2023-03-06 19:15:10 | CVE-2023-23939 (lien direct) | Azure/setup-kubectl is a GitHub Action for installing Kubectl. This vulnerability only impacts versions before version 3. An insecure temporary creation of a file allows other actors on the Actions runner to replace the Kubectl binary created by this action because it is world writable. This Kubectl tool installer runs `fs.chmodSync(kubectlPath, 777)` to set permissions on the Kubectl binary, however, this allows any local user to replace the Kubectl binary. This allows privilege escalation to the user that can also run kubectl, most likely root. This attack is only possible if an attacker somehow breached the GitHub actions runner or if a user is utilizing an Action that maliciously executes this attack. This has been fixed and released in all versions `v3` and later. 775 permissions are used instead. Users are advised to upgrade. There are no known workarounds for this issue. | Tool Vulnerability | ||

2023-03-06 11:00:00 | What is firewall optimization? (lien direct) | Firewall optimization (also known as firewall analysis) is the process of analyzing and adjusting the configuration and policy set of a firewall to improve performance and security. This process involves reviewing and corelating log data and device configurations, identifying potential vulnerabilities and weaknesses, and providing recommendations for remediation. Performing these processes is complex, which is why tools like firewall analyzers are useful. They offer automation, visualization, and alerting to provide recommendations that can be used to reduce the risk of attack. What is the business impact of firewall optimization? Firewall optimization is important because it can help organizations improve their overall security, performance, and compliance, while also reducing costs and improving decision-making. This can ultimately contribute to better overall business performance. Firewall optimization can have a positive impact on a business's overall network security and performance. Some of the key benefits include: Improved security: Analyze configurations and log data to identify potential vulnerabilities and threats in the network and provide recommendations for remediation. This can help to reduce the risk of successful cyber-attacks and data breaches. Better performance: Improve overall network performance by identifying and addressing bottlenecks and inefficiencies in the firewall configuration. This can result in faster network speeds, more reliable connectivity, and better overall performance. Compliance: Comply with relevant regulations and standards, such as PCI DSS and HIPAA, by providing regular compliance reports and identifying potential compliance issues. Cost savings: By identifying and addressing inefficiencies and bottlenecks in the firewall configuration, firewall optimization can also help reduce costs associated with network maintenance and troubleshooting. Improved decision-making: Have a better understanding of the network security posture and the capabilities of the firewall. This allows organizations to make more informed decisions about their security strategy, and to better allocate resources for security initiatives. How is firewall optimization different from firewall management? Firewall optimization uses software tools like a firewall analyzer to find weaknesses and vulnerabilities in network attached devices. The inspection includes analyzing configurations and log data from security devices, such as firewalls, intrusion detection systems (IDS), and intrusion prevention systems (IPS). The primary features of a firewall optimization include: Log analysis: Review log data to understand utilization trends over time and recommend ways to enhance the performance of the firewall without compromising security. Configuration analysis and compliance reporting: Review running configurations of firewall devices regularly and include features for generating reports that show compliance with relevant regulations and standards, such as PCI DSS and HIPAA. Security analytics: Analytics capabilities allow users to visualize and analyze data from firewalls. This can help to identify trends and patterns that may indicate potential security threats. Alerting: Alerting features that notify users when potential threats or vulnerabilities are detected. Integration with other tools: Some firewall analyzers can be integrated with other security tools, such as vulnerability scanners or | Tool Vulnerability | ★★★ | |

WinorDLL64: A Backdoor From The Vast Lazarus Arsenal?
(published: February 23, 2023)
When the Wslink downloader (WinorLoaderDLL64.dll) was first discovered in 2021, it had no known payload and no known attribution. Now ESET researchers have discovered a Wslink payload dubbed WinorDLL64. This backdoor uses some of Wslink functions and the Wslink-established TCP connection encrypted with 256-bit AES-CBC cipher. WinorDLL64 has some code similarities with the GhostSecret malware used by North Korea-sponsored Lazarus Group.
Analyst Comment: Wslink and WinorDLL64 use a well-developed cryptographic protocol to protect the exchanged data. Innovating advanced persistent groups like Lazarus often come out with new versions of their custom malware. It makes it important for network defenders to leverage the knowledge of a wider security community by adding relevant premium feeds and leveraging the controls automation via Anomali Platform integrations.

