The patient tally from the Synnovis ransomware attack continues to grow two years later, with Mid and South Essex NHS Foundation Trust confirming it was caught up in the breach. The trust told The Register that the Synnovis breach affected about 2,380 records relating to patients who underwent specialist diagnostic testing. The disclosure follows a similar announcement by Bedfordshire Hospitals NHS Foundation Trust, which earlier this month said that almost 33,000 patient records had been caught up in the same breach. According to Mid and South Essex, some of the compromised data cannot yet be directly linked to individual patients, meaning the trust is still unable to determine the final number of people affected. It also said the precise time period covered by the stolen records has yet to be established, although patients tested after June 3, 2024, the day of the attack, were not affected. "We are still waiting for confirmation on exact numbers," Dawn Scrafield, deputy chief executive of Mid and South Essex, told The Register. "Once we have established who those patients are, we will be in contact with any who have been affected." The disclosure highlights the drawn-out fallout from the attack. Synnovis told us it completed its forensic review by the end of last summer and said it had notified all affected organizations by November. However, Mid and South Essex said it was only informed in December 2025 and is still trying to work out exactly which patients are tied to the compromised records six months later. "Any decision on patient notification, including the number of patients to be notified, is made by the affected organization as part of their assessment," a Synnovis spokesperson said in a statement. "Synnovis, as the Processor of the data, is not involved in any of the assessments regarding if, when or how many patients a Controller determines necessary to notify." The company said it does not believe the stolen information presents a high risk to individuals because of its fragmented nature, but acknowledged that affected organizations are still assessing what was taken and whether patients should be contacted. The breach was one of the most disruptive cyber incidents ever to hit the NHS. The Qilin attack crippled pathology services across south east London, forcing hospitals to cancel thousands of appointments and operations while clinicians struggled with delays to blood testing and transfusion services. Patient data was later published online after the gang's extortion attempt failed. However, the fallout wasn't limited to canceled operations and delayed blood tests. Last year, King's College Hospital NHS Foundation Trust confirmed that delays caused by the outage contributed to the death of a patient, marking one of the first officially acknowledged fatalities linked to a ransomware attack. ®

There's another likely North Korean-linked scam hitting developers and their employers, while snarfing up credentials and cryptocurrency - and this one doesn't even involve embedding IT workers at high-profile tech giants. A previously unseen phishing crew, suspected to have DPRK ties, sent more than 250 emails to people working in almost 100 organizations, mostly based in the US, over six weeks in April and May. According to security sleuths, it is yet another digital-heist attempt designed to steal cryptocurrency wallets and developers’ credentials. Proofpoint threat researchers spotted this campaign and tracked the digital thievery as UNK_DeadDrop. Like earlier phishing expeditions from the Norks, including the Contagious Interview campaign, this one uses developer recruitment or code review lures to target victims, primarily in technology, education, business services, and financial services, and ultimately steal credentials and cryptocurrency. In another common tactic seen with DPRK-linked credential-stealing activities, the lures attempt to send victims to attacker-controlled GitHub repositories hosting malicious scripts that execute cross-platform malware across macOS, Linux, and Windows machines. “However, there are several differences between the activity sets, such as the shift in social engineering from arranging fake interviews to unsolicited job offer or code review approaches as well as the move from delivery platforms such as LinkedIn to email,” researchers Saher Naumaan and Carlos Rubio said in a Monday blog, citing other differences between UNK_DeadDrop and Contagious Interview. “Based on the use of email for initial access, the high volume of emails, industrialization and scale of repository creation, a new self-contained payload, and distinct infrastructure from previous Proofpoint observations of Contagious Interview campaigns, Proofpoint Threat Research continues to track UNK_DeadDrop activity as an independent cluster,” the researchers wrote. Full-stack engineer wanted The attacks begin with an email that looks like it originated from a real company, with job offers for developer roles including “Full-Stack Engineer” or “Agent Lead Developer” positions. Proofpoint caught the crooks spoofing a handful of companies to send these emails from attacker-owned sender domains including: Ondo Finance: a decentralized finance (DeFi) platform Empower Pharmacy: a pharmaceutical company NXLog: a log collection and centralization tool OnePlan: a strategic portfolio and work management platform Hypen Connect: a Web3 and AI Talent Agency Valon: a mortgage service provider Nourish: a telehealth