Title: JasperLoader targets Europe with Gootkit banking trojan
Description: A loader known as “JasperLoader” has been increasingly active over the past few months and is currently being distributed via malicious spam campaigns primarily targeting central European countries, with a particular focus on Germany and Italy. JasperLoader employs a multi-stage infection process that features several obfuscation techniques that make analysis more difficult. It appears that this loader was designed with resiliency and flexibility in mind, as evidenced in later stages of the infection process.

TOP VULNERABILITY THIS WEEK: Sea Turtle campaign targets well-known DNSs
=========================================================
NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: Sea Turtle campaign highlights dangers of DNS hijacking
Description: Cisco Talos discovered a new cyber threat campaign called “Sea Turtle,” which is targeting public and private entities, including national security organizations, located primarily in the Middle East and North Africa. The ongoing operation likely began as early as January 2017 and has continued through the first quarter of 2019. The investigation revealed that at least 40 different organizations across 13 different countries were compromised during this campaign. Talos assesses with high confidence that this activity is being carried out by an advanced, state-sponsored actor that seeks to obtain persistent access to sensitive networks and systems.
