2023-02-20 03:21:02 | How do mail filters work? (lien direct) | Mail filters play a huge role in protecting organizations from cyberattacks. Even though their task is quite small, they are very important for an organization's ability to deter many malicious phishing and spam emails before delivery to a person's inbox. According to the IBM X-Force Threat Intelligence Index, 40% of attacks in the manufacturing industry are phishing attacks, and 1 in 3 employees are most likely to fall for a phishing scam. How do mail filters work? Email SPAM filters use a variety of techniques to protect mail delivery. A mail filter will take action, such as rejecting... | Spam Threat | ★★ | |

[Scam of the Week] The Turkey-Syria Earthquake
Just when you think they cannot sink any lower, criminal internet scum is now exploiting the recent earthquake in Turkey and Syria.
Less than 24 hours after two massive earthquakes claimed the lives of tens of thousands of people, cybercrooks are already piggybacking on the horrible humanitarian crisis. You need to alert your employees, friends and family... again.
Just one example are scammers that pose as representatives from a Ukrainian charity foundation that seeks money to help those affected by the natural disasters that struck in the early hours of Monday.
There are going to be a raft of scams varying from blood drives to pleas for charitable contributions for victims and their families. Unfortunately, this type of scam is the worst kind of phishbait, and it is a very good idea to inoculate people before they get suckered into falling for a scam like this.
I suggest you send the following short alert to as many people as you can. As usual, feel free to edit:
[ALERT] "Lowlife internet scum is trying to benefit from the Turkey-Syria earthquake. The first phishing campaigns have already been sent and more will be coming that try to trick you into clicking on a variety of links about blood drives, charitable donations, or "exclusive" videos.
"Don't let them shock you into clicking on anything, or open possibly dangerous attachments you did not ask for! Anything you receive about this recent earthquake, be very suspicious. With this topic, think three times before you click. It is very possible that it is a scam, even though it might look legit or was forwarded to you by a friend -- be especially careful when it seems to come from someone you know through email, a text or social media postings because their account may be hacked.
"In case you want to donate to charity, go to your usual charity by typing their name in the address bar of your browser and do not click on a link in any email. Remember, these precautions are just as important at the house as in the office, so tell your friends and family."
It is unfortunate that we continue to have to warn against the bad actors on the internet that use these tragedies for their own benefit. For KnowBe4 customers, we have a few templates with this topic in the Current Events. It's a good idea to send one to your users this week.

2023-02-08 21:15:10 | CVE-2023-25163 (lien direct) | Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. All versions of Argo CD starting with v2.6.0-rc1 have an output sanitization bug which leaks repository access credentials in error messages. These error messages are visible to the user, and they are logged. The error message is visible when a user attempts to create or update an Application via the Argo CD API (and therefor the UI or CLI). The user must have `applications, create` or `applications, update` RBAC access to reach the code which may produce the error. The user is not guaranteed to be able to trigger the error message. They may attempt to spam the API with requests to trigger a rate limit error from the upstream repository. If the user has `repositories, update` access, they may edit an existing repository to introduce a URL typo or otherwise force an error message. But if they have that level of access, they are probably intended to have access to the credentials anyway. A patch for this vulnerability has been released in version 2.6.1. Users are advised to upgrade. There are no known workarounds for this vulnerability. | Spam Tool Vulnerability | Uber | |

2023-01-13 19:15:12 | CVE-2023-22489 (lien direct) | Flarum is a discussion platform for websites. If the first post of a discussion is permanently deleted but the discussion stays visible, any actor who can view the discussion is able to create a new reply via the REST API, no matter the reply permission or lock status. This includes users that don't have a validated email. Guests cannot successfully create a reply because the API will fail with a 500 error when the user ID 0 is inserted into the database. This happens because when the first post of a discussion is permanently deleted, the `first_post_id` attribute of the discussion becomes `null` which causes access control to be skipped for all new replies. Flarum automatically makes discussions with zero comments invisible so an additional condition for this vulnerability is that the discussion must have at least one approved reply so that `discussions.comment_count` is still above zero after the post deletion. This can open the discussion to uncontrolled spam or just unintentional replies if users still had their tab open before the vulnerable discussion was locked and then post a reply when they shouldn't be able to. In combination with the email notification settings, this could also be used as a way to send unsolicited emails. Versions between `v1.3.0` and `v1.6.3` are impacted. The vulnerability has been fixed and published as flarum/core v1.6.3. All communities running Flarum should upgrade as soon as possible. There are no known workarounds. | Spam Vulnerability | ||

