DNS Amplification Attacks: Out of Sight, Out of Mind? (Part 3)

Previous posts (Part 1 and Part 2) offer background on DNS amplification attacks being observed around the world. These attacks continue to evolve. Early attacks focused on authoritative servers using "ANY" queries for domains that were well known to offer good amplification. Response Rate Limiting (RRL) was developed to respond to these early attacks. RRL, as the name suggests, is deployed on authoritative servers to rate limit responses to target names. more

What Trademark Owners Need to Know to Avoid Reverse Domain Name Hijacking

A cybersecurity company recently attempted reverse domain name hijacking for an exact match domain name of its brand, and in so doing, failed in both its bid to take ownership of the domain and potentially damaged their reputation by using this somewhat nefarious tactic and abusing the Uniform Domain Name Dispute Resolution Policy (UDRP) process. more

Facebook, Privacy, and Cryptography

There has long been pressure from governments to provide back doors in encryption systems. Of course, if the endpoints are insecure it doesn't matter much if the transmission is encrypted; indeed, a few years ago, I and some colleagues even suggested lawful hacking as an alternative. Crucially, we said that this should be done by taking advantage of existing security holes rather than be creating new ones. more

Data Breaches Reported During 2016 Exposed Over 4.2 Billion Records

2016 broke the previous all-time high, set back in 2013, for the number of records exposed from reported data breaches. more

More on ‘Researchers Hijack Storm Worm to Track Profits’

Always good for information on the spam economy, Brian Krebs of the Washington Post has just published a truly fascinating article: Researchers Hijack Storm Worm to Track Profits. Bottom line: a one-in-twelve-million conversion rate of spam to sales seems to be enough to keep the spam economy going. The article covers a project by researchers at UC San Diego and UC Berkeley, who managed to infiltrate the Storm Worm bot network and take over a small portion of it. more

The Advanced Persistent Threats (APT) Deception

Most of the good thrillers I tend to watch have spies and assassins in them for some diabolical reason. In those movies you'll often find their target, the Archduke of Villainess, holed up in some remote local and the spy has to fake an identity in order to penetrate the layers of defense. Almost without exception the spy enters the country using a fake passport; relying upon a passport from any country other than their own... So, with that bit of non-fiction in mind, why do so many people automatically assume that cyber-attacks sourced from IP addresses within China are targeted, state-sponsored, attacks? more

On the Success of Malware

There's often a lot of discussion about whether a piece of malware is advanced or not. To a large extent these discussions can be categorized as academic nitpicking because, at the end of the day, the malware's sophistication only needs to be at the level for which it is required to perform -- no more, no less. Perhaps the "advanced" malware label should more precisely be reattributed as "feature rich" instead. more

The Recent DDoS Attacks on Banks: 7 Key Lessons

Starting in mid-September, one of the largest and most sophisticated DDoS attacks ever targeted the titans of American banking. Initially, victims included Bank of America, JPMorgan Chase, Wells Fargo, PNC Bank, and U.S. Bancorp. In the weeks to come, others would also feel the pain. Websites crashed, customers were unable to make transactions and IT professionals and PR gurus went into panic mode. Leon Panetta, U.S. Secretary of Defense, said the attacks foreshadowed a "Cyber Pearl Harbor." more

Y2038: It’s a Threat

Last month, for the 20th anniversary of Y2K, I was asked about my experiences. (Short answer: there really was a serious potential problem, but disaster was averted by a lot of hard work by a lot of unsung programmers.) I joked that, per this T-shirt I got from a friend, the real problem would be on January 19, 2038, and 03:14:08 GMT. Why might that date be such a problem? On Unix-derived systems, including Linux and MacOS, time is stored internally as the number of seconds since... more

Canada’s Electronic Spy Agency Makes Its Malware Analysis Tool Public

Canada's Communications Security Establishment (CSE) which rarely discloses detail of its activities has taken the "unprecedented step" of releasing one of its own cyber defense tools to the public, in a bid to help companies and organizations better defend their computers and networks against malicious threats. more

In Network Security Design, It’s About the Users

One of the longstanding goals of network security design is to be able to prove that a system -- any system -- is secure. Designers would like to be able to show that a system, properly implemented and operated, meets its objectives for confidentiality, integrity, availability and other attributes against the variety of threats the system may encounter. A half century into the computing revolution, this goal remains elusive. 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

A Cynic’s View of 2015 Security Predictions - Part 3

A number of security predictions have been doing the rounds over the last few weeks, so I decided to put pen to paper and write a list of my own. However, I have a quite a few predictions so I have listed them over several blog posts. After all, I didn't want to bombard you with too much information in one go! Part three examines the threats associated with data breaches. 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.

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.
