8Base attacks CETEC Ingénierie

8Base claimed a ransomware attack against CETEC Ingénierie. The group has exfiltrated diverse types of data, including invoices, receipts, accounting documents, personal data, certificates, employment contracts, an extensive amount of confidential information, confidentiality agreements, and personal files. CETEC Ingénierie is an engineering firm that carries out project management missions and multidisciplinary technical design office in the field of construction. The 8Base ransomware gang first emerged in March of 2022 and has quickly become one of the most active groups today, having displayed a "massive spike in activity" in the first half of 2023. About half of the 8Base targets are in the business services, manufacturing, and construction sectors. The sophistication of the operation suggests they are an offshoot of experienced RaaS operators - most likely Ransomhouse, a data extortion group that first emerged in December of 2021 and was quite active in late 2022 and early 2023. Other researchers see a connection to the leaked Babuk builder. Like most groups today, 8Base engages in data exfiltration for double extortion and employs advanced security evasion techniques including modifying Windows Defender Firewall for bypass.‍ 8Base quickly ascended the ranks of active ransomware operators with a high volume of attacks in late spring and throughout the summer of 2023, making them one of the most active groups.‍ It is unclear how much 8Base typically demands for a ransom. 8Base does not appear to have its own signature ransomware strain or maintain an RaaS for recruiting affiliate participation openly, but it is assessed they may service a group of vetted affiliate attackers privately. Like RansomHouse, they appear to use a variety of ransomware payloads and loaders in their attacks, most prevalently customized Phobos with SmokeLoader. Attacks also include wiping of Volume Shadow Copies (VSS) to prevent rollback of the encryption. 8Base does not appear to be targeting Linux systems, maintaining a focus on Windows targets. 8Base tends to target organizations who provide Business Services as well as those in the Manufacturing, Financial, and Information Technology sectors.‍ 8Base does not appear to maintain a RaaS program, appearing to be opportunistic in their choice of victims, with a focus on “name and shame” via their leaks site to compel payment of the ransom demand.
