Researchers linked the 8Base ransomware group to the Phobos ransomware-as-a-service ecosystem and mapped a broad infrastructure used to support its campaigns. Analysis tied 8Base activity since at least mid-2023 to custom Phobos branding such as the .8base extension, a sharp rise in victim postings, and supporting malware including SmokeLoader and SystemBC, the latter used as a SOCKS5 proxy to mask command-and-control traffic. A DNS-focused investigation started from 63 indicators tied to an 8Base Phobos campaign and expanded that set to 404 potentially connected web properties, revealing recurring use of .pro domains, many registrations created in 2023, and repeated hosting and geolocation links to Germany, including infrastructure associated with Hetzner Online.

8 events from the most recent confirmed update back to the earliest known activity.
In April 2024, S-RM identified a Faust operator using a new onion-based leak site called Space Bears to extort a victim. S-RM assessed this as evidence of Phobos affiliates pivoting toward data theft and double extortion.
On February 29, 2024, CISA released a joint cybersecurity advisory on Phobos ransomware. The advisory highlighted current operations and, according to S-RM, signaled Phobos' move into double extortion, including data exfiltration using tools such as MegaSync.
Intel-Ops reports that since December 2023, 8Base has regularly posted multiple victims in a single day. This marked a notable increase in the group's public victim disclosure tempo.
In September 2023, a verbose Laravel error page on 8Base's Tor leak site exposed the clearnet IP address 95.216.51[.]74 and referenced a private GitLab path tied to JCube Group, prompting reporting that linked Moldovan developer Andrei Kolev to at least some of the site's code. After the reporter contacted Kolev, the site stopped showing the verbose error and began returning a 405 Method Not Allowed response to the same request.
In June 2023, a Faust team message to an S-RM client said, "Your data is safe. We have not, and never do take data." This reflects Phobos affiliates' earlier encryption-focused posture before later double-extortion activity.
Multiple references state that 8Base began ramping up or was active from mid-2023, using Phobos ransomware in attacks. Intel-Ops says 8Base operations and victim volume increased in June 2023.
Acronis reports that an 8Base-associated Tor data leak site was launched in March 2022, indicating the group's extortion infrastructure was in place well before its public surge in 2023. The report says the operators later used the site to publish leaked victim data from the prior year's operations.
S-RM states that the Phobos ransomware operation has been active since May 2018. The group is described as a ransomware-as-a-service operation and a variant of the Dharma ransomware locker.