Chinese Gambling Spam Targets World Cup Keywords
(published: December 2, 2022)
Since 2018, a large-scale website infection campaign was affecting up to over 100,000 sites at a given moment. Infected websites, mostly oriented at audiences in China, were modified with additional scripts. Compromised websites were made to redirect users to Chinese gambling sites. Title and Meta tags on the compromised websites were changed to display keywords that the attackers had chosen to abuse search engine optimization (SEO). At the same time, additional scripts were switching the page titles back to the original if the visitor fingerprinting did not show a Chinese search engine from a preset list (such as Baidu).
Analyst Comment: Website owners should keep their systems updated, use unique strong passwords and introduce MFA for all privileged or internet facing resources, and employ server-side scanning to detect unauthorized malicious content. Implement secure storage for website backups.

Leaked Android Platform Certificates Create Risks for Users
(published: December 2, 2022)
On November 30, 2022, Google reported 10 different Android platform certificates that were seen actively abused in the wild to sign malware. Rapid7 researchers found that the reported signed samples are adware, so it is possible that these platform certificates may have been widely available. It is not shared how these platform certificates could have been leaked.
Analyst Comment: Malware signed with a platform certificate can enjoy privileged execution with system permissions, including permissions to access user data. Developers should minimize the number of applications requiring a platform certificate signature.

Massive ois[.]is Black Hat Redirect Malware Campaign
(published: November 9, 2022)
Since September 2022, a new WordPress malware redirects website visitors via ois[.]is. To conceal itself from administrators, the redirect will not occur if the wordpress_logged_in cookie is present, or if the current page is wp-login.php. The malware infects .php files it finds – on average over 100 files infected per website. A .png image file is initiating a redirect using the window.location.href function to redirect to a Google search result URL of a spam domain of actors’ choice. Sucuri researchers estimate 15,000 affected websites that were redirecting visitors to fake Q&A sites.
Analyst Comment: WordPress site administrators should keep their systems updated and secure the wp-admin administrator panel with 2FA or other access restrictions. If your site was infected, perform a core file integrity check, query for any files containing the same injection, and check any recently modified or added files.

The archive file is "US midterm elections The six races that could decide the US Senate.zip" that has a link file with the same name, which leads to Emotet.Why is this Significant?This is significant because Emotet is trying to leverage the interest of the U.S. midterm elections for infection. While FortiGuard Labs has not observed the infection vector, the file name "US midterm elections The six races that could decide the US Senate.zip" was likely distributed via emails. "The six races" likely refers to Arizona, Georgia, Michigan, Nevada, Pennsylvania, and Wisconsin where Democrats and Republican are expected to have close race in the elections, which gives better chance that recipients will open the archive contents. Emotets' modus operandi includes distribution via malicious spam campaigns and thread hijacking of emails.What's in "US midterm elections The six races that could decide the US Senate.zip"?The zip file contains a link file named "US midterm elections The six races that could decide the US Senate.lnk".

