1 Protecting Android Mobile Devices from Known Threats Android OS A Popular Target for Hacks White Paper Zero Trust Mobile Security An Introduction to the BETTER Mobile Security Platform BETTER at work. Contact us BETTER Mobile Security 110 Fifth Avenue New York, NY info@better.mobi In the tech industry, it s a truism that hackers focus their attention on afflicting the largest number of targets possible, resulting in a perception that market giants are riddled with vulnerabilities. Google s Android operating system is just such a target. According to an IDC study, Android possesses an 81.1% share of the smartphone market. Numbers that high are irresistible to hackers which is why Android devices need to be protected from unauthorized access. Add to the equation too that the Android operating system has been implemented on many disparate devices designed by myriad vendors. This distributed implementation scenario has fragmented Android s native security model, which has resulted infringement a variety of the respective of openings owner s that property. of cyber attackers can exploit. Common Android Vulnerabilities Once an attacker gains access to a device s operating system, they can gain elevated privileges to monitor user activity, thereby putting personal data and security at risk. They can also execute malicious code and run unwanted programs to bend the device to their will. All of this can be done without the user suspecting that their device has been infected. Here are some of the most common Android vulnerabilities that malicious programmers seek to exploit. It should be noted that many of these vulnerabilities are inherent to mobile and Wi-Fi devices in general, and do not necessarily reflect a flaw in Android s design and implementation.

2 2 Executive Summary The increasing threats to mobile security. The cumulative number of mobile threats is expected to double from the previous year reaching over 8 million spread across devices and applications 1. While analysts have identified the need for real-time, self-aware and self-protecting endpoints, MDM/ EMM and MAM solutions that do not address real time threats still dominate the market. A zero trust approach for protecting today s mobile user. According to cyber security research, the vulnerabilities in mobile devices and apps will become even greater risks in Zero trust is an approach to security that follows the mantra of never trust, always verify. It views every entity, including networks and apps, as hostile and that a breach is inevitable. Operating from that perspective sets a mandate for a more complete security solution as opposed to traditional perimeter-based approaches. When applied to mobile security, a zero trust approach continuously monitors and verifies exactly what is happening on the network, the mobile device itself, the apps installed on the device, and actively detects and prevents threats in real time. In order for a zero trust mobile security solution to be effective, it has to operate based on the following principles: You cannot trust the network You cannot trust the device You cannot trust the apps You cannot trust the user A zero trust approach follows the mantra of never trust, always verify. In this white paper, the following will be covered: The current mobile threat landscape and how there is an immediate need for a zero trust mobile security solution An explanation of zero trust How to apply a zero trust model to mobile security How a zero trust solution for mobile devices needs to operate under the principles of secure and verify How BETTER Mobile Security provides the only comprehensive zero trust mobile security solution that is able to secure and verify mobile devices, apps, users and the network in real time BETTER s zero trust mobile security solution operates under the assumption that an attack on a mobile device will happen, and that the network, device, apps, and user can be hostile. Our solution provides both the security to prevent such attacks as well as the measures necessary to protect if a breach should occur.

