  • Publication number: 20210176233
    Abstract: An author of a malicious websites campaign (scam or phishing) likely uses a legitimate third-party service to facilitate the malicious campaign. An example includes legitimate CAPTCHA (Completely Automated Public Turing Test to Tell Computers and Humans Apart) services to conceal the malicious campaign from automated security scanners. A security service/platform can employ a detection pipeline that leverages use of CAPTCHA keys across websites of a malicious websites campaign. Websites that use CAPTCHA keys found in known malicious websites can at least be identified as suspect and communicated to firewalls.

  • Publication number: 20210120034
    Abstract: Web sites are crawled using multiple browser profiles to avoid malicious cloaking. Based on web page content returned from HTTP requests using the multiple browser profiles, web sites returning substantively different content to HTTP requests for different browser profiles are identified. Web sites are further filtered by common cloaking behavior, and redirect scripts are extracted from web page content that performed cloaking. Signatures comprising tokenized versions of the redirect scripts are generated and compared to a database of known cloaking signatures. URLs corresponding to signatures having approximate matches with signatures in the database are flagged for recrawling. Recrawled URLs are verified for malicious cloaking again using HTTP requests from multiple browser profiles.

  • Publication number: 20210075800
    Abstract: Presented herein are intrusion detection systems and algorithms for networked vehicle controllers and devices, methods for making/using such systems and algorithms, and motor vehicles with a network of ECUs and network-profiling intrusion detection capabilities. A method for detecting intrusions into an onboard network of vehicle controllers includes determining the current state of operation of a vehicle, and identifying a network traffic pattern table corresponding to the vehicle's current state of operation. Network traffic flow for one of the in-vehicle controllers is monitored when exchanging data over the Ethernet communication interface while the motor vehicle is operating in the current state of operation. The method then determines if a traffic characteristic of the monitored network traffic flow is outside a calibrated boundary that is determined from the network traffic pattern table.

  • Patent number: 10380008
    Abstract: A framework is described herein for identifying implicit assumptions associated with an SDK and its accompanying documentation (e.g., dev guide). An implicit assumption is information that is not expressly stated in the documentation, but which would be useful in assisting an application developer in building an application. The framework also describes a systematic approach for identifying one or more vulnerability patterns based on the identified implicit assumptions. An application developer may run a test on an application that is being developed to ensure that it does not have any deficiency which matches a vulnerability pattern.

  • Patent number: RE47975
    Abstract: An STTMRAM element includes a magnetic tunnel junction (MTJ) having a perpendicular magnetic orientation. The MTJ includes a barrier layer, a free layer formed on top of the barrier layer and having a magnetic orientation that is perpendicular and switchable relative to the magnetic orientation of the fixed layer. The magnetic orientation of the free layer switches when electrical current flows through the STTMRAM element. A switching-enhancing layer (SEL), separated from the free layer by a spacer layer, is formed on top of the free layer and has an in-plane magnetic orientation and generates magneto-static fields onto the free layer, causing the magnetic moments of the outer edges of the free layer to tilt with an in-plane component while minimally disturbing the magnetic moment at the center of the free layer to ease the switching of the free layer and to reduce the threshold voltage/current.
