Vega Stealer, a variation of August Stealer works by snatching identity details and credit card information stored in victims' Chrome and Firefox browsers.
Afterwards, like any other house breaker, Vega sniffs around to try to find anything else of value in the computers saved or sensitive documents.
Why is it so Dangerous?
Vega Stealer is a phishing scam, which targets the sellers not the buyers, unlike a 'Malvertising' campaign where cyber criminals deliver malware through online ads, Vega are doing it through emails, in low – volume email campaigns, it has so far had a limited effect.
Some emails were sent to individuals, others to larger distribution lists including "info@' and 'Publicaffairs@" which allowed the email to hit a slightly wider audience. The messages contained a malicious attachment called "brief.doc. holding macros that delivered the Vega Stealer payload.
Using Subject lines such as “Item return” and “Our company need online store from a scratch”, Vega has crept its way into systems via a pretty standardized phishing campaign. The victims, then click on the malicious macros in the document to enable Vega Stealer.
Once the victim enables the macros, Vega Stealer starts going to work on the system.
Phishing campaign? Low volume email list? What exactly is so worrying, you may ask? Surely just don't click on the link, or authorize it if you click by mistake and everyone's happy? Surely, a limited number of victims in a scam that has already been discovered means that the chance of it spreading is considerably lowered.
Not quite, the researchers at Proofpoint believe that this macro, now available for sale on the dark net is being applied to multiple and much more harmful conditions – for example through the Emotet Banking Trojan.
If the payload could be effectively delivered by a simple phishing scam, we could be in a world of trouble.
Proofpoint researchers stated “The document macro utilized in this campaign is a commodity macro that we believe is for sale and used by multiple actors. We attribute this campaign to the same actor with medium confidence.”
Although Proofpoint can only state it with 'medium confidence', we can state with full confidence that Vega Stealer should be putting more than just the Online Retail market on full alert.
From Financial Institutions to Governmental Departments, this Stealer spreading across the Dark Net and fast, has to be stopped in its tracks.
