Guess Listed by darkside Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Guess Listed by darkside Ransomware Group (reported February 1, 2021) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
Inside the incident
The only public record of the event is the appearance of Guess on DarkSide’s data-leak site. The group claims to have exfiltrated internal files, but it has not published sample documents or stated how many files were obtained. No independent confirmation of the volume, encryption status, or method of access has been made available. The date the data were allegedly taken and the duration of any unauthorized access are also not known.
Inside darkside
DarkSide is a ransomware operator that conducted campaigns between 2020 and 2021. Its publicly documented pattern involved gaining access to corporate networks, encrypting systems, and copying selected files before demanding payment. The group maintained a leak site where it listed victims that had not paid, presenting the action as a claim rather than verified fact. DarkSide ceased visible operations after infrastructure disruptions in mid-2021.
Who is Guess?
Guess is a global clothing retailer and brand that operates physical stores and online sales channels. Companies of this type routinely process customer account information, order histories, and internal business records. A claimed intrusion at such an organization can affect both the individuals whose records are held and the company’s own operational systems.
What was likely exposed
The listing refers only to “internal files.” The precise categories of data contained in those files have not been disclosed. Retail organizations commonly store customer names, contact details, purchase records, and employee information; whether any of these categories were present in the exfiltrated material remains unconfirmed.
The real-world impact
Individuals whose personal information appears in stolen internal files face the ordinary risks associated with data exposure, such as targeted phishing or account misuse. For the company, the incident adds to the costs of investigation, potential regulatory review, and restoration of systems. Because the scale of the data set is unknown, the extent of these consequences cannot yet be quantified.
Were you affected?
Begin by monitoring statements from Guess for any official notification. Review bank and retail accounts for unusual activity and enable multi-factor authentication where available. Individuals may also submit their email addresses to reputable breach-checking services that aggregate known data exposures to determine whether their information has appeared in public listings.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
