Misconfigured and Exposed: Container Services

The blog highlights the results from Unit 42’s research into misconfigured containers, methods for identifying services exposed to the public, and mitigation steps to secure container services. In this blog, we identify common misconfigurations in container services. This allows our readers to deploy their container platform structures in a more secure and private fashion, avoiding the methods of data gathering that we outline in this blog.

BabyShark Malware Part Two – Attacks Continue Using KimJongRAT and PCRat

In February 2019, Unit 42 published a blog about the BabyShark malware family and the associated spear phishing campaigns targeting U.S. national think tanks. Since that publication, malicious attacks leveraging BabyShark have continued through March and April 2019. The attackers expanded targeting to the cryptocurrency industry, showing that those behind these attacks also have interests in financial gain.

Hunting the Public Cloud for Exposed Hosts and Misconfigurations

This research explores the security landscape of the Internet-facing services hosted in Amazon AWS, Microsoft Azure and Google Cloud Platform. Public cloud is becoming increasingly popular and the reported total spending on cloud infrastructure grew 45.6% in 2018. Amazon AWS maintained its lead with a 31.3% share of the Cloud Service Provider (CSP) market, followed by Microsoft Azure with 16.5%, and Google Cloud Platform, with 9.5%. CSPs offer various “as-a-service” models that give businesses agility and flexibility to scale operations without worrying about the IT infrastructure. However, a single insecure configuration can put the entire infrastructure at risk.