company The emails contain links to GitHub repos disguised as coding assignments or cryptocurrency-related projects - part of the phony job application process. All of the emails instructed the target to clone the repository and open it in a code editor like VS Code or Cursor. Proofpoint’s report lists all 10 repositories, all focused on four themes - cryptocurrency platforms, exploit archives, Foundry testing, and AI payments - and all hosted by different GitHub accounts, so be sure to check out the vendor’s list. In May, the attackers switched tactics and began sending victims requests for peer reviews on open-source projects, with a potential job offer based on the fixes. These emails purported to come from cryptocurrency trading or prediction companies, including Pulsynk and Trixauvex. Another UNK_DeadDrop campaign in late May targeted finance and technology companies, requesting recipients to test an ERC-4626 vault in Foundry, a toolkit for Ethereum and smart contract development. In all of these instances, when the victim opens what they believe to be a legit repository folder in an integrated development environment, a pre-configured task silently executes and triggers a platform-specific loader that decodes embedded payloads on whatever system the developer uses, working across Linux, macOS, and Windows machines. The loader installs a malicious VS Code extension (VSIX) masquerading as a legitimate Google service. Every time the user opens the code editor on macOS or Linux, the VSIX extension activates, and relaunches the infection-chain if it’s not already running. The persistence mechanism doesn’t work on Windows machines, however. After installing VSIX, the infection chain looks different, depending on what platform the target uses. The Linux and macOS attacks use a native Go binary that connects to the command-and-control (C2) infrastructure as a persistent remote access trojan (RAT). The Windows chain, however, runs a Node.js pipeline inside the editor's Electron process. Both use the same C2 infrastructure and exfiltration endpoints. Linux, macOS backdoors The Linux and macOS binaries are based on the open-source Overlord C2 framework - this is a legitimate red-team tool that automates covert infrastructure setup and management, and orchestrates post-exploitation activities. This, of course, also makes it a very handy tool for attackers. For this campaign, the North Koreans added three custom modules: browserlogin (Chrome and Firefox credential theft), companywallet (crypto-wallet stealer and exfiltration), and cleanup (anti-forensic removal of workspace artifacts). On macOS, Overlord first collects wallet extension data, browser profile artifacts, and standalone wallet directories, compressing them into a ZIP and uploading them to the C2 server. Five minutes later, the malware moves on to credential theft, using a second embedded Mach-O binary that displays a fake system dialogue and prompts the user to enter their password. The Overlord process validates the credentials, and assuming they are legit, the malware modifies keychain access-control lists across Chrome, Brave, Edge, Opera, Vivaldi, Arc, Yandex, and other Chromium-based web browsers, before extracting Safe Storage keys and sending all of the stolen goods - collected credentials, Safe Storage keys, and keychain data - to the attacker-controlled server. The backdoor also re-launches itself as root, using the stolen password. The Linux malware follows a similar pattern, first scooping up wallet-related data and sending that via ZIP to the C2 server before moving on to credential theft. It, however, uses Zenity, a standard GTK dialog tool, to create a prompt and collect victim credentials. This backdoor attempts to steal passwords from GNOME Keyring by spawning Python 3 processes for each browser, and ultimately re-launches itself as root using a swiped password. Windows attacks Windows attacks run entirely as JavaScript inside the editor's Electron process, which appears as Code.exe in Task Manager. The malware first steals wallet info, targeting 35 wallet extension IDs (MetaMask, Phantom, Rabby, Keplr, and others), 18 standalone wallet applications (Exodus, Electrum, Ledger Live, Monero, Solana CLI, Bitcoin, and others), and Firefox profiles. Next, it installs Python and executes a stealer (detect_malware.py) for each browser profile that collects a ton of credentials across Chromium and Firefox browsers, steals cookies from Chrome/Edge/Brave and uses COM Elevation Moniker to access credentials across these browsers protected by App-Bound Encryption. It also attempts to read locked databases using five cascade methods, and ultimately uploads all the secrets to the same endpoint before terminating. “UNK_DeadDrop activity suggests North Korea-aligned operations targeting developers for financial gain are maturing and evolving,” Naumaan and Rubio wrote. “The shift from active social engineering over social media platforms to conduct fake interviews to large campaigns of recruitment-themed phishing emails distributing links to malicious repositories could indicate an actor industrializing and scaling operations.” ®