2022-10-27 10:00:00 | 11 Cybersecurity investments you can make right now (lien direct) | This blog was written by an independent guest blogger. The average cost of a data breach will continue to rise, which means companies need to start planning accordingly. To protect your business, you need to invest in cybersecurity. Here are 11 areas you should focus on. Cyber insurance Cyber insurance is designed to protect businesses from the financial repercussions of a cyber-attack. It can cover costs such as business interruption, data recovery, legal expenses, and reputational damage. It is increasingly common across industries and at companies of all sizes, even small businesses, which have become a growing target of cybercriminals. Cyber insurance has also become a new compliance requirement in many industries, including healthcare, finance, and retail. In the event of a data breach, companies are often required to notify their customers and partners, which can be costly. Cyber insurance can help cover these expenses. Employee training Employees are often the weakest link in a company's cybersecurity defenses. They may not be aware of the latest cyber threats or how to protect themselves from them. That's why it's important to provide employees with regular training on cybersecurity risks and best practices. There are many different types of employee training programs available, ranging from in-person seminars to online courses. Some companies even offer financial incentives for employees who complete training programs. In the remote work era, employee education also increasingly means arming remote workers with knowledge that will keep company data safe while they are working on networks that might not be well secured. This is especially the case if you know people are connecting via public networks at cafes, co-working spaces, and airports. Endpoint security Endpoints are the devices that connect to a network, such as laptops, smartphones, and tablets. They are also a common entry point for cyber-attacks. That's why it's important to invest in endpoint security, which includes solutions such as antivirus software, firewalls, and encryption. You can invest in endpoint security by purchasing it from a vendor or by implementing it yourself. There are also many free and open-source solutions available. Make sure you test any endpoint security solution before deploying it in your environment. Identity and access management Identity and access management (IAM) is a process for managing user identities and permissions. It can be used to control who has access to what data and resources, and how they can use them. IAM solutions often include features such as Single Sign-On (SSO), which allows users to access multiple applications with one set of credentials, and two-factor authentication (2FA), which adds an extra layer of security. IAM solutions can be deployed on-premises or in the cloud. They can also be integrated with other security solutions, such as firewalls and intrusion detection systems. Intrusion detection and prevention Intrusion detection and prevention systems (IDPS) are designed to detect and prevent cyber-attacks. They work by monitoring network traffic for suspicious activity and blocking or flagging it as needed. IDPS solutions can be deployed on-premises or in the cloud. There are many different types of IDPS solutions available, ranging from simple network-based solutions to more sophisticated host-based ones. Make sure you choose a solution that is right for your environment and needs.

2022-10-20 13:36:00 | Threat Hunting: Eight Tactics to Accelerating Threat Hunting (lien direct) | One of the more significant headaches in cyber security is the overuse of buzzwords and acronyms and the overlapping mutations of what they mean. Cyber threat Hunting has become one of those phrases, but it has gained clarity over the last few years as organizations strived to become more proactive. So what is threat hunting? Depending on who you ask, you may get somewhat different answers to the same question. Cyber threat hunting is a proactive approach to detecting suspicious activity from known or unknown, remediated, or unaddressed cyber threats within an organization’s networks. It involves finding malware such as viruses, Trojans, adware, spyware, ransomware, worms, bots, and botnets. The goal is for security analysts to find these threats before they cause damage to systems and data. It’s similar to how fire departments respond to fires; they go into buildings to ensure no additional problems before calling the firefighters. There is a vast collection of tools, skill sets, approaches, and processes to help identify advanced threats that could happen within the network. What is an effective hunting process for one organization may be a waste of time for another, depending on each company’s understanding of what threats they might face. Man-hours spent hunting are typically most beneficial for large organizations targeted by the cybercriminal community regularly, but that’s not to say that regular hunts for small/medium-sized enterprises can’t benefit from and identify threats by doing the same. Structured Threat Hunting The structured hunt is based on indicators of compromise (IOCs) and tactics, techniques, and procedures (TTP). IOCs provide information about potential adversaries, such as IP addresses, domain names, operating system versions, etc. TTPs describe how attackers operate and what tools they use. Combining IOCs and TTPs makes it possible to build a picture of the adversary. This approach allows us to detect threats earlier and prevent attacks. In addition, we can quickly identify the threat actors because each activity is described in detail. Unstructured Threat Hunting The concept of unstructured hunting is relatively new. It wasn’t until 2013 that we began seeing the emergence of unstructured hunters. Unstructured hunting is a method of finding malicious software (malware), such as viruses, Trojans, worms, etc., without knowing exactly what type of malware you are looking for. Instead, the hunter relies on behavioral analysis to find these threats. In short, unstructured hunting is investigative work where a cyber threat hunter observes behavior and looks for anomalies. For example, if someone sends out spam emails, a system administrator might notice unusual activity on his network and investigate further. If he finds something suspicious, he could take action immediately or wait a few days to see if the same email addresses start sending again. Traditional Threat Hunting The traditional definition of threat hunting can be defined as a focused and intensive human/machine-assisted process aimed to identify the possibility of something malicious happening within the network or likely about to happen; this is based on abnormal network behavior, artifacts, or identification via active threat research. A good example of this would be: A large bank has team members whose part of their job is to consume threat reports related to activity targeting their vertical and other companies that match their Enterprise profile. > A new threat report is published from an intel provider describing a new variant of malware that has been catastrophic at similar organizations. This report would ideally contain information around the process tree, registry key, etc., to help the cyber threat hunters not just hunt for detection of the associated IOCs but dig deeper to identify patterns that match the behavior of the malware across the network, like abnormal PowerShell executio | Spam Malware Tool Vulnerability Threat | ||

