We have enabled a new scan for exposed CoAP (Constrained Application Protocol) devices on port 5683/UDP. The scan has uncovered around 460 000 exposed CoAP services that can be potentially abused for CoAP amplification DDoS attacks. These services may also leak information or expose other vulnerabilities. This is the third IoT scan implemented as part of the EU CEF VARIoT project.

We have enabled a new scan dedicated to finding open IPP (Internet Printing Protocol) devices exposed on port 631/TCP. The roughly 80,000 devices uncovered as a result of the scan have connected to the Internet without adequate access controls or authorization mechanisms in place. This could allow for a potential range of different types of attacks, from information disclosure and service disruption/tampering, to, in some cases, remote command execution. Results of the scan are collected in the new Open IPP report. This is the second scan enabled under the EU CEF VARIoT project.

This blog is the first in a series in which we will take a look at different world regions in order to demonstrate what taking a more holistic view of our data can reveal - starting with the African continent. The derived insight helps us better drive our outreach activities and hopefully allows National CSIRTs in the region, as well as numerous other authorities/partners and private enterprises, to enhance their incident response coordination and share information from our public benefit victim remediation network reports with local communities in a more effective manner.

New MQTT IPv4 scans are now carried out daily as part of our efforts to expand our capability to enable the mapping of exposed IoT devices on the Internet. A new report - Open MQTT - is now shared in our free daily victim remediation reports to 107 National CSIRTs and 4600+ network owners. In particular, the report identifies accessible MQTT broker service that enable anonymous access. The work is being carried out as part of the EU CEF VARIoT (Vulnerability and Attack Repository for IoT) project.

Celebrating a particularly significant long term milestone - our 107th National CERT/CSIRT recently signed up for Shadowserver's free daily networking reporting service, which takes us to 136 countries and over 90% of the IPv4 Internet by IP space/ASN. This has finally changed our internal CERT reporting coverage map of Europe entirely green.

Between May 2016 and April 2019, The Shadowserver Foundation participated in the SISSDEN EU Horizon 2020 project. The main goal of the project was to improve the cybersecurity posture of EU entities and end users through the development of situational awareness and sharing of actionable information. It exceeded KPIs, with 257 sensors in 59 countries, using 974 IP addresses across 119 ASNs and 383 unique /24 (Class C) networks, and collected 31TB of threat data. This blog post provides detail on Shadowserver's role in SISSDEN, including a 3 minute explainer video.

Shadowserver has been participating in an EU Horizon 2020 funded project called SISSDEN from May 2016 to April 2019. Multiple network report types have become available due to the deployment and operation of a new large scale distributed honeypot sensor network, as well as from other SISSDEN partner collected attack data sets. This data is available to subscribers via our free daily network remediation reports.

While this has been communicated via e-mail to most of our report recipients, we wanted to make a quick note on our blog regarding the Open Resolver report that recently went out dated 2014-05-22. Please disregard the DNS openresolver data from this data. It lists all DNS servers, not only the ones that are open resolvers.
