Finally a paper on malware fuzzing! PFUZZER: Practical, Sound, and Effective Multi-path Analysis of
Environment-sensitive Malware with Coverage-guided Fuzzing https://www.diag.uniroma1.it/~delia/papers/eurosp25-pfuzzer.pdf

When old Soviet Union jokes are applicable to the US, you know something has gone terribly wrong.

The reason I get so annoyed about people pitching LLMs as a way to 'democratise programming' or as end-user programming tools is that they solve the wrong problem.

The hard part of programming is not writing code. It's unambiguously expressing your problem and desired solution. Imagine if LLMs were perfect programmers. All you have to do is write a requirements document and they turn it into a working program. Amazing, right? Well, not if you've ever seen what most people write in a requirements document or seen the output when a team of good programmers works from a requirements document.

The most popular end-user programming language in the world (and, by extension, the most popular programming language), with over a billion users, is the Calc language that is embedded in Excel. It is not popular because it's a good language. Calc is a terrible programming language by pretty much any metric. It's popular because Excel (which is also a terrible spreadsheet, but that's a different rant) is basically a visual debugger and a reactive programming environment. Every temporary value in an Excel program is inspectable and it's trivial to write additional debug expressions that are automatically updated when the values that they're observing change.

Much as I detest it as a spreadsheet, Excel is probably the best debugger that I have ever used, including Lisp and Smalltalk.

The thing that makes end-user programming easy in Excel is not that it's easy to write code, it's that it's easy to see what the code is doing and understand why it's doing the wrong thing. If you replace this with an LLM that generates Python, and the Python program is wrong, how does a normal non-Python-programming human debug it? They try asking the LLM, but it doesn't actually understand the Python so it will often send them down odd rabbit holes. In contrast, every intermediate step in an Excel / Calc program is visible. Every single intermediate value is introspectable. Adding extra sanity checks (such as 'does money leaving the account equal the money paid to suppliers?') is trivial.

If you want to democratise programming, build better debuggers, don't build tools that rapidly generate code that's hard to debug.

Researchers at Harvard Business School and University of Toronto used unique data to quantify the value of open source.

Takeways:

* Supply-side (cost to recreate) is ~$4.15B, but demand-side (value to firms) is $8.8T. Shows massive cost savings & productivity boost from OSS.

* If OSS didn't exist, firms would need to spend an estimated 3.5 times more on software than they currently do. OSS provides a massive, often invisible, productivity boost.

* A tiny fraction of OSS developers create the vast majority of value. Only 5% of developers are responsible for over 96% of the demand-side value

* Firms should not just "free ride" on OSS but actively contribute to the ecosystem, as this is far cheaper than recreating the software themselves.

does anyone know why my Rust is doing this

Stardew Valley but it's the South Bronx 1960s, you run a community garden & Jojamart is Robert Moses with the Cross Bronx Expressway.

@noopwafel I just saw this. 1) congrats! 🎉 2) that cover is hilarious 😂

@eslerm @bagder Only clarification I would add is that I looked at static analysis bugs, not vulnerabilities, in correlation to a bunch of other metrics. It's not a given that static analysis bugs will correlate with vulnerabilities. Hard to measure vulnerabilities in an objective way (I would not consider CVEs objective for example). I think it's still reasonable to assume projects that are unreadable, complex and buggy to be more vulnerable.

Perhaps even worse, even if you ask clang to produce a compiler warning for the undefined behavior with -Wnull-dereference you get nothing. At least gcc still does the right thing there:

The solution was: Nothing! It turns out that due to the undefined behavior of the NULL-pointer dereference in the beginning of main, clang's optimizer removes main entirely and you just get a call to _fini! No compile time warning, no runtime warning. All is fine in the land of C! 😜

@gparker Haha I guess I haven't specified to compile for x86 :)

What do you think happens when you compile this program with clang like this & run it?

// clang -O2 -o yikes yikes.c

#include <stdio.h>

int main(void)
{
int *yikes = NULL;
*yikes = 1;

fprintf(stdout, "Hello world!\n");

return 0;
}

This is by far and away the craziest story I have ever reported. The lede probably doesn't do it justice, but I promise this will be a fascinating (if not also entertaining) read. I'd frankly be amazed if some version of this story isn't made into a documentary or drama series:

A California man accused of failing to pay taxes on tens of millions of dollars allegedly earned from cybercrime also paid local police officers hundreds of thousands of dollars to help him extort, intimidate and silence rivals and former business partners, a new indictment charges. KrebsOnSecurity has learned that many of the man’s alleged targets were members of UGNazi, a hacker group behind multiple high-profile breaches and cyberattacks back in 2012.
