Hackers Hide Malware in DNS Records to Evade Detection

An endpoint computer receiving a DNS response, which reassembles into a malicious script, shown as puzzle pieces forming a bug icon at the user’s terminal.A new cybersecurity threat is emerging as attackers use DNS records—the very system that directs internet traffic—to hide malware. Instead of relying on email attachments or suspicious downloads, bad actors are embedding malicious payloads into DNS TXT records. This method sneaks malicious code past traditional defenses because security tools often ignore DNS traffic.

DNS, or Domain Name System, acts like the internet’s phonebook, translating domain names into IP addresses. It is so fundamental and routine that most security systems allow it without scrutiny. That makes it a perfect hiding place. According to researchers at Infoblox, attackers are disguising shellcode—malicious binary instructions—inside base64-encoded TXT records. These look like harmless text but are reassembled and executed by compromised devices once fetched.  [Read more…]

The logo matches, the name checks out, and everything feels familiar. But something’s off. And before you realize what it is, you’ve handed over your login, your credit card, or worse, your network credentials. The trick wasn’t in the layout or the content. It was in the letters.

Cybercriminals are using homoglyphs—lookalike characters from other alphabets—to build fake domains that mimic real ones down to the pixel. A Cyrillic “а” is nearly identical to the Latin “a” your eyes expect to see. To a browser, they’re completely different. To a person, they’re the same. That’s the whole con. [Read more…]
