ATCK Ransomware is a malicious software variant that encrypts files on infected computers, rendering them inaccessible to users. This ransomware is part of the Dharma family, known for its damaging capabilities and widespread impact. This article provides an in-depth look at how ATCK ransomware operates, including its infection methods, encryption process, ransom note details, and potential recovery options. Upon infection, ATCK ransomware encrypts files and modifies their filenames significantly. It appends the victim's unique ID, the attacker's email address, and the .ATCK extension to each encrypted file's name. For instance, a file named example.jpg would be renamed to example.jpg.id-{random-ID}.[attackattack@tutamail.com].ATCK after encryption. This renaming scheme not only signifies the file has been encrypted but also provides the victim with contact information for the ransom negotiation. ATCK ransomware delivers its ransom demands through two primary methods: a text file named info.txt and a pop-up window. Both notes inform the victim that their files have been encrypted and offer a way to restore them through contact with the attackers via provided email addresses (attackattack@tutamail.com or attackattack@cock.li). The ransom notes emphasize that attempting to decrypt files with third-party software could lead to permanent data loss, and they offer free decryption of a few files as proof that they can reverse the encryption.

IRIS Ransomware is a malicious software that encrypts files on a victim's computer, demanding a ransom for their decryption. It is identified as a variant of the Chaos ransomware family. This crypto-virus is particularly harmful as it not only locks files but also threatens to leak stolen sensitive data if the ransom is not paid. Upon infection, IRIS Ransomware begins encrypting files across various formats, including documents, images, and databases. It appends a unique four-character extension to each file it encrypts, making the filenames appear with random characters, such as 1.jpg.p67l or 2.docx.2n8h. After encryption, IRIS changes the desktop wallpaper and drops a ransom note named read_it.txt in the affected directories. This note informs victims that their files have been encrypted and demands a ransom of $350, payable in Monero (XMR), a cryptocurrency. The note also warns that the victim’s sensitive data, including browsing history and personal details, has been stolen, implying that formatting the device will not prevent the attackers from leaking this information.
