This year's AllStars took place in Amsterdam in September, alongside the two-day Global AppSec conference. The event offers a full day of the best hand-picked lectures from top speakers and researchers in the field of information security. G DATA virus analyst Karsten Hahn was there and presented…

The Emotet malware is still considered one of the most dangerous threats to corporate IT worldwide. Analysts at G DATA Advanced Analytics have tracked down how an Emotet infection starts gradually infiltrating corporate networks and then takes them out of operation bit by bit.

With its DeepRay AI technology, G DATA is leading the way against rapidly changing malware. Carl-Benedikt Bender, leader of the development team behind DeepRay, explains how the technology works and what specific challenges arose during development.

Certificates are an established method for verifying the legitimacy of an application. If malicious actors succeed in undermining a certificate authority (CA) by either stealing a valid certificate or compromising the CA, the entire model unravels. We have taken a look at a case where this has…

Malware actors very rarely stick to the same script for extended periods of time. They constantly modify and update their attack methods. Recently we have observed malware that uses server-side polymorphism to hide its payload, which consists of a backdoor fully written in PowerShell.

The third part of the StrangeBits series has the ultimate solution for ransomware, explains why some malware is bloated and looks into a supposedly new skulls and bones malware infection.
