Cyberattack

Understanding the Modern DDoS Threat

The breadth of cyber threats that an organization must engage with and combat seemingly change on a daily basis. Each new technology, vulnerability or exploit vector results in a new threat that must be protected against. Meanwhile some forms of attack never appear to age -- they remain a threat to business continuity despite years of advances in defensive strategy. One particularly insidious and never-ending threat is that of the Distributed Denial of Service (DDoS) attack. more

Responsibilities of the DNS: “Oh YES you will!”, “Oh NO you will not!”

What is the responsibility of the DNS? Should the DNS be responsible for policing traffic across its infrastructure? Should the blocking and blacklisting of names or throttling of query packets be the responsibility of the DNS? From experience I know my opening paragraph has started passionate debates in more than one section of this globe. We at CommunityDNS have found ourselves right in the middle of such heated debates. "Oh YES you will!", "Oh NO you will not!" more

Escalating US, Chinese Silent War on the Internet

Jason Mick reporting in DailyTech: "In the definitive cyberpunk novel Neuromancer, published in 1984, author William Gibson prophetically envisioned that wars of the future would be fought over the internet -- a new construct at the time. Today that prediction appears on the verge of coming true as we stand on the threshold of a vast digital battle. Agents in China, believed to be working for, or endorsed by the Chinese federal government are carrying out a secret cyberwar against the U.S. government and U.S. businesses. And that war appears to be escalating." more

Two Years Later the Conficker Worm Not Entirely Disappeared

In a SecurityWeek article today, Ram Mohan writes: "Just over two years ago, the Internet held its breath. The high-profile, widely proliferated Conficker worm had been in the wild from October 2008; its largest mutation was revealed in February 2009, with a widely publicized activation date of April 1, 2009. ... What we do know: Conficker could have proved much more damaging than it ultimately did, and the threat has not entirely disappeared." more

More Targeted Phishing, Spam and Mobile Attacks; IBM Reports 150K Security Events Per Second

IBM today released the results from its annual X-Force 2010 Trend and Risk Report, identifying more targeted phishing, spam and mobile attacks. The report also finds cloud security continuing to evolve. "From Stuxnet to Zeus Botnets to mobile exploits, a widening variety of attack methodologies is popping up each day," says Tom Cross, threat intelligence manager, IBM X-Force. "The numerous, high profile targeted attacks in 2010 shed light on a crop of highly sophisticated cyber criminals, who may be well-funded and operating with knowledge of security vulnerabilities that no one else has. Staying ahead of these growing threats and designing software and services that are secure from the start has never been more critical." more

New Anti-phishing Initiative Introduced by Yahoo!

Neil Schwartzman writes to report: "The company announced the Yahoo! Mail Anti-Phishing Platform (YMAP) yesterday. The technology is predicated upon the use of both DKIM and Sender Policy Framework (SPF) to identify authentic messages. As part of the initiative, Yahoo! has partnered with email authenticators Authentication Metrics, eCert, Return Path, and Truedomain to provide broad-band coverage of well-known brands." more

Microsoft, Federal Agencies Take Down Rustock Botnet

Neil Schwartzman writes: "There is a lot of press on the profound effect the take-down of the Rustock botnet, affected by Microsoft, some U.S. federal agencies, and countless others working in the background to assist in the effort. CAUCE has aggregated a few of the best stories and data-points. A community congratulations, and thank-you to all those involved!" more

The report specifically discusses several items including: Registrars with current legal issues; Illicit Use of Privacy-Proxy WHOIS Registration; A study on the contracted obligation for Bulk WHOIS Access; and more. more

Cybercriminals Shifting Focus From Windows PCs to Other Systems and Mobile

In a major cybercrime turning point, scammers have begun shifting their focus away from Windows-based PCs to other operating systems and platforms, including smart phones, tablet computers, and mobile platforms in general, according to the Cisco® 2010 Annual Security Report, released today. The report also finds that 2010 was the first year in the history of the Internet that spam volume decreased, that cybercriminals are investing heavily in "money muling," and that users continue to fall prey to myriad forms of trust exploitation. more

WikiLeaks and Stuxnet - Smart Grid Wakeup Calls

The past couple of weeks have been pretty seminal for anyone concerned about the state of Internet security and the bigger picture as to how much we could - do - and should - trust the Web. These two strange words - WikiLeaks and Stuxnet - have suddenly entered our lexicon and there is a lot to be concerned about in the world of smart grid. more

Outlawing Botnets

The European Commission is apparently considering the promulgation and adoption of a directive that would, at least in part, criminalize botnets. As I understand it, the premise behind adopting such a directive is that since botnets are capable of inflicting "harm" on a large scale, we need to separately criminalize them. I decided to examine the need for and utility of such legislation in this post. more

Average Daily Malware at All Time High, Spam Lowest Since 2008

McAfee, Inc. today unveiled its McAfee Threats Report: Third Quarter 2010, which uncovered that average daily malware growth has reached its highest levels, with an average of 60,000 new pieces of malware identified per day, almost quadrupling since 2007. At the same time, spam levels decreased in volume this quarter, both globally and in local geographies. Spam hit a two year low this quarter while malware continued to soar. More than 14 million unique pieces of malware were identified in 2010, one million more than Q3 2009. more

“Capacity” - The Hidden Word?

What is so secret about the word, "Capacity"? As I read and talk with people I realize the word, "capacity" is typically missing from the DNS discussion. "Capacity" and "Security" are the two cornerstones to maximizing DNS resilience; both of which are typically missing from the DNS discussion. Have you seen a single DNS node easily process over 863,000 queries per second? Have you seen a network routinely handle over 50Gbits/second in outbound traffic alone without breaking a sweat? more

Myanmar Internet Down from Massive DDoS Attack

Craig Labovitz of Arbor Networks reports: "Back in 2007, the Myanmar government reportedly severed all Myanmar Internet connectivity in a crackdown over growing political unrest. Yesterday, Myanmar once again fell of the Internet. Over the course of the past several days, Myanmar's main Internet provider, the Ministry of Post and Telecommunication (or PTT for short), suffered a large, sustained DDoS attack disrupting most network traffic in and out of the country." more
