Unit 42 demonstrates that root access on a Kubernetes node lets attackers spoof SPIFFE/SPIRE attestation and harvest co-located workloads' SVIDs.
Palo Alto Networks Unit 42 describes post-exploitation techniques in which an attacker with root on a compromised Kubernetes node spoofs Linux cgroup metadata used by the SPIRE agent during workload attestation, tricking it into issuing a co-located workload's SPIFFE Verifiable Identity Document to an attacker-controlled process. The research shows the core trust assumption of machine-identity systems—that the node is trusted—collapses once root is obtained, exposing all cryptographic identities scoped to that node. Unit 42 released an open-source tool, Spooffe, for defenders to test identity exposure, and notes the technique has not been observed exploited in the wild.
A comparison of twelve managed XDR providers covering pricing models, telemetry breadth, and distinguishing genuine MXDR from rebranded MDR services.
The article compares twelve managed XDR providers including Bitdefender, CrowdStrike, Palo Alto Unit 42, Trend Micro, Fortinet, Secureworks Taegis, Stellar Cyber, Ontinue, and ReliaQuest, highlighting pricing models and telemetry breadth. It explains that genuine MXDR must actively monitor identity, cloud, and email telemetry rather than merely ingest it, and typically costs 30-60% more than endpoint-only MDR. It also notes Sophos completed its approximately $859 million acquisition of Secureworks in February 2025.
Buyer's guide compares 12 XDR platforms, favoring Microsoft Defender XDR, Stellar Cyber and CrowdStrike, and warns ingestion pricing inflates costs.
The article compares 12 extended detection and response platforms, distinguishing native XDR (CrowdStrike, Palo Alto Cortex XDR, Microsoft Defender XDR, SentinelOne) from open XDR (Stellar Cyber, Arctic Wolf, Rapid7). It argues data ingestion pricing, not per-endpoint fees, is the main budget risk and should be modeled before signing. It repeats the consolidation note that Sophos acquired Secureworks for approximately $859 million in February 2025, and flags that ExtraHop is NDR rather than full XDR.
An editorial scorecard ranks 12 EDR platforms, with CrowdStrike and SentinelOne tied at 8.6/10 and telemetry retention identified as the hidden cost driver.
An editorial comparison scores twelve EDR platforms on detection, response, analyst burden, pricing transparency, and coverage. CrowdStrike and SentinelOne tie at 8.6/10, with Microsoft Defender for Endpoint close behind at 8.5 and described as effectively free in Microsoft 365 E5 estates. The guide argues that telemetry retention, not per-endpoint price, drives real cost, with fully-priced quotes frequently diverging 2-3x from headline rates. Managed detection offerings, including Cynet's bundled 24/7 SOC, factor into the buyer-fit rankings.

TrickBot phishing campaign used SendGrid, fake Google Docs, and Drive-hosted downloaders disguised as Word files to deliver a credential-stealing payload.
Unit 42 identified a TrickBot distribution campaign on November 7-8, 2019, using payroll and annual bonus-themed emails sent from likely compromised .edu addresses through the legitimate SendGrid email delivery service. Emails contained links to Google Docs documents linking to downloader executables hosted on Google Drive, further masked behind SendGrid click-tracking URLs. The downloaders, signed by PERISMOUNT LIMITED and displayed with Microsoft Word icons, show a decoy pop-up and retrieve TrickBot payloads from compromised legitimate domains such as savute[.]in and lindaspryinteriordesign[.]com. The newer TrickBot variant stores its files and configuration under %APPDATA%\cashcore.
Cortex XDR threat hunters uncovered a phishing campaign delivering the NetSupport Manager RAT via a fake password-protected NortonLifelock Word document.
Unit 42 identified a January 2020 phishing campaign using a Microsoft Word document disguised as a password-protected NortonLifelock file. Enabling macros triggered an obfuscated command that built alpaca.bat in the temp directory, which used msiexec to download an MSI payload from quickwaysignstx.com, filtered on the Windows Installer user-agent string. The payload installed a PowerShell script and the campaign, which has delivered NetSupport Manager RAT since at least 2018, showed related activity dating back to early November 2019.
