New campaign targeting security researchers

In addition to targeting users via social engineering, we have also observed several cases where researchers have been compromised after visiting the actors’ blog. In each of these cases, the researchers have followed a link on Twitter to a write-up hosted on blog.br0vvnn[.]io, and shortly thereafter, a malicious service was installed on the researcher’s system and an in-memory backdoor would begin beaconing to an actor-owned command and control server. At the time of these visits, the victim systems were running fully patched and up-to-date Windows 10 and Chrome browser versions. At this time we’re unable to confirm the mechanism of compromise, but we welcome any information others might have. Chrome vulnerabilities, including those being exploited in the wild (ITW), are eligible for reward payout under Chrome’s Vulnerability Reward Program. We encourage anyone who discovers a Chrome vulnerability to report that activity via the Chrome VRP submission process.

These actors have used multiple platforms to communicate with potential targets, including Twitter, LinkedIn, Telegram, Discord, Keybase and email. We are providing a list of known accounts and aliases below. If you have communicated with any of these accounts or visited the actors’ blog, we suggest you review your systems for the IOCs provided below. To date, we have only seen these actors targeting Windows systems as a part of this campaign.

If you are concerned that you are being targeted, we recommend that you compartmentalize your research activities using separate physical or virtual machines for general web browsing, interacting with others in the research community, accepting files from third parties and your own security research.
