HelloKitty is not a new ransomware group it can be tracked as early as 2020, mainly targeting Windows systems.Hive uses all tools available in the extortion toolset to create pressure on the victim, including the date of initial compromise, countdown, the date the leak was actually disclosed on their site, and even the option to share the disclosed leak on social media. Since then, Hive has impacted 28 organizations that are now listed on the group’s extortion site, including a European airline company and three U.S.-based organizations. Hive Ransomware is double-extortion ransomware that started operations in June.We have observed initial ransom demands ranging from $50,000 to $75,000. This ransomware also has an extortion site, which claims to have impacted six organizations in the following countries: the U.S., the U.K., the U.A.E., Belgium, Spain and Lebanon.

Like many of its competitors, AvosLocker offers technical support to help victims recover after they’ve been attacked with encryption software that the group claims is “fail-proof,” has low detection rates and is capable of handling large files.

AvosLocker was observed promoting its RaaS program and looking for affiliates on dark web discussion forums and other forums.

AvosLocker is ransomware as a service (RaaS) that started operations in late June, using a blue beetle logo to identify itself in communications with victims and “press releases” aimed at recruiting new affiliates.

During our operations, we have observed four emerging ransomware groups that are currently affecting organizations and show signs of having the potential to become more prevalent in the future: We monitor the activity of existing groups, search for dark web leak sites and fresh onion sites, identify up-and-coming players and study tactics, techniques and procedures. As part of Unit 42’s commitment to stop ransomware attacks, we conduct ransomware hunting operations to ensure our customers are protected against new and evolving ransomware variants.
