Linux IoT Worm Still Alive And Mining Virtual Coins

A few months ago we wrote about a new Internet worm notable because it spread between devices running the Linux operating systems, and because it had the ability to infect a range of non-PC devices including set top boxes. Symantec was quick to suggest that the worm, Linux.Darlloz, was the first “Internet of Things” malware. Now, three months later, Symantec is updating the story: noting that Darlloz is still out there, and seems to have  been put to use mining for virtual currencies. Writing on Symantec’s blog on Thursday, analyst Karou Hayashi said that researchers there discovered a new variant of Darlloz in January that included code changes and improvements from the version discovered at the end of 2013. Darlloz is versatile: it can run on devices using a variety of architectures, including the common Intel x86, but also hardware running the ARM, MIPS and PowerPC architectures. Those are more common […]

SOHOwned: 300K Home Routers Hacked

A string of reports in recent weeks has focused a spotlight on rising attacks against an often-overlooked piece of equipment that can be found in almost every home and business: the wireless router. Just this week, the security firm Team Cymru published a report (PDF) describing what it claims is a widespread compromise of small office and home office (SOHO) wireless routers that was linked to cyber criminal campaigns targeting online banking customers. Cymru claims to have identified over 300,000 SOHO devices (mostly in Asia and Europe) that were compromised. According to the report, the compromises first came to light in January, after Team Cymru analysts noticed a pattern of SOHO routers with overwritten DNS settings in central Europe. The affected devices are from a range of manufacturers, including well-known brands like D-Link, Micronet, Tenda and TP-Link. The devices were vulnerable to a number of attacks, including authentication bypass and cross-site […]
