All that glitters is not cryptomining, but almost

There is a new trend in the world of malware, called cryptojacking. In many wars they used enemy prisoners to mine minerals, this would be similar to this case but transferred to the 21st century. It consists in using the

This blog began its journey on March 31, 2014. Four magnificent years that have passed faster than Sonic takes to finish a marathon. Some time ago they published an article in Science that tried to explain why time flies when we

Starting code debugging (II) – Breakpoints

One of the most useful functions provided by debuggers is setting breakpoints in certain lines of code to stop execution at those points and examine the status of the program. Breakpoints can be both hardware and software. GDB can set

Benchmarking Crimes via #arXiv

The evaluation of the prototype that is developed in a scientific work is a very important part of the investigation since it determines if the proposed system fulfills its objectives and how well it does it, which is essential to

A simple click can generate a logic explosion

Not all malware executes its malicious payload instantly as soon as they are downloaded and executed for the first time. Many times, these are kept in the shadow and are triggered only when a certain situation occurs (something like an

Starting code debugging (I)

Errors are a collateral (and undesired) phenomenon that occur when writing code. Some, like syntactic errors, are easy to detect and correct, since normally the compiler,  interpreter or  IDE itself will warn us that we have some open parentheses for

Code-reuse attacks for the Web via #CCS17

Cross-site scripting (XSS) vulnerabilities are a fairly recurrent problem on the web even though it was publicly documented in 2000. These attacks allow a malicious actor to completely alien certain web page to inject and execute code not authorized by

Turning off server room coolers

There it comes that precious moment of the year where the temperature usually has a single number (in Celsius obviously). People tend to think that this is a negative thing, but here we have always been very positive people.

Everything started with the USB of that hacker

When someone finds out that your computer is infected, a question automatically pops up in your mind, how has this happened? First you think about the recent files downloaded / installed, then in the visited pages, and if no answer

Fatal optimizations

Compilers transform the code we write to make it more efficient, however, there are times when these optimizations made by the compiler can cause security problems. A clear example of this is the dead code elimination, an optimization that aims
