Who is doing what to whom and how allegedly.
Reporting on Russia
Hybrid Russian Espionage and Influence Campaign Aims to Compromise Ukrainian Military Recruits and Deliver Anti-Mobilization Narratives
Google Threat Intelligence Group detail a campaign which they allege is Russia. Notable for using paid promoted posts on Telegram.
UNC5812’s malware delivery operations are conducted both via an actor-controlled Telegram channel
@civildefense_com_uaand website hosted atcivildefense[.]com.ua. The associated website was registered in April 2024, but the Telegram channel was not created until early September 2024, which we judge to be when UNC5812’s campaign became fully operational. To drive potential victims towards these actor-controlled resources, we assess that UNC5812 is likely purchasing promoted posts in legitimate, established Ukrainian-language Telegram channels.
On September 18th 2024, a legitimate channel with over 80,000 subscribers dedicated to missile alerts was observed promoting the "Civil Defense" Telegram channel and website to its subscribers.
An additional Ukrainian-language news channel promoting Civil Defense’s posts as recently as October 8th, indicating the campaign is probably still actively seeking new Ukrainian-language communities for targeted engagement.
Channels where "Civil Defense" posts have been promoted advertise the ability to reach out to their administrations for sponsorship opportunities. We suspect this is the likely vector that UNC5812 is using to approach the respective legitimate channels to increase the operation’s reach.
Beyond Their Intended Scope: Uzing into Russia
Doug Madory details what might be a faux par or might of been something more malicious leading to BGP leaks re-routing traffic to places it should have not gone..
Beginning at 06:25 UTC on September 26, 2024, Uztelecom (AS28910), incumbent of the former Soviet republic of Uzbekistan, began leaking routes from its peers through one of its transit providers, Rostelecom (AS12389), Russia’s state telecom. First reported by our friends over at Qrator, the incident involved the leak of over 3,000 routes lasting about 40 minutes misdirecting traffic from a dozen countries.
Another prefix sucked into the leak (162.158.84.0/24) belonged to Cloudflare.

Midnight Blizzard conducts large-scale spear-phishing campaign using RDP files
Microsoft Threat Intelligence further details a campaign which was covered here last week which they allege is Russia. Their reporting gives a sense of the scale of the campaign.
The spear-phishing emails in this campaign were sent to thousands of targets in over 100 organizations and contained a signed Remote Desktop Protocol (RDP) configuration file that connected to an actor-controlled server. In some of the lures, the actor attempted to add credibility to their malicious messages by impersonating Microsoft employees. The threat actor also referenced other cloud providers in the phishing lures.
Reporting on China
Chinese threat actor Storm-0940 uses credentials from password spray attacks from a covert network
Microsoft Threat Intelligence details a covert network which appears to be retooling to avoid detection in support of a threat actor they allege is the Chinese state.
Since August 2023, Microsoft has observed intrusion activity targeting and successfully stealing credentials from multiple Microsoft customers that is enabled by highly evasive password spray attacks. Microsoft has linked the source of these password spray attacks to a network of compromised devices we track as CovertNetwork-1658, also known as xlogin and Quad7 (7777).
After successfully gaining access to a vulnerable router, in some instances, the following steps are taken by the threat actor to prepare the router for password spray operations:
Download Telnet binary from a remote File Transfer Protocol (FTP) server
Download xlogin backdoor binary from a remote FTP server
Utilize the downloaded Telnet and xlogin binaries to start an access-controlled command shell on TCP port 7777
Connect and authenticate to the xlogin backdoor listening on TCP port 7777
Download a SOCKS5 server binary to router
Start SOCKS5 server on TCP port 11288
..
Microsoft assesses that CovertNetwork-1658 has not stopped operations as indicated in recent activity but is likely acquiring new infrastructure with modified fingerprints from what has been publicly disclosed.
Pacific Rim: Inside the Counter-Offensive—The TTPs Used to Neutralize China-Based Threats
Sophos detail the timeline in this campaign they attribute to China which I count involved at least five zero-days over five years. Sophos should be applauded for the transparency here.
Throughout the campaigns, the actors became increasingly adept at hiding their activities from immediate discovery by blocking telemetry from being sent from the device to Sophos.
As early as April 2020, the attackers made efforts to sabotage the hotfix mechanism of devices they compromised. Later, they added targeting of the telemetry system of devices to prevent Sophos from getting early warning of their activity.
The actors also discovered and blocked telemetry-gathering on their own test devices after Sophos X-Ops utilized that capability to collect data on exploits while they were being developed.
Additionally, the operational security practices of the exploit developers improved over time. X-Ops saw the trail of data we could follow with open-source intelligence practices shrink considerably from earlier attacks.

