Suport technique et veille technologique

Aujourd’hui, les grandes entreprises et administrations publiques hésitent entre continuer à utiliser des logiciels propriétaires ou basculer vers les Logiciels Libres. Pourtant, la plupart des logiciels libres sont capables de bien traiter les données issues des logiciels propriétaire, et parfois avec une meilleur compatibilité.

C’est alors la barrière de la prise en main qui fait peur, et pourtant...

Les logiciels libres

L’aspect « Logiciel Libre » permet une évolution rapide et une plus grande participation des utilisateurs. Les aides et tutoriels foisonnent sur Internet ou sont directement inclus dans le logiciel lui-même.

Enfin, les concepteurs sont plus proches des utilisateurs, ce qui rend les logiciels libres plus agréable à utiliser et conviviaux.

Grâce à la disponibilité des logiciels libres, vous trouverez facilement des services de support techniques et la licence n’est plus un frein à l’utilisation de ces logiciels par votre personnel.

Notre support technique concerne essentiellement les logiciels libres, que ce soit sous forme de services ponctuels ou de tutoriels.

Web3 is going just great [English]  -  Thwarted hacker asks security firm to reimburse gas fees

 -  Mars 2023 - 

Two diagonal ovals, followed by "ParaSpace", all in dark grey

File this one under "the audacity".

On March 17, blockchain security company BlockSec observed an attacker trying to exploit a vulnerability in the NFT lending project Paraspace. Although they had successfully identified a vulnerability that could have allowed them to steal 2,900 ETH (a bit over $5 million), their attempt to execute the hack failed because they didn't correctly estimate what it would cost them in gas fees.

After observing the attempt, BlockSec executed a whitehat rescue, where they successfully executed the same attack to remove the funds from Paraspace and secure them until they could return them to the project team.

Incredibly, the exploiter sent an on-chain message to BlockSec: "hey man, I am the one who made the contract you just copied, I couldn't make it work for a stupid gas estimation error. since I lost a lot of money trying to make it work, it would be cool to get at least some of them back... best of luck". Altogether, the would-be attacker spent around 0.7 ETH (~$1,200) on gas fees while trying to pull off the hack.
