Podcast: Switch To IPV6 Demands A Security Re-Think

Editor’s Note: This  interview with Qualys CTO Wolfgang Kandek was originally recorded on March 29th. You’re probably not aware of it, but a major transformation is taking place on the Internet. We’ve exhausted the approximately 4.3 billion available addresses for IPV4 – Internet Protocol Version 4 – the Internet’s lingua franca. (Roughly 98% of all Internet traffic.)   With billions of new, intelligent devices set to join the global Internet in the next decade, a new addressing scheme was needed. Enter Internet Protocol Version 6 (IPV6), which will create a practically inexhaustible supply of new addresses and some much needed, new security features that can prevent man in the middle attacks, ARP poisoning and a host of other ills. But organizations that have the luxury of waiting to upgrade their networks should do so, says Qualys CTO Wolfgang Kandek in this exclusive interview with The Security Ledger. From vulnerability scanning to […]

DPRKurious: Is North Korea Really Behind Cyber Attacks On The South?

The news keeps coming out of South Korea, where a mysterious rash of hacks and virus infections early Thursday compromised tens of thousands of machines running at banks, broadcasters and other firms, erasing data and causing widespread disruption. Here’s the latest: South Korean Officials “Strongly Suspect” North Korea South Korean government officials made their most direct statements to date (albeit anonymously) on the possible source of the attack, saying that they had a “strong suspicion” that the government of the Democratic People’s Republic of Korea (DPRK) was responsible. Speaking to the YonHap News Agency, the official, identified as a “high ranking official in the office of President Cheong Wa Dae,” refused to elaborate. However, he may have been referring to the preliminary results of the Korea Communications Commission (KCC) which traced the malicious code responsible for crippling computers at broadcasters and banks to an IP address in China. South Korean […]

Botnet Of Embedded Devices Used To Map Internet

Botnets are mostly linked with spam e-mail campaigns, denial of service attacks and data theft. But global networks of compromised hosts can be used for a variety of ends – not all of them malicious. That was the idea behind “Internet Census 2012,” a stealth project by an unnamed and unknown researcher/hacker to map the entire IPV4 Internet address space using a massive network of compromised devices. The results, published in the form of a research paper, underscore the problem of  unsecured embedded devices, including set top boxes, home routers and critical infrastructure, with the hacker able to locate and compromise these systems, creating a botnet of more than 420,000 nodes. According to a copy of the report, the project grew out of an experiment to locate unprotected devices online using nmap, the open source scanning tool. By compromising each vulnerable host and then enlisting it to scan for other […]

ISP Telenor: Execs Laptops Emptied in Cyber Spy Operation

The Norwegian telecommunications firm Telenor told authorities in that country that a sophisticated cyber spying operation compromised the computers of leading executives and “emptied” them of sensitive information, including e-mail messages, computer files and passwords, according to a report Sunday by Aftenposten. Several executives of Telenor were the subjects of “extensive, organized industrial espionage,” the report said, quoting Telenor Norway’s director, Rune Dyrlie. The company has reported the incident to  Nasjonal sikkerhetsmyndighet – or NSM – Norway’s national security authority as well as Nor-CERT, Norway’s Computer Emergency Readiness Team and the cyber defense unit Cyberforsvaret. “We take it very seriously by several bosses in Telenor stolen sensitive information. It is quite clear that those behind, got downloaded stolen information. There is no doubt that we have lost data,” Dyrlie told Aftenposten. Dyrlie said that the company missed the initial infection, which used “new, customized software.” The first indication of a compromise came after automated monitoring software operated […]
