Incident analysis

Triple Jump was listed by Ransomhouse ransomware, a group with 159 victims recorded in this database. The listing appeared on the group's leak site on May 16, 2025.

Triple Jump is based in Serbia and operates in the Financial Services sector. Serbia ranks #81 worldwide for ransomware disclosures, with 12 victims in this database.

Sector context. Financial sector organisations are targeted for their access to funds, sensitive financial data, and the reputational damage a public breach can cause. Regulatory requirements also increase recovery costs.

Ransomhouse typically follows a double extortion model: data is exfiltrated from the victim's systems before files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished. The leak site, where this listing appeared, is the lever for the second demand.

Source. Public leak-site disclosures aggregated via the ransomware.live API. The disclosure date is when the listing was published, which can differ from the date of compromise. This site does not publish or link to stolen data. Last updated .
