GTFOBins is a curated list of Unix binaries that can be used to bypass local security restrictions in misconfigured systems.

The project collects legitimate functions of Unix binaries that can be abused to get the f**k break out restricted shells, escalate or maintain elevated privileges, transfer files, spawn bind and reverse shells, and facilitate the other post-exploitation tasks.

It is important to note that this is not a list of exploits, and the programs listed here are not vulnerable per se, rather, GTFOBins is a compendium about how to live off the land when you only have certain binaries available.

GTFOBins is a collaborative project created by Emilio Pinna and Andrea Cardaci where everyone can contribute with additional binaries and techniques.

Comment savoir si ce site marchand fait du dropshipping ?
Par ShevAbam, le 28 Septembre 2021 à 08:30

marketing web ecommerce 

Le dropshipping est une méthode répandue qui consiste à ce qu'un site marchand vende des produits sans en avoir le stock et que son fournisseur livre directement au client. Les prix sont généralement bien plus élevés que si vous trouvez les produits par vous-même sur un autre site. Mais comment savoir si un site marchand pratique le dropshipping ?

C'est une méthode qui présente ses intérêts mais généralement, pour le client, c'est une fausse bonne affaire. En effet, les promotions ou prix barrés affichés sur les sites de dropshipping sont très souvent faux, incitant les consommateurs à passer à l'achat. D'aileurs, les publicités présentes sur les réseaux sociaux sont très souvent liées à du dropshipping.

Mais comment savoir si on achète un article 3 ou 4 fois son prix ? La plupart des marchands faisant du dropshipping s'approvisionnent sur AliExpress ou autre site ecommerce chinois. Les prix sont très bas et il n'est pas rare qu'un site de dropshipping propose les mêmes articles bien plus chers.

C'est là qu'intervient le site AntiDrop. Si vous avez un doute, copiez l'adresse du site suspect et insérez-la sur le site AntiDrop. Après quelques instants, le résultat tombe et vous saurez si vous avez failli payer bien plus cher un article !

Nerd Fonts – Les meilleurs polices pour les développeurs

@Korben — 19 août 2021

Les polices de caractères, c’est cool, mais ce n’est pas forcement adapté à tous nos usages de nerds… Parfois, notre police (ou font) préférée manque de certains symboles et ça fait des carrés chelous dans nos terminaux ou nos IDE.

Heureusement, il existe un super projet collaboratif qui s’appelle Nerd Fonts et qui vise à patcher les polices de caractères les plus appréciées des développeurs et autres informaticiens en y ajouter un grand nombre de glyphs (icones) en provenance de projets que vous connaissez tous :

Powerline Extra Symbols
Font Awesome
Font Awesome Extension
Material Design Icons
Weather Icons
Devicons
Octicons
Font Logos (Formerly Font Linux)
Pomicons
IEC Power Symbols
Seti-UI + Custom

The /bin/true Command and Copyright
by John Chambers

One of the fun examples among all the copyright fuss is the extreme example of copyright claims made by AT&T some time in the 1980s. It's the /bin/true program. This is a "dummy" library program whose main function is to make it easy to write infinite loops (while true do ...) in shells scripts. The "true" program does nothing; it merely exits with a zero exit status. This can be done with an empty file that's marked executable, and that's what it was in the earliest unix system libraries. Such an empty file will be interpreted as a shell script that does nothing, and since it does this successfully, the shell exits with a zero exit status. But AT&T's lawyers decided that this was worthy of copyright protection.

The earliest copyrighted version of /bin/true that I've found so far dates from 1984:

That's the entire file. I've added the initial "| " so that you can see the exact contents. Note that it only contains blank lines and a comment (the #ident line identifying it as the "true" command). That's right; AT&T claimed copyright on three blank lines. So if you use blank lines in any of your files, you are in blatant violation of AT&T's copyright claim.

Lest you think that this is a fluke that was quickly corrected, here is the /bin/true program from AT&T's Sys/V libraries as of 1990:

Note that there is still nothing in this script except three blank lines and a copyright notice, plus the #ident line that now identifies it as version 1.6.

It might also be noted that, since I am "publishing" the entire contents of an AT&T program I am in blatant violation of AT&T's copyright claim. I've pointed this out publicly on numerous occations, in various technical forums, since the early 1980's. So far I haven't heard a word from any AT&T lawyers. Anyone have any idea why they are ignoring such a violation?

We might also note that linux systems avoid violating this copyright by replacing /bin/true with a compiled binary. This also runs a lot faster than the above shell script, since it avoids firing up a second unrelated program (/bin/sh) to do nothing. This is yet another reason that linux outperforms unix. And they were apparently forced into this efficiency improvement by AT&T's copyright claim. ;-)

Addendum:

AT&T isn't the only company to do such things. Here's the same program on a Solaris system in 1993:

Note that there is one less blank line here; it has been replaced by the #! line. But otherwise it is identical. Sun has merely passed on the copyright notice. I wonder if Sun has written permission from AT&T to use blank lines in their code? And I'm a bit disappointed that Sun didn't replace "AT&T" with "Sun Microsystems" throughout. Maybe their lawyers advised not to do this.
Meanwhile, the nice folks at GNU have handled this issue by reimplementing the "true" command in C. This program isn't just smaller and faster than the old shell script, which requires firing up a new shell process to successfully do nothing. They also added some important command-line options:

--help display this help and exit
--version output version information and exit

Presumably these options were added so they could claim that this wasn't just a stolen copy of the AT&T code; the GNU version actually contains code that does something. Those GNU folks do have a sense of humor. Here's the result of the --version option on a handy linux (knoppix) system in 2007. Note that it's up to version 5.94. Note also the claim that there is no warranty, which in this case presumably means that if the program actually does something, you can't sue them. And note that this version does something that's almost unknown in the software business: It includes an attribution giving the programmer's name.

The /bin/true (or /usr/bin/true) command is now nearly obsolete, because most extant shells now have a builtin "true" command. But it's still useful occasionally, for various silly reasons, and the attempts to copyright it are still a good source of absurdist humor. It's especially fun to note that GNU has reason to copyright their version. This prevents AT&T, Sun or SCO from taking the GNU code, claiming it as their own, and suing the linux crowd for infringement. Copyright © John Chambers, 1990, 1993, 2003, 2007, 2009 ;-)
