Risk: Informational
Recent testing by NTA has found that the danger posed by BlackBerry hijacking, 'blackjacking', is minimal compared to real threats that BlackBerry users may encounter.
Despite blackjacking offering some unique attack methods, it is considered to pose no greater threat than a normal Trojan being emailed to a desktop PC.
NTA found that many BlackBerry users don't password protect their devices and that if there are no firewalls used to separate the BlackBerry server from the internal network, the architecture can be insecure. BlackBerry servers are also often left in a default state, with no limitation given to what software can be installed or whether intranets can be accessed.
BlackBerry users can help to protect themselves against malicious attacks by following simple rules, such as password protecting their device and ensuring that it remains in a safe place and is never left unattended.
