CowerSnail — Windows Backdoor from the Creators of SambaCry Linux Malware

Jul 27, 2017
Last month, we reported about a group of hackers exploiting SambaCry —a 7-year-old critical remote code execution vulnerability in Samba networking software—to hack Linux computers and install malware to mine cryptocurrencies. The same group of hackers is now targeting Windows machines with a new backdoor, which is a QT-based re-compiled version of the same malware used to target Linux. Dubbed CowerSnail , detected by security researchers at Kaspersky Labs as Backdoor.Win32.CowerSnail, is a fully-featured windows backdoor that allows its creators to remotely execute any commands on the infected systems. Wondering how these two separate campaigns are connected? Interestingly, the CowerSnail backdoor uses the same command and control (C&C) server as the malware that was used to infect Linux machines to mine cryptocurrency last month by exploiting the then-recently exposed SambaCry vulnerability. Common C&C Server Location — cl.ezreal.space:20480 SambaCry vulnerabi...
New Linux Malware Exploits SambaCry Flaw to Silently Backdoor NAS Devices

New Linux Malware Exploits SambaCry Flaw to Silently Backdoor NAS Devices

Jul 19, 2017
Remember SambaCry ? Almost two months ago, we reported about a 7-year-old critical remote code execution vulnerability in Samba networking software, allowing a hacker to remotely take full control of a vulnerable Linux and Unix machines. We dubbed the vulnerability as SambaCry, because of its similarities to the Windows SMB vulnerability exploited by the WannaCry ransomware that wreaked havoc across the world over two months ago. Despite being patched in late May, the vulnerability is currently being leveraged by a new piece of malware to target the Internet of Things (IoT) devices, particularly Network Attached Storage (NAS) appliances, researchers at Trend Micro warned . For those unfamiliar: Samba is open-source software (re-implementation of SMB/CIFS networking protocol), which offers Linux/Unix servers with Windows-based file and print services and runs on the majority of operating systems, including Linux, UNIX, IBM System 390, and OpenVMS. Shortly after the publi...
The Identities Behind AI Agents: A Deep Dive Into AI and NHI

The Identities Behind AI Agents: A Deep Dive Into AI and NHI

Apr 10, 2025AI Security / Enterprise Security
AI agents have rapidly evolved from experimental technology to essential business tools. The OWASP framework explicitly recognizes that Non-Human Identities play a key role in agentic AI security. Their analysis highlights how these autonomous software entities can make decisions, chain complex actions together, and operate continuously without human intervention. They're no longer just tools, but an integral and significant part of your organization's workforce. Consider this reality: Today's AI agents can analyze customer data, generate reports, manage system resources, and even deploy code, all without a human clicking a single button. This shift represents both tremendous opportunity and unprecedented risk. AI Agents are only as secure as their NHIs Here's what security leaders are not necessarily considering: AI agents don't operate in isolation . To function, they need access to data, systems, and resources. This highly privileged, often overlooked acces...
7-Year-Old Samba Flaw Lets Hackers Access Thousands of Linux PCs Remotely

7-Year-Old Samba Flaw Lets Hackers Access Thousands of Linux PCs Remotely

May 25, 2017
A 7-year-old critical remote code execution vulnerability has been discovered in Samba networking software that could allow a remote attacker to take control of an affected Linux and Unix machines. Samba is open-source software (re-implementation of SMB networking protocol) that runs on the majority of operating systems available today, including Windows, Linux, UNIX, IBM System 390, and OpenVMS. Samba allows non-Windows operating systems, like GNU/Linux or Mac OS X, to share network shared folders, files, and printers with Windows operating system. The newly discovered remote code execution vulnerability ( CVE-2017-7494 ) affects all versions newer than Samba 3.5.0 that was released on March 1, 2010. "All versions of Samba from 3.5.0 onwards are vulnerable to a remote code execution vulnerability, allowing a malicious client to upload a shared library to a writable share, and then cause the server to load and execute it," Samba wrote in an advisory published Wed...
