#Ransomwhere alternative for windows portable
Meet the most comprehensive portable cybersecurity device JPCERT advises that attacks using this malware are ongoing. The C&C servers controlling infected systems are located in Lithuania, The Netherlands, Sweden, Hong Kong, and China. WellMess has been found in (unnamed by the report) Japanese companies, though it is unclear if the attacks are targeted exclusively in Japan, or if groups or individuals outside Japan have been affected. JPCERT has created a tool ( available here) to decrypt the content of those cookies, to identify what is being transmitted to the C&C server. The commands are transferred to the infected device via RC6 encrypted HTTP POST requests, with the results of executed commands transmitted to the C&C server via cookies. The malware gives a remote attacker the ability to execute arbitrary commands as well as upload and download files, or run PowerShell scripts to automate tasks. SEE: Network security policy (Tech Pro Research)Īccording a report by JPCERT, the WellMess malware can operate on Windows via Portable Excutables and on Linux via ELF (Executable and Linkable Format). However, Google’s Golang–which supports cross compiling to run on multiple operating systems–is now being utilized by attackers to target Windows and Linux workstations. Likewise, with enterprises moving away from installing Java SE on workstations, the viability of that approach has dwindled. In the more narrow view of actual executables, Java-based malware such as McRAT has proliferated in the past, though as Java on the desktop is practically unheard of on consumer computers in 2018. The proliferation of web-based attacks–which are inherently cross-platform, as they depend on browsers more than the underlying OS the browser runs on–makes this argument rather toothless. For a variety of reasons, this is a misguided notion. One of the oft-repeated reasons for using alternative operating systems is the suggestion that alternatives to Windows are more secure because malware is not produced for these minority systems–in effect, an argument in favor of security by minority.
