Canada Launching DNSSEC Test-Bed for Country’s .CA Domain

The Canadian Internet Registration Authority (CIRA) for the .ca country code Top-Level Domain yesterday announced the launch of a test-bed initiative for DNSSEC. CIRA’s Chief Information Officer, Norm Ritchie who made the official announcement at the SecTor security conference in Toronto, says it began the process of implementing DNSSEC in early 2009 and the implementation date is set for 2010. So far, over 15 Top-Level Domains have already deployed DNSSEC including dot-gov and dot-org.

DHS Asks Citizens to Practice Good “Cyber Hygiene”

Kicking off the sixth annual National Cybersecurity Awareness Month this October, the Department of Homeland Security (DHS) has urged computer users to practice good "cyber hygiene". The campaign was given a boost Wednesday when the Senate passed resolution 285 to support its goal to make U.S. citizens more aware of how to secure the internet. DHS has also announced that is has been given new authority to recruit and hire up to 1,000 cybersecurity professionals across the department to fill roles such as: cyber risk and strategic analysis; cyber incident response; vulnerability detection and assessment; intelligence and investigation; and network and systems engineering.

APWG: The Internet Has Never Been More Dangerous

Anti-Phishing Working Group (APWG) released its latest Phishing Activity Trends Report today warning that the number of unique phishing websites detected in June rose to 49,084, the highest since April, 2007's record of 55,643, and the second-highest recorded since APWG began reporting this measurement. "The number of hijacked brands ascended to an all-time high of 310 in March and remained, in historical context, at an elevated level to the close of the half in June," says the report.

Google Exec: ISPs Must Get Tough on Malware Infested Computers on Their Networks

Ryan Naraine reporting at Threatpost: "Head of Google's anti-malvertising team Eric Davis wants Internet Service Providers (ISPs) to look beyond profits and take a more proactive approach to dealing with malware-infested computers on their networks. During a keynote presentation at the Virus Bulletin conference here, Davis said competitors in the ISP space must look beyond profits and partner on new initiatives to deal with the "parasites" that have taken control of the Internet landscape."

Root Scaling Study Report is Out

Earlier this year, ICANN began to seriously consider the various effects of adding DNS protocol features and new entries into the Root Zone. With the NTIA announcement that the Root Zone would be signed this year, a root scaling study team was formed to assess the scalability of the processes used to create and publish the Root Zone. Properly considered, this study should have lasted longer than the 120 days -- but the results suggest that scaling up the root zone is not without risk -- and these risks should be considered before "green-lighting" any significant changes to the root zone or its processes. I, for one, would be interested in any comments, observations, etc. (The caveats: This was, by most measures, a rush job. My spin: This is or should be a risk assessment tool.) Full report available here [PDF].

Latest Study Suggests Computers Remain Infected Far Longer Than Previously Suggested

Contrary to previous security reports suggesting compromised machines remain infected for 6 weeks, experts at Trend Micro say these estimates are far from accurate. In its recent blog post the company said: "During the analysis of approximately 100 million compromised IP addresses, we identified that half of all IP addresses were infected for at least 300 days. That percentage rises to eighty percent if the minimum time is reduced to a month." Additionally the study also indicates that while three quarter of the IP addresses were linked to consumer users, the remaining quarter belonged to enterprise users.

Phishing Attack Attempts to Steal Consumer Data via Bogus Live-Chat Support

Security experts at RSA Research Lab have reported the discovery of a new type of phishing attack targeted against online banking customers that combines a typical phishing website with a live change session initiated by fraudsters. The technique dubbed "Chat-in-the-Middle" not only attempts to trick customers into entering their usernames and passwords into a phishing site but obtains further sensitive information (such as answers to secret questions used by banks to authenticate customers). According to the report, this attack is currently targeting a single U.S.-based financial institution, however operators of all online banking websites are cautioned.

Major Organizations Overlooking High Priority Security Risks, Too Much Focus on OS

According to a new security report released today by SANS Institute, TippingPoint and Qualys, the number of vulnerabilities found in applications in the last few years is far greater than the number of vulnerabilities discovered in operating systems. "On average, major organizations take at least twice as long to patch client-side vulnerabilities as they take to patch operating system vulnerabilities. In other words the highest priority risk is getting less attention than the lower priority risk."

