The 2019 UN IGF is right now being held in Berlin and entering the last day. There has been a wide range of exciting discussions. It is a huge step forward that this year's IGF has been able to bring a plethora of topics together under a framework of thinking after the efforts done by the UN Secretary-General António Guterres' High-Level Panel on Digital Cooperation (The Age of Digital Interdependence) and by German scholars' engagement with all the stakeholders... more
In an article for the Financial Times, Mr Hannigan -- the chief of the British spy agency GCHQ said: "I understand why they [US technology companies] have an uneasy relationship with governments. They aspire to be neutral conduits of data and to sit outside or above politics." "But increasingly their services not only host the material of violent extremism or child exploitation, but are the routes for the facilitation of crime and terrorism."... more
It is not uncommon for government agents to force technology companies to create or install malicious software in products in order to help them with surveillance. The American Civil Liberties Union (ACLU) has released a guide for developers that is intended to help preserve security and customers' privacy. more
As you've probably read, WikiLeaks has released a trove of purported CIA documents describing their hacking tools. There's a lot more that will be learned, as people work their way through the documents. For now, though, I want to focus on something that's being misreported, possibly because of deliberately misleading text by WikiLeaks itself. Here's the text from WikiLeaks... more
The recent discovery of the goto fail and heartbleed bugs has prompted some public discussion on a very important topic: what advice should cryptologists give to implementors who need to use crypto? What should they do? There are three parts to the answer: don't invent things; use ordinary care; and take special care around crypto code. more
Microsoft continues to integrate new artificial intelligence technology into its products and today announced a cybersecurity "copilot" to help companies track and defend against hacking attempts. This tool is part of Microsoft's attempt to dominate the fast-growing field of "generative" AI. more
Once again I find myself thinking about the nature of the asymmetric warfare threat posed by politically motivated DDoS (Estonia in 07, Korea in 02, and now China vs. CNN in 08). I keep thinking about it in terms of asymmetric warfare, a class of warfare where one side is a traditional, centrally managed military with superior uniformed numbers, weaponry, and skill. On the other we have smaller numbers, usually untrained fighters with meager weapons, and usually a smaller force. Historical examples include the North Vietnamese in the 20th century and even the American Revolution in the 18th century. Clearly this can be an effective strategy for a band of irregulars... more
In its security bulletin, Akamai's Security Intelligence Response Team (SIRT) reported on abuse of DNS Security Extensions (DNSSEC) when mounting a volumetric reflection-amplification attack. This is not news, but I'll use this opportunity to talk a bit about whether there is a trade-off between the increased security provided by DNSSEC and increased size of DNS responses that can be leveraged by the attackers. more
Layered security is a concept that's important for anyone who wants to create a strong, successful defense strategy to understand. This is a strategy that relies on the use of multiple lines of defense in an attempt to repel any potential attacks. For this reason, it's based on the principle that says "no single form of protection is enough to stop a determined cybercriminal. more
ChatGPT, the newly released language model, has quickly gained popularity and is used for various tasks, from automation to music composition. While having useful features like fast and easy-to-use code examples, it also has the ability to create sophisticated malware without malicious code. more
I came across an interesting article on Reuters today: "U.S. securities regulators formally asked public companies for the first time to disclose cyber attacks against them, following a rash of high-profile Internet crimes..." This is a pretty big step for the SEC. Requiring companies to disclose when they have been hacked shifts the action on corporations from something voluntary to something that they have to do. The question is do we want to hear about everything? more
What are your concerns around encryption? What questions do you have about the legal, technical and policy aspects of the increasing use of encryption? How does encryption help bring about a higher level of trust in the Internet? On Wednesday, May 25, the Internet Society and its Greater Washington, DC Chapter are hosting an "Online Dialogue About Encryption" to discuss all these questions and many more. more
The Electronic Frontier Foundation (EFF) has voiced concerns about the European Union's proposed Cyber Resilience Act (CRA), saying it could pose significant threats to open-source developers and cybersecurity. more
U.S. Congress is growing increasingly suspicious of the popular Russian anti-virus software provider, Kaspersky Lab. more
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
