Threat actors target email addresses, as they provide a way to access personal and confidential information.
Emails often hold valuable data such as financials, login credentials, and personal messages.
The attackers could start different kinds of cyber-attacks and propagate malware via compromised email addresses.
Cybersecurity researcher Will (@BushidoToken) recently discovered that threat actors from UAC-0050 (aka DaVinci Group) have been actively targeting and hacking thousands of email addresses to malspam campaigns.
UAC-0050 Hacked Thousands
CERT-UA reported on 22 Feb 2024 linking UAC-0050 to “The DaVinci Group,” a Russian-speaking mercenary org tied to Russian law enforcement.
UAC-0050 has been targeting Ukrainian organizations since the 2022 Russian invasion.
Besides this, it’s been attributed to 15 malspam campaigns, acting as initial access brokers for threat groups like Sandworm and Fancy Bear.

CERT-UA shared artifacts like file paths and domains tied to UAC-0050 on various occasions by providing insight into their activities.
The DaVinci Group has been actively launching malspam attacks against Ukrainian targets since at least 2017.
They have targeted government ministries, local authorities, the military, and civilians with tens of thousands of harvested email addresses.
