Cyber Security Risks In Social Media
Banking
Introduction
Social Media is the most used platform on day-to-day basis by millions of people around the
world.
Social media banking is the usage of social platforms such as Facebook, twitter, WhatsApp
for Marketing, communication, for collecting feedback and reactions and to perform Banking
Operations such as Transactions, Account summary and status enquiry, etc. We have
observed using social media as a platform in 2 ways.
1. Non-Banking Operations – Marketing, Branding, Feedback, Business Analysis.
2. Banking Operations – Transactions, Communications and alerts, Account summary,
status of the account or cards, reporting fraud/stolen card details etc.
Use cases of Social Media Banking
1. Global Banks Using Twitter for Banking:
Money can be sent using twitter accounts connected to Bank accounts, or it would have
other options of receiving and sharing passcode and OTP with the receiver for authorizing a
transaction.
2. WhatsApp Banking service:
Absa Banking app (Africa) has introduced WhatsApp Banking to help customer receive
updates or avail services via the WhatsApp messaging platform. On typing Help as a
message, you can find out the full list of services available on WhatsApp. It is easy to use—
simply type a keyword like or type the number against the service like “1” and follow the
steps on screen.
3. CaixaBank Facebook Banking Application:
CaixaBank has launched a Facebook application that allows users to view their bank
accounts and perform transactions via the social network. This is the first platform of its kind
from a European bank, allowing customers to check account balances, make micro-
donations and contract personalized card services. The new CaixaBank service for
Facebook will also provide quick access to the bank’s primary online channel, Linea
Abierta. Once activated, users can open the application via their personal profile or the
bank’s Facebook page. Users will have to enter their Linea Abierta username and password
each time the service is opened, as the service is located in a fully secure and private
environment that can only be opened by each customer. At no time will Facebook have
access to any personal or bank information.
Example: Australian Common Wealth bank using Facebook and other Banks using
Messenger.
Organizational Risks Associated with Social Media Banking:

media banking issues created the “Social Media: Consumer Compliance Risk Management
Guidance”
Risk Areas for Social Media banking are as follows.

Control: Financial institutions should consider the use of social media monitoring tools and
techniques to identify heightened risk, and respond appropriately. Financial institutions
should have appropriate policies in place to monitor and address in a timely manner the
fraudulent use of the financial institution’s brand, such as through phishing or spoofing
attacks.
