you do understand that both wannacry and petyas are just exploits to something the user did not patch and most likely should not have been running for years anyway.  SMBv1 should of been disabled on your machines years ago ;)  Especially from a security point of view.

 

What you should take away from such things is, keep your stuff up to date with security patches.  Do not run old protocols that you do not actually need/use..  And make sure you have valid and current backup plan ;)

 

edit: From a IDS/IPS point of view that would run at your edge or at your core router in your network, not really on the host..  There are HIDS, or Host intrusion Detection Systems.  The two opensource or free versions that I am aware of are OSSEC and Tripwire had/has an opensource version and there is AIDE as well..

 

https://ossec.github.io/

 

Is the only one that I know of that would run on windows would be ossec, but then only as an agent.  You could also run and agent on alienvaults OSSIM, but this is more really a SIEM and also has a windows agent.  A SIEM would be part of any actual network..  But your not really going to find many deployed in a typical home setup ;)  While I run one - my home network is not in any way or form "typical" hehehe

 

For your typical home users yeah your best sort of solution would be something like malwarebytes.. But I would not really classify that as any sort of IDS or HIDS even..

 

If you ran say a router/firewall distro like pfsense, or ipcop or smoothwall, etc.. Then they have IDS/IPS that run on them snort and suricata.  Keep in mind that running such systems have a huge learning curve and if not correctly setup and maintain will either flood you with false positive (noise) or can pretty much break your network from being to do the stuff you want to do ;)

Otherwise, use Linux! :laugh:

Just last month, there were reports or Erebus resurfacing as a Linux variant of ransomware. Every OS has their flaws, it is a matter of staying up to date and doing your due diligence as the user. Just because you're using linux, doesn't make you impenetrable. Ever heard of Linux.Encoder.1?

That was a joke, if you didn't notice. Every OS is vulnerable. I wasn't boasting...

Hello,


Malware-based (or derived) intrusion detection/prevention has been a basic feature of most security suites for years.  The name of the feature set(s) which provide it vary between vendors, but pretty much every vendor out there has some kind of security layer which does this.

What the security suites need to do is stop the user from doing what they want and force them to PATCH Their systems ;)

 

Sorry that is enough p0rn for you now - time to reboot to patch!

Hello,

 

The anti-malware software that I use warns me when one of my systems is missing Windows updates.  I suspect it isn't unique in this, though I don't know how common a feature it is.

Now this was helpful. And yes I also agree that patching mostly does the purpose but I also think that a normal not so techy user must have a system installed that alerts any malware detection since they are becoming so much common.

+1.

I am in the middle of planning to replace my ASA5505 to a pfSense, as this little ASA doesn't have Gig ports, though I haven't found the suitable Mini PC yet. (don't wannt spend too much on it)

What is your budget?

Don't want to hijack this thread but if you meant my budget, I am thinking between 100/150$. I want one of those little mini-itx fanless box with at least 2 gig ports.

Well for $149 you could buy the sg-1000, official box from pfsense, that has 2 gig nics ;)   If your thinking of running pfsense anyway would be good option.

I have heard it's laggy and if I remember correct it doesn't support traffic shaping, not that I will do traffic shaping, but I like to have that option for learning purposes. ;)

They resolved that a while ago I do believe, in the 2.4 beta's  Had to do with the drivers not supporting altq

https://redmine.pfsense.org/issues/7199

 

but you could of worked around it with vlans..

now if only windows forced security patches....... :) combined with something along the lines of Sophos home AV/UTM 

https://home.sophos.com/ 

 

its free for home use.

 

i use my isps ability to filter websites also at the ISP level to sites that are deemed "risky" combined with Webroot Secure anywhere personally. As well as running each users account as a limited user and UAC when and if i need elevated privs.

I kept wannacrypt etc outside of work and at home by 1) patching regularly 2) disabling SMb 1.0 and 3) end user UTM. 4) up to date AV from a good vendor. 5) denying anyone (especially other IT staff) running as adm 24/7.

 

item 5 was the hardest to  implement at work, someone who should know better, but doesn't, same mindset as dont patch Ms stuff, they just break things..../faceplant. Wannacrypt demonstrated how wrong they were.

Have you been using it?

What impact does this make? 

