WhoAMI Attack: The AWS Vulnerability That’s Not Who You Thought It Was!

The whoAMI attack allows hackers to execute arbitrary code within AWS accounts by publishing a cleverly named Amazon Machine Image (AMI). Researchers warn that this could impact thousands of accounts. AWS has implemented new controls to combat this, but vulnerable organizations should act fast to avoid an unwanted surprise in their cloud.

Hot Take:

Who knew that a little identity crisis could cause such a big fuss? Looks like AWS needs to go to therapy for its AMI-ssues! This whoAMI attack shows us that if AWS accounts were a sitcom, they’d definitely be in an episode titled “The One Where AMI Gets Confused.”

Key Points:

  • WhoAMI attack allows arbitrary code execution in AWS accounts via AMI name confusion.
  • About 1% of organizations could be vulnerable to this new attack technique.
  • Attackers exploit the absence of owner specifications to publish malicious AMIs.
  • AWS has introduced controls to prevent such attacks, including Allowed AMIs.
  • HashiCorp has also addressed the issue in its AWS provider updates.
