Salve, Habr! Iterum, loquimur de recentioribus versionibus malware e categoriis Ransomware. HILDACRYPT novum pretium est, membrum familiae Hildae mense Augusto 2019 repertum, nomine Netflix, quod programmatum distribuere solebat. Hodie novimus notas technicas huius virus redemptionis renovationis.
In prima versione Hildae redemptionis, ligamen ad unum missae in Youtube series viverra in litteris redemptis continebatur. HILDACRYPT fingit legitimum XAMPP institutorem, facilem institutionem Apache distributionis quae MariaDB, PHP et Perl includit. Eodem tempore cryptocker lima nomen aliud habet - xamp. Praeterea fasciculus redemptionis electronicam subscriptionem non habet.
Static analysis
Vectigationis vasculum in PE32 .NET lima scriptum pro Fenestra MS. Magnitudo eius 135 bytes est. Utrumque codicem principale programmatis et programma defensoris in C# scripta sunt. Secundum compilationem notae ac temporis notae binarii die 168 Septembris MMXIX creatus est.
Secundum Deprehendere Facilem, pretium est scrinium utentes Confuser et ConfuserEx, sed hi obfuscatores idem sunt qui prius, solum ConfuserEx est successor Confuser, ideo eorum signaturae similes sunt.
HILDACRYPT quidem cum ConfuserEx fasciculatum est.

impetum vector
Verisimile est, pretium in una programmandi interreti situm inventum est, errans in programmate legitimo XAMPP.
Tota catena contagionis videri potest .
Obfuscation
chordae redemptionis in encrypted forma conditae sunt. Cum deductae sunt, HILDACRYPT decryptas illis utentes Base64 et AES-256-CBC.
occasum
Imprimis, pretium redemptionis in %AppDataRoaming% folder in quo GUID (Globally Unique Identifier) modulus passim generatur. Addendo fasciculum vespertilionis huic loco, virus redemptionis immittit utens cmd.exe:
cmd.exe /c JKfgkgj3hjgfhjka.bat & exit
Tunc incipit exsequi batch scriptor ut inactivandi ratio features vel officia.
Scriptum longum continet iussionum indices qui codices umbram destruunt, solutiones SQL servers, tergum et antivirum inactivare.
Exempli gratia, Tergum Acronis operas infeliciter prohibere conatur. Praeterea systemata tergum impugnat et solutiones antivirorum ex venditoribus sequentibus: Veeam, Sophos, Kaspersky, McAfee et alios.
