There are truisms that span history. One truism is that a single mistake can lead to disaster, and to some extent the series of vulnerabilities affecting the organizations that use Apache Log4j.

Our security research team will explain a real attack scenario from the black box and white box perspective on how a vulnerable AWS Lambda function could be used by attackers as initial access into your cloud environment. Finally, we show the best practices to mitigate this vector of attack. Serverless is becoming mainstream in business applications to achieve scalability, performance, and cost efficiency without managing the underlying infrastructure.

No sooner did word start to spread about Apache Log4j that the usual torrent of blaring headlines, vendor marketing, and tips and tricks-style “information” quickly followed. You can find plenty of solid technical analysis out there about Log4j, and we’ve already posted information about Netskope protections and threat coverage from Netskope Threat Labs. But that’s not this post.

Managing the security of your Amazon Web Services (AWS) environment requires constant vigilance. Your strategy should include identifying potential threats to your environment and proactively monitoring for vulnerabilities and system weaknesses that malicious actors might exploit. In a complex environment—such as your AWS account with a multitude of services, coupled with various architectures and applications—the ideal solution should be both comprehensive and straightforward.

Following the discovery of Log4Shell, a vulnerability in Log4J2, Elastic released a blog post describing how users of our platform can leverage Elastic Security to help defend their networks. We also released an advisory detailing how Elastic products and users are impacted.
