Check it at and make not of how often it changes.īasically think of password security like an open window. Problem is, it's not easy to get a unique IP address on your phone and you may end up allowing tens of thousands of IP addresses to ensure yours is allowed through. The 2nd protection you have is your IP address. We see a large number of port scans on our network and it's probably the number one reason IP's get blocked. Then if you set that appliance to detect and auto block port scans that will help. ![]() If you have a hardware firewall appliance like a Cisco or Watchguard, you can limit access to that port to specific IP addresses. In order to reach the DVR, they have to have the port that it listens on. But a port scanner can get around that quickly. Putting the DVR on a hard to guess port might be a first good move. What's worse, your DVR is likely programmed to "phone home" as soon as you get it connected. There are probably backdoors they can use to go around any password. I'm so glad to see people getting around to this kind of thing.Īny Internet device made outside the US and especially made in China is subject to backdoors and security risks. I know most of the devices in my home must have the WPA2 code to access the router and one can restrict the MAC addresses to known devices and password the router it's self, Does this mean that the camera system rely on computer access in order to be operational or are there camera systems that work on SD cards have the ability to contain their own logon and the fact that that log on is broadcast over a great distance produce the vulnerability for scanners to interept the logon and duplicate it for access?Īre there work arounds for this such as prohibiting remote logon to the computer still leave a vulnerability as once the router is compromised, a hacker could add a foreign MAC address and intercept access from any computer or cell phone connecting to the network?Ī little knowledge would help so that when I hire someone to do the job, I can make sure he is a true professional and does not leave the back door unlocked. Since the security camera I am considering will be 700 ft away from the router, I understand I will need a amplified access point such as a AP600EX which uses a bidirectional antenna, and a range Extender wuch as a AP600EX which greatly increases the vulnerability for a scanner to pick up the signal. I am very interested in your post and have some questions. Let's just hope that the good guys (researchers) find them before those who would use them for their own nefarious purposes. ![]() ![]() Although it's hard to beat the value of these cheap devices, it's just a matter of time before more and more of these severe remote vulnerabilities are found as they become more prevalent. I've always wondered how many inadvertent (vulnerabilities) and purposeful (backdoors) security issues there are in these ubiquitous, cheap, poorly-developed DVRs. I wouldn't be surprised if they never do. There's already a Metasploit aux/scanner module to discover vulnerable systems and dump the admin password.Īs far as I know neither Ray Sharp nor the rebranders have responded to this. your laptop, iPhone, PC, and whatever else. Possible attacks include accessing clear-text admin passwords, creepy unauthorized access with said account, as well as using the DVR as a pivot point for attacking other internal network resources, e.g. Changing this port might add a bit of security through obscurity but you'd still be totally vulnerable. My apologizes if this is a re-post but has everyone heard about the vulnerabilities in Ray Sharp DVRs as well as rebranded DVR products by Swann, Lorex, URMET, KGuard, Defender, DEAPA/DSP Cop, SVAT, Zmodo, BCS, Bolide, EyeForce, Atlantis, Protectron, Greatek, Soyo, Hi-View, Cosmos, and J2000?īasically, if you use one of these devices, you probably ought not port-forward TCP 9000 from the internet unless you are restricting access by source. ![]()
