The attackers of 2026 do not choose their victims. They scan everything, and they hit whatever is open. A PC or server behind a weak router is not a small target. It is the default target.
Attack tools now run around the clock and reason for themselves. They fingerprint your router, your IoT boxes, your open ports - and they try everything, at machine speed, without ever getting tired. One security firm logged over half a million probes a day against a single ordinary home connection. This traffic is not personal. It is not revenge. It is simply the cost of being online in 2026.
Routers and IoT boxes are the favourite first step: old firmware, no updates, default passwords. A compromised router sees everything - your banking sessions, your email, your passwords - before they even leave the house.
Credentials are the real loot. Stolen logins are sold by the batch, and a single reused password across accounts is enough to start the dominoes. Recent attack waves even abuse AI chatbots to hand-deliver malware: a "helpful" custom GPT that quietly drops a remote-access trojan onto the machine that asked it for help.
And the machines that are not looted directly are often recruited - silent members of a botnet, burning your bandwidth and your electricity inside someone else's attack.
The answer is not willpower. It is a TODO list written by someone who has done it a hundred times, and - in the hardening tier - a pair of hands that already pressed the scary buttons.
A hardened machine looks like this: firewall denies everything incoming by default,
services bind only to loopback, SSH reachable only from your own network or VPN, automatic updates on,
kernel hardening active, and a check + verify report that proves each line.
Nothing is "trust me". Everything is "look". That is the whole pitch.
./sec-toolkit.sh check is read-only and needs no sudo. It inspects firewall state, services, and settings, and changes nothing. Hardening is a separate, explicit, sudo step.