Check Point released an emergency fix on Monday for a critical authentication bypass vulnerability affecting its Remote Access VPN and Mobile Access deployments - but attackers, including ransomware criminals, got a month-long head start. Attacks against the bug, tracked as CVE-2026-50751, began on May 7, according to Check Point VP of research Lotem Finkelstein, and picked up in early June. The security software vendor spotted suspicious activity and began investigating the zero-day on June 4, Finkelstein said in a Monday blog. “We have observed indications that exploitation has been limited to a relatively small number of targeted organizations (several dozen globally), primarily over the past few days,” Finkelstein wrote, adding that, in at least one case, investigators observed post-compromise activity associated with a Qilin ransomware affiliate. This same ransomware scum is also likely exploiting other VPN-related vulnerabilities in Palo Alto Networks, Fortinet, and F5 products, Finkelstein said. CVE-2026-50751 is due to a logic-flow weakness in the Remote Access and Mobile Access certificate validation process, and it allows remote attackers to bypass authentication and establish a remote access VPN connection without a user password. It affects Mobile Access/SSL VPNs, Remote Access VPNs, and Spark Firewalls configured to use the deprecated IKEv1 key exchange protocol. While investigating CVE-2026-50751 and affected VPN components, Check Point found another vulnerability, CVE-2026-50752, in its Security Gateways and Spark Firewall products. It’s due to a bug in the certificate validation logic of the deprecated IKEv1 key exchange method, and can lead to man-in-the-middle attacks on the VPN site-to-site configuration. Check Point says that it hasn’t received any reports of in-the-wild exploitation of CVE-2026-50752. Check Point urges customers running vulnerable gateways and firewalls to apply the hotfixes, and the vendor also provided alternative mitigation options with instructions in the security advisories. The software provider also published a list of indicators of compromise, including attacker IPs, and recommends customers search Check Point SmartConsole logs for possible VPN certificate authentication attempts associated with observed attacker infrastructure and certificate subject names for at least May 7 through June 5. ®

An Illinois high school won't reopen until Wednesday at the earliest after suffering a ransomware attack on Sunday, June 7. Evanston Township High School (ETHS), located 14 miles north of Chicago, said it would be closed today and tomorrow, and that the closure also affected summer school, sports camps, and on-campus activities, which are all canceled. "Upon discovering the incident, we immediately activated our incident response procedures and engaged external cyber breach attorneys and cybersecurity forensic experts to assist with the investigation and recovery process," ETHS said in a statement issued via a dedicated information page. "We are working with these specialists to determine precisely what information may have been accessed or acquired and to restore normal systems operations as quickly as possible. The district is cooperating with the Federal Bureau of Investigation (FBI) as part of the ongoing investigation." It said that phone systems are down and staff have limited access to emails. Children and their families may also not be able to access certain online resources, all of which suggests the institution may still be in the containment phase of remediation. Among the online resources currently offline is Home Access Center, which is powered by PowerSchool. PowerSchool itself was was at the center of a cybersecurity disaster in late 2024. However, ETHS has not linked the platform to the ransomware attack. All staff other than safety and operations workers were told to work from home, although their work will be limited since, for the time being, they're locked out of the district's Google accounts and "other network systems, including eSchool." "We understand this situation is disruptive and appreciate your patience and flexibility," ETHS went on to say. "Additional updates and instructions will be provided as they become available." No major ransomware group has claimed responsibility for the intrusion at the high school yet. Education under attack The ETHS incident follows a separate attack on the education sector disclosed on June 4 that affected 13 schools in Powys, Wales. Powys Council set up its own information page about the attack, although it has not revealed much, saying it is awaiting the outcome of investigations by external specialists. However, it said the attack has affected "some school systems" and personal data belonging to both staff and pupils was accessed. The council identified 13 affected schools, although the compromised data only appears to have been taken from one of these, according to current information. Its information page repeatedly uses the phrase "because of the sensitive nature of the data." The council cites this as the reason for not revealing information such as which schools were affected, how many individuals are affected, what types of data have been accessed, and whether this included sensitive or safeguarding-related data. It also refused to say whether the attack involved ransomware or who was responsible for it. However, it said the risk of identity fraud would vary by individual, hinting that different types of personal data may have been accessed. Powys Council confirmed that all schools across the region remain open, and the cyberattack does not affect their day-to-day safety or operations. Education remains a strong target for cybercriminals. Given the sensitivity of the data these organizations store, it makes the sector one of the most attractive for financially motivated criminals looking for an extortion payment. In the UK, the Information Commissioner's Office said that between 2022 and 2024, pupils were responsible for 57 percent of 214 school data breaches, often using stolen login details. ®

