Warning for users of Android. There are new dangerous trojan attacks and spread quickly through SMS from other mobile users. Your phone can be taken over and driven to crime in cyberspace.
Researchers at Symantec found some trojan infected phones – phones that are infected then it will attack other phones, by sending an SMS to a phone number in their address book.
Because SMS looks like from a friend, then the attack will be more effective. The new Trojan dubbed “botnet” attack by “recruiting” other phone to send spam to my friends. SMS are sent usually contains a link to download a free game or prize winning notification.
But what happens is when the link is clicked, the trojan is installed. The phone is infected it then becomes part of the control of cyber criminals to send spam to other victims.
The phone is “controlled” by the trojan can be used to get money for the hacker in cyberspace through spam advertisements, and through the use of premium SMS service which is then added to the user’s bill.
These attacks are an alarming new trend in the category of malicious software, Symantec officials said. The attack is the same as the type of mass spam attacks on your PC.
Symantec predicts that this trend will continue and spread. “While botnets sending spam is not new, mobile technology has opened up new intermediaries to hacker attacks in cyberspace that uses techniques of social engineering attacks and spam that proved successful on mobile devices,” Symantec said in its official blog.
“Installing trojans hidden from the user and removed the traces of their presence when installing official application to the user device. Victim only saw the advertised application, tricking victims who believe that all applications are safe.”
“In 2013, mobile adware or ‘madware’ would be a major nuisance, disturbing and potentially expose users location details, contact information, and identification devices for hackers. Madware – who slipped to the user when they download an application – frequently sends a notification pop -up notification to the board, adding icons, changing the browser settings and gather personal information.
Only in the last nine months, the number of applications including the most aggressive form of madware has increased by as much as 210 percent.
