This issue was discovered and disclosed as part of research resulting in Rapid7's dis

Analyzing ELB Log Data

Thanks to some slick work from our engineering team, we have recently released a lightweight python script that will allow you to pull your Elastic Load Balancer logs from S3 into Logentries. In this implementation, we use AWS Lambda and leverage the S3 trigger, so the script only runs when needed. The full documentation is available here: https://logentries.com/doc/s3-ingestion-with-lambda/

12 Days of HaXmas: Metasploit End of Year Wrapup

This is the seventh post in the series, "The 12 Days of HaXmas." It's the last day of the year, which means that it's time to take a moment to reflect on the ongoing development of the Metasploit Framework, that de facto standard in penetration testing, and my favorite open source project around. While the acquisition of Metasploit way back in 2009 was met with some healthy skepticism, I think this year, it's easy to say that Rapid7's involvement with Metasploit has been an enormously positive

512 Days of HaXmas: Metasploit's IoT WebApp Login Support

This is the sixth post in the series, "The Twelve Days of HaXmas." Well, the year is coming to a close, and it's just about time for the annual breakdown of Metasploit commit action. But before we get to that, I wanted to take a moment to highlight the excellent work we landed in 2015 in adding new web application login support to Metasploit. After all, who needs exploits when your password is "public" or "admin" or "password" or any other of the very few well-known default passwords? Maybe i

12 Days of HaXmas: Santa makes a list and checks it twice, do you?

This post is the fifth in the series, "The Twelve Days of HaXmas." This is the time of the year where kids and adults alike think back over the past year, wondering which of Santa's two lists they will be on. The nice list is reserved for those who say "please" and "thank you", brush their teeth, and of course, those who regularly update and practice their incident response plans. Santa gives presents to the children on the nice list and coal to the ones on the naughty. When the list gets chec

12 Days of HaXmas: Charlie Brown Threat Intelligence

This post is the third in the series, "The 12 Days of HaXmas." “Get the biggest aluminum threat feed you can find, Charlie Brown, maybe painted pink.” It has been a few years now since the term “cyber threat intelligence” entered mainstream, and since then it has exploded into a variety of products, all claiming to have the biggest, the best, the shiniest, most aluminum-est threat feed, report, or platform. Much of the advertising and media surrounding threat intelligence capitalizes on fear

How to Log Messages from Slack

We recently added support for unedited HTTP logging in Logentries. This means you can send us log data via HTTPS drain (from heroku), or via any webhook you want. One webhook that we’ve been looking to log for a while is Slack . People are always chatting away on Slack, and this data might be useful some day. You can send the data into Logentries however you want, and then worry about what to do it when you actually need it! First, you’ll need to
