The Darkside of TheMoon
Executive Summary The Black Lotus Labs team at Lumen Technologies has identified a multi-year campaign targeting end-of-life (EoL) small home/small office (SOHO) routers and IoT devices, associated with an updated version of “TheMoon” malware. TheMoon, which emerged in 2014, has been operating quietly while growing to over 40,000 bots from 88 countries in January and

Key Lesson from Microsoft's Password Spray Hack: Secure Every Account
Key Lesson from Microsoft's Password Spray Hack: Secure Every Account
In January 2024, Microsoft discovered they'd been the victim of a hack orchestrated by Russian-state hackers Midnight Blizzard (sometimes known as Nobelium). The concerning detail about this case is how easy it was to breach the software giant. It wasn't a highly technical hack that exploited a zero-day vulnerability – the hackers used a simple password spray attack to take control of an old, inactive account. This serves as a stark reminder of the importance of password security and why organizations need to protect every user account.

Details and Lessons Learned From the Ransomware Attack on the British Library
The British Library has shared details on the destructive ransomware attack it experienced in October 2023. Although the attack on the national library of the UK occurred five months ago, the Library’s infrastructure won’t be rebuilt until mid-April 2024, and then the full restoration of systems and data can begin.

Ransomware Diaries: Volume 1
Ransomware Diaries: Volume 1
The LockBit ransomware gang is one of the most notorious organized cybercrime syndicates that exists today. The gang is behind attacks targeting private-sector corporations and other high-profile industries worldwide. News and media outlets have documented many LockBit attacks, while security vendors offer technical assessments explaining how each occurred. Although these provide insight into the attacks, I wanted to know more about the human side of the operation to learn about the insights, motivations, and behaviors of the individuals on the other side of the keyboard. To prepare for this project, I spent months developing several online personas and established their credibility over time to gain access to the gang’s operation.

Shc Linux Malware Installing CoinMiner
Shc Linux Malware Installing CoinMiner
The ASEC analysis team recently discovered that a Linux malware developed with Shc has been installing a CoinMiner. It is presumed that after successful authentication through a dictionary attack on inadequately managed Linux SSH servers, various malware were installed on the target system. Among those installed were the Shc downloader, XMRig CoinMiner installed through the former, and DDoS IRC Bot, developed with Perl.

LockBit ransomware suspect nabbed in Canada, faces charges in the US
Automation features make LockBit one of the more destructive pieces of ransomware. Federal prosecutors on Thursday charged a dual Russian and Canadian national for his alleged participation in a global campaign to spread ransomware known as LockBit. Mikhail Vasiliev, 33, of Bradford, Ontario, Canada, was taken into custody in late October by authorities in Ontario, officials at Interpol said. He is now in custody in Canada awaiting extradition to the US.

Tech tool offers police ‘mass surveillance on a budget’
Local law enforcement agencies from suburban Southern California to rural North Carolina have been using an obscure cellphone tracking tool, at times without search warrants, that gives them the power to follow people’s movements months back in time, according to public records and internal emails obtained by The Associated Press.

Comprehensive Threat Intelligence: Cisco Talos shares insights related to recent cyber attack on Cisco
  • On May 24, 2022, Cisco became aware of a potential compromise. Since that point, Cisco Security Incident Response (CSIRT) and Cisco Talos have been working to remediate. * During the investigation, it was determined that a Cisco employee’s credentials were compromised after an attacker gained control of a personal Google account where credentials saved in the victim’s browser were being synchronized.

A new botnet Orchard Generates DGA Domains with Bitcoin Transaction Information
DGA is one of the classic techniques for botnets to hide their C2s, attacker only needs to selectively register a very small number of C2 domains, while for the defenders, it is difficult to determine in advance which domain names will be generated and registered.

Manjusaka: A Chinese sibling of Sliver and Cobalt Strike
Manjusaka: A Chinese sibling of Sliver and Cobalt Strike
  • Cisco Talos recently discovered a new attack framework called "Manjusaka" being used in the wild that has the potential to become prevalent across the threat landscape. This framework is advertised as an imitation of the Cobalt Strike framework. The implants for the new malware family are written in the Rust language for Windows and Linux. A fully functional version of the command and control (C2), written in GoLang with a User Interface in Simplified Chinese, is freely available and can generate new implants with custom configurations with ease, increasing the likelihood of wider adoption of this framework by malicious actors. We recently discovered a campaign in the wild using lure documents themed around COVID-19 and the Haixi Mongol and Tibetan Autonomous Prefecture, Qinghai Province. These maldocs ultimately led to the delivery of Cobalt Strike beacons on infected endpoints. We have observed the same threat actor using the Cobalt Strike beacon and implants from the Manjusaka framework.
