Risky Business: Securing a Remote Workforce Comes with Its Challenges – but Also Solutions
Arete Analysis

In the past year, businesses around the world have had to fundamentally transform how they work and communicate. And not that work from home is new, but it’s certainly never been done at the current scale. To maintain productivity, organizations have had to move quickly to connect a much broader remote workforce — but often without the necessary polices, technology, and training to ensure security.
Some of the more common issues with trying to secure a remote workforce are:
Remote desktop protocol: To connect remote workers to office systems, organizations can turn on remote desktop protocol (RDP), as it easily allows one computer to connect to another for remote use. The problem, however, is that cybercriminals continue to successfully target RDP exposed to the internet. In fact, remote access is the primary method of intrusion Arete sees in ransomware cases!
As a solution, organizations should consider implementing a virtual private network (VPN) with multifactor authentication (MFA), which allows distributed offices to connect securely.
Social engineering: Social engineering is all about deception. Threat actors try to trick victims into giving out confidential information that they can then use to gain access to other systems or data. For example, they may try to lure users into clicking on a link in an email; or they may call employees, claiming to be tech support and asking for passwords. The key is to remain vigilant. Don’t click on links or open attachments from suspicious sources. And always investigate any requests for money, personal information, or anything of value before handing something over.
Weak passwords: Weak passwords have resulted in many a breach. Organizations can address the issue by mandating complex and unique passphrases for all accounts, implementing password manager tools, and most importantly, implementing MFA wherever possible.
Outdated systems: Outdated software has vulnerabilities and might not be able to withstand an up-to-date attack by cybercriminals. Thus, it’s critical to continually update software and systems — all computers, phones, and tablets — with the latest patches and versions.
It’s the little things that are important. It’s the little things that put you at risk.
The Arete Managed Detection and Response (MDR) team recently helped a client address not only the security challenges above, but also a new one: remote workers’ home network security.
This work-from-home client had disconnected his home Wi-Fi router/firewall and plugged his laptop directly into the modem. A firewall establishes a barrier between a trusted network and an untrusted network, such as the internet. It prevents unauthorized access and inspects traffic to identify and block threats. By directly connecting to the modem and thus, the internet, the client exposed his laptop to scanning and attack.
Fortunately, Arete’s MDR analysts immediately saw threat alerts in their SentinelOne Endpoint Detection and Response (EDR) console. They quickly escalated the issue, locked down the laptop, and contacted the client. Next, they placed the laptop back behind the firewall, helping the client avoid a data breach or ransomware event.
Tips for maintaining home network security
If you are working remotely, there are several steps you can take to secure your home network:
Change the default username and password — on both the login to the router administrative controls and on the Wi-Fi network you join.
Turn on wireless network encryption. We recommend using the WPA3 protocol as it’s the most secure.
Most Wi-Fi routers have a built-in firewall. Check to see that the firewall is turned on.
Disable remote administration. Attackers are using this feature to break into home networks.
Keep the router software and firmware up to date. Manufacturers provide updates with important security fixes.
Have trained and experienced security staff investigate all alerts immediately. A fast response can mean the difference between
an hour of remediation and a full-blown ransomware event.Deploy an EDR solution like SentinelOne on all business endpoints — from servers to remote employee laptops.
Next-generation SentinelOne EDR for optimal protection
Ransomware operators often use polymorphic malware, which can easily evade even the most advanced enterprise antivirus solutions.
For this reason, Arete analysts use the next-generation SentinelOne EDR toolset. Designed to identify, kill, and quarantine any malicious executable found in an environment, SentinelOne relies on behavioral analytics — not common signature-based detection — and acts as a force magnifier for our experienced cybersecurity professionals. Its behavioral artificial intelligence (AI) automatically detects and remediates threats based on how they act and by leveraging dynamic threat intelligence gathered by Arete and SentinelOne analysts.

