A Security Shift Driven by Credential Abuse
Cybersecurity is increasingly moving away from the idea that stronger passwords alone can protect critical infrastructure. Snowflake’s decision to eliminate password-based authentication for service accounts is a clear example of that shift. The company is rolling out stronger authentication requirements after years of increasingly sophisticated credential-abuse attacks demonstrated how dangerous long-lived secrets can become when they fall into the wrong hands.
At almost the same time, new research from Palo Alto Networks’ Unit 42 highlights another side of the modern threat landscape: artificial intelligence is making malware development easier and faster, but that does not automatically mean every AI-generated malware sample becomes a successful real-world attack.
Together, these developments point toward a broader cybersecurity lesson. Attackers may be gaining new tools through AI, automation and stolen credentials, but defenders are also changing the architecture of authentication, identity management and detection to reduce the opportunities available to them.
Snowflake Is Phasing Out Passwords for Service Accounts
Snowflake is moving toward a model in which non-human service accounts can no longer authenticate with passwords. According to Snowflake’s documentation, the company is rolling out mandatory stronger authentication for human users while requiring service users to migrate away from password-based authentication. The final enforcement phase is scheduled to roll out between August and October 2026.
This is important because service accounts behave very differently from normal employee accounts. They are designed for applications, automation systems, pipelines and other processes that need to access Snowflake without a person sitting in front of a login screen.
Traditional passwords are poorly suited to that environment. They can be copied into scripts, stored in configuration files, embedded into automation systems or remain active long after the employee or administrator who created them has forgotten about them.
The Real Problem Is Often the Credential, Not the Software
The security distinction is crucial. A compromised account does not necessarily mean that the underlying cloud platform contained a software vulnerability.
In identity-driven attacks, criminals can sometimes obtain legitimate credentials through phishing, infostealers, credential reuse, exposed secrets or compromised third-party systems. Once those credentials are valid, the attacker may appear to the target environment as an authorized user.
That creates a fundamentally different security problem.
Instead of exploiting a software bug, an attacker can simply use an identity that already has permission to access the data.
Snowflake has previously emphasized the risks associated with credential abuse, and the company has described password-only authentication as increasingly inadequate for enterprise environments.
The Hardest Part May Be Finding the Old Accounts
Removing passwords from service accounts sounds straightforward until an organization actually tries to do it.
Large enterprises can have thousands of automated identities operating across data pipelines, applications, analytics platforms, development environments and integrations. Some accounts may have been created years ago and never properly documented.
The biggest question may therefore not be how to change the authentication method.
It may be: Who owns this account, what does it access, and what will break if we change it?
That is where identity inventories become critical.
Ownership Is Becoming a Security Control
An account without a clearly identified owner is a security liability.
If nobody knows why an account exists, nobody can confidently determine whether its privileges are still necessary. An abandoned service account can retain access to valuable data while escaping normal security reviews.
Snowflake’s move therefore highlights a broader enterprise requirement: every non-human identity should have an accountable owner, a defined purpose and clearly documented privileges.
This is not simply administrative housekeeping.
It is part of modern attack-surface management.
Passwordless Authentication Changes the Risk Model
Snowflake supports stronger authentication approaches for service identities, including workload identity federation. The technology allows workloads to authenticate without maintaining long-lived credentials in the traditional sense.
The advantage is straightforward.
Instead of asking an application to protect a permanent password, an organization can establish a trusted relationship between the workload and an identity provider. Authentication can then rely on short-lived or federated credentials rather than static secrets.
That makes credential theft substantially harder to exploit at scale.
Snowflake Is Also Preparing for AI Agents
The timing is particularly interesting because Snowflake has introduced a dedicated SERVICE_AGENT user type for automated AI agents interacting with Snowflake using their own identities and privileges.
The service-agent model includes support for workload identity federation and is designed around non-interactive authentication.
This is significant because the next generation of enterprise software will not consist exclusively of human employees and conventional applications.
AI agents are increasingly becoming another category of digital identity.
If an AI agent can query databases, execute workflows or interact with enterprise applications, organizations will need to know exactly what that agent is allowed to access.
AI Malware Is Growing, but the Numbers Need Context
That brings us to the second major cybersecurity development highlighted in the original report.
Unit 42 analyzed 405 malware samples associated with AI in some way and found that only 12 appeared in telemetry from Cortex XDR-protected production endpoints. Approximately 97% of the samples in the research dataset were not observed reaching real customer environments.
