Abstract: Malicious redirects in a redirect chain as a result of loading a web address are detected and blocked. A suspicion score is determined for a subject redirection domain based at least in part on the subject redirection domain's web address, and a rate of occurrence of the subject redirection domain in redirect chains leading to a malicious landing domain is calculated. Loading the subject redirection domain is blocked if the suspicion score exceeds a suspicion threshold or the rate of occurrence of the subject redirection domain exceeds a rate of occurrence threshold.

Abstract: Redundancy in a malware signature list is reduced by processing a plurality of pairs of records in a known malware signature list, where each pair of records comprises a file identifier and an associated malware detection. At least one of the file identifiers and the associated malware detections are mapped to symbols representing the file identifiers and the associated malware detections, the symbols taking less memory than the file identifiers and the associated malware detections. The mapped symbols representing the file identifiers and the associated malware detections are processed to remove at least some malware detections that are not needed to provide a desired degree of representation of each file identifier in the processed known malware signature list, and a processed known malware signature list is stored.

Abstract: Systems and methods use negative feedback to create generic rules for a high dimensional sparse feature space. A system receives a set of fingerprints, where a fingerprint can be a set of features of a file. The fingerprints can be clustered according to similarity. For each cluster, a proto-rule is created that has a condition for each feature. The proto-rule is simplified using negative feedback to create a well-formed rule having a comparatively small subset of the conditions in the proto-rule that are useful in determining malware. The well-formed rule can be added to a set of rules used in a malware detection system.

Abstract: A method of generating a similarity hash for an executable includes extracting a plurality of characteristics for one or more classes in the executable, and transforming the plurality of characteristics into a set of one or more class fingerprint strings corresponding to the one or more classes. The set of class fingerprint strings is transformed into a hash string using minwise hashing, such that a difference between hash strings for different executables is representative of the degree of difference between the executables. The hash of a target executable is compared with hashes of known malicious executables to determine whether the target executable is likely malicious.

The transport chain comprises chain clips, each chain clip having an upper part and a lower part, wherein the upper part and/or the lower part may be moveable relative to each other to move the chain clips between an open position and a closed position.

A chain opening mechanism may be actively and operably changed between an opening state and a closing state in order to open and close at least one chain clip disposed on a planar oriented section of the transport chain and/or to maintain an already opened chain clip in an open state.

Abstract: A packaging machine comprising a machine frame and at least one workstation with a lifting gear for supporting and moving a lower tool part between an open and a closed position. The workstation may include an upper tool part to act in cooperation with the lower tool part during a working operation. The lower tool part may be engaged with or near in proximity to an upper tool part in the closed position, and will be spaced apart from the upper tool part in the open position. A tilting mechanism is provided for a tool changing operation to tilt the lower tool part into a tilted position when the lower tool part is in the open position. In one embodiment, the lower tool part is removed from the packaging machine on a rail system in the direction corresponding to the tilted position.

Abstract: An arrangement for the model-based calibration of a mechanism in a workspace with calibration objects that are either directed laser radiation patterns together with an associated laser radiation-pattern generator or radiation-pattern position sensors. Functional operation groups made up of at least one laser radiation pattern and at least one position sensor interact in such a way when a radiation pattern impinges on the sensor that measured sensor position information values are passed along to computing devices that determine the parameters of a mathematical mechanism model with the aid of these measured values. In the process, at least two different functional operation groups are used to calibrate the mechanism, and at least two calibration objects from different functional operation groups are rigidly connected to one another.