Europol Disrupts AudiA6 Crypto Laundering Service
European authorities have dismantled AudiA6, a major cryptocurrency laundering service linked to ransomware groups and broader cybercriminal networks. Between 2022 and 2025, the platform is believed to have processed over €336 million in illicit funds, enabling threat actors to obscure financial trails and monetize cybercrime proceeds. Its operators are also suspected of running Dark2Web, a dark web forum that facilitated collaboration, services, and connections among cybercriminals globally. This development underscores the expanding role of sophisticated, large-scale cryptocurrency laundering services in sustaining the cybercrime economy, enabling threat actors to obscure illicit funds and evade regulatory controls.
What’s Notable and Unique
Following law enforcement disruption of Cryptex and Garantex, AudiA6 emerged as another platform involved in financial activities linked to ransomware groups. Investigators believe that AudiA6 became a central hub for cybercriminals seeking to launder stolen digital assets while obscuring the transaction trail from authorities.
On June 10, 2026, a coordinated operation resulted in two arrests in Georgia, the dismantling of key infrastructure (30+ servers, 25 domains), the freezing or seizure of over €778,000 in crypto, and the takedown of the AudiA6 and Dark2Web platforms.
Analyst Comments
Ransomware groups and cybercriminal networks are increasingly leveraging sophisticated techniques, including chain-hopping, decentralized exchanges, and mixer-as-a-service platforms, to rapidly move illicit cryptocurrency across multiple blockchains, effectively obscuring transaction trails. Concurrently, the widespread use of fraudulent exchange accounts, mule wallets, and privacy-enhancing tools has elevated cryptocurrency laundering to a core enabler of the cybercrime ecosystem, allowing actors to bypass anti-money-laundering controls at scale. This investigation identified over 6,000 KYC records linked to money-mule accounts, many of which were tied to Russian-speaking intermediaries specifically recruited to facilitate the movement of illicit proceeds. These threat actors systematically used both commercial and domain-controlled email services to establish mule accounts across multiple cryptocurrency platforms. Collectively, these findings underscore the growing scale, coordination, and professionalization of cryptocurrency-enabled crime, highlighting the critical need for sustained, intelligence-led, and internationally coordinated efforts to disrupt these evolving financial ecosystems.

Threat Actors Leverage AI for EDR Evasion
A threat actor has developed and deployed a ransomware attack toolkit enhanced with AI-assisted development workflows, enabling automated Active Directory (AD) discovery and improved EDR evasion capabilities. The toolkit leverages agent-based AI systems, such as Claude’s Opus and Cursor agents, for iterative malware development, testing, and refinement.
What’s Notable and Unique
Researchers have highlighted that this toolkit can not only generate ransomware code but also bypass sophisticated security defenses and identify AD networks for malware distribution.
The framework incorporates multiple capabilities, including automated AD discovery and reconnaissance mechanisms, iterative EDR testing environments to refine evasion techniques, and a command-and-control (C2) infrastructure that leverages Telegram APIs and Cloudflare redirectors for stealth.
Additionally, some agents were tasked with checking security research and technical posts for various bypass techniques. The agents recognized what was required for reproduction, extracted the techniques, mapped them to the MITRE ATT&CK knowledge base of adversary behaviors, set up a test lab, carried out the methodology, and reported the results.
After a few repetitions, the modules seemed to avoid nearly all EDR solutions, despite the agent’s initial suggestion of a high failure rate. Although researchers found no evidence that AI was embedded in deployed malware or was operating independently in victim environments, the technology was still used to accelerate the iterative process of developing, testing, and refining payloads against security products, shortening the period between the publication of offensive security research and its practical implementation by threat actors.
Analyst Comments
AI-driven tools like this could accelerate the pace and sophistication of ransomware attacks, enabling even relatively inexperienced actors to launch high-impact campaigns. This development underscores the urgent need for security solutions to adapt to AI-assisted threats. Organizations must respond by strengthening detection engineering, improving visibility across environments, and maintaining robust security fundamentals.

CMS Vulnerability Leads to ClickFix Campaign
Threat actors compromised at least 700 education and technology websites in a recent ClickFix campaign by exploiting a critical SQL injection flaw (CVE-2026-26980) in the Ghost content management system (CMS). Adversaries combined the vulnerability with the ClickFix social engineering tactic to steal admin keys and inject a malicious JavaScript that delivers a fake Cloudflare or CAPTCHA verification pop-up, tricking victims into copying and pasting a malicious command into their systems.
What’s Notable and Unique
Rather than targeting the end user first, this campaign is unique in its initial exploitation of the system, followed by social engineering attempts. This hybrid attack style is likely being leveraged to bypass traditional defenses.
This recent campaign also highlights how trusted web properties can be weaponized at scale and coupled with unpatched CMS vulnerabilities. Rather than using the CMS compromise to perpetrate a single attack, threat actors turned it into a supply-chain attack that ultimately affected over 700 trusted websites.
Analyst Comments
As network defenders and their tools enhance threat detection capabilities, adversaries increasingly seek methods to bypass these defenses. By combining vulnerability exploitation, social engineering techniques, and staging for ancillary attacks, this campaign successfully bypassed traditional defenses and inflicted significant impact. Defending against hybrid cyberattacks requires comprehensive security controls beyond simply patching vulnerabilities. Organizations should focus on limiting movement within the environment, detecting abuse of trusted applications, and preventing end-user manipulation.
