More than 20 Brazilian government websites were hijacked and turned into malware delivery channels in an active PhantomEnigma <\/b>campaign uncovered by ANY.RUN<\/a>, a leading provider of interactive malware analysis and threat intelligence solutions.<\/p>\n

The investigation revealed previously undocumented backdoor behavior, hidden infrastructure relationships, and multiple attack arms behind a campaign putting banks and public agencies at risk.<\/p>\n

By connecting hundreds of seemingly unrelated sandbox sessions, ANY.RUN researchers exposed the operation\u2019s broader scope and showed how trusted .gov.br links and authenticated emails helped the activity remain hidden.<\/p>\n

Trusted Government Infrastructure Became the Lure<\/h2>\n

The attack began with fake police-themed documents presented as official \u201cOf\u00edcio Pol\u00edcia Civil\u201d or \u201cProcura\u00e7\u00e3o Digital\u201d notices. Some contained QR codes, while others directed recipients to links designed to look like legitimate government resources.<\/p>\n\n\n\n\n

In several cases, the emails were sent through compromised mailboxes and passed SPF, DKIM, and DMARC checks. That gave the messages a stronger appearance of legitimacy than ordinary spoofed phishing emails.<\/p>\n

<\/p>\n

Victims were then redirected through compromised .gov.br hosts or police-themed lookalike domains before reaching the malicious installer. The government systems were used as trusted delivery infrastructure, not necessarily as the final targets of the campaign.<\/p>\n

Observed Government Hosts<\/h3>\n

Among the compromised systems observed during the investigation were timon.ma.gov[.]br, loginam.sesp.es.gov[.]br (state public security), aplicacao.cbm.mt.gov[.]br (fire department), prodoc.ap.gov[.]br, and others.<\/p>\n\n\n\n\n

These legitimate municipal, public-security, and judicial portals were used at different stages of the delivery chain. Several also appeared across more than one PhantomEnigma attack arm, helping researchers connect activity that initially looked unrelated.<\/p>\n

PhantomEnigma\u2019s Evolution: Two Paths to Harder Detection<\/h2>\n\n\n\n\n
\"\"<\/a><\/td>\n<\/tr>\n
Timeline of PhantomEnigma\u2019s malisious activity<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The timeline shows one operation evolving along two main paths:<\/p>\n

Delivery:<\/strong> PhantomEnigma moved from banking-focused activity in 2025 to abusing compromised .gov.br websites and email accounts in 2026. This gave the campaign a more trusted route to victims without confirming a new target group.<\/p>\n

Arsenal:<\/strong> The malware evolved from a browser-extension banker into a modular Inno\/Node.js backdoor capable of executing JavaScript and delivering additional payloads.<\/p>\n

For security teams, this combination creates a serious visibility gap. Trusted infrastructure reduces suspicion, modular payloads can change after infection, and rotating C2 domains quickly make static blocklists outdated. Behavioral analysis and continuous threat hunting provide more reliable coverage as the campaign evolves.<\/p>\n

Once a victim engaged with the lure, the campaign moved through a multi-stage infection chain:<\/p>\n

    \n
  1. Phishing email:<\/strong> A fake police-themed or official-document lure reaches the victim.<\/li>\n
  2. Trusted infrastructure:<\/strong> The link redirects through a compromised government host or police-themed lookalike domain.<\/li>\n
  3. Malicious installer:<\/strong> An Inno Setup, MSI, or another installer starts the infection.<\/li>\n
  4. Patched Electron application:<\/strong> Legitimate software loads a malicious index.js backdoor.<\/li>\n
  5. Backdoor activation:<\/strong> The malware collects system data, establishes persistence, and connects to rotating C2 infrastructure.<\/li>\n
  6. Second-stage delivery:<\/strong> The backdoor executes JavaScript or delivers stealers, loaders, RMM software, and other malware.<\/li>\n
  7. Business impact:<\/strong> The infection can lead to credential compromise, unauthorized access, fraud, data exposure, and operational disruption.<\/li>\n<\/ol>\n

    What Researchers Found Inside PhantomEnigma\u2019s Backdoor<\/h2>\n

    The sandbox sessions exposed more than a simple downloader. Hidden inside a patched Boostnote and other applications was a modular index.js backdoor built to identify infected machines, maintain access, and deliver different payloads on demand.<\/p>\n

    Once activated, the backdoor could:<\/p>\n
