Seems like the cyber-cons don’t completely rely upon their
own tight-fist web-crime methods and hence have resorted to incapacitating
their rivals in terms of destroying the payment data drawn out via the online
sites. As a result the victimized participant faces a humongous loss and a
seriously jeopardized reputation.
The par takers of this feud have clearly started thinking of
this as a game and they tend to clash up on the actual victim’s server.
Reportedly, the parties that are a part of this whimsical
rivalry strife belong to the “MageCart.” Groups.
One of the independent security researchers, belonging to a
well-established organization, had published a couple of reports instating the
codes that were used by "MageCart" group 9 in the attempt of destroying their
rivals’ manoeuvres.
The stores used as battlefield in the strife were, "B.Liv" online (a cosmetics shop) and "Umbro Brazil."
The code which was used by group 9 was obfuscated and could
easily sense the incidence of other web-skimming tools on the server.
To kick the data-poisoning system into effect, the domain
names used by the rival to eliminate the payment data are checked by the
skimming code. The moment it gets sensed the very moment a number that falls
between 0-9 is substituted at the last in the card number.
The moment a rival skimmer is sensed, the card data gets
seized immediately and the last number gets changed, rendering the data futile.
Such a minor alteration in the card’s number is more than
enough to render the data useless.
The rival would then attempt to sell the card with no useful
material in it on the dark web only to hamper his reputation vastly. The black
market is all about status and once that is smashed into pieces by unsatisfied
customers, the seller would stand nowhere.
This strategic approach of the cyber-cons towards their competition
has been spotted previously as well, in case of crypto-mining.
“Magecart” specifically exploits the third-party scripts
loads during checkout. The website owners should eliminate pages that exhibit
payment details or transaction data to keep themselves and their sites safe.
