Threat actors have intensified their campaign using fake browser updates to spread malware, targeting over 6,000 WordPress sites via compromised plugins. GoDaddy reports that the ClickFix variant employs social engineering tactics to deceive users, leading to malware installation. Automated processes facilitate the creation of these malicious plugins, enhancing detection challenges.
**Meeting Takeaways: ClickFix Malware Campaign Overview**
1. **Threat Overview**:
– A new variant of malware, ClickFix, disguises itself as fake browser updates and has infected over 6,000 WordPress sites within a single day (Sept. 2-3).
2. **Attack Methodology**:
– Attackers use stolen WordPress admin credentials to log in and infect websites with malicious plug-ins.
– These plug-ins appear legitimate but contain scripts that prompt users to install harmful software disguised as browser updates.
3. **Campaign Characteristics**:
– ClickFix is linked to earlier campaigns like ClearFake, but significant differences suggest they are distinct operations.
– The campaign has been active since August 2023, affecting over 25,000 sites worldwide.
4. **Malicious Plug-ins**:
– The bogus plug-ins have generic names like “Advanced User Manager” and “Quick Cache Cleaner,” with fraudulent metadata that mimics authentic plug-ins.
– A systematic naming convention for JavaScript files indicates an automated process for creating these malicious plug-ins.
5. **Credential Theft**:
– Methods of acquiring credentials may include brute-force attacks and phishing.
– The malware can also steal credentials from infected systems, exacerbating the risk.
6. **Best Practices for Protection**:
– Website administrators are encouraged to follow password protection best practices and exercise caution with unknown websites and requests for credentials.
– GoDaddy has provided a list of indicators of compromise (IoCs) to help identify compromised sites.
7. **Response and Awareness**:
– The blog post by GoDaddy is aimed at raising awareness among website administrators regarding ongoing threats and providing actionable steps to enhance site security.
In summary, the ClickFix malware campaign represents a significant escalation in the use of fraudulent WordPress plug-ins to distribute malware, underscoring the need for heightened vigilance and proactive security measures in WordPress administration.
