ICT Security-Sécurité PC et Internet

This is a classic identification problem, and efficacy depends on two things: false positives and false negatives.

False positives: Any app will have a precise definition of a contact: let's say it's less than six feet for more than ten minutes. The false positive rate is the percentage of contacts that don't result in transmissions. This will be because of several reasons. One, the app's location and proximity systems -- based on GPS and Bluetooth -- just aren't accurate enough to capture every contact. Two, the app won't be aware of any extenuating circumstances, like walls or partitions. And three, not every contact results in transmission; the disease has some transmission rate that's less than 100% (and I don't know what that is).

False negatives: This is the rate the app fails to register a contact when an infection occurs. This also will be because of several reasons. One, errors in the app's location and proximity systems. Two, transmissions that occur from people who don't have the app (even Singapore didn't get above a 20% adoption rate for the app). And three, not every transmission is a result of that precisely defined contact -- the virus sometimes travels further.

Assume you take the app out grocery shopping with you and it subsequently alerts you of a contact. What should you do? It's not accurate enough for you to quarantine yourself for two weeks. And without ubiquitous, cheap, fast, and accurate testing, you can't confirm the app's diagnosis. So the alert is useless.

Websites Use Session-Replay Scripts to Eavesdrop on Every Keystroke and Mouse Movement

The security researchers at Princeton are posting

You may know that most websites have third-party analytics scripts that record which pages you visit and the searches you make. But lately, more and more sites use "session replay" scripts. These scripts record your keystrokes, mouse movements, and scrolling behavior, along with the entire contents of the pages you visit, and send them to third-party servers. Unlike typical analytics services that provide aggregate statistics, these scripts are intended for the recording and playback of individual browsing sessions, as if someone is looking over your shoulder.

The stated purpose of this data collection includes gathering insights into how users interact with websites and discovering broken or confusing pages. However the extent of data collected by these services far exceeds user expectations; text typed into forms is collected before the user submits the form, and precise mouse movements are saved, all without any visual indication to the user. This data can't reasonably be expected to be kept anonymous. In fact, some companies allow publishers to explicitly link recordings to a user's real identity.

The researchers will post more details on their blog; I'll link to them when they're published.

Security researcher and blogger Bruce Schneier has a new essay up, arguing that there’s a single body out there carrying out a systematic attempt to test the defenses of the internet’s fundamental infrastructure, presumably with the intention of one day breaking those defenses. While the sources for the article are anonymous, they hardly need naming since Schneier makes it clear that his research has collected insight from virtually all major internet companies, from large service providers like AT&T all the way to organizing bodies like Verisign or potentially even ICANN itself. Somebody is searching for weaknesses in the sorts of places that many assume you’d only attack for one reason: crashing all or a large portion of the internet.