That finding is important because headlines about “AI malware” can easily create the impression that hundreds of autonomous AI-powered attacks are actively spreading across corporate networks.
The evidence is more nuanced.
AI is clearly being used in malware development, but the transition from creating malware to successfully deploying it against defended organizations remains difficult.
AI Is Making Malware Development Faster
The strongest takeaway from the Unit 42 research is not that AI malware is harmless.
It is that AI may be changing the economics of malware development.
Threat actors can use large language models to generate code, modify existing malware, troubleshoot errors and accelerate development. That can reduce the technical barrier for people who previously lacked the expertise required to build functional malicious software.
The result may be more malware experiments, more variants and faster iteration.
But more code does not necessarily mean more successful compromises.
The 97 Percent Number Needs Careful Interpretation
The approximately 97% figure is striking, but it should not be interpreted as meaning that 97% of all AI malware circulating worldwide is harmless.
Unit
In other words, the result describes this research dataset and its observed production exposure.
It does not represent a global census of every AI-enabled malware sample.
That distinction matters when interpreting cybersecurity statistics.
Only 12 Samples Reached Protected Endpoints
Of the 405 samples examined, 12 were observed on Cortex XDR-protected endpoints.
Unit 42 said those samples represented several different malware families and AI-related techniques, including FunkSec ransomware, a trojanized AI application, Oyster, Rhadamanthys and a COM-hijacking DLL.
The researchers also reported that their products detected and blocked every sample that attempted to reach a customer environment.
This suggests that existing defensive technologies can still be effective against AI-assisted malware.
AI Does Not Automatically Defeat Traditional Security
One of the most interesting conclusions from the research is that AI-assisted malware does not necessarily require an entirely new defensive model.
The AI component may influence how the malware is written or how certain decisions are made, but once malicious code executes on a system, it still has to perform observable actions.
It may create files.
It may modify registry settings.
It may launch processes.
It may communicate over networks.
It may attempt credential theft.
Those behaviors can still be detected.
The Real Advantage for Attackers Is Speed
The bigger threat may therefore be velocity.
An attacker who can produce ten malware variants in the time previously required to produce one has more opportunities to test defenses, evade signatures and experiment with new techniques.
Even if most experiments fail, the cost of experimentation is falling.
That could eventually create a larger population of effective malware.
The cybersecurity industry should therefore pay close attention not only to how sophisticated AI malware is today, but also to how quickly its development cycle is improving.
Deep Analysis
Identity Is Becoming the New Perimeter
The Snowflake development illustrates a fundamental change in enterprise security.
Organizations once focused heavily on protecting network boundaries. Today, attackers increasingly target identities, credentials, tokens and permissions.
A valid identity can sometimes provide more useful access than an exploited vulnerability.
That makes identity security one of the most important components of modern cloud defense.
Static Secrets Create Long-Term Exposure
A password can remain valid for months or years.
If that password is stolen and nobody notices, an attacker may have an extended opportunity to use it.
Federated authentication and short-lived credentials reduce that window.
Even if a token is compromised, its usefulness can be limited by expiration, scope and additional policy controls.
Service Accounts Deserve Human-Level Security Attention
Organizations sometimes treat service accounts as technical plumbing rather than security-sensitive identities.
That approach is increasingly dangerous.
A service account may have access to databases, production systems, cloud storage or sensitive analytics environments.
In some cases, its privileges can exceed those of ordinary employees.
That makes poorly managed service accounts attractive targets.
Inventory Comes Before Migration
Companies cannot secure identities they cannot see.
Before eliminating passwords, organizations need a reliable inventory of service accounts, applications, owners, privileges, authentication methods and dependencies.
The migration process should begin with visibility.
Only after understanding the environment can security teams safely redesign authentication.
Least Privilege Becomes More Important
Removing passwords is valuable, but it does not solve excessive permissions.
If a service account is passwordless but can still access an entire production database, compromising that identity could remain devastating.
Authentication and authorization therefore have to evolve together.
The strongest model combines strong identity verification with minimal permissions.
AI Agents Will Multiply the Identity Problem
The emergence of AI agents creates another challenge.
A company may soon have hundreds or thousands of automated agents performing tasks on behalf of employees and applications.
Each agent may need its own identity, permissions, credentials and audit trail.
Without proper controls, organizations could replace human password sprawl with AI-agent identity sprawl.
