Proofpoint was the first one to observe this malware. It said that Vega Stealer is a variant of the famous August Stealer. This information stealer was first identified when a low-volume mail campaign was spotted by Proofpoint using subject lines which had the phrases “Item return” and “Our company need online store from scratch.” This email campaign was directed at lists of people and individuals. However, all the potential victims were placed in the same target group, and in each case, the email included a document containing malicious macros which the receivers had to enable.
