not guilty. As I looked at the picture of Pitchfork on my PowerPoint slide, and talked about all the future applications of DNA technology that were contained in that one case, it struck me that our next responsibility is to keep the next generation of forensic scientists, prosecutors and defense attorneys inspired. Newness and novelty were great motivators for the scientists and attorneys responsible for DNA’s seismic impact over the last two decades. But DNA has been around long enough now for Colin pitchfork to qualify for, and be denied, parole.
As a new generation of scientists and lawyers integrate into criminal justice systems throughout the world, it’s important to ensure that they are not just good scientists and lawyers. As emphasized at our conference in Manila, “science in the service of society,” must remain the core message of our educational efforts.
