APT39: A Closer Look

Who’s Behind It?
APT39 is suspected to be linked to Iran, but what really matters is how this group is making its mark on industries across the globe. While they cast a wide net, their focus is sharp, with a significant presence in the Middle East. They’re not just dabbling—they’re zeroing in on sectors that you rely on daily: telecommunications, travel, and the IT firms that support them, as well as the high-tech industry.

What’s Their Game Plan?
APT39’s strategy is pretty clear-cut. They’re not just hacking for the thrill; they’ve got bigger fish to fry. By targeting the telecommunications and travel sectors, it’s obvious they’re into more than just data—they’re after the ability to monitor, track, and maybe even surveil specific individuals. They’re likely gathering proprietary or customer data for purposes that align with their national priorities. And let’s not overlook their interest in government entities, which suggests they’re also hunting for geopolitical intel to feed back into nation-state decision-making processes.

The Tools of the Trade
APT39 has its go-to tools, like the SEAWEED and CACHEMONEY backdoors, not to mention a specific variant of the POWBAT backdoor. These aren’t just off-the-shelf tools; they’re custom-crafted for precision operations.

How They Get In
The initial compromise methods used by APT39 are as crafty as they are effective. They often kick things off with a spearphishing attack, baiting their targets with malicious attachments or hyperlinks. If you’re not on your toes, you could end up with a POWBAT infection. They’ve also been known to hijack previously compromised email accounts, using the trust you place in familiar addresses to slip through the cracks. But that’s not all—they frequently set up domains that mimic legitimate services or organizations relevant to their targets. They’re adept at finding and exploiting vulnerable web servers, installing web shells like ANTAK and ASPXSPY to keep the backdoor open. And while they’ve mastered many tactics, they’ve yet to be seen exploiting software vulnerabilities—something to note, but no reason to let your guard down.