I have been using the 2.4 beta's for quite some time at home update to current snap every few days, week at the most.  I have no need for any traffic shaping on my network.. So no I have not played with it in 2.4 beta's... I don't have a sg-1000 to play with I run my pfsense at home VM.  I could play with a sg-2440 at work, we are planning on replacing all our old juniper firewall/routers in branch locations here in the US with those..  First 1 has been running in NY office for a while.. Been rock solid, but it has no need for traffic shaping either they have a pretty fat pipe for what its used for and have never seen any issues or need for traffic shaping..  The old juniper couldn't even do 100mbps - now with the pfsense actually getting what we are paying for on that pipe, over even testing we did was over 300mbps.

 

If your not saturating your pipe - traffic shaping can be pointless.  And just cause you slowness and pain when there is no call for it.. If the pipe was new capacity and it carried traffic that needed to be prioritized then ok.  But that is not the case for these connections.

 

What impact does not running admin on your box for doing day to day?  This can be HUGE protection.. You should not be using god account for your day to day stuff.  Say your account is domain admin, which your logged into your machine with... While sure it makes it easy to access pretty much anything at any time.  If you get hit, whatever hit you now can hit anything on your network as god.. Not a good thing ;)  Shoot for that matter a simple mistake on your part and there goes all the user files on a share because you hit the wrong key ;)

 

Min security needed to perform the function is security 101, using your root/god account when your not in god mode is bad idea from any way you look at it..

Wannacrypt and most ransomware requires admin rights to encrypt systemwide, running as limited users minimises the amount of files it can encrypt, if it gets past other layers of protection, its also good security practise never to run with elevated privs day to day, When elevated rights are required, right click run as and enter an admin accounts creds.

 

 in the enterprise it could mean the difference between a minimal number of encrypted files and system wide domain encryption, if the multtiered, multivendor protection is compromised.

    • LibreWolf 152.0-1 by Razvan Serea LibreWolf is an independent “fork” of Firefox, with the primary goals of privacy security and user freedom. It is the community run successor to LibreFox. LibreWolf is designed to increase protection against tracking and fingerprinting techniques, while also including a few security improvements. This is achieved through our privacy and security oriented settings and patches. LibreWolf also aims to remove all the telemetry, data collection and annoyances, as well as disabling anti-freedom features like DRM. LibreWolf features: Latest Firefox — LibreWolf is compiled directly from the latest build of Firefox Stable. You will have the the latest features, and security updates. Independent Build — LibreWolf uses a build independent of Firefox and has its own settings, profile folder and installation path. As a result, it can be installed alongside Firefox or any other browser. No phoning home — Embedded server links and other calling home functions are removed. In other words, minimal background connections by default. User settings updates Extensions firewall: limit internet access for extensions. Multi-platform (Windows/Linux/Mac/and soon Android) Community-Driven Dark theme (classic and advanced) LibreWolf privacy features: Delete cookies and website data on close. Include only privacy respecting search engines like DuckDuckGo and Searx. Include uBlockOrigin with custom default filter lists, and Tracking Protection in strict mode, to block trackers and ads. Strip tracking elements from URLs, both natively and through uBO. Enable dFPI, also known as Total Cookie Protection. Enable RFP which is part of the Tor Uplift project. RFP is considered the best in class anti-fingerprinting solution, and its goal is to make users look the same and cover as many metrics as possible, in an effort to block fingerprinting techniques. Always display user language as en-US to websites, in order to protect the language used in the browser and in the OS. Disable WebGL, as it is a strong fingerprinting vector. Prevent access to the location services of the OS, and use Mozilla's location API instead of Google's API. Limit ICE candidates generation to a single interface when sharing video or audio during a videoconference. Force DNS and WebRTC inside the proxy, when one is being used. Trim cross-origin referrers, so that they don't include the full URI. Disable link prefetching and speculative connections. Disable disk cache and clear temporary files on close. Disable form autofill. Disable search and form history...and more. LibreWolf 152.0-1 changelog: Upstream release, see the Firefox 152.0 Release Notes Notable changes: The AppImages are now built on Codeberg along with the other releases We have decided to wait a bit longer to enable the settings redesign, due to use being aware of multiple upstream issues Download: LibreWolf 64-bit | Portable 64-bit | ~100.0 MB (Open Source) Download: ARM64 | Portable ARM64 Links: LibreWolf Home Page | Addons | Screenshot | Reddit Get alerted to all of our Software updates on Twitter at @NeowinSoftware
