www.shimaogroup.com Listed by devman Ransomware Group

On September 15, 2025, the ransomware group DevMan added www.shimaogroup.com to its leak site and demanded a $91 million ransom after exfiltrating internal files from the company.

What's Publicly Reported from Reporting

Public reporting indicates that DevMan claims to have stolen internal documents during a ransomware attack on Shimao Group, a large real-estate developer. The leak-site listing appeared on September 15, 2025, and includes samples of the allegedly stolen data. The number of individuals whose personal information may be contained in the files remains unknown. Available reporting describes the exposed material as internal files rather than a structured database of customer records, though such documents frequently contain employee, vendor, or client details including names, contact information, financial records, and identification numbers.

Shimao Group has not yet issued a public statement confirming the breach or the validity of DevMan’s claims. The ransom demand of $91 million is visible on the group’s onion site, which is tracked by ransomware.live.

Why This Matters for You and Your Family

When a company that handles housing contracts, mortgages, or supplier payments is breached, the information inside its files can easily include your address, phone number, bank details, or government ID. Even if you never directly interacted with Shimao Group, vendor or partner lists often pull in data from ordinary families who bought homes, rented property, or worked with related businesses. Once that information leaves the company’s control, it can be sold, posted, or used to fuel further attacks against you. Credential leaks of this type frequently cascade into account takeovers on email, banking, and shopping sites where the same password was reused.

The Doxxing and Identity-Chain Implications

Ransomware operators rarely stop at posting generic files. They map relationships between leaked emails, phone numbers, usernames, and real-world identities to create detailed profiles. A single exposed home address or child’s school record can link to social-media accounts, gaming handles, and family photos. These identity chains allow criminals to harass victims directly, impersonate family members, or launch spear-phishing campaigns that feel personal. Gaming accounts belonging to you or your children are especially vulnerable because they often share the same email or password patterns found in corporate leaks, turning one breach into a pathway for doxxing across platforms.

DevMan’s Publicly Known Track Record

Public reporting attributes DevMan’s emergence to early 2025. The group has targeted organizations across Asia and Europe, with prior victims including manufacturing firms and logistics companies. Their typical playbook begins with initial access through phishing or exploited remote-desktop services, followed by exfiltration of sensitive files before encryption. They then publish samples on their leak site and demand multimillion-dollar payments, threatening to release the full archive if the deadline passes. Exact success rates are difficult to verify, but the group maintains an active presence on dark-web leak portals.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, handles, and real identity so you can see exactly what this leak may have exposed about your household.
• Rotate any password you used at Shimao Group or related vendor sites and enable 2FA through an authenticator app on every account where that password was reused.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information appears it is caught within hours rather than months.
• Cover the household with DoxxScan family coverage that extends to dependents and children’s gaming accounts that often chain back to the same addresses and emails.
• Let remediation specialists handle takedown requests across data brokers and suspicious sites while you focus on securing your own accounts.
