La IA acelera la explotación de vulnerabilidades, ¿están preparadas las empresas?
Para un CIO o un CISO, el reto ya no consiste únicamente en descubrir vulnerabilidades. La verdadera dificultad es decidir cuáles deben corregirse primero cuando el tiempo juega cada vez

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 read it with the same short list as always: second factor on anything that grants access, tested backups kept off the network, and a real inventory of what is exposed to the internet. It is not glamorous, and it still prevents most disasters.
What usually goes wrong
What I see fail most is the backup. It is configured, it runs every night, nobody checks it. The day you need to restore, it turns out it had been failing silently for four months, or that everything was backed up except exactly what was needed. A backup never restored is an assumption.
What to watch
- What could be restored and how fast — a backup that was never tested does not count.
- How it was communicated to customers and regulators, which is where reputational cost is decided.
- Whether third parties or suppliers were in the chain, because the perimeter now includes partners.
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.
