MISC 107 -

Hello,

Cela faisait longtemps que je n'avais pas contribué à MISC, non pas par manque de temps ou de motivation mais tout simplement par manque de sujet intéressant. Il devient difficile pour moi de trouver des sujets qui n'ont pas déjà été exposés dans MISC, et je dois bien avouer que je ne prends pas forcément le temps non plus de me creuser le caillou pour trouver des sujets.

Celui-ci est plutôt lié à mon actualité professionnelle, puisque depuis de nombreux mois je vois de plus en plus de malwares (notamment en APT) utilisant des plateformes légitimes pour gérer leurs communications.

Je vous invite donc à lire mon nouvel article dans MISC 107 sur ce sujet.

Et bonnes fêtes de fin d'année ! :-)

Interview dans Libération - RETADUP

Hello,

J'ai récemment été interviewé par Libération à propos de RETADUP.

Le buzz du moment sur Retadup m'a laissé un peu aigri, parce que de nombreux articles écrits par des journalistes non méticuleux indiquent que c'est la société Avast qui a découvert Retadup en Mars 2019, alors que j'ai bloggé en compagnie de mes collègues sur le sujet à plusieurs reprises en 2017:

http://blog.trendmicro.com/trendlabs-security-intelligence/new-retadup-variants-hit-south-america-turn-cryptocurrency-mining/

Ceci n'enlève rien bien sûr à l'excellent travail fourni par le C3N de la Gendarmerie Nationale, et la société Avast. Bravo à eux ! :-)

Fake Judicial Spam Leads to Backdoor with Fake Certificate Authority

Here is the link to a new blog post I wrote with friends Kenney Lu and Dark Luo from Trend Micro.

It has several interesting aspects, in my mind:

  • The fact that there is an ongoing campaign against french people, using french material, which is rare enough to be worth mentioning;
  • The fact that there is a kit used to drop different payloads: Gootkit, CryptoWall, some banking trojan...;
  • The fact that it uses an innovating method to infect the victims computers.

Hope you will enjoy the read ! :-)
