Prerequisites

Clients’ company management was notified by the US Security Service about a planned targeted attack. Due to the USSS, the probable attackers goal was to steal digital tokens from the company or investors’ tokens. Few days later the CEO of the company became a victim of a SIM theft attack with identity theft, account takeover and attempt to compromise external services.

UnderDefense was involved to assess the current situation and help to make sure that the company assets are not at risk of being compromised.

Our Findings

Besides Covid-19 world-wide restrictions, part of the UD Incident Response team arrived on-site and along with our remote team, we performed a full-scope compromise assessment of the client’s infrastructure.

The assessment included real-time infrastructure monitoring with deep forensics back in time looking for signs of Advanced Persistent Threats.

During our investigation, we found both threat actor’s footprints and multiple Security Misconfigurations that may lead to probable compromisation. As a result of work, we prepared a detailed report with provided recommendations to improve clients’ cyber resilience state.

The Result

We have spotted multiple ongoing attacks, though none of them was successful and there were no signs of the active presence of malefactor actors and no active threats in the Client’s corporate environment.
