The cybercrime group FIN7 has been linked to numerous high-profile attacks against organizations such as Veeam. The group is known for its use of sophisticated tradecraft and malicious techniques. In a recent attack against Veeam backup servers, FIN7 used a multi-stage attack process to gain access and exfiltrate data.

The first stage of the attack involved using a backdoor to gain access to the network. This backdoor was likely planted on the server prior to the attack, either through an email phishing campaign or through a vulnerability in the server. Once the backdoor was installed, the attackers were able to gain access to the server and begin their reconnaissance.

The reconnaissance stage involved using a variety of techniques, such as scanning for open ports, mapping the network, and enumerating user accounts and passwords. The attackers then used a variety of tools and techniques to move laterally throughout the network and gain access to the Veeam backup servers.

Once the attackers had access to the Veeam servers, they used a modified version of the legitimate Veeam executable to create a backdoor and gain access to the server. This backdoor allowed the attackers to exfiltrate data from the server and also allowed them to execute arbitrary code.

FIN7 is known for its use of sophisticated tradecraft and malicious techniques. The group has been linked to numerous high-profile attacks, and its use of a multi-stage attack process to gain access to and exfiltrate data from Veeam servers is just one example of its capabilities. The group’s use of a backdoor, reconnaissance techniques, and a modified version of the legitimate Veeam executable to gain access to the server shows its level of sophistication and determination to achieve its goals. Organizations should be aware of the threat posed by FIN7 and take steps to protect their networks and data.
