Worst AWS Data Breaches of 2021

3 mins to read

Data breaches remain a challenge despite an increase in cybersecurity awareness and investments. This past year, 2021, has been a particularly dire year for cloud breaches, with incidents taking down networks for weeks at a time, and disrupting business throughout the country.

While AWS is an increasingly adopted tool that enables enterprises to upload and distribute data with unmatched effectiveness, it comes with a unique set of vulnerabilities overlooked by users. Misconfigured S3 buckets can present serious risks to your cloud environment, often without you even realizing it. To get specific, public read access could lead to a data breach, while public write access can launch malware or encrypt data to hold your company ransom.

Attacks on these vulnerabilities don’t look like they are slowing down any time soon. Getting access to data, your company’s most valuable asset is big business. You have bad actors asking for ransom and selling data online with organizations and governments offering rewards to take down these cybercriminals.  

In July, the State Department announced a $10 million reward for any information about hackers working for foreign governments aimed squarely at those participating in “malicious cyber activities against US critical infrastructure in violation of the Computer Fraud and Abuse Act.” Following this effort, the US government put up a $15 million reward for tracking down the individuals in the DarkSide organization in August. 

Happening simultaneously, 3.3 million Volkswagen & Audi records were for sale online. An unnamed marketing services company was responsible for the breach of these Volkswagen and Audi customers and prospects in Canada and the U.S., because of unsecured data. 

These were just a few of the top examples from 2021. Below we highlight a few of last year’s most notable breaches.

In summary, a majority of recent high-profile cloud breaches involved misconfiguration, low visibility, and privilege abuse as the leading causes of cyberattacks. These platform vulnerabilities have subjected enterprises to cyberattacks from insider threats, weak authentication, and third-party access, leading to severe financial and human implications.

Modern enterprises require a shift in cloud security strategy that emphasizes improved configuration procedures, management of proliferating identities and entitlements, and streamlined data classification.