Every Agent Needs a Clear Scope
An AI agent should not automatically inherit broad permissions simply because it is part of a trusted application.
Its access should be limited to the resources required for its assigned task.
If an agent only needs to read a particular dataset, it should not receive unrestricted database administration privileges.
This principle becomes increasingly important as autonomous software becomes more common.
AI Malware and AI Agents Create Opposite Security Pressures
There is an interesting symmetry here.
Attackers are using AI to accelerate offensive development.
Defenders and businesses are simultaneously deploying AI agents to automate legitimate work.
Both sides are increasing the number of automated processes operating in digital environments.
That means identity management becomes even more important.
Automation Requires Accountability
An automated process can execute actions much faster than a human.
That is useful when the action is legitimate.
It is dangerous when the process has been compromised.
Security teams therefore need detailed audit trails showing which identity performed an action, which application initiated it, what permissions were used and what data was accessed.
AI Does Not Remove the Need for Conventional Security
The Unit 42 findings reinforce an important point.
Organizations should not abandon endpoint detection, behavioral analytics, sandboxing, network monitoring or traditional security controls simply because malware now incorporates AI.
Those technologies remain valuable because malicious software still has to interact with the operating system and network.
Detection Still Has a Behavioral Advantage
Code can change rapidly.
Behavior is often harder to hide.
An attacker may rewrite malware using AI, but if the resulting program still performs suspicious credential theft, persistence or command-and-control activity, behavioral defenses can potentially identify it.
This is one reason AI-assisted malware does not automatically represent an entirely new defensive problem.
The Bigger Concern Is Scale
AI’s most consequential impact may be the ability to scale experimentation.
A small criminal group can potentially generate, test and modify more code than it could previously.
That increases the number of attempts an organization may face.
Cybersecurity teams therefore need automation of their own.
Manual analysis will become increasingly difficult when attackers can produce threats at machine speed.
Security Teams Need Their Own Automation
Automated detection, automated containment and automated identity controls will become increasingly important.
The goal is not to respond to every event manually.
The goal is to identify high-confidence threats quickly and limit their ability to spread.
The more attackers automate, the more defenders must automate.
Snowflake’s Timeline Is Significant
Snowflake’s current rollout is scheduled for August through October 2026.
During this phase, existing human password users will be subject to stronger authentication requirements, while legacy service users will be blocked from password authentication and transitioned toward the newer service-user model.
This means the issue is no longer theoretical.
Organizations using affected authentication methods need to prepare for enforcement.
The Migration Could Expose Hidden Dependencies
One of the most underestimated risks during authentication modernization is operational disruption.
An old password may be buried inside a script, integration or application that nobody remembers.
Changing it can break production workloads.
That is why identity modernization should be treated as an engineering project rather than a simple security configuration change.
Ownership Should Be Mandatory
Every service identity should have a responsible team or individual.
The organization should know why the account exists, what it connects to, what permissions it has and when it should be reviewed.
Unknown accounts should not remain indefinitely active simply because nobody wants to risk breaking something.
Credentials Should Have an Expiration Strategy
Long-lived credentials create long-lived risk.
Organizations should favor authentication methods that automatically rotate, expire or derive credentials dynamically.
The objective is to reduce the value of stolen secrets.
Security Teams Should Watch for Credential Abuse
Organizations should monitor unusual authentication patterns, unexpected locations, abnormal access times and unusual data activity.
A legitimate account behaving abnormally can be just as important as malware detection.
Identity telemetry should therefore be integrated into the broader security monitoring system.
Cloud Security Is Becoming Identity Security
Cloud platforms have changed where valuable assets live.
Data is no longer necessarily protected by a physical network perimeter.
Applications, identities and permissions now determine who can access critical resources.
That makes identity configuration one of the most important cloud-security decisions an organization can make.
AI Makes Good Identity Hygiene Even More Important
AI can accelerate both legitimate automation and malicious activity.
If credentials are poorly protected, automated attackers can potentially exploit them faster.
If identities are strongly controlled, narrowly scoped and continuously monitored, automation becomes easier to manage safely.
The security architecture has to assume that both humans and machines can make mistakes.
The Future Will Be Password-Light, Not Risk-Free
Eliminating passwords does not eliminate cyberattacks.
It removes one particularly fragile authentication mechanism.
Organizations will still have to protect identity providers, tokens, certificates, federation systems, endpoints and administrative accounts.