CloudScout: Evasive Panda scouting cloud services
Anh Ho details a cloud campaign which they allege is Chinese in origination. This is what contemporary threat actor tradecraft looks like in 2024.. Note the regional targeting.
The CloudScout toolset was detected in Taiwan, between 2022 and 2023, in the network of a religious institution and at a government entity.
CloudScout utilizes stolen cookies, provided by MgBot plugins, to access and exfiltrate data stored at various cloud services.
We analyzed three CloudScout modules, which aim to steal data from Google Drive, Gmail, and Outlook. We believe that at least seven additional modules exist.
Hardcoded fields in CloudScout’s web requests for stealing Outlook email messages suggest that the samples involved were crafted to target Taiwanese users.
Each CloudScout module, programmed in C#, is deployed by an MgBot plugin, programmed in C++.

LightSpy: Implant for iOS
Threat Fabric show that a threat actor they allege is in China was able to leverage various old-days in their Apple iOS capability. Of note is the sophistication and investment made here.
The threat actor expanded support for the iOS platform, targeting up to version 13.3. They utilized the publicly available Safari exploit CVE-2020-9802 for initial access and CVE-2020-3837 for privilege escalation.
The actor ran multiple campaigns with varying sets of plugins. One particular campaign included plugins that could disrupt the operating system’s stability, with capabilities to freeze the device or even prevent it from booting up.
Finally, an interesting observation was found in the location plugin. The plugin contains a function that recalculates location coordinates according to a system used exclusively in China, strongly indicating that LightSpy operators are likely based in China.

Reporting on North Korea
Jumpy Pisces Engages in Play Ransomware
Unit 42 highlights a trend which if their allegation is true that this is the North Korean state should be a warning to all organisations. That is further alleged state involvement in ransomware..
Unit 42 has identified Jumpy Pisces, a North Korean state-sponsored threat group associated with the Reconnaissance General Bureau of the Korean People's Army, as a key player in a recent ransomware incident. Our investigation indicates a likely shift in the group’s tactics. We believe with moderate confidence that Jumpy Pisces, or a faction of the group, is now collaborating with the Play ransomware group (Fiddling Scorpius).
This change marks the first observed instance of the group using existing ransomware infrastructure, potentially acting as an initial access broker (IAB) or an affiliate of the Play ransomware group. This shift in their tactics, techniques and procedures (TTPs) signals deeper involvement in the broader ransomware threat landscape.

APT Group - Konni Launches New Attacks on South Korea
Threat Book detail what they alleged is a North Korean campaign. The thing of note in this reporting is the use of automation to mass-produce the implant samples.
lFrom mid-April to early July 2024, the Konni group launched attacks on South Korea’s RTP engineering department and personnel involved in tax and North Korea market analysis. The group used malicious samples with Korean themes such as “meeting materials,” “tax evasion,” and “market prices” for the attack;
lThe Konni group used automated tools to mass-produce malicious samples, all of which were generated at the same moment on December 25, 2023, at 11:39:35, but were delivered at different times in 2024. It is speculated that a script tool was used to generate malicious samples based on templates, and the actual number of delivered samples may be large, but only six in-the-wild samples have been discovered so far. This type of sample delivery is still very active, with the latest in-the-wild sample discovered on July 6th;
lThe malicious samples used by the Konni group host the core payload on a compromised website in the execution chain. Although the core payload’s lifespan is extremely short, the malicious samples have been persistent on the infected host, so it cannot be ruled out that the group will reuse the core payload in the future. In addition, the core payload uses AutoIt3 scripts for evasion, which is very effective. Since the core payload was submitted in April 2024, it has not been detected by multiple engines.

Reporting on Iran
New Tradecraft of Iranian Cyber Group Aria Sepehr Ayandehsazan aka Emennet Pasargad
The Federal Bureau of Investigation (FBI), U.S. Department of Treasury, and Israel National Cyber Directorate warn of new cyber tradecraft of the Iranian cyber group Emennet Pasargad, which has been operating under the company name Aria Sepehr Ayandehsazan (ASA) and is known by the private sector terms Cotton Sandstorm, Marnanbridge, and Haywire Kitten.
FBI also acquired information indicating that since approximately mid-2023, ASA has used several cover hosting providers for infrastructure management and obfuscation. These two providers are ”Server-Speed” (server-speed[.]com) and ”VPS-Agent” (vps-agent[.]net8). Whereas actors typically procure virtual infrastructure from hosting resellers, ASA set up its own resellers and procured server space from Europebased providers, including the Lithuania-based company BAcloud and Stark Industries Solutions/PQ Hosting (located in the United Kingdom and Moldova, respectively). ASA then leverages these cover resellers to provision operational servers to its own cyber actors for malicious cyber activities. FBI has also observed ASA using these cover re-sellers to provide technical support to identified Lebanon-based individuals, including with hosting for HAMAS-affiliated or themed websites.

