Strange Proxy Application Behavior on iOS 13.5.1

Background: My buddy is a freelance journalist working on a story on one of the bigger software companies (a household name, starts with an A). Anyway, he asked me to take a look at his iPad because while he’s versed in InfoSec, this may be outside of his scope.

While examining the iPad I noticed that:

Entries seem to be selectively disappearing from the SSL enabled Charles iOS application.

Using the proxy I set up a block list of all Apple hostnames (Apple, iTunes, iCloud, iPhone.com) with wildcards. However, iMessage texts seem to be getting through with no issue, while last week text messages via iCloud were effectively blocked. It seems that the proxy behavior effectively changed.

Here is a video capture of an entry disappearing where you can see an entry disappear at the 13 second mark : https://youtu.be/E2loM_F0TVQ

Using another firewall, I also noticed that certain actions triggered https calls that don’t appear while Charles is enabled. Which suggests that the proxy is selectively printing certain connections and not others.

Even more bizarre, screen recordings and screenshots that I’ve taken on the iPad while observing non-normative network activity seem to have been mysteriously corrupted and unusable.

My question is a) whether anyone has observed this behavior with Charles before and b) how would I go about identifying a potential compromise on a device potentially facilitated/enabled by the manufacture? We’re considering this possibility because he may be a high value target because of his story and everything on his device is locked down extremely tight. I even factory reset the device, removed every stock application I could and installed no new apps except for the proxy and observed the same behavior.

troubleshooting – What are these strange lines on images from my Fujifilm FinePix F850EXR?

The pattern does look like moire and it is incredibly symmetrical. Is the symmetry typical of other affected shots? If so, that rules out optical imperfections. I am willing to bet the problem is electronic.

There is a way to tell if it’s the sensor. When you say it looks fine “when simply looking through the lens” I assume you are looking at the display on the back of the camera, so obviously its still going through the sensor. Does it look the same on the back display after you’ve taken the shot? If not then the sensor isn’t to blame, its the electronic processing or the storage that is the issue (you say you ruled out storage). If it does look the same, then you know you captured the picture accurately, (assuming its not just because the pattern is too small to see, but then again there is also discoloration which should be detectable even on the smallish display).

Is the distortion only evident after downloading the image from the camera? Perhaps there is a problem with the transfer method?

From what you’ve described, I am tempted to think that the problem is in the image processing chip.

centos – Strange Postgresql behaviour on start

Centos 8.3, postgresql 12 (i tried even 10, same thing). I have set
the permission of the data directory as postgres:postgres. if i start
the service from systemctl, it gives me “creation of lock file
“postmaster.pid” failed: Permission denied”. if i copy the command
from postgresql.service (postmaster -D /data/pgdata) and i run from
the console as postgres user, it works, and the postmaster.pid is
correctly created. I have no ideas, because it’s not a permission
problem…

thank you in advance

display – In videos and images, strange color streaks on one monitor in Windows 10

I just did a clean install of Windows 10 (May 2020 Update).

Now, on one monitor only (I have a two-monitor setup), I see strange color streaks in some videos and images (Netflix, PHPStorm load screen, and others).

I see the issues on a BenQ BL3201PT.

For example, this:

color streak example

What I did so far

  • Reset all the settings on the monitor (in the monitor’s menu).
  • Calibrated the display using the built-in Windows tool.
  • Updated to the latest graphics driver (using NVidia GTX 1070).
  • Unplugged the display and plugged it back in.

Also, I noticed that opening Flux makes the problem worse.

Since I was using Windows 10 on this exact same machine prior to the clean install without this issue, I’m confident it’s software-related, but I don’t know where to go to debug fruther.

c++ – I am getting a very strange error in a memory bandwidth test

I am measuring a higher memory bandwidth for my type of cpu than specified by ark.intel

My type of CPU: i7-8750h

My RAM configuration is 2 slots of 8 GB at 2666 MHz.

The source code for the benchmark: Memory-Bandwidth-Test

Results for my system:

N=6
read or write? (r/w) r
.
.
.
Average time: 60.7056 ms
Average memory bandwidth: 98.8376 GB/s

Maximum theoretical bandwidth should be:

2.666E9 (Transaction/s)* 2 (double data rate)* 64 (bits/Transaction)/ 8 (bits/byte)/ 2^30 (bytes/GB) = 39.72 GB/s

which is close to Intel’s specification of

41.8 GB/s

nowhere near 98.9 GB/s

What am I missing?

networking – Danted on Debian creates strange listening port

I installed danted v1.4.2 on Debian 10 (buster) and I observe danted created few raw sockets and uses them for some purposes. The ss -f inet -an output looks the following way:

Netid   State    Recv-Q   Send-Q   Local Address:Port   Peer Address:Port    
???     UNCONN   0        0              0.0.0.0:1           0.0.0.0:*
???     UNCONN   0        0              0.0.0.0:1           0.0.0.0:*
(MORE UNRELATED DATA)

If I use old school netstat -an, I see “raw” where ss prints “???”. All the rest is identical. BTW, netstat prints state of the sockets as 7, while ss says it is UNCONN.

I spent quite a few hours googling for this behavior, but did not get any results. Danted works and forwards traffic as expected. The only thing is few raw sockets. The biggest issue with these raw sockets is their listening address. As I understand, they configured to listen on port 1 on all interfaces I have on my experimental server. Per my understanding, this is a security breach, since anyone could try to connect to it and I don’t have any good idea how to protect it.

  • Is this some error in danted configuration?
  • If not, is there any way to protect these ports from malicious connect attempts?
  • If answer on second question is yes, then – how?
