Zeynep Tufekci on Facebook and Cambridge Analytica
Zeynep Tufekci is particularly cogent about Facebook and Cambridge Analytica. Several news outlets asked me to write about this issue. I didn't, because 1) my book manuscript is due on Monday (finally!), and 2) I knew Zeynep would say what I would say, only better....

GreyKey iPhone Unlocker
Some details about the iPhone unlocker from the US company Greyshift, with photos. Little is known about Grayshift or its sales model at this point. We don't know whether sales are limited to US law enforcement, or if it is also selling in other parts of the world. Regardless of that, it's highly likely that these devices will ultimately end...

Israeli Security Attacks AMD by Publishing Zero-Day Exploits
Last week, the Israeli security company CTS Labs published a series of exploits against AMD chips. The publication came with the flashy website, detailed whitepaper, cool vulnerability names -- RYZENFALL, MASTERKEY, FALLOUT, and CHIMERA -- and logos we've come to expect from these sorts of things. What's new is that the company only gave AMD a day's notice, which breaks...

Artificial Intelligence and the Attack/Defense Balance
Artificial intelligence technologies have the potential to upend the longstanding advantage that attack has over defense on the Internet. This has to do with the relative strengths and weaknesses of people and computers, how those all interplay in Internet security, and where AI technologies might change things. You can divide Internet security tasks into two sets: what humans do well...

The 600+ Companies PayPal Shares Your Data With
One of the effects of GDPR -- the new EU General Data Protection Regulation -- is that we're all going to be learning a lot more about who collects our data and what they do with it. Consider PayPal, that just released a list of over 600 companies they share customer data with. Here's a good visualization of that data....

E-Mailing Private HTTPS Keys
I don't know what to make of this story: The email was sent on Tuesday by the CEO of Trustico, a UK-based reseller of TLS certificates issued by the browser-trusted certificate authorities Comodo and, until recently, Symantec. It was sent to Jeremy Rowley, an executive vice president at DigiCert, a certificate authority that acquired Symantec's certificate issuance business after Symantec...

I recently blogged about the new National Academies report on the same topic. Here's a review of the National Academies...

New DDoS Reflection-Attack Variant
This is worrisome: DDoS vandals have long intensified their attacks by sending a small number of specially designed data packets to publicly available services. The services then unwittingly respond by sending a much larger number of unwanted packets to a target. The best known vectors for these DDoS amplification attacks are poorly secured domain name system resolution servers, which magnify...

Security Vulnerabilities in Smart Contracts
Interesting research: "Finding The Greedy, Prodigal, and Suicidal Contracts at Scale": Abstract: Smart contracts -- stateful executable objects hosted on blockchains like Ethereum -- carry billions of dollars worth of coins and cannot be updated once deployed. We present a new systematic characterization of a class of trace vulnerabilities, which result from analyzing multiple invocations of a contract over its...

Intimate Partner Threat
Princeton's Karen Levy has a good article computer security and the intimate partner threat: When you learn that your privacy has been compromised, the common advice is to prevent additional access -- delete your insecure account, open a new one, change your password. This advice is such standard protocol for personal security that it's almost a no-brainer. But in abusive...

Extracting Secrets from Machine Learning Systems
This is fascinating research about how the underlying training data for a machine-learning system can be inadvertently exposed. Basically, if a machine-learning system trains on a dataset that contains secret information, in some cases an attacker can query the system to extract that secret information. My guess is that there is a lot more research to be done here. EDITED...
