Stories like this always remind me of bad advice some people give about formatting drives if infected with ransomware and that there's never any hope of recovering data once encrypted.

Microsoft Security Monthly Rollup update for October 2019

https://www.bleepingcomputer.com/news/microsoft/windows-10-cumulative-update-kb4517389-and-kb4519338-released/

One of my users has reported a boot problem today, but the OS is Windows 7, not Windows 10.

As usual, the fix is to run system restore to rollback the update and let the OS to fix the boot problem on its own.

How get data from SQL server in batches and then store it excel.

When we faced an issue while exporting large amount of data in excel.

For this I found a solution where we can get data from SQL server in batches and then store it excel.

Below mentioned is code to get data in the required batch size.

The getData function here returns the required DataTable and the arguments passed are sqlparamaters and the current pageindex.

<----------------------------------------------------Code Begins--------------------------------------------------------------------------------->

int pageindex = 0;

for (int i = 1; i < totalrecords; i = k * batchsize)

{

dt = getData(param, pageindex);

GridView gridView = new GridView();

DataTable dtn = new DataTable();

gridView.DataSource = dt;

gridView.AutoGenerateColumns = true;

gridView.DataBind();

gridView.RenderControl(htmlWriter);

Response.Clear();

Response.Cache.SetCacheability(HttpCacheability.NoCache);

Response.ContentType = "application/vnd.ms-excel";

Response.AddHeader("content-disposition", "attachment;filename=" + filename);

Response.Charset = "";

pageindex ++;

}

htmlWriter.Close();

Response.Write(writer.ToString());

Response.End();

<----------------------------------------------------Code Ends--------------------------------------------------------------------------------->

How to create/Configure Error page in asp.net web application
When any error was occurred into our asp.net web application it is require that client doesn't know about this error. At that time we need to implement error page redirection and the error details are directly sent to Website administrator vie email.

Error Page Creation Steps

Step 1 – Create Global.asax file into your project and write following code into “Application_Error”

void Application_Error(object sender, EventArgs e)

{

HttpUnhandledException httpUnhandledException = new HttpUnhandledException(Server.GetLastError().Message, Server.GetLastError());

Application["Exception"] = HttpContext.Current.Server.GetLastError();

Application["actualerrorpage"] = httpUnhandledException.GetHtmlErrorMessage();

Application["errortime"] = DateTime.Now.ToLocalTime().ToString();

Application["errorurl"] = Request.Url.AbsoluteUri.ToString();

Application["browser"] = Request.Browser.Browser.ToString() + " ( " + Request.Browser.Type.ToString() + " )";

Application["clientip"] = Request.UserHostAddress.ToString();

if (Request.UrlReferrer != null)

{

Application["referurl"] = Request.UrlReferrer.AbsoluteUri.ToString();

}

else

{

Application["referurl"] = "None";

}

}

Step 2 – Create error.aspx page into your website / Project and write following code into your error.aspx.cs file Page_Load event and “MailToSendSite” function outside of the Page_Load event

Did you ever ask yourself "Is someone spying on my screen at work"? This is indeed very easy to do if shadowing, which admins may use for remote control and support, is configured incorrectly. Read my article https://www.experts-exchange.com/articles/33768/Using-RDP-shadowing-for-convenient-user-support-and-remote-control.html

Is shadow present and set to 2?In the registry at Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services, is shadow present and set to 2 or 4? That means, your pc might be setup for shadowing without user consent, which mirrors your screen, without you even knowing it.

I've heard about DEEPFAKE for a little while now, but it seems to be turning into yet another negative use of all the great technology we have at our disposal.  So I guess you can no longer say "it must be true, I saw it on the internet"... :-)

I know a lot of people say Windows Defender is "good enough". So keep this new bug in mind: https://www.bleepingcomputer.com/news/microsoft/windows-defender-antivirus-scans-broken-after-new-update/
The TL;DR info is this: Full and scheduled scan is broken, custom scan still works.

How is this different from any other antivirus?  They all have update bugs from time to time.

My colleague was trying to find a solution to auto-turn on a machine due to the power failure.

I thought the following article is a good start to refer to:

One thing they didn't mention... Although they do recommend purchasing a UPS to protect from power fluctuations, there are other reasons I have experienced. When the power comes back on, it may flicker on and off. I have had this kill a PC because it kept switching on and off. You can avoid this by setting the UPS to not restore power right away. It also keeps the system up through small power blips.

Calculate Quartiles in Microsoft Access


Quartiles
There is no single "correct" calculation method for quartiles. Excel features two methods, some math and statistic packages offer some more, but my latest article presents no less than twenty methods for various purposes using VBA and Microsoft Access.

20 Varieties of Quartiles

The documentation to find is sparse, so comments are most welcome.

Apparently United Rentals email was hacked, as opposed to someone spoofing email from their domain. They are a large company, so heads up if you have business dealings with them.

Cybersecurity Bulletin

United Rentals
(Aug 22, 2019)
 
The email system for United Rentals was hacked Aug 21, and several of our employees have reported getting the email. The attack was real with the intent to access our systems by having users click on the links.  
 
Key Red Flags:
-      External Email
-      Invoice number missing in email body
-      Misleading links (use of wvw instead of www at the front of the links)
-      Links with several characters and numbers
-      Request for payment
-      No formal title for employee sending email (only shows Sales)
