North Korean Hackers Are Targeting Tech Job Seekers with Fake Interviews

 


Imagine landing a promising tech job interview, only to find out it’s a trap set by hackers. That’s the reality many software developers are facing, as North Korea-linked hackers use fake job interviews to spread malware. This malicious campaign, known as Contagious Interview, was uncovered by Palo Alto Networks' Unit 42 in late 2023.

How It Works

Hackers disguise themselves as employers on job platforms, offering interviews to unsuspecting developers. Victims are asked to download malware disguised as coding assignments. The attack begins with the installation of Beaver***, a downloader that works on both Windows and macOS systems. This then loads Invisible****, a Python-based backdoor designed to give attackers control over the infected system.

Their Sneaky Techniques

These hackers have refined their methods to stay effective:

  • They use fake video conferencing apps, built with the Qt framework, to spread malware seamlessly across platforms.
  • Once Beaver*** is installed, it steals browser passwords and data from cryptocurrency wallets, targeting up to 13 different wallets.

What’s Next?

The campaign appears financially motivated, likely funding the North Korean regime through cryptocurrency theft. Despite being exposed, the hackers haven’t changed their tactics much—because they work.

Stay Safe

If you’re a software developer or a tech job seeker, be cautious with unexpected interview requests or file downloads. Fake interviews could turn into more than just disappointment—they could be an open door to your sensitive data. Always verify the legitimacy of employers and avoid downloading files from untrusted sources.

Stay vigilant and protect your devices!

SPF 50 Won’t Even Protect You: Email Spoofing Surge Fuels Malspam Attacks!

Cybercriminals are ramping up email spoofing attacks , faking sender addresses to bypass security filters and trick victims into engaging with malicious content . While protocols like DKIM, DMARC, and SPF were designed to prevent spoofing, attackers are now exploiting neglected domains to slip past modern defenses. Old Tricks, New Domains   Hackers are leveraging abandoned or misconfigured domains to send fraudulent emails. These domains, unused for years, lack proper DNS records, allowing them to bypass email security systems undetected . Tactics in Play   Cybercriminals are using a mix of techniques to deceive users: Phishing with QR Codes : Fake tax-related emails (mainly in Mandarin) contain QR codes linking to phishing sites designed to steal IDs and card details . Brand Spoofs : Attackers impersonate trusted companies like Amazon, Mastercard, and SMBC , tricking users into entering credentials on fraudulent login pages. Extortion Scams : Fake emails claim hackers reco...
