A new phishing campaign targets Latin American users by sending a phishing email with a ZIP file attachment containing a malicious HTML file posing as an invoice. When the link in the HTML file is opened from a Mexican IP address, a CAPTCHA verification page opens, leading to a malicious RAR file download. This campaign exhibits similarities with previous Horabot malware campaigns in the region. Additionally, there have been malvertising campaigns targeting Microsoft Bing search users with bogus ads for NordVPN, leading to the distribution of remote access trojans and the discovery of fake Java Access Bridge installers that deploy cryptocurrency miners. These incidents demonstrate the ongoing threat of malware infiltration through deceptive tactics.
Based on the meeting notes, the main takeaways are:
1. A new phishing campaign targeting the Latin American region uses a variety of techniques, including malicious email attachments, deceptive domain behavior, and the use of Dropbox to distribute suspicious files.
2. Malvertising campaigns continue to be an effective method for distributing malware, as demonstrated by a recent campaign targeting Microsoft Bing search users with a remote access trojan called SectopRAT.
3. Additional threats include the distribution of a fake Java Access Bridge installer leading to the deployment of a cryptocurrency miner, and the discovery of a Golang malware that uses geolocation checks and screenshots the system before installing a root certificate for communication with a command-and-control server.
These findings highlight the evolving tactics used by threat actors to avoid detection and distribute malware, emphasizing the need for robust cybersecurity measures and vigilance across digital platforms.