3 3 The Mobile Threat Landscape Attacks on mobile devices are rapidly evolving. Forrester Research reported that over 61% of enterprises stated that app security is their greatest mobile security challenge. The mobile threat landscape is changing rapidly. Mobile attackers are taking traditional methods from the wired world and adapting them to the mobile one, as well as coming up with new, never before seen tactics that take advantage of the new avenues mobile devices offer into an organization s network. Mobile devices are constantly switched on and they bounce from one connection to another, allowing a hacker to have multiple attempts to gain access to a device. A new end-point of corporate risk. Kapersky Labs reported that attacks on mobile devices have increased by over 400% in the last year. Mobile threats can wreak havoc on both mobile devices and the corporate network. Once a trusted device has been compromised, an attacker may have priviledged access to the corporate network. Depending on the type of attack, they will be able to decrypt secure communications, intercept traffic to and from the device, install apps or keyloggers, take screen captures, access any information stored on the device or within apps, including passwords, , and text messages. These attacks can go as far as to give themselves root privileges, jailbreak the device, or leverage the device as part of a mobile botnet to mount DDoS attacks. Connected by design, vulnerable as a result. Mobile devices connect to upwards of 10x more networks than other end-point devices. Our research indicates that mobile devices connect to upwards of ten times more networks than other end-points. The tools required to intercept, modify, and push network data are relatively inexpensive, readily available, and their uses are becoming more sophisticated and nefarious. Man-in-the-Middle (MitM) attacks can perform active eavesdropping, intercept, and alter traffic between a mobile device and a remote server. The user believes they are interacting with a known and trusted entity but, in fact, they are being rerouted through an attacker controlled device. Once connected to the attacker s device, all communication going to and from the victim s mobile device is seen by the attacker, regardless of encryption such as SSL. Malicious apps and their means of entry. Malicious apps can come from anywhere and wreak all kinds of havoc. With no means of protection, the recommendation to users has always been to not download apps from unknown sources. This is not a viable approach, because it requires device users to know what is a trusted source and what is not. Another problem with this approach is that today s

4 4 attackers are adept at convincing users to trust that an app is genuine and beneficial to their needs. Malicious apps can steal passwords, , text messages and corporate data. They can also log keystrokes and screen scrape. Malicious apps can even be side-loaded onto an ios device through the use of stolen or illegally-acquired enterprise or developer certificates. This gives the attacker the ability to gain access to encrypted data, bypass VPN tunneling, and break the OS sandbox, providing access to containerized apps. This access enables the attacker to view the contents of secure containers and wrapped apps, thus nullifying those attempts to protect sensitive data. The introduction of WireLurker and Masque attacks formally marked the beginning of a new era of ios vulnerability. Today s malicious apps appear and behave just like the authentic versions. WireLurker: the advent of ios threats. An ios malware example, named Wirelurker, uses a stolen enterprise certificate and a vulnerability in how the trust of the bundle identifier works to install a malicious app onto a mobile device. Wirelurker was first brought to light by Palo Alto Networks 2. It bypasses the security features on ios devices and installs malicious apps onto it, without the need of first jailbreaking the device. The WireLurker Trojan installs itself on an OS X machine, rooting itself into the operating system, and then waits until an ios device connects to the computer. It then abuses the trusted pairing relationship between the devices to read the mobile device s serial number, phone number, itunes store identifier, plus a host of other sensitive information. This data is all sent to the attacker s remote server. It then installs a series of malicious, though benign looking, apps onto the mobile device. The Wirelurker threat shows how vulnerable ios devices are to attacks and that the path to infection can come from anywhere. Masque attacks: appearances can be deceiving. BYOD Explosion: Gartner has stated that the number of employeeowned devices used for work will be greater than corporate-owned by Masque attacks get users to install malicious apps on their devices through refined social engineering techniques such as phishing s or messages from trusted sources. These apps take the form of updates to existing apps and are therefore not detectable by traditional MDM and EMM solutions. Once on the device, they have access to all data stored within the app. Since these apps are by all appearances genuine and have the same bundle ID, they go undetected by MDM and EMM solutions, so it is virtually impossible to know if your data has been compromised. What can be done to protect my mobile device? Today, MDM/EMM mobile security solutions offer little to no protection against these attacks. Hackers play a numbers game with the general public, since all they need is for just one person to slip up one time to gain access to a corporate network. These attacks

5 5 happen fast, compromising devices, apps, or communications in the blink of an eye, without being detected. To fully secure mobile devices from threats, the network, users, apps and the device itself all need to be viewed as potentially hostile. The solution must operate on the assumption that eventually the device will get into the wrong hands, apps will be compromised, and communications will be intercepted. The new generation of ios and Android advanced threats has demonstrated that mobile device management is not the same as mobile device security.
