Disclosure context

About ALP-001

ALP-001 is an emerging ransomware group first observed in March 2026 with limited documented activity, having targeted only five known victims to date with a focus on financially motivated cybercrime. Due to the group's recent emergence and low victim count, their country of origin, operational structure, and potential affiliations remain unknown with no public documentation from major security firms or law enforcement agencies regarding their organizational structure. Their attack methodology, encryption techniques, and initial access vectors have not been publicly analyzed or reported by reputable security researchers, though their targeting pattern suggests a preference for technology and manufacturing sectors across developed nations including the United States, Japan, China, France, and Italy. No notable campaigns, high-profile incidents, or significant ransoms have been publicly documented for this group, and no law enforcement actions have been reported against ALP-001. The group's current operational status remains unclear due to limited public intelligence and their recent emergence in the threat landscape. The group has been linked to 17 public disclosures across our corpus. First observed on a leak site on March 21, 2026; most recent post April 8, 2026. The operation is currently active.