[Eye Opener] Should You Click on Unsubscribe?
By Roger A. Grimes.
Some common questions we get are "Should I click on an unwanted email's 'Unsubscribe' link? Will that lead to more or less unwanted email?"
The short answer is that, in general, it is OK to click on a legitimate vendor's unsubscribe link. But if you think the email is sketchy or coming from a source you would not want to validate your email address as valid and active, or are unsure, do not take the chance, skip the unsubscribe action.
In many countries, legitimate vendors are bound by law to offer (free) unsubscribe functionality and abide by a user's preferences. For example, in the U.S., the 2003 CAN-SPAM Act states that businesses must offer clear instructions on how the recipient can remove themselves from the involved mailing list and that request must be honored within 10 days.
Note: Many countries have laws similar to the CAN-SPAM Act, although with privacy protection ranging the privacy spectrum from very little to a lot more protection. The unsubscribe feature does not have to be a URL link, but it does have to be an "internet-based way." The most popular alternative method besides a URL link is an email address to use.
In some cases, there are specific instructions you have to follow, such as put "Unsubscribe" in the subject of the email. Other times you are expected to craft your own message. Luckily, most of the time simply sending any email to the listed unsubscribe email address is enough to remove your email address from the mailing list.

2023-02-27 11:00:00 | Integrating Cybersecurity in UX design (lien direct) | The content of this post is solely the responsibility of the author. AT&T does not adopt or endorse any of the views, positions, or information provided by the author in this article. Image Source: Pexels Integrating Cybersecurity in UX design The digital landscape has ensured a wider range of businesses has access to a truly global marketplace. On one hand, this helps bolster a thriving entrepreneurial ecosystem. However, it also means there is a significant amount of competition. If your company’s website or mobile application doesn’t provide a stellar user experience (UX), consumers are able and willing to go elsewhere. Yet, in the online environment, UX is not your only consideration. There are various threats your business and consumers face from cyber criminals. Therefore, when developing your online tools, you need to adopt effective protections. Unfortunately, many businesses struggle with implementing strong security that doesn’t also disrupt the UX. Your best approach here is usually to integrate cybersecurity with UX design. So, let’s explore why and how you can achieve this. How are UX and Cybersecurity related? One of the mistakes too many businesses make is assuming that UX and cybersecurity are separate aspects of the digital infrastructure. They can certainly have independent intentions to an extent with different goals and actions to achieve these goals. Yet, understanding how they are closely related is the first step to effective integration. In some ways one can’t — or, at least, shouldn’t — exist without the other. A good example of this is the application of web design in high-stakes sectors, like telehealth care. There are two core types of telehealth services; asynchronous care and synchronous (live) care. While there is a difference here in how patients interact with the medical professional, both types involve the collection and storage of sensitive data. It’s certainly important from a UX perspective to make both asynchronous and live processes as simple and convenient as possible for patients. Yet, this simplicity shouldn’t sacrifice the security of the data. Clear and strong security protocols give consumers confidence in the system and the company they’re interacting with. This applies to not just healthcare industries but also eCommerce, education, and supply chain sectors, among others. Similarly, consumers may be more likely to adopt more secure behaviors if they can see how it feeds into the convenience and enjoyment of their experience. This means that the UX development process must involve security considerations from the ground up, rather than as an afterthought. How can you plan effectively? As with any project, planning is essential to the successful integration of cybersecurity and UX design. An improvisatory approach that involves tacking security or UX elements onto your site or app doesn’t result in a strong development. Wherever possible, your best route is to bring both the UX departments and cybersecurity professionals together in the planning process from the outset. Each department will have insights into one another’s challenges that benefit the project as a whole. Another key part of your planning process is researching and analyzing your users’ behavior concerning the types of online tools you’re developing. Work with business analytics professionals to understand in what ways security factors into your target demographic’s preferred online experiences. | Tool Medical | ★★ | |

