Rewterz Threat Alert – Malspam Campaign Delivering Malicious Files Using Compromised Windstream Email Addresses

Rewterz Threat Advisory – CVE-2019-1029 – Microsoft Lync Server 2010 / 2013 Denial of Service Vulnerability
June 14, 2019

Rewterz Threat Alert – “Love You” Malspam Phishing Campaign Reemerged

June 14, 2019

Severity

Medium

Analysis Summary

A malspam email campaign that has emails with subject lines about love letters and had a zip attachment with a name starting with “Love_You_”. The zip file, when uncompressed, contained a JavaScript file that, upon execution, performed several HTTP requests to download additional malicious executables. These executables were a Monero cryptocurrency miner, Phorpiex spambot malware, and GandCrab ransomware. The Phorpiex spambot malware caused the victim host to be joined to a botnet and begin emailing out copies of the malicious zip file to additional targets. Meanwhile the victim host was infected with ransomware and leveraged to mine crypto-currency.
