Case Study on Stopping Russian Hackers

This case study documents the investigation and resolution of a significant security breach involving Russian hackers targeting a finance industry client. The issue began with frequent account lockouts that were previously dismissed by the client's former managed service provider (MSP). Upon taking over, iuvo's team identified gaps in the client's legacy IT setup and began analyzing logs to determine the root cause. They discovered that a computer on the network was attempting unauthorized logins using randomly generated usernames. By adjusting logging settings, iuvo gained visibility into the attacks and determined that the computer was directly connected to the Internet without adequate security measures. A specialized forensics team was brought in to assess the extent of the breach, revealing multiple compromised servers. iuvo implemented immediate security measures to mitigate the risks and prevent future incidents, ultimately ensuring the client's systems were secured and productivity restored.
