A banking trojan dubbed Mispadu has been linked to multiple spam campaigns targeting countries like Bolivia, Chile, Mexico, Peru, and Portugal with the goal of stealing credentials and delivering other payloads.
Mispadu was first documented by ESET in November 2019, describing its ability to perpetrate monetary and credential theft and act as a backdoor by taking screenshots and capturing keystrokes.
It’s also said to share similarities with other banking trojans targeting the region, like Grandoreiro, Javali, and Lampion. Attack chains involving the Delphi malware leverage email messages urging recipients to open fake overdue invoices, thereby triggering a multi-stage infection process.
The RAR or ZIP archive, when launched, is designed to make use of rogue digital certificates – one which is the Mispadu malware and the other, an AutoIT installer – to decode and execute the trojan by abusing the legitimate certutil command-line utility.
Mispadu is equipped to gather the list of antivirus solutions installed on the compromised host, siphon credentials from Google Chrome and Microsoft Outlook, and facilitate the retrieval of additional malware.
Metabase Q noted that the certutil approach has allowed Mispadu to bypass detection by a wide range of security software and harvest over 90,000 bank account credentials from over 17,500 unique websites.
