Dutch Hacker Hijacks iPhones. Offers Owners Fix…for Cash.

Jailbreaking your iPhone can provide increased functionality and less restrictions but it also seems it can now also bring with it a massive security risk.

There are reports that an enterprising Dutch hacker has preyed on many handsets operated by T-Mobile Netherlands, issuing notices that alert the user that their iPhone is vulnerable unless they paid €5 for a fix.

It is thought that the vulnerability centres on a feature of the jailbreak itself, the enabling of a SSH (Secure Shell) service that has a default root password. The attacker was able to determine which jailbroken devices were viable by performing a port scan on the T-Mobile network, issuing the default password when prompted. Many Windows and Mac applications automate the jailbreaking process meaning many users don’t have the necessary technical skills to identify any vulnerabilities on their device and then deal with them once noted.

Compromised iPhone’s would read the following message:

When the user visits the website, they are directed to a PayPal page with a prompt to pay the €5. Once the funds are sent, the hacker would then send the instructions to patch the vulnerability, requiring the user to download an SSH client for their desktop and issue a few remote commands.

There was one further development when affected users started looking to forums for advice. The hacker had a slight sense of remorse and posted instructions on how to patch the hole, identifying the fact that attacker was probably more of an opportunist rather than a malicious criminal.

Apple may see this incident as yet another reason that iPhone users should not take to jailbreaking their devices. Out of the box, the iPhone is equipped to deal with security vulnerabilities but when you jailbreak, security suddenly becomes your problem.
