ShieldsUP will also tell you your IP address, note it on a piece of paper for future reference (I collected all my results and added the IP to each test result so that I would not get mixed up in my results). We recommend weekly. False positive/negativesThe secret killer of VA solution value is the false positive. exploitable NetBIOS vulnerability messages from Rogers (every Monday at the same time). The Vulnerabilities in NetBIOS Information Retrieval is prone to false positive reports by most vulnerability assessment solutions. I decided NOT to test my NAS on the network, which is still being setup and well, because it is a Synology NAS and now I am quite leery of it - given my experience with the Synology router that is supposed to be locked down, but actually isn't (it's pretty buggy and many of the bugs I found were confirmed by others in 2 different Synology forums). Can't find what you're looking for? AVDS is alone in using behavior based testing that eliminates this issue. 2 weeks ago This directory is typically mode 0700, that is owner (root) only access. This may have sold a lot of systems some years ago, but it also stuck almost all VA solutions with deliberately inaccurate reporting that adds time to repairs that no administrator can afford. An attacker who successfully exploits this vulnerability could cause a target computer to become completely unresponsive. A vulnerability was found in Samba from version (including) 4.9 to versions before 4.9.6 and 4.10.2. Vulnerability is affected by personal factors as well as factors within the environment. - edited older SMBv1 implementations ran over NETBIOS, hence TCP/139, newer SMBv2 and later tend to use TCP/445 without NETBIOS. Found most of the ports closed, three open and just two stealth. Can rogers spend $300 to get a synology NAS device from BestBuy and figure out why the false alarm? You can also work around the NetBIOS name-service conflict issue by performing an operation that causes the TCP/IP stack to remove and then resend TCP/IP address notifications. Using NetBIOS for hacking is the probably the easiest way to hack remotely. 2 weeks ago If a NETBIOS session can be established at all via TCP port 139, the target is declared "vulnerable" with the remaining question being to what extent.
