ESET stated its most likely hypothesis is that Turla and Gamaredon were working together. “Given that both groups belong to the Russian FSB (though in 2 various Centers), Gamaredon offered access to Turla operators so that they might release commands on a particular device to reboot Kazuar, and release Kazuar v2 on some others,” the business stated.

Friday’s post kept in mind that Gamaredon has actually been seen working together with other hack groups formerly, particularly in 2020 with a group ESET tracks under the name InvisiMole.

In February, ESET stated, business scientists found 4 unique Gamaredon-Turla co-compromises in Ukraine. On all of the devices, Gamaredon released a vast array of tools, consisting of those tracked under the names PteroLNK, PteroStew, PteroOdd, PteroEffigy, and PteroGraphin. Turla, for its part, set up variation 3 of its exclusive malware Kazuar.

ESET software application set up on among the jeopardized gadgets observed Turla releasing commands through the Gamaredon implants.

“PteroGraphin was utilized to reboot Kazuar, potentially after Kazuar crashed or was not introduced instantly,” ESET stated. “Thus, PteroGraphin was most likely utilized as a healing approach by Turla. This is the very first time that we have actually had the ability to connect these 2 groups together by means of technical indications (see First chain: Chain: Restart of Kazuar v3.”

In April and once again in June, ESET stated it discovered Kazuar v2 installers being released by Gamaredon malware. In all the cases, ESET software application was set up after the compromises, so it wasn’t possible to recuperate the payloads. The company stated it thinks an active partnership in between the groups is the most likely description.

“All those aspects, and the truth that Gamaredon is jeopardizing hundreds if not countless makers, recommend that Turla is interested just in particular devices, most likely ones including extremely delicate intelligence,” ESET hypothesized.
