Rewterz Threat Alert : ‘Love You’ MalSpam campaign dropping Grandcrab Ransomware, Phorpiex Spambot and Cryptocurrency miner

January 15, 2019

SEVERITY: High

 

 

ANALYSIS SUMMARY

 

 

A massive Malspam campaign using zipped JavaScript (.js) files as malicious email attachments is discovered. The
attachments begin with ‘Love_You_’ indicating the subject matter to be love letters.

 

 

 

 

Behind this LoveYou campaign are hidden malicious hate-worthy entities. The infection traffic includes GandCrab
ransomware, a Monero (XMRig) cryptocurrency miner, and Phorpiex spambot traffic.

Several HTTP requests for additional malware were spotted in the infection traffic, creating multiple copies of same malware on the infected host, which generated Monero (XMRig) cryptocurrency mining traffic as well as the expected post-infection traffic patterns for GandCrab ransomware. The infected host also turned into a spambot for the Phorpiex botnet.

 

 

 

 

GrandCrab dominated the infected host and its file downloader also established itself on a USB thumb drive plugged into the infected host.

 

 

 

 

 

IMPACT

 

 

  • Malware Infection
  • System Compromise
  • Ransomware infection
  • Loss of information
