Threat actors have started scanning the internet for Windows systems that are vulnerable to the BlueKeep (CVE-2019-0708) vulnerability.
This vulnerability impacts the Remote Desktop Protocol (RDP) service included in older versions of the Windows OS, such as XP, 7, Server 2003, and Server 2008.
Microsoft released fixes for this vulnerability on May 14, as part of the May 2019 Patch Tuesday updates train, and warned users and companies to patch vulnerable systems as soon as possible, classifying the issue as very dangerous, and warning that CVE-2019-0708 could be weaponized to create wormable (self-replicating) exploits.
Many have likened BlueKeep to the EternalBlue exploit that’s been used in 2017 during the WannaCry, NotPetya, and Bad Rabbit ransomware outbreaks.
No proof-of-concept demo code (yet)
For this reason, and because of Microsoft’s doom-and-gloom warning, for the past two weeks, the infosec community has been keeping an eye out for signs of attacks or the publication of any proof-of-concept demo code that could simplify the creation of RDP exploits — and inherently start subsequent attacks.
Until now, no one researcher or security firm has published any such demo exploit code — for obvious reasons, since it could help threat actors start massive attacks.
Nonetheless, several entities have confirmed that they’ve successfully developed exploits for BlueKeep, which they intend to keep private. The list includes Zerodium, McAfee, Kaspersky, Check Point, MalwareTech, and Valthek.
The NCC Group developed detection rules for network security equipment so that companies could detect any exploitation attempts, and 0patch developed a micropatch that can temporarily protect systems until they receive the official update.
Further, RiskSense security researcher Sean Dillon also created a tool that companies can use and test to see if their PC fleets have been correctly patched against the BlueKeep flaw.
BlueKeep scans started over the weekend
But while the infosec community was holding its collective breath thinking attacks may never start, things changed over the weekend.
On Saturday, threat intelligence firm GreyNoise started detecting scans for Windows systems vulnerable to BlueKeep.
Speaking to ZDNet, GreyNoise founder Andrew Morris said they believe the attacker was using the Metasploit module detected by RiskSense to scan the internet for BlueKeep vulnerable host.
“This activity has been observed from exclusively Tor exit nodes and is likely being executed by a single actor,” he said in a tweet on Saturday.
For now, these are only scans, and not actual exploitation attempts.
However, it appears that at least one threat actor is investing quite the time and effort into compiling a list of vulnerable devices, most likely in preparation for the actual attacks.
With at least six entities revealing they’ve come up with private BlueKeep exploits, and with at least two very detailed write-ups on the BlueKeep vulnerability details available online [1, 2], it is only a matter of time until the real bad guys come up with their own exploits as well.
The Tor-originating scans that GreyNoise is currently seeing — and which Morris told ZDNet that are still ongoing at the time of writing — are a first sign that things are about to get worse. Really worse!

Phish Fight: Securing Enterprise Communications
Yes, much of the world may have moved on from email to social media and culturally dubious TikTok dances, yet traditional electronic mail remains a foundation of business communication. And sadly, it remains a prime vector for malware, data leakage, and phishing attacks that can undermine enterprise protections. It doesn’t have to be that way.
In a just released report titled “GigaOm Radar for Phishing Prevention and Detection,” GigaOm Analyst Simon Gibson surveyed more than a dozen enterprise-focused email security solutions. He found a range of approaches to securing communications that often can be fitted together to provide critical, defense-in-depth protection against even determined attackers.

“When evaluating these vendors and their solutions, it is important to consider your own business and workflow,” Gibson writes in the report, stressing the need to deploy solutions that best address your organization’s business workflow and email traffic. “For some it may be preferable to settle on one comprehensive solution, while for others building a best-of-breed architecture from multiple vendors may be preferable.”
In a field of competent solutions, Gibson found that Forcepoint, purchased recently by Raytheon, stood apart thanks to the layered protections provided by its Advanced Classification Engine. Area 1 and Zimperium, meanwhile, are both leaders that exhibit significant momentum, with Area 1 boosted by its recent solution partnership with Virtru, and Zimperium excelling in its deep commitment to mobile message security.
A mobile focus is timely, Gibson says in a video interview for GigaOm. He says companies are “tuning the spigot on” and enabling unprecedented access and reliance on mobile devices, which is creating an urgent need to get ahead of threats.
Gibson’s conclusion in the report? He singles out three things: Defense in depth, awareness of existing patterns and infrastructure, and a healthy respect for the “human factor” that can make security so hard to lock down.
