Previous threat activity from the group targeted various users in Russia and the United States. Identified in the CERT-UA alert is a RAR file archive that translates to “the preservation of video recordings of criminal actions of the army of the Russian Federation.rar.” The malicious archive when open provides a lure document, DLL file with a .dat file extension and a batch file. Currently, it is unknown what Scarab/UAC-0026 threat objectives are.

Industry: Telecommunications | Level: Strategic | Sources: DataCenterDynamics & Forbes

Reported from Data Center Dynamics, outages were identified to Ukraine’s telecoms operator, Ukrtelecom and internet service provider (ISP), Triolan. An investigation of the activity by Doug Madory, the director of internet analysis at Kentik, identified the disruption in service from Ukrtelecom resulted in an approximate, 40 minute outage period. The impact to Triolan is more severe as the ISP, is experiencing an excess of 12 hours for its an outage period. The attack against Triolan has also been reported by Forbes, identifying from sources within the company that the cause of the outage was due to a “cyberattack.” The cyberattack against Triolan appears to have started on March 9th, 2022 when outages were first experienced, with the identified issue shared as “attackers reset the settings to the factory level [with impact to] key nodes of the network.” Partial service has been restored as Triolan restored “70% of those nodes in Kyiv, Kharkiv, Dnipro, Poltava, Odesa, Rivne and Zaporizhia.” The cyberattack against Triolan is not the first as a post on the company’s Telegram page reveals a hack on February 24 as well.

Industry: N/A | Level: Strategic | Source: BleepingComputer

Initially discovered by ESET researchers and reported by BleepingComputer, a new data-destroying malware named CaddyWiper is attacking Ukrainian organizations. Shared from ESET’s Twitter, “ESET telemetry shows that it was seen on a few dozen systems in a limited number of organizations.” Interestingly the malware conducts a check on the host to validate if it’s a domain controller and if so, the data on the domain controller will not be affected. ESET hypothesizes this exclusion is to ensure access is retained by the attacker. Analysis of the malware identified it was compiled on Monday, March 14th, 2022 at 07:19:32 UTC. While the malware does not share “significant code similarity” with prior wipers, CaddyWipper’s deployment is similar to HermaticWiper as ESET tweet states, “similarly to HermeticWiper deployments, we observed CaddyWiper being deployed via GPO, indicating the attackers had prior control of the target’s network beforehand.”

Proofpoint research provides an update for activity since November 2021, involving Chinese APT group TA416, initiating targeted campaigns against European Diplomatic entities. An increase in activity has been observed since the invasion with Russia in Ukraine has taken place.  A new technique was identified in the group’s phishing campaigns.  Initiallythe threat group utilizes web bugs to profile victims to provide a “sign of life,” indicating to the attackers the victim is active and can be enticed into opening malicious emails. Phishing emails have then been observed to be leveraging “email marketing service SMTP2Go, which allows users to alter the envelope sender field while using a unique sender address generated by the service field while using a unique sender address generated by the service.” The abuse of the SMTP2Go service has enabled the group to impersonate different European organizations. When sending the malicious phishing emails, the threat actor provides a DropBox link containing the malware executable, PlugX in a zip file. Upon execution, the malware establishes persistence through DLL Search Order hijacking using PE file potplayermini.exe associated with a public media player and downloads additional payloads.