2022-10-17 10:00:00 | Stories from the SOC: Feeling so foolish – SocGholish drive by compromise (lien direct) | Executive summary:
SocGholish, also known as FakeUpdate, is a JavaScript framework leveraged in social engineering drive by compromises that has been a thorn in cybersecurity professionals’ and organizations’ sides for at least 5 years now. Upon visiting a compromised website, users are redirected to a page for a browser update and a zip archive file containing a malicious JavaScript file is downloaded and unfortunately often opened and executed by the fooled end user.
An AT&T Managed Extended Detection and Response (MXDR) client with Managed Endpoint Security (MES) powered by SentinelOne (S1) received an alert regarding the detection and mitigation of one of these JavaScript files. The MXDR Threat Hunter assigned to this client walked them through the activity resulting from the execution of the malicious file, as well as provide additional guidance on containment and remediation of the host involved in the incident.
Investigation
Upon detection of the follow up activity of the malicious file executed by the end user, S1 created an Incident within the S1 portal. This in turn creates an Alarm within the USM Anywhere platform, where the MXDR SOC team works, reviews, and creates Investigations for client notification as necessary. Since this activity was observed all within S1, this analysis will be out of there.
The best way to start looking into a S1 event is to go to the Storyline of the Incident within Deep Visibility.
Once we have all the events related to the Incident, we can also create a new Deep Visibility search for all activity related to the affected host from about an hour before right up to the first event for the incident. This will let us try to see what happened on the host that lead to the execution of the malicious JavaScript file.
Reviewing the events from both the overall logs on the host and the events related to the Storyline, we can build out a rough timeline of events. Note there are close to 15k events on the host in the timeframe and 448 events in total in the Storyline; I’m just going over the interesting findings for expediency sake.
12:07:08 The user is surfing on Chrome and using Google search to look up electricity construction related companies; we see two sites being visited, with both sites being powered by WordPress. The SocGholish campaign works by injecting malicious code into vulnerable WordPress websites. While I was unable to find the injected code within the potentially compromised sites, I see that one of the banners on the page contains spam messages; while there are no links or anything specifically malicious with this, it lets us know that this site is unsafe to a degree.

We can assume the URI for the request looks like the /report as seen in VirusTotal and described in open-source intelligence (OSI). Note that the subdomain “clean” has a different resolution than the root domain; this is domain shadowing performed by the attackers by creating a new A-record within the DNS settings of the legitimate domain:

