BianLian Reveals Identity of More Victims, Still Masks Others

BianLian has been proving itself to be a serious threat to the healthcare sector in terms of the number of its attacks. This week, BianLian named Synergy Hematology Oncology Medical Associates in California on their leak site, claiming to have almost 200 GB of data from them. This medical group doesn’t seem to have a website and DataBreaches has not seen any press releases or anything by them about any breach.

BianLian also named Mercy Home in New York on their leak site and claims to have 553 GB of their data. There is no notice on‘s website about any incident.

Although BianLian claims to have leaked the data from both of the above entities, neither download was working as of this morning.

BianLian has also named other medical entities from other countries. They have not yet named all of the U.S. medical entities on their site, including Murfreesboro Medical Clinic in Tennessee or the one DataBreaches suspects is North Shore Medical Labs. BianLian claims to have 60 GB of data from them. DataBreaches has emailed NSML to ask whether they were attacked because there is no notice on their site even though BianLian added the obfuscated listing on April 18. No reply was immediately available.

BianLian also hasn’t publicly named Earlens Corporationalthough one of the listings appears to relate to that firm. They claim to have 2 TB of data from that victim.

AlphV (BlackCat) Starts Leaking Essen Medical Associates

AlphV appears to have started leaking data from Essen Medical Associates on its leak site. Originally added to the site on April 6, the bad actors posted an update this week that says, ‘We gave you time and went to a meeting. Our patience has run out.” They claim to have 2.6 TB of data.

Sadly, as soon as we hit “send” on this post, we’ll probably find yet more breaches in the healthcare sector.
