The 911 (Nine-One-One) campaign is one deploying a known Mirai variant named Sora. Active since the beginning of April 2020, the campaign has been targeting IoT devices for at least four months. The Sora variant, according to recent reports, exploits remote code exeuction and authentication bypass vulnerabilities in Huawei and Dasan GPON routers, respectively. Another characteristic of this variant is its XOR encryption key, the value 0xDEDEFBAF. Each string in the malware process is decrypted in memory using this key, and is immediately encrypted again to avoid memory-based detection. The name of this botnet campaign is derived from the deployed malware binaries – “911”, with an extension that corresponds to the victim’s architecture. |