Unit 42 assesses Ryuk ransomware amid a CISA/FBI/HHS alert on threats to U.S. healthcare, including the UHS attack that disrupted hospital operations.
A joint CISA, FBI, and HHS alert on October 28, 2020 warned of an imminent threat to U.S. healthcare from operators deploying Trickbot and Ryuk ransomware. Universal Health Services reported a Ryuk attack that disrupted all U.S. UHS sites for weeks, with similar incidents at hospitals in Oregon and New York. Ryuk typically arrives after Trickbot or BazaLoader infections delivered via malicious email, and operators enumerate networks with PowerShell and WMI before encryption. The Trickbot Anchor_DNS module performs DNS tunneling for C2, using connectivity checks to benign domains like ipinfo.io and checkip.amazonaws.com.
Unit 42 issued a threat brief on Maze ransomware, noting an uptick across industries and exploitation of Pulse VPN and IE flaws for initial access.
Palo Alto Networks detected an uptick in Maze ransomware samples across finance, healthcare, government, and other sectors. Maze, a variant of ChaCha ransomware first seen in May 2019, is distributed via weaponized Word/Excel attachments and the Spelevo exploit kit leveraging CVE-2018-15982 and CVE-2018-4878, and has used CVE-2019-11510 (Pulse VPN) and CVE-2018-8174 (Internet Explorer). Operators establish a foothold, escalate privileges, move laterally, and exfiltrate files before encryption for extortion leverage.
Unit 42 assesses Egregor ransomware, a Sekhmet variant likely run by former Maze affiliates using Qakbot, IcedID, and Ursnif for initial access.
Since September 2020, Unit 42 observed Egregor ransomware attacks across the U.S., Europe, Asia-Pacific, and Latin America, coinciding with the Maze team's shutdown announcement. Egregor, a variant of the Sekhmet family, uses commodity malware such as Qakbot, IcedID, and Ursnif for initial access, followed by scripts that modify firewalls, enable RDP, and deploy Cobalt Strike for reconnaissance and exfiltration. A PowerShell script uninstalls the McAfee agent and downloads the Egregor DLL via BITS, executed with the -passegregor10 key. Victims face a three-day ransom deadline before exfiltrated data is published on the Egregor Hall of Shame leak site.
Attackers actively exploit CVE-2025-32433, a CVSS 10.0 unauthenticated RCE in Erlang/OTP SSH, heavily targeting OT and critical infrastructure networks.
CVE-2025-32433 enables unauthenticated RCE in Erlang/OTP's SSH daemon via SSH connection protocol messages (codes >= 80) processed before authentication, affecting versions before OTP-27.3.3, OTP-26.2.5.11 and OTP-25.3.2.20. Unit 42 recorded a spike in exploitation between May 1-9, 2025, with 70% of detections on firewalls protecting OT networks, disproportionately affecting healthcare, agriculture, media and high technology. Observed payloads bind TCP-connected shells or launch Bash reverse shells to hosts like 146.103.40.203:6667, with randomized DNS lookups under dns.outbound.watchtowr.com indicating OAST-driven blind RCE validation.
Ukrainian government sites were defaced via OctoberCMS CVE-2021-32648 while Microsoft-attributed actor DEV-0586 deployed destructive WhisperGate malware.
Unit 42 tracks January 2022 attacks against Ukrainian government websites that were defaced or made inaccessible, which Ukraine attributed to Russia. Attackers exploited CVE-2021-32648, an account takeover flaw in OctoberCMS prior to 1.0.472, by submitting a boolean true as the password reset code to bypass validation. Separately, WhisperGate malware, attributed by Microsoft to DEV-0586, disabled Windows Defender and corrupted files across multiple Ukrainian organizations, using a ransomware-appearing first stage and an HTTPS-beaconing second stage with LOLBINs and anti-analysis techniques.