2022-10-14 01:24:52 | Guloader Spam Indiscriminately Sent to State Elections Board (lien direct) | Recently, the United States Federal Bureau of Investigation (FBI) and the Cybersecurity and Infrastructure Security Agency (CISA) issued a joint public service announcement - Foreign Actors Likely to Use Information Manipulation Tactics for 2022 Midterm Elections (9I-100622-PSA). The focus of the PSA was to inform the public of the potential manipulation of the midterm election cycle in the United States by foreign agents using social engineering and social media disinformation tactics to influence voters and to sow discord as well.Around the same time of the announcement, FortiGuard Labs observed a Guloader campaign being sent to an elections body in the United States. Although there is no sign that they were specifically targeted, we want to highlight what's involved in these attacks given the 2022 U.S. midterm elections in November. The infection vectors are simple malicious spam that do not rely on exploiting a vulnerability or macros.FortiGuard Labs found a campaign from a purported industrial equipment manufacturer in Indonesia, containing a malicious ISO attachment. Figure 1. Email used in this spam campaignISO email attachments are often used to avoid detection by security solutions. Clicking on the attachment triggers the ISO file. Once mounted, an EXE file-a GuLoader malware variant-becomes visible. The victim then needs to run the "Requisition order-PT. LFC Teknologi,pdf.exe" executable manually to start the infection routine. Figure 2. GuLoader file in the mounted ISO fileThis file is digitally signed via an untrusted root certificate, seen below.Figure 3. Digital signature information for "Requisition order-PT. LFC Teknologi,pdf.exe".The GuLoader payload is a so-called first stage malware that has been seen in the wild for the past few years. It is designed to deliver a second stage payload that can be tailored to the attacker's liking. Some reported second stage payloads include Remote Access Trojans (RATs), infostealers, and ransomware.This particular GuLoader variant reaches out to 195[.]178[.]120[.]184/sMHxAbMCsvl181[.]java, which was no longer available at the time of the investigation. However, we believe the java file to either be a decryption key or a payload download. Another, GuLoader sample (SHA2: 46f8a8cec6bb92708a185cfea876ea1ae0cdef2321dc50f140f23c7cc650b65e) was submitted to VirusTotal on September 14th. This sample accesses 195[.]178[.]120[.]184/uFLBwGvx55[.]java and available OSINT suggests that the payload is the Azorult infostealer. Azorult is capable of exfiltrating data such as passwords from browsers, email, and FTP servers, and harvesting files with extensions specified by an attacker. It can also collect machine information such as user and computer name, installed programs, Windows version, and installed programs. Such stolen information can be a precursor to future attacks.Based on the traits of the GuLoader sample, FortiGuard Labs tracked down additional files involved in the same malicious spam campaign. The attacker mostly used IMG and ISO attachments along with file names in English, German, Spanish, Turkish, and Chinese. Taking a look at VirusTotal, submissions of the attachments are from the US, Czechia, China, Turkey, Germany, UK, Israel, Ireland, and Hungary. The GuLoader variant was also submitted to VirusTotal from the US, Bulgaria, Canada, China, the United Arab Emirates, and Korea. The email delivered to a board of elections in the United States was sent to a publicly available webmaster address. This indicates that the attacker sent these malicious emails to as many recipients as possible in the hope that someone would manually execute the malware. This is the first step to a potential compromise of machines related to the elections board of this United States state, and will allow the attacker to obtain a foothold to obtain unauthorized data for dissemination or simply various angles of disruption (ransomware, wiping, extortion, etc.) and even worse, perhaps sell access to an adversary for financial gain.Fortinet ProtectionsFortinet customers are already protected fr | Spam Malware Vulnerability | ||

