  • Can email addresses be just a few characters?

    Can email addresses be just a few characters?

    Received a question asking “can email addresses be just a few characters?”

    Yes.

    Reference links

    • http://www.faqs.org/rfcs/rfc2822.html
    • http://tools.ietf.org/html/rfc5322#section-3.4.1
    • http://tools.ietf.org/html/rfc6531#section-3.3

     

    Many email providers limit how short or how long the email address can be.

    As examples, Gmail (which provides addresses @gmail.com) rejects requested email addresses less than 6 characters to prevent spam.  See https://support.google.com/mail/answer/7993

    Microsoft (Outlook.com and “Hotmail.com”) addresses can contain only letters, numbers, periods (.), hyphens (-), and underscores (_).

    No special characters, accented letters, or letters outside the Latin alphabet.

    If you are setting up your own email server, or using Google Apps, you can pick what you want to be a valid email address. For example, at the TTCS, we can have 1@ttcsweb.org, or even !@ttcsweb.org if we choose.

    As long as it complies with Internet rules, any email provider can make their email usernames however they want.

     

  • Whether email accounts can be hacked and how

    Whether email accounts can be hacked and how

    Received a question asking “whether email accounts can be hacked and how”

    Yes, email accounts can be hacked to allow unauthorized persons to access your email account .  Typically, this can be done by several approaches (or a combination of them):

    (Update : 6:50 pm May 21 – switched article to headings instead of ordered list)

     

    Phishing

    This is when you are deceived into entering your username and password at a bogus website masquerading as the legitimate site. See “How the Syrian Electronic Army Hacked The Onion” http://theonion.github.io/blog/2013/05/08/how-the-syrian-electronic-army-hacked-the-onion/ as an example of a phishing emails used to get user credentials.

     

    Installing malicious software or spyware

    Spyware on a computer can monitor keystrokes and eventually obtain your email username and password as you use the computer to access the account.

    Spyware is typically installed on your computer by

    • software exploits – surreptitiously by taking advantage of software flaws or vulnerabilities (often the web browser and the addons installed in your web browser) on your computer. Such security flaws allows for software to be installed without your knowledge by visiting a malicious website.
    • bundling such spyware with third party software obtained from unreliable sources
    • deceiving the user to install software via banner ads or by forged emails from one of your friends or organisation you work with, asking you to view/run an attachment.

     

    Social Engineering

    Persons use email addresses to sign up for various online services/websites. Most (if not all) services allow for the password to user’s accounts to be reset, in case you have forgotten your password. Because such services use different details about you to verify your identify, information about you gleaned from one service (e.g your birthday posted on Facebook, WHOIS information from your domain name you registered) can be used by an attacker to obtain your password at another service. A Wired editor wrote a detailed article when this happened to him: http://www.wired.com/gadgetlab/2012/08/apple-amazon-mat-honan-hacking/all/.  Another interesting article : https://medium.com/tech-talk/280c753b1145

     

    Not logging out of your account from a shared or public computer

    Not logging out of your account from a shared or public computer means that another person with access to the machine can access your account.

     

    Poor password security practices

    Email accounts has been hacked from people “guessing” the answers to the recovery/security question to reset the password. Easy questions like your spouse’s name or favourite pet can be gleaned from information published on social networks.

    Other poor security practices include using simple passwords that are easy to guess (eg “password” for the password) and using the same username and password for multiple services. When one service is compromised resulting in their user accounts and password information being stolen or leaked on the Internet, all other services that use the same username and password are at risk.

     

    Password sniffing

    Typically many public wifi networks are not encrypted, which means that other devices on the wireless network can eavesdrop and monitor network traffic. This means that if you use your username and password on such a network, your login information can be copied for later use by such other devices.

       

    Any suggestions for this post on how else can email accounts be hacked?

  • Columbus Networks, Cable & Wireless enter strategic alliance, will form joint venture company to sell bandwidth to companies in Caribbean and Americas region

    Columbus Networks, Cable & Wireless enter strategic alliance, will form joint venture company to sell bandwidth to companies in Caribbean and Americas region

    Cable and Wireless and Columbus Networks have entered into a strategic alliance and will form  a joint venture company called CNL-CWC Networks Ltd. to provide international wholesale bandwidth to communication companies in the Caribbean and America’s Region.

