Rafael Núñez Aponte · 28 July 2026
Computer Weekly en Español · 28 July 2026

The new frontier: agentic cybersecurity

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 · 1 October 2026
A column on zero-click attacks: opening a link is no longer required for someone to get into a phone.
Caraota Digital · Radar Cibernético · 24 September 2026
On a campaign Volexity attributes to a China-linked group that targeted Asian government entities through the browser.
Caraota Digital · Radar Cibernético · 17 September 2026
An FBI announcement of an arrest in Venezuela opens a look at ATM jackpotting: behind the slot is a computer with access to the cash.
Caraota Digital · Radar Cibernético · 10 September 2026
A digital incident far from the hospital can force an emergency room back onto paper. The medicine remains; what breaks is coordination.
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.
Leadership
Rafael Núñez Aponte
RNA · 2026 10 07
Valid 10/26
On 1 October the month’s poster asks people to think before they click. September had already shown another door: a browser sitting behind a fix that was already public.
7 October 2026
Crisis and continuity
Rafael Núñez Aponte
RNA · 2026 10 06
Valid 10/26
On 8 September Microsoft published the largest Patch Tuesday on record. The board that argues about the number has already lost the hour.

Corporate governance
Rafael Núñez Aponte
RNA · 2026 10 05
Valid 10/26
On 27 September Citrix confirmed two NetScaler flaws that asked for neither a user nor a password. Several administrators switched the box off before Monday.

RNA · 2026 10 04
Valid 10/26
From 28 August, Proofpoint saw the same kit in the hands of at least four groups. The question is not who wrote it.

2 October 2026
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.

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.

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.

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.

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.

Communicating is not filling the silence with adjectives. It is saying what is known, what is not known and who is deciding.

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.
