2022-10-18 08:41:18 | The benefits of taking an intent-based approach to detecting Business Email Compromise (lien direct) |  By Abhishek Singh.BEC is a multi-stage attack. Adversaries first identify targets, then they establish rapport with the victim before exploiting them for whatever their end goal is. In the case of BEC, a threat actor can impersonate any employee in the organization to trick targets. A policy that checks for authorized email addresses of the sender can prevent BEC attacks. However, scaling the approach for every employee in a large organization is a challenge. Building an executive profile based on email analysis using a machine learning model and scanning emails against that profile will detect BEC. Data collection for building and training machine learning algorithms can take time, though, opening a window of opportunity for threat actors to exploit. Detection of exploitation techniques such as lookalike domains and any differences in the email addresses in the "From" and "Reply-to" fields can also detect BEC messages. However, the final verdict cannot account for the threat actor's intent. The intent-based approach detects BEC and then classifies it into the type of scam. It catches BEC messages, irrespective of whether a threat actor is impersonating a C-level executive or any employee in an organization. Classification based on the type of scam can help identify which segment of an organization was targeted and which employees were being impersonated by the threat actor. The additional information will further assist in better designing preventive features to stop BEC. Business email compromise (BEC) is one of the most financially damaging online crimes. As per the internet crime 221 report, the total loss in 2021 due to BEC is around 2.4 billion dollars. Since 2013, BEC has resulted in a 43 billion dollars loss. The report defines BEC as a scam targeting businesses (not individuals) working with foreign suppliers and companies regularly performing wire transfer payments. Fraudsters carry out these sophisticated scams to conduct the unauthorized transfer of funds. This introduces the challenge of how to detect and block these campaigns as they continue to compromise organizations successfully. There are a variety of approaches to identifying BEC email messages, such as using policy to allow emails from authorized email addresses, detecting exploitation techniques used by threat actors, building profiles by analysis of emails, and validating against the profile to detect BEC. These approaches have a variety of limitations or shortcomings. Cisco Talos is taking a different approach and using an intent-based model to identify and block BEC messages. Before we get too deep into the intent-based model, take a deeper look at the commonly used approaches to block BEC from the simplistic through machine learning (ML) approaches. Policy-based detection The first place to start is with policy-based detection as it is one of the most common and simplistic approaches to blocking BEC campaigns. Let's start by looking at an example of a BEC email. |

Hacker Pwns Uber Via Compromised VPN Account
(published: September 16, 2022)
On September 15, 2022, ride-sharing giant Uber started an incident response after discovering a data breach. According to Group-IB researchers, download file name artifacts point to the attacker getting access to fresh keylogger logs affecting two Uber employees from Indonesia and Brazil that have been infected with Racoon and Vidar stealers. The attacker allegedly used a compromised VPN account credentials and performed multifactor authentication fatigue attack by requesting the MFA push notification many times and then making a social-engineering call to the affected employee. Once inside, the attacker allegedly found valid credentials for privilege escalation: a PowerShell script containing hardcoded credentials for a Thycotic privileged access management admin account. On September 18, 2022, Rockstar Games’ Grand Theft Auto 6 suffered a confirmed data leak, likely caused by the same attacker.
Analyst Comment: Network defenders can consider setting up alerts for signs of an MFA fatigue attack such as a large number of MFA requests in a relatively short period of time. Review your source code for embedded credentials, especially those with administrative privileges.

2022-08-18 08:00:00 | Ukraine and the fragility of agriculture security (lien direct) |  By Joe Marshall.The war in Ukraine has had far-reaching global implications and one of the most immediate effects felt will be on the global supply chain for food. This war-induced fragility has exposed the weaknesses of how we feed ourselves globally. Ransomware cartels and other adversaries are well aware of this and are actively exploiting that fragility. For the past six years, Cisco Talos has been actively involved in assisting public and private institutions in Ukraine to defend themselves against state-sponsored actors. Our involvement stretches the gamut from commercial to critical infrastructure, to election security. Our presence has afforded us unique opportunities and observations about cybersecurity in a macro and micro way. Ukraine has been a frequent victim of state-sponsored cyber attacks aimed at critical infrastructures like power and transportation. Talos is proud to stand with our partners in Ukraine and help defend their critical networks and help users there maintain access to necessary services. Now that Russia has invaded Ukraine, those threats have escalated to kinetic attacks that are wreaking havoc on a critical element of our world: agriculture and our global food supply chain. Even worse is the implications this war will have for future cyber attacks, as fragility is considered a lucrative element in deciding victimology by threat actors like ransomware cartels. To truly grasp the implications of the war in Ukraine, we have to examine how vital Ukrainian agriculture feeds the world, the current state of affairs, and what this means for the global cybersecurity posture to protect agricultural assets. Where there is weakness, there is opportunityRansomware cartels and their affiliates are actively targeting the agricultural industry. Moreover, these actors have done their homework and are targeting agricultural companies during the two times of the year where they cannot suffer disruptions: planting and harvesting. Per the published FBI PIN Alert: “Cyber actors may perceive cooperatives as lucrative targets with a willingness to pay due to the time-sensitive role they play in agricultural production.” This is far from unusual for these adversaries - they are shrewd and calculating, and understand their victims' weaknesses and industries.

