Protecting Our Clients with Richter Guardian
A client fell victim to an Apple Support impersonation scam after a pop-up and remote access. See how Richter Guardian onboarded her, secured her devices, and restored her peace of mind.
CrowdStrike Update Cripples Windows Systems
INTRODUCTION
On July 19, CrowdStrike released a flawed update to its Falcon sensor for Windows devices, triggering widespread system crashes. Due to a bug in the content validator and insufficient testing, the update bypassed CrowdStrike’s internal quality checks.
The update reached over 8.5 million Windows devices, resulting in an out-of-bounds memory read that caused the Falcon sensor to crash the operating system, leading to the infamous Blue Screen of Death (BSOD). The impact was severe, with enterprises across various sectors, including airports, hospitals, government agencies, media outlets, and financial institutions, experiencing critical and costly IT disruptions.
Both Windows workstations and servers were affected, leading to massive outages that incapacitated entire organizations and rendered hundreds of thousands of computers inoperable.
ROOT CAUSE
The issue stemmed from a recent update to the CrowdStrike Falcon sensor, which caused Windows systems to either get stuck in a boot loop or crash with the Blue Screen of Death. CrowdStrike acknowledged the problem and issued a technical alert, stating that its engineers had “identified a content deployment related to this issue and reverted those changes.
Despite the swift response, it took days for some organizations to restore normal operations, resulting in prolonged outages and delays. While most organizations have since recovered, the repercussions of the incident continue to unfold, with increased cybercriminal activity, loss of trust, and potential litigation.
According to a report by Guy Carpenter, the estimated insured losses from the faulty Falcon update range between $300 million and $1 billion, while CyberCube has suggested the figure could be as high as $1.5 billion.
THE IMPACT ON PERSONAL COMPUTERS
CrowdStrike warned users that cybercriminals were exploiting the Falcon outage. Phishing attempts, posing as CrowdStrike representatives, surged as attackers sought to distribute malware. A significant example involved a fake recovery manual that installed a new information-stealing malware called Daolpu. Once active, this malware harvested account credentials, browser history, and authentication cookies stored in browsers like Chrome, Edge, and Firefox.

The Challenge
In our modern digital landscape, cybersecurity threats are an equal-opportunity challenge that can impact anyone, anywhere. As our world becomes more interconnected through technology, it’s crucial to recognize that cybersecurity isn’t just a concern for tech experts; it’s a shared responsibility that affects us all.
In one such case, a client found herself facing a daunting cybersecurity challenge. While browsing the internet, she received a pop-up message claiming that her computer was compromised by a virus. The message instructed her to call a specific number, which were impersonating Apple Support. Unfortunately, she fell victim to this scam, leading to a compromise of her computer.
The root cause analysis suggests that her computer might have been compromised during the installation of browser filters to block ads, where cybercriminals took possession of her computer system for 45 minutes. The client was distressed upon receiving a fraudulent invoice, wondering how this happened to her. This case study highlights the importance of cybersecurity and how Richter Guardian can offer a solution.

23andMe User Data Stolen in Credential Stuffing Attack
23andMe confirmed customer data was exposed via credential stuffing and the DNA Relatives feature. We explain how it happened and how to secure your account and check for breached credentials.
Introduction
The public biotechnology and genomics firm, 23andMe, confirmed on their website on October 6, 2023, that certain 23andMe customer profile information was circulating on hacker forms. The information that has been exposed from this incident includes full names, usernames, profile photos, sex, date of birth, genetic ancestry results, and geographical location. As a result, 23andMe have notified their customers, and have pushed for them to reset their passwords and enable multi-factor authentication (MFA).
How the Attack Happened
The hackers used credential stuffing to gain access to a set of user accounts on 23andMe. Credential stuffing is a type of cyber attack in which a hacker uses stolen usernames and passwords (obtained from another breach or purchased off the dark web) to access other websites in which the users are registered. Users that recycled their breached login credentials on 23andMe may have been the entry point for this attack.
A subset of the compromised users opted into 23andMe’s DNA Relatives feature, which allowed for hackers to scrape the data of their DNA Relative matches.
The number of accounts affected has not been released or disclosed by 23andMe.
If you think you may have been affected by this recent breach, reset your password, and opt for MFA on 23andMe. While the account may or may not be compromised, it is important that cybercriminals do not leverage your breached credentials to access other websites in which you may have an account on.
How to Stay Safe
- Reset All Passwords – If you have the bad habit of reusing passwords across different websites, reset those passwords and employ hard-to-guess, complex passwords on those websites.
- Password Manager – To keep track of your complicated passwords, think about investing in a password manager. Password managers, like 1Password, place a secret key on your password manager to add a unique extra layer of security.

Check-In Safely – Phishing Campaigns Target Hotels and Travel Agencies
Cybercriminals are targeting hotels and travel agencies with social engineering, then using compromised systems to phish customers. Learn the attack chain and how to stay safe when you travel.
Introduction
The tourism industry is crawling back to pre-pandemic numbers thanks to travel and lockdown restrictions being lifted globally. Unfortunately, cybercriminals have also come up with a new and sophisticated campaign to breach the systems of booking sites, hotels, and travel agencies. Subsequently, the cybercriminals use the systems of the compromised hotel or travel agency to send phishing emails to existing customers.
Summary of Hotel and Travel Agency Phishing Scam
- The Entry Point – The campaign starts with the threat actor inquiring about a reservation with the hotel or travel agency. Upon booking the stay, the threat actor uses ‘advanced social-engineering techniques’ to inquire about specific or special accommodations.
- Tricking Employees – After establishing a sense of urgency with the hotel employee, the threat actor sends over a URL via email, which supposedly contains crucial documents relevant to their accommodations. The URL provided directs the hotel employee to a genuine hosting site (Google Drive, Dropbox, etc.) and the hotel employee downloads an archive file thinking that it contains important documents.
- Malicious Executables – The archive file that was downloaded by the hotel employee contained malicious executables (malware) that would infiltrate the hotel employee’s computer. From there, the malware operates stealthily to capture login credentials, financial information, and other sensitive data without the hotel employees being aware.
- New Target – Once threat actors have successfully compromised the hotel’s system, the threat actors can move onto using the hotel’s communication channel to target legitimate customers.
- Phishing – The threat actors can now send phishing messages disguised as legitimate requests from the compromised hotel or travel agency. The phishing messages will ask for additional credit card verification from the customer. Since the message comes directly from the booking site through a legitimate communication channel, the customer has no reason to doubt the legitimacy of the email.
How to Stay Safe
- Avoid Clicking on Unsolicited Links – Always be skeptical of unsolicited links, even when they originate from a trusted source. Check URLs for any indicators of deception.
- Take Your Time – Threat actors, phishing emails, and sketchy requests for payments will typically call for immediate action. Take your time to discern any emails that require you to transfer sensitive information.
- Trust Your Instincts – If you are suspicious about a suspicious email, call the hotel or travel agency directly to confirm that the communication is indeed legitimate.
