A nascent Linux-based mostly botnet named Enemybot has expanded its capabilities to incorporate just lately disclosed security vulnerabilities in its arsenal to focus on web servers, Android gadgets, and written content management techniques (CMS).
“The malware is speedily adopting one-working day vulnerabilities as element of its exploitation abilities,” AT&T Alien Labs claimed in a complex write-up released last week. “Expert services these kinds of as VMware Workspace One particular, Adobe ColdFusion, WordPress, PHP Scriptcase and far more are being focused as perfectly as IoT and Android products.”
To start with disclosed by Securonix in March and later by Fortinet, Enemybot has been connected to a menace actor tracked as Keksec (aka Kek Security, Necro, and FreakOut), with early assaults focusing on routers from Seowon Intech, D-Url, and iRZ.
Enemybot, which is able of carrying out DDoS assaults, draws its origins from many other botnets like Mirai, Qbot, Zbot, Gafgyt, and LolFMe. An assessment of the hottest variant reveals that it can be designed up of four various components –
- A Python module to down load dependencies and compile the malware for various OS architectures
- The core botnet portion
- An obfuscation phase intended to encode and decode the malware’s strings, and
- A command-and-regulate operation to acquire attack instructions and fetch further payloads
Also included is a new scanner operate which is engineered to look for random IP addresses connected with public-experiencing belongings for opportunity vulnerabilities, even though also having into account new bugs inside of days of them remaining publicly disclosed.
“In situation an Android device is connected by USB, or Android emulator working on the device, EnemyBot will attempt to infect it by executing [a] shell command,” the scientists stated, pointing to a new “adb_infect” functionality. ADB refers to Android Debug Bridge, a command-line utility used to connect with an Android gadget.
In addition to the Log4Shell vulnerabilities that came to gentle in December 2021, this features lately patched flaws in Razer Sila routers (no CVE), VMware Workspace A single Access (CVE-2022-22954), and F5 Significant-IP (CVE-2022-1388) as nicely as weaknesses in WordPress plugins like Movie Synchro PDF.
Other weaponized security shortcomings are beneath –
- CVE-2022-22947 (CVSS rating: 10.) – A code injection vulnerability in Spring Cloud Gateway
- CVE-2021-4039 (CVSS rating: 9.8) – A command injection vulnerability in the web interface of the Zyxel
- CVE-2022-25075 (CVSS rating: 9.8) – A command injection vulnerability in TOTOLink A3000RU wireless router
- CVE-2021-36356 (CVSS rating: 9.8) – A remote code execution vulnerability in KRAMER VIAware
- CVE-2021-35064 (CVSS score: 9.8) – A privilege escalation and command execution vulnerability in Kramer VIAWare
- CVE-2020-7961 (CVSS rating: 9.8) – A remote code execution vulnerability in Liferay Portal
What is actually far more, the botnet’s source code has been shared on GitHub, making it extensively available to other menace actors. “I assume no obligation for any damages brought on by this program,” the project’s README file reads. “This is posted underneath Apache license and is also viewed as artwork.”
“Keksec’s Enemybot seems to be just setting up to unfold, having said that due to the authors’ fast updates, this botnet has the likely to come to be a significant risk for IoT devices and web servers,” the researchers claimed.
“This signifies that the Keksec team is well resourced and that the team has created the malware to get benefit of vulnerabilities before they are patched, hence escalating the velocity and scale at which it can distribute.”