2023-02-23 11:00:00 | Stories from the SOC - The case for human response actions (lien direct) | Stories from the SOC is a blog series that describes recent real-world security incident investigations conducted and reported by the AT&T SOC analyst team for AT&T Managed Extended Detection and Response customers.
Executive summary
As we move towards more automation, we should remember the risk of over-automating, or at least make a conscious decision to accept the risks. This is especially important in automating response actions, which left unchecked could wreak havoc with day-to-day business operations.
Investigation
The alarm
One evening after normal business hours, an alarm came in indicating a software package attempting to execute on a server was auto-mitigated by SentinelOne. The software package was behaving in a way that was taken as attempting to evade detection by the SentinelOne agent and therefore rated as “Malicious” by the SentinelOne Artificial Intelligence logic. Since the server on which the software package was attempting to execute had a “Protect” policy applied, the auto-mitigation steps for a dynamically detected “Malicious” rating included killing and quarantining the process.
A “policy” setting in SentinelOne is the defined level of automated response activity the endpoint detection and response tool (EDR) has permission to perform for each grouping of assets. Whereas a “Detect” policy will create an alert that can be managed for post-investigation response actions, a policy setting of “Protect” will take automated response actions. The intrusion level of those automated response actions can be customized, but they all perform an automated action without a person looking at the situation first.
The below image is for an alarm for malware which ended up being process automation software
but nonetheless was automitigated (process killed) by SentinelOne as shown in the log excerpt below.
The business impact
The next morning, with business hours back in full swing, the customer reached out to us concerned about the result of the automated response action. The customer stated that the software package is a critical part of their business infrastructure and should never be stopped from executing. The software had been running on that same server the prior several months, since entering SOC monitoring.
The customer questioned why after several months with the SentinelOne agent running on the server did the agent suddenly believe the software package was malicious. We were not able the answer the question specifically since the decision-making behind identifying and rating a process as “Malicious” versus “Suspicious” or benign is a proprietary logic.
What we could state is that any EDR solution worth its price will continually update indicator of compromise (IOC) signatures. Any worthwhile EDR solution will also include not only static detection but also behavior-based dynamic detection. In the case of SentinelOne, there is the pre-execution behavior analysis that allows for process termination pre-execution as well. And of course, any software package run on a server is subject to updates for security, efficiency, or product feature upgrades.
Taken as a whole, it means any endpoint being protected is a very dynamic battleground with the potential for an updated software package that did not trigger IOC rules yesterday triggering tehm today. Or a non-updated software package may suddenly be identified as potently malicious due to updated machine learning IOC behavior analysis. Remember when |

Coinbase Cyberattack Targeted Employees with Fake SMS Alert
(published: February 20, 2023)
On February 5th, 2023, several employees at the Coinbase cryptocurrency exchange platform received a fake SMS alert on their mobile phones. The message indicated that they need to urgently log in via the link provided to receive an important message. One employee got phished by the attackers, but they failed to login due to the MFA restrictions. The attackers, likely associated with the previously-documented 0ktapus phishing campaign, proceeded to call the employee and phish him for more information by pretending to be from the corporate IT. Coinbase was able to detect the unusual activity and stop the breach, although the attackers have obtained some contact information belonging to multiple Coinbase employees in addition to the login credentials of the phished user.
Analyst Comment: Network defenders are advised to monitor for access attempts from a third-party VPN provider, such as Mullvad VPN. Monitor for download of remote desktop viewers such as AnyDesk or ISL Online. Set up monitoring for Incoming phone calls / text messages from Bandwidth dot com, Google Voice, Skype, and Vonage/Nexmo. Anomali Premium Domain Monitoring service notifies customers regarding registration of potential phishing domains.

