Cyber security (hypothetical) questions.

Encryption is pretty unbreakable these days. However there’s a market is stealing encrypted data as with quantum computers it’s only a matter or a few years before it becomes crackable. So stealing detailed plans for critical infrastructure will be an issue if in 5 years when it’s still operational, other nations have access to it.

As for the op I doubt there’s much of a market for code or any intellectual property. Hacking generally is for information eg state secrets, credit card info, personal data etc.
A software engineer could possibly keep encryption keys secret as getting those might unlock the software which contains critical information. But I very much doubt such keys would be kept in the cloud where any Dropbox engineer could potentially read it.

Thanks for all the great answers, think I've got enough to work with, probably go for a physical break in and an external hard drive copied to to the thiefs laptop. not sure when I want the owner to know! perhaps quite late in the book. it is going to a strange/weird book but has to be real stuff needs to be grounded in fact (a bit)

Physical break in, hacker has been watching the coder for weeks and knows that he goes off to make a sandwich at 12ish leaving his laptop unlocked

I sort of see where you are coming from, but you are so wrong. :smile:

It is tempting to look at a web site and say that it took a week to create.

A real desktop application such as Excel Version 1 might have taken a year or two write and the current Version of Excel would probably take twenty man years plus if you were to start from scratch.

I appreciate that the code below is compiler version dependent but it is so much faster than the code the compiler generated from C++ code it was worth this dependency.

C++:

void CIBViewApp::CGDCountxy(void)
{
// Count for for fields
// data saved as <x1><y1>,<x1><y2>,<x1><y3>,<x2><y1>,<x2><y2> etc or

    int *ipuse, *xp, cox,coy,xlen, strskip;
    int xdateoffset, ydateoffset;    // Data and date types
    int idxx, idxy;                        // Index into the results buffer
    char *cp, *cp2, offsetv;
    void *xptr, *yptr;

    // Read this views list
    cp = DataChainStart[theCurrentView->BufferNumber];

    // Next row pointer
    offsetv = (theCurrentView->BufferNumber + 1) * SO_charp;

    // Offset to the index not the value
    cox = CalcingColOffset[0];coy = CalcingColOffset[1];

    // set the pointers for the x data types
    switch (DataColType[theCurrentView->GraphCol[0].DataColNum])
    {

And how many counterfeit applications are there out there? How many counterfeit versions of office or Adobe software or operating systems are there? Hackers don’t steal Office source code they create patches to bypass the security to run the original application or steal passwords to open user files which contains information they find valuable.

Good afternoon,

I sort of see where you are coming from, but you are so wrong.

No he wasn't.

It is tempting to look at a web site and say that it took a week to create.

A real desktop application such as Excel Version 1 might have taken a year or two write and the current Version of Excel would probably take twenty man years plus if you were to start from scratch.

Very true, but so what?

The fact it takes that much effort doesn't mean somebody who can hack into the servers is going to steal the partly written code.

When code is hacked, the hackers are almost always just looking for ways to get regitration details so they can sell they keys. For that, they don't want part-completed code they can then "finish".

I would be very surprised if the total number of times somebody has stolen commercially useful part-written code and then completed it needs any more than thumbs to count.

I appreciate that the code below is compiler version dependent but it is so much faster than the code the compiler generated from C++ code it was worth this dependency.

That you probably don't understand the above is the point , the stuff below is pretty self explanatory.

Not too sure what you think the relevance of quoting code snippets was.

Sure, it takes efvort to write useable code. It takes almost as much to understand somebody else's code unless they have been much better than average at including comments.

But neither of those facts have any real relevance to the likelihood of part-written code being copied and completed.

Fully complete code, slightly more likely, so that the copier can then modify the access restrictions, and sell the pirated version, having made only relatively trivial changes.

Physical break in, hacker has been watching the coder for weeks and knows that he goes off to make a sandwich at 12ish leaving his laptop unlocked

strangely enough this could be perfect idea as the hacker knows for certain reasons when the owner is having his lunch... but the reader wont know why until the end of the book

Encryption is pretty unbreakable these days. However there’s a market is stealing encrypted data as with quantum computers it’s only a matter or a few years before it becomes crackable. So stealing detailed plans for critical infrastructure will be an issue if in 5 years when it’s still operational, other nations have access to it.

That relies on also having the public key information. If you don’t have that, then you are pissing in the wind even with quantum and Shor’s algorithm as there’s nothing to factorize.

In most cases, not really.

It certainly can be truly public, but you will more commonly only give even the public key to people you would have a reasonable expectation will need access.

Software development is my living, and I’ve done it both freelance and direct hire.

These days, the typical “backup” is to a version control repository such as GitHub or Bitbucket which are cloud-based, and very secure. Developers will typically work on a “branch” of the production version of the software, and then “commit” their work to that branch. When the work is ready, the developer makes a “pull request” and, after the lead developer reviews the work, it’s either merged into production (or an intermediate step, usually called “staging”) or sent back to the developer for correction.

Concerning the matter of detecting a hack: That’s a pretty thorny one. A well organized software operation will have a suite of tests to make sure that the software does what it’s designed to do, but these could be hacked to give false results. One glaring example of this process failing was the recent Solarwinds hack that caused a bogus version of this security software to be distributed to government and private sector systems.

If you’d like to have a Q&A on this with me, I’d be happy to help.

Thanks I may take you up on the offer of Q&A when i get to relevant sections. sounds your work is exactly what my character does!
