During a penetration test of cryptocurrency website, a critical vulnerability was found. This vulnerability allowed to get all confidential information about the users, including emails, wallets and balances, etc. knowing user ID. The vulnerability was amplified with the fact that it was easy to generate all possible IDs with own written script. Our team helped to fix this vulnerability as soon as it was found.
- analyze the system and prepare scope of work
- gather information about the system
- check used services and their versions
- find exploits for these services
- test api and requests to the server
- get access to the database
- prepare a detailed report on found vulnerabilities including executive summary, risk level of each vulnerability and recommendations on how to fix them.
Curl, Burp Suite, Requests interception, modification, injections of malicious code, own written bash script to brute force user ID values.
An enterprise company requested DDoS protection and full security audit of the website on AWS managed with Kubernetes. At the time of DDoS attacks Kubernetes scaled used resources up to 8 servers. However, even this scaling did not help agains the attacks. So our team has configured proper security rules, managed WAF and firewall and has written own solution. After this complex approach any attack could not harm the system.
