Three malicious npm JavaScript packages have been found opening shells on Linux and Windows systems. According to npm staff: "Any computer that has this package installed or running should be considered fully compromised." . Three JavaScript packages have been removed from the npm portal on Thursday for containing malicious code. According to advisories from the npm security team, the three JavaScript libraries opened shells on the computers of developers who imported the packages into their projects. The shells, a technical term used by cyber-security researchers, allowed threat actors to connect remotely to the infected computer and execute malicious operations. The npm security team said the shells could work on both Windows and *nix operating systems, such as Linux, FreeBSD, OpenBSD, and others. . On Thursday, a trio of JavaScript packages was taken down from the npm repository due to the discovery of harmful shell access vulnerabilities..

The flaw, known as the "shell" exploit, was publicized Wednesday on a security mailing list, along with a link to a fix for the problem. Updated versions of the affected software programs, which include the Mozilla, Firefox and Thunderbird browsers, have been released. Developers said the flaw affects only Windows users, not computers running the Macintosh and Linux operating systems. . . .. The flaw, known as the "shell" exploit, was publicized Wednesday on a security mailing list, along with a link to a fix for the problem. Updated versions of the affected software programs, which include the Mozilla, Firefox and Thunderbird browsers, have been released. Developers said the flaw affects only Windows users, not computers running the Macintosh and Linux operating systems. Like recent Internet Explorer vulnerabilities, this flaw only allows the attacker the ability to run an existing program and requires that security problems in other applications be exploited to gain further access. The flaw can be used to pass a file extension to the operating system. Windows XP will then run the helper application corresponding to that file extension. The main threat comes from the ability of an attacker to pass parameters to exploit vulnerabilities in a specific helper application, which could give an outsider access to the system. A shell problem could also cause the computer to freeze. . The vulnerability, referred to as the 'core' exploit, was disclosed Tuesday on a cybersecurity forum, accompanied by a solution..
