Mobile phones are generally not safe from being eavesdropped and blocked by mobile phone jammers.

The ability to clone ESD in analogue AMPS phones and to use them to make free calls and to listen in to calls is legend, popularized by notorious hackers like Kevin Mitcnick who was one of the first to hack into Nokia phones.

Digital phones are of course a lot more difficult to hack into, but are easy to jam.

n October 2003, an Israeli scientific team showed a way to break into mobile phone calls on ubiquitous GSM networks, potentially allowing eavesdroppers to listen in on conversations and even take on a caller's identity. They cracked the A5 algorithm which is mean to encrypt calls  The GSM Association says they're "not worried" though.

Security Concerns ate still slowing Mobile Application Deployment [more...]

In 1998, the Smartcard Developer Association (SDA) and two U.C. Berkeley researchers jointly claimed that GSM cellphones are susceptible to SIM cloning.

Mobile and Smartphone Worms, Viruses, Trojans and Malware & Hacking
A group of underground virus writers has showed off "Cabir", what is believed to be the world's first worm that can spread on advanced mobile phones, but security software companies say the virus had no malicious code attached.

Advisory on malicious one-ring calls  

NTT DoCoMo have been advising their customers not to call back a number in the received call history from an unknown number, which when called back, the caller is connected to "dating" site advertisements or adult content guide, otherwise known as "one-ring" calls.


GPRS Hacking
GPRS networks have also been vulnerable to hacking.
. In June 2003, a security flaw was reported in the Nokia GGSN (Gateway GPRS support node) that could have lead to a Denial of Service (DoS) attack by hackers. The A5 hack also affects GPRS.
[See: Nokia GPRS network could be hacked]

Israeli-based ECtel says that an unnamed major USA based wireless carrier has ordered its new lawful interception solution for packet data networks. The order was placed following and intensive and thorough evaluation process of various competitive solutions. ECtel's flexible X-Probe PD solution was designed to help service providers comply with new Lawful Interception regulations for data networks monitoring.

SMS Hacking:
A Security flaw was also reported at Verizon's SMS service in August 2003. The bug allowed any person to easily view mass lists of SMS messages sent to Verizon Cellular customers, including the telephone number and the text in the message

In January 2003, Microsoft and Orange UK investigated whether hackers sent rogue software to cell phones using Microsoft's Smartphone 2002 operating system

Bluetooth Hacking
There have also been warnings that Bluetooth Class I devices pose hacking & security risk. In addition,
preliminary research from security firm A.L. Digital suggests a number of security problems with Bluetooth-enabled mobile phones from Nokia and Ericsson.

Mobile Phone Jammers & Detectors.

Mobile Phone Jammers are now also the rage. They come in various permutations, including a new device that looks like a normal cellphone and whihc can block any calls within a 100m radius. [ See New GSM Jammer Looks Like a GSM Cellphone]

Using Mobile Phones as bugs
Mobile phones can now easily be adapted to be used as bugs. A
t first sight they look like regular cell phones same size, same shape, same overall appearance. But beneath the digital face is a spyphone. And any Nokia phone can be adapted to act as a spyphone and you can monitor the person with the spy phone at any time

[See Worlds First Mobile Spyphone Launched].

Camera Phones
For many organizations, camera phones represent a significant liability or security risk such as inappropriate candid shots of employees, pictures of production lines.

While the quality of most cameras in current phones is poor, it nonetheless represents a potential channel for leaks of sensitive data or other images that can produce unintended
consequences. [See Camera phones a threat to industrial secrets].

Secure Mobile Phones.
A number of manufacturers have released phones that prevent bugging over the air. These encrypt calls using for example GSM data channel to carry the voice call. The Korean Government recently admitted to developing Anti-Tapping Mobile Phones.

New GunPhone

Hitting the 5, 6, 7 and 8 buttons on the gunphone fires four .22 caliber rounds in quick succession.

See the secret video of the GunCellphone  in action


At first sight it looks like a regular cell phone same size, same shape, same overall appearance.

But beneath the digital face lies a .22-caliber pistol, a phone gun capable of firing four rounds in quick succession with a touch of the otherwise standard keypad.
European law enforcement officials stunned by the discovery of these deadly decoys say phone guns are changing the rules of engagement in Europe.

Airport authorities across Europe are implementing systems to X-ray all cell phones

The security aspects of GSM are detailed in GSM Recommendations:

02.09 - Security Aspects
02.17 - Subscriber Identity Modules
03.20 - Security Related Network Functions
03.21 - Security Related Algorithms"

The subscriber is uniquely identified by the International Mobile Subscriber Identity (IMSI). This information, along with the individual subscriber authentication key (Ki), constitutes sensitive identification credentials analogous to the Electronic Serial Number (ESN) in analog systems such as AMPS and TACS.

The design of the GSM authentication and encryption schemes is such that this sensitive information is never transmitted over the radio channel. Rather, a challenge-response mechanism is used to perform authentication. The actual conversations are encrypted using a temporary, randomly generated ciphering key (Kc).

Components Required:
For the authentication and security mechanisms to function, three elements (SIM, handset, and GSM network) are required. This distribution of security credentials and encryption algorithms provides an additional measure of security both in ensuring the privacy of cellular telephone conversations and in the prevention of cellular telephone fraud.

  • GSM handset or MS
    The MS identifies itself by means of the Temporary Mobile Subscriber Identity (TMSI), which is issued by the network and may be changed periodically (i.e. during hand-offs) for additional security.

  • Subscriber Identity Module (SIM)
    The SIM contains the IMSI, the individual subscriber authentication key (Ki), the ciphering key generating algorithm (A8), the authentication algorithm (A3), as well as a Personal Identification Number (PIN). The GSM handset contains the ciphering algorithm (A5). The encryption algorithms (A3, A5, A8) are present in the GSM network as well.
  • GSM Network
    The Authentication Center (AUC), part of the Operation and Maintenance Subsystem (OMS) of the GSM network, consists of a database of identification and authentication information for subscribers. This information consists of the IMSI, the TMSI, the Location Area Identity (LAI), and the individual subscriber authentication key (Ki) for each user.
