IRecently hackers have been exploiting a hole in the default Linux NTP (Network Time Server) to perform denial of service attacks. Your PBX or other internal servers use this service to display the correct time on your phones or other devices. You are susceptible to this attack if you have port 123 UDP open to the internet forwarded to an internal server.
When it comes to hackers, they are shrouded in darkness and treachery. They lurk in the shadows, waiting for us to make a mistake and to steal our life savings, or other equally nefarious things. But there are a few assumptions that they make concerning their prey, and they wish to hide these from us at all costs.
Lately, there's been a string of computer security issues making the news, like the vulnerability found within Internet Explorer, the Heartbleed bug, and the host of issues associated with the recently-expired Windows XP. Is it possible that the security patches issued by Microsoft are making the problem worse for users of older systems like Windows XP?
Just like the dark waters of the benthic ocean trenches, the Internet is filled with wondrous creatures that have never been seen before. However, there are also rather ugly things lurking in the depths as well. No matter how deep you swim, there are always the deep sea phishermen that will try to rip you away from everything you hold dear – your personal and professional data.
In high school, there were always the rebellious kids who never wanted to do what their teachers said. They would vandalize the bathroom stalls, walk around the halls without permission, skip classes, and make the school an overall unpleasant environment. The teachers eventually decided that enough was enough, and they banned certain privileges that the students had. Bathroom breaks became timed. Hall monitors stalked the halls looking for troublemakers. Our liberty was stolen by these hooligans.
