We are happy to announce the first major extension to our newly launched Dashboard - the addition of IoT device statistics and server-side attack statistics, data sets that have been collected as part of the HaDEA EU CEF VARIoT project.

After many years of not having public interface for exploring our extensive cyber threat intelligence data sets, Shadowserver are very excited to make available our new public Dashboard, kindly funded by the UK FCDO. Use our Dashboard to dig into two years of aggregated country level data about many different type of threats, including some unique data sets and vantage points, then visualize the data in various ways that can be easily shared via URLs. Free to use (with attribution) for research, informing policy makers and by journalists/news media in educating the public about cyber security threats.

A maximum risk critical vulnerability in the popular Apache Log4j open source logging software was made public as CVE-2021-44228 on December 9th 2021, potentially providing attackers with easy remote code execution on thousands of systems globally. Although Shadowserver decided not to scan for this vulnerability, our honeypots continue to detect IPv4 /0 scanning and exploitation attempts. A second run of our Vulnerable Log4j Servers Special Report provides updated data from Alpha Strike Lab's scanning activity performed during the week since our first Special Report. The updated Special Report is being distributed to National CSIRTs and network owners as a public benefit service to aid in rapid remediation.

After our recent Special Report and blog post about vulnerable log4j servers, a quick and dirty update on the “log4shell” mass scanning and attempted CVE-2021-44228 exploitation activity we have been seeing across our global honeypot sensor network between Sunday December 11th and Thursday December 16th, including a quick analysis of the top ten Malware Callback URIs observed and server distribution.

A maximum risk critical vulnerability in the popular Apache Log4j open source logging software was made public as CVE-2021-44228 on December 9th 2021, potentially providing attackers with easy remote code execution on thousands of systems globally. Although Shadowserver decided not to scan for this vulnerability, our honeypots detected rapid growth in IPv4 /0 scanning. This Special Report provides data from Alpha Strike Labs's scanning activity and is being distributed to National CSIRTs and network owners as a public benefit service to aid in rapid remediation.

Shadowserver received funding from the UK FCDO in Q1 2021 for a short surge to improve the support we offered to Africa and the Indo-Pacific region. We achieved some good results, so we are providing some public highlights in this blog post. We are also pleased to announce that we have received some additional FCDO funding to continue these efforts through Q4 2021 and Q1 2022, and hope to further expand our free public benefit service coverage to more National CSIRT and additional network owner (ASNs) in these target regions.

Over the years, Shadowserver’s report list has grown considerably from when we originally started. When some of these reports were originally set up, the requirements were different to those needed today. We have therefore decided to implement changes with some of the existing report types, especially those related to our sinkholes and honeypots, as well as remove some legacy reports. Changes will come into effect on 2021-06-01. On that day, the old reports will cease and only the new equivalents will be sent out. Until that time, starting 2021-04-05 both the old reports and new reports will function in parallel.

Can you help Shadowserver sign up more countries/networks in Africa and the Info-Pacific to receive our free daily network reports and help secure the Internet? We are running a UK FCDO funded surge in Feb/March 2021, aimed at increasing outreach and expanding our honeypot sensor network in those regions. We are seeking introductions, contacts and hosting so please get in touch if you can help us achieve these goals.

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.
