Living dangerously in the hacker’s shadow in a ‘less-cash’ economy- India

Vulnerabilities exist

Vulnerabilities associated with payments systems exist and hence signal the need for caution. Examples follow.

Compromised applications: The most plausible vulnerability with payment applications is the presence of other applications on a consumer's mobile phone. If a user has an alternative keyboard application, it could be a risk in terms of logging passwords and pins while performing bank transactions. It is also possible that a user inadvertently downloads an application while browsing the web that could compromise his/her phone data and transactions. With some payment wallets, anyone having casual access to a user's mobile phone could be a vulnerability as application PINs are not set up.


Man-in-middle vulnerability: In this scenario, a hacker gets access to either the servers on the telecom network, the payment wallet or the bank's networks. Listening to the communication (despite being encrypted) could still be considered a risk. This type of vulnerability could be considered to be more esoteric. Hacking of a bank's or NPCI's servers could end up exposing personal details of users, while hacking of a mobile (GSM) network (A5/1 encryption has known vulnerabilities) could expose all communication, especially the USSD-based transactions.

Home loan or Car loan calculator

A good EMI calculator http://www.bankbazaar.com/home-loan-emi-calculator.html Tax benefits: Tax benefit is only on the interest paid on the loan taken. Prohibition of Usury in Various Religions Hinduism The earliest such record derives from the   Vedic   texts of Ancient India (2,000-1,400 BC) in which the "usurer" ( kusidin ) is mentioned several times and interpreted as any lender at interest.  More frequent and detailed references to interest payment are to be found in the later   Sutra   texts (700-100 BC), as well as the Buddhist   Jatakas   (600-400 BC).  It is during this latter period that the first sentiments of contempt for usury are expressed.  For example, Vasishtha, a well known Hindu law-maker of that time, made a special law which forbade the higher castes of   Brahmanas   (priests) and   Kshatriyas   (warriors) from being usurers or lenders at interest.  Also, in the   J...