Passwordless security is a stronger foundation, but it is not a complete security strategy.
The Real Lesson From These Two Stories
Snowflake and Unit 42 are addressing different parts of cybersecurity, but they reveal the same underlying trend.
The industry is moving toward systems where identity, automation and behavior matter more than static secrets and simple signatures.
Attackers are becoming faster.
Defenders must become more adaptive.
What Undercode Says:
Credential Theft Is Becoming More Dangerous
The most important development in the Snowflake story is not simply the removal of passwords. It is the recognition that legitimate credentials can become weapons when attackers obtain them.
A valid credential can bypass many assumptions built into traditional security models.
Passwordless Authentication Is a Strategic Move
Moving service accounts away from passwords is a logical step for cloud security.
Long-lived secrets are difficult to manage safely at enterprise scale.
Federated and workload-based authentication can reduce the amount of permanent credential material organizations must protect.
The Migration Problem Is Bigger Than Authentication
Companies should not treat
The real challenge is discovering every dependent workload and determining which identity should authenticate it.
That requires asset discovery, application mapping and ownership.
AI Malware Should Not Be Overhyped
Unit
AI-assisted malware is real, but the research does not show that hundreds of AI-powered attacks are successfully compromising organizations.
The majority of samples in the studied dataset remained outside production environments.
But the Threat Should Not Be Dismissed
The fact that most samples did not reach production does not mean the technology is irrelevant.
AI can still lower development barriers and accelerate malware iteration.
Today’s experimental malware could become tomorrow’s mature attack tooling.
Speed May Matter More Than Intelligence
AI does not need to create an autonomous super-malware strain to significantly affect cybersecurity.
If it allows attackers to develop, modify and test malware faster, it can still alter the economics of cybercrime.
That is potentially more important than flashy demonstrations.
Service Accounts Are High-Value Targets
Service accounts often operate quietly in the background while holding powerful privileges.
That combination makes them attractive targets.
Organizations should treat them as privileged identities, not disposable technical objects.
AI Agents Need the Same Discipline
As enterprises deploy AI agents, the same lessons apply.
Every agent needs an identity.
Every identity needs permissions.
Every permission needs a purpose.
And every important action needs an audit trail.
The Security Battle Is Moving Toward Control
The next generation of cybersecurity will be less about simply asking whether a user knows a password.
It will be about determining whether an identity, workload or AI agent is authorized to perform a specific action at a specific time under specific conditions.
Undercode’s Bottom Line
Snowflake’s password deprecation and Unit 42’s AI-malware research are not isolated stories.
They represent two sides of the same transformation.
Attackers are increasingly automating offensive activity while defenders are redesigning authentication around stronger, more contextual identities.
The organizations that adapt fastest will be the ones that know exactly who and what is accessing their systems.
✅ Fact: Snowflake is deprecating password authentication for service users and is rolling out stronger authentication requirements during August–October 2026.
✅ Fact: Unit 42 analyzed 405 AI-linked malware samples and observed 12 on Cortex XDR-protected production endpoints, with approximately 97% of the dataset not observed in production telemetry.
⚠️ Context: The 97% figure applies specifically to Unit 42’s 405-sample research dataset and should not be interpreted as a measurement of all AI malware worldwide.
Prediction
(+1) Snowflake’s move will likely accelerate the adoption of passwordless and federated authentication for service accounts across cloud data platforms.
(+1) Enterprise security teams are likely to place greater emphasis on service-account inventories, identity ownership and least-privilege access as automated workloads continue to expand.
(+1) AI-assisted malware development will probably increase the number and speed of malware experiments, even if most generated samples continue to fail against real-world defenses.
(+1) AI agents will become a major new identity-management challenge, forcing companies to create dedicated controls for non-human and autonomous identities.
(-1) Organizations that delay migrating legacy service accounts could face operational disruption when password authentication is eventually disabled, particularly when undocumented applications depend on old credentials.
(-1) The number of AI malware samples circulating publicly may continue to create misleading impressions about the scale of successful AI-powered attacks unless researchers distinguish experimental samples from confirmed production compromises.
The broader prediction is clear: the cybersecurity battlefield is moving from passwords toward identities, permissions, automation and behavioral trust. Attackers are using AI to move faster, while defenders are being forced to build systems that can determine not only who is accessing a resource, but why, how, and whether that access should be allowed at all.
