A familiar face. A trusted voice. That’s all it took to open the door to a major retailer’s most sensitive systems.
It wasn’t malware or a zero-day exploit that compromised their Google Workspace. It was a social engineering attack, and we were behind it, posing as the retailer’s own Head of IT.
The breach didn’t start with code. It started with a conversation, built on urgency, authority, and just enough detail to sound legitimate.
This is a story about how social engineering slipped past every technical control. It’s proof the human element is still the easiest way in.

The scenario
Human manipulation often beats technical exploits. With just 48 hours of intelligence gathering, we found a path into an entire digital environment.
Our target: an employee holding the keys to the organisation’s crown jewels. Our method: social engineering, not malware.
Within days, we had full administrative access to their Google Workspace, the operational core of the business. A simple social engineering exercise had become complete control of their critical systems.
The challenge: a social engineering attack on Google Workspace
Modern cybersecurity isn’t just about strong passwords and firewalls. It’s about the human element.
Our mission: test whether the retailer’s defences could withstand a targeted social engineering attack aimed at their Google Workspace environment. The question wasn’t if we could get in. It was how quickly, and how thoroughly, we could take control using nothing but human-based tactics.
The approach
We started with reconnaissance. For two days, we ran meticulous OSINT, open source intelligence gathering, sifting through publicly available information like digital detectives.
The breakthrough came from a Facebook data breach containing employee information. That intelligence pointed us to two promising contacts inside the organisation. Cross-checking their LinkedIn and Facebook profiles confirmed our primary target: the Head of IT.
Further digging surfaced a critical detail. Staff had listed Slack as a communication tool on their LinkedIn profiles, showing us exactly how the internal team talked to each other.
The narrative
We built a story: a suspected cyber breach requiring immediate action. Using spoofed contact information, we reached our target with urgency, telling them to avoid discussing the “internal threat” with colleagues.
We convinced them to log out of Slack, cutting them off from any chance to verify our story with coworkers. Then came the tipping point: we persuaded them to reset their Google Workspace password and hand it to us for “system cleansing.”
To keep our access, we added a second phone number to their authentication portal. That gave us a standing backdoor into their critical applications.
The breach
The compromise came fast. With the password in hand and a second authentication method already in place, we took full administrative control of the retailer’s Google Workspace environment: documents, calendars, contacts, and every business application tied to it.
What made this breach dangerous was its stealth. The target believed they were helping their own IT leadership shut down a threat. They never realised they had created one.
Isolating them from their normal communication channels removed any chance that a colleague might have caught the ruse. It’s a clear look at where Google Workspace security actually breaks: not in the platform’s controls, but in the human decision to trust an urgent voice on the phone.
The outcome
In under a week, using nothing but publicly available information and persuasive conversation, we gained complete administrative control over a business-critical system.
We set up persistent access. A real attacker with that access could have run ongoing surveillance, stolen data, or moved deeper into the network. Our reconnaissance also surfaced physical-location intelligence that never appeared in the retailer’s public records, a reminder that OSINT rarely stays confined to the digital surface.
The retailer’s systems weren’t compromised by sophisticated malware or a zero-day exploit. They were compromised because nobody verified that the voice on the phone was who it claimed to be.
Most identity checks still run on tone and detail, not on a verified callback, and that gap is what let us in.
What if?
What if this hadn’t been us? A real attacker could have kept that access indefinitely, pulling customer data, financial records, or intellectual property without ever tripping an alarm.
Constant threat demands constant, targeted defence. The gap between perceived risk and actual exposure is where the damage happens, financial loss, reputational damage, business disruption, and it’s avoidable with the right pressure applied first.
What would an attacker find if they targeted you today?
This breach didn’t hinge on a technical flaw. It hinged on one moment: nobody verified that the person asking for a password reset actually was who they claimed to be.
That’s the gap the Swarm is built to find before a real adversary does. We test whether your team can spot a spoofed identity under pressure, not just whether your firewall holds.
Don’t wait to find out how your people respond to a convincing lie. Contact CovertSwarm to put your verification processes under constant, targeted attack, and close the gap before someone else finds it.
