Latest cybersecurity news from CISA, Krebs on Security, and other trusted sources
This activity was found and reported by BACS student Adam Thorman as part of one of his assignments which I posted his final paper [1] last week. This activity appeared to only have occurred on the 19 Feb 2026 where at least 2 sensors detected on the same day by DShield sensor in the cowrie logs an echo command that included: "MAGIC_PAYLOAD_KILLER_HERE_OR_LEAVE_EMPTY_iranbot_was_here". My DShield sensor captured activity from source IP 64.89.161.198 between 30 Jan - 22 Feb 2026 that included portscans, a successful login via Telnet (TCP/23) and web access that included all the activity listed below captured by the DShield sensor (cowrie, webhoneypot & iptables logs).
A very popular target of attackers scanning our honeypots is "phpmyadmin". phpMyAdmin is a script first released in the late 90s, before many security concepts had&#;x26;#;xc2;&#;x26;#;xa0;been discovered. It&#;x26;#;39;s rich history of vulnerabilities made it a favorite target. Its alternative, "adminer", began appearing about a decade later (https://www.adminer.org). One of its main "selling" points was simplicity. Adminer is just a single PHP file. It requires no configuration. Copy it to your server, and you are ready to go. "adminer" has a much better security record&#;x26;#;xc2;&#;x26;#;xa0;and claims to prioritize security in its development.
Yesterday, in my diary about the scans for "/proxy/" URLs, I noted how attackers are using IPv4-mapped IPv6 addresses to possibly obfuscate their attack. These addresses are defined in RFC 4038. These addresses are one of the many transition mechanisms used to retain some backward compatibility as IPv6 is deployed. Many modern applications use IPv6-only networking code. IPv4-mapped IPv6 addresses can be used to represent IPv4 addresses in these cases. IPv4-mapped IPv6 addresses are not used on the network, but instead, translated to IPv4 before a packet is sent.
Attempts to find proxy servers are among the most common scans our honeypots detect. Most of the time, the attacker attempts to use a host header or include the hostname in the URL to trigger the proxy server forwarding the request. In some cases, common URL prefixes like "/proxy/" are used. This weekend, I noticed a slightly different pattern in our logs:
Introduction
On Wednesday, a phishing message made its way into our handler inbox that contained a fairly typical low-quality lure, but turned out to be quite interesting in the end nonetheless. That is because the accompanying credential stealing web page was dynamically constructed using React and used a legitimate e-mail service for credential collection.

A new vulnerability (CVE-2026-0866) has been published: Zombie Zip.
Microsoft today released patches for 93 vulnerabilities, including 9 vulnerabilities in Chromium affecting Microsoft Edge. 8 of the vulnerabilities are rated critical. 2 were disclosed prior to today but have not yet been exploited. This update addresses no already-exploited vulnerabilities.
Last week, two related RFCs were published:
