NoCry: No More Secure Encryption Keys for Cryptographic Ransomware

Since the appearance of ransomware in the cyber crime scene, researchers and anti-malware companies have been offering solutions to mitigate the threat. Anti-malware solutions differ on the specific strategy they implement, and all have pros and cons. However, three requirements concern them all: their implementation must be secure, be effective, and be efficient. Recently, Genç et al. proposed to stop a specific class of ransomware, the cryptographically strong one, by blocking unauthorized calls to cryptographically secure pseudo-random number generators, which are required to build strong encryption keys. Here, in adherence to the requirements, we discuss an implementation of that solution that is more secure (with components that are not vulnerable to known attacks), more effective (with less false negatives in the class of ransomware addressed) and more efficient (with minimal false positive rate and negligible overhead) than the original, bringing its security and technological readiness to a higher level

No Random, No Ransom: A Key to Stop Cryptographic Ransomware

To be effective, ransomware has to implement strong encryption, and strong encryption in turn requires a good source of random numbers. Without access to true randomness, ransomware relies on the pseudo random number generators that modern Operating Systems make available to applications. With this insight, we propose a strategy to mitigate ransomware attacks that considers pseudo random number generator functions as critical resources, controls accesses on their APIs and stops unauthorized applications that call them. Our strategy, tested against 524 active real-world ransomware samples, stops 94% of them, including WannaCry, Locky, CryptoLocker and CryptoWall. Remarkably, it also nullifies NotPetya, the latest offspring of the family which so far has eluded all defenses

Survey and analysis of vegetation and hydrological change in English dune slack habitats

This report details work conducted under a Memorandum of Agreement (MoA) between Natural England and the Centre for Ecology and Hydrology and British Geological Survey, initiating a programme of linked vegetation and hydrological studies. As stated in the MoA, the overall aim of this collaboration is ‘To improve the conservation status of dune wetlands of European importance and the condition of the dune wetland features of sand dune SSSIs identified in Appendix 1, through a major improvement in understanding of dune ecohydrological functioning.’ In consultation with Natural England, nine sites were selected for survey of the dune wetland component in the summer of 2012, aiming to partially repeat the Sand Dune Survey of Great Britain (SDGB) in the late 1980s. The selected sites hold 77% of the English dune wetland resource. At each site, all dune wetlands were mapped, with the exception of the three sites on the Sefton Coast, where the majority of the core area was mapped but not satellite areas. For each site the geological setting, surface topography, surface water features, climatic setting and land cover were assessed and the most important hydrological processes identified
