In addition, since some apps could themselves be malware , their functionality and activities should be limited for example, restricting the apps from accessing location information via GPS , blocking access to the user's address book, preventing the transmission of data on the network , sending SMS messages that are billed to the user, etc. There are three prime targets for attackers: There are a number of threats to mobile devices, including annoyance, stealing money, invading privacy, propagation, and malicious tools.
The source of these attacks are the same actors found in the non-mobile computing space: Some mobile phone models have problems in managing binary SMS messages. It is possible, by sending an ill-formed block, to cause the phone to restart, leading to the denial of service attacks. If a user with a Siemens S55 received a text message containing a Chinese character, it would lead to a denial of service. This attack is called "curse of silence". A study on the safety of the SMS infrastructure revealed that SMS messages sent from the Internet can be used to perform a distributed denial of service DDoS attack against the mobile telecommunications infrastructure of a big city.
The attack exploits the delays in the delivery of messages to overload the network. Another potential attack could begin with a phone that sends an MMS to other phones, with an attachment. This attachment is infected with a virus. Upon receipt of the MMS, the user can choose to open the attachment. If it is opened, the phone is infected, and the virus sends an MMS with an infected attachment to all the contacts in the address book.
There is a real-world example of this attack: A user installs the software, as received via MMS message. Then, the virus began to send messages to recipients taken from the address book. The attacker may try to break the encryption of the mobile network. The GSM network encryption algorithms belong to the family of algorithms called A5. Due to the policy of security through obscurity it has not been possible to openly test the robustness of these algorithms.
There were originally two variants of the algorithm: Since the encryption algorithm was made public, it was proved it was possible to break the encryption: In addition, tracing of mobile terminals is difficult since each time the mobile terminal is accessing or being accessed by the network, a new temporary identity TMSI is allocated to the mobile terminal. The TSMI is used as the identity of the mobile terminal the next time it accesses the network. The TMSI is sent to the mobile terminal in encrypted messages. Once the encryption algorithm of GSM is broken, the attacker can intercept all unencrypted communications made by the victim's smartphone.
An attacker can try to eavesdrop on Wi-Fi communications to derive information e. This type of attack is not unique to smartphones, but they are very vulnerable to these attacks because very often the Wi-Fi is the only means of communication they have to access the internet.
The security of wireless networks WLAN is thus an important subject. Initially, wireless networks were secured by WEP keys. The weakness of WEP is a short encryption key which is the same for all connected clients. In addition, several reductions in the search space of the keys have been found by researchers. Now, most wireless networks are protected by the WPA security protocol. The major improvements in security are the dynamic encryption keys.
For small networks, the WPA is a " pre-shared key " which is based on a shared key. Encryption can be vulnerable if the length of the shared key is short. With limited opportunities for input i. This increases the likelihood that an attacker succeeds with a brute-force attack. As with GSM, if the attacker succeeds in breaking the identification key, it will be possible to attack not only the phone but also the entire network it is connected to. Many smartphones for wireless LANs remember they are already connected, and this mechanism prevents the user from having to re-identify with each connection.
However, an attacker could create a WIFI access point twin with the same parameters and characteristics as the real network. Using the fact that some smartphones remember the networks, they could confuse the two networks and connect to the network of the attacker who can intercept data if it does not transmit its data in encrypted form.
Lasco is a worm that initially infects a remote device using the SIS file format. The smartphone thus believes the file to come from a trusted source and downloads it, infecting the machine. Security issues related to Bluetooth on mobile devices have been studied and have shown numerous problems on different phones.
One easy to exploit vulnerability: An attacker only needed to connect to the port to take full control of the device. The attacker sends a file via Bluetooth. If the recipient accepts, a virus is transmitted. For example: Cabir is a worm that spreads via Bluetooth connection. The user must accept the incoming file and install the program.
After installing, the worm infects the machine. The mobile web browser is an emerging attack vector for mobile devices. Just as common Web browsers, mobile web browsers are extended from pure web navigation with widgets and plug-ins, or are completely native mobile browsers. Jailbreaking the iPhone with firmware 1. In this case, there was a vulnerability based on a stack-based buffer overflow in a library used by the web browser Libtiff.
A vulnerability in the web browser for Android was discovered in October A significant difference with the iPhone vulnerability was Android's sandboxing architecture which limited the effects of this vulnerability to the Web browser process. Smartphones are also victims of classic piracy related to the web: The big difference is that smartphones do not yet have strong antivirus software available.
Sometimes it is possible to overcome the security safeguards by modifying the operating system itself. As real-world examples, this section covers the manipulation of firmware and malicious signature certificates. These attacks are difficult. In , vulnerabilities in virtual machines running on certain devices were revealed. It was possible to bypass the bytecode verifier and access the native underlying operating system. In it was possible to manipulate the Nokia firmware before it is installed, and in fact in some downloadable versions of it, this file was human readable, so it was possible to modify and change the image of the firmware.
In theory smartphones have an advantage over hard drives since the OS files are in ROM , and cannot be changed by malware. However, in some systems it was possible to circumvent this: When an application is installed, the signing of this application is verified by a series of certificates. One can create a valid signature without using a valid certificate and add it to the list. With firmware changes explained above it is very easy to insert a seemingly valid but malicious certificate. Juice Jacking is a physical or hardware vulnerability specific to mobile platforms. Utilizing the dual purpose of the USB charge port, many devices have been susceptible to having data exfiltrated from, or malware installed onto a mobile device by utilizing malicious charging kiosks set up in public places or hidden in normal charge adapters.

