Weekly OSINT Highlights, 25 November 2024 (lien direct) |
## Snapshot
Last week\'s OSINT reporting reveals a persistent focus on sophisticated attacks targeting diverse sectors, from critical infrastructure to financial services and national defense. Attack types ranged from ransomware and phishing to cyberespionage and supply chain attacks, often leveraging advanced malware like LODEINFO, Asyncshell, and DEEPDATA. Threat vectors predominantly exploit unpatched vulnerabilities, malvertising, supply chain attacks, and credential harvesting, with phishing and social engineering remaining prominent tactics. Notable actors include APT groups such as Gelsemium and BrazenBamboo, alongside cybercriminal collectives like Ignoble Scorpius and Water Barghest, targeting organizations across the US, Europe, and Asia. The findings underscore the growing complexity of cyber threats, emphasizing the need for proactive threat intelligence and robust cybersecurity defenses.
## Description

## Snapshot
Last week\'s OSINT reporting highlights a complex landscape of cyber threats with a focus on APT groups, sophisticated malware, and exploitation of vulnerabilities. Many attacks are espionage-focused, with China-aligned groups like CeranaKeeper, Iran\'s Hazel Sandstorm, and Russia\'s Midnight Blizzard (SVR) leveraging spearphishing and vulnerability exploitation for intelligence gathering. Ransomware also remains a dominant attack type, with threat actors leveraging double extortion tactics to maximize pressure on victims. A surge in reporting on malware distribution was also observed, including Lua-based malware in the education sector and Pronsis Loader delivering Lumma Stealer. Additionally, multiple reports detail widespread campaigns leveraging phishing, malvertising, and cryptomining, with key targets being government institutions, financial services, and critical infrastructure. Attackers employ diverse techniques such as DNS tunneling, USB-based malware, and exploit known vulnerabilities like EternalBlue (CVE-2017-0144) and FortiOS (CVE-2024-23113).

CISO workshop slides (lien direct) |
A glossy, nicely-constructed and detailed PowerPoint slide deck by Microsoft Security caught my beady this morning. The title 'CISO Workshop: Security Program and Strategy' with 'Your Name Here' suggests it might be a template for use in a workshop/course bringing CISOs up to speed on the governance, strategic and architectural aspects of information security, but in fact given the amount of technical detail, it appears to be aimed at informing IT/technology managers about IT or cybersecurity, specifically. Maybe it is intended for newly-appointed CISOs or more junior managers who aspire to be CISOs, helping them clamber up the pyramid (slide 87 of 142): |

NICKEL - Targeting Organizations Across Europe, North America, and South America (lien direct) |
FortiGuard Labs is aware of reports relating to NICKEL, a state sponsored group targeting varying interests in Europe, North and South America. NICKEL is a state sponsored group operating out of China and is targeting governmental organizations, diplomatic groups and non governmental organizations in 29 countries.NICKELs' modus operandi is the usage of exploits on unpached systems to compromise vulnerable systems and their unpatched services. Observed exploits used by NICKEL included the exploitation of services such as Microsoft Exchange, Microsoft SharePoint, and Pulse Secure VPN. Microsoft filed pleadings with the United States District Court of Eastern Virginia on December 2nd to seize control of servers used by NICKEL.What are the Technical Details?NICKEL malware variants use Internet Explorer COM interfaces to receive instructions from predefined command and control (C2) servers. The malware will then connect to the web-based C2 servers to check for a specific string located on these servers. Once confirmed, the malware will decode a Base64 encoded blob that will load shellcode for further exploitation.NICKEL malware is capable of capturing system information such as the IP address, OS version, system language, computer name and username of the current signed in user. It also contains backdoor functionality to execute commands and to upload and download files. NICKEL then uses the stolen and compromised credentials of the targeted victim to login to Microsoft 365 accounts via browser logins to exfiltrate victim emails for further damage.What Other Names is NICKEL Known As?According to Microsoft - NICKEL is also known as APT15, APT25, and Ke3Chang.Is this Limited to Targeted Attacks?Yes. Attacks are limited to varying targets in specific countries and verticals.What Countries were Targeted?They are:Argentina, Barbados, Bosnia and Herzegovina, Brazil, Bulgaria, Chile, Colombia, Croatia, Czech Republic, Dominican Republic, Ecuador, El Salvador, France, Guatemala, Honduras, Hungary, Italy, Jamaica, Mali, Mexico, Montenegro, Panama, Peru, Portugal, Switzerland, Trinidad and Tobago, United Kingdom, United States of America, and Venezuela.What is the Status of Protections?FortiGuard Labs provides the following AV coverage used in this campaign as:W32/Staser.COFE!trW32/Staser.CBQX!trW32/NetE.VH!trW32/BackDoor.U!trAll network IOC's are blocked by the FortiGuard WebFiltering client.Any Other Suggested Mitigation?Because it has been reported that NICKEL obtains access via unpatched and vulnerable systems, It is important to ensure that all known vendor vulnerabilities are addressed and updated to protect from attackers having a foothold within a network. Attackers are well aware of the difficulty of patching and if it is determined that patching is not feasible at this time, an assessment should be conducted to determine risk.Also - organizations are encouraged to conduct ongoing training sessions to educate and inform personnel about the latest phishing/spear phishing attacks. They also need to encourage employees to never open attachments from someone they don't know, and to always treat emails from unrecognized/untrusted senders with caution. Since it has been reported that various phishing and spear phishing attacks have been delivered via social engineering distribution mechanisms, it is crucial that end users within an organization be made aware of the various types of attacks being delivered. This can be accomplished through regular training sessions and impromptu tests using predetermined templates by an organizations' internal security department. Simple user awareness training on how to spot emails with malicious attachments or links could also help prevent initial access into the network. |

NBlog Jan 22 - further lessons from Travelex (lien direct) |
At the bottom of a Travelex update on their incident, I spotted this yesterday:Customer PrecautionsBased on the public attention this incident has received, individuals may try to take advantage of it and attempt some common e-mail or telephone scams. Increased awareness and vigilance are key to detecting and preventing this type of activity. As a precaution, if you receive a call from someone claiming to be from Travelex that you are not expecting or you are unsure about the identity of a caller, you should end the call and call back on 0345 872 7627. If you have any questions or believe you have received a suspicious e-mail or telephone call, please do not hesitate to contact us. Although I am not personally aware of any such 'e-mail or telephone scams', Travelex would know better than me - and anyway even if there have been no scams as yet, the warning makes sense: there is indeed a known risk of scammers exploiting major, well-publicised incidents such as this. We've seen it before, such as fake charity scams taking advantage of the public reaction to natural disasters such as the New Orleans floods, and - who knows - maybe the Australian bushfires.At the same time, this infosec geek is idly wondering whether the Travelex warning message and web page are legitimate. It is conceivable that the cyber-criminals and hackers behind the ransomware incident may still have control of the Travelex domains, webservers and/or websites, perhaps all their corporate comms including the Travelex Twitter feeds and maybe even the switchboard behind that 0345 number. I'm waffling on about corporate identity theft, flowing on from the original incident.I appreciate the scenario I'm postulating seems unlikely but bear with me and my professional paranoia for a moment.