When Is a DevSecOps Vendor Not a DevSecOps Vendor?
DevOps’ general aim is to enable a more efficient process for producing software and technology solutions and bringing stakeholders together to speed up delivery. But we know from experience that this inherently creative, outcome-driven approach often forgets about one thing until too late in the process—security. Too often, security is brought into the timeline just before deployment, risking last minute headaches and major delays. The security team is pushed into being the Greek chorus of the process, “ruining everyone’s fun” by demanding changes and slowing things down.
But as we know, in the complex, multi-cloud and containerized environment we find ourselves in, security is becoming more important and challenging than ever. And the costs of security failure are not only measured in slower deployment, but in compliance breaches and reputational damage.
The term “DevSecOps” has been coined to characterize how security needs to be at the heart of the DevOps process. This is in part principle and part tools. As a principle, DevSecOps fits with the concept of “shifting left,” that is, ensuring that security is treated as early as possible in the development process. So far, so simple.
From a tooling perspective, however, things get more complicated, not least because the market has seen a number of platforms marketing themselves as DevSecOps. As we have been writing our Key Criteria report on the subject, we have learned that not all DevSecOps vendors are necessarily DevSecOps vendors. Specifically, we have learned to distinguish capabilities that directly enable the goals of DevSecOps from a process perspective, from those designed to support DevSecOps practices. We could define them as: “Those that do, and those that help.”
This is how to tell the two types of vendor apart and how to use them.
Vendors Enabling DevSecOps: “Tools That Do”
A number of tools work to facilitate the DevSecOps process -– let’s bite the bullet and call them DevSecOps tools. They help teams set out each stage of software development, bringing siloed teams together behind a unified vision that allows fast, high-quality development, with security considerations at its core. DevSecOps tools work across the development process, for example:
- Create: Help to set and implement policy
- Develop: Apply guidance to the process and aid its implementation
- Test: Facilitate and guide security testing procedures
- Deploy: Provide reports to assure confidence to deploy the application
The key element that sets these tool sets apart is the ability to automate and reduce friction within the development process. They will prompt action, stop a team from moving from one stage to another if the process has not adequately addressed security concerns, and guide the roadmap for the development from start to finish.
Supporting DevSecOps: “Tools That Help”
In this category we place those tools which aid the execution, and monitoring, of good DevSecOps principles. Security scanning and application/infrastructure hardening tools are a key element of these processes: Software composition analysis (SCA) forms a part of the development stage, static/dynamic application security testing (SAST/DAST) is integral to the test stage and runtime app protection (RASP) is a key to the Deploy stage.
Tools like this are a vital part of the security layer of security tooling, especially just before deployment – and they often come with APIs so they can be plugged into the CI/CD process. However, while these capabilities are very important to DevSecOps, they can be seen in more of a supporting role, rather than being DevSecOps tools per se.
DevSecOps-washing is not a good idea for the enterprise
While one might argue that security should never have been shifted right, DevSecOps exists to ensure that security best practices take place across the development lifecycle. A corollary exists to the idea of “tools that help,” namely that organizations implementing these tools are not “doing DevSecOps,” any more than vendors providing these tools are DevSecOps vendors.
The only way to “do” DevSecOps is to fully embrace security at a process management and governance level: This means assessing risk, defining policy, setting review gates, and disallowing progress for insecure deliverables. Organizations that embrace DevSecOps can get help from what we are calling DevSecOps tools, as well as from scanning and hardening tools that help support its goals.
At the end of the day, all security and governance boils down to risk: If you buy a scanning tool so you can check a box that says “DevSecOps,” you are potentially adding to your risk posture, rather than mitigating it. So, get your DevSecOps strategy fixed first, then consider how you can add automation, visibility, and control using “tools that do,” as well as benefit from “tools that help.”
High Performance Application Security Testing
This free 1-hour webinar from GigaOm Research. It is hosted by an expert in Application and API testing, and GigaOm analyst, Jake Dolezal. His presentation will focus on the results of high performance testing we completed against two security mechanisms: ModSecurity on NGINX and NGINX App Protect. Additionally, we tested the AWS Web Application Firewall (WAF) as a fully managed security offering.
While performance is important, it is only one criterion for a Web Application Firewall selection. The results of the report are revealing about these platforms. The methodology will be shown with clarity and transparency on how you might replicate these tests to mimic your own workloads and requirements.
