Why Copilot Access to “Restricted” Passwords Isn’t as Big an Issue as Uploading Files to ChatGPT
Unless You Consider Excel Passwords to be Real Passwords
I see that some web sites have picked up the penetration test story about using Microsoft 365 Copilot to extract sensitive information from SharePoint. The May 14 Forbes.com story is an example. The headline of “New Warning — Microsoft Copilot AI Can Access Restricted Passwords” is highly misleading.
Unfortunately, tech journalists and others can rush to comment without thinking an issue through, and that’s what I fear has happened in many of the remarks I see in places like LinkedIn discussions. People assume that a much greater problem exists when if they would only think things through, they’d see the holes in the case being presented.
Understanding the Assumptions made by the Penetration Test
As I pointed out in a May 12 article, the penetration test was interesting (and did demonstrate just how weak Excel passwords are). However, the story depends on three major assumptions:
- Compromise: The attacker has control of an Entra ID account with a Microsoft 365 Copilot license. In other words, the target tenant is compromised. In terms of closing off holes for attackers to exploit, preventing access is the biggest problem in the scenario. All user accounts should be protected with strong multifactor authentication like the Microsoft authenticator app, passkeys, or FIDO-2 keys. SMS is not sufficient, and basic authentication (just passwords) is just madness.
- Poor tenant management: Once inside a tenant and using a compromised account, Microsoft 365 Copilot will do what the attacker asks it to do, including finding sensitive information like a file containing passwords. However, Copilot cannot find information that is unavailable to the signed-in user. If the tenant’s SharePoint Online deployment is badly managed without well-planned and well-managed access controls, then Copilot will happily find anything that the user’s access allows it to uncover. This is not a problem for Copilot: it is a failure of tenant management that builds on the first failure to protect user accounts appropriately.
- Failure to deploy available tools: Even in the best-managed SharePoint Online deployment, users can make mistakes when configuring access, Users can also follow poor practice, such as storing important files in OneDrive for Business rather than SharePoint Online. But tenants with Microsoft 365 Copilot licenses can mitigate against user error with tools available to them such as Restricted Content Discovery (RCD) and the DLP policy for Microsoft 365 Copilot. The latter requires the tenant to deploy sensitivity labels too, but that’s part of the effort required to protect confidential and sensitive information.
I’m sure any attacker would love to find an easily-compromised tenant where they can gain control over accounts that have access to both badly managed SharePoint Online sites that hold sensitive information and Microsoft 365 Copilot to help the attackers find that information. Badly-managed and easily-compromised Microsoft 365 tenants do exist, but it is my earnest hope that companies who invest in Microsoft 365 Copilot have the common sense to manage their tenants properly.
Uploading SharePoint and OneDrive Files to ChatGPT
Personally speaking, I’m much more concerned about users uploaded sensitive or confidential information to OpenAI for ChatGPT to process. The latest advice from OpenAI is how the process works for their Deep Research product. Users might like this feature because they can have their documents processed by AI. However, tenant administrators and anyone concerned with security or compliance might have a different perspective.
I covered the topic of uploading SharePoint and OneDrive files to ChatGPT on March 26 and explained that the process depends on an enterprise Entra ID app (with app id e0476654-c1d5-430b-ab80-70cbd947616a) to gain access to user files. Deep Research is different and its connector for SharePoint and OneDrive is in preview, but the basic principle is the same: a Graph-based app uploads files for ChatGPT to process. If that app is blocked (see my article to find out how) or denied access to the Graph permission needed to access files, the upload process doesn’t work.
Set Your Priorities
I suggest that it’s more important to block uploading of files from a tenant to a third-party AI service where you don’t know how the files are managed or retained. It certainly seems like a more pressing need than worrying about the potential of an attacker using Microsoft 365 Copilot to run riot over SharePoint, even if a penetration test company says that this can happen (purely as a public service, and not at all to publicize their company).
At least, that’s assuming user accounts are protected with strong multifactor authentication…
Is it possible to make this tiny loop faster?
It seems that it might be possible to make this loop faster. Does anyone have any thoughts? I have to call a loop like this millions of times in a larger workflow, and it is getting to be the slowest part of the code. I appreciate any insights!