Unauthenticated Confluence RCE CVE-2022-26134 was exploited in the wild; Volexity observed intrusions and Cerber ransomware on unpatched servers.
Volexity identified exploitation of CVE-2022-26134, an unauthenticated remote code execution vulnerability in Atlassian Confluence Server and Data Center, during Memorial Day weekend 2022, with Atlassian issuing a patch. Cortex Xpanse found 19,707 potentially affected Confluence instances, concentrated in the US, Germany, China, and Russia, plus 1,251 end-of-life versions exposed. Unit 42 and Cortex Managed Threat Hunting observed successful exploitation leading to reconnaissance commands and a Cerber ransomware deployment that was blocked by Cortex XDR. A public PoC has increased exploitation risk.
Trojanized 3CXDesktopApp installers for Windows and macOS loaded RC4-encrypted shellcode delivering a backdoor to hundreds of thousands of 3CX users.
Threat actors compromised the 3CXDesktopApp build process, adding malicious libraries (ffmpeg.dll, d3dcompiler_47.dll) to installers downloaded from the developer's website. The Windows MSI loader decrypts embedded shellcode with RC4, sleeps for a random 1-4 weeks, then beacons to C2 hidden in icon files on GitHub. Unit 42 fingerprinted 247,277 IPs across 199 countries using 3CX applications and blocked shellcode execution at 127 Cortex XDR customers between March 9-30, 2023.
Unauthenticated Arbitrary File Read in Ivanti Pulse Connect Secure VPN
Ivanti Pulse Connect Secure, an enterprise SSL VPN appliance, contains an arbitrary file read vulnerability (CWE-22, path traversal) that requires no authentication. An unauthenticated remote attacker with network access to the appliance over HTTPS can send a specially crafted URI containing traversal sequences to read arbitrary files from the device. The attacker gains access to sensitive appliance files, potentially including configuration or credential material useful for further compromise, and CISA records known ransomware use of this flaw. Any organization running Pulse Connect Secure, especially gateways exposed to the internet for remote access, is affected. Exploitation is established: CISA added the flaw to its Known Exploited Vulnerabilities catalog on 2021-11-03 with known ransomware use, EPSS assigns a 100% probability of exploitation in the next 30 days, and no public PoC is known.
CVE-2025-32433 is a missing-authentication flaw (CWE-306) in the SSH server shipped with Erlang/OTP, the runtime and libraries of the Erlang programming language. An unauthenticated attacker can send specially crafted SSH protocol messages to a vulnerable Erlang/OTP SSH daemon before authentication and trigger remote code execution. Successful exploitation yields arbitrary command execution on the host with the privileges of the SSH service, and the CVSS scope change (S:C) indicates compromise can cascade to resources beyond the vulnerable component. Affected are any systems exposing the Erlang/OTP SSH server, including standalone Erlang deployments, Debian-packaged Erlang, and Cisco products that embed Erlang/OTP (e.g., Network Services Orchestrator, ConfD Basic, Ultra Packet Core). Exploitation is confirmed in the wild: a public proof-of-concept exists, the bug was added to CISA KEV on 2025-06-09, and researchers report a surge in exploitation attempts, with roughly 70% of observed attacks targeting OT firewalls.

Unauthenticated OGNL Injection RCE in Atlassian Confluence Server/Data Center
Atlassian Confluence Server and Data Center contain an unauthenticated remote code execution flaw caused by improper neutralization of expression-language (OGNL) input (CWE-917): an attacker with network access to the application can submit a crafted request that is evaluated as an expression and executed by the server. Successful exploitation lets a remote, unauthenticated attacker run arbitrary code with the privileges of the Confluence process, without any credentials. All organizations running self-managed Confluence Server or Data Center are affected, particularly instances exposed to the internet; Confluence Cloud is not listed among the affected products. Exploitation is confirmed in the wild: the flaw was added to CISA's KEV on 2022-06-02 with ransomware use marked as known, and EPSS assigns a 100% probability of exploitation within 30 days (100th percentile). CVSS has not yet been scored in this data, but the KEV listing and known ransomware use make unpatched, internet-facing instances a top-priority patching target.

