Fortinet Cures Mobile Phone “Curse of Silence/CurseSMS” Attack
Fortinet® - the pioneer and leading provider of unified threat management
(UTM) solutions - today announced that its FortiGuard®
Global Security Research Team has released a new free software application to help users
recover from the recently discovered “Curse of Silence” mobile attack (also
known as CurseSMS).
Mobile phones that are vulnerable to
the “Curse of Silence” attack include Nokia phones running SymbianOS S60 2nd
Edition Feature Pack 2, 2nd Edition Feature Pack 3, 3rd Edition, and 3rd
Edition Feature Pack 1. This includes several Nokia phones of the “N” series up
to the N95 and of the “E” series up to the E90, as well as older Nokia models
such as the 6680.
Fortinet’s
FortiCleanUp is a range of free tools running on Symbian™OS
S60-powered mobile phones, and is designed to help people fix their phones once
they have been attacked by security threats.
The “Curse of Silence/CurseSMS” attack is a remote SMS/MMS denial of service that was recently discovered by Tobias Engel, and revealed at the 25th Chaos Communication Congress. The attack involves sending a specially crafted SMS to potential targets. Upon receipt of the SMS message containing the attack, the targeted person’s mobile phone will be unable to receive further SMS or MMS messages. Depending on the operating system version of the targeted mobile phone, the device may require a factory reset to properly function again.
The FortiCleanUp tool for Curse of Silence/CurseSMS automatically scans and removes malicious SMS/MMS messages that are preventing the proper functioning of the handset.
For complete real-time protection, the FortiGuard team recommends the installation of Fortinet’s FortiClient Mobile on mobile devices. This security application provides unified security agent features including personal firewall, IPSec VPN, antivirus, antispyware and SMS anti-spam. FortiClient’s protection agent is powered by FortiGuard security subscription services to help protect devices against today’s blended threats. FortiClient Mobile provides light-weight, unified security agent features and is available for Microsoft® Windows Mobile™ and SymbianOS S60 operating systems.