Microsoft’s GitHub has disabled over 70 repositories after they were reportedly compromised by a worm in the latest open source supply chain attack. The code shack took down 73 repos within the space of 105 seconds after its alarms were tripped on Friday, June 5, after detecting signs of the Miasma worm infecting its projects, according to StepSecurity’s co-founder and CTO, Ashish Kurmi. Users reported issues quickly on Friday, after visits to those repos all resulted in the same message displayed, indicating that they had been disabled due to terms of service violations. According to StepSecurity’s analysis, the attack kicked off after a compromised contributor account pushed a malicious commit to Azure/durabletask. The commit dropped configuration files that triggered remote code execution on machines when a developer opened the repo in an IDE or AI coding tool, such as Claude Code, Gemini CLI, and Cursor. Several developers soon reported broken CI/CD pipelines, a support thread showed, although a moderator said at the time this was due to “an internal management issue.” "The repo that most immediately caused issues was Azure/functions-action,” Kurmi wrote, used to deploy code to Azure. With it being taken down, every workflow that referenced Azure/functions-action@v1 stopped resolving. GitHub stepped in a few hours after the repos were infected by the malicious commit. Its automated detections kicked in and disabled the repos in under two minutes, in two separate waves. However, it was the borking of the durabletask family that hinted at the bigger picture, that the attack was indeed a re-opening of the previous Miasma worm attack that hit Microsoft last month. Microsoft’s durabletask PyPi package was a previous target of the Miasma worm on May 19. Within a 35-minute window, three versions of the package were uploaded to PyPi, which planted infostealers on developers’ machines, specifically sniffing out cloud secrets and developer tool configurations on Linux systems. Crucially, the re-targeting of durabletask suggests the tokens associated with the compromised developer account used to execute the PyPi attack were not fully rotated, allowing an attacker to gain access and push commits to GitHub, Kurmi said. It was either that, or the contributor was re-compromised through the worm's own propagation loop, or a different contributor's token was used but the attacker altered the metadata to make it look like a repeated attack. Security shop Snyk described Miasma as a descendant of the Mini Shai Hulud worm. It’s the same one that ravaged open source packages over at the npm registry, including Red Hat’s, earlier this month. Cybercrime group TeamPCP claimed responsibility for developing Mini Shai Hulud, which itself is named after an earlier worm of the same name, sans “mini.” However, because TeamPCP open-sourced Mini Shai Hulud, it’s difficult to tell whether it was also behind Miasma or if someone else took the reins on the follow-up project. StepSecurity also reported that two days before the Microsoft attack, the same worm was making a nuisance of itself at npm, compromising more than 50 packages, including a Vapi.ai SDK with more than 408,000 monthly downloads. The Register asked Microsoft for comment, but it did not immediately respond. ®

Meta has asked a federal judge to hold Israeli spyware maker NSO Group in contempt of court after claiming it caught the surveillance vendor targeting WhatsApp users again despite a permanent injunction ordering it to stop. In a blog post on Monday, Meta said it had disrupted "NSO-linked social engineering attempts" after investigating reports from users. According to the company, the activity involved attempts to lure targets into clicking malicious links that redirected them to websites outside WhatsApp, as well as the creation of test accounts and groups on the messaging platform. "We successfully disrupted NSO-linked social engineering attempts after investigating user reports," Meta said. "They tried to trick people into clicking on malicious links to drive them to external websites outside of WhatsApp, similar to previously reported 1-click phishing campaigns linked to NSO." WhatsApp also published a handful of domains it linked to the campaign, including ikhwancast[.]com, ghazacast[.]com, and fr24cast[.]com, and said it was releasing indicators to help organizations identify related activity. The move marks the latest chapter in the long-running legal battle between Meta and the Israeli spyware maker. A US court found NSO liable in December 2024 for hacking WhatsApp users via its Pegasus spyware. In May 2025, a jury awarded Meta roughly $168 million in damages, but the judge later cut that to $4 million while issuing a permanent injunction barring NSO from targeting WhatsApp or its users. Meta, however, says NSO didn't get the memo. "Last year, WhatsApp made history by securing a landmark verdict and permanent injunction barring NSO Group ... from targeting WhatsApp and its users ever again," the company wrote. "Today, we're asking the court to hold them in contempt of that order." The company provided few technical details about the activity, such as when it occurred, how many users were targeted, whether any compromises were successful, or how it attributed the operation to NSO. Meta did not respond to The Register’s questions. However, the blog post adopts a hard line on the spyware industry than previous updates, repeatedly describing commercial spyware as a national security issue. "When a malicious company on the US government's Entity List continues to defy US courts, existing restrictions must remain firmly in place," WhatsApp wrote. "Easing them would undermine US national security and put American companies and billions of people worldwide who depend on secure communications at risk." If Meta's allegations are accurate, the episode suggests that a court loss is not enough to persuade a spyware vendor to leave a high-value target alone. ®

