Exposed AWS credentials are turning ordinary developer mistakes into wide-open doors for attackers, and the latest numbers show just how widespread the problem has become. There’s a version of “getting hacked” that involves zero-days, custom malware, and a skilled adversary probing for weeks to find a way in. Then there’s the version making headlines right now: a company accidentally leaves the keys to its entire cloud environment sitting in a public code repository, and anyone who happens to look finds them.
That’s the story behind a new report from Truffle Security, and it’s a wake-up call every business using cloud infrastructure needs to hear.
The Numbers Are Staggering
Truffle Security spent four years scanning public code repositories, Git history, Docker images, container registries, and CI/CD logs for exposed Amazon Web Services (AWS) credentials. What they found should concern any organization that runs on the cloud—which, today, is nearly everyone:
- 431,875 AWS secrets discovered scattered across public sources
- 64,024 unique AWS keys, tied to over 50,000 AWS accounts
- 9,300+ of those keys are still active today—meaning they still work, right now, for anyone who finds them
- 817 keys were tied to identifiable companies, and 526 of those were root keys—the master credentials with no restrictions at all
- 242 keys belonged to IAM users with full Administrator Access—total, unrestricted control over the AWS account
Put simply: hundreds of companies have, right now, a working master key to their entire cloud environment sitting exposed on the public internet—and most of them likely have no idea. These exposed AWS credentials represent one of the most preventable yet persistent risks in modern cloud security.
This Isn’t Sophisticated Hacking. It’s an Open Door.
What makes this trend so alarming isn’t the complexity of the attack—there isn’t any. A leaked AWS key doesn’t require exploiting a vulnerability, writing custom malware, or social-engineering an employee. It requires nothing more than an attacker running an automated scanner against public code repositories and waiting for a hit.
Once an attacker has one of these keys, they can:
- Access, steal, or permanently delete cloud-hosted data
- Take control of servers and applications running in that environment
- Create hidden admin accounts to maintain long-term, persistent access
- Spin up cryptomining operations on the company’s dime—quietly generating massive cloud bills
And that last point matters more than it sounds: Truffle Security found that only 262 of 2,754 accounts they could inspect had even a basic budget alert configured. That means most companies wouldn’t notice unauthorized cloud usage until the bill arrived—or until something worse happened first. In many cases, the presence of exposed AWS credentials turns what should be a minor operational issue into a full-blown security incident with financial and reputational consequences.
The Real Root Cause: Nobody’s Cleaning Up Exposed AWS Credentials
Perhaps the most telling statistic in the entire report is this: among the keys with a known creation date, the median age was 1,831 days—about five years old. Only 13.7% had ever been rotated with a newer key.
These aren’t fresh mistakes. These are credentials that were leaked, forgotten, and left to sit—often for half a decade—with nobody ever circling back to check if the door was still unlocked. That’s not a hacking problem. That’s a hygiene problem. And it’s exactly the kind of gap that separates companies with a real security program from companies that are hoping nothing bad happens. Organizations that fail to systematically hunt for and revoke exposed AWS credentials are essentially leaving permanent invitation cards for attackers on the public internet.
What This Means for Your Business
If your development team uses AWS—and if you build, host, or run anything in the cloud, they almost certainly do—this report is a direct warning, not just an interesting read. A single hardcoded key committed to a repository, a forgotten root credential in an old script, or a set of secrets baked into a Docker image can be the entire difference between a secure environment and a wide-open one. The continued discovery of exposed AWS credentials underscores how easily day-to-day development practices can create long-lived security debt.
The fix isn’t exotic. It’s basic cloud hygiene, done consistently:
- Eliminate root access keys entirely. Root credentials should never be used for day-to-day operations.
- Audit IAM credentials by age. If nobody knows how old a key is, nobody knows how exposed it might be.
- Rotate or revoke exposed credentials immediately—and treat anything ever committed to a public repository as compromised, full stop.
- Set budget alerts on every cloud account, so unusual activity gets flagged before it becomes a five-figure surprise.
- Scan repositories and CI/CD pipelines continuously for secrets before they ever reach a public commit.
Beyond these core practices, teams should also review historical Git commits, container layers, and CI/CD logs for lingering secrets. Automated secret-scanning tools can catch many issues early, but human review and clear ownership of credential lifecycle management remain essential. Regular tabletop exercises that include the scenario of leaked cloud keys can also help organizations test their detection and response capabilities before a real incident occurs.
The Bottom Line
Attackers don’t need to be sophisticated when companies leave the door open for five years at a time. This is precisely the kind of exposure that a proactive security partner catches—before it becomes a headline with your company’s name in it. Addressing exposed AWS credentials is not a one-time project; it requires ongoing vigilance, clear processes, and a culture that treats secrets as carefully as production data.
At Black Belt Secure, our JUTSU program is built to find exactly these kinds of gaps—exposed credentials, misconfigured cloud environments, and forgotten access points—before an attacker does. If it’s been a while since anyone audited your cloud credentials, now is the time.
