    What’s up Emotet?

    Date of publication: 18/02/2020, Michał Praszmo

    What’s up, Emotet?

    Emotet is one of the most widespread and havoc-wreaking malware families currently out there. Due to its modular structure, it’s able to easily evolve over time and gain new features without having to modify the core.

    Its first version dates back to 2014. Back then it was primarily a banking trojan. These days Emotet is known mostly for its spamming capabilities and as a delivery mechanism of other malware strains.

    SECURE 2019 – Call for Speakers

    Date of publication: 25/04/2019, misza

    Call for Speakers for SECURE 2019 is now open. If you have an interesting topic and would like to share your ideas with a crowd of Polish and international IT security specialists, please consider submitting your proposal. You will find all applicable information below.

    SECURE 2019 will be held on October 22-23, 2019 in Warsaw, Poland. This annual conference is dedicated entirely to IT security and addressed to administrators, security team members and practitioners in this field. SECURE’s unique feature is the organisers’ commitment to providing participants with reliable information about everything that is current and meaningful in IT security. A high professional level of the talks is ensured by CERT Polska during the paper selection process. Particular emphasis is on practical solutions, analysis of the current threats, latest trends in countering threats as well as important legal issues. Participants have an opportunity to gain the latest knowledge, improve their qualifications and exchange experience with experts.

    Impersonating online payment service providers was the most popular attack scenario used for targeting e-banking users over the last year. The evolution of malware (increasingly affecting mobile devices and Internet of Things) still remains a challenge for IT security professionals. Another observed trend is usage of previously unknown 0-day vulnerabilities by APT groups. The VPNFilter case shows that advanced attacks can also affect an ordinary user. The question arises, how to take care of privacy and security in the face of above? We will try to find the answer to these and many more questions during SECURE 2019.

    If you want to share your experience in these topics, or if you are an expert in one of the areas below, this Call for Speakers is for you.

    Detricking TrickBot Loader

    Date of publication: 05/02/2019, Michał Praszmo


      TrickBot (TrickLoader) is a modular financial malware that first surfaced in October in 20161. Almost immediately researchers have noticed similarities with a credential-stealer called Dyre. It is still believed that those two families might’ve been developed by the same actor.

      But in this article we will not focus on the core itself but rather the loader whose job is to decrypt the payload and execute it.