TIFF from ImageJ not loading correctly in R2024b (worked in R2022b)
Hi,
I’ve been using MATLAB to analyze 3D confocal images saved as TIFF files. My process is to get the original images from NIS-Elements, then open them in ImageJ to crop just the droplet region, and save that as a TIFF. In MATLAB R2022b, this TIFF input would allow the program to do a full 3D reconstruction of the droplet and calculate the data I need.
But now that I’m using R2024b, the same TIFF files don’t load properly. The 3D reconstruction step stops and doesn’t work, and I get no data even when I test it using the exact same TIFF files and inputs that worked previously.
I’m wondering if MATLAB R2024b handles TIFF files differently than R2022b? Are there specific settings I should use when saving TIFFs from ImageJ to make sure they work with the latest MATLAB? Or would this be entirely a different problem?

Regarding using trainnet, testnet in binary image classification(size difference between network output and test data output)
Hello, every MATLAB users,
I’m trying to make simple binary classification network
model is designed to check whether the image has certain object or not
input datastore is combined of image datastore and label datastore as shown:
imdsTrain = imageDatastore(trainingDataTbl.imageFileName);
imdsTrain.Labels = trainingDataTbl.existence;
imdsTrain.Labels = categorical(imdsTrain.Labels)
labelsTrain = categorical(trainingDataTbl.existence);
ldsTrain = arrayDatastore(labelsTrain);
cdsTrain = combine(imdsTrain, ldsTrain);
(i know already imdsTrain has label data but i modified to debug the error even it doesn’t matter)
Each labels is one of 2 categories : True, False
Designed network structure is as follows:
fcn = @(X) X(:,:,1);
bClayers = [
imageInputLayer([800 800 3],"Name","imageinput")
functionLayer(fcn, "Name","gray")
convolution2dLayer([5 5],8,"Name","conv","Padding","same")
reluLayer("Name","relu")
maxPooling2dLayer([8 8],"Name","maxpool","Padding","same","Stride",[8 8])

reluLayer("Name","relu_1")
maxPooling2dLayer([5 5],"Name","maxpool_1","Padding","same","Stride",[5 5])

CheckpointPath=tempdir);
I set the MiniBatchSize with 1.
Because, I don’t know why but some reason error came up when i execute the trainnet function.
net = trainnet(cdsTrain, bClayers, "crossentropy", options);
the error message is that size of prediction(maybe output of the network) is not same with size of desired value(maybe ground truth label data).
and the desired value size is affected by MiniBatchSize.
I have no idea why this error is occuring.
How Can I Adjust MiniBatchSize or Modify the Code to Run Succesfully??

Microsoft 365 Copilot Gets Viva Insights Service Plans
Two Workplace Analytics Service Plans to Enable Viva Insights
Microsoft message center notification MC1009917 (last updated 25 April 2025, Microsoft 365 roadmap item 471002) announced the inclusion of Viva Insights in the Microsoft 365 Copilot license. The mechanism used is the addition of two “Workplace Analytics” service plans to join the existing eight service plans (table 1) that make up the Copilot license.

