Six vectors that explain 2026

AI adoption grew the attack surface before it grew the defence. The 2026 reports tell the same story from different angles: the attacker gets in through the flaw, automates with AI and charges in data.

Vulnerability exploitation

Old versions, unpatched libraries and forgotten endpoints are found by automated scanning. For the first time the software flaw beats the stolen password as the way in.

31%of breachesVerizon DBIR 2026 · May 2026

Ransomware

Encrypt and extort remains the dominant business model. Tested backups and segmentation decide whether the incident is a scare or weeks of downtime.

48%of breaches involve ransomwareVerizon DBIR 2026 · May 2026

Phishing and social engineering

E-mail, voice and SMS, now with AI-generated text and voice. In Brazil it is the costliest vector measured by IBM: BRL 7.93 million per breach.

Supply chain

A compromised vendor, library or integration becomes your breach. In Brazil, 16% of incidents and BRL 7.32 million on average.

48%of breaches involve a third partyVerizon DBIR 2026 · May 2026

Shadow IT and shadow AI

Employees paste customer data into tools the company does not govern. Frequent AI use tripled in a year; unauthorised apps make the breach more expensive.

The model reads what the attacker wrote

Every application that hands external content to a language model (e-mails, documents, pages, customer messages) opened a new channel. The risks already have a name, a number and public cases.

OWASP Top 10 for LLM Applications 2026

Published in August 2026 and mapped to the OWASP Top 10 for Agentic Applications. The top three:

  1. 01
    Prompt injection

    Hidden instructions in the content the model reads redirect what it does. Number one since the first edition.

  2. 02
    Sensitive information disclosure

    Personal data, secrets and system instructions leaving in the answers, including to people who should not see them.

  3. 03
    Excessive agency

    Agents with more tools, permissions and autonomy than needed. Up from sixth place in 2025 to third.

Public cases, with date and official advisory

  1. EchoLeak: zero-click exfiltration in Microsoft 365 Copilot

    CVE-2025-32711

    An e-mail with hidden instructions was enough for the assistant to fetch internal data and send it out. Critical severity (CVSS 9.3), fixed by Microsoft server-side.

  2. Three CVEs in the official Git MCP server

    CVE-2025-68143 · 68144 · 68145

    Argument injection in git_diff and git_checkout and missing path validation allowed writes outside the repository from an agent. CVE-2025-68145 received CVSS 9.1 at the NVD.

    Official advisory / source →

  3. Indirect injection observed on real pages

    Unit 42 documented 22 techniques and 12 cases of instructions planted on web pages to manipulate AI agents that read them: "no longer merely theoretical but is being actively weaponized".

    Official advisory / source →

  4. Generative AI already bolsters 15% of attack techniques

    The Verizon report measured attackers using generative AI and the jump in employee AI use (15% to 45%), the "shadow AI" that leaks data without anyone attacking.

    Official advisory / source →

  5. AI-driven attacks up 56%

    According to IBM, deepfakes and AI-enabled malware lead the global rise; globally, a breach caused by an AI-generated attack costs on average BRL 35 million, about BRL 6 million above other incidents.

    The assessment stays with your company, including to hire another vendor. Clear price in a written proposal.

  • In technology since 2006

    Systems supported for years, a per-client version inventory and the 2026 PHP2Shell response by order of exposure.

What changed: the way in is now the flaw in the software

In May 2026 Verizon published the 19th edition of its Data Breach Investigations Report with a first: 31% of breaches started with the exploitation of a software vulnerability, overtaking stolen credentials as the main point of entry for the first time. In the same report, 15% of attack techniques already appear bolstered by generative AI, and frequent use of AI tools by employees rose from 15% to 45% in one year.

The practical consequence for a company in Brazil is direct: a system on an old version, a library without updates or a forgotten endpoint is found by automated scanning, not by an attacker who picked the company. The response to PHP2Shell in October 2026 showed it on systems JBKR supports: the per-client version inventory is what made it possible to fix by order of exposure.

Brazil: more attacks, costlier breaches, more ANPD notifications

Latin America was the most attacked region in the world in every month of 2026 measured by Check Point Research: in September, 3,813 attacks per organisation per week against a global average of 2,803, itself up 48% in a year. For Brazil, the same research, released to the press, recorded 4,151 weekly attacks per organisation in July, 45% above the previous year.

Cost follows: according to the IBM report of October 2026, a data breach costs on average BRL 7.44 million in Brazil, a record for the series, with healthcare at BRL 12.55 million. Unauthorised applications used by employees (shadow IT) added BRL 720.3 thousand to the average cost, and only 33% of Brazilian companies plan to increase investment in AI security and governance. On the regulatory side, the ANPD received 423 incident notifications in the first nine months of 2026, 31.8% more than in the same period of 2025, and Resolution CD/ANPD 15/2024 gives three working days to report a relevant incident.

AI: the vector most companies still do not test

When an application reads e-mails, documents, pages or messages and passes that content to a language model, anyone who can place text in that flow can try to instruct the model. That is prompt injection, number one in the OWASP Top 10 for LLM Applications since the first edition and kept there in the 2026 edition, which also raised "excessive agency" (agents with too many permissions and tools) to third place.

