13,000 MikroTik Routers Hijacked by Botnet for Malspam and Cyberattacks

13,000 MikroTik Routers Hijacked by Botnet for Malspam and Cyberattacks

Jan 21, 2025 Email Security / Botnet
A global network of about 13,000 hijacked Mikrotik routers has been employed as a botnet to propagate malware via spam campaigns, the latest addition to a list of botnets powered by MikroTik devices. The activity "take[s] advantage of misconfigured DNS records to pass email protection techniques," Infoblox security researcher David Brunsdon said in a technical report published last week. "This botnet uses a global network of Mikrotik routers to send malicious emails that are designed to appear to come from legitimate domains." The DNS security company, which has codenamed the campaign Mikro Typo , said its analysis sprang forth from the discovery of a malspam campaign in late November 2024 that leveraged freight invoice-related lures to entice recipients into launching a ZIP archive payload. The ZIP file contains an obfuscated JavaScript file, which is then responsible for running a PowerShell script designed to initiate an outbound connection to a command-a...
Critical MikroTik RouterOS Vulnerability Exposes Over Half a Million Devices to Hacking

Critical MikroTik RouterOS Vulnerability Exposes Over Half a Million Devices to Hacking

Jul 26, 2023 Network Security / Vulnerability
A severe privilege escalation issue impacting MikroTik RouterOS could be weaponized by remote malicious actors to execute arbitrary code and seize full control of vulnerable devices. Cataloged as  CVE-2023-30799  (CVSS score: 9.1), the shortcoming is expected to put approximately 500,000 and 900,000 RouterOS systems at risk of exploitation via their web and/or Winbox interfaces, respectively, VulnCheck disclosed in a Tuesday report. "CVE-2023-30799 does require authentication," security researcher Jacob Baines  said . "In fact, the vulnerability itself is a simple privilege escalation from admin to 'super-admin' which results in access to an arbitrary function. Acquiring credentials to RouterOS systems is easier than one might expect." This is because the Mikrotik RouterOS operating system does not offer any protection against password brute-force attacks and ships with a well-known default "admin" user, with its password being an empty string...
Majority of Browser Extensions Can Access Sensitive Enterprise Data, New Report Finds

Majority of Browser Extensions Can Access Sensitive Enterprise Data, New Report Finds

Apr 15, 2025Data Privacy / Enterprise Security
Everybody knows browser extensions are embedded into nearly every user's daily workflow, from spell checkers to GenAI tools. What most IT and security people don't know is that browser extensions' excessive permissions are a growing risk to organizations. LayerX today announced the release of the Enterprise Browser Extension Security Report 2025 , This report is the first and only report to merge public extension marketplace statistics with real-world enterprise usage telemetry. By doing so, it sheds light on one of the most underestimated threat surfaces in modern cybersecurity: browser extensions. The report reveals several findings that IT and security leaders will find interesting, as they build their plans for H2 2025. This includes information and analysis on how many extensions have risky permissions, which kinds of permissions are given, if extension developers are to be trusted, and more. Below, we bring key statistics from the report. Highlights from the Enterprise Browse...
TrickBot Malware Abusing MikroTik Routers as Proxies for Command-and-Control

TrickBot Malware Abusing MikroTik Routers as Proxies for Command-and-Control

Mar 17, 2022
Microsoft on Wednesday detailed a previously undiscovered technique put to use by the TrickBot malware that involves using compromised Internet of Things (IoT) devices as a go-between for establishing communications with the command-and-control (C2) servers. "By using MikroTik routers as proxy servers for its C2 servers and redirecting the traffic through non-standard ports, TrickBot adds another persistence layer that helps malicious IPs evade detection by standard security systems," Microsoft's Defender for IoT Research Team and Threat Intelligence Center (MSTIC)  said . TrickBot, which emerged as a banking trojan in 2016, has evolved into a sophisticated and persistent threat, with its modular architecture enabling it to adapt its tactics to suit different networks, environments, and devices as well as offer access-as-a-service for next-stage payloads like Conti ransomware. The expansion to TrickBot's capabilities comes amid reports of its  infrastructure goin...

Over 300,000 MikroTik Devices Found Vulnerable to Remote Hacking Bugs

Over 300,000 MikroTik Devices Found Vulnerable to Remote Hacking Bugs

Dec 09, 2021
At least 300,000 IP addresses associated with MikroTik devices have been found vulnerable to multiple remotely exploitable security vulnerabilities that have since been patched by the popular supplier of routers and wireless ISP devices. The most affected devices are located in China, Brazil, Russia, Italy, Indonesia, with the U.S. coming in at number eight, cybersecurity firm Eclypsium said in a report shared with The Hacker News. "These devices are both powerful, [and] often highly vulnerable," the researchers  noted . "This has made MikroTik devices a favorite among threat actors who have commandeered the devices for everything from DDoS attacks, command-and-control (aka 'C2'), traffic tunneling, and more." MikroTik devices are an enticing target not least because there are more than two million of them deployed worldwide, posing a huge attack surface that can be leveraged by threat actors to mount an array of intrusions. Indeed, earlier this Septem...
