Twitter, DDoS and the Motivations Behind the Attack

As we all know by now, last week, on Thursday, August 7, Twitter was hit with a denial-of-service attack that took it down for several hours. Other social networking sites like Facebook, LiveJournal, Youtube and Blogger were also hit. They managed to repel the attack although Facebook was not quite as successful as the other larger players. The theory floating about at the moment is that this was a politically oriented play designed to target one guy: a blogger. We are nearing the 1-year anniversary of a the Russian/Georgian 2008 war. There is a pro-Georgian blogger by the username of "Cyxymu" who had accounts on all of these services. more

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)." more

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." more

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." more

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. more

OpenDNSSEC Launched to Help Drive Adoption of DNSSEC

A team of developers including .SE (The Internet Infrastructure Foundation), LNetLabs, Nominet, Kirei, SURFnet, SIDN and John Dickinson have come together to create open source software, called OpenDNSSEC, to make it easier to deploy DNSSEC. Patrik Wallström, responsible for DNSSEC at .SE comments: "In order to spread the use of DNSSEC to an increased number of domain names, the management surrounding this technology must be simplified. Together with a number of collaborators, we're developing OpenDNSSEC. Leveraging our deployment experience, we will produce a well-packaged, easy-to-use and flexible DNSSEC tool that eliminates all manual procedures. Those in charge of name servers no longer need detailed knowledge about the protocol in order to use it." more

Survey Suggests Strained Budgets Causing Security Cutbacks on Known Threats

A recent survey of security professionals by RSA Conference with regards to critical security threats and infrastructure issues currently faced, revealed budgetary constrains as the top challenge currently faced. According to reports, the study suggests that even though practitioners are most concerned about email phishing and securing mobile devices, technologies addressing these needs are at risk of being cut from IT budgets. 72% percent of respondents indicated a rise in email-borne malware and phishing attempts since Fall 2008, with 57% stating they have seen an increase in Web-borne malware. Concerns about zero-day attacks and rogue employees as a result of layoffs were cited by 28% and 26% of survey respondents, respectively. more

Nuclear Command and Control Structures Vulnerable to Cyber Terrorism

A research paper commissioned by the International Commission on Nuclear Non-proliferation and Disarmament (ICNND) suggests that nuclear command and control systems are vulnerable to cyber terrorism. "Despite claims that nuclear launch orders can only come from the highest authorities, numerous examples point towards an ability to sidestep the chain of command and insert orders at lower levels," says the report. more

Malware Production Continues at Record-Setting Pace; 6000 Unique Pieces Per Day

Security researches report seeing as much unique malware in the first half of 2009 as seen in all of 2008. "This is quite something when you consider that in 2008 we saw the greatest ever growth in malware," says David Marcus of McAfee Avert Labs. More specifically, Marcus in a blog post writes that the numbers add up to an average of 200,000 unique pieces malware monthly or more than 6,000 a day. "Bear in mind these are malware we consider unique (something we had to write a driver for) and does not count all the other malware we detect generically or heuristically... When you add in the generic and heuristic detections the number becomes truly mind boggling," writes Marucs. more

More on Networks and Nationalization With Respect to Cyberwar

As a follow up to Susan Brenner's Networks and Nationalization and my comment there, I will go further in this post and talk about the "cyberwar" and "offense" aspects of her article. I think I made this point elsewhere as well... but before getting into a war, it'd be a brilliant idea to actually know that you can win. Cyberwarfare is the sort of game where you don't really need to be a huge government with the largest standing army in the world and sophisticated weaponry in order to win... more

When You Hear “Security,” Think “National Sovereignty”

These days you can hardly talk about Internet governance without hearing about security. DNSSEC is a hot issue, ICANN's new president is a cyber-security expert, and cyberattacks seem to be a daily occurrence.
This reflects a larger shift in US policy. Like the Bush administration before it, the Obama administration is making security a high priority for the US. Only now the emphasis is on security in cyberspace. The outlines of the new policy were published in the recent US Cyberspace Policy Review, which even recommends a cyber security office directly in the White House. more

Data Security: Being Open About Secrecy

It must be tricky to be an advocate of transparency when your job involves selling serious encryption tools to government departments, large and small companies, hospitals and people who are concerned about having their bank account details hijacked from a home PC. After all, the point about good encryption software and the systems that surround it is that they provide a way to keep your secrets secret, while open government and the effective regulation of financial services would seem to require the widest possible dissemination of all sorts of operational data... more

New CEO Stresses ICANN’s Role in Cybersecurity

One summer sport in Internet governance is speculating on what direction ICANN's new CEO will take it in. Making the media rounds yesterday on Fox and Lehrer News Hour to talk about the recent DDoS attacks on US and S. Korea government and commercial websites, new CEO Rod Beckstrom pushed how the response to cyber attacks is a coordinated effort, he also alluded to ICANN's role in similar attacks. Responding to a question on the News Hour about the USG policy response to dealing with cyber attacks, Beckstrom highlighted the critical role of ISP filtering, and identified the "organic" as well as "somewhat structured" coordination which occurs during a typical response. More interestingly, he plugged ICANN's facilitating role. more

Global Recession Appears to Have Also Hit the Malware Industry

According to reports by German software security company G Data, since the beginning of summer, the malware community appears to have been scaling back its activities. This considerable reduction is, according to the estimates of G Data security expert Ralf Benzmüller, not solely due to the forthcoming holiday season. The global recession appears to have also hit the eCrime economy. "This phenomenon emerges every year as something new. At the start of the holiday season, the number of malware programs falls. One reason for this is the worldwide onset of the travel season, which, based on experience, causes a drop in the number of active Internet users. However, this does not explain a collapse of more than 30 percent," says Ralf Benzmüller. more

Trojans Fastest Growing Category of Data-Stealing Malware

The Anti-Phishing Working Group (APWG) recently reported that the number of sites infecting PCs with password-stealing crimeware reached an all time high of 31,173 in December 2008 - an 827 percent increase from January. And according to a report just released by Trend Micro's Focus Report, 93 percent of data-stealing malware have been identified as Trojans in the first quarter of 2009. more
