It also briefly evokes robotic pizza preparation. ### Source excerpt Information is not meaningful simply because it exists or because it is improbable. It becomes meaningful only if there exists a system that can interpret it and use it to perform a function. At first glance, asking whether Internet Exchange Points (IXPs) make the Internet faster may seem almost provocative at a peering forum. Surely the answer is simply 'yes'? If you're dealing with industrial protocols, you'll certainly have seen Modbus packets in your network. But what are these packets used for, and what data do they contain? Yet I have become increasingly concerned that, in the case of IPv6, we are evaluating the technology almost entirely from the perspective of what it allows networks to do, while giving insufficient attention to what it may allow network operators, corporations and governments to do to their users and if the benefits outweigh the risks. The future of fast food was supposed to look something like this: walk into a restaurant, place an order, and watch a robot assemble your pizza with machine-like precision. ## MikroTik router flaws allow takeover without a password DevFeed: [MikroTik router flaws allow takeover without a password]() Original publisher: [Read original article]() Author: Pieter Arntz Published: 2026-09-08T09:49:16Z Content type: news Language: en Sources: [Malwarebytes]() Topics: [Cybersecurity](), [Vulnerabilities](), [Networks](), [passwords]() Tags: [authentication](), [cve-2026-67276](), [cve-2026-86060](), [cybersecurity](), [mikrotik](), [news](), [ssh](), [update](), [vulnerabilities]() ### AI overview Attackers are actively exploiting two MikroTik RouterOS flaws, dubbed MikroTrick, to bypass SSH authentication and escalate privileges on internet-exposed routers.

It describes how threat actors use AI-generated exploitation scripts for reconnaissance and capability building, and outlines mitigations including removing direct internet exposure, segmenting OT from IT networks, and hardening access controls. ### Source excerpt A joint cybersecurity advisory released by multiple U.S. government agencies warns that threat actors are using AI-generated exploitation scripts to target exposed Siemens S7 Series PLCs across critical infrastructure sectors. Key Takeaways Unattributed threat actors are exploiting known weaknesses and unnecessary internet exposure to conduct reconnaissance and possible pre-positioning for future disruptive attacks against Siemens S7 Series PLCs. The attackers are leveraging AI to build and refine exploit scripts faster than manual development would allow. AI use lowers the technical bar for ICS attacks in a way defenders haven't had to plan for before. There is no single patch, because there is no single flaw. Mitigation depends on removing Siemens S7 Series PLCs from direct internet exposure, segmenting OT from IT networks and hardening access controls. Background On August 19, 2026, the National Security Agency (NSA), the Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), the Department of Energy (DOE) and the Environmental Protection Agency (EPA) released a joint Cybersecurity Advisory (AA26-231A) warning that threat actors are actively targeting Siemens S7 Series programmable logic controllers (PLCs) that are exposed to the internet or insufficiently segmented from it. The activity spans the S7-200, S7-300, S7-400, S7-1200 and S7-1500 series and most heavily affects the Critical Manufacturing, Energy, Water and Wastewater, Chemical, Food and Agriculture and Commercial Facilities sectors, with potential exposure in the Defense Industrial Base as well.
