🥇HILDACRYPT: Loaʻa ka ransomware hou i nā ʻōnaehana backup a me nā hoʻonā antivirus

Aloha, Habr! Eia hou, ke kamaʻilio nei mākou e pili ana i nā mana hou o ka malware mai ka māhele Ransomware. ʻO HILDACRYPT kahi ransomware hou, he lālā o ka ʻohana Hilda i ʻike ʻia ma ʻAukake 2019, i kapa ʻia ma hope o ka pahu kiʻi Netflix i hoʻohana ʻia e kahele ʻana i ka polokalamu. I kēia lā ke kamaʻāina nei mākou i nā hiʻohiʻona ʻenehana o kēia hōʻano hou ransomware virus.

Ma ka mana mua o Hilda ransomware, he loulou i kahi i kau ʻia ma Youtube kiʻi wikiō Aia i loko o ka leka ho'ōla. Hoʻopili ʻo HILDACRYPT ma ke ʻano he mea hoʻonohonoho XAMPP kūpono, kahi mahele Apache maʻalahi e hoʻokomo pū me MariaDB, PHP, a me Perl. I ka manawa like, he inoa faila ʻē aʻe ka cryptolocker - xamp. Eia kekahi, ʻaʻohe pūlima uila i ka faila ransomware.

ʻIkepili paʻa

Aia ka ransomware ma kahi faila PE32 .NET i kākau ʻia no MS Windows. ʻO 135 bytes kona nui. Ua kākau ʻia ka code program nui a me ka code program defense ma C#. Wahi a ka lā hōʻuluʻulu a me ka hōʻailona manawa, ua hana ʻia ka binary ma Kepakemapa 168, 14.

Wahi a Detect It Easy, ua hoʻopaʻa ʻia ka ransomware me ka hoʻohana ʻana i Confuser a me ConfuserEx, akā ua like kēia mau obfuscators e like me ka mea ma mua, ʻo ConfuserEx wale nō ka mea i pani iā Confuser, no laila ua like kā lākou mau inoa code.

Hoʻopili ʻia ʻo HILDACRYPT me ConfuserEx.

Hoʻouka kaua

ʻO ka mea maʻamau, ua ʻike ʻia ka ransomware ma kekahi o nā pūnaewele hoʻonohonoho pūnaewele, e hoʻohālikelike ana me he polokalamu XAMPP kūpono.

Hiki ke ʻike ʻia ke kaulahao holoʻokoʻa o ka maʻi ma app.any.run sandbox.

Obfuscation

Mālama ʻia nā kaula ransomware ma ke ʻano i hoʻopili ʻia. Ke hoʻokuʻu ʻia, hoʻokaʻawale ʻo HILDACRYPT iā lākou me ka hoʻohana ʻana iā Base64 a me AES-256-CBC.

Kāu Mau Koho Paʻamau

ʻO ka mea mua, hana ka ransomware i kahi waihona ma %AppDataRoaming% kahi i hoʻokumu ʻia ai ka GUID (Globally Unique Identifier) ʻano. Ma ka hoʻohui ʻana i kahi faila bat i kēia wahi, hoʻomaka ka ransomware virus me ka hoʻohana ʻana i ka cmd.exe:

A laila hoʻomaka ia e hoʻokō i kahi hōʻailona batch e hoʻopau i nā hiʻohiʻona ʻōnaehana a i ʻole nā lawelawe.

Aia i loko o ka palapala kahi papa inoa lōʻihi o nā kauoha e hoʻopau i nā kope o ke aka, hoʻopau i ka server SQL, backup a me nā hoʻonā antivirus.

No ka laʻana, hoʻāʻo ʻole ʻo ia e kāpae i nā lawelawe ʻo Acronis Backup. Eia kekahi, hoʻouka ia i nā ʻōnaehana backup a me nā ʻōnaehana antivirus mai nā mea kūʻai aku: Veeam, Sophos, Kaspersky, McAfee a me nā mea ʻē aʻe.
