Malware Attack Infected 25,000 Linux/UNIX Servers 220

wiredmikey writes "Security researchers from ESET have uncovered a widespread attack campaign that has infected more than 25,000 Linux and UNIX servers around the world. The servers are being hijacked by a backdoor Trojan as part of a campaign the researchers are calling 'Operation Windigo.' Once infected, victimized systems are leveraged to steal credentials, redirected web traffic to malicious sites and send as many as 35 million spam messages a day. 'Windigo has been gathering strength, largely unnoticed by the security community, for more than two and a half years and currently has 10,000 servers under its control,' said Pierre-Marc Bureau, security intelligence program manager at ESET, in a statement.

There are many misconceptions around Linux security, and attacks are not something only Windows users need to worry about. The main threats facing Linux systems aren't zero-day vulnerabilities or malware, but things such as Trojanized applications, PHP backdoors, and malicious login attempts over SSH. ESET recommends webmasters and system administrators check their systems to see if they are compromised, and has published a detailed report presenting the findings and instructions on how to remove the malicious code if it is present."

A Call For Rollbacks To Previous Versions of Software 199

colinneagle writes "In a blog post, Andy Patrizio laments the trend — made more common in the mobile world — of companies pushing software updates ahead without the ability to roll back to previous versions in the event that the user simply doesn't like it. iOS 7.1, for example, has reportedly been killing some users' battery power, and users of the iTunes library app TuneUp will remember how the much-maligned version 3.0 effectively killed the company behind it (new owners have since taken over TuneUp and plans to bring back the older version).

The ability to undo a problematic install should be mandatory, but in too many instances it is not. That's because software developers are always operating under the assumption that the latest version is the greatest version, when it may not be. This is especially true in the smartphone and tablet world. There is no rollback to be had for anything in the iOS and Android worlds. Until the day comes when software developers start releasing perfectly functioning, error-free code, we need the ability to go backwards with all software."

Camera Module Problems May Delay Samsung's Galaxy S5 70

concertina226 writes "There's less than a month to go before Samsung launches its new flagship Galaxy S5 smartphone worldwide on 11 April, and the new device has still not gone into mass production due to camera module manufacturing problems. The 16 megapixel camera module consists of six plastic pieces, one more piece than in the existing 13 megapixel camera modules in the Galaxy S4. The problem that Samsung is having is that even though the number of plastic pieces has gone up, the thickness of each piece has remained the same, so in order to fit the new camera module into the Galaxy S5, the lens makers will likely have to develop new technology to make thinner lenses. Not only that, joining six pieces together instead of five for the 13 megapixel camera modules increases the risk of optical faults surfacing at the lens manufacturers' plants dramatically."

Is Analog the Fix For Cyber Terrorism? 245

chicksdaddy writes "The Security Ledger has picked up on an opinion piece by noted cyber terrorism and Stuxnet expert Ralph Langner (@langnergroup) who argues in a blog post that critical infrastructure owners should consider implementing what he calls 'analog hard stops' to cyber attacks. Langner cautions against the wholesale embrace of digital systems by stating the obvious: that 'every digital system has a vulnerability,' and that it's nearly impossible to rule out the possibility that potentially harmful vulnerabilities won't be discovered during the design and testing phase of a digital ICS product. ... For example, many nuclear power plants still rely on what is considered 'outdated' analog reactor protection systems. While that is a concern (maintaining those systems and finding engineers to operate them is increasingly difficult), the analog protection systems have one big advantage over their digital successors: they are immune against cyber attacks.

Rather than bowing to the inevitability of the digital revolution, the U.S. Government (and others) could offer support for (or at least openness to) analog components as a backstop to advanced cyber attacks could create the financial incentive for aging systems to be maintained and the engineering talent to run them to be nurtured, Langner suggests."
Or maybe you could isolate control systems from the Internet.
