The US Department of Justice has taken down a Twitter botnet operated by Russian news organization RT that was used to spread Kremlin propaganda on a large scale across Europe and the US.
According to court documents, the botnet consisted of at least 968 accounts and was operated by an editor-in-chief from RT's Moscow headquarters.
The botnet was established in early 2022, shortly after Russia's invasion of Ukraine, and its main role was to spread disinformation and favorable Russian narratives about the war.
According to a technical report [PDF] published by the FBI, RT used an AI tool named Meliorator to build and control the botnet's behavior.
This tool consists of two main components—Brigadir (frontend) and Taras (backend). From the FBI report:
"Brigadir serves as the primary end user interface of Meliorator and functions as the administrator panel. Brigadir serves as the graphical user interface for the Taras application and includes tabs for “souls,” false identities that would create the basis for the bots, and “thoughts,” which are the automated scenarios or actions that could be implemented on behalf of the bots, such as sharing content to social media in the future."

The botnet allowed operators to create fake online persons, register a Twitter account on their behalf, bypass Twitter verifications using an on-board email server, and configure campaigns on certain topics and with automated replies.
The bots were configured to take the identities of local citizens but would often post Russian propaganda and disinformation.
RT and its ilk used Meliorator to spread propaganda targeting audiences in the US, Poland, Germany, the Netherlands, Spain, Ukraine, and Israel.
The FBI says the tool was designed for use on Twitter, but it could have been easily adapted to other social networks as well.
The DOJ says it discovered the botnet after identifying Meliorator control panels operating on two domains, on mlrtr[.]com and otanmailp[.]com, both of which were registered with identities linked to the (yet unnamed) RT Moscow editor-in-chief.
The Justice Department says the narratives would often come from a private intelligence organization (PIO) controlled by a Russian FSB officer that was established with the approval and financial support of the Presidential Administration of Russia.
Both the RT editor-in-chief and the FSB officer had direct access to the Meliorator control panels, per the DOJ.
The DOJ praised Twitter (now X, but we're not calling it that since nobody calls it that) for its voluntary takedown of all bot accounts.

[This item has been edited post-publication due to an erroneous description.]
AU assessment: The Australian government will run a stocktake of all its internet-facing systems and services by June next year. Government agencies will have to scan and determine what equipment and software they have exposed on the internet and from what software vendor or contractor. The end goal is to create a security risk management plan for all internet-facing systems or services. [Additional coverage in itNews]
Russian oppression database: The Russian government has built a database of all citizens who have fled the country after its invasion of Ukraine. The database is very likely being used for oppression purposes. The Kremlin previously used a leaked database of Navalny donors to fire government employees and detain individuals on charges of supporting terrorism. [Additional coverage in The Agency]
Russian censorship: Apple has removed 25 VPN apps from the Russian version of its App Store following a request from the country's telecommunications watchdog. The move comes after the Roskomnadzor has tried and failed to block VPN protocols at the network level for almost two years.

Cybercrime and threat intel
VasyGrek: Russian security firm FACCT has linked a malware developer known as Mr.Burns to a 38-year-old Ukrainian national. FACCT claims Andrey R. from the city of Ternopil has been involved in cybercrime since 2010 and is the author and seller of the Burns remote access trojan. The company says the BurnsRAT is a tool commonly used by VasyGrek, a cybercrime group that has been attacking Russian companies since at least 2020.

Malware technical reports
DoNeX ransomware: Security firm Avast has been secretly working with law enforcement authorities to provide free decrypters for victims of the DoNeX ransomware gang. Avast says it built the decrypter in March after its researchers found a flaw in the ransomware's cryptographic scheme. The company revealed its decrypter after details of the same flaw were disclosed at a recent security conference. The decrypter works on users infected by the DoNeX ransomware, as well as previous versions known as DarkRace and Muse.
Coyote: BlackBerry has published a report on Coyote, a new banking trojan spotted earlier this year that primarily targets Brazilian financial institutions.

APTs, cyber-espionage, and info-ops
APT40: Australia's cybersecurity agency has published a report and IOCs from two recent APT40 intrusions. The report marks the first time Australia has led the publishing and exposing of a Chinese APT's ops as part of a joint effort with other agencies abroad.
"The activity and techniques overlaps with the groups tracked as Advanced Persistent Threat (APT) 40, Kryptonite Panda, GINGHAM TYPHOON, Leviathan and Bronze Mohawk in industry reporting. This group has previously been reported as being based in Haikou, Hainan Province, PRC and receiving tasking from the PRC MSS, Hainan State Security Department."
CloudSorcerer: Kaspersky has discovered a new APT group targeting Russian government entities. The new CloudSorcerer group has been active since May this year. Its main tool is a sophisticated toolkit designed to control malware implants and exfil data via Microsoft Graph, Yandex Cloud, and Dropbox cloud infrastructure. Kaspersky did not link the group to any state. Proofpoint says it spotted the same group also targeting US think tanks.
Lifting Zmiy: Rostelecom's security team has discovered a new APT group that is breaching companies via industrial PLCs. Named Lifting Zmiy, the group's first attacks were traced back to October of last year. The group targeted PLCs from Russian company Tech-Automatics usually used with elevators and which were still using their default passwords. Rostelecom has linked the group to intrusions at a Russian government contractor, two telecom operators, and an IT company. The company says the group collected and exfiltrated data and then destroyed the victim's infrastructure. Rostelecom says Lifting Zmiy uses Starlink infrastructure for attacks and appears to operate out of Ukraine.
Kimsuky: Japan's CERT team has published a report looking at Kimsuky operations targeting Japanese organizations.
DPRK npm malware: DevSecOps company Phylum has found another malicious JS library published on the npm portal by North Korean hackers. This one tried to pass as call-bind is a legitimate npm package with over 2,000 downstream dependents and over 45 million weekly downloads.
Houthi cyber ops, part I: Hackers linked with Houthi rebels have used spyware to target militaries across the Middle East since 2019. The attacks used a novel spyware strain named GuardZoo to collect photos and documents from infected devices. Targets included militaries in seven Middle East countries, such as Saudi Arabia, Oman, and Egypt. Security firm Lookout spotted the infections after it discovered a GuardZoo command and control server exposed online.
Houthi cyber ops, part II: On the same note, another Houthi-linked cyber group named OilAlpha has continued to use malicious mobile apps to target humanitarian and human rights organizations operating in Yemen. This is a continuation of a campaign that was first spotted last year.
