Whack-A-Bash: New Vulnerabilities add to Patch Confusion

September 29, 2014 Paul Roberts

The good news about the rapid, industry response to the revelations about exploitable security holes in GNU Bash (Bourne Again Shell) (aka “Shellshock”) is that Linux users had a fix in hand almost as soon as they became aware of the problem those patches addressed. The bad news about the quick fixes for the two issues, CVE-2014-6271 and CVE-2014-7169, from the likes of Red Hat, Ubuntu, Debian and others is that – in being early- they fail to fix the problems we don’t yet know about. And that’s what we’re seeing in the wake of last week’s storm of patches: a steady drip-drip of disclosures that suggest that Bash may contain other problems worthy of new fixes. Within hours of the disclosure of the first holes, there were problems discovered by Red Hat Product Security researcher Todd Sabin, who found additional “off by one” errors in Bash that were assigned CVE-2014-7186 and CVE-2014-7187 and […]

Infographic: Possible Attacks on The Internet of Things

September 24, 2014 Paul Roberts

The folks over at Trend Micro have put together a nice infographic that reminds us that all those smart devices connected to the Internet communicate through some well worn channels, namely: standard communications protocols like Wi-Fi, Ethernet and Bluetooth that connect devices to each other and the global Internet, as well as HTTP that are used to transmit data to and from cloud based resources like management interfaces. Of course those standard protocols also leave IoT devices vulnerable to a wide range of commodity attacks: from brute force password cracking on web based management consoles to Man in the Middle attacks that can sniff out authentication credentials and hijack sessions. Trend’s infographic does a good job of depicting the various layers in the IoT stack and some of the likely attack vectors for each layer. It also gives advice on how to protect yourself (use encryption, patch software vulnerabilities, disable unused ports). Nothing ground breaking […]

Online Authentication Group FIDO Alliance Grabs A Big Bone: Alibaba

September 23, 2014 Paul Roberts

The FIDO Alliance, an up-and-coming industry consortium aimed at simplifying online identity and doing away with passwords added IPO darling Alibaba to its Board of Directors, according to a statement on Tuesday. The FIDO (or “Fast IDentity Online”) Alliance announced that Alibaba Group’s payments business, Alipay will be among the first to deploy FIDO technology for secure payments authentication. On September 17, the company announced that it will use Nok Nok Labs’ FIDO-compliant NNL™ S3 Authentication Suite to enable secure online payments via the Fingerprint Sensor (FPS) technology on the Samsung Galaxy S5. Alipay customers will be able to make payments and transfers using Alipay’s mobile application, Alipay Wallet by applying their fingerprint to the Galxy’s fingerprint sensor. “We look forward to participating on the FIDO Alliance board, and assuring that commerce and authentication are uniquely cooperative and seamlessly compatible,” said Ni Liang, Alibaba group, senior director, department of security, in a statement. Mobile payments […]

You’re Invited: A Conversation on Password Security and Targeted Attacks

September 23, 2014 Paul Roberts

A note to Security Ledger readers that I’ll be facilitating a really interesting conversation this afternoon on password (in)security and how weak user authentication can undermine even the best laid security plans. The SANS Webinar, Security for the People: End User Authentication Security on the Internet” kicks off at 3:00 PM Eastern today (12:00 PM Pacific). You can register to join us using this link. My guest is DUO Security researcher Mark Stanislav, a frequent Security Ledger contributor and one of the smartest guys out there when it comes to passwords, authentication and securing the Internet of Things. There’s plenty to talk about: weak authentication schemes are the root cause of any number of prominent breaches – from the recent attacks the Apple iCloud accounts of A-list celebrities, to the breach at retailer Target (reportedly the result of a phishing attack on an HVAC contractor that Target used.) Mark and I […]

Compromised Website Used In Attack On SoHo Routers

September 11, 2014 Paul Roberts

The folks over at the web security shop Sucuri have an interesting post today that warns of a web-based attack launched from the site of a popular Brazilian newspaper that is targeting home broadband routers. According to Sucuri, researchers investigating a breach at the web site politica . estadao . com . br uncovered evidence that the hackers were using iframe attacks to try to change the DNS configuration on the victim’s DSL router, first by trying a brute force attack on the router’s default credentials. According to Sucuri, the payload was trying to crack default accounts like admin, root, gvt and other common usernames and a variety of known-default router passwords. Small office and home office (or SoHo) broadband routers are an increasingly common target for cyber criminals because many (most?) are loosely managed and often deployed with default administrator credentials. [Read Security Ledger coverage of home router hacks here.] In March, the firm Team Cymru published a report describing a widespread compromise of […]