Latvian ISP Closure Dents Cutwail Botnet ...for a Whole 48 Hours

From MessageLabs' latest report: "Real Host, an ISP based in Riga, Latvia was alleged to be linked to command-and-control servers for infected botnet computers, as well as being linked to malicious websites, phishing websites and 'rogue' anti-virus products. Real Host was disconnected by its upstream providers on 1 August 2009. The impact was immediately felt, where spam volumes dropped briefly by as much as 38% in the subsequent 48-hour period. Much of this spam was linked to the Cutwail botnet, currently one of the largest botnets and responsible for approximately 15-20% of all spam. Its activity levels fell by as much as 90% when Real Host was taken offline, but quickly recovered in a matter of days."

Apparently Legitimate Estonian ISP Operating as Large Cybercrime Hub Since 2005

An apparently legitimate ISP in Tartu, Estonian is reported to have been serving as the operational headquarters of a large cybercrime network since 2005 according to TrendWatch, the security research arm of TrendMicro. "An Estonian company is actively administering a huge number of servers in numerous datacenters, which together form a network to commit cybercrime. It appears that the company from Tartu, Estonia controls everything from trying to lure Internet users to installing DNS changer Trojans by promising them special video content, and finally to exploiting victims' machines for fraud with the help of ads and fake virus infection warnings..."

One Third of Companies Employing Staff to Monitor Content of Outbound Email, According to Survey

A recent survey of US companies conducted by Proofpoint has found companies increasingly concerned over data leaks via emplyee misuse of email, blogs, social networks, multimedia channels and text messages. From the report: "[A]s more US companies reported their business was impacted by the exposure of sensitive or embarrassing information (34 percent, up from 23 percent in 2008), an increasing number say they employ staff to read or otherwise analyze the contents of outbound email (38 percent, up from 29 percent in 2008). The pain of data leakage has become so acute in 2009 that more US companies report they employ staff whose primary or exclusive job is to monitor the content of outbound email (33 percent, up from 15 percent in 2008)."

Afilias and Neustar to Collaborate With ISC on DNS Security Initiative

Internet Systems Consortium (ISC) has announced that it is working with Afilias and Neustar, Inc. in the effort to support ISC's DNSSEC Look-aside Validation (DLV) registry by providing secondary DNS service for the DLV zone. DLV is a mechanism that provides many of the benefits of DNSSEC (short for DNS Security Extensions), enabling domain holders to secure their domain information today in advance of broader DNSSEC deployment and adoption. "Adding Afilias and Neustar as secondary DNS providers for the DLV zone demonstrates our collective understanding that DLV is a vitally important production service bigger than any single provider in the same way that there are 13 root server operators, not just one."

Dozens of US House of Representatives Websites Hacked

US House officials have confirmed hackers breaching several websites belonging to House of Representatives members in the past week. Portions of the websites were replaced by digital graffiti which began earlier this month, according to zone-h. Brian Krebs of the Washington Post reports: "Rep. Spencer Bachus has sent a letter to the House's chief administrative officer, requesting more information about the attacks. Bachus cites information provided to him by Gary Warner, director of research in computer forensics at the University of Alabama at Birmingham. Warner suggested that the break-ins at the House sites were caused not by password guessing [as reported initially], but by 'SQL injection,' an attack that exploits security weaknesses in Web server configurations."

Twitter Taken Down by DDoS Attack, Company Confirms

The Twitter micro-blogging service was knocked offline this morning for several hours as a result of a denial of service attack (DDoS). Twitter has confirmed and reported the attack in a post on its official blog earlier today: "We are defending against this [DDos] attack now and will continue to update our status blog as we continue to defend and later investigate." The company later reported that the service as been resumed but they are still continuing to defend against and recover from this attack. No further updates have been provided yet.

MAAWG Issues ISP Guidelines for End-User Bot Removal

Messaging Anti-Abuse Working Group (MAAWG) has issued the first best practices aimed at helping the global ISP industry work more closely with consumers to recognize and remove bot infections on end-users' machines. The paper outlines a three-step approach with recommendations for detecting bots, notifying users that their computers have been compromised, and guiding them in removing the malware.