Oxford University students seeking work will be dismayed to learn that crooks have breached a second external platform provider for the university in as many months. The institution’s CareerConnect platform, provided by Group GTI, was the target of the intrusion, which exposed users’ full names and email addresses. Those who don’t use single sign-on (SSO) had their encrypted passwords leaked, too. CareerConnect forms part of Oxford University’s career services department, supporting students and alumni to find work opportunities. It is available to students, alumni, research staff, and recruiters. The same underlying technology powering the platform, which GTI markets as TargetConnect, is used by other universities in the UK and overseas, according to its website. OxfordUni said the May 28 attack was enabled by a “security vulnerability,” which has since been fixed. GTI has not publicly disclosed the security snafu itself, and did not respond to our requests for more information. The London-based tech company has not confirmed how many individuals were affected by the break-in, nor whether any data was stolen. It has also not explicitly stated which types of individuals were affected, although Oxford’s announcement listed “alumni, research staff, and employer users” as those who had their passwords forcibly reset following the attack. “There is no evidence that course information, uploaded files, appointment information, or financial information were involved in this incident,” the announcement went on to say. “GTI has stated this breach appeared to be focused on gathering credentials which may lead to phishing attempts.” The university did not list current students as among those affected, but told student newspaper Cherwell that names and email addresses might be compromised, and said the attack was entirely separate from the one which hit Instructure’s Canvas last month. Twice bitten Oxford University was just one of the circa 8,800 educational institutions affected by the mega breach at Canvas, a separate platform that’s also relied upon by schools, colleges, and universities. Seemingly timed by ShinyHunters to coincide with exam season, students across multiple countries were left without access to learning materials, tests, and grades at a pivotal time of the year. The scale of the attack was vast, affecting the usernames, email addresses, course names, enrollment information, and messages of up to 275 million students, teachers, and staff. The severity of the situation, coupled with the inopportune timing, led to Instructure “reaching an agreement” with ShinyHunters to prevent the criminal gang from leaking all the data online. In cyberese, this implies Instructure paid the criminals an extortion fee in exchange for their word that they would delete the stolen data. "We received digital confirmation of data destruction (shred logs)," Instructure said, adding "We have been informed that no Instructure customers will be extorted as a result of this incident, publicly or otherwise." ®

If they don't get you online, they'll try in person. A data-theft and extortion gang has targeted “dozens” of banks, law firms, and other professional services companies in the US from January through May, using fake help desk calls and other social-engineering techniques to gain access to corporate IT environments, according to Google’s Mandiant incident response team. And when those remote-deception methods don’t work, the criminals sometimes show up at victims’ physical offices, posing as IT technicians, and attempt to steal sensitive files using thumb drives. Google’s threat hunters track the extortion threat group as UNC3753, while other analysts call it Luna Moth, Chatty Spider, and Silent Ransom Group. The crew has been around since 2022, originally using fake software renewal emails and other billing lures, typically with PDF attachments containing phone numbers for attacker-controlled call centers, as their means of gaining initial access to corporate networks. Beginning around March 2025, the crims shifted tactics and started posing as IT help desk staff. “While UNC3753 primarily relies on digital vectors, GTIG assesses that associated threat actors have also attempted direct data theft using physical, in person access,” Google incident responders and researchers Chad Reams, Tufail Ahmed, Keith Knapp, Ashley Frazer, and Tyler McLellan said in a Friday blog. The authors also pointed to a May FBI alert to corroborate this in-person tactic. According to the feds, Silent Ransom Group crooks have been walking into law firms’ physical offices as recently as this spring. Once they are on-site, they claim to be IT support staff needing to