OLX uses machine learning models to detect new fraud schemes
The OLX platform has a number of tools to ensure security and detect fraudulent schemes; due to systematic work, it has been possible to reduce the number of fraud cases by 90% over the past three years, the OLX press service told Interfax-Ukraine.
In response to an information request, it is noted that OLX specialists are constantly improving algorithms and analyzing atypical behavior on the platform, using machine learning models to quickly detect new fraud schemes. Moderators and category specialists check content daily, respond to complaints and cooperate with law enforcement agencies to investigate offenses. Thanks to these measures, the number of fraud cases on OLX has decreased by 90% over the past three years, and phishing transactions through OLX Delivery make up only 0.03% of the total number of transactions.
OLX also said all users have the opportunity to communicate regarding goods or services in a special chat. This opportunity – to conduct correspondence directly on the platform without going to other resources – was introduced almost immediately after the launch of the service itself. In addition to communication, the chat also performs a protective function. The service chat is under the responsibility and control of OLX, it also contains advice on how to conclude safe agreements and not expose yourself to danger.
OLX algorithms operating in the chat allow you to identify potentially dangerous links or viruses that may be fraudulent. This is why attackers often ask in correspondence to transfer communication to another messenger that will not block dangerous links. The OLX service chat allows communication between the seller and the buyer in the most secure environment. If one of the parties tries to send a message with dangerous content, such as a phishing link, the message will not be delivered to the chat, and the sender will be blocked.
During the post-moderation of ads, OLX involves its trusted business clients to help identify fake and irrelevant ads. This process is streamlined using the Work by the Rules program. For this service, users receive a bonus to promote their high-quality published ads.
The OLX platform implements a number of internal and partner projects, including Trust & Safety, aimed at raising user awareness of fraud and social engineering.
