It is crucial to protect yourself from cyber-attacks that can compromise your security posture and cause damage to your organization. With proper configurations and implementations, you can help prevent these cyber-attacks from impacting your organization. For each attack vector, we have compiled the top 3 recommendations for risk mitigation. Email Gateway Block unnecessary attachment file types – allow the minimum that is required for operating your organization. Enable aggressive anti-malware scanning such as advanced AV, Sandbox, or CDR. Enable URL scanning, sandboxing, and rewriting – in email body and attachments. Web Gateway Block downloads or allow the minimum required list of file types that is required for operating your organization. Block browsing categories that are not required for operating your organization. Focus on questionable categories such as “Newly Registered Domains,” “Parked Domains,” and “Uncategorized.” Implement browsing isolation to ensure th
Nao_sec identified an odd looking Word document in the wild, uploaded from an IP address in Belarus.This turned out to be a zero day vulnerability in Office and/or Windows.Defender for Endpoint missed execution.The document uses the Word remote template feature to retrieve a HTML file from a remote webserver, which in turn uses the ms-msdt MSProtocol URI scheme to load some code and execute some PowerShell.
ISO file downloads are advertised via QR codes on Twitter and on supposedly free gaming sites, but they don't contain what they promise.QR codes on Twitter and malvertisingThe loader for the malicious Chrome extension was initially analysed by @x3ph1 who dubbed it ChromeLoader.To avoid misunderstandings with legitimate Chrome components we hereby refer to it as Choziosi loader.The analysis on the loader is detailed but x3ph1 does not describe the Chrome extension Choziosi.Twitter user @th3_protoCOL found QR codes that circulate on Twitter and advertise pirated software to lure people into downloading an ISO.Reddit users also complain about malicious ISO files on websites that provide Steam games.This tweet by @StopMalvertisin says the ISOs are downloaded via malicious advertisements.hxxps://www.gdatasoftware.com/fileadmin/web/general/images/blog/2022/01/chromeloader_twitter2.pnghxxps://www.gdatasoftware.com/fileadmin/_processed_/7/1/chromeloader_reddit_c4998c051d.png
Cybersecurity researchers have disclosed details of the latest version of the Chaos ransomware line, dubbed Yashma.While it's purportedly a .NET version of Ryuk, closer examination of the sample reveals that it doesn't share much with the notorious ransomware. In fact, early versions of Chaos, which is now in its fourth iteration, were more akin to a destructive trojan than to traditional ransomware. Yashma version adds some new capabilities.
Check Point Research (CPR) details a targeted campaign that has been using sanctions-related baits to attack Russian defense institutes, part of the Rostec Corporation.The investigation shows that this campaign is part of a larger Chinese espionage operation that has been ongoing against Russian-related entities for several months.CPR researchers estimate with high confidence that the campaign has been carried out by an experienced and sophisticated Chinese nation-state APT.
PaloAlto Unit42 discovered a malicious HTML help file delivering Agent Tesla.The attack is interesting because attackers are often looking for creative ways to deliver their payloads.Their purpose in doing so is twofold:An attempt to bypass security products.An attempt to bypass security training.Potential victims may have been trained to avoid documents, scripts and executables from unknown senders, but it is important to be careful of almost any filetype.Agent Tesla is well-known malware that has been around for a while.Agent Tesla focuses on stealing sensitive information from a victim's computer and sending that information to the attacker over FTP, SMTP or HTTP.It does this primarily via keystroke logging, screen capturing, camera recording and accessing sensitive data.
A previously undocumented remote access trojan (RAT) written in the Go programming language has been spotted disproportionately targeting entities in Italy, Spain, and the U.K.Called Nerbian RAT by enterprise security firm Proofpoint, the novel malware leverages COVID-19-themed lures to propagate as part of a low volume email-borne phishing campaign.
In this attack analyzed by C25, the Chinese APT used a spear phishing email to deliver a beacon of a Red Team framework known as "Viper".The kill chain includes an artifact that is already known and that was attributed to Naikon one year ago and it is used to load and execute a custom shellcode.The target of this attack is currently unknown but with high probability, given the previous history of the attack perpetrated by the group, it might be a government institution from a South Asian country.
MITRE just published the 11 Strategies for a World-Class Cybersecurity Operations Center book. A recurring theme in this book is the importance of Cyber Threat Intelligence (CTI) as instrumental to “augment the SOC’s ability to identify adversaries and discern their movements from those of authorized users.” The document further states that CTI “moves the SOC from a per-incident approach to an adversary-focused paradigm.”As Cymulate XSPM is designed to provide extensive in-context CTI capabilities and, as such, supports each one of these tactics as briefly broached below.MITRE Strategy 1 - Know what you are protecting and why:XSPM provides a continuously updated situational awareness of the security posture of individual attack vectors, including iteratively observing, orienting, deciding, and acting through:the creation and continuous updater of a composite inventory of all exposed assets through attack surface management, the continuous security posture assessment through production-

One of Cymulates greatest features is the Purple Team module. It allows users to create advanced attack scenarios for Threat Hunting scenarios using templates which are the chained sum of the plethora of executions created by Cymulate. Bundled with the Immediate Threat Module, one can create strong Threat Hunting scenarios.But how does one create good threat hunting scenarios and really challenge ones Blue Team and test their capabilities?The Pyramid of Pain Let’s look at the pyramid of pain from a great article written way back in 2014.Designed back in 2013, as a response to the APT 1 report written by Mandiant. It was created as a response to the discussion about the report – people were talking mostly about the host-based indicators and the network-based indicators detection instead of leveraging the information describing the TTPs reported within the report.In short –Hash values – the computed hash values for malware and tools dropped in a compromise, these can be added into
The Iranian state-sponsored threat actor known as MuddyWater has been attributed to a new swarm of attacks targeting Turkey and the Arabian Peninsula with the goal of deploying remote access trojans (RATs) on compromised systems. "The MuddyWater supergroup is highly motivated and can use unauthorized access to conduct espionage, intellectual property theft, and deploy ransomware and destructive malware in an enterprise," Cisco Talos researchers Asheer Malhotra, Vitor Ventura, and Arnaud Zobec said in a report. The group, which has been active since at least 2017, is known for its attacks on various sectors that help further advance Iran's geopolitical and national security objectives.

