France warns of Nobelium cyberspies attacking French orgs

www.bleepingcomputer.com/news/security/france-warns-of-nobelium-cyberspies-attacking-french-orgs/ The French national cyber-security agency ANSSI said today that the Russian-backed Nobelium hacking group behind last year’s SolarWinds hack has been targeting French organizations since February 2021. While ANSSI (short for Agence Nationale de la Sécurité des Systèmes d’Information) has not determined how Nobelium compromised email accounts belonging to French orgs, it added that the hackers used them to deliver malicious emails targeting foreign institutions. The ANSSI report: www.cert.ssi.gouv.fr/cti/CERTFR-2021-CTI-011/

Russian hacking group uses new stealthy Ceeloader malware

www.bleepingcomputer.com/news/security/russian-hacking-group-uses-new-stealthy-ceeloader-malware/ The Nobelium hacking group continues to breach government and enterprise networks worldwide by targeting their cloud and managed service providers and using a new custom “Ceeloader” malware. Nobelium is Microsoft’s name for the threat actor behind last year’s SolarWinds supply-chain attack that led to the compromise of several US federal agencies. This group is believed to be the hacking division of the Russian Foreign Intelligence Service (SVR), commonly known as APT29, The Dukes, or Cozy Bear. The Mandiant report:


NICKEL targeting government organizations across Latin America and Europe

www.microsoft.com/security/blog/2021/12/06/nickel-targeting-government-organizations-across-latin-america-and-europe/ The Microsoft Threat Intelligence Center (MSTIC) has observed NICKEL, a China-based threat actor, targeting governments, diplomatic entities, and non-governmental organizations (NGOs) across Central and South America, the Caribbean, Europe, and North America. MSTIC has been tracking NICKEL since 2016 and observed some common activity with other actors known in the security community as APT15, APT25, and KeChang. Today, the Microsoft Digital Crimes Unit (DCU) announced the successful seizure of a set of NICKEL-operated websites and disruption of their ongoing attacks targeting organizations in 29 countries, following a court order from the U.S. District Court for the Eastern District of Virginia granting Microsoft the authority to seize these sites.

Cyber Command Publicly Joins Fight Against Ransomware Groups

threatpost.com/cyber-command-ransomware-groups/176801/ Cybercriminals who launch attacks on critical U.S. companies are going to be targeted by the branch of the military known as Cyber Command, and everyone has been put on notice. Gen. Paul Nakasone, who heads up Cyber Command, told the New York Times this weekend that his team isn’t just going after state actors, but that they’re taking on any cybercriminals who attack American infrastructure.

Magecart Groups Abuse Google Tag Manager

geminiadvisory.io/magecart-google-tag-manager/ Gemini analysts continue to identify Magecart campaigns that target numerous e-commerce sites worldwide. Since February 4, 2021, analysts have observed 316 e-commerce sites infected with trojanized Google Tag Manager (GTM) containers. This technique capitalizes on the ability to place JavaScript within the GTM container. Gemini has observed two variants that abuse GTM containers: one that embeds the malicious e-skimmer script in the container and another that uses the container to download the actual e-skimmer script from a separate dual-use domain. The abuse of this legitimate Google service is concerning because it provides threat actors free infrastructure upon which they can host their scripts, while also granting enhanced capability to avoid detection. The Magecart actors behind these attacks have posted at least 88, 000 payment card records from these attacks to the dark web markets.

Mirai-based Botnet – Moobot Targets Hikvision Vulnerability

www.fortinet.com/blog/threat-research/mirai-based-botnet-moobot-targets-hikvision-vulnerability Last September 18th, a threat researcher released a write-up about a remote code execution vulnerability that affects various products from Hikvision, one of the largest video surveillance brands in the world. Hikvision is a CVE CNA and quickly assigned the CVE number, CVE-2021-36260 and released a patch for the vulnerability on the same day as the threat researcher’s disclosure. During our analysis, we observed numerous payloads attempting to leverage this vulnerability to probing the status of devices or extracting sensitive data from victims. One payload in particular caught our attention. It tries to drop a downloader that exhibits infection behavior and that also executes Moobot, which is a DDoS botnet based on Mirai. In this blog we explain how an attacker delivers this payload through the Hikvision vulnerability, along with details of the botnet.

