ThreatAI Analysis

Compiled from this incident record and the threat intelligence profile for Trigona. Figures and technique mappings are quoted from the source data, not inferred.

About the Trigona group

According to PCrisk, Trigona is ransomware that encrypts files and appends the ._locked extension to filenames. Also, it drops the how_to_decrypt.hta file that opens a ransom note. An example of how Trigona renames files: it renames 1.jpg to 1.jpg._locked, 2.png to 2.png._locked, and so forth.It embeds the encrypted decryption key, the campaign ID, and the victim ID in the encrypted files. Trigona has listed 49 victims since April 2023.

How Trigona is documented to operate

Exploit Public-Facing Application T1190 Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network. The weakness in the system can be a software bug, a temporary glitch, or a misconfiguration. Exploited applications are often websites/web servers, but can also include databases (like SQL), standard services (like SMB or SSH), network device administration and management protocols (like SNMP and Smart Install), and any other system with Internet-accessible open sockets. On ESXi infrastructure, adversaries may exploit exposed OpenSLP services; they may alternatively exploit exposed VMware vCenter servers.

MITRE ATT&CK reference โ†’
Deobfuscate/Decode Files or Information T1140 Stealth

Adversaries may use Obfuscated Files or Information to hide artifacts of an intrusion from analysis. They may require separate mechanisms to decode or deobfuscate that information depending on how they intend to use it. Methods for doing that include built-in functionality of malware or by using utilities present on the system. One such example is the use of certutil to decode a remote access tool portable executable file that has been hidden inside a certificate file. Another example is using the Windows <codecopy /b</code or <codetype</code command to reassemble binary fragments into a malicious payload.

Incident Analysis

Dinamic Oil was targeted by Trigona ransomware, one of the most active ransomware groups in our database with 19 confirmed victims globally. The attack was disclosed on February 28, 2024, when Dinamic Oil appeared on the group's dark web leak site.

Dinamic Oil is based in Italy , operating in the Manufacturing sector. Italy ranks #5 globally for ransomware attacks, with 557 victims in our database.

Sector context: Manufacturing companies are frequently targeted because production downtime directly translates to financial loss. Ransomware operators exploit this time-sensitivity to demand higher ransoms and faster payment.

Trigona typically employs a double extortion model: first exfiltrating sensitive data from the victim's systems, then deploying ransomware to encrypt files. Victims face two simultaneous threats โ€” paying to restore access and paying to prevent publication of stolen data. The group's leak site publishes victim names and exfiltrated data as leverage.

Data source: This incident record is sourced from public ransomware group leak site disclosures aggregated via the ransomware.live API. Disclosure date reflects when the victim was published on the leak site, which may differ from the initial date of compromise. This platform does not publish or link to stolen data.

How can organisations protect against Trigona attacks?

To defend against Trigona and similar threat actors, organisations should: maintain regular offline backups tested for restoration; implement network segmentation to limit lateral movement; deploy multi-factor authentication on all remote access; use endpoint detection and response (EDR) tools; conduct regular phishing and security awareness training; and monitor threat intelligence feeds for indicators of compromise (IOCs) associated with active groups.
