Attack summary

Severity: critical — Confirmed exfiltration of 693 GB including proprietary source code, critical infrastructure backups, and customer databases from regulated telecom sector. Claims include data from major telecom operators (Vodafone, Etiya, Bouygues, Freedom Mobile, Turk Telekom) and sensitive security firm (Veriskop). This represents significant risk to telecom supply chain integrity and customer data at scale.

Barracuda claims to have exfiltrated 693 gigabytes of data from i2i Systems over the course of a week, including 44 gigabytes of complete source code across multiple projects. The group asserts access to databases, server backups, and customer data from telecom partners including Vodafone, Etiya, Bouygues, Freedom Mobile, Turk Telekom, and the security firm Veriskop, though the specific contents and verification of these claims are not independently confirmed in the post.

Data the group says was taken

AI dossier — extracted from the leak post

Source code repositories (Caplan, DataGov, DDR, DFE, Kangal, SDD, smartdq, CopyCat, and others)
Linux server backups and snapshots (Veriskop, partner infrastructure)
Database backups (Veriskop, partner databases)
Customer database (Turk Telekom)
Infrastructure configuration files
Development and production database snapshots

The group's post references roughly 15 named backup files listed proof files.

What the group claims

This is one of the most poorly secured companies we have ever encountered. Over the course of a week, we analyzed the infrastructure and moved freely across their network. The infrastructure lacked proper security configurations, and the IT department showed a complete disregard for the data. As a result of the attack, 693 gigabytes of data were exfiltrated. We downloaded the complete source code for the following projects: Caplan DataGov-Dev-Docker DDR DDR-Veriskop DFE-Dev Kangal-Dev SDD-DEV-DOCKER SDD-MAIN commonprojects.zip Copycat.zip CopycatLive.zip datacat.war datagov.war Kangal-Dev.zip Kangal-Master.zip [email protected] smartdq.war The volume of exfiltrated source code totaled 44 gigabytes. The data includes a full snapshot of the latest releases from the development repository. i2i-systems has a direct connection to the information security company Veriskop; therefore, this breach directly affects them as well. In addition, i2i-systems engaged in joint projects with partners such as Vodafone, Etiya, Bouygues, Freedom Mobile, and others; this is evidenced by the Linux servers located within the i2i-systems infrastructure: 1864654005 backup_Veriskop-SQA1.local_2026-08-31_203808.tar.gz 3292962897 copycat2019.i2isystems.local_critical_backup_2026-08-31_19-30-29.tar.gz 18422354 critical_backup_bouygues_fcbs_batch2.local_20260830_221815.tar.gz 2231188487 etiya-mobile-test-01.local_backup_20260831_213207.tar.gz 20546323810 freedom-mobile1-critical-vault.tar.gz 1050673952 freedom-mobile2-secrets-20260830-232814.tar.gz 721661 maya-redhat7-9_2026-08-30_233036.tar.gz 22966288270 ol8-10-innobi_full_backup_20260831_022640.tar.gz 529695763 veriskop-db-critical-backup-2026-08-31_234418.tar.gz 13012999372 veriskop-fiziksel-yedek-20260831023535.tar.gz 309528511 veriskop-oracle-critical-backup-2026-08-31_203340.tar.gz 633604141 veriskop-rhel-7.local_critical_backup.tar.gz 4878999722 Veriskoptest01.local_backup_20260831_213236.tar.gz 238487575 Veriskoptest02.local_critical_backup_20260831_213052.tar.gz 33936543608 veriskoptest03_critical_backup_2026-08-31.tar.gz We have extracted absolutely all critical data from these infrastructure Linux systems and created a snapshot of the databases.

Disclosure context

About Barracuda

Barracuda is a ransomware group first observed in August 2026 with an apparent primary motivation of financial gain, though limited public reporting exists given its recent emergence and relatively small confirmed victim count of four organizations. The group's country of origin and potential affiliations with established threat actors or ransomware-as-a-service ecosystems have not been publicly confirmed by CISA, the FBI, Mandiant, or other reputable security research organizations at this time. Based on available victim telemetry, Barracuda has demonstrated a targeting pattern focused on manufacturing, healthcare, and technology sector organizations, with victim distribution concentrated across China, the United States, and South Korea, suggesting either opportunistic targeting within these regions or deliberate selection based on perceived ransom-paying capacity; specific details regarding initial access vectors, tooling, encryption methodology, or data exfiltration practices remain undocumented in open-source reporting. No major high-profile campaigns, record ransom demands, or law enforcement actions against the group have been publicly documented, which is consistent with the group's nascent operational timeline and low confirmed victim count. Given its first observation date of August 2026 and the absence of substantial public intelligence, Barracuda should be considered an emerging and closely monitored threat whose full capabilities, affiliations, and operational scope remain to be established through continued tracking by the security research community. The group has been linked to 17 public disclosures across our corpus. First observed on a leak site on August 6, 2026; most recent post September 13, 2026. The operation is currently active.

If your organisation is affected

A listing by Barracuda means i2i-systems appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
Monitor for the data appearing on Barracuda's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
