The campaign is assessed to be ongoing since May 2026.<\/p>\n<p>\u00abSpecifically, on job search websites, after reviewing a candidate&#8217;s resume, the attackers contact a potential victim \u2013 typically a system administrator or IT specialist \u2013 on behalf of an IT company (such as ATLAS Business Group),\u00bb CERT-UA <a href=\"https:\/\/cert.gov.ua\/article\/6318863\" target=\"_blank\">said<\/a>. <\/p>\n<p>Although initial communications take place via built-in online chat, the conversation subsequently shifts to messaging apps like Telegram, where a preliminary chat takes place with a purported HR manager who claims to be in charge of the candidate screening process for Sopra Steria Bulgaria, a legitimate European-based consulting and software company.<\/p>\n<div class=\"dog_two clear\">\n<div class=\"cf\"><a href=\"https:\/\/thehackernews.uk\/zero-trust-claude-d\" rel=\"nofollow noopener sponsored\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" class=\"lazyload\" alt=\"Cybersecurity\" src=\"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEj8iAp2j8rqTq6aptj6yiYHC-B73UxnWI2NQMt0azp6OVLq9JkO8cpYokLWa8t_IKqrHKPsaM5D_lQ9Ip7kZTi3at4oYfzN1m1b_T4b6MuzBWtmlhdLcQ0nZHicD94rliREFDRewsKBQCTYrAAVNzYKj84_0EZskDUxvkc972s9fYAqcQGEQjVZTc0cr7TB\/s728-e100\/ThreatLocker-d.jpg\" width=\"729\" height=\"91\"\/><\/a><\/div>\n<\/div>\n<p>As part of the chat, the agency said general work-related questions and the candidates&#8217; English language proficiency are discussed, after which they are invited to join a Zoom videoconference call.<\/p>\n<p><a name=\"more\"\/><\/p>\n<p>While the meeting does take place as expected with an English-speaking man who appears to be between 30 and 35 years old, it&#8217;s unclear whether the person showing up in the interview was a genuine participant or a synthetic persona generated using artificial intelligence (AI).<\/p>\n<p>In tandem, additional instructions for a technical interview are sent via an email.

None of these projects are available for download.<\/p>\n<p>\u00abThe essence of this trick is that the attackers&#8217; VPN client was compiled from the WireGuard source code with a number of modifications,\u00bb CERT-UA explained. \u00abSpecifically, support for the non-standard &#8216;SymmetricKey&#8217; option has been added to the configuration processing mechanism; its value contains BASE64-encoded data for AES-256-GCM: a nonce, ciphertext, and an authentication tag.\u00bb<\/p>\n<p>\u00abA 32-byte value obtained by decoding &#8216;PrivateKey&#8217; is used as the AES-256 key.
