pixiewps

개요 Pixiewps 는 C로 작성된 도구로, 일부 소프트웨어 구현의 낮거나 존재하지 않는 엔트로피를 악용하여 WPS PIN을 오프라인 무차별 대입 하는 데 사용됩니다. 이른바 "pixie-dust 공격"은 2014년 여름 Dominique Bongard에 의해 발견되었습니다. 교육 목적으로만 사용됩니다. Reaver나 Bully와 같은 도구에 구현된 기존의 온라인 무차별 대입 공격과 달리, 이 방법은 취약한 경우 대상에 따라 PIN을 몇 초 또는 몇 분 만에 얻을 수 있습니다. 버전 1.4부터는 일부 장치에 대해 완전한 수동...

Shelltropy

Shelltropy 予測可能であればあるほど、検出されにくくなる シャノン符号化による低エントロピーに基づいた悪意のあるシェルコードを隠蔽する手法です。 エントロピーとは、データ（ここではシェルコード）内のランダム性の尺度です。エントロピーが高いほど、データはよりランダムになります。シャノンエントロピーは0から8の間の結果を生成するアルゴリズムで、8はデータにパターンがなく非常にランダムであることを示し、0はデータがパターンに従っていることを示します。 注: 私の研究の詳細な説明と、シンプルなバニラシェルコードインジェクションのPoCについては、ブログ記事をご覧ください。 セットアップ...

claude-awm: can you scrub a SynthID text watermark by editing the text? Yes, but only one family of attack works, and it isn't the one everyone assumes. Unicode variation selectors category Mn, U+FE00 to U+FE0F and U+E0100 to U+E01EF drive the detector below threshold and stay there. Every other...

CVE-2026-66372 Predictable Seed in Pseudo-Random Number Generator (PRNG) in Digital Watchdog VMAX DVR and NVR Product Lineups

The affected products use insufficiently random values, which allows web session tokens to be predictable, bounding token entropy to the seed space...

Fedora 43 : perl-Dancer2 (2026-d0bededb87)

The remote Fedora 43 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-d0bededb87 advisory. Dancer2 gnrates sessions id from low-entropy sources if Crypt::URandom and Math::Random::ISAAC::XS are not present. With this update, they are always there...

Astra Linux – Vulnerability in mbedtls

In Arm Mbed TLS before version 2.19.0, and Arm Mbed Crypto before version 2.0.0, when deterministic ECDSA is enabled, an RNG with insufficient entropy is used for blinding. This may allow an attacker to recover a private key through side-channel attacks if a victim signs the same message multiple...
