"An attack on sharing information about users endangers e-wallet users and leads to millions of dollars worth of theft," reports GeoEdge, a company that specializes in cyber protection related to online and mobile advertising.
This is a new attack, unlike the traditional attacks where attackers submit malicious content through the advertising creative itself - the current attacker submitted his malicious content through a cookie sharing procedure (a string of letters or numbers, used to verify, track and store information about users).
It is estimated that over $ 20 million was stolen through the sophisticated scam.
"Large sites are unaware that the advertisements displayed on their domain can be a backdoor for intrusive attacks against users," said Amnon Ziv, CEO of GeoEdge. them.
The attack we uncovered was actually triggered by a cookie-sinking mechanism, each site being exposed to it whether or not it submits certain advertisements.
Such an attack spreads quickly and is therefore significant in terms of the extent of the potential damage - damaging a large mass of sites without any ability for the sites to defend themselves.
Especially these days, online protection for the big sites and private surfers is most necessary.
We have detected an increase in cyber attacks of various types over the past year and it is important to act accordingly, "he added. The
code loaded by the attacker without his knowledge alerts the user that his e-wallet is not valid and he must update a version. Through this address, the user downloads an alleged application update to the e-wallet application Electrum. The update is in fact malicious content that transfers the contents of the wallet to another wallet. It is estimated that this amounts to more than $ 20 million in damage.

Sharing cookies maps the end users and shares information shared between the advertisers.
The procedure is very common and is loaded in many campaigns, regardless of the creative itself.
Unlike regular attacks, the attack in this case is not related to a single campaign or advertiser - but is served when the SSP advertising platform shares its cookie with other platforms - which generates a widespread attack.
This endangers all advertisements submitted through the same platform.
