Cybercriminals Benefitting from Stalled Privacy/Proxy Policy

We've seen alarmingly BIG increases in multiple abusive behaviors – like phishing, hacking and malware – that often leverage the domain name system (DNS) and privacy/proxy services. Cybercriminals capitalize on gaps in DNS security measures, and ICANN is holding the door open for them by failing to implement their privacy/proxy policy. If you are ever targeted, you are not alone. more

Cybercriminals Weaponize Bulk-Registered Domain Names

Domain names that can be rapidly acquired, used in an attack, and abandoned before they can be traced are a critical resource for cybercriminals. Some attacks, including spam and ransomware campaigns and criminal infrastructure operation (e.g., "botnets"), benefit particularly from the ability to rapidly and cheaply acquire very large numbers of domain names – a tactic known as bulk registration. more

Proactive Cybersecurity: What Small Businesses Can Actually Do

In the business world, there are two main paths a company can take with cybersecurity -- the reactive and the proactive approach. The problem with a purely reactive attitude is that it can easily put companies in constant firefighting mode. And for small companies with limited resources, this can turn out to be an increasingly uncomfortable place to be in.
With that in mind, experts today suggest proactive cybersecurity by monitoring suspicious activity and identifying risks before they turn into full-blown attacks. more

Threat Intelligence in Latter 2019: Overcoming the Same and New Challenges

Does threat intelligence (TI) work? I looked into that question last year, exploring the reasons why it actually doesn't and what can be done to remediate the situation. Since then, more companies have incorporated TI into their security processes, and many are still not getting the benefits they expect. What's causing the dissatisfaction? Interestingly, pretty much the same aspects... more

WHOIS Database Download: Proactive Defense Against the Rising Tide of BEC Fraud

How many times have you heard that humans are the weakest link in cybersecurity? The headlines have proven that over and over again. In particular, business email compromise or BEC (also known as email account compromise or EAC) scams, which typically target an employee with access to the financial resources of his company -- this could be a C-level executive or any high-ranking officer -- for fraud are still on a constant uphill trend. more

Why Passive DNS Matters in Cybersecurity

Imagine a scenario. Your website analysis shows that your page has stopped receiving visitors, yet there are no complaints that your domain is unreachable. Strange, isn't it? You are certainly wondering: What's going on? Where are my customers? You see, what happened is that you are facing the consequences of the lack of domain name system (DNS) security. more

A Dangerous, Norm-Destroying Attack

Kim Zetter has a new story out describing a very serious attack. In fact, the implications are about as bad as possible. The attack has been dubbed ShadowHammer by Kaspersky Lab, which discovered it. Briefly, some crew of attackers -- I suspect an intelligence agency; more on that below -- has managed to abuse ASUS' update channel and private signing key to distribute bogus patches. more

Putting Cyber Threats Into Perspective

As society uses more digital technologies we are increasingly also faced with its problems. Most of us will have some horror stories to tell about using computers, smartphones, and the internet. But this hasn't stopped us from using the technology more and more. I believe that most people would say that their lives would be worse without technology -- in developed countries but equally in the developing world. more

Some Thought on the Paper: Practical Challenge-Response for DNS

Because the speed of DNS is so important to the performance of any connection on the 'net, a lot of thought goes into making DNS servers fast, including optimized software that can respond to queries in milliseconds, and connecting DNS servers to the 'net through high bandwidth links. To set the stage for massive DDoS attacks based in the DNS system, add a third point: DNS responses tend to be much larger than DNS queries. more

Microsoft is Abandoning SHA-1 Hashes for Updates - But Why?

Microsoft is shipping a patch to eliminate SHA-1 hashes from its update process. There's nothing wrong with eliminating SHA-1 - but their reasoning may be very interesting. SHA-1 is a "cryptographic hash function". That is, it takes an input file of any size and outputs 20 bytes. An essential property of cryptographic hash functions is that in practice (though obviously not in theory), no two files should have the same hash value unless the files are identical. more
