💡 Did You Know - "Holiday Siege" Threat Landscape
Did you know that 76% of ransomware encryption events are timed to start after business hours to maximize dwell time?
Did you know that 60% of successful cyberattacks occur shortly after a major corporate event, such as a merger, acquisition, or layoff—all common in Q4?
Did you know that holiday-themed phishing emails (e.g., "HR: 2026 Benefits Enrollment," "Gift Card Bonus") increased by a staggering 692% in Q4 2025?
Did you know that the median ransom demand for the Retail sector has nearly doubled to $2 million this year due to the pressure of holiday sales uptime?
Did you know that 6% of organizations admit to having zero active SOC coverage during holidays, relying entirely on passive tools?
Did you know that "Encryption-less Extortion" (pure data theft) has tripled in the Healthcare sector this year, bypassing backup strategies entirely?
Did you know that GenAI-driven bot traffic on retail sites is predicted to surge 520% this month, creating "noise" that hides malicious reconnaissance?
🎯 STRATEGIC BRIEF
The "Holiday Siege" Phenomenon
52% of attacks happen on holidays + React2Shell Critical Zero-Day
The Issue:
New data confirms that 52% of ransomware attacks now occur specifically on holidays or weekends. Simultaneously, 44% of organizations reduce their SOC staffing by 50-70% during the December break. This creates a "defense gap" that adversaries have industrialized.
The Opportunity:
The era of the "Skeleton Crew" is over. We must shift from reliance on human vigilance to Automated Resilience.
Why It Matters:
Attackers know your "Time to Detect" (TTD) skyrockets when staff are OOO. They use this window to exfiltrate massive datasets before encrypting, ensuring leverage even if you have backups. In 2025, a holiday breach isn't just an outage; it's a guaranteed double-extortion event.
The Playbook:
Lower Automation Thresholds: Temporarily configure your EDR/SOAR to "Block/Isolate" aggressively on high-fidelity alerts. It is better to accidentally isolate a laptop than to let ransomware spread while an analyst is at dinner.
Delegate Authority: Ensure the junior staff covering the holiday shift have the explicit authority to make major decisions (like severing an internet connection) without needing C-level approval.
No Patch Freezes: Do not confuse a "Code Freeze" (no new features) with a "Patch Freeze." Security patching must continue through December 31st.
Cybersecurity is no longer just about prevention—it’s about rapid recovery and resilience!

Remember when software made business simpler?
Today, the average company runs 100+ apps—each with its own logins, data, and headaches. HR can’t find employee info. IT fights security blind spots. Finance reconciles numbers instead of planning growth.
Our State of Software Sprawl report reveals the true cost of “Software as a Disservice” (SaaD)—and how much time, money, and sanity it’s draining from your teams.

📡 THREAT RADAR - Rapid Intelligence - Active Threats
eact2Shell (CVE-2025-55182):
Risk: Critical (CVSS 10.0). Unauthenticated Remote Code Execution.
Impact: Attackers can execute arbitrary code on servers running Next.js or React Server Components via a single HTTP request. Active exploitation confirmed.
Action: Patch
reactto v19.0.1+ andnextto v15.0.5+ immediately. Do not wait for the New Year.
Array Networks VPN (CVE-2025-66644):
Risk: Critical. OS Command Injection.
Impact: Attackers are planting webshells on VPN gateways to gain persistent entry, specifically targeting remote workers.
Action: Patch to ArrayOS AG 9.4.5.9+. CISA has mandated this patch by Dec 29—treat it as an emergency.
Rhysida Ransomware:
Risk: Healthcare Sector Targeting.
Impact: This group is auctioning stolen patient data on the dark web rather than just encrypting it.
Action: Audit all external-facing remote services (RDP/VPN) and enforce phishing-resistant MFA on every account, no exceptions.
🛠️ THE TOOLKIT - Solutions to Modern Problems.
The Agentic Responder: Torq HyperSOC
Problem: Slow response times when human analysts are on holiday leave.
Solution: Uses AI agents to autonomously investigate and contain high-volume, low-fidelity alerts, ensuring coverage without burning out your skeletal staff.
The Config Watchdog: Mondoo
cnspecProblem: "Shadow IT" and misconfigurations often slip in during the end-of-year rush.
Solution: Runs rapid, policy-as-code scans across your cloud and on-prem infrastructure to detect drift before attackers exploit it.
The Automated Hunter: CrowdStrike Charlotte AI
Problem: Complex threat hunting requires senior staff who are likely on vacation.
Solution: Allows junior analysts to ask plain-language questions ("Show me all connections to IP X") and automates the complex queries required to find hidden threats.

📊 C-SUITE SIGNAL - Key Talking Points For Leadership
Regulatory Liability: New NYDFS Part 500 regulations now mandate strict asset inventory and MFA. Why: A breach during the holidays is no longer just an operational failure; it is a compliance violation with potential fines hitting in Q1 2026.
The "Winter Grid" Risk: The Department of Energy has flagged cyber-physical threats to the energy grid as a priority. Why: If your disaster recovery plan assumes power is always available, you need to update it for a scenario where a cyberattack hits the utility provider during a winter storm.
🧠 BYTE-SIZED FACT
The two most impactful vulnerabilities of the last decade: SolarWinds (Dec 8, 2020) and Log4j (Dec 9, 2021) were both disclosed exactly during this week in December.
The Lesson: The "December Surprise" is a historical pattern, not a myth. Maintain full incident response readiness through Dec 15th.
