Brazilian Police Bypassed 'View Once' on WhatsApp; Dutch Intel Warns Russian State Hackers Are Already Inside Your Signal Chats

Post date: March 13, 2026 · Discovered: April 17, 2026 · 3 posts, 0 comments

Brazilian Federal Police allegedly extracted data from 'view once' WhatsApp messages, proving robust technical methods can defeat ephemeral messaging security. Simultaneously, Dutch intelligence confirms Russian state hackers are conducting global, large-scale campaigns specifically targeting Signal and WhatsApp accounts.

The discussion splits between two stark realities. One side cites the Brazilian PF's successful post-mortem technical bypass of anti-forensics features. Conversely, others emphasize preventative warnings from Dutch sources, detailing ongoing social engineering attacks that steal account access credentials, rather than exploiting platform flaws.

The clear message is compromise at the account level, not the app level. The consensus points to two actionable threats: real-world forensic capability that defeats privacy settings, and active, person-based attacks (phishing/social engineering) that bypass technical safeguards entirely. Users must assume their accounts are compromised.
