Recently, a new threat has been discovered that targets Linux users.<\/p>\n
It should be noted up front that \u201cSambaCry\u201d is not a variant strain of the aforementioned ransomware, but rather, a security flaw in Linux that mirrors the one Wannacry used to exploit Windows-based systems. The vulnerability, officially named CVE-2017-7494. was dubbed SambaCry because of those similarities.<\/p>\n
Normally, Linux users avoid the kinds of security issues that plague Windows-based machines, but this is a bit of a different case, and here\u2019s why:<\/p>\n
There\u2019s a Linux service called Samba Server Service which provides SMB\/CIFS capabilities in Linux and Unix-based systems. While it\u2019s true that Linux can use any number of file sharing protocols, Samba is often used in environments featuring a mix of Linux and Windows PCs, because Windows PCs have a hard time dealing with Network File System Shares coming from machines running other OS\u2019s.<\/p>\n
When a Linux server is running Samba, some folders (called CIFS Shares) will appear as a network folder to Windows users.<\/p>\n
The security flaw allowed a remote user to send executable code to the server hosting the share, including code which could encrypt a file system and hold it for ransom.<\/p>\n
As you might expect, the Linux crowd treated this as a top priority and has already moved to patch the flaw.<\/p>\n
The long and the short of it is simply that if you\u2019re running a Linux server and using Samba, you\u2019re probably vulnerable unless you\u2019ve downloaded and applied the latest security patch. If you haven\u2019t, you should do so immediately.<\/p>\n
While Linux users have been fortunate to have suffered relatively fewer critical security flaws, this is a painful reminder that as good as the OS is, it\u2019s not bullet proof.<\/p>\n","protected":false},"excerpt":{"rendered":"
