New malware created by Chinese-backed Winnti Group has been discovered by researchers at ESET while being used to gain persistence on Microsoft SQL Server (MSSQL) systems. The new malicious tool dubbed skip-2.0 can be used by the attackers to backdoor MSSQL Server 11 and 12 servers, enabling them to connect to any account on the server using a so-called “magic password” and hide their activity from the security logs.
