A newly discovered form of malware attacks your Android phone to infect your wifi router.
In true hacker style, they like to keep you on your toes. So, rather than targeting and infecting your device directly, as per traditional ransomware, the Switcher Trojan hijacks your wifi router instead.
How does it work?
When you download the app, you are giving the Switcher Trojan the green light to switch out the router’s existing DNS server with a malicious one. Ultimately, this will redirect all traffic from your wifi connected devices on the network straight to the cyber criminals.
After the hackers have collected a heap of data, they’ll have all the ammo they need to carry out fraud and data theft. Not to mention that this sort of intrusion leaves you with an open network and vulnerable to further cyber-attacks.
According to Switcher Trojan statistics, Kaspersky researchers discovered that in less than four months 1,280 networks had been infected by the ransomware.
Due to backup servers, even if the attack is detected it can be extremely difficult to remove the infection.
What can you do?
Of course, you can never be 100% bulletproof when it comes to ransomware. But Kaspersky security experts recommend that users change the default login and create a password for the network router. Default credentials are often left unchanged by users, which leaves them particularly exposed.
It’s also important to make sure that you only download apps from the official Android store, rather than third party sources.
