      <description>&lt;p&gt;Paige Thompson was accused of breaking into a Capital One server and gaining access to 140,000 Social Security numbers, 1 million Canadian Social Insurance numbers and 80,000 bank account numbers. &lt;/p&gt;

&lt;p&gt;Paige had exploited a Server Side Request Forgery vulnerability (SSRF) to invoke the AWS meta-data endpoint and subsequently steal authentication tokens to gain access to Capital One's internal network. &lt;/p&gt;

&lt;p&gt;The following interactive tutorial is a reconstruction of this data breach incident that exposed the records of almost 106 million customers, how Paige exploited this vulnerability and steps developers can take to mitigate against SSRF vulnerabilities.&lt;/p&gt;

      <description>&lt;p&gt;The recent investigation conducted by Checkpoint Research against TikTok highlights trivially-exploitable security issues, that could have allowed motivated threat actors to gain an understanding and/or manipulate their political adversaries Ad campaigns.&lt;/p&gt;

&lt;p&gt;To demonstrate the significance of this vulnerability, we at Kontra have developed an interactive tutorial detailing the Cross-Site Scripting flaw reported within TikTok's Ad platform and the exploitation of this issue by hypothetical cyber adversaries.&lt;/p&gt;

&lt;p&gt;The tutorial is designed to teach developers about how cross-site scripting attacks manifest in code, how malicious actors exploit these vulnerabilities and steps developers can take write secure code. &lt;/p&gt;