Table 1: Microsoft 365 Copilot Service Plans
The last update from Microsoft said that updates to add the Viva Insights service plans completed in mid-April 2025.
Viva Insights and Microsoft 365 Copilot
According to Microsoft, access to Workplace Analytics allows “IT admins and analysts can tailor advanced prebuilt Copilot reports with their business data or create custom reports with organizational attributes, expanded Microsoft 365 Copilot usage metrics, and more granular controls.” The data is exposed in Viva Insights (web), the Viva Insights Teams app (Figure 1), and the Viva Insights mobile apps.
Everyone running a Copilot deployment is intimately aware of the need to track and understand how people use AI in different apps. The API behind the Copilot usage report in the Microsoft 365 admin center delivers sparse information. It’s possible to enhance the usage report data with audit data and use the result to track down people who don’t make use of expensive licenses, but that requires custom code. Hence the insights reported in the Copilot Dashboard in Viva Insights.
A note in the announcement says that access to the Copilot Dashboard now requires a minimum of 50 Viva Insights (Copilot) licenses. As obvious from Figure 1, my tenant has fewer than 50 licenses, but can still use Viva Insights because it’s not a new tenant.
What Service Plans Do
As you’re probably aware, a license (product, or SKU) is something that Microsoft sells to customers. A service plan enables or disables specific functionality within a license. For example, the Copilot license includes the Copilot Studio in Copilot for Microsoft 365 service plan, which in turn allows users to create agents in Copilot Studio. If you don’t want people to be able to access Copilot Studio, you can disable the service plan.
Disabling a service plan can be done by updating a user’s licenses through the Microsoft 365 admin center. Options are available to do this through User Accounts or License Details (Figure 2).
If you use group-based licensing, you can amend the options for the Copilot license to remove service plans. However, this affects every user in the group, so you might end up with one group to assign “full” Copilot licenses and another to assign “restricted” licenses.
Be Careful When Disabling Copilot Service Plans
One potential issue with some Copilot service plans is that you’re never quite sure what removing a service plan will do. Removing the Microsoft 365 Copilot in Productivity Apps service plan seems straightforward because it disables the Copilot options in the Office desktop apps (all platforms). But disabling the Intelligent Search service plan will mess up any app that uses Copilot to search.
Blocking Copilot Studio is problematic. Removing the service plan only removes the ability of a user to sign in to use Copilot Studio. They can still sign in for a 60-day trial, just like anyone else with an email address who doesn’t have a Copilot Studio license.
Disabling Copilot Service Plans with PowerShell
Disabling service plans through a GUI can rapidly become tiresome. I wrote a PowerShell script to (downloadable from GitHub) to demonstrate how to use the Set-MgUserLicense cmdlet from the Microsoft Graph PowerShell SDK to disable a Copilot service plan. Another variation on removing service plans is explained here.
The script checks for group-based license assignment for Copilot licenses and if found, creates an array of excluded accounts that it won’t process. It then scans for accounts with a Microsoft 365 Copilot license and if the account isn’t excluded, runs Set-MgUserLicense to disable the Copilot Studio service plan. It’s just an example of using PowerShell to automate a license management operation and is easily amended to process any of the Copilot service plans. Enjoy!!

Optimal decimation to Log Simulation Data
Hello everyone,
I have a Inverter model and I want to calculate its switching losses, although I can use MATLAB function ee_getPowerLossSummary, but I want to implement my own power loss analysis in post-processing. If I modulate the inverter at 5kHz, the switching event happens every 200mcicrosecond, and if I want to log simulation data in workspace, what should be the decimation keeping in mind these things.
I am using a variable step solver, because I couldn’t use fixed step with N-channel MOSFTET, where PWM is provided by the Three-phase Two-Level PWM generator with sample time (1/10*Fsw).
If I run the simulation for 7 seconds only, the total step sizes could be up to 7M, keeping in mind the step size of 1microsecond.
Is there any way to run that model with fixed-step solver, or what should be the decimation so that my simulation speed is optimal as well as I can capture the swiching events.
Looking forward to hearign from the experts.

I need to use a scope to display the current i and the power P as functions of the voltage V, with the curves obtained for various irradiance levels and temperatures
1. Context
As part of my energy modeling project, I developed a simulation model in Simulink:
A photovoltaic (PV) panel model based on the single-diode approach, accounting for irradiance and temperature effects.
the model generate time-domain outputs under standard test conditions.
2. Objectives
I need to extract the I–V and P–V curves of the PV panel for different environmental conditions:
Irradiance (G): 200, 400, 600, 800, 1000 W/m²
Temperature (T): 0°C, 25°C, 50°C
3. Current model status

External Mode Connection Issue with C2000 LaunchPad and Speedgoat System
Dear MathWorks Support Team,
I am reaching out to request your assistance with an issue we are facing during the implementation of a controller model using the C2000 Blockset. As advised by Speedgoat support, this problem appears to be related to the C2000 Blockset, and they have recommended that we consult you directly.
Project Setup Overview:
We are working with two models:
Plant model – implemented on the Speedgoat FPGA
Controller model – implemented on a LaunchPad development kit (https://www.speedgoat.com/products/launchpad-development-kit) (TI LaunchXL-F28379D)
The two systems communicate via analog signals using the IO334 interface.
We have successfully confirmed the following:
The plant model is transmitting correct signals to the LaunchPad, verified using an oscilloscope via SMA connectors on the LaunchPad.
The LaunchPad receives the input signals correctly.
The plant model is also responding correctly when tested with a signal generator.
Issue Description:
The controller model builds, deploys, and starts successfully on the LaunchPad. However, when we attempt to use Monitor & Tune (external mode), we encounter the following error:
"External Mode Open Protocol Connect command failed: Could not connect to target application. XCP internal error: timeout expired."
We have attached relevant screenshots and the build report for your review.
Setup Details:
The LaunchPad is connected to the PC via USB.
It is also connected to the Speedgoat system via the SAMTEC connector.
We have used the blocks recommended in the documentation for the LaunchPad.
We would greatly appreciate your help in identifying the cause of this issue and guiding us through any additional steps or configurations needed to enable external mode communication.
Thank you very much for your support.

