Advanced persistent threat group Fancy Bear is behind a phishing campaign that uses the specter of nuclear war to exploit a known one-click Microsoft flaw.
The goal is to deliver malware that can steal credentials from the Chrome, Firefox and Edge browsers.

The attacks by the Russia-linked APT are tied the Russian and Ukraine war, according to researchers at Malwarebytes Threat Intelligence. They report that Fancy Bear is pushing malicious documents weaponized with the exploit for Follina (CVE-2022-30190), a known Microsoft one-click flaw, according to a blog post published this week.

“This is the first time we’ve observed APT28 using Follina in its operations,” researchers wrote in the post. Fancy Bear is also known as APT28, Strontium and Sofacy.

On June 20, Malwarebytes researchers first observed the weaponized document, which downloads and executes a .Net stealer first reported by Google. Google’s Threat Analysis Group (TAG) said Fancy Bear already has used this stealer to target users in the Ukraine.

The Computer Emergency Response Team of Ukraine (CERT-UA) also independently discovered the malicious document used by Fancy Bear in the recent phishing campaign, according to Malwarebytes. Bear on the LooseCERT-UA previously identified Fancy Bear as one of the numerous APTs pummeling Ukraine with cyber-attacks in parallel with the invasion by Russian troops that began in late February. The group is believed to be operating on the behest of Russian intelligence to gather info that would be useful to the agency.

Researchers first flagged Follina in April, but only in May was it officially identified as a zero-day, one-click exploit. Follina is associated with the Microsoft Support Diagnostic Tool (MSDT) and uses the ms-msdt protocol to load malicious code from Word or other Office documents when they’re opened.

The bug is dangerous for a number of reasons–not the least of which is its wide attack surface, as it basically affects anyone using Microsoft Office on all currently supported versions of Windows. If successfully exploited, attackers can gain user rights to effectively take over a system and install programs, view, change or delete data, or create new accounts.

Microsoft recently patched Follina in its June Patch Tuesday release but it remains under active exploit by threat actors, including known APTs.
Threat of Nuclear Attack
Fancy Bear’s Follina campaign targets users with emails carrying a malicious RTF file called “Nuclear Terrorism A Very Real Threat” in an attempt to prey on victims’ fears that the invasion of Ukraine will escalate into a nuclear conflict, researchers said in the post. The content of the document is an article from the international affairs group Atlantic Council that explores the possibility that Putin will use nuclear weapons in the war in Ukraine.

The malicious file uses a remote template embedded in the Document.xml.rels file to retrieve a remote HTML file from the URL http://kitten-268[.]frge[.]io/article[.]html. The HTML file then uses a JavaScript call to window.location.href to load and execute an e[...]

ncoded PowerShell script using the ms-msdt MSProtocol URI scheme, researchers said.

While the oldest variant of the stealer used a fake error message pop-up to distract users from what it was doing, the variant used in the nuclear-themed campaign does not, researchers said.

In other functionality, the recently seen variant is “almost identical” to the earlier one, “with just a few minor refactors and some additional sleep commands,” they added.

As with the previous variant, the stealer’s main pupose is to steal data—including website credentials such as username, password and URL–from several popular browsers, including Google Chrome, Microsoft Edge and Firefox. The malware then uses the IMAP email protocol to exfiltrate data to its command-and-control server in the same way the earlier variant did but this time to a different domain, researchers said.

“The old variant of this stealer connected to mail[.]sartoc.com (144.208.77.68) to exfiltrate data,” they wrote. “The new variant uses the same method but a different domain, www.specialityllc[.]com. Interestingly both are located in Dubai.”

The owners of the websites most likely have nothing to do with APT28, with the group simply taking advantage of abandoned or vulnerable sites, researchers added.

hacking: security in practice
Is IT blocking hotspot and router access through ethernet?

So the IT team at my university has started cracking down on students for using too much internet (even though it is unlimited) during class hours (streaming Netflix, torrenting MASSIVE files, etc).

They use MAC filtering for each student to limit how many devices can connect to the network. Luckily I have some Linux/basic hacking knowledge and used macchanger to change my MAC in order to bypass this.

Then they started manually blocking devices based on their usage. Eg if someone was using Netflix, connected to a VPN or proxy to bypass firewall restrictions, or had P2P (torrent) traffic on the network, they would block that device from connecting for 24 hours. Also, they started slowing the speed from gigabit to less than 10 Mbps, so now barely anything works.

We also have ethernet ports throughout the campus and in classes, which don't have any of these restrictions (other than MAC filtering), but the problem is they have somehow blocked the use of ethernet hotspot creation. I have a travel router and whenever I try to connect it with the ethernet, the router cannot give out internet access as an access point. My router has a setting to clone MAC addresses, so I have changed the MAC, but whenever I connect the port it shows up as having no internet through a connected laptop or phone.

I tried connecting my laptop directly to the ethernet port and see what happens, and somehow when I connect everything works just fine, but as soon as I open my mobile hotspot from the settings my internet gets disconnected and I have to reconnect.

First, I want to understand how they are even doing this. Also, I want to learn if there would be a way to bypass this so i can connect my router and create a hotspot.
