The FBI has intervened to clean up the mess left by attacks on on-premise Microsoft Exchange Server installations after obtaining court orders to access hundreds of vulnerable machines in the US and remove Web shells.
In
a statement issued on Tuesday, the Department of Justice said these servers had been exploited in January and February by some groups who used zero-day vulnerabilities that Microsoft
publicised on 3 March.
More groups piled on in March while some of the earlier Web shells were removed by the owners, the statement said.
