Three Nigerians suspected of being part of a cybercrime group that targeted tens of thousands of victims around the world have been arrested today in Lagos, Nigeria’s capital, Interpol reported. From a report: In a report disclosing its involvement in the investigation, security firm Group-IB said the three suspects are members of a cybercrime group they have been tracking since 2019 and which they have been tracking under the codename of TMT. Group-IB said the group primarily operated by sending out mass email spam campaigns containing files laced with malware. To send their email spam, the group used the Gammadyne Mailer and Turbo-Mailer email automation tools and then relied on MailChimp to track if a recipient victim opened their messages. The file attachments were laced with various strains of malware that granted hackers access to infected computers from where they focused on stealing credentials from browsers, email, and FTP clients.