Jail-breaking is also a physical access vulnerability, in which mobile device users initiate to hack into the devices to unlock it, and exploit weaknesses in the operating system. Mobile device users take control of their own device by jail-breaking it, and customize the interface by installing applications, change system settings that are not allowed on the devices. Thus, allowing to tweak the mobile devices operating systems processes, run programs in the background, thus devices are being expose to variety of malicious attack that can lead to compromise important private data.
In , researcher from the University of Pennsylvania investigated the possibility of cracking a device's password through a smudge attack literally imaging the finger smudges on the screen to discern the user's password. As smartphones are a permanent point of access to the internet mostly on , they can be compromised as easily as computers with malware. A malware is a computer program that aims to harm the system in which it resides.
Trojans , worms and viruses are all considered malware. A Trojan is a program that is on the smartphone and allows external users to connect discreetly.
Mobile security - Wikipedia
A worm is a program that reproduces on multiple computers across a network. A virus is malicious software designed to spread to other computers by inserting itself into legitimate programs and running programs in parallel. However, it must be said that the malware are far less numerous and important to smartphones as they are to computers. Nonetheless, recent studies show that the evolution of malware in smartphones have rocketed in the last few years posing a threat to analysis and detection. Typically an attack on a smartphone made by malware takes place in 3 phases: Malware often uses the resources offered by the infected smartphones.
It will use the output devices such as Bluetooth or infrared, but it may also use the address book or email address of the person to infect the user's acquaintances. The malware exploits the trust that is given to data sent by an acquaintance. Infection is the means used by the malware to get into the smartphone, it can either use one of the faults previously presented or may use the gullibility of the user.
Infections are classified into four classes according to their degree of user interaction: Once the malware has infected a phone it will also seek to accomplish its goal, which is usually one of the following: Once the malware has infected a smartphone, it always aims to spread one way or another: Here are various malware that exist in the world of smartphones with a short description of each. Mobile ransomware is a type of malware that locks users out of their mobile devices in a pay-to-unlock-your-device ploy, it has grown by leaps and bounds as a threat category since Mobile ransomware poses a significant threat to businesses reliant on instant access and availability of their proprietary information and contacts.
The likelihood of a traveling businessman paying a ransom to unlock their device is significantly higher since they are at a disadvantage given inconveniences such as timeliness and less likely direct access to IT staff. Recent ransomware attack has caused a stir in the world as the attack caused many of the internet connected devices to not work and companies spent a large amount to recover from these attacks.
Below is a diagram which loads the different behaviors of smartphone malware in terms of their effects on smartphones: We can see from the graph that at least 50 malware varieties exhibit no negative behavior, except their ability to spread. There is a multitude of malware. This is partly due to the variety of operating systems on smartphones.
However attackers can also choose to make their malware target multiple platforms, and malware can be found which attacks an OS but is able to spread to different systems. To begin with, malware can use runtime environments like Java virtual machine or the. NET Framework. They can also use other libraries present in many operating systems.
In practice, this type of malware requires a connection between the two operating systems to use as an attack vector. Memory cards can be used for this purpose, or synchronization software can be used to propagate the virus. The security mechanisms in place to counter the threats described above are presented in this section. They are divided into different categories, as all do not act at the same level, and they range from the management of security by the operating system to the behavioral education of the user. The threats prevented by the various measures are not the same depending on the case.
Considering the two cases mentioned above, in the first case one would protect the system from corruption by an application, and in the second case the installation of a suspicious software would be prevented. The first layer of security in a smartphone is the operating system OS. Beyond needing to handle the usual roles of an operating system e. A central paradigm in mobile operating systems is the idea of a sandbox.
Since smartphones are currently designed to accommodate many applications, they must have mechanisms to ensure these applications are safe for the phone itself, for other applications and data on the system, and for the user. If a malicious program reaches a mobile device, the vulnerable area presented by the system must be as small as possible.
Sandboxing extends this idea to compartmentalize different processes, preventing them from interacting and damaging each other. Based on the history of operating systems, sandboxing has different implementations. For example, where iOS will focus on limiting access to its public API for applications from the App Store by default, Managed Open In allows you to restrict which apps can access which types of data. Above the operating system security, there is a layer of security software. This layer is composed of individual components to strengthen various vulnerabilities: It contains software components that have learned from their experience with computer security; however, on smartphones, this software must deal with greater constraints see limitations.
A mobile antivirus product would scan files and compare them against a database of known mobile malware code signatures. When an application passes the various security barriers, it can take the actions for which it was designed. When such actions are triggered, the activity of a malicious application can be sometimes detected if one monitors the various resources used on the phone.
Depending on the goals of the malware, the consequences of infection are not always the same; all malicious applications are not intended to harm the devices on which they are deployed. The following sections describe different ways to detect suspicious activity.
The various points mentioned above are only indications and do not provide certainty about the legitimacy of the activity of an application. However, these criteria can help target suspicious applications, especially if several criteria are combined. Network traffic exchanged by phones can be monitored.
One can place safeguards in network routing points in order to detect abnormal behavior. As the mobile's use of network protocols is much more constrained than that of a computer, expected network data streams can be predicted e. In the production and distribution chain for mobile devices, it is the responsibility of manufacturers to ensure that devices are delivered in a basic configuration without vulnerabilities.
