When decryption is performed, stream is the ciphertext stream (at this time, the ciphertext stream contains data); icryptotransform is the decryption tool created in step 1, including the decryption algorithm; cryptostreammode enumeration is read, this means that data in the ciphertext stream is read to the byte [] array, and then converted from byte [] to the plain text stream and plaint

At the same time, the use of rescue discs can clear ransomware so that they no longer generate value. However, this newly discovered malware is also an improvement in

Analysis of several security threats facing the medical industry in 2016 At the beginning of 2016, the medical industry suffered from many security incidents, for example, ransomware attacks at the Los Angeles Hospital, ransomware attacks at a German hospital, patient monitors and drug administration systems, and attacks at the Melbourne Hospital. In 2016, just two months later, there were so many major sec

Every day, we are pleasantly surprised. What surprises us is the constant new cognition, which makes us think for a short time that we seem to understand the world better. The tangle of doubt and surprise seems to be the best temptation for mankind, driving us to explore all the t

Threat focus: CRYPTOWALL4 Continuously updated malwareOriginal article: http://blog.talosintel.com/2015/12/cryptowall-4.html 0x00 Abstract In the past year, Talos has spent a lot of time studying the operating principles of ransomware, managing it with other malware, and its economic impact. This research is of great value for developing detection methods and cracking attacks by attackers. CrytoWall is a malware. In the past year, it was first upgr

The cows used to eat grass and melamine. But what we eat is gutter oil. Can it be discharged? Is 10 years too long for us? We cannot go to a restaurant or take meals to and from work every day. There are still a lot of problems that cannot lead to the increasing reserves of waste oil in our human body, and the increasing number of toxins. We cannot control how to control it, but how to reduce the toxins in our body is a crucial issue of our research. Gutter oil is the oil extracted from the l
