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…)
It looks like people who care about Internet anonymity need to look outside Canada for their providers. It is not just a concern that the Canadian government would be able to subpoena the information, but it is also vulnerable to insider and external attack. If the data exists, it will eventually leak.
Starting today Canadian Internet providers are required to forward copyright infringement notices to their subscribers. This notification scheme provides a safe harbor for ISPs but is also expected to result in a surge in piracy settlement schemes. The new law further causes trouble for VPN providers, who are now required to log customers for at least six months.
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…)
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…)
Two new attacks on Tor were recently announced.
Recently a colleague was reading a blog post by a Russian based VPN provider which talked about their privacy stance. He was incredulous. “Why would anyone trust a Russian VPN company?!?!”
It is a reasonable question about many locations. Russia, China, Iran, and many other companies are justifiably known for Internet monitoring and censorship. Of course, in the post Snowden era, a lot of attention has been focused on US surveillance as well.
I think that many people have the feeling that they should trust anyone but their own governments. After all, foreign intelligence services are unlikely to do anything about any intercepts unless they see some kind of global doomsday scenario. You might worry that your local intelligence agency could pass along information to local law enforcement, but that too seems generally unlikely. Exposing such intercepts would also expose sources and methods, which are some of the most highly protected secrets out there.
To me the question is what the VPN / Privacy provider is ALLOWED to keep private. It is clear that many governments put a huge amount of pressure, or actually pass laws, on companies to keep all kinds of user activity records. Interestingly that is not the case in the United States.
Anonymizer has no requirement to keep any records about what our users do through our service, or any way to identify associate any activity with a given user. Our systems are architected so that we don’t need to refuse to provide any of that information, we are simply incapable of doing so.
The recent incident where attackers posted usernames and passwords for compromised Dropbox accounts really shows the importance of practicing good password hygiene.
GigaOm has one of many articles describing the actual events. The short version is that some hackers have been posting usernames and passwords to Dropbox accounts on a Pastebin page. Dropbox says that they have not been compromised, and that the passwords were actually taken from other websites or through other methods.
If this is true, and it seems reasonable, then those who have been compromised became victims because they reused their passwords across multiple websites. That is probably a bigger security error than choosing weak passwords in the first place.
The security at websites varies widely, usually based on the sensitivity of the information on that site. Banks tend to have better security than news sites or discussion sites. If you use the same password with all these sites, then if any of them is compromised the attacker can simply try your username / password on every other interesting website to see if they work there too.
The solution is to use a different password on every website. They should not be simply modifications of each other but actually completely different passwords. Additionally they should be long and random. This means that they will be impossible to remember, but a password manager or password vault can take care of that for you. It will generate the strong random passwords, fill in the forms for you, and sync between your various computers and other devices. There is no excuse not to use unique and strong passwords with every website, and you will be much safer if you do.
In the article below Attorney General Eric Holder said ““It is fully possible to permit law enforcement to do its job while still adequately protecting personal privacy”
This is simply not true, and harkens back to the discredited arguments made by the FBI in the 1990’s about the Clipper Chip. It is hard enough to make secure computing systems, and we are not very good at it as all the breaches demonstrate. Intentionally introducing a vulnerability, which is the essential nature of back door or law enforcement access, is madness. If there is a back door, then keys exist, and can be compromised or reverse engineered. It is an added complexity to the system, which is almost certain to introduce other vulnerabilities. Its use would not be restricted to the US. Once it exists every government will demand access.
Social media and the cloud have tilted the balance of power absurdly towards law enforcement. This argument that they must retain access to encrypted cell phones is fatuous.