image a device or create local backups for security reasons. If that line works, they plug a thumb drive into the victim’s computer and steal data the old-fashioned way. “Although limited forensic evidence and the absence of a subsequent extortion attempt prevent formal attribution, GTIG assesses that these physical intrusions are likely associated with UNC3753 based on structural, timeline, and targeting overlaps,” the blog said. Google won’t say how many dozens of firms have been targeted in these attacks, or how many ended in the data thieves paying a visit to the victims’ locations. “While we can’t share additional details regarding specific investigations, Mandiant CTO Charles Carmakal notes that this tactic has been observed over the years,” a spokesperson told The Register. “Mandiant has investigated various matters where adversaries planted insiders, bribed employees, or physically entered buildings to facilitate cyberattacks.” Another noteworthy thing about UNC3753’s attacks: they are very fast. In many of Mandiant’s investigated incidents, the entire operation from initial contact to data extortion occurred in just one day. “Recently, Mandiant observed data searches, staging, and theft initiated in under an hour,” the threat analysts warned. These intrusions typically begin with an invoice-themed email - but these don’t usually contain any malicious links or attachments. The email’s sole purpose is to give the miscreants a plausible reason to follow up via phone, so that the recipient is more likely to believe the call is legitimate. Most of the crew’s entry mechanisms involve voice-phishing, using a method that has worked so well for other groups like ShinyHunters and Scattered Spider over the past few years. UNC3753 calls organizations’ employees directly and purports to be a help desk worker or member of the security team. The criminals say they need the target’s help addressing a security issue or aiding with a corporate data migration project, and convince the individual to join a screen-sharing session via Zoom, Microsoft Terminal Services, Microsoft Teams, or Quick Assist. In one such intrusion, using Teams to gain access to the victim’s computer, the attacker jumped on five separate calls with the same target over a three-day period, we’re told. And in more than one incident that Mandiant responded to, UNC3753 established Zoom sessions directly on targets' personal laptops, using these machines to access corporate virtual desktop infrastructure (VDI) using native client platforms, such as Windows 365 or Citrix clients. Once they’re in the corporate systems, the intruders map local directories and network drives, and target specific legal and document storage repositories. The crooks also use very-specific keyword searches to find sensitive folders containing tax logs (Forms W-2, W-9, and 1099), audit files, corporate client agreements, and Social Security numbers, before staging this data for exfiltration. UNC3753 uses several methods to sneak the data out of the corporate IT environment without setting off any security alarm bells, including using portable versions of free Windows file manager WinSCP or another open source filesystem like Rclone. The crew has also been known to log into a file-sharing account from the victim’s browser and upload the stolen files that way - or even instruct the victims to send the files to an attacker-controlled email address. After stealing the data, they send the extortion email, usually within 30 minutes of exiting the victim’s environment, and set a three-day deadline to respond and begin the negotiation process. “We hope to find a financial solution that will be acceptable for both parties,” reads one such extortion email. It continues: In case of ignorance or no agreement, We will notify your employees, partners and customers, after which We will publish your data. You will receive claims from individuals, and legal entities for information leakage and breach of contracts, your current deals will be terminated. Journalists and others will dig into your documents, finding inconsistencies or violations in them. Your organization will lose its reputation, shares will fall in price, and your organization will be forced to close. Stay safe, friends In the Friday report, Google’s threat hunters list IP addresses and other indicators of compromise, including these phishing domains that UNC3753 uses in its social-engineering attacks, all designed to look like the target organization’s help desk: -itdesk[.]com, -it[.]com, and -helpdesk[.]com. The security shop also suggests a range of things companies can do to avoid falling victim to this group and other voice-phishing scams or physical office intrusions. Some of the physical controls include requiring visitors to display official credentials and photo identification, and mandating front-desk staff log all visitor IDs before granting access. Also, check pre-scheduled work orders to ensure the “technician” at the front desk is who they say they are, and make sure any visiting technical service workers are always accompanied by a corporate, in-office supervisor. Because the bulk of these intrusions occur without any physical entry into the office, however, companies should also implement remote access conditional access policies to ensure only corporate-owned devices can authenticate to any VDIs or VPNs. Plus, block the installation and execution of unauthorized remote monitoring and support utilities. ®