🚨 TA416 Increases Operational Tempo Against European Governments as Conflict in Ukraine Escalates🚨News
Proofpoint researchers have observed TA416, an actor assessed to be aligned with the Chinese state, utilizing web bugs to profile their targets. Commonly referred to as tracking pixels, web bugs embed a hyperlinked non-visible object within the body of an email that, when enabled, will attempt to retrieve a benign image file from an actor-controlled server. This provides a "sign of life" to threat actors and indicates that the targeted account is valid with the user being inclined to open emails that utilize social engineering content. TA416 has been using web bugs to target victims prior to delivering malicious URLs that have installed a variety of PlugX malware payloads. The operational tempo of these campaigns, specifically those against European governments, have increased sharply since Russian troops began amassing on the border of Ukraine. The use of the web bug reconnaissance technique suggests TA416 is being more discerning about which targets the group chooses to deliver malwa
Avast Threat Research announced the discovery of new Golang ransomware, which they called HermeticRansom. This malware was found around the same time the HermeticWiper was found, and based on publicly available information from security community it was used in recent cyberattacks in Ukraine. The new ransomware was likely used as a smokescreen for the HermeticWiper attack due to its non-sophisticated style and poor implementation. Findings in a nutshell: Elections GoRansom (aka HermeticRansom) was used to target assets on the same day as HermeticWiper; The developers used a sarcastic function-naming scheme related to US presidential elections; The malware does not use any kind of obfuscation and has pretty straightforward functionality, suggesting it was created in a short amount of time.
New research by the Symantec Threat Hunter team, has uncovered a highly sophisticated piece of malware being used by China-linked threat actors, exhibiting technical complexity previously unseen by such actors. The malware appears to be used in a long-running espionage campaign against select governments and other critical infrastructure targets. There is strong evidence to suggest the malware, Backdoor.Daxin, which allows the attacker to perform various communications and data-gathering operations on the infected computer, has been used as recently as November 2021 by attackers linked to China. Most of the targets appear to be organizations and governments of strategic interest to China. In addition, other tools associated with Chinese espionage actors were found on some of the same computers where Daxin was deployed. Daxin is without doubt the most advanced piece of malware Symantec researchers have seen used by a China-linked actor. Considering its capabilities and the nature of its
Request smuggling and request concatenation in SAP NetWeaver, SAP Content Server and SAP Web Dispatcher (CVE-2022-22536)
On February 8th, SAP disclosed several vulnerabilities in the Internet Communication Manager (ICM), a critical component of its NetWeaver Application Servers. One critical vulnerability, named ICMAD (CVE-2022-22536), received a CVSS score of 10.0 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).A remote unauthenticated attacker could exploit this vulnerability by sending a simple HTTP request, and lead to a full system takeover and complete compromise of Confidentiality, Integrity and Availability of the system.While the best mitigation would be to patch the vulnerable servers as soon as possible, the following SAP Notes provide additional information around patch and mitigations:3123396 – [CVE-2022-22536] Request smuggling and request concatenation in SAP NetWeaver, SAP Content Server and SAP Web Dispatcher 3137885 – Workaround for security SAP note 3123396 3138881 – wdisp/additional_conn_close workaround for security SAP note 3123396The Cymulate team published an Advanced Scenario scanner allow
Lorenz is a ransomware strain, believed to be a rebranding of the ".sZ40" ransomware. Lorenz targets organizations worldwide with customized attacks demanding hundreds of thousands of dollars, and even millions in ransom fee. The group is targeting victims mostly in English-speaking countries, and according to their website, the group has published stolen data from more than 20 victims, although the estimated number of successful attacks is believed to be higher.
TA402, a likely Palestinian-aligned advance persistent threat actor, has recently engaged in campaigns leveraging a new implant, dubbed by Proofpoint analysts as NimbleMamba. NimbleMamba is likely a replacement for the group's previously used LastConn implant. These campaigns have a complex attack chain that leverages geofencing and URL redirects to legitimate sites in order to bypass detection efforts.
PrivateLoader is a modular downloader programmed in the C++ programming language connected to an unidentified PPI service. PrivateLoader sits at the front of this operation and communicates with its back-end infrastructure to retrieve URLs for the malicious payloads to "install" on the infected host. As is the case with downloaders tied to PPI services, PrivateLoader communicates a variety of statistics such as which payloads were downloaded and launched successfully. Distribution campaigns generally rely on a network of search engine optimization (SEO) enhanced websites that lure unsuspecting victims searching for warez aka pirated software to download and execute malware. A password-protected archive typically is delivered that contains a setup file that embeds and executes multiple malicious payloads on the infected host such as GCleaner, PrivateLoader, Raccoon, Redline, Smokeloader and Vidar malware.
