Hackers send resumes with more_eggs malware to recruiters
Researchers from the Canadian company eSentire have reported a new wave of phishing attacks using resumes embedded with the more_eggs malware. Cybercriminals have attacked corporate recruiters with fake resumes.
Cybersecurity researchers have identified and prevented four separate cyber incidents, three of which occurred at the end of March this year. Affected entities include a US-based aerospace company, an accounting firm based in the UK, and a law firm and recruitment agency based outside of Canada.
Let me remind you that we, for example, talked about Hancitor malware, which uses phishing emails, compromised credentials, or brute-forcing RDP to access vulnerable Windows machines. А также, что Mars’ new infostealer is being distributed via OpenOffice ads on Google.
A year ago, in the pre-Easter period, experts also discovered a targeted phishing campaign infecting victims with more_eggs. However, during this operation, the attackers were targeting LinkedIn professionals who were looking for jobs, not hiring managers looking for job candidates. The hackers sent ZIP files to job seekers disguised as job offers. When criminal targets an opened the zip file, it causes installation of the more_eggs.
The malware, allegedly developed by the Golden Chickens (also known as the Venom Spider), is a stealthy, modular set of backdoors capable of stealing valuable information and traversing a compromised network.
Experts believe that anti-virus software may not be enough to protect against such a complex attack system as more_eggs.
Recommendations on how to avoid becoming a victim of More_Eggs:
- Safety training for all employees. Safety training should be mandatory for all company employees.
- Users should avoid downloading and running files from unverified sources. For example, be wary of Word and Excel documents sent from an unknown source or obtained from the Internet that prompt users to “Enable Macros”.
- Avoid free versions of paid software. Always check the full URL before downloading files to make sure it matches the origin (for example, Microsoft Team must come from a Microsoft domain).
- Check file extensions, don’t just trust the file type logo. The executable file can be disguised as a PDF.
- Ensure that there are standard procedures in place for employees to submit potentially harmful content for review.
