The digital age has brought us countless conveniences, but it’s also opened doors to threats that would make spy novelists blush. This weekend, we witnessed another chapter in what’s becoming a disturbing trend: major corporations falling victim to surprisingly simple social engineering attacks. HR giant Workday, the trusted backbone of countless organizations’ human resources operations, just announced they’ve been hacked. But here’s the kicker – the attackers didn’t need sophisticated malware or complex zero-day exploits. They just picked up the phone.

The Phone Call That Started It All

Workday, one of the largest providers of human resources technology, has confirmed a data breach that allowed hackers to steal personal information from one of its third-party customer relationship databases. The company disclosed this breach in a blog post published late Friday, joining what appears to be a growing list of high-profile victims in a coordinated campaign.

What makes this attack particularly unnerving is its simplicity. The company said that a social engineering campaign had targeted its employees, with threat actors posing as IT or HR in order to trick employees into sharing account access or personal information. Think about it for a moment – in an era where companies spend millions on cybersecurity infrastructure, firewalls, and AI-powered threat detection systems, hackers succeeded by simply pretending to be someone they weren’t on a phone call.

The stolen data includes what security experts call “commonly available business contact information” – names, email addresses, and phone numbers. While this might sound relatively harmless compared to financial data or social security numbers, experienced cybercriminals know this information is pure gold for future attacks.

Meet the Puppet Masters: ShinyHunters Strike Again

This wasn’t a random attack by amateur hackers looking for quick cash. Security researchers have linked this breach to ShinyHunters extortion group, which has been using voice phishing attacks to steal data from Salesforce CRM instances. If that name sounds familiar, it should – this group has been making headlines for all the wrong reasons.

ShinyHunters is back, with low-tech hacks that nonetheless manage to bring down international megaliths like Google, Cisco, and Adidas. Their recent campaign reads like a who’s who of corporate America: Qantas, Allianz Life, LVMH, and Adidas have all fallen victim to similar attacks.

What makes ShinyHunters particularly dangerous isn’t just their technical skills – it’s their patience and persistence. ShinyHunters remained largely quiet between June 2024 and June 2025, following the arrests of four of its members, only to resurface with a vengeance in what appears to be a coordinated assault on Salesforce-based systems.

The Salesforce Connection: Why One Platform Matters So Much

You might be wondering why Salesforce keeps coming up in these attacks. The answer lies in how modern businesses operate. Salesforce isn’t just a customer relationship management (CRM) platform – it’s become the digital nervous system for countless organizations worldwide. Companies store everything from customer contact information to sales data, marketing campaigns, and even internal communications within their Salesforce instances.

These attacks are believed to have begun at the start of the year, with the threat actors tricking the targets’ employees into linking a malicious OAuth app to their company’s Salesforce instances through social engineering attacks. Once attackers gain access to a company’s Salesforce system, they essentially have the keys to the kingdom.

The technique is elegant in its simplicity. Hackers call employees, usually targeting those in IT or administrative roles, and pose as technical support staff. They create a sense of urgency – maybe there’s a security issue that needs immediate attention, or a system update that requires verification. The panicked employee, wanting to be helpful and resolve the supposed issue quickly, provides access credentials or authorizes the connection of a malicious application.

The Human Factor: Why Technology Isn’t Enough

What’s particularly sobering about the Workday breach is how it highlights the fundamental vulnerability in all cybersecurity systems: humans. Companies can deploy the most advanced security technologies available, implement multi-factor authentication, and train their IT teams in the latest threat detection methods. But all it takes is one well-timed phone call to the right person on a busy afternoon.

This technique is a form of social engineering attack known as voice phishing – or, simply, vishing. Unlike traditional phishing emails that many people have learned to spot, vishing attacks exploit our natural inclination to be helpful and trust authority figures, especially when they claim to represent our own organization’s IT department.

The attackers behind these campaigns do their homework. They research target companies thoroughly, learning the names of key personnel, understanding organizational structures, and timing their calls for maximum effectiveness. They might call during busy periods when employees are more likely to rush through verification procedures, or target new employees who may not be familiar with proper security protocols.

