• Chain Attacks: Involves exploiting multiple vulnerabilities in a sequence to breach defenses. Regular system patching and adopting a holistic security approach can prevent such layered threats.
• Watering Hole Attacks: Cybercriminals compromise a specific website known to be frequented by the target group, usually an organization. Regularly updating software and user training on safe browsing habits can offer protection.
• Spear Phishing: A targeted phishing attack aimed at a specific individual or organization. Regular employee training sessions and advanced email filtering tools can help recognize and combat such emails.
• SIM Swapping: Fraudulently transferring a person’s mobile number to a new SIM card, allowing attackers to access sensitive information. Using non-SMS-based two-factor authentication and regularly checking mobile account details can provide safety against it.
• Man-in-the-Middle Attacks: Interception and potential alteration of communication between two parties without their knowledge. HTTPS, encrypted communication, and VPNs can effectively deter such interceptions.
• Cryptojacking: Unauthorized use of someone’s device to mine cryptocurrency, often causing device slowdowns. Employing specialized anti-cryptojacking tools and regular system monitoring can help detect and prevent these covert mining activities.
• Drive-by Downloads: A method where malicious software is automatically downloaded onto a user’s system without their knowledge, often by just visiting a compromised website. Keeping all software updated, particularly web browsers, and utilizing web filters can offer substantial protection.
• Malvertising: Cybercriminals use legitimate online advertising networks to spread malware. Regular software updates and employing ad-blockers can help mitigate risks.
• Browser Fingerprinting: Techniques used to collect information about an individual’s browser type, settings, and plugins, aiming to track and identify the user without cookies. Using privacy-centric browsers and extensions can help obfuscate these details.
• Cross-Site Scripting (XSS): Attackers inject malicious scripts into websites that are viewed by other users. These scripts can then steal information or perform actions on their behalf. Regularly scanning and validating inputs can prevent such vulnerabilities.
• Cross-Site Request Forgery (CSRF): Attackers trick victims into performing actions without their knowledge on a web application where they’re authenticated. Implementing anti-CSRF tokens can help thwart these attacks.
• API Security Attacks: Cybercriminals exploit vulnerabilities in Application Programming Interfaces, which can lead to unauthorized data access. Regular audits, proper authentication, and monitoring can deter these threats.
• Server-Side Request Forgery (SSRF): Attackers manipulate server-side requests to read or interact with internal resources, potentially gaining unauthorized access. Proper input validation and filtering can offer protection.
• Distributed Denial of Service (DDoS): Multiple compromised systems are used to target a single system, causing a denial of service. Employing traffic filtering, network monitoring, and rate limiters can help mitigate these attacks.
• Container Security Exploits: As containerization (like Docker) becomes popular, vulnerabilities in container images and deployments are targeted. Regularly updating container software and monitoring runtime environments is essential.
• Insider Threats: These come from within the organization – disgruntled employees or negligent staff misusing their access. Regular audits, access controls, and employee training can significantly reduce risks.
• Evil Maid Attacks: This involves a physical attack where a device is tampered with while left unattended. For instance, a hotel room laptop left alone could be compromised. Protecting against this requires physical security measures, disk encryption, and ensuring devices are not left unguarded.
• Web Application Firewall (WAF) Bypass: WAFs are designed to filter and monitor HTTP traffic. When attackers circumvent a WAF, they can exploit web applications. Regular updates and stringent configurations for WAFs are essential.
• Bluetooth-based Attacks (e.g., BlueBorne): These attacks exploit vulnerabilities in Bluetooth protocols to compromise devices. Regularly updating device firmware and turning off Bluetooth when not in use can help guard against such exploits.
• Session Hijacking: This involves an attacker taking over a user’s session to gain unauthorized access to a protected area. Utilizing secure protocols and timely session timeouts can help mitigate this risk.
• URL Redirection Abuse: Cybercriminals exploit website redirection mechanisms to send users to malicious sites. Implementing strict parameter validation and ensuring that only known URLs are allowed can thwart this.
• Wireless Network Eavesdropping: Attackers listen in on wireless networks to capture sensitive data. Encrypting network traffic using robust protocols like WPA3 and regular monitoring can deter eavesdroppers.
• Kerberoasting: This involves extracting service account password hashes from Kerberos tickets. Implementing strong passwords and frequent password rotations can limit its effectiveness.
• Pass-the-Hash Attacks: Attackers use a stolen hash (rather than a password) to authenticate with a service. Solutions like restricting admin privileges, isolating services, and regular monitoring can be beneficial.
• Pass-the-Ticket Attacks: Similar to pass-the-hash, but attackers use Kerberos tickets instead. Ensuring tickets have a short life, coupled with regular monitoring, can help reduce this threat.