The operators of the service also established Discord and Telegram communities where they provide technical support and assistance for customers on the platform.  Dark Utilities provides payloads consisting of code that is executed on victim systems, allowing them to be registered with the service and establish a command and control (C2) communications channel. The platform currently supports Windows, Linux and Python-based payloads, allowing adversaries to target multiple architectures without requiring significant development resources. During our analysis, we observed efforts underway to expand OS and system architecture support as the platform continues to see ongoing develo |

2022-08-02 08:00:14 | Manjusaka: A Chinese sibling of Sliver and Cobalt Strike (lien direct) |  By Asheer Malhotra and Vitor Ventura.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.IntroductionCisco Talos has discovered a relatively new attack framework called "Manjusaka" (which can be translated to "cow flower" from the Simplified Chinese writing) by their authors, being used in the wild.As defenders, it is important to keep track of offensive frameworks such as Cobalt Strike and Sliver so that enterprises can effectively defend against attacks employing these tools. Although we haven't observed widespread usage of this framework in the wild, it has the potential to be adopted by threat actors all over the world. This disclosure from Talos intends to provide early notification of the usage of Manjusaka. We also detail the framework's capabilities and the campaign that led to the discovery of this attack framework in the wild.The research started with a malicious Microsoft Word document (maldoc) that contained a Cobalt Strike (CS) beacon. The lure on this document mentioned a COVID-19 outbreak in Golmud City, one of the largest cities in the Haixi Mongol and Tibetan Autonomous Prefecture, Qinghai Province. During the investigation, Cisco Talos found no direct link between the campaign and the framework developers, aside from the usage of the framework (which is freely available on GitHub). However, we could not find any data that could support victimology definition. This is justifiable considering there's a low number of victims, indicating the early stages of the campaign, further supported by the maldoc metadata that indicates it was created in the second half of June 2022.While investigating the maldoc infection chain, we found an implant used to instrument Manjusaka infections, contacting the same IP address as the CS beacon. This implant is written in the Rust programming language and we found samples for Windows and Linux operating systems. The Windows implant included test samples, which had non-internet-routable IP addresses as command and control (C2). Talos also discovered the Manjusaka C2 executable - a fully functional C2 ELF binary written in GoLang with a User Interface in Simplified Chinese - on GitHub. While analyzing the C2, we generated implants by specifying our configurations. The developer advertises it has an advers |

Kindly allow me to elaborate ... errrr ..."'Online safety' sounds vaguely on-topic for us and our clients, so having tripped over a mention of this, I went Googling for more information. First stop: the latest amended version of the Online Safety Bill. It is written in extreme legalese, peppered with strange terms defined in excruciating detail, and littered with internal and external cross-references, hardly any of which are hyperlinked e.g. | Guideline | APT 10 | |

Having recently blogged about the dreaded SoA, 'nuff said on that.Today I'm picking up on the SoA's shy little brother, the Risk Treatment Plan. There's a lot to say and think about here, so coffee-up, settle-down, sit forward and zone-in.ISO/IEC 27001 barely even acknowledges the RTP. Here are the first two mentions, tucked discreetly under clause 6.1.3: |

Credit Card Stealer Targets PsiGate Payment Gateway Software
(published: May 25, 2022)
Sucuri Researchers have detailed their findings on a MageCart skimmer that had been discovered within the Magento payment portal. Embedded within the core_config_data table of Magento’s database, the skimmer was obfuscated and encoded with CharCode. Once deobfuscated, a JavaScript credit card stealer was revealed. The stealer is able to acquire text and fields that are submitted to the payment page, including credit card numbers and expiry dates. Once stolen, a synchronous AJAX is used to exfiltrate the data.
Analyst Comment: Harden endpoint security and utilize firewalls to block suspicious activity to help mitigate against skimmer injection. Monitor network traffic to identify anomalous behavior that may indicate C2 activity.

How the Saitama Backdoor uses DNS Tunneling
(published: May 25, 2022)
MalwareBytes Researchers have released their report detailing the process behind which the Saitama backdoor utilizes DNS tunneling to stealthy communicate with command and control (C2) infrastructure. DNS tunneling is an effective way to hide C2 communication as DNS traffic serves a vital function in modern day internet communications thus blocking DNS traffic is almost never done. Saitama formats its DNS lookups with the structure of a domain consisting of message, counter . root domain. Data is encoded utilizing a hardcoded base36 alphabet. There are four types of messages that Saitama can send using this method: Make Contact to establish communication with a C2 domain, Ask For Command to get the expected size of the payload to be delivered, Get A Command in which Saitama will make Receive requests to retrieve payloads and instructions and finally Run The Command in which Saitama runs the instructions or executes the payload and sends the results to the established C2.
Analyst Comment: Implement an effective DNS filtering system to block malicious queries. Furthermore, maintaining a whitelist of allowed applications for installation will assist in preventing malware like Saitama from being installed.
