How to ensure your AWS account is not compromised

Imagine your AWS account as a magnificent cloud castle, brimming with valuable resources. Just like any castle, though, it needs strong defenses to ward off invaders.

Unfortunately, these invaders can be more than just fire-breathing dragons in the digital age. Compromised access keys, for instance, can be the chink in your armor, allowing unauthorized access and potentially causing significant damage.

This blog post is your guide to fortifying your cloud castle and ensuring you don’t experience the pain of having your AWS account hacked.

Don't let your AWS account become a target for a digital siege!

What happens when your AWS gets compromised

You log into your AWS console, ready to review the monthly bill. A wave of dread washes over you as you see a shockingly high figure. Your heart sinks as you realize the worst: your AWS account has been compromised.

And that can lead to all sorts of business stopping, teeth-gnashing results:

  • surprise! exorbitant AWS bill
  • lots of downtime for customers
  • business headaches and sleepless nights
  • scrambling to fix what’s been broken
  • dev time pulled from business to fix this fire
  • possibly loss of customers because of the downtime
  • loss of faith in your product’s ability to perform

And if security was one of your core selling points? Well that’s probably out the window now.

How does an AWS account hack happen?

Imagine your well-maintained castle has a single, unlocked back gate. That's how a compromised AWS account can feel and how you might end up with an AWS account hacked bill!!

There are many ways attackers can breach your defenses, but here are some of the most common culprits:

1. Weak passwords and unprotected keys

Just like your front door, a strong password and access keys are the first lines of defense. Treat them like your castle keys, keep them secure and don't share them unnecessarily. Rotate your access key secrets often and use IAM roles instead of long lived access keys.

2. Phishing attacks

Those deceptive emails or messages can be surprisingly effective and steal your credentials or download malware onto your device.

3. Exploiting IAM misconfigurations

You can control who can access your AWS resources via Identity and Access Management. For instance, IAM roles or users with overly broad permissions can potentially access and manipulate sensitive resources. Similarly, attackers can use compromised credentials to assume IAM roles and gain unauthorized access. Finally, without proper logging and monitoring, it can be difficult to detect and respond to unauthorized activity.

4. Malware

Sneaky software or malicious websites can steal your credentials or implant backdoors into your system, providing attackers with ongoing access.

5. Insider threats

Unfortunately, not all threats come from outside. Disgruntled employees or compromised accounts with insider access can also pose a risk.

What to do if your AWS is compromised

So, you suspect your AWS account might be compromised? Don't panic!

Regain control with this battle plan:

1. Act fast!

  • Rotate your Root User credentials, instead of using old passwords
  • Disable and revoke any compromised/suspicious access keys and create new ones.
  • Enable MFA. Think of it as a guard checking IDs at the gate.

2. Investigate the breach

Check CloudTrail logs that track your account activity in your account. Look for:

  • Unusual login attempts
  • Unauthorized resource access

3. Secure your account

  • Review IAM policies to ensure user permissions are set correctly and no one has excessive access.
  • Enable AWS security services, like GuardDuty. Think of them as additional guards patrolling your castle grounds.

4. Report the incident

Let AWS Support know what happened and seek further assistance. In most cases, they will refund you for the huge bill the hacker's run up.

How to prevent your AWS account from being hacked so this doesn’t happen to begin with (step by step)

Don’t want your AWS account compromised? Then take these precautions:

  • Never use the root user: It's like giving someone the keys to the city.
  • Create an IAM Identity Center: for centralized user management and a more secure way to log in using single sign-on (SSO) options like Google Suite or Office 365.
  • Designate IAM roles that provide temporary security credentials, reducing the risk of exposure.
  • Work with short-lived credentials
  • Enable MFA
  • Monitor user activity
  • Regularly review IAM policies to ensure users have only the necessary permissions to perform their jobs.
  • Patch and update your software and operating systems to address security vulnerabilities.
  • Educate your team about security best practices and the risks of phishing attacks.
  • Scan your AWS environments with Prowler for misconfigurations
