Did the DPRK Hack Sony?

My Twitter feed has exploded with lots of theorizing about whether or not North Korea really hacked Sony. Most commentators are saying "no", pointing to the rather flimsy public evidence. They may be right -- but they may not be. Worse yet, we may never know the truth. One thing is quite certain, though: the "leaks" to the press about the NSA having concluded it was North Korea were not unauthorized leaks; rather, they were an official statement released without a name attached. more

Preventing Future Attacks: Alternatives In DNS Security Management - Part I

The October 21 DDoS attacks against the 13 root-name servers containing the master domain list for the Internet's Domain Name System (DNS), (which reportedly took offline 9 of the 13 servers) remain a clear and daunting reminder of the vulnerabilities associated with online security. Many DNS authorities have named the most recent hit the largest DDoS attack against the root server system. Chris Morrow, network security engineer for UUNET, the service provider for two of the world's 13 root servers, recently told The Washington Post... more

Massachusetts School District Pays Hackers $10K in Bitcoin, Police Calls Case “Impossible” to Solve

A Massachusetts school district was forced to pay a $10,000 Bitcoin ransom to hackers following a cyberattack that blocked access to its system. more

Old Dog, New Tricks: Gift Card Scams in Social Networks

In the past few months, a flurry of gift card scams leveraging such high-profile brands as Best Buy, Whole Foods and IKEA have emerged on Facebook. These scams often use the brand's logo, website URL, or general "look and feel" on Facebook "fan" pages to give the impression that these offers are legitimate. Some scams are even bold enough to include bogus, non-interactive fan comments to add a greater sense of authenticity to the gift card offer. To date, these scams have been successful at tricking tens of thousands of consumers. In just one day, for example, a fan page titled "IKEA Get a FREE $1000 IKEA Gift Card! (ONLY AVAILABLE 1 DAY)" registered 40,000 fans before being shut down. more

Chinese Hackers and Cyber Realpolitik

For many people the comments made by Michael Hayden, Former Director of the Central Intelligence Agency, at this week's Black Hat Technical Security Conference in Abu Dhabi may have been unsettling as he commented upon the state of Chinese cyber espionage. I appreciate the candor of his observations and the distinction he made between state-level motivations. In particular, his comment... more

Mozilla Named “Internet Villain” for Supporting DNS-Over-HTTPS by a UK ISP Association

Mozilla was nominated as one of the three ISPAUK's 2019 Internet Villains for their proposed approach "to introduce DNS-over-HTTPS in such a way as to bypass UK filtering obligations and parental controls, undermining internet safety standards in the UK." more

Software Insecurity: The Problem with the White House Cybersecurity Proposals

The White House has announced a new proposal to fix cybersecurity. Unfortunately, the positive effects will be minor at best; the real issue is not addressed. This is a serious missed opportunity by the Obama adminstration; it will expend a lot of political capital, to no real effect... The proposals focus on two things: improvements to the Computer Fraud and Abuse Act and provisions intended to encourage information sharing. At most, these will help at the margins; they'll do little to fix the underlying problems. more

DNSSEC and DNS over TLS

The APNIC Blog has recently published a very interesting article by Willem Toorop of NLnet Labs on the relationship between Security Extensions for the DNS (DNSSEC) and DNS over Transport Layer Security. Willem is probably being deliberately provocative in claiming that "DoT could realistically become a viable replacement for DNSSEC." If provoking a reaction was indeed Willem's intention, then he has succeeded for me, as it has prompted this reaction. more

DNSSEC is But One Link in the Security Chain

As the implementation of DNSSEC continues to gather momentum and with a number of ccTLDs, and the '.org' gTLD having deployed it into their production systems, I think it is worth pausing to take a look at the entire DNSSEC situation. Whilst it is absolutely clear that DNSSEC is a significant step forward in terms of securing the DNS, it is but one link in the security chain and is therefore not, in itself, a comprehensive solution to fully securing the DNS system. more

97% of All Global 2000 Companies at Risk from SAD DNS Attack

There is a new threat in town known as "SAD DNS" that allows attackers to redirect traffic, putting companies at risk of phishing, data breach, reputation damage, and revenue loss. What is SAD DNS? No, it isn't the domain name system (DNS) feeling moody, but an acronym for a new-found threat -- "Side-channel AttackeD DNS" discovered by researchers that could revive DNS cache poisoning attacks. more

The Human Factor in DDoS Attacks

Ripped from the headlines: A recent DDoS attack lasted an entire 60 days. In other news, a single site was attacked 218 times in Q2 alone. To those of us in the business of protecting Web infrastructure, these stories are hardly surprising. What's notable, though, is where they were reported, in The Financial, whose focus is banking and financial services, not technology. The reporters used the term "DDoS" as if it were as common as "hedge fund," something everyday business people, not just techies, grasp. It's this human element that caught my interest and got me thinking a little. more

More Than 500 Schools in the U.S. Hit by Ransomware in 2019, Says Report

A recent report published by the cybersecurity firm Armor says ransomware infections have hit over 500 US schools in 2019 to date. Armor warns the rate of attack seems to be picking up with 15 new ransomware victims in the last two weeks, all of them educational institutions. more

Half of Phishing Sites in the Wild Have SSL Certificates and Show Padlock Security Icon, Study Finds

A new study by anti-phishing company PhishLabs reveals 49 percent of all phishing sites in the third quarter of 2018 had Secure Sockets Layer or SSL with HTTPS in their URL. more

Day 30: Kaminsky DNS Bug Disclosure

In a highly anticipated presentation, Internet security researcher Dan Kaminsky today gave details of the much talked about Domain Name System (DNS) vulnerability issue which has been intensely covered since it was publicly announced a month ago on Jul 8th. Although original plans entailed keeping the bug details undisclosed for 30 days in order to allow for necessary security patches to be implemented around the world, details of the bug were eventually leaked-and-confirmed 13 days after its public announcement. Even so, just hours ago in jam-packed ballroom during the Black Hat conference, Kaminsky delivered his 100-plus-slide presentation detailing the DNS flaw that, if exploited, could potentially "destroy the Web". more

Behind the Smoke Screen of Internet and International Infrastructure

In my recent write-up I start by discussing some recent threats network operators should be aware of, such as recursive DNS attacks. Then, a bit on the state of the Internet, cooperation across different fields and how these latest threats with DDoS also relate to worms and bots, as well as spam, phishing and the immense ROI organized crime sees. I try and bring some suggestions on what can be done better, and where we as a community, as well as specifically where us, the "secret hand-shake clubs" of Internet security fail and succeed. Over-secrecy, lack of cooperation, lack of public information, and not being secret enough about what really matters. more
