7. The method of claim 5 , further comprising:

receiving, by the storage system, confirmation from the remote system indicating that the remote system has determined, based on the analysis of the storage operation requests of the storage system, that the data stored by the storage system is being targeted by the attack; and

performing, by the storage system in response to the receiving of the confirmation, an additional remedial action.

8. The method of claim 1 , wherein the receiving of the attribute data comprises receiving the attribute data from a remote system by way of a network.

9. The method of claim 8 , wherein the remote system is in communication with a plurality of storage systems and configured to generate the attribute data based on an analysis of storage operation requests with respect to the plurality of storage systems.

10. The method of claim 1 , wherein the receiving of the attribute data comprises receiving the attribute data directly from the target system by way of a network.

11. The method of claim 1 , wherein the updating of the extensible attack monitoring process comprises dynamically updating the extensible attack monitoring process as the extensible attack monitoring process is being executed by the storage system.

12. The method of claim 1 , wherein the attribute data comprises data representative of a pattern associated with the known attack, a compressibility of data being written to the target system, or a format of data being written to the target system.

13. The method of claim 1 , wherein the monitoring for the one or more attributes of the storage operation requests that match the one or more attributes of the known attack comprises determining that the one or more attributes of the storage operation requests satisfy a similarity threshold with respect to the one or more attributes of the known attack.

14. The method of claim 1 , wherein the known attack comprises an encryption attack against the data stored by the target storage system.

15. A method comprising:

receiving, by a storage system from a remote system communicatively coupled to the storage system and a plurality of storage systems other than the storage system by way of a network, attribute data representative of one or more attributes of a known attack against data stored by a system other than the storage system, the attribute data generated based on an analysis of storage operation requests with respect to the plurality of storage systems other than the storage system;

using, by the storage system, the attribute data to detect one or more attributes of storage operation requests with respect to the storage system that match the one or more attributes of the known attack;

determining, by the storage system based on the detecting that the one or more attributes of the storage operation requests match the one or more attributes of the known attack, that data stored by the storage system is possibly being targeted by an attack;

maintaining, by the storage system, historical attribute data representative of one or more attributes of the storage operation requests with respect to the storage system over time that precedes an attack against the data stored by the storage system that was not detected during the determining, the historical attribute data comprising data representing one or more of: an identifier of a specific storage operation, a timing of the specific storage operation, a pattern of occurrence of the specific storage operation, or an analysis of data corrupted by the attack; and

transmitting, by the storage system to a remote system and based on a recognition of an occurrence of the attack that was not detected during the monitoring, the historical attribute data for analysis by the remote system.

16. The method of claim 15 , wherein the using the attribute data comprises updating, by the storage system, an extensible attack monitoring process executed by the storage system with the attribute data.

17. A system comprising:

a memory storing instructions;

a processor communicatively coupled to the memory and configured to execute the instructions to:

receive, from a remote system communicatively coupled to the system and a plurality of storage systems other than the system by way of a network, attribute data representative of one or more attributes of a known attack against data stored by a target system other than the storage system, the attribute data generated based on an analysis of storage operation requests with respect to the plurality of storage systems other than the system;
