## Abstract

Technology descried here can be used for collecting information about malicious attacks on computer devices. Hosting hardware can be configured to host virtual machines, virtual machines of ECU images, and ECUs to collect records of malicious attacks. An attack analyzer can generate fingerprints from the malicious attacks.

## Claims

### Claim at position 1

1-20. (canceled)

### Claim 21

A non-transitory computer readable medium including instructions that, when executed by at least one processor, cause the at least one processor to perform operations for two-factor validation for computer-assisted vehicle functions, comprising:
receiving, from a real time sensor in a vehicle, sensor data collected by the sensor during operation of the vehicle and relating to a sensed environmental characteristic;
identifying a potential computer-assisted vehicle function to be performed in the vehicle based on the sensor data;
accessing, before the potential computer-assisted vehicle function is allowed to occur, a source of validation information external to the vehicle, wherein the source of validation information also relates to the environmental characteristic; and
determining whether the sensed environmental characteristic corresponds to the validation information; and
based on the determining, either:
permitting the computer-assisted vehicle function to occur when the sensed environmental characteristic corresponds to the validation information; or
sending a report to a reporting service when the sensed environmental characteristic does not correspond to the validation information.

### Claim 22 (depends on 21)

The non-transitory computer readable medium of claim 21, wherein the sensed environmental characteristic is a detected object.

identifying a potential computer-assisted vehicle function to be performed in the vehicle based on the sensor data;
accessing, before the potential computer-assisted vehicle function is allowed to occur, a source of validation information external to the vehicle, wherein the source of validation information also relates to the environmental characteristic; and
determining whether the sensed environmental characteristic corresponds to the validation information; and
based on the determining, either:
permitting the computer-assisted vehicle function to occur when the sensed environmental characteristic corresponds to the validation information; or
sending a report to a reporting service when the sensed environmental characteristic does not correspond to the validation information.

### Claim 32 (depends on 31)

The computer-implemented method of claim 31, wherein the sensed environmental characteristic is a detected object.

### Claim 33 (depends on 31)
