Linux.MulDrop.14 is a Linux worm that seeks out networked Raspberry Pi systems with default root passwords; after taking them over and ZMap and sshpass, it begins mining an unspecified cryptocurrency, creating riches for the malware's author and handing you the power-bill. <\/p>\n
Experts say the initial infection takes place when Raspberry Pi operators leave their devices' SSH ports open to external connections. <\/p>\n
Once a Raspberry Pi device is infected, the malware changes the password for the \"pi\" account to: <\/p>\n
$6$U1Nu9qCp$FhPuo8s5PsQlH6lwUdTwFcAUPNzmr0pWCdNJj.p6l4Mzi8S867YLmc7BspmEH95POvxPQ3PzP029yT1L3yi6K1 <\/p>\n
After this, Linux.MulDrop.14 shuts down several processes and installs libraries required for its operation, including ZMap and sshpass. <\/p>\n
The malware then launches its cryptocurrency mining process and uses ZMap to continuously scan the Internet for other devices with an open SSH port. <\/p>\n
Once it finds one, the malware uses sshpass to attempt to log in using the username \"pi\" and the password \"raspberry.\" Only this user\/password combo is used, meaning the malware only targets Raspberry Pi single-board computers. <\/p>\n

Pity poor Turla, the advanced persistent threat hacking group closely associated with the Russian government who were outed yesterday for their extremely clever gimmick of using Britney Spearss Instagram account as a covert channel for controlling compromised computers in the field while protecting their command and control servers; today, Turla faces another devastating disclosure, a [] <\/p>\n
The independent, Congressionally mandated Health Care Industry Cybersecurity Task Force released its report last week, setting out their findings about the state of security in Americas health technology (very, very, very bad) and their recommendations (basic commonsense cybersecurity 101). <\/p>\n
A key weakness in malicious software is the Command and Control (C&C) system: a central server that the malware-infected systems contact to receive updates and instructions, and to send stolen data. Anti-malware researchers like to reverse engineer malicious code, discover the C&C servers address, and then shut it down or blacklist it from corporate routers. <\/p>\n
