In his blog, Stenberg shows how an attacker replaces a common ASCII character in the code with an almost identical one from the Unicode table. This is not recognizable in the code editor ...

You would typically see fallback characters like question marks when reading foreign languages encoded using ASCII. Currently, Unicode is the gold standard for encoding characters as it includes ...

The new obfuscation technique exploits invisible Unicode characters, specifically Hangul half-width (U+FFA0) and Hangul full-width (U+3164). Each ASCII character in the JavaScript payload is ...

which allows you to 'hide' one byte of data in other Unicode code points.' For example, let's say you want to encode the string 'hello' in ASCII, which is the American character code, as '0x68 ...

The difference can be easily discerned by using any Unicode encoder/decoder, such as the ASCII Smuggler. Rehberger created the tool for converting the invisible range of Unicode characters into ...

Additionally, in the case of HTML Entities, each ‘block’ can have multiple representations, and attackers can use single blocks or block combinations to generate their ASCII/Unicode-based QR ...

The new writer doesn’t serialise JSON the same way as the old one. It doesn’t encode all the higher-ASCII Unicode characters as the older writer did. For example, it won’t encode non-Latin ...

This is where Unicode comes into play. Unicode is similar to ASCII in that it is used to display characters on the screen. Whereas ASCII is limited to 128 or 256 characters however, Unicode ...

In internet communications, ASCII has gradually been superseded by the Unicode standard, which can be used with any language and is compatible with ASCII. However, ASCII is still used for entering ...

curl -X POST 'http://your-dify-instance/v1/workflows/run' \ --header 'Authorization: Bearer your-api-key' \ --header 'Content-Type: application/json' \ --data-raw ...

Security researcher Johann Rehberger explained the mechanics behind ASCII smuggling: “ASCII Smuggling is a novel technique that uses special Unicode characters that mirror ASCII but are actually not ...

"ASCII Smuggling is a novel technique that uses special Unicode characters that mirror ASCII but are actually not visible in the user interface," security researcher Johann Rehberger said. "This means ...
