Last week we blogged about how 79 percent of mobile malware was directed at Android and that SMS Trojans represent half of all malicious applications.
While most SMS messages are free or very cheap, there’s a special category called “Premium SMS” where each message you send can cost you up to $10.
But there’s a SMS fraud network that is particularly active in Eastern Europe and involves trojanized apps luring users with the usual culprits: fake software updates and porn.
Our journey starts with a standard (non-rooted) Nexus 4 phone:
Who doesn’t own a mobile phone nowadays? Whether you have an old-school flip phone or a newer smartphone, you may already have been bothered by rogue SMS text messages.
Cyber-crooks are spamming through every avenue they can, hoping to lure their victims into revealing personal information or tricking them into sending costly text messages.
And it’s not just cyber-criminals you should be worried about. Have you ever received a message from someone you don’t know? Well, these could be attempts to blackmail you or ruin your day.
The above screenshot shows a technique, also known as smishing (SMS phishing), that is rather effective because it reaches your own personal phone. While (almost) everybody knows about email phishing scams, not many people are aware of the equivalent for phones.
Today we are going to be talking about advertising, specifically misleading advertising. Whether it’s on TV or on the internet, in magazines and newspapers, we see misleading advertising all of the time, you see it all of the time, whether you realize it or not. So how do you spot it? Well, that is one of the things we are going to cover here. Once you know what to look for, you’ll be able to spot it yourself, in most cases without having to look any further than the image in the advert.
Our first example of misleading advertising is an advert promoting a “Free Scan”, but failing to mention it is only the scan that is free. In fact, you have to pay before it will fix anything it claims needs fixing. It should also be noted that in the vast majority of cases, most “problems” found are not problems at all. Registry cleaning software are very fond of using this tactic to promote their products, as are so-called “system cleaners” such as SpeedUpMyPC.
