Russian FSB Cyber Actor Star Blizzard Continues Worldwide Spear-phishing Campaigns | CISA
Russian FSB Cyber Actor Star Blizzard Continues Worldwide Spear-phishing Campaigns | CISA
The Russia-based actor Star Blizzard (formerly known as SEABORGIUM, also known as Callisto Group/TA446/COLDRIVER/TAG-53/BlueCharlie) continues to successfully use spear-phishing attacks against targeted organizations and individuals in the UK, and other geographical areas of interest, for information-gathering activity. The UK National Cyber Security Centre (NCSC), the US Cybersecurity and Infrastructure Security Agency (CISA), the US Federal Bureau of Investigation (FBI), the US National Security Agency (NSA), the US Cyber National Mission Force (CNMF), the Australian Signals Directorate’s Australian Cyber Security Centre (ASD’s ACSC), the Canadian Centre for Cyber Security (CCCS), and the New Zealand National Cyber Security Centre (NCSC-NZ) assess that Star Blizzard is almost certainly subordinate to the Russian Federal Security Service (FSB) Centre 18.

Meet the Unique New "Hacking" Group: AlphaLock
Meet the Unique New "Hacking" Group: AlphaLock
It’s not every day that you discover a new Russian hacking group complete with a song and dance routine (performed live), a sleek user interface (with dark mode!) and a clearly thought-out business model. But that is exactly what our security research team discovered with “AlphaLock,” a “pentesting training organization” that trains hackers and then monetizes their services through a dedicated affiliate program. ... We originally discovered their group through a public Telegram channel that has since become private. This post will serve as a detailed investigation and description of one of the most brazen, strange, and best marketed cybercrime groups to appear in 2023. Cybercrime sophistication and commoditization continues to grow: We now have a real life example of a threat group that seeks to create its own talent pool through a training program, goes to extensive lengths to market itself, and plans to monetize this through a hacker-for-hire scheme. The level of technical sophistication required to do this isn’t very high, but the level of organizational sophistication and business acumen is quite interesting. Ransomware isn’t the only game in town: Cybercriminals typically choose the path of least resistance that is most likely to prove profitable, this has been increasingly the case as the cybercrime ecosystem has evolved into a functional market economy. However AlphaLock represents another potential method to both monetize and democratize cybercrime. This could be a particularly interesting model alternative for ransomware groups if the U.S. follows through with the proposal of banning ransomware payments. A Technical Threat Actor Supply Shortage? One of the most fascinating things about AlphaLock is they want to create a pipeline of talent to populate their hacker marketplace. This suggests that there may be limitations on the supply of talented threat actors that have the required degree of sophistication to the point where they have tried to build their own pipeline of actors. The Brand: Our researchers have noted an increasing focus on group “brand” and identity among financially motivated threat groups. AlphaLock has clearly made significant investments in time to create a brand and reputation for itself. Notice in the final post they even advertise that they are looking to hire someone to market themselves on Telegram and social media. * Blurred Lines: Many security practitioners have often assumed that threat actors primarily operate on the dark web. In most cases today this isn’t the case. There are increasingly blurred lines between clear web sites, Tor, and social media applications such as Telegram that create easy avenues for threat actors to congregate and communicate.

Justice Department Announces Court-Authorized Disruption of the Snake Malware Network Controlled by Russia's Federal Security Service
“Russia used sophisticated malware to steal sensitive information from our allies, laundering it through a network of infected computers in the United States in a cynical attempt to conceal their crimes.  Meeting the challenge of cyberespionage requires creativity and a willingness to use all lawful means to protect our nation and our allies,” stated United States Attorney Peace.  “The court-authorized remote search and remediation announced today demonstrates my Office and our partners’ commitment to using all of the tools at our disposal to protect the American people.”

Hunting Russian Intelligence “Snake” Malware
Hunting Russian Intelligence “Snake” Malware
The Snake implant is considered the most sophisticated cyber espionage tool designed and used by Center 16 of Russia’s Federal Security Service (FSB) for long-term intelligence collection on sensitive targets. To conduct operations using this tool, the FSB created a covert peer-to-peer (P2P) network of numerous Snake-infected computers worldwide. Many systems in this P2P network serve as relay nodes which route disguised operational traffic to and from Snake implants on the FSB’s ultimate targets. Snake’s custom communications protocols employ encryption and fragmentation for confidentiality and are designed to hamper detection and collection efforts.

From Discord to 4chan: The Improbable Journey of a US Intelligence Leak - bellingcat
In recent days, the US Justice Department and Pentagon have begun investigating an apparent online leak of sensitive documents, including some that were marked “Top Secret”. A portion of the documents, which have since been widely covered by the news media, focused on Russia’s invasion of Ukraine, while others detailed analysis of potential UK policies on the South China Sea and the activities of a Houthi figure in Yemen. The existence of the documents was first reported by the New York Times after a number of Russian Telegram channels shared five photographed files relating to the invasion of Ukraine on April 5 – at least one of which has since been found by Bellingcat to be crudely edited.

Exploitation is a Dish Best Served Cold: Winter Vivern Uses Known Zimbra Vulnerability to Target Webmail Portals of NATO-Aligned Governments in Europe
Exploitation is a Dish Best Served Cold: Winter Vivern Uses Known Zimbra Vulnerability to Target Webmail Portals of NATO-Aligned Governments in Europe
  • Proofpoint has observed recent espionage-related activity by TA473, including yet to be reported instances of TA473 targeting US elected officials and staffers. TA473 is a newly minted Proofpoint threat actor that aligns with public reporting on Winter Vivern. * TA473 since at least February 2023 has continuously leveraged an unpatched Zimbra vulnerability in publicly facing webmail portals that allows them to gain access to the email mailboxes of government entities in Europe. * TA473 recons and reverse engineers bespoke JavaScript payloads designed for each government targets’ webmail portal. * Proofpoint concurs with Sentinel One analysis that TA473 targeting superficially aligns with the support of Russian and/or Belarussian geopolitical goals as they pertain to the Russia-Ukraine War.