The Ripple Effect: Why This Matters to Everyone

You might think, “I don’t work for Workday, so this doesn’t affect me.” Unfortunately, that’s not how modern data breaches work. Workday provides HR services to thousands of organizations worldwide. While the company has stated that there is no indication of access to customer tenants or the data within them, the stolen contact information could be used to target employees at Workday’s client companies.

Here’s how it works: armed with legitimate business contact information, attackers can craft highly convincing phishing emails or phone calls to employees at other organizations. They can reference real people, actual business relationships, and current projects – all while attempting to steal additional data or gain access to other systems.

This creates a domino effect where one breach leads to another, and another, until what started as a simple phone call to one company becomes a massive, interconnected web of compromised data and systems.

The Bigger Picture: A Pattern of Simple Attacks, Massive Consequences

The Workday breach is part of a troubling trend in cybersecurity. While media coverage often focuses on sophisticated nation-state actors and advanced persistent threats, many of the most damaging attacks in recent years have relied on surprisingly basic techniques.

In 2024 it was Snowflake. In 2025 it’s Salesforce. Each year brings a new platform or service that becomes the focal point for coordinated attacks. What remains consistent is the human element – attackers succeed not because they’ve developed revolutionary new hacking techniques, but because they’ve mastered the art of manipulating people.

This pattern should concern every organization, regardless of size or industry. If companies like Workday, Google, and Adidas can fall victim to these attacks, no organization is too small or too large to be targeted.

Lessons Learned: What Organizations Must Do Now

The Workday breach offers several critical lessons for organizations of all sizes:

First, employee training must evolve beyond traditional phishing awareness. Most cybersecurity training programs focus on suspicious emails and malicious websites. However, vishing attacks require different skills and awareness. Employees need to understand that legitimate IT support rarely calls unexpectedly asking for immediate access or credentials.

Second, verification procedures must be standardized and enforced. Organizations should establish clear protocols for verifying the identity of anyone requesting access to systems or sensitive information, even if they claim to be from internal IT departments. This might include calling back through official numbers, requiring supervisor approval for unusual requests, or implementing specific code words or procedures for legitimate support requests.

Third, the principle of least privilege must be applied ruthlessly. The more access an individual has, the more damage a successful social engineering attack can cause. Organizations should regularly audit and minimize system access, ensuring employees have only the permissions necessary for their specific roles.

Fourth, incident response plans must account for social engineering attacks. Traditional cybersecurity incident response often assumes technical indicators of compromise – malware signatures, suspicious network traffic, or unauthorized system access. Social engineering attacks may leave fewer technical footprints, requiring organizations to develop new detection and response capabilities.

Looking Forward: The Evolution of Cybersecurity

The Workday breach and the broader ShinyHunters campaign represent a turning point in cybersecurity. As organizations have hardened their technical defenses, attackers have increasingly turned to exploiting human vulnerabilities. This shift requires a fundamental change in how we approach cybersecurity.

Future security strategies must recognize that technology alone cannot solve the cybersecurity challenge. The most advanced firewalls, intrusion detection systems, and artificial intelligence-powered threat analysis tools are only as strong as the weakest human link in the chain.

Organizations need to invest as heavily in human factors – training, procedures, culture, and psychology – as they do in technical security measures. This includes creating security-conscious cultures where employees feel comfortable questioning unusual requests, reporting suspicious contacts, and admitting mistakes without fear of punishment.

The Road Ahead

The Workday breach serves as yet another reminder that in our interconnected digital world, cybersecurity is everyone’s responsibility. While the immediate impact may seem limited – after all, the stolen data was “just” contact information – the long-term implications could be far-reaching.

As we move forward, organizations must grapple with a uncomfortable reality: the same technologies that make modern business possible – cloud platforms, integrated systems, and always-connected networks – also create unprecedented opportunities for attackers. The challenge isn’t just keeping pace with evolving threats, but fundamentally rethinking how we balance convenience, connectivity, and security.

The phone calls that led to the Workday breach may have lasted only a few minutes each, but their impact will be felt for months or years to come. In an age where a simple conversation can compromise millions of records, we all need to answer when cybersecurity calls – and make sure we’re ready for whatever’s on the other end of the line.

The next time your phone rings and someone claims to be from IT, remember Workday. Sometimes the most dangerous threats aren’t hiding in sophisticated code or advanced malware – they’re hiding in plain sight, pretending to be exactly who we expect them to be.
