New Fileless Ransomware with Code Injection Ability Detected in the Wild

New Fileless Ransomware with Code Injection Ability Detected in the Wild
Jun 16, 2017
It is no secret that hackers and cybercriminals are becoming dramatically more adept, innovative, and stealthy with each passing day. While new forms of cybercrime are on the rise, traditional activities seem to be shifting towards more clandestine techniques that come with limitless attack vectors with low detection rates. Security researchers have recently discovered a new fileless ransomware, dubbed " Sorebrect, " which injects malicious code into a legitimate system process (svchost.exe) on a targeted system and then self-destruct itself in order to evade detection. Unlike traditional ransomware, Sorebrect has been designed to target enterprise's servers and endpoint. The injected code then initiates the file encryption process on the local machine and connected network shares. This fileless ransomware first compromises administrator credentials by brute forcing or some other means and then uses Microsoft's Sysinternals PsExec command-line utility to encry

14-Year-Old Japanese Boy Arrested for Creating Ransomware

14-Year-Old Japanese Boy Arrested for Creating Ransomware
Jun 06, 2017
Japanese authorities have arrested a 14-year-old boy in Osaka, a prefecture and large port city, for allegedly creating and distributing a ransomware malware . This is the first such arrest in Japan which involves a Ransomware-related crime. Ransomware is a piece of malware that encrypts files on a victim's computer and makes them inaccessible until the victim pays a ransom, usually in Bitcoins, in order to get the decryption keys for the encrypted files. Ransomware has been around for a few years, but currently, it has become a major cyber threat for businesses and users across the world. Just last month, the WannaCry ransomware hit over 300,000 PCs within just 72 hours, wreaking havoc worldwide. The recent arrest came after the teenager, who is a third-year junior high school student, created a ransomware virus and uploaded its source code on the Internet, according to multiple Japanese media. The student, who admitted to the allegations, combined free encryption

WannaCry Coding Mistakes Can Help Files Recovery Even After Infection
Jun 02, 2017
Last month  WannaCry ransomware  hit more than 300,000 PCs across the world within just 72 hours by using its self-spreading capabilities to infect vulnerable Windows PCs, particularly those using vulnerable versions of the OS, within the same network. But that doesn't mean WannaCry was a high-quality piece of ransomware. Security researchers have recently discovered some programming errors in the code of the WannaCrypt ransomware worm that might allow victims to restore their locked files without paying for any decryption key. After deeply analysing the WannaCry code, security company at Kaspersky Lab found that the ransomware was full of mistakes that could allow some of its victims to restore their files with publicly available free recovery tools or even with simple commands. Anton Ivanov, senior malware analyst at Kaspersky Lab, along with colleagues Fedor Sinitsyn and Orkhan Mamedov, detailed three critical errors made by WannaCry developers that could allow sysadmi
