Duque Saldarriaga Listed by arcusmedia Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On 3 June 2024, the marketing firm Duque Saldarriaga was listed by the arcusmedia ransomware group. Public reporting states that the group claims to have exfiltrated internal files during a ransomware attack. The number of people affected remains unknown, and further details about the timing or full scope of the incident have not been disclosed.

For individuals or organisations that have dealt with Duque Saldarriaga, the listing raises the practical question of whether any of their information was among the material the group claims to hold. Because the exact contents and volume of data are unconfirmed, the situation calls for careful attention rather than alarm.

Breaking down the breach

The only confirmed public facts are the date of the listing—3 June 2024—and the attribution to arcusmedia. The group’s leak-site entry asserts that internal files were taken in a ransomware attack. No independent confirmation of the claim has been published, and the number of people affected is listed as unknown. Method of initial access, duration of the intrusion, encryption status of systems, and any ransom demand remain undisclosed. In short, the public record consists of a single listing and a brief description of the data type involved; everything else is unconfirmed.

Inside arcusmedia

Arcusmedia is a ransomware operation that follows the now-common double-extortion model: encrypting systems while also copying data and threatening to publish it if payment is not made. Groups of this type typically maintain dedicated leak sites where they post victim names and sample files to increase pressure. Public reporting on arcusmedia’s prior activity shows a pattern of targeting mid-sized organisations across various sectors and of advertising stolen data when negotiations stall. In the present case the group claims to have taken internal files from Duque Saldarriaga; that assertion should be treated as an unverified claim until corroborated by the victim or independent investigators.

Who is Duque Saldarriaga?

Duque Saldarriaga describes itself as a marketing company. Firms in this sector routinely handle client contact lists, campaign materials, internal strategy documents, employee records, and financial or contractual information related to advertising work. A breach at such an organisation can therefore affect both the company’s own staff and the businesses or individuals whose data appear in marketing databases. Because marketing agencies often serve as intermediaries that store data belonging to multiple clients, the potential reach of any compromise extends beyond the firm’s immediate workforce.

What data was at risk

The only data type named in public reporting is “internal files exfiltrated in ransomware attack.” No further breakdown—such as whether those files contained personal identifiers, financial records, or client lists—has been released. Organisations of this kind typically hold employee personal data, client contact information, project files, and business correspondence. Until the precise contents are confirmed, it is accurate only to say that internal files are claimed to have been taken and that the exact nature of any personal or commercial data remains unconfirmed.

What's at stake

If personal information was among the internal files, affected individuals could face risks of phishing, social-engineering attempts, or identity misuse once the data is circulated. For Duque Saldarriaga itself, the incident may disrupt operations, damage client trust, and create regulatory or contractual obligations to notify parties whose data were involved. Because the scale is unknown, the practical impact ranges from limited internal inconvenience to broader exposure of third-party information. The absence of confirmed numbers means any assessment of harm must remain provisional.

Were you affected?

Anyone who has worked with or supplied data to Duque Saldarriaga should treat the listing as a prompt for basic precautions rather than proof of personal compromise. Concrete first steps include:

• Reviewing recent account activity for unfamiliar logins or password-reset requests.
• Enabling multi-factor authentication on email and financial accounts where it is not already active.
• Treating unsolicited messages that reference the company or marketing work with heightened caution.
• Monitoring credit or identity-protection services if personal identifiers were ever shared with the firm.

Readers can also run a free exposure scan of their email address to check whether that address has already appeared in known breach data sets. Public detail on this incident remains limited; further clarity will depend on official statements from Duque Saldarriaga or independent verification of the arcusmedia claims.
