DDoS Attacks on US Banks This Week Peaked at 60 Gbps

Distributed denial-of-service (DDoS) attacks that targeted U.S. financial institutions this week have reached 60 Gbps, according to researchers from DDoS mitigation provider Arbor Networks. more

Hiding in Plain Sight: Post-Breach

The majority of network breaches begin and end with the installation of malware upon a vulnerable device. For the rest, once that initial malware beachhead has been achieved, the story is only just beginning. The breach disclosures that make the news are often confusing as they're frequently compiled from third-hand reports, opinions and technical assumptions. More often than not, they include a discussion about the malware - how advanced it was, etc. - and whether any 0-day vulnerabilities were likely used by the mysterious attacker. more

Closing in on the Google Hackers

Joseph Menn has an article on CNN.com wherein the crux of the story is that US experts are closing in on the hackers that broke into Google last month. It is believed by some that the Chinese government sponsored these hackers. China, naturally, denied involvement. My own take is that tools today are sophisticated enough such that you don't necessarily need state sponsorship in order to launch a cyber attack. more

Phishers Expand Number of Top Level Domains Abused, Policy Changes Found Effective in Prevention

The new Global Phishing Survey released by the Anti-Phishing Working Group (APWG) this month reveals that phishing gangs are concentrating their efforts within specific top level domains (TLDs), but also that anti-phishing policies and mitigation programs by domain name registrars and registries can have a significant and positive effect. The number of TLDs abused by phishers for their attacks expanded 7 percent from 145 in H2/2007 to 155 in H1/2008. The proportion of Internet-protocol (IP) number-based phishing sites decreased 35 percent in that same period, declining from 18 percent in the second half of 2007 to 13 percent in the first half of 2008. more

The Multinational Nature of Spam

I received a spam message the other day that went to my Junk Mail Folder. I decided to take a look at it and dissect it piece by piece. It really is amazing to see how spam crosses so many international borders and exploits so many different machines. Spammers have their own globally redundant infrastructure and it highlights the difficulties people have in combating the problem of it. more

Are You Getting Your News From Spam? My Mother Does

This is a story about my mother and Obama. My mother: "Have you heard about Obama? Really impressive guy." Me: "What about him?" My mother: "x, y and z." Me: "Where did you hear about this?" My mother: "I read email too, you are not the only one who is into technology." Luckily, my mother bases her opinion on more than just spam messages... more

Bruce Schneier: Government and Industry Have Betrayed the Internet, and Us

Bruce Schneier in an op-ed piece published in the Guardian on Thursday writes: "Government and industry have betrayed the internet, and us. By subverting the internet at every level to make it a vast, multi-layered and robust surveillance platform, the NSA has undermined a fundamental social contract..." more

Meltdown and Spectre: Security is a Systems Property

I don't (and probably won't) have anything substantive to say about the technical details of the just-announced Meltdown and Spectre attacks. What I do want to stress is that these show, yet again, that security is a systems property: being secure requires that every component, including ones you've never heard of, be secure. These attacks depend on hardware features... and no, many computer programmers don't know what those are, either. more

Tough Economy Requires Knowledge and Vigilance Online

If current predictions are correct, 2009 will be a tougher year than 2008 in terms of the economy. In tough economic times such as these it becomes increasingly important for us to follow recommended safety practices when going online. As the numbers of Internet-related fraud and financial scams continue to increase we should expect the current economic situation to produce more victims of cybercrime. Knowledge and vigilance are the keys to remaining safe while online. more

Exploits, Curdled Milk and Nukes (Oh my!)

Throughout the second half of 2012 many security folks have been asking "how much is a zero-day vulnerability worth?" and it's often been hard to believe the numbers that have been (and continue to be) thrown around. For the sake of clarity though, I do believe that it's the wrong question... the correct question should be "how much do people pay for working exploits against zero-day vulnerabilities?" more

DoT and DoH Guidance: Provisioning Resolvers

As part of a larger effort to make the internet more private, the IETF defined two protocols to encrypt DNS queries between clients (stub resolvers) and resolvers: DNS over TLS in RFC 7858 (DoT) and DNS over HTTPS in RFC 8484 (DoH). As with all new internet protocols, DoT and DoH will continue to evolve as deployment experience is gained, and they're applied to more use cases. more

Project Honey Pot: 1 Billion Spammers Served

Coen Dijkgraaf writes: "Project Honey Pot is a community of tens of thousands of web and email administrators from more than 170 countries around the world who are working together to track online fraud and abuse. The Project has been online since 2004 and each day receives millions of email and comment spam messages which are catalogued and shared with law enforcement and security partners. On Wednesday, December 9, 2009 at 06:20 (GMT) Project Honey Pot received its billionth email spam message. For the full article and some intersting statistics about spamming, see 1 Billion Spammers Served." more

FCC Releases New U.S. Anti-Bot Code

The Online Trust Alliance (OTA) joined a unanimous vote at the Federal Communications Commission's (FCC) Communications Security, Reliability and Interoperability Council (CSRIC) meeting today, approving the voluntary U.S. Anti-Bot Code of Conduct for Internet Service Providers (ISPs), also known as the ABCs for ISPs. As a member of the CSRIC appointed by FCC Chairman Julius Genachowski, the OTA has been working with the FCC and leading ISPs to develop this voluntary Code. more

USA Today: Spam Is Bad

A reasonably well informed article in Thursday's USA Today reminds us that in 2004 Bill Gates said the spam problem would be solved in early 2006, but here at the end of 2007 there's more spam than ever. They go through a laundry list of problems of spambots, new kinds of PDF and MP3 spam, and phishing, and a list of of partial or non-solutions including filters, walled gardens, and an odd system called Boxbe, a hybrid of whitelists, challenge/response, and pay for delivery. Oh, and Bill says he never said spam would be solved... more
