Intermittent Censys API Failures

Good morning, We have been seeing intermittent failures with the Censys Search API all weekend, with a further stream of 500 failures this morning. A number of searches via the GUI are also returning 0 results.  We have checked the Censys status board, which does not suggest that there are availability issues with the API. Please can you investigate.

New: Censys Internet of Healthcare Things (IoHT) Research

Hi folks, We just published a report examining the most commonly exposed types of assets belonging to the Internet of Healthcare Things (IoHT) 🏥 in Censys data.Ransomware and data breaches in healthcare continue to rise, and effective exposure management in this sector is more critical than ever. Healthcare organizations often have sprawling, decentralized infrastructure and under-resourced IT departments, which create significant challenges.We examined the global external attack surface of publicly accessible medical devices and IoHT applications and found legacy protocols, unauthenticated medical image databases, and data platforms with histories of exploited vulnerabilities.You can read the full report here: https://censys.com/state-of-internet-of-healthcare-things/

Manufacturing Use Case Queries for Search & ASM

Hi there! Censys recently published a blog about the prevalence of ransomware attacks on manufacturing firms, based on new research from GRF. Within the blog, our team included some manufacturing use case queries you can run in Censys Search and Censys ASM to identify and monitor relevant protocols, like those for building automation, PLC communication, HMI/SCADA, and more. Examples: Building Automation ProtocolsBACnetSearch Query: services.service_name:BACNET ASM Query: host.services.service_name:BACNETHMI/SCADARed Lion CrimsonSearch Query: services.service_name:REDLION_CRIMSON or services.software:(vendor=”Red Lion” and product=”Crimson”) ASM Query: host.services.service_name:REDLION_CRIMSON or host.services.software:(vendor=”Red Lion” and product=”Crimson”) You can check out the full article here: https://censys.com/top-targets-the-impact-of-ransomware-on-manufacturing/

Tracking the TellYouThePass Ransomware Campaign

The recently disclosed CVE-2024-4577 PHP vulnerability has been rapidly weaponized by the TellYouThePass ransomware gang to breach servers and encrypt files since around June 7, 2024. Censys published a live dashboard tracking publicly exposed infected hosts, observing around 1,000 as of June 13, primarily geolocated in China. The Censys Research Team first wrote about this issue in an advisory published on June 10, 2024: https://censys.com/cve-2024-4577/. This latest blog expands upon the evolving exploitation of the vulnerability, the TellYouThePass campaign, and the team’s observations regarding compromised hosts.