2022-10-12 10:00:00 | 12 Essential ways to improve your website security (lien direct) | This blog was written by an independent guest blogger. In today's digital age, a business website is essential for success. Not only does it provide potential customers with information about your products or services, but it also allows you to connect and engage with them directly. However, simply having a website is not enough. To ensure that your site is effective and safe, you need to make sure that it has all the necessary security features. In this article, we will discuss twelve security features that every business website must have. 1. Auto-update enabled for plugins and software One of the simplest but most effective security measures you can take, especially if you’re looking to protect your WordPress site, is to ensure that all your plugins and software are up-to-date. Outdated software is one of the most common ways that attackers gain access to websites. By keeping everything up to date, you can help to prevent vulnerabilities from being exploited. You can usually enable auto-updates for most plugins and software from within their setting's menus. For WordPress sites, there is also a plugin called Easy Updates Manager that can help you to keep everything up to date with ease. 2. A strong password policy A strong password policy is the first step to protecting your website from malicious actors. By requiring strong and unique passwords, you can make it significantly more difficult for attackers to gain access to your site. You need to ensure that your website's backend is well protected and that only authorized users have access. To do this, you should consider using a password manager to generate and store strong passwords for your site. You definitely should not be using the same password for multiple sites. 3. Two-factor authentication Two-factor authentication (2FA) is an important security measure that you should consider implementing for your website. 2FA adds an extra layer of security by requiring users to provide two pieces of information before they can access your site. This could include a password and a one-time code that is generated by an app on your phone. 2FA can help to prevent attackers from gaining access to your site, even if they have your password. 4. A secure socket layer (SSL) certificate An SSL certificate is a must-have for any website that wants to protect their users' information. SSL encrypts the communications between your website and your users' web browsers. This means that even if an attacker was able to intercept the communication, they would not be able to read it. SSL also provides authentication, which means you can be sure that your users are communicating with the intended website and not a fake site set up by an attacker. Increasingly, having things like HTTPS and an SSL certificate are part of Google's ranking metrics and will help your website's SEO. If you aren't making an effort to protect your visitors and users (the people who give you their sensitive credit card information), they may take their business elsewhere. 5. A web application firewall (WAF) A web application firewall (WAF) is a piece of software that sits between your website and the internet. It filters traffic to your site and blocks any requests that it considers to be malicious. WAFs can be very effective at stopping attacks such as SQL injection and cross-site scripting (XSS). 6.

A Multimillion Dollar Global Online Credit Card Scam Uncovered
(published: September 23, 2022)
ReasonLabs researchers discovered a large network of fake dating and customer support websites involved in credit card fraud operations. The threat actor builds a basic website, registers it with a payment processor (RocketGate), buys credit card data from other threat actors, and subscribes victims to monthly charging plans. The US was the most targeted, and a lower number of sites were targeting France. To pass the processor checks and lower the number of charge-backs the actor avoided test charges, used a generic billing name, charged only a small, typical for the industry payment, and hired a legitimate support center provider, providing effortless canceling and returning of the payment.
Analyst Comment: Users are advised to regularly check their bank statements and dispute fraudulent charges. Researchers can identify a fraudulent website by overwhelming dominance of direct-traffic visitors from a single country, small network of fake profiles, and physical address typed on a picture to avoid indexing.

Malicious OAuth Applications Used to Compromise Email Servers and Spread Spam
(published: September 22, 2022)
Microsoft researchers described a relatively stealthy abuse of a compromised Exchange server used to send fraud spam emails. After using valid credentials to get access, the actor deployed a malicious OAuth application, gave it admin privileges and used it to change Exchange settings. The first modification created a new inbound connector allowing mails from certain actor IPs to flow through the victim’s Exchange server and look like they originated from the compromised Exchange domain. Second, 12 new transport rules were set to delete certain anti-spam email headers.
Analyst Comment: If you manage an Exchange server, strengthen account credentials and enable multifactor authentication. Investigate if receiving alerts regarding suspicious email sending and removal of antispam header.

This is likely due to several factors, including the closure of several ransomware groups, whether it be of their own volition or the actions of global law enforcement agencies and governments.  Commodity malware was the top observed threat this quarter, a notable development given the general decrease in observations of attacks leveraging commodity trojans in CTIR engagements since 2020. These developments coincide with a general resurgence of certain email-based trojans in recent months, as law enforcement and technology companies have continued to attempt to disrupt and affect email-based malware threats like Emotet and Trickbot. This quarter featured malware such as the Remcos remote access trojan (RAT), Vidar infostealer, Redline Stealer and Qakbot (Qbot), a well-known banking trojan that in recent weeks, has been observed in new clusters of activity delivering a variety of payloads. TargetingThe top-targeted vertical continues to be telecommunications, following a trend where it was among the top targeted verticals in Q4 2021 and Q1 2022, closely followed by organizations in the education and health care sectors.
