I&#;x26;#;39;m always looking for new ways of manipulating the data captured by my DShield sensor [1]. This time I used Gephi [2] and Graphiz [3] a popular and powerful tool for visualizing and exploring relationships between nodes, to examine the relationship between the source IP, filename and which sensor got a copy of the file. I queried the past 30 days of data stored in my ELK [4] database in Kibana using ES|QL [5][6] to query and export the data and import the result into Gephi.

Threat actors are leveraging complex routing scenarios and misconfigured spoof protections to send phishing emails that appear to be internal communications. These attacks, which have increased since May 2025, use various lures like voicemails, shared documents, and password resets to conduct credential phishing and financial scams. The campaigns, often using PhaaS platforms like Tycoon2FA, are opportunistic and target multiple industries. While Microsoft detects most attempts, organizations can further mitigate risks by properly configuring spoof protections and third-party connectors. The attacks do not affect customers whose Microsoft Exchange MX records point to Office 365, as they are protected by built-in spoofing detections.

Recently, a new "breed" of IP-based KVM devices has been released. In the past, IP-based KVM devices required dedicated "server-grade" hardware using IPMI. They often cost several $100 per server, and are only available for specific systems that support the respective add-on cards. These cards are usually used to provide "Lights Out" access to servers, allowing a complete reboot and interaction with the pre-boot environment via simple web-based tools. In some cases, these IPMI tools can also be used via various enterprise/data center management tools.

CVE-2025-43706 is a high-severity vulnerability affecting multiple Samsung Exynos processors used in mobile devices, wearables, and modems. The flaw arises from incorrect handling of RRC (Radio Resource Control) packets at the L2 layer, which can be exploited remotely without authentication or user interaction to cause a Denial of Service (DoS). This vulnerability impacts the availability of affected devices by potentially crashing or disabling network connectivity. Although no known exploits are currently reported in the wild, the ease of exploitation and broad device usage pose a significant risk. European organizations relying on Samsung-based mobile and IoT devices could face operational disruptions, especially in sectors dependent on continuous connectivity. Mitigation requires close collaboration with device manufacturers for firmware updates and network-level protections. Countries with high Samsung device penetration and advanced mobile infrastructure, such as Germany, France, the UK, Italy, and Spain, are most likely to be affected. Given the vulnerability’s characteristics, the severity is assessed as high, emphasizing the need for proactive defense measures.
