About the Apt73 group

A new ransomware group is said to have emerged in mid-April 2024, under the name 'APT73.' It's worth noting that the group reportedly self-proclaimed as an APT, which stands for 'Advanced Persistent Threat' in the cybersecurity field. According to research, much of the available information about the aforementioned group came from another ransomware group known as LockBit. Source: https://github.com/crocodyli/ThreatActors-TTPs Apt73 has listed 157 victims since April 2024.

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.

Apt73 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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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 .