Authentication Bypass in October CMS Password Reset Enables Account Takeover
October CMS, a content management system built on the Laravel PHP framework, contains an improper authentication flaw (CWE-287) in its october/system package: an attacker can initiate a password reset for any account and then submit a specially crafted request that bypasses the reset-code check, gaining access to that account without knowing the current password. The flaw is network-exploitable with no privileges or user interaction required (CVSS 3.1: 9.1, critical), and takeover of a back-end administrator account would grant the attacker full control of the CMS's content, users, and configuration. Any October CMS deployment running october/system versions prior to Build 472 or v1.1.5 is affected. Exploitation is confirmed in the wild: CISA added CVE-2021-32648 to its Known Exploited Vulnerabilities Catalog on 2022-01-18 as part of a batch of 17 added flaws, requiring patching per vendor instructions, and EPSS assigns a 90.4% probability of exploitation within 30 days (100th percentile). CISA lists ransomware use as unknown, and no public proof-of-concept exploit is known.

Use-After-Free RCE in Adobe Flash Player before 28.0.0.161
CVE-2018-4878 is a use-after-free (CWE-416) in Adobe Flash Player before 28.0.0.161, caused by a dangling pointer in the Primetime SDK's media-player handling of listener objects. An attacker triggers it by persuading a user to open attacker-controlled Flash content — typically a malicious SWF delivered via email, Office documents, or malvertising/exploit kits — because the CVSS vector (AV:L, UI:R) requires local user interaction. Successful exploitation yields arbitrary code execution with the privileges of the user running Flash. Anyone running a vulnerable Flash Player was exposed, including Red Hat Enterprise Linux Desktop/Server/Workstation users running Red Hat's packaged Flash plugin. The flaw was exploited as a zero-day in January–February 2018 (documented by McAfee and distributed alongside the Fallout exploit kit), and it remains in CISA's KEV with known ransomware use.

CVE-2018-15982 is a use-after-free flaw (CWE-416) in Adobe Flash Player versions 31.0.0.153 and earlier, and 31.0.0.108 and earlier, in which Flash frees memory that is subsequently reused, corrupting process memory. It is triggered when Flash processes crafted Flash content, most notably embedded in Microsoft Office documents, requiring a user to open or view the malicious content (CVSS attack vector is local with user interaction required). Successful exploitation gives the attacker arbitrary code execution with the privileges of the user viewing the content. Affected users include anyone running the listed Flash Player versions, including the Flash Player Installer and the Adobe-supplied Flash plugin shipped with Red Hat Enterprise Linux Desktop, Server and Workstation. Exploitation is confirmed in the wild: the flaw is in CISA's Known Exploited Vulnerabilities catalog (added 2022-02-15) with known ransomware use, a public exploit is available on Exploit-DB, and EPSS assigns a top-percentile 89.1% probability of exploitation within 30 days.

Out-of-Bounds Write RCE in Microsoft Windows VBScript Engine
CVE-2018-8174 is an out-of-bounds write (CWE-787) in the Microsoft Windows VBScript engine, caused by the way it handles objects in memory. An attacker triggers it by convincing a user to visit a specially crafted website or open crafted content that invokes the VBScript engine (for example via Internet Explorer or a document preview), requiring user interaction. Successful exploitation yields remote code execution with the privileges of the logged-on user, enabling program installation, data theft and account takeover. All listed Windows client and server releases are affected: Windows 7, 8.1, RT 8.1, Windows 10 (1607-1803), and Windows Server 2008/2008 R2, 2012/2012 R2, 2016. Exploitation is in the wild: the flaw was fixed in the May 2018 Patch Tuesday, is listed in CISA KEV with known ransomware use, and public PoCs (0patch, ExploitDB 44741) and exploit kit usage have been documented; EPSS puts its 30-day exploitation probability at 88.5%.
