Malicious use of reCaptcha walls in 1,28, 000 emails: Report

Barracuda Networks, a provider for cloud-enabled security solutions, on May 1 announced the April Threat spotlight.

The researchers have noticed the frequent use of fake Microsoft reCaptcha walls in phishing campaigns to block URL scanning services from accessing the actual content of phishing pages, the organization mentioned in its official release.

The organization stated that the battle between cybersecurity and cybercrime is never-ending where criminals continue to find new techniques to evade detection. Recaptcha walls are commonly used by legitimate companies to deter bots from scraping content. Considering that the end-users are familiar with being asked to solve a reCaptcha and prove they aren’t a robot, malicious use of a real reCaptcha wall also lends more credibility to the phishing site, making users more likely to be tricked.
