SourTrade Malvertising Campaign Secretly Builds Malware in the Browser

SourTrade, a malvertising campaign impersonating cryptocurrency and trading platforms, uses a novel technique to deliver infostealers directly within the browser without traditional file downloads. The malware builds itself in memory during the browsing session, evading common detection methods. Targets receive malicious ads leading to fake versions of legitimate trading sites where the infection occurs.

Why it matters: Trading and cryptocurrency platform users face credential theft and account takeover if they encounter SourTrade ads; security teams should monitor for unusual browser behavior and infostealer activity from users visiting these sectors.
