Phishing, malicious websites, and background-running software are classic Web piracy threats that smartphones are susceptible to, and they don't have strong antivirus software available to protect them.

The management of SMS and MMS can also be a point of attack, with some mobile phone models having problems in managing binary SMS messages.

If a user with a Siemens S55 receives a text message containing a Chinese character, it can cause the phone to restart, leading to a denial-of-service attack.

The "curse of silence" is another attack that can occur if a user enters an email address over 32 characters on a Nokia phone, causing the e-mail handler to become dysfunctional.

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.

Malware attacks on smartphones typically involve three phases: infection, accomplishment of the goal, and spread of the malware to other systems.

Malware often uses the resources of the infected smartphone, such as Bluetooth or infrared, and may also use the address book or email address of the person to infect the user's acquaintances.

There are several types of attacks that can compromise the security of your mobile device. Some attacks derive from flaws in the management of Short Message Service (SMS) and Multimedia Messaging Service (MMS), which can lead to denial-of-service attacks or even complete dysfunction of the email handler.

For example, sending an ill-formed block of characters to a phone can cause it to restart, while entering an email address over 32 characters on a Nokia phone can lead to a denial of service. In fact, 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.

Other attacks are based on flaws in the OS or applications on the phone, such as phishing, malicious websites, and background-running software. Smartphones are also victims of classic Web piracy, but they don't yet have strong antivirus software available.
