QUESTION
I create a Pentest tool for educational purposes, so the old version was written using python 2, then I convert it to python 3 and when I try to run the main file pxxtf.py I got multiple errors, I correct most of them but for this one about Circular Import, I try multiple fixes from forums and StackOverFlow and nothing work with me.
When I try to run the main script :

So I've been trying to create an anti-exploit system, but one that can't be disabled via exploits. and when I try to see if any of the Humanoid's attributes changing, by using (function param1).Character.Humanoid I get an error in the developer console (in game, not below the command line) showing attempt to index nil with humanoid

...ANSWER
Answered 2021-May-10 at 07:03Why do you expect p.Character to be anything but nil?
From the Roblox manual:
Character
... Initially, this property is nil then set when the player’s character first spawns. Use the Player.CharacterAdded event to detect when a player’s character properly loads
When a player is added it does not have a Character yet. Also running that in an infinite loop that never breaks, even after the player has been kicked doesn't make too much sense to me.
QUESTION
I wonder if it is possible to run code provided by users in a webpage in a safe way.
I would like to add code that users can dynamically change to change some of the page behaviour, but I don´t want them to use exploits.
For example, I would like to let the users write a method returning a boolean in a safe way so they do not inject malicious code in the page and alter the dom nor steal info of the rest of the components in the page.
...ANSWER
Answered 2021-May-12 at 11:11As long as users only run their own code, there's no need for any security measures. If they break the site, they break it only for themselves.
If these codes are going to be shared, the only reliable way is to have an sandboxed IFRAME and run everything in there (look at how SO snippets, JS fiddle and similar sites work). In this case, user scripts won't be able to interact with the main page though. Here's a good article on the topic: https://www.html5rocks.com/en/tutorials/security/sandboxed-iframes/
If you need userscripts that 1) can interact with the main page AND 2) can be shared between users, then you have to invent your own programming language and compile it to javascript on the fly. There's no option in JS to sandbox the built-in eval.
QUESTION
Goal: I want compare two Suricata rule files and comment out the same lines (alerts "SIDs") from file1 in file2 unless it already commented out. I understand there is better way to do this with the Suricata threshold file but I unfortunately don't have that luxury beyond what I can explain here. This is to facilitate updating the rules where the rule may get updated but the commonality the "SID" will be the same across both files.
I'm not sure where to start.

QUESTION
I have not, but shall DAST* security test, out of curiosity, an IoT device; Nodemcu esp8266 www server I built. It's showing a HTML page (on a mobile phone for example) that allows to control and interact with a camera module and a A/C relay. With it I can for example show images captured in the camera I even think it has some image recognition built in, and I can switch on and off a relay for electrical current to a light bulb (110/220v A/C power)
Before I start pentest I though I better start thinking of what types of exploits one would be able to find and detect? Which sinister exploits I will be able to find, or rather ought be able to find given a proper pentest exercise? (And if I do not find exploits, my approach to the pentest of the Iot might be wrong)
I ponder it might be a totally pointless exercise since the esp8266 www server (or rather its LUA programming libraries) might not have any security built into it, so basically it is "open doors" and everything with it is unsafe ?
The test report might just conclude what I can foresee be that the the "user input needs to be sanitized"?
Anyone have any idea what such pentest of a generic IoT device generally reports? Maybe it is possible to crash or reset the IoT device? Buffer overruns, XXS, call own code ?
I might use ZAP or Burpsuite or similar DAST security test tool.
- I could of course SAST test it instead, or too, but I think it will be hard to find a static code analyzer for the NodeMCU libraries and NUA scripting language easily ? I found some references here though: https://ieeexplore.ieee.org/abstract/document/8227299 but it seems to be a long read.
So if someone just have a short answer what to expect in a DAST scan/pentest , it would be much appreciated.

...ANSWER
Answered 2021-Apr-08 at 01:04I do my vulnerability scanning with OpenVAS (I assume this is what you mean by pentesting?). I am not aware of any IOT focused Tools.
If your server is running on esp8266, i would imagine that there is no much room for authentication and encryption of http traffic, but correct me if i am wrong).
Vulnerability Scan results might show things like unencrypted http traffic, credentials transmitted in cleartext (if you have any credentials fields in the pages served by the web server) etc. Depending on if there is encryption, you might also see weak encryption findings.
You might get some false positives on your lua webserver reacting like other known webservers when exploits are applied. I have seen this kind of false positive specially on DoS vulnerabilities when a vulnerability scan is testing a vulnerability and the server becomes unresponsive. Depending on how invasive your vulnerability scanner is, you might get a lot of false positives for DoS on such a constrained platform.

self.contents = ''
def content_callback(self, buf):
self.contents = self.contents + buf
def exploitdb_search(name):
if len(name) != 0:
query = str(name) + ' ' + 'site:https://www.exploit-db.com/'
for data in search(query, num_results=1):
if "https://www.exploit-db.com/exploits" in data:
x = ContentCallback()
c = pycurl.Curl()
c.setopt(c.URL, '{}'.format(data))
c.setopt(c.WRITEFUNCTION, x.content_callback(data))
c.perform()
c.close()
print(t.content)
ANSWER
Answered 2021-Mar-04 at 23:52The value of the c.WRITEFUNCTION option should be a function. You're passing the result of calling the function, which is None because content_callback() doesn't return anything. Setting the option to None is interpreted as trying to unset the option, which isn't allowed for this option.
You should take off the argument list to the function so that you pass a reference to the function.
QUESTION
I want to add all nonzero elements from a numpy array arr to a list out_list. Previous research suggests that for numpy arrays, using np.nonzero is most efficient. (My own benchmark below actually suggests it can be slightly improved using np.delete).
However, in my case I want my output to be a list, because I am combining many arrays for which I don't know the number of nonzero elements (so I can't effectively preallocate a numpy array for them). Hence, I was wondering whether there are some synergies that can be exploited to speed up the process. While my naive list comprehension approach is much slower than the pure numpy approach, I got some promising results combining list comprehension with numba.
Here's what I found so far:
...ANSWER
Answered 2021-Feb-28 at 02:13Instead of extending a list by all of the elements of a new array, append the array itself. This will make for much fewer and smaller reallocations. You can also pre-allocate a list of Nones up-front or even use an object array, if you have an upper bound on the number of arrays you will process.
When you're done, call np.concatenate on the list.
So instead of this:
QUESTION
I am writing an implementation of Bridson's Poisson disc sampling (https://www.cs.ubc.ca/~rbridson/docs/bridson-siggraph07-poissondisk.pdf) for Python.
A feature of this sampling is that there is a set minimal distance between samples, and it avoids clustering. The neighbour lookup for new candidate points exploits this feature, and uses a background grid to speed up searches.
The background grid consists of a boolean grid M that stores True for non-empty cells and False otherwise, and a grid of points P that stores the exact coordinates. Both of them are implemented as n-dimensional numpy arrays.
The grid size cellsize is selected in such a way that there is at most one sample in each grid cell, and then you only have to check a few of the nearest rows and columns.
For now, I use the following procedure for checking if the point p is close to any of the existing points:
ANSWER
Answered 2021-Feb-06 at 09:22The dimensionality makes it a bit tricky. In the end, the overhead for preparing the sliced into an array was well worth it. Maybe a further optimization would be possible if you knew the dimensions beforehands. It shouldn't be too much of a difference. As an interesting part, this made the M matrix almost redundant - it is only used to check if the point itself is worth the try since the rest of the multiplication is sped up drastically by the slice.
Update:I re-introduced the M check as per comment and also used the np.square instead of np.power as op mentioned.
Time after the np.power > np.square transition:
