‘Grandoreiro’ Trojan Targets Global Banking Customers

The Brazilian banking malware known as ‘Grandoreiro’ has expanded its campaign to target customers in Spain, in addition to Brazil and Mexico. The malware is delivered through phishing emails containing a malicious URL that leads to a ZIP file containing a loader. Once executed, the loader downloads a vulnerable application that is exploited to deliver the final payload, which can harvest data from online banking login pages. The rise of Brazilian cybercrime can be attributed to a lack of cybersecurity education and awareness among the general population, as well as the growing middle class and increased online presence in the region.
