For years, the hacking unit inside Russia’s GRU army intelligence company generally known as Sandworm has carried out a few of the worst cyberattacks in historical past—blackouts, fake ransomware, data-destroying worms—from behind a fastidiously maintained veil of anonymity. But after half a decade of the spy company’s botched operations, blown cowl tales, and worldwide indictments, maybe it is no shock that pulling the masks off the person main that extremely harmful hacking group at the moment reveals a well-known face.

The commander of Sandworm, the infamous division of the company’s hacking forces accountable for most of the GRU’s most aggressive campaigns of cyberwar and sabotage, is now an official named Evgenii Serebriakov, in accordance with sources from a western intelligence service who spoke to WIRED on the situation of anonymity. If that title rings a bell, it might be as a result of Serebriakov was indicted, together with six different GRU brokers, after being caught within the midst of a close-range cyberespionage operation in the Netherlands in 2018 that focused the Organization for the Prohibition of Chemical Weapons within the Hague.

In that foiled operation, Dutch regulation enforcement did not simply establish and arrest Serebriakov and his workforce, who had been a part of a unique GRU unit generally called Fancy Bear or APT28. They additionally seized Serebriakov’s backpack filled with technical tools, in addition to his laptop computer and different hacking units in his workforce’s rental automotive. As a outcome, Dutch and US investigators had been capable of piece collectively Serebriakov’s travels and previous operations stretching again years and, given his newer function, now know in uncommon element the profession historical past of a rising GRU official.

According to the intelligence service sources, Serebriakov was positioned accountable for Sandworm within the spring of 2022 after serving as deputy commander of APT28, and now holds the rank of colonel. Christo Grozev, the lead Russia-focused investigator for open-source intelligence outlet Bellingcat, has additionally famous Serebriakov’s rise: Around 2020, Grozev says, Serebriakov started receiving telephone calls from GRU generals who, within the company’s strict hierarchy, solely converse to higher-level officers. Grozev, who says he purchased the telephone information from a Russian black market supply, says he additionally noticed the GRU agent’s quantity seem within the telephone information of one other highly effective army unit centered on counterintelligence. “I realized he must be in a command position,” says Grozev. “He can’t just be a regular hacker anymore.”

The indisputable fact that Serebriakov seems to have attained that place regardless of having been beforehand recognized and indicted within the failed Netherlands operation means that he should have vital worth to the GRU—that he is “apparently too good to dump,” Grozev provides.

Serebriakov’s new place main Sandworm—formally GRU Unit 74455, but additionally identified by the nicknames Voodoo Bear or Iridium—places him accountable for a gaggle of hackers who’re maybe the world’s most prolific practitioners of cyberwar. (They’ve additionally dabbled in espionage and disinformation campaigns.) Since 2015, Sandworm has led the Russian authorities’s unprecedented marketing campaign of cyberattacks on Ukraine: It penetrated electrical utilities in Western Ukraine and Kyiv to cause the first- and second-ever blackouts triggered by hackers, focused Ukrainian authorities companies, banks, and media with numerous data-destructive malware operations. In 2017, Sandworm launched NotPetya, a piece of self-replicating code that spread to networks worldwide and inflicted a record $10 billion in damage. Sandworm then went on to sabotage the 2018 Winter Olympics in Korea and assault TV broadcasters within the nation of Georgia in 2019, a surprising file of reckless hacking.