how to validate mscohere?
I would like to validate the use of mscohere for impact test data, using an instrumented hammer that measures force and an accelerometer to measure response. I ran some artificial cases – see attached pdf. Single input, single output. I tried to force mscohere to use only 3 windows of data, one for each impact test. The first half of results are for sinusoidal input and output, and the second half are for a simulated impact input. There are 2 time domain plots in there. The inputs are the 3 input vectors stacked vertically, and the 3 output vectors stacked vertically. Sample rate is 1000 Hz, with a 4 second window and 0.25 Hz resolution. I am using a rectangular window:
[coherence, frequencies2] = mscohere(coherenceInput, coherenceOutput, rectwin(windowLength), 0, windowLength, sampleRateHz);
The results look about right to me, but I would like to validate it against some known or anlytical results. Are there any suitable examples available?

S curve ramp function
I need help creating a function for an s curve ramp. The code below will create the inserted picture below. However, this code only works for a constant ramp block (connected to x). This code from the piecewise function on the Matlab smf() help file page.
I need two additional inputs (acceleration rate and jerk rate). The output should ramp the input velocity (x) signal based on the acceleration rate (a), and jerk rate (j). I need the block or code to be dynamic. I do not want to put a time value inside of my code. I will be exporting the code to structure text and input the code into a Siemens PLC.
I don’t want to include a fixed dt in my code because I will be running the code in a PLC. Maybe it would be better to design this function in simulink and set a fixed time solver and use integrator blocks?

m = (a + b)/2;
y = (x > a & x <= m) .* ( 2*((x-a)/(b-a)).^2) + …
(x > m & x <= b) .* (1-2*((x-b)/(b-a)).^2) + …
(x > b);
endI need help creating a function for an s curve ramp. The code below will create the inserted picture below. However, this code only works for a constant ramp block (connected to x). This code from the piecewise function on the Matlab smf() help file page.
I need two additional inputs (acceleration rate and jerk rate). The output should ramp the input velocity (x) signal based on the acceleration rate (a), and jerk rate (j). I need the block or code to be dynamic. I do not want to put a time value inside of my code. I will be exporting the code to structure text and input the code into a Siemens PLC.
I don’t want to include a fixed dt in my code because I will be running the code in a PLC. Maybe it would be better to design this function in simulink and set a fixed time solver and use integrator blocks?
x = 0:0.01:10; % domain
a = 1; % unsaturated interval’s left endpoint
b = 8; % unsaturated interval’s right endpoint
y = smf(x, a, b);
plot(x, y), grid on
xline(a, ‘–‘)
xline(b, ‘–‘)

xlabel("x")
ylabel("Amplitude")
ylim([-0.05 1.05])

How to express constants of integral
Hi everyone,
I am a matlab beginner. How can I find the constants of integral C1 and C2 ?
For example i know that, how can i find constants of integral C1 and C2 in this script? Thanks 🙂
syms x
y1 = exp(-2*x+sqrt(6)*x);
y2 = exp(-2*x-sqrt(6)*x);
g = 2*x^2-3*x+6;
A = [y1 y2;diff(y1,x) diff(y2,x)]
b = [0; g]
Ab
u = simplify(Ab)
u = int(u,x)

I want to build a double pendulum system in Simulink but am getting errors relating to the tolerance and step size
How do I solve this coupled second order differential equation.
Errors:
Right now it uses ode45 to solve it but I have tried every model, added the memory block, changed the initial conditions to be smaller, changed the max step size and relative errors but nothing works.How do I solve this coupled second order differential equation.
