In-brief: Unmanned aerial vehicles manufactured by the Chinese firm DJI will be blocked from flying over the U.S. Capitol according to a statement by the company. The move raises important questions about the role that connected device makers will play in determining how, when and where customers use their products.

Last week, home broadband router maker ASUS was the latest vendor to issue an emergency patch for a critical vulnerability in its products. This, after proof-of-concept exploit code was released for the so-called “Inforsvr” vulnerability that affects several ASUS home routers. That vulnerability -if left unpatched – would allow anyone with access to a home- or small business network that used an ASUS broadband router to, essentially, commandeer the device. The “infosvr” feature is typically used for device discovery by the ASUS Wireless Router Device Discovery Utility, but the service also allowed unauthenticated users to execute commands through it using the “root” permissions, according to researcher Friedrich Postelstorfer, who created a proof of concept exploit for the security hole and released it on January 4. The exploit code finally prompted a patch from ASUS on January 13. The company had spent months analyzing the issue and working on a fix. Patch aside, it has been a worrying month for the […]
On Friday, the firm Allegro Software of Boxborough, Massachusetts, released an odd-sounding statement encouraging all its customers to “maintain firmware for highest level of embedded device security.” Specifically, Allegro wanted to warn customers about the need to apply a software update to address two recently discovered vulnerabilities affecting its Rom Pager embedded web server: CVE-2014-9222 and CVE-2014-9223, collectively known as the “Misfortune Cookie” vulnerabilities. That patch in question was released almost ten years ago – in 2005. As reported widely last week, the vulnerabilities affecting the Rom Pager software can be found in some 12 million broadband routers by manufacturers including Linksys, D-Link, Huawei, TP-Link, ZTE and Edimax. In short: some of the most common sellers of broadband routers in the world. The security firm CheckPoint discovered the vulnerabilities and issued a report about them. (The report web site is here and a PDF format report is here.) According to CheckPoint, the Misfortune Cookie vulnerability has to […]
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 […]
Computerworld UK has an interesting story that digs into a massive, 300 Gbps DDoS attack that used a flaw in the IPMI protocol to compromise 100,000 unpatched servers, which were then used to send junk traffic to the victim site. The attack was documented by the security firm VeriSign in its quarterly threat report. The flaw, in the Intelligent Platform Management Interface (IPMI) is a well-documented security hole that affects a wide range of devices. The attack in question took place in June and targeted what Verisign described as a content delivery network (CDN) in the media and entertainment sector. The attack combined a variety of techniques, including SYN, TCP and UDP protocols to flood a target data center. The attacks reached a peak traffic volume 300 Gbps and lasted more than a day, prompting Verisign to balance the load across its global network. Verisign attributed the massive volume of the attack to a botnet made up […]
