Techniques for detecting exfiltration content are described herein. According to one embodiment, a malicious content suspect is executed and a packet inspection of outbound network traffic is performed by a packet inspector running within the virtual machine. Occurring before the outbound network traffic leaving the virtual machine, the packet inspector determines whether a portion of outbound network traffic matches one or more portions of predetermined network traffic patterns or signatures. If so, a determination is made whether the outbound network traffic includes at least one environmental property of the virtual machine that is unique or almost unique to the virtual machine. If so, migration of the outbound network traffic outside of the virtual machine is precluded and an alert is transmitted. The alert includes the malicious content suspect that is attempting to perform an exfiltration of data.

System and method for detecting exfiltration content

Techniques for detecting malicious behavior of content (object) are described herein. An object is processed within a virtual machine. Responsive to receiving the result of the processing (response object), a parser parses the response object into a plurality of sub-objects. The plurality of sub-objects include a first sub-object and a second sub-object. A first behavior match result is determined based, at least in part, on whether information within the first sub-object corresponds to a identifiers associated with malicious activity. Also, a second behavior match result is determined based, at least in part, on whether information within the second sub-object corresponds to identifiers associated with malicious activity. Thereafter, the first and second behavior match results are aggregated to produce an aggregated result, wherein a malicious behavior score is calculated based, at least in part, on the aggregated result. The object is classified according to the malicious behavior score.

System and method for classifying an object based on an aggregated behavior results

System and method for detecting malicious activity based on at least one environmental property

Techniques for detecting exfiltration content are described herein. According to one embodiment, a malicious content suspect is executed within a virtual machine that simulates a target operating environment associated with the malicious content suspect. A packet inspection is performed on outbound network traffic initiated by the malicious content suspect to determine whether the outbound network traffic matches a predetermined network traffic pattern. An alert is generated indicating that the malicious content suspect should be declared as malicious, in response to determining that the outbound network traffic matches the predetermined network traffic pattern.

Techniques for detecting malicious behavior of content or objects are described herein. According to one embodiment, a malicious content suspect is executed within a virtual machine that simulates a target operating environment associated with the malicious content suspect. A communication response object is received as a result of processing the malicious content suspect. A first behavior match result for a first sub-object of the communication response object is determined. A second behavior match result for a second sub-object of the communication response object is also determined. The first and second behavior match results are aggregated and a malicious behavior score is calculated according to the aggregated result from all matches. The malicious content suspect is classified according to the malicious behavior score.

Described herein are devices, systems, and methods for determining the composition of fluids, and particularly for describing the identity and concentration of one or more components of a medical fluid such as intravenous fluid. These devices, systems and methods take multiple complex admittance measurements from a fluid sample in order to identify the identity and the concentration of components of the fluid. The identity and concentration of all of the components of the solution may be simultaneously and rapidly determined. In some variations, additional measurement or sensing modalities may be used in addition to admittance spectroscopy, including optical, thermal, chemical, etc.

Intravenous fluid monitoring

Fluid sensor methods and systems adapted for monitoring and/or controlling distillation operations in fluidic systems, such as batch distillation operations or continuous distillation operations, are disclosed. Preferred embodiments are directed to process monitoring and/or process control for unit operations involving endpoint determination of a distillation, for example, as applied to a liquid-component-switching operation (e.g., a solvent switching operation), a liquid-liquid separation operation, a solute concentration operation, a dispersed-phase concentration operation, among others.

A flexural resonator includes a piezoelectric material. At least a portion of an electrode having a first surface and a second surface is embedded in the piezoelectric material such that the piezoelectric material is disposed over and in electronic association with the first and second surfaces of the electrode.

Flexural resonator sensing device and method

Methods for monitoring a fluid composition include placing a mechanical resonator in the fluid composition and oscillating the resonator. The resonator can be a tuning fork resonator having tines oscillated in opposite directions and in opposite phases. A variable frequency input signal can be varied over a predetermined frequency range and oscillate the mechanical resonator at less than 1 MHz. A frequency-dependent resonator response curve can be stored in a computer memory and fitted to a model curve to monitor the fluid. The resonator can be coated with a protective coating. The resonator can be treated with a functionality designed to change a resonance frequency of the resonator after being exposed to a selected target chemical and the resonance frequency monitored to detect presence of the target chemical.

A sensor for sensing one or more properties of a vehicle fluid has a tuning fork resonator adapted to contact the fluid. The tuning fork resonator comprises two tines and is operable to oscillate so that the two tines move in opposite phase at a frequency of less than 1 MHz while contacting the fluid to generate a resonator response indicative of one or more properties of the fluid. In another aspect, a sensor includes a substrate and a flexural resonator on the substrate and adapted to contact the fluid. Circuitry for operation of the resonator is on the substrate. The resonator is adapted to receive an input signal and to oscillate while contacting the fluid to generate a resonator response indicative of one or more properties of the fluid. One suitable application for the invention is monitoring the condition of a vehicle engine oil.
