As digital transformation accelerates across every industry, it brings along an exponential rise in cyber threats. Attackers today have access to more lethal hacking tools, easier monetization avenues, and even dark web marketplaces to purchase vulnerabilities and malware.
Meanwhile, vast amounts of sensitive data, mission-critical infrastructure and essential services have moved online – expanding the attack surface. Between crippled operations, stolen IP, negative publicity and legal liabilities from data breaches, cyberattacks pose an existential threat to businesses in 2023.
As per reports, cybercrime will inflict damages totaling $10.5 trillion annually by 2025. But with the right understanding of adversary tactics and cyber resilience strategies, you can secure your organization against most threats.
In this comprehensive guide, I have condensed 18 most high-risk threats under 6 categories that decision markers and tech teams must be aware of:
Malware Attacks
1. Ransomware
Ransomware encrypts your files and blocks access to core systems until you pay hefty ransoms. Through networks of affiliates, groups like REvil perfected extortion models making it the top threat.
Impact: Loss of data access bringing business operations to halt coupled with ransom demands averaging $170k per event
2. Wipers
Destructive malware that completely deletes data and wipes storage drives clean, causing maximum service disruption during conflicts between nation states.
Impact: Total and permanent loss of mission-critical data assets and infrastructure shutdown
3. Botnets
Botnets infect a network of devices and co-opt them via C2 channels to launch cyber attacks ranging from DDoS to malware campaigns at scale. Highly resilient botnets stay under the radar for months together.
Impact: Your company resources getting hijacked to facilitate large scale cybercrime. Also leads to data theft or accessibility issues.
4. Trojans
Malware masked as legitimate apps that allows adversaries remote access to devices once executed. Used as stepping stone for lateral movement within networks.
Impact: Corporate espionage by nation-state actors, loss of complete device control, data exfiltration through covert channels
Web & App Threats
5. Phishing
Phishing tricks employees into sharing passwords or opening weaponized attachments via spoofed emails to deliver first-stage payloads. Ranging from Target to LinkedIn, it contributed to 90% of breaches in the last decade.
Impact: Password compromise provides easy gateway for attackers into networks culminating in data theft or ransomware
6. Supply Chain Attacks
By hacking trusted third-party suppliers and vendors, adversaries breach the target organization‘s network through these supply chain relationships without raising alarms.
Impact: Access to sensitive information through supply chain allows attackers larger attack surface persisting for months
7. SQL Injection
Exploiting vulnerabilities in web app code, SQL injection inserts malicious database queries granting access to entire tables containing PII, financial or healthcare records. Over 65% of web apps contain flaws prone to this technique.
Impact: Depending on compromised data sensitivity, this can lead to major compliance violations amounting to legal penalties and lawsuits
8. Cross-Site Scripting
Injecting malicious scripts into web apps allows XSS attacks to steal session tokens, cookies and other info to impersonate legitimate users. Over 20% of web breaches occur via XSS.
Impact: Account takeover, DDoS using stolen session identifiers
9. API Threats
APIs connect crucial business systems but contain vulnerabilities open to abuse. API keys leaked through code flaws are prime targets. Attackers exploit APIs to grab data, invoke destructive functions or exhaust usage quotas.
Impact: Data leaks, service disruption, business logic manipulation
Network & Endpoint Threats
10. Distributed Denial of Service (DDoS)
Flooding websites and networks with excess junk traffic, DDoS attacks overwhelm systems and prevent access for genuine users often causing prolonged outages.
Impact: Sustained downtime results in immense revenue and productivity loss along with reputational damage
11. Man-in-the-Middle (MitM)
By intercepting communications between two parties, MitM attackers can steal data or insert themselves into sessions to spread disinformation or malware.
Impact: Access to sensitive information, malware propagation to connected systems and users
12. Watering Hole
Watering hole attacks infect websites commonly visited by targets of interest to launch further attacks once users land on the rigged sites unknowingly.
Impact: Mass compromise of sensitive accounts, trade secret theft, espionage
13. Insider Threats
Insiders like employees, ex-staff or third party vendors abuse privileged access to exfiltrate data, sabotage systems or sell secrets causing over 30% of breaches.
Impact: IP and trade secret theft, leaking customer PII
14. Fileless Malware
Living purely in memory without traditional executable files on disk, fileless malware use native OS tools like Powershell and BAT scripts to breach air-gapped networks.
Impact: Bypasses legacy defenses, persistent threats in critical infrastructure like ICS
Emerging Attack Trends
15. IoT/OT Attacks
From hijacked cameras to attacks on manufacturing equipment, unsecured IoT and OT devices provide gateways into corporate networks for lateral movement.
Impact: Critical infrastructure at grid, utilities can be disrupted
16. Cloud Threats
Misconfigurations in cloud platforms lead to data leaks or resource hijacking for crypto mining. Breaches via cloud storage jumped by over 630% in 2022.
Impact: With industries migrating business apps to cloud, this expanding attack surface poses major risk
17. Password Attack Trends
Password spray, brute force and other password attack tools leverage compromised credential lists from past breaches to break into accounts. Over 80% of login attempts come from password stuffing scripts.
Impact: Quick account takeover, privilege escalation within networks
18. Cryptojacking
Cryptojacking scripts mine cryptocurrency using stolen compute resources from cloud servers, user devices and more recently Kubernetes clusters.
Impact: Slow system performance, rising energy costs
Charting The Surge in Threats
With tens of thousands of vulnerabilities identified each year in business software and networks growing more complex, the attack surface is infinite for threat actors in 2023. Understanding the typical intrusion kill chain and common attack patterns is vital to securing infrastructure.
While motivated hackers will always attempt to breach defenses, organizations can significantly minimize business impact through cyber resilience – which emphasizes detection and response over relying just on prevention tools. Let‘s examine key measures under the umbrella of cyber resilience to thwart threats at each stage.
Building Cyber Resilience for the Modern Threat Landscape
Secure Foundations through Best Practices
- Keep software, systems and services updated with latest patches
- Only grant employee access to company data and resources on a need-to-know basis
- Enforce strong password policies and multi-factor authentication everywhere
- Build security into coding practices through DevSecOps pipelines
- Maintain data backups offsite as last line of defense against destructive attacks
- Continuous end-user education around latest threat trends
Visibility Across Infrastructure
- Unified SIEM platform for alerts and threat intel
- Endpoint detection on devices, servers
- Behavior analytics identifying anomalies
- Network traffic inspection for IOCs
- Cloud security posture management
Timely Threat Detection
- Managed detection and response able to contextualize alerts
- Deception tools like honeypots distracting attackers
- Threat hunting uncovering hidden risks
- Breach attack simulation assessing team readiness
Incident Response
- Dedicated response plans with assigned roles to contain breaches faster
- Playbooks guiding actions during different attack types
- Forensics after incidents help identify root causes and enhance defenses
Compliance Mandates
- Data security controls meeting HIPAA for healthcare firms
- Regular audits required under PCI DSS for payment processors
Zero Trust Access
- Least privilege permissions to apps, data
- Strict verification enforcing user identity validation
- Microsegmentation limiting lateral movement risks
In Summary
While the cyberthreat landscape will only intensify going forward, becoming an elusive target focused on resilience rather than elimination provides the strategic edge. By investing in robust security tailored to address these 18 high-risk threats and following cyber resilient practices, you can mitigate potential business impact substantially.
