As recently reported, spam volumes indicate spam has nearly jumped back up to its pre-McColo shutdown levels. However, Symantec's The State of Spam report has also observed that in recent days spammers are increasingly piggybacking on legitimate newsletters and using the reputation of major social networking sites to try and deliver spam messages into recipients' inboxes... In its special URL investigation the report also indicates that on average approximately 90 percent of all spam messages today contain some kind of a URL. Additionally, analysis of data from past recent days, according to Symantec, have shown that 68% of all URLs in spam messages had a '.com' Top-Level Domain (TLD), 18% had a China's '.cn' ccTLD and 5% had a '.net'. more
In February 2012, Neustar surveyed IT professionals across North America to better understand their DDoS experiences. Most were network services managers, senior systems engineers, systems administrators and directors of IT operations. In all, 1,000 people from 26 different industries shared responses about attacks, defenses, ongoing concerns, risks and financial losses. more
Israel's entire voter registry was recently uploaded to a vulnerable voting management app which effectively left the data wide open for days. more
One of the big trends this year is spear phishing. These are phish attacks that are frequently (though not always) against high profile users. The purpose of these attacks is to steal sensitive data or get elevation of privilege inside the service by exploiting a software vulnerability within the user's computer that transmits usernames and passwords back to the phisher. more
In what seems to have started with a blog post by reverse engineer Halvar Flake, and subsequent blog postings from other experts in the know, the details of the recently announced DNS vulnerability was quite likely made public today. The DNS flaw was found earlier this year by security researcher Dan Kaminsky and earlier this month announced publicly along with various tools and patches provided by numerous vendors... more
The outbreak of COVID-19 has caused worldwide disruption -- for whole nations and their economies. Unfortunately, there will be some side effects for businesses. A number of brands will disappear from the streets and shelves, as businesses that fail to weather the storm will have to fold. Companies that do survive will likely focus more on their core markets, pulling brands out of higher risk, less profitable markets... more
"As flood waters from Tropical Storm Irene swamped the Waterbury state office complex, seven employees from the Vermont Agency of Human Services rushed inside to rescue computer servers that are critical for processing welfare checks and keeping track of paroled prisoners living around the state," according to a story by Shay Totten on the 7days blog Blurt. Two of the employees - network administrator Andrew Matt and deputy chief information officer Darin Prail - lost their cars in the parking lot as the river rose but kept on working to assure that our servers were not lost. "We didn't know how much time we had," Matt said, "and our job was to save the servers." more
In my last blog post about Zoom, I noted that the company says "that critics have misunderstood how they do encryption." New research from Citizen Lab show that not only were the critics correct, Zoom's design shows that they're completely ignorant about encryption. When companies roll their own crypto, I expect it to have flaws. I don't expect those flaws to be errors I'd find unacceptable in an introductory undergraduate class, but that's what happened here. more
According to news reports, part of the EU's cybercrime strategy is "remote search" of suspects' computers. I'm not 100% certain what that means, but likely guesses are alarming. The most obvious interpretation is also the most alarming: that some police officer will have the right and the ability to peruse people's computers from his or her desktop. How, precisely, is this to be done? Will Microsoft and Apple – and Ubuntu and Red Hat and all the BSDs and everyone else who ships systems – have to build back doors into all operating systems? more
The indicators of compromise (IOCs) outlined in my last blog post can be used as a baseline for developing intrusion sets and tracking attack campaigns and threat actors. When launching an attack, threat actors use a variety of vectors and infrastructure, which Verisign iDefense analysts -- as well as analysts across the cybersecurity community -- correlate to group attacks, tracking actors and determining attack methods. more
Close to 773 million unique email addresses and 22 million unique passwords were found to be hosted on cloud service MEGA. more
The world is abuzz this week with some flaming malware - well "Flame" is the family name if you want to be precise. The malware package itself is considerably larger than what you'll typically bump into on average, but the interest it is garnering with the media and antivirus vendors has more to do with the kinds of victims that have sprung up - victims mostly in the Middle East, including Iran - and a couple of vendors claiming the malware as being related to Stuxnet and Duku. more
UK registry Nominet has enabled the deployment of domain name system security extensions (DNSSEC) for 9.4 million second level .uk domains. Completing the rollout represents over a year's work and marks an important milestone in making the web a more trusted environment for UK consumers and businesses, says Nominet, which is responsible for running the .uk internet infrastructure. more
Most of us, when we go to a website and see the little lock at the top of the browser, don't think twice and trust that we are communicating with the right company or organization. However, this is no longer the case because of a rather radical development that has largely occurred without notice or intervention by almost everyone. The web now has its own rapidly spreading version of CallerID spoofing that is about to get worse. more
There was a period of time not long ago in which signature-based threat detection was cutting-edge. Antivirus, intrusion detection systems (IDS), data leakage prevention (DLP), content filtering and even anomaly detection systems (ADS) all continue to rely heavily upon static signatures. In recent years vendors have shied away from discussing their dependence on such signatures -- instead extolling supplemental "non-signature-based" detection technologies. more
