Anonymizing 1 Your Activities In our daily lives we like to have a certain level of privacy. We have curtains on our win- dows, doors for our offices, and even special screen protectors for computers to keep out prying eyes. This idea of wanting privacy also extends to the use of the Internet. We do not want people knowing what we typed in Google, what we said in our Instant Message conversations, or what websites we visited. Unfortunately, your private information is largely available if someone is watching. When doing any number of things on the Internet, there are plenty of reasons you might want to go incognito. However, that does not mean you’re doing anything wrong or illegal. he justification for anonymity when researching malware and bad guys is pretty Tstraightforward. You do not want information to show up in logs and other records that might tie back to you or your organization. For example, let’s say you work at a finan- cial firm and you recently detected that a banking trojan infected several of your systems. You collected malicious domain names, IP addresses, and other data related to the malware. The next steps you take in your research may lead you to websites owned by the criminals. As a result, if you are not taking precautions to stay anonymous, your IP address will show up in various logs and be visible to miscreants. If the criminals can identify you or the organization from which you conduct your research, they may COPYRIGHTEDchange tactics or go into hiding, MATERIAL thus spoiling your investigation. -
An Investigation Into the Security and Privacy of Ios VPN Applications
An Investigation Into the Security and Privacy of iOS VPN Applications Jack Wilson Division of Cybersecurity School of Design and Informatics Abertay University, Dundee A thesis submitted for the degree of Bachelor of Science with Honours in Ethical Hacking 1st May 2018 Word Count: 11,448 Abstract Due to the increasing number of recommendations for people to use VPN’s for privacy reasons, more app developers are creating VPN apps and publishing them on the Apple App Store and Google Play Store. In this ‘gold rush’, apps are being developed quickly and, in turn, not being developed with security fully in mind. This paper investigated a selection of free VPN applications available on the Apple App Store (for iOS devices) and test the apps for security and privacy. This includes testing for any traffic being transmitted over plain HTTP, DNS leakage and transmission of personally-identifiable information (such as phone number, IMEI 1, email address, MAC address) and evaluating the security of the tunnelling protocol used by the VPN. The testing methodology involved installing free VPN apps on a test device (an iPhone 6 running iOS 11), simulating network traffic for a pre-defined period of time and capturing the traffic (either through ARP spoofing, or through a proxy program such as Burpsuite). This allows for all traffic to be analysed to check for anything being sent without encryption. Other issues that often cause de-anonymisation with VPN applications such as DNS leakage can be tested using websites such as dnsleaktest.com. The research found several common security issues with the VPN applications that were tested, with a large majority of the applications tested failing to implement HTTPS. -

Best VPN Services in 2017 (Speed, Cost & Usability Reviews)
10/8/2017 Best VPN Services in 2017 (Speed, Cost & Usability Reviews) Best VPN Services VPN Reviews & In-Depth Comparisons Brad Smith Sep 18, 2017 With the help of John & Andrey (https://thebestvpn.com/contact-us/), we’ve put together a list of best VPNs. We compared their download/upload speed, support, usability, cost, servers, countries and features. We also analyzed their TOS to see if they keep logs or not and whether they allow P2P and work with Netflix. here’s a link to the spreadsheet (https://docs.google.com/spreadsheets/d/11IZdVCBjVvbdaKx2HKz2hKB4F Z_l8nRJXXubX4FaQj4/) You want to start using a VPN, but don’t know which software/service to use? In this page, we’ve reviewed 30+ most popular VPN services (on going process). In order to find out which are best VPNs, we spent some time on research and speed testing: 1. Installed 30+ VPN software on our personal devices, such as Windows, Mac, Android and iOS and compared their usability. 2. Performed Download/Upload speed tests on speedtest.net to see which had best performing servers. 3. Double checked if they work with Netflix and allow P2P. 4. Read their TOS to verify if they keep logs or not. 5. Compared security (encryption and protocols). That means we’ve dug through a large number of privacy policies (on logging), checked their features, speed, customer support and usability. If you know a good VPN provider that is not listed here, please contact us and we’ll test it out as soon as possible. 5 Best VPNs for Online Privacy and Security Here are the top 5 VPN services of 2017 after our research, analysis, monitoring, testing, and verifying. -

Online Security for Independent Media and Civil Society Activists
Online Security for Independent Media and Civil Society Activists A white paper for SIDA’s October 2010 “Exile Media” conference Eric S Johnson (updated 13 Oct 2013) For activists who make it a priority to deliver news to citizens of countries which try to control the information to which their citizens have access, the internet has provided massive new opportunities. But those countries’ governments also realise ICTs’ potential and implement countermeasures to impede the delivery of independent news via the internet. This paper covers what exile media can or should do to protect itself, addressing three categories of issues: common computer security precautions, defense against targeted attacks, and circumventing cybercensorship, with a final note about overkill (aka FUD: fear, uncertainty, doubt). For each of the issues mentioned below, specific ex- amples from within the human rights or freedom of expression world can be provided where non-observance was cata- strophic, but most of those who suffered problems would rather not be named. [NB Snowden- gate changed little or nothing about these recommendations.] Common computer security: The best defense is a good … (aka “lock your doors”) The main threats to exile media’s successful use of ICTs—and solutions—are the same as for any other computer user: 1) Ensure all software automatically patches itself regularly against newly-discovered secu- rity flaws (e.g. to maintain up-to-date SSL certificate revocation lists). As with antivirus software, this may cost something; e.g. with Microsoft (Windows and Office), it may re- quire your software be legally purchased (or use the WSUS Offline Update tool, which helps in low-bandwidth environments). -

Over 20 million people from 190 countries use the Hotspot Shield VPN A VPN client for safe Web access clients. The project is so massive and complex that it requires a large team of professionals to work on it. Several teams work simultaneously at the server side, improve the traffic tunnelling protocol, support multiple applications and ensure that company users are safe.

Identifying and Reducing Usability Issues in Anonymity Systems
Why Johnny Can’t Blow the Whistle: Identifying and Reducing Usability Issues in Anonymity Systems Greg Norcie Jim Blythe Kelly Caine L Jean Camp Indiana University Information Sciences Institute Clemson University Indiana University [email protected] [email protected] [email protected] [email protected] Abstract—Tor is one of the most widely used anonymity Tor uses onion routing [24] to prevent third parties from networks in the world.

The term “onion routing” refers to Tor’s layered of anonymity tools, including Tor, can be hindered by a lack of usability. Therefore, enhancing Tor’s usability and making it encryption, analogous to the layers in an onion, which prevents easier for more people to use Tor successfully increases security third parties (including Tor nodes) from observing the content for all Tor users. To enhance Tor usability we begin by identifying of packets in transit. Tor also prevents the linkage of the source stop-points which may act as barriers to using the Tor Browser and destination of any packet in the Tor network. Of course, Bundle (TBB). We suggest changes based on our analysis of there are attacks that threaten privacy even when using Tor, these stop-points. To follow through, in our second study we test whether the changes we recommended to the Tor Project are including subversion via control of malicious nodes and timing effective in increasing usability, and find a significant decrease attacks.
