The mechanism to remove the available Shadow Copies was changed to using Component Object Model objects that execute Windows Management Instrumentation queries. This sample was detected in a large, unnamed manufacturing company where attackers had network access and were gathering information for two weeks. They have compromised the company’s domain controller and used it to distribute ransomware to all devices within the organization through Group Policy Object.

For backups, follow the 3-2-1 rule: 3 copies, 2 devices, and 1 stored in a secure location. Data loss is manageable through segmentation, off-line storage, encrypting data at rest, and limiting the storage of personal and sensitive data.<br/> <b>MITRE ATT&amp;CK:</b> <a href="https://ui.threatstream.com/ttp/2402531" target="_blank">[MITRE ATT&amp;CK] Data Encrypted for Impact - T1486</a> | <a href="https://ui.threatstream.com/ttp/3905074" target="_blank">[MITRE ATT&amp;CK] Phishing - T1566</a> | <a href="https://ui.threatstream.com/ttp/947231" target="_blank">[MITRE ATT&amp;CK] Valid Accounts - T1078</a> | <a href="https://ui.threatstream.com/ttp/947138" target="_blank">[MITRE ATT&amp;CK] Exploit Public-Facing Application - T1190</a> | <a href="https://ui.threatstream.com/ttp/947077" target="_blank">[MITRE ATT&amp;CK] Windows Management Instrumentation - T1047</a> | <a href="https://ui.threatstream.com/ttp/947127" target="_blank">[MITRE ATT&amp;CK] Scheduled Task - T1053</a> | <a href="https://ui.threatstream.com/ttp/3906161" target="_blank">[MITRE ATT&amp;CK] Command and Scripting Interpreter - T1059</a> | <a href="https://ui.threatstream.com/ttp/3905040" target="_blank">[MITRE ATT&amp;CK] Create or Modify System Process - T1543</a> | <a href="https://ui.threatstream.com/ttp/3905768" target="_blank">[MITRE ATT&amp;CK] Boot or Logon Autostart Execution - T1547</a> | <a href="https://ui.threatstream.com/ttp/3905764" target="_blank">[MITRE ATT&amp;CK] Hijack Execution Flow - T1574</a> | <a href="https://ui.threatstream.com/ttp/947233" target="_blank">[MITRE ATT&amp;CK] Exploitation for Privilege Escalation - T1068</a> | <a href="https://ui.threatstream.com/ttp/947141" target="_blank">[MITRE ATT&amp;CK] Masquerading - T1036</a> | <a href="https://ui.threatstream.com/ttp/947142" target="_blank">[MITRE ATT&amp;CK] Process Injection - T1055</a> | <a href="https://ui.threatstream.com/ttp/947194" target="_blank">[MITRE ATT&amp;CK] Indicator Removal on Host - T1070</a> | <a href="https://ui.threatstream.com/ttp/947166" target="_blank">[MITRE ATT&amp;CK] Modify Registry - T1112</a> | <a href="https://ui.threatstream.com/ttp/2402543" target="_blank">[MITRE ATT&amp;CK] Virtualization/Sandbox Evasion - T1497</a> | <a href="https://ui.threatstream.com/ttp/3905778" target="_blank">[MITRE ATT&amp;CK] Impair Defenses - T1562</a> | <a href="https://ui.threatstream.com/ttp/3905348" target="_blank">[MITRE ATT&amp;CK] OS Credential Dumping - T1003</a> | <a href="https://ui.threatstream.com/ttp/947276" target="_blank">[MITRE ATT&amp;CK] Network Service Scanning - T1046</a> | <a href="https://ui.threatstream.com/ttp/2402537" target="_blank">[MITRE ATT&amp;CK] Domain Trust Discovery - T1482</a> | <a href="https://ui.threatstream.com/ttp/947162" target="_blank">[MITRE ATT&amp;CK] Remote Services - T1021</a> | <a href="https://ui.threatstream.com/ttp/947110" target="_blank">[MITRE ATT&amp;CK] Taint Shared Content - T1080</a> | <a href="https://ui.threatstream.com/ttp/3904544" target="_blank">[MITRE ATT&amp;CK] Lateral Tool Transfer - T1570</a> | <a href="https://ui.threatstream.com/ttp/947193" target="_blank">[MITRE ATT&amp;CK] Automated Exfiltration - T1020</a> | <a href="https://ui.threatstream.com/ttp/3904494" target="_blank">[MITRE ATT&amp;CK] Exfiltration Over C2 Channel - T1041</a> | <a href="https://ui.threatstream.com/ttp/947224" target="_blank">[MITRE ATT&amp;CK] Exfiltration Over Alternative Protocol - T1048</a> | <a href="https://ui.threatstream.com/ttp/3905082" target="_blank">[MITRE ATT&amp;CK] Exfiltration Over Web Service - T1567</a> | <a href="https://ui.threatstream.com/ttp/947139" target="_blank">[MITRE ATT&amp;CK] Remote Access Tools - T1219</a> | <a href="https://ui.threatstream.com/ttp/3297598" target="_blank">[MITRE ATT&amp;CK] Account Access Removal - T1531</a><br/> <b>Tags:</b> actor:Vice Society, malware-type:Ransomware, target-industry:Education, target-industry:Healthcare, detection:HelloKitty, file-type:ELF, Linux, detection:Zeppelin, Windows, PrintNightmare, CVE-2021-1675, CVE-2021-34527, target-country:US, target-country:UK</p> </div> <div class="trending-threat-article"> <h3><a href="https://blog.sucuri.net/2022/12/infected-wordpress-plugins-redirect-to-push-notification-scam.html" target="_blank">Infected WordPress Plugins Redirect to Push Notification Scam</a></h3> <p>(published: December 6, 2022)</p> <p>A new malicious campaign targeting WordPress websites adds a listener to the whole page’s onclick event causing fraudulent redirects whenever a site visitor clicks on any link. Sucuri researchers discovered that the malicious script avoids detection by using obfuscation followed by unusual hexadecimal encoding of the binary string. Additionally this script detects open Developer Tools using multiple alternative methods, including checks for the following functions: checkByImageMethod, checkDevByScreenResize, detectDevByKeyboard, checkByFirebugMethod, and checkByProfileMethod.<br/> <b>Analyst Comment:</b> Website owners should pay attention to the feedback from website visitors as some malicious activity can be seen only by those who match certain profiling (such as the absence of dev tools).

All three were disguising their malicious Javascript as Google code (Google Tag Manager or Google Analytics). Common tactics included code obfuscation, and referrer fingerprinting. Group X was able to mass-inject their code by exploiting a free, third-party JavaScript library that was discontinued in December 2014. They re-registered the abandoned domain name and used it to serve their skimming scripts via the URL that the old library was hosted at.<br/> <b>Analyst Comment:</b> Site administrators should be aware of supply-chain dependencies and remove ones that are unsupported and/or abandoned. Keep their systems updated and secure the administrator panel with two-factor authentication or other access restrictions. If your site was infected, perform a core file integrity check, query for any files containing the same injection, and check any recently modified or added files.
