Spam & Fake Reviews
How Spammers Evade Detection
Attackers simulate real user activity by uploading content scraped from other sites, fooling rules engines, supervised ML, and human reviewers.
Cyber-criminals employ armies of low-cost, on-demand human labor to bypass captchas and create realistic reviews and spam.
Fraudsters incubate fake accounts for months with simulated user activity to evade account-age and activity-based rules.
Fraudsters utilize proxies, VPNs or cloud-hosting services to hide their tracks from IP blacklists and rules-based systems.

What’s Happening with Spam & Fake Reviews
Fraudsters are constantly coming up with new and innovative ways to commit fraud. Today we are taking a look at product listing fraud, a relatively new type of fraud that is a rapidly growing problem for online marketplaces.
A successful spam campaign is one that obtains maximum return-on-investment (ROI) to the spammer. This means that a spam campaign must reach as many end users as possible, must be robust in the face of blacklisting efforts, and must be scalable. This blog post describes some of the recent techniques employed by spammers to distribute malicious URLs on social media platforms as observed by DataVisor.
The DataVisor Online Fraud Report took a look at our base of more than one billion users across 172+ countries in the world. Using this massive amount of data, we were able to identify some of the favorite tools and attack techniques that online criminals from around the globe favor when doing their dirty work.
