Frequently Asked Questions

TinyNuke Malware & Threat Intelligence

What is TinyNuke banking malware and who does it target?

TinyNuke is a banking malware that has primarily targeted French entities. It is distributed through campaigns using invoice-themed lures, often impersonating logistics, transportation, or business services organizations. The malware is delivered via URLs in phishing emails that lead to a compressed executable responsible for installing TinyNuke.

How has the activity of TinyNuke campaigns changed over time?

Proofpoint observed a peak in TinyNuke campaigns in 2018, followed by a significant drop in 2019 and 2020. In 2021, there was a resurgence, with three times as many campaigns as the previous two years combined, though the number of messages per campaign was lower. The malware continues to consistently target French organizations.

What tactics do TinyNuke threat actors use to distribute malware?

TinyNuke threat actors use invoice-themed phishing emails that contain URLs leading to compressed executables. These executables install the TinyNuke malware on victims' systems. Some campaigns use Tor for command and control (C2) communications, while others use clear web infrastructure.

What is the significance of TinyNuke's reappearance in 2021?

The reappearance of TinyNuke in 2021, with multiple campaigns and consistent targeting of French organizations, suggests it is a re-emerging threat in the French cybercrime landscape. The use of different lure themes and C2 infrastructures indicates at least two distinct activity sets.

How does TinyNuke use command and control (C2) infrastructure?

One group associated with the original TinyNuke actors uses Tor for C2 communications, a version not publicly available and likely exclusive to these actors. Commodity actors typically use clear web C2 infrastructure.

What are the main delivery methods for TinyNuke malware?

TinyNuke is primarily delivered via phishing emails containing URLs that download compressed executables. These emails often use invoice-themed lures and impersonate legitimate business entities.

TinyNuke Banking Malware Targets French Entities

December 15, 2021

Proofpoint observed dozens of TinyNuke campaigns targeting French entities in 2018. After only observing a handful of TinyNuke campaigns in 2019 and 2020, Proofpoint observed TinyNuke reappear in January 2021 in one campaign distributing around 2,000 emails. Subsequent campaigns appeared in low volumes in May, June, and September. In November, Proofpoint identified multiple TinyNuke campaigns distributing around 2,500 messages and impacting hundreds of customers. In the most recent campaigns, the threat actor uses invoice-themed lures purporting to be logistics, transportation, or business services entities. These messages contain URLs that lead to the download of a compressed executable responsible for installing TinyNuke. Proofpoint first observed TinyNuke in 2017 used as a second-stage payload in a Zeus banking trojan campaign targeting French entities. Its use peaked in 2018 before all but disappearing in Proofpoint data in 2019 and 2020. Proofpoint has observed three times as many TinyNuke campaigns in 2021 as the two previous years combined. But while threat actors have conducted more campaigns this year, they are distributing fewer messages compared to previous years. Though the number of 2021 campaigns is less than 2018, TinyNuke's reappearance and consistent targeting of French organizations is striking, suggesting it is a re-emerging threat in the French cybercrime threat landscape. Proofpoint assesses there are at least two distinct activity sets using TinyNuke based on different lure themes, payload deployment, and command and control (C2) infrastructure. Specifically, one intrusion set associated with the initial TinyNuke actors uses Tor for C2 since 2018, while commodity actors typically leverage clear web C2. Open source reporting suggests the malware version using Tor which Proofpoint has observed with continued regularity is not publicly available, and likely used only by the original TinyNuke threat actors.
