Heuristic detection of malicious code
InactiveUS20090013405A1Avoid the needImprove the detection rateMemory loss protectionUnauthorized memory use protectionData fieldMalware
Scanning of computer files for malware uses a classifying technique to classify an input file as a clean file or a dirty file. The parameters of the classifying technique are derived to train the classification on a corpus of reference files including clean files known to be free of malware and dirty files known to contain malware. The classification is performed using a representation of the files in a feature space defined by a set of predetermined features for respective file formats, the features being a predetermined value or range of values for one or more data fields of given meanings. The representation of a file is derived by determining the file format, parsing the file on the basis of the structure of data fields in the determined file format to identify the data fields and their meaning, and determining, on the basis of the identified data fields, which of the set of predetermined features are present.

Malware detection using pattern classification
ActiveUS8161548B1Low false positive rateHigh percentageMemory loss protectionUnauthorized memory use protectionMalwareRelevant feature
A malware classifier uses features of suspect software to classify the software as malicious or not. The classifier uses a pattern classification algorithm to statistically analyze computer software. The classifier takes a feature representation of the software and maps it to the classification label with the use of a trained model. The feature representation of the input computer software includes the relevant features and the values of each feature. These features include the categories of: applicable software characteristics of a particular type of malware; dynamic link library (DLL) and function name strings typically occurring in the body of the malware; and other alphanumeric strings commonly found in malware. By providing these features and their values to the classifier, the classifier is better able to identify a particular type of malware.

A security engine may use event-stream processing and behavioral techniques to detect ransomware. The engine may detect process behavior associated with encrypting a file, encrypting a storage device, or disabling a backup file, and may assign a ransomware category to the process based thereon. The engine may initiate protection actions to protect system resources from the process, which may continue to execute. The engine may monitor the process for specific behavior corresponding to its ransomware category. Based on the extent to which such specific behavior is detected, the engine may determine that the process is not ransomware, assign a ransomware subcategory to the process, or adjust the process's threat score. Monitoring of the process may continue, and the threat score may be updated based on the process's behavior.

Rapid characterization of post-translationally modified proteins from tandem mass spectra
InactiveUS20070282537A1Low false positive rateHigh selectivityBiological testingSequence analysisFalse positive rateTandem mass spectrometry
A software algorithm that matches tandem mass spectra created simultaneously and automatically to theoretical peptide sequences derived from a protein database is disclosed. The program characterizes shotgun proteomic data sets obtained from proteins (such as histones) that possess extensive posttranslational modifications that are often difficult to characterize. Data is searched against all theoretical peptides including all combinations of modifications. The program returns four scores to assess the quality of match. The employed algorithm is sensitive to mass accuracy. For high mass accuracy data, a false positive rate as low as 2% may be achieved. Monte Carlo Simulations were also used to obtain a solution to statistical models and calculate statistical scores. The program can also be used to automatically and directly identify disulfide linked proteins and peptides in tandem mass spectra without chemical reduction and / or other derivatization using a probabilistic scoring model.

Non-intrusive method to identify presence of nuclear materials using energetic prompt neutrons from photon-induced fission
InactiveUS20090074128A1Improve detection rateSolve the high false positive rateConversion outside reactor/acceleratorsNeutron radiation measurementBeam energySmall fragment
Methods and systems for non-intrusively detecting the existence of fissile materials in a container via the measurement of energetic prompt neutrons are disclosed. The methods and systems use the unique nature of the prompt neutron energy spectrum from photo-fission arising from the emission of neutrons from almost fully accelerated fragments to unambiguously identify fissile material. The angular distribution of the prompt neutrons from photo-fission and the energy distribution correlated to neutron angle relative to the photon beam are used to distinguish odd-even from even-even nuclei undergoing photo-fission. The independence of the neutron yield curve (yield as a function of electron beam energy or photon energy) on neutron energy also is also used to distinguish photo-fission from other processes such as (γ, n). Different beam geometries are used to detect localized samples of fissile material and also fissile materials dispersed as small fragments or thin sheets over broad regions. These signals from photo-fission are unique and allow the detection of any material in the actinide region of the nuclear periodic table.

Systems and methods are described for synergistically combining static file based detection and behavioral analysis to improve both threat detection time and accuracy. An endpoint security solution running on an endpoint device generates a static analysis score by performing a static file analysis on files associated with a process initiated on the endpoint device. When the static analysis score meets or exceeds a static analysis threshold, then a network security platform treats the process as malicious and blocks execution of the process. When the static analysis score is less than the static analysis threshold, then the endpoint security solution obtains a dynamic analysis score for the process. The network security platform treats the process as malicious and causes execution of the process to be blocked based on a function of the static analysis score and the dynamic analysis score.