It is not theory: in June 2025 Microsoft fixed server-side CVE-2025-32711, a critical flaw (CVSS 9.3) in Microsoft 365 Copilot where an e-mail with hidden instructions was enough to extract data without a user click; between December 2025 and January 2026, three CVEs in the official Git MCP server allowed argument injection and writes outside the repository; and in March 2026 Unit 42 documented 22 indirect injection techniques used on real web pages against AI agents. JBKR has dealt with this long enough to have built a product for the problem: AironCore.

How JBKR works: assess, prioritise, fix, follow up

Everything starts with a fixed-scope assessment: inventory of what is exposed, vulnerability scan, review of the architecture and the critical parts of the code, manual testing of what scanners miss and, where AI is involved, tests for prompt injection, system-prompt leakage and personal data leakage. The output is a report ranked by risk, with the remediation plan and estimates, which stays with your company.

Then we fix with your team or on its behalf, by order of exposure, and leave the follow-up running: version inventory, security updates within the support plan, backups with tested restores and, for AI applications, AironCore in production with Sentinel scanning the application on a schedule and alerting the team on Slack, Teams or e-mail.

What JBKR does not do alone

Corporate network security, a 24/7 SOC, formal forensics and cyber insurance are not JBKR services: we refer and coordinate partners when the assessment shows the need. What we deliver with our own hands is the application and data layer, which is where, by the 2026 numbers, most attacks get in.

Articles by the founder on the subject

  • PHP2Shell: what the critical PHP flaw teaches anyone running an old system

    On 21 October 2026 the PHP project published fixes for two flaws that allow unauthenticated remote code execution, nicknamed PHP2Shell. Brazilian public services went offline the same day. The news that matters for most companies, though, sits in a smaller line of the announcement: anyone running PHP 8.1 or older received no official fix. This article explains what happened, what to do today, and what the flaw says about postponing upgrades.

  • The US$6.3 billion Binance theft is not about crypto: it is about access

    On 29 October 2026 Binance, the world's largest cryptocurrency exchange, suffered the largest theft in the sector's history: about US$6.3 billion in client assets. The company's initial explanation did not mention broken cryptography or a blockchain failure. It mentioned a laptop. This article separates what is known from what is not yet known and translates the episode into five access controls that fit a small company's budget.

  • Backups, ransomware and the real cost of an incident in a small company

    Ransomware is now present in almost half of the data breaches recorded worldwide, and most victims do not pay the ransom: they recover from backup, or they do not recover. This article explains how an attack gets into a 30-person company, what separates a backup that saves you from one the attacker also encrypted, what the LGPD requires within three working days, and how to calculate the cost of an incident before it happens.

  • AI automation: where it pays off in 2026 (and where it still does not)

    The subject moved on from chatbots to processes: models that read, classify, fill in and execute. In practice, AI automation only returns money on processes with volume, a clear rule and a reversible error. This article covers the four places where it pays off in Brazil today, the four where it does not yet, and the cost-of-error maths almost nobody does before signing.

// frequently asked questions

What people ask before hiring

My company is small. Is this really for me?

Yes. The attacks measured by Check Point Research are automated and do not pick a company size: they sweep the internet for vulnerable versions and exposed credentials. A small company usually has fewer layers of defence and fewer people to respond, which is exactly where a fixed-scope assessment with fixes ordered by exposure pays the most per hour.

What is the security assessment and what do I get at the end?

A piece of work with a written scope: an inventory of what is exposed (systems, versions, access, integrations and AI usage), a vulnerability scan plus a review of the architecture and the critical parts of the code, manual testing of what scanners miss, and a report ranked by risk with the remediation plan. The report belongs to your company, including to hire another vendor.

Do you do penetration testing?

Yes: intrusion tests on web applications, APIs, mobile apps and AI applications (including prompt injection and system-prompt leakage), always with written authorisation, an agreed window and rules of engagement. Large networks and infrastructure are covered with partner specialists coordinated by JBKR. The 2026 IBM report lists offensive security testing among the measures that most reduce breach cost in Brazil.

How do you protect an application that uses AI or an LLM?

With what JBKR built for itself: AironCore analyses every prompt before it reaches the model (injection, jailbreak, exfiltration attempts) and every answer before it reaches the user (personal data masked, content outside policy), and its Sentinel module attacks your own application in a controlled way to find what gets through. On top of that: a review of the agent design (permissions, tools, memory), credential isolation and an audit trail per request.

Do you handle an incident in progress?

Yes, within our capacity: containment, evidence preservation, restoration from backup and the communication to the ANPD and to data subjects within the three working days of Resolution CD/ANPD 15/2024. For formal forensics and cyber insurance we refer partners. The best moment to call us is before: the response plan is part of the assessment.

Does this replace antivirus, a network firewall or a SOC?

No. JBKR works at the application and data layer: code, APIs, access, integrations and AI usage. Antivirus, network firewalls and 24/7 monitoring (SOC) remain necessary and can be contracted from partners; we help choose and integrate them.

How much does it cost and how is it contracted?

The assessment is a fixed-scope project, with scope, deadline and price in a written proposal after a free 30-minute call. One-off fixes and tests use the On-Demand plan (from BRL 250 per hour, estimate before the work); continuous follow-up uses the monthly plans. The published prices apply to every JBKR service line.
