Celulares baratos e de marcas pouco conhecidas estão chegando a consumidores brasileiros e de outros países com malware embutido no firmware do sistema operacional Android (e portanto impossível de ser removido).

Why it matters

Most incidents that end up being expensive did not start with a sophisticated technique. They started with an account that should have been closed when somebody resigned, a server nobody knew was still on, or a broad permission granted to unblock someone that then stayed forever.

I separate technical risk from business risk, because they do not always match. A critical vulnerability in an isolated system matters less than a medium one in the system that issues invoices. Prioritising by severity without looking at where the money is is an expensive way to work hard and protect little.

What usually goes wrong

Where it usually breaks is response, not prevention. There are tools, there are alerts, and when something real happens nobody knows who decides to disconnect, who gets called first, or what the customer is told. Valuable hours get lost arguing about that while the problem grows.

What to watch

  • How long it took to detect, usually the most revealing metric in the whole case.
  • Whether initial access came from a legitimate account handled badly, which is the most frequent pattern.
  • What could be restored and how fast — a backup that was never tested does not count.

How I read this entry

What I would review this very week is access: accounts belonging to people who left, permissions that grew without anyone trimming them, and shared credentials everybody swears do not exist. It is the least glamorous work and the one that cuts off the most attacks.
