Hackers Have Found an Entirely New Way To Backdoor Into Microsoft Windows

A university in Taiwan was breached with “a previously unseen backdoor (Backdoor.Msupedge) utilizing an infrequently seen technique,” Symantec reports.

The most notable feature of this backdoor is that it communicates with a command-and-control server via DNS traffic… The code for the DNS tunneling tool is based on the publicly available dnscat2 tool. It receives commands by performing name resolution… Msupedge not only receives commands via DNS traffic but also uses the resolved IP address of the C&C server (ctl.msedeapi[.]net) as a command. The third octet of the resolved IP address is a switch case. The behavior of the backdoor will change based on the value of the third octet of the resolved IP address minus seven…

The initial intrusion was likely through the exploit of a recently patched PHP vulnerability (CVE-2024-4577). The vulnerability is a CGI argument injection flaw affecting all versions of PHP installed on the Windows operating system. Successful exploitation of the vulnerability can lead to remote code execution.
Symantec has seen multiple threat actors scanning for vulnerable systems in recent weeks. To date, we have found no evidence allowing us to attribute this threat and the motive behind the attack remains unknown.

More from The Record:
Compared to more obvious methods like HTTP or HTTPS tunneling, this technique can be harder to detect because DNS traffic is generally considered benign and is often overlooked by security tools.
Earlier in June, researchers discovered a campaign by suspected Chinese state-sponsored hackers, known as RedJuliett, targeting dozens of organizations in Taiwan, including universities, state agencies, electronics manufacturers, and religious organizations. Like many other Chinese threat actors, the group likely targeted vulnerabilities in internet-facing devices such as firewalls and enterprise VPNs for initial access because these devices often have limited visibility and security solutions, researchers said.

Netflix Shares First Six Minutes of New Anime Series ‘Terminator Zero’

“It’s going to be violent,” warns the creator of Terminator Zero, an eight-episode anime series premiering Thursday August 29th on Netflix. “It’s going to be dark, it’s going to be horrific, and it’s going to be arresting.”

And the Netflix blog has now shared the first six minutes online:

In the world of Terminator, the future is never set, yet some things are guaranteed: The Terminator is still a cyborg that feels no remorse, pity, or fear. The anime series TERMINATOR ZERO, landing on Netflix on Aug. 29 — known to fans as Judgment Day — looks different from any incarnation of the Terminator franchise we’ve seen before, but you can tell from these opening six minutes that the brutal, sophisticated action will remain.
“I realized the first minutes of the show have to declare what it is,” creator and executive producer Mattson Tomlin tells Tudum. A joint production between Skydance and the Japanese animation studio Production I.G, TERMINATOR ZERO has the challenge of drawing in both anime fans and fans of the Terminator series. “The way to do that was to have a sequence that had no dialogue, that was really planting a flag in letting everybody know this is going to be violent, it’s going to be dark, it’s going to be action-driven, it’s going to be horrific, and it’s going to be arresting,” says Tomlin, who previously wrote Project Power for Netflix and is currently writing The Batman Part II. “That’s just what it has to be.”

The series follows “a new batch of characters who live in Japan in 1997,” writes CBR — and in an interview the show’s director said “There’s a balance” when representing Japan’s actual culture while keeping the show futuristic:
One of the things that I really took for granted was guns. [Points to self] Dumb American over here had to write a scene where Eiko gets into a parking lot and smashes the window of a car, goes to the glove box, takes out a revolver, and it instantly gets flagged. [Other people working on the series] were like, “No, we don’t have guns. What you are describing, that’s over there. We’re over here in civilization where that can’t happen.” That triggered a really fruitful and creatively challenging discussion about weapons. The military has guns and the police have guns. That’s kind of it. So these characters have to arm themselves. How are they going to do it? What could we do? And that’s why the Terminator has a crossbow. Eiko has all of these different weapons that she concocted from a hardware store. It was all born out of that.
