I spent the last week at the RSA security conference in fear of getting sick before my talk on Friday, the last day of the conference. During that time I was nearly obsessive about using hand sanitizer to protect me against any germs I might be getting from shaking hands, or touching surfaces.
Security researchers discovered a very sophisticated watering hole attack against Forbes.
There is a major trend towards increasingly targeted cyber attacks, from advanced persistent threats (APT), to spear phishing. Now we are seeing targeting applied to watering hole attacks. I think of this as the sniper at the watering hole. (more…)
Right after the Lizard Squad finished with a DDOS attack on the PSN and XBOX networks, they launched an attack against the Tor anonymity system. The attack was simple, set up enough Tor relays to be able to identify a significant fraction of Tor users and connect them with their activity. They got caught because they were bozos (perhaps intentionally). They did the attack hard and fast, which made it easy to identify the rogue relays, and they bragged about it (which told people to look for the attack). (more…)
The Chaos Computer Club recently announced that their website was being blocked by Vodefone as part of their participation in the “Great Firewall of Britain”. This is somewhat concerning as they don’t seem to match any of the criteria for blocking that have been announced. This also blocks access to information and tickets for their upcoming conference. Many people predicted (me, EFF, and many others) that this censorship system would inevitable overreach when it was first announced. (more…)
In two separate cases recently Uber has, or has talked about, abusing its information about their customer’s movements.
First a Buzzed reporter Johana Bhuiyan was told that she was tracked on the way to a meeting by Josh Mohrer, general manager of Uber New York.
Next Emil Michael, SVP of business for Uber, talked at a private dinner about the possibility of using the information Uber has about hostile reporters to gather dirt on them. (more…)
Kaspersky recently announced the discovery of a new Advanced Persistent Threat (APT) that they are calling DarkHotel. This is in the fine tradition of giving all newly discovered hackers or vulnerabilities clever and evil sounding names. In this case they have found something quite interesting.
For the last 7 years a group has been systematically targeting executives and government officials staying at high end hotels. They hack their computers and grab their files, sniff their keyboards, and install virus that can then spread within the victim’s organization. (more…)
A couple of months ago researcher Karsten Nohl demonstrated a security vulnerability that he called BadUSB. Basically it was a demonstration that an attacker could alter the firmware in a USB device to automatically attack anything it was plugged in to. At the recent DerbyCon, researchers Adam Caudill and Brandon Wilson demonstrated their version of the attack and released sample code for how to implement it. This really opens pandora’s box.
The problem here is that this is not actually a bug in USB. It is exactly how USB is designed to work (as insecure as that might be), and changing that behavior is likely to break a lot of other things. A good and effective fix for this vulnerability is probably years away.
In the mean time, take great care with USB devices. My suggestion is to never use another person’s USB device. Don’t use USB to transfer files, and make sure that any USB devices you do use are obtained directly in unopened packaging. There could still be exploits introduced in manufacturing, but at least you are as safe as reasonably possible.
Apple is getting taken to task for a couple of security issues.
First, their recently announced “Random MAC address” feature does not appear to be as effective as expected. The idea is that the iOS 8 device will use randomly generated MAC addresses to ping WiFi base stations when it is not actively connected to a WiFi network. This allows your phone to identify known networks and to use WiFi for enhanced location information without revealing your identity or allowing you to be tracked. Unfortunately the MAC only changes when the phone is sleeping, which is really rare with all the push notifications happening all the time. The effect is that the “random” MAC addresses are changed relatively infrequently. The feature is still good, but needs some work to be actually very useful.
Second, people are noticing their passwords showing up in Apples iOS 8 predictive keyboard. The keyboard is designed to recognize phrases you type frequently so it can propose them to you as you type, thus speeding message entry. The problem is that passwords often follow user names, and may be typed frequently. Research is suggesting that the problem is from websites that fail to mark their password fields. Apple is smart enough to ignore text in known password fields, but if it does not know that it is a password, then the learning happens. It is not clear that this is Apple’s fault, but it is still a problem for users. Auto-fill using the latest version of 1Password should protect against this.
Since it was introduced, Apple has had the ability to decrypt the contents if iPhones and other iOS devices when asked to do so (with a warrant).
Apple recently announced that with iOS 8 Apple will no longer be able to do so. Predictably, there has been a roar of outrage from many in law enforcement. [[Insert my usual rant about how recent trends in technology have been massively in favor of law enforcement here]].
This is really about much more than keeping out law enforcement, and I applaud Apple for (finally) taking this step. They have realized what was for Anonymizer a foundational truth. If data is stored and available, it will get out. If Apple has the ability to decrypt phones, then the keys are available within Apple. They could be taken, compromised, compelled, or simply brute forced by opponents unknown. This is why Anonymizer has never kept data on user activity.
Only by ensuring that they can not do so can Apple provide actual security to it customers against the full range of threats, potentially least of which is US law enforcement.