2023-02-21 11:00:00 | 7 reasons why Endpoint Security and Response shouldn\'t be ignored (lien direct) | The content of this post is solely the responsibility of the author. AT&T does not adopt or endorse any of the views, positions, or information provided by the author in this article. When strategizing a security approach for the coming year, many solutions will cross a CISO’s desk, all useful in covering some part of the network. Organizations must scrutinize every layer and each solution to make sure their security stack runs efficiently while still boasting a Defense-in-Depth approach. There cannot be an overload of alerts, the learning curve must be worth the cost, and all solutions must integrate with each other. Not surprisingly, the search can be tedious, complex, and confusing. Broadly speaking, cybersecurity defends the network and the devices on that network. Both are key and must be protected. Endpoint security and response includes “not only the automated monitoring and detection of threats on the endpoint, but also a combination of autonomous and manual investigation, remediation, and response.” While not every tool will make the cut, here are seven reasons why Endpoint Detection and Response (EDR) should not be ignored. Cybercriminals aren’t ignoring endpoints. It’s not surprising that in a recent study, 76% of IT decision-makers reported their company use of endpoint devices has gone up. This can include workstations, servers, tablets, smartphones and a host of IoT devices like cameras, smart speakers, and lighting. However, it is equally unsurprising that bad actors have capitalized on this gain, and consequently, 79% of IT teams have seen a rise in endpoint-related security breaches. The cyber talent crisis creates the need for autonomous response on the endpoint. With an increase of both endpoints and endpoint-related attacks, a proportional increase in endpoint security measures is needed; unfortunately, the ongoing cyber talent deficit hamstrings those efforts and makes whatever qualified cybersecurity experts are available difficult to attain for many small to medium-sized businesses. Endpoint security solutions use automatic investigation and monitoring techniques to spot threat 24/7/365 and often respond autonomously to mitigate them. This cuts back significantly on the work remaining for already-strapped security teams to do. EDR offers cloud-based security for end-user devices. One of the primary security problems facing fast-expanding, digitally native, and mid-transition companies is how to secure both on-premises and cloud-based assets. Endpoints, while not in the cloud, connect to it and bad actors can use vulnerabilities in device software to pivot to the rest of your network. State of the industry endpoint security platforms can deploy patches and run reboots from the cloud and offer enterprise-wide centralized cloud management. Remote device security trends downward as workers mix personal with professional. The rise of BYOD has been significant and ubiquitous in the wake of the remote-work migration, and a study by Gartner revealed that over 50% of workers used their own laptop or smartphone for work activity. Interestingly, a Ponemon study indicated that 67% of respondents reported that personal mobile devices have negatively impacted their company’s security posture, and 55% cite smartphones as | Tool Threat | Deloitte | ★★ |

#StopRansomware: Ransomware Attacks on Critical Infrastructure Fund DPRK Malicious Cyber Activities
(published: February 9, 2023)
The US and South Korea issued a joint advisory on ongoing, North Korea-sponsored ransomware activity against healthcare and other critical infrastructure. The proceedings are used to fund North Korea’s objectives including further cyber attacks against the US and South Korean defense and defense industrial base sectors. For initial access, the attackers use a trojanized messenger (X-Popup) or various exploits including those targeting Apache log4j2 and SonicWall appliances. Despite having two custom ransomware crypters, Maui and H0lyGh0st, the attackers can portray themselves as a different ransomware group (REvil) and/or use publicly-available crypters, such as BitLocker, Deadbolt, ech0raix, GonnaCry, Hidden Tear, Jigsaw, LockBit 2.0, My Little Ransomware, NxRansomware, Ryuk, and YourRansom.
Analyst Comment: Organizations in the healthcare sector should consider following the Cross-Sector Cybersecurity Performance Goals developed by the U.S. Cybersecurity and Infrastructure Security Agency and the U.S. National Institute of Standards and Technology. Follow the principle of least privilege by using standard user accounts on internal systems instead of administrative accounts. Turn off weak or unnecessary network device management interfaces.
