Rafael Núñez Aponte · 28 July 2026
Computer Weekly en Español · 28 July 2026
Artificial intelligence compresses the time between discovering a flaw and exploiting it. The challenge is no longer finding patches; it is applying them in time.

Extortion entered automatic mode
Rafael Núñez Aponte · 7 July 2026
Computer Weekly en Español · 7 July 2026
Digital extortion is becoming industrial. Defence will also have to become autonomous, without losing human judgement in the final decision.

The new frontier: agentic cybersecurity
Rafael Núñez Aponte · 31 March 2026
Computer Weekly en Español · 31 March 2026
Agentic cybersecurity changes the board: agents that execute, not merely suggest. Risk governance has to match that speed.
Column in Caraota Digital. Each link opens the original publication.
Caraota Digital · Radar Cibernético · 3 September 2026
A column on how certain threats do not age with technology: they survive a change of platform because they exploit habits, not novelty.
Caraota Digital · Radar Cibernético · 27 August 2026
An analysis of a vector that reuses expired cards through physical access and contactless retransmission. Risk is not always in what is new.
Caraota Digital · Radar Cibernético · 13 August 2026
When the fix arrives after the attacker has already occupied the house, the patch ceases to be strategy and becomes a chronicle.
Caraota Digital · Radar Cibernético · 6 August 2026
An executive reading of Black Hat 2026: AI stops being a support tool and starts rehearsing offensive reasoning.
Caraota Digital · Radar Cibernético · 23 July 2026
Attackers do not only look for systems. They look for moments: blackouts, conflicts and political noise, to enter when attention is elsewhere.
Caraota Digital · Radar Cibernético · 16 July 2026
On GOLD EAGLE and the shift towards sharing vulnerabilities detected by AI. Latin America is still building institutions while others already operate doctrine.
Caraota Digital · Radar Cibernético · 9 July 2026
Buying tools is not the same as governing risk. Cybersecurity is an organisational capability, not a licence.
Caraota Digital · Radar Cibernético · 25 June 2026
Digital identity is not a profile that is switched off. It is an asset that is governed, corrected and defended over time.
Caraota Digital · Radar Cibernético · 11 June 2026
Ransomware is no longer a server problem. It is a problem of the board, of reputation and of business continuity.
Caraota Digital · Radar Cibernético · 4 June 2026
Postponement is a vulnerability. The attacker does not share the company’s internal calendar.
Caraota Digital · Radar Cibernético · 7 April 2026
Reputation protects the organisation’s future. If it is not governed, someone else will write the story of the incident.
Original analysis for boards and senior leadership. These are not columns from an external outlet.
Crisis and continuity
Rafael Núñez Aponte
RNA · 2026 09 03
Valid 09/26
The incident does not begin when the system falls. It begins when someone has to decide with incomplete information. What happens in 120 minutes defines the rest.
3 September 2026
Ransomware
Rafael Núñez Aponte
RNA · 2026 09 03
Valid 09/26
A board that only asks whether the backup exists arrives late. The useful questions are about evidence, payment, communication and the minimum operation that must survive.
3 September 2026
Cyber intelligence
Rafael Núñez Aponte
RNA · 2026 09 03
Valid 09/26
Intelligence is what changes a decision this week. A feed of alerts that nobody uses is noise with a letterhead.
3 September 2026
Crisis and continuity
Rafael Núñez Aponte
RNA · 2026 09 03
Valid 09/26
Restoring a server is not restoring a company. Continuity is measured in clients served, payroll paid and trust intact.
3 September 2026
Digital reputation
Rafael Núñez Aponte
RNA · 2026 09 03
Valid 09/26
The first public sentence must contain facts and no ornaments. Silence is filled by others if the organisation does not speak with evidence.
3 September 2026
Artificial intelligence
Rafael Núñez Aponte
RNA · 2026 09 03
Valid 09/26
Unauthorised tools, agents that execute and models that accelerate the attacker. The risk no longer waits for the innovation committee.
3 September 2026
Leadership
Rafael Núñez Aponte
RNA · 2026 09 03
Valid 09/26
Most successful intrusions do not start at a firewall. They start in a conversation, an email or a hurry.
3 September 2026
Digital identity
Rafael Núñez Aponte
RNA · 2026 09 03
Valid 09/26
If an organisation does not govern its name, someone else will write the summary that journalists, clients and language models will repeat.
3 September 2026
Leadership
Rafael Núñez Aponte
RNA · 2026 09 03
Valid 09/26
Communicating is not filling the silence with adjectives. It is saying what is known, what is not known and who is deciding.
3 September 2026
Corporate governance
Rafael Núñez Aponte
RNA · 2026 09 03
Valid 09/26
There are decisions that cannot be left only to the technical team: who can stop production, what residual risk was approved, and who speaks on the day of the incident.
