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.

The client with the bank system requested to perform a penetration testing against his system. The test scope for this engagement included a businesscritical web application on AWS cloud web hosting, company's internal network, as well as a company's Security Information and Event Management (SIEM) system.

• Perform penetration tests on the systems
• Create new testing methods to identify vulnerabilities
• Pinpoint methods and entry points that attackers may use to exploit vulnerabilities or weaknesses
• Search for weaknesses in common software, web applications and proprietary systems
• Research, evaluate, document and discuss findings with IT teams and management
• Review and provide feedback for information security fixes
• Establish improvements for existing security services, including hardware, software, policies and procedures

Identify areas where improvement is needed in security education and awareness for users

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.