Yanluowang Ransomware Tied to Thieflock Threat Actor

threatpost.com/yanluowang-ransomware-thieflock-threat-actor/176640/ A threat actor previously tied to the Thieflock ransomware operation may now be using the emerging Yanluowang ransomware in a series of attacks against U.S. corporations, researchers have found. Researchers from Symantec, a division of Broadcom Software, found ties between Thieflock and Yanluowang, the latter of which they revealed in October after observing its use against a large organization.

Hakluke: Creating the Perfect Bug Bounty Automation

labs.detectify.com/2021/11/30/hakluke-creating-the-perfect-bug-bounty-automation/ I think I have a problem. I’m addicted to building bug bounty automation. I’ve built a full bug bounty automation framework from the ground up 3 times now. It has become better every time, but I’m still not happy. I’m about to start building my 4th iteration. Every time I build something I refine the process. In this article, I am going to walk you through every attempt I have made to build a bug bounty automation framework including the wins and failures. Then I’m going to tell you exactly how I plan to build my next one.

uBlock, I exfiltrate: exploiting ad blockers with CSS

portswigger.net/research/ublock-i-exfiltrate-exploiting-ad-blockers-with-css Ad blockers like uBlock Origin are extremely popular, and typically have access to every page a user visits. Behind the scenes, they’re powered by community-provided filter lists – CSS selectors that dictate which elements to block. These lists are not entirely trusted, so they’re constrained to prevent malicious rules from stealing user data. In this post, we’ll show you how we were able to bypass these restrictions in uBlock Origin, use a novel CSS-based exploitation technique to extract data from scripts and attributes, and even steal passwords from Microsoft Edge. All vulnerabilities discussed in this post have been reported to uBlock Origin and patched.

WebAssembly and Back Again: Fine-Grained Sandboxing in Firefox 95

hacks.mozilla.org/2021/12/webassembly-and-back-again-fine-grained-sandboxing-in-firefox-95/ In Firefox 95, we’re shipping a novel sandboxing technology called RLBox developed in collaboration with researchers at the University of California San Diego and the University of Texas that makes it easy and efficient to isolate subcomponents to make the browser more secure. This technique, which uses WebAssembly to isolate potentially-buggy code, builds on the prototype we shipped last year to Mac and Linux users. Now, we’re bringing that technology to all supported Firefox platforms (desktop and mobile), and isolating five different modules: Graphite, Hunspell, Ogg, Expat and Woff2.

Are You Guilty of These 8 Network-Security Bad Practices?

threatpost.com/bad-practices-network-security/176798/ The ongoing explosion of ransomware events and breaches (many of which the public never hears about) is elevating network security to a top corporate priority. Employees are constantly reminded to change their passwords frequently, watch out for phishing attacks and comply with strict security policies. But companies are also failing to address the everyday practices and mindsets that undermine traditional safeguards and increase the risk of a breach.

Public Wi-Fi Security: Is It Safe to Use for Business?

securityintelligence.com/articles/is-public-wi-fi-safe-business/ Let’s say you need to send an urgent email to a client while you’re at the store. Or, you’re traveling and need to take a Zoom call at your hotel. Maybe you need to access sensitive client data or employee information while on public Wi-Fi. You wonder how you should connect to the internet to do your task. The easiest and simplest thing to do is just pull out your phone and get the job done. But what about Wi-Fi security concerns?

Why the C-Suite Doesn’t Need Access to All Corporate Data

www.darkreading.com/vulnerabilities-threats/why-the-c-suite-doesn-t-need-access-to-all-corporate-data More than 20 months into a global pandemic, it’s become an article of faith that the best way to keep organizations and critical networks safe is to embrace zero trust. Under that umbrella, it’s assumed that all network access requests originate from an unsafe location, and every single user should be verified according to their locations, identities, and the health of their devices. But here’s the kicker: Zero-trust policies must apply to everyone even those at the top of the organizational chart, every CXO, director, and line-of-business leader. If C-level users do not need to access data to complete a task, they should not be granted access.
