Tonto Team Exploits Anti-Malware File to Attack South Korean Institutions

April 28, 2023
Malware / Cyber Threat

Recent attacks by the China-aligned threat actor known as the Tonto Team have targeted South Korean education, construction, diplomatic, and political institutions. The AhnLab Security Emergency Response Center (ASEC) reported that the group is utilizing a file associated with anti-malware products to carry out their malicious activities. Active since at least 2009, Tonto Team has a history of attacks across various sectors in Asia and Eastern Europe. Earlier this year, they were linked to an unsuccessful phishing attempt on the cybersecurity firm Group-IB. According to ASEC, the attack begins with a Microsoft Compiled HTML Help (.CHM) file that runs a binary to side-load a malicious DLL (slc.dll) and deploy the ReVBShell backdoor, an open-source VBScript tool also used by another Chinese threat actor, Tick.

How Vulnerabilities Lead to Breaches: Analyzing 5 Real-World Examples

📅 April 28, 2025
Cloud Security / Vulnerability

Not all security vulnerabilities pose a high risk on their own, but in the hands of skilled attackers, even minor weaknesses can escalate into significant breaches. This article highlights five real vulnerabilities identified by Intruder’s bug-hunting team, illustrating how attackers exploit overlooked flaws to create serious security incidents.

  1. Compromising AWS Credentials via Redirects
    Server-Side Request Forgery (SSRF) is a prevalent vulnerability that can have severe consequences, particularly in cloud environments. If a web application retrieves resources from user-provided URLs, it’s crucial to prevent attackers from manipulating requests to access unauthorized resources. During our evaluation of a home-moving application hosted on AWS, our team explored common SSRF bypass techniques. The attack unfolded as follows: the application sent a webhook request to the attacker’s server, which responded with a 302 redirect to AWS’s metadata service. The application followed the redirect and logged the response, inadvertently exposing sensitive metadata…

Critical 10-Year Vulnerability in Roundcube Webmail Allows Code Execution by Authenticated Users

On June 3, 2025, cybersecurity researchers revealed a significant security flaw in Roundcube webmail software, active for a decade, that could enable authenticated users to execute malicious code on vulnerable systems. Classified as CVE-2025-49113, the vulnerability has a CVSS score of 9.9 out of 10, highlighting its severity. It involves post-authentication remote code execution through PHP object deserialization. According to the National Vulnerability Database (NVD), “Roundcube Webmail versions before 1.5.10 and 1.6.x prior to 1.6.11 allow authenticated users to execute remote code due to the lack of validation for the _from parameter in the URL in program/actions/settings/upload.php.” This flaw affects all versions up to and including 1.6.10 but has been patched in versions 1.6.11 and 1.5.10 LTS. The vulnerability was discovered and reported by Kirill Firsov, founder and CEO of FearsOff.

Three distinct threat actors exploited countless elaborate fake profiles on Facebook and Instagram to conduct targeted attacks against individuals in South Asia. “These advanced persistent threats (APTs) relied heavily on social engineering tactics to deceive users into clicking malicious links, downloading malware, or sharing sensitive information online,” stated Guy Rosen, Meta’s chief information security officer. “This focus on social engineering reduced their need to invest heavily in malware development.” The counterfeit accounts utilized traditional tactics, pretending to be romantic interests, recruiters, journalists, or military personnel. Notably, two cyber espionage initiatives involved low-sophistication malware, likely attempting to evade app verification measures from Apple and Google. Meta’s findings revealed…