    Via the press release on Cable and Wireless Communications (CWC’) website dated May 13 2013 :

    13 May, 2013
    CABLE & WIRELESS COMMUNICATIONS

    CWC agrees strategic alliance with Columbus Networks

    Cable & Wireless Communications Plc (“CWC”) today announces it has entered into a strategic alliance with Columbus Networks Ltd (“Columbus”) to develop its international wholesale capacity business.

    Under the alliance, CWC and Columbus will form a joint venture in the pan-America region which will provide international wholesale capacity to both companies, as well as to third party carriers. CWC and Columbus operate substantial and largely complementary sub-sea cable networks in the Caribbean and Central American region – the joint venture will have a network platform of  approximately 42,000 kilometres with connectivity to 42 countries.

    The alliance positions CWC strongly to meet the data capacity demands of its retail operations in the future, as well as optimising its capital expenditure commitment to its undersea cable networks. Demand for data capacity is growing rapidly in this region, driven by the increasing availability of, and consumer demand for, mobile data and fixed broadband services.

    The joint venture, which launched today, will initially operate on an agency basis by providing joint sales and marketing services for each of CWC’s and Columbus’ international wholesale capacity services. Columbus has a 72.5% majority share in, and management control of, the joint venture and CWC has a 27.5% share with appropriate minority protections.

    The alliance will be broadened within the next two years with Columbus and CWC contributing their sub-sea and related assets into the joint venture company, subject to obtaining regulatory approvals and certain other conditions being met.

    Until then, Columbus and CWC will retain complete ownership and control of their respective existing networks in the region.

    Once the applicable approval requirements and conditions have been met, the joint venture will
    then assume ownership and management control of the international wholesale capacity
    operations of CWC and Columbus and all new investments in infrastructure will be made, and
    owned by it.

     

    There is another press release on Cable and Wireless website on the Joint Venture :

    BRIDGETOWN, BARBADOS, AND LONDON – (May 13, 2013) – Columbus Networks and CWC Wholesale Solutions today announced the formation of a joint venture to provide
    expanded wholesale bandwidth capacity to global, regional and local communications companies in the Caribbean and Americas Region. The joint venture company will be called CNL-CWC Networks Ltd.
    In addition to the joint venture, CWC Wholesale Solutions, a subsidiary of Cable & Wireless Communications, has entered into a separate services agreement with Columbus Networks under which Columbus Networks will provide CWC Wholesale Solutions certain operation and monitoring services.

    Columbus Networks and CWC Wholesale Solutions operate complementary networks in the rapidly growing region. After completing multiple network interconnections, the joint venture will offer wholesale customers an expanded network platform that spans more than 42,000 kilometers and reaches more than 42 countries in the region.

    The joint venture company will serve as the sales agent of both Columbus Networks and CWC Wholesale Solutions for international wholesale capacity. Columbus Networks will be the managing partner in the joint venture. CWC Wholesale Solutions will provide support and management resources. Columbus Networks and CWC Wholesale Solutions will retain ownership and control of their respective existing networks in the region.

    “Wholesale customers will be able to take advantage of expanded network reach and service benefits by doing business with a company that can provide more bandwidth and broader reach, faster and better,” said Paul Scott, president of Columbus Networks. “With this joint venture, one plus one equals three.”

    In the coming months, customers will begin to enjoy much greater route choice, improved reliability and higher performance as the joint venture rolls out innovative, new service offerings spanning clear channel services, IP transit, carrier Ethernet and carrier MPLS.
    “We have been investing heavily in recent years to upgrade existing networks and build entirely new subsea links such as CBUS and East West Cable,” said Simeon Irvine, chief  executive of CWC Wholesale Solutions. “By creating this joint venture, CWC Wholesale Solutions can expand its network reach and increase the diversity and security of supply for our customers and those of Columbus.”

    The interconnected networks will enable more self-healing fiber optic rings with a future planned migration to a fully meshed network environment that will significantly
    improve the region’s access to international capacity and better meet the increasing demands for reliability and performance.