Reporting on Other Actors
Inside Intelligence Center: LUNAR SPIDER Enabling Ransomware Attacks on Financial Sector with Brute Ratel C4 and Latrodectus
EclecticIQ Threat Research Team detail a criminal campaign which has it all. Malvertising, use of a commercial implant framework and then the group continuing despite their leader being extradited.
In October 2024, EclecticIQ analysts observed a malvertising campaign employing an obfuscated JavaScript downloader known as Latrodectus to deliver a malicious payload associated with Brute Ratel C4 (BRc4) Analysts assess with high confidence that this campaign is very likely linked to LUNAR SPIDER, a Russian-speaking, financially motivated threat actor group active since at least 2009. LUNAR SPIDER is responsible for developing several high-profile malware families, including IcedID and Latrodectus. IcedID malware is often distributed via malware-as-a-service (MaaS) offerings, enabling affiliates, such as the ALPHA SPIDER/BlackCat ransomware group, to leverage these services for initial compromise.
Despite his extradition to the United States and sentencing to 18 years in prison in 2024, LUNAR SPIDER continues to operate, adapting to leadership changes and law enforcement actions with resilience.
Katz and Mouse Game: MaaS Infostealers Adapt to Patched Chrome Defenses
Jia Yu Chan, Salim Bitam, Daniel Stepanic, Samir Bousseaden, Cyril François and Seth Goodwin detail a campaign which integrated an open source capability which predicted would likely be used to continue their capability.

Silencing the EDR Silencers
Jonathan Johnson provides a potential detection technique for those who are trying to silence EDR telemetry.
Now, it’s good to note that with Windows AV turned on, Defender does block firewall rules being made against MsMpEng.exe. However, the key point is that this can be done against any EDR, and if they’re not monitoring, the network communications will be cut off. When these firewall rules are created, they’re actually stored in the registry

Then you can use Conditional Access authentication strengths policies to enforce passkey sign-in when users access a sensitive resource.
Reference Architecture for Confidential Data Processing in a Trusted Execution Environment
Google details their reference architecture..
TEE (Trusted Execution Environment) based solutions offer robust security, privacy and transparency for personal data and computations.
They achieve this through a layered architecture:
Hardware Foundation
Hardware Isolation: The TEE operates within a physically and logically isolated section of the main processor. This creates a cryptographic barrier between the operations within the TEE and potential threats in the broader system.
Operator and Insider Protection: TEE’s isolate processing such that even those with administrative privileges to the main system cannot directly access or manipulate the TEE's contents. This safeguards against both external attacks and misuse by privileged users.
Attestation: The TEE can generate cryptographic proof of its identity and the code it's running. This allows external systems to verify the TEE's identity at runtime. It should be noted that this identity is immutable and tamper proof.
Data Protection
Encryption/Decryption: Data entering or leaving the TEE is encrypted, ensuring its confidentiality outside the protected environment. Within the TEE, the data can be decrypted but is isolated and protected from anyone per the protections outlined above.
Attestation-Based Key Management: Decrypting data relies on attestation and policy evaluation. If the TEE's code or configuration isn't as expected per participant controlled policy, decryption keys are withheld which prevents unauthorized access.
Online Attestation: Attestation offers a critical security layer for clients who need to communicate confidentially with a TEE. By establishing the TEE’s identity via cryptographic attestation, clients can independently validate the code and configuration the TEE runs on. This validation process ensures the TEE is genuine and secure, allowing for trustworthy data exchange.
A deep dive into Linux’s new mseal syscall
Alan Cao details a new Linux mitigation which landed in 6.10 which will have a range of applications..
Memory sealing allows developers to make memory regions immutable from illicit modifications during program runtime. When a virtual memory address (VMA) range is sealed, an attacker with a code execution primitive cannot perform subsequent virtual memory operations to change the VMA’s permissions or modify how it is laid out for their benefit.

Chrome App Bound Encryption Decryption
Alex releases a tool which we can expect to be used maliciously is 3..2..
This tool decrypts App-Bound Encrypted (ABE) keys stored in the Local State file of supported Chromium-based browsers, including Google Chrome, Brave, and Microsoft Edge. ABE, introduced in Chrome version 127, binds decryption capabilities to specific applications to prevent unauthorized access to sensitive data such as cookies (and potentially passwords and payment information in the future). This tool leverages the internal COM-based IElevator service, unique to each browser, to retrieve and decrypt these keys.

Exploitation
What is being exploited..
Increased Fog and Akira Ransomware Activity Linked to SonicWall SSL VPN
Steven Campbell, Akshay Suthar, and Stefan Hostetler show that old-days are being exploited by criminals..
Arctic Wolf has observed an influx of at least 30 Akira and Fog intrusions across a variety of industries since early August, each involving SonicWall SSL VPN early in the cyber kill chain.
Malicious VPN logins originated from IP addresses associated with VPS hosting, providing defenders with a viable mechanism for early detection and prevention.
None of the affected SonicWall devices were patched against CVE-2024-40766, which SonicWall indicates is potentially under active exploitation.
Shared IP infrastructure was seen across several Akira and Fog intrusions.
A short interval between initial SSL VPN account access and ransomware encryption was observed, often within the same day.
