Cybercriminals modus-operandi, Reporting of cybercrimes, Remedial and Mitigation measures

Understanding the modus Operandi of cybercriminals is crucial in developing effective cybersecurity strategies. Cybercriminals employ a variety of techniques to compromise systems, steal sensitive information, and exploit vulnerabilities.

Phishing:

Phishing is a deceptive technique where cybercriminals use emails, messages, or websites that mimic legitimate entities to trick individuals into divulging sensitive information such as login credentials, financial details, or personal information.

• Tactics: Phishing emails often contain urgent messages, fake links, or malicious attachments designed to lure recipients into taking actions that benefit the attacker.

Ransomware Attacks:

Ransomware is a form of malicious software that encrypts files or systems, rendering them inaccessible. Cybercriminals then demand a ransom payment, usually in cryptocurrency, for the decryption key.

• Tactics: Ransomware is often delivered through phishing emails, malicious attachments, or exploiting vulnerabilities in software. Once activated, it encrypts files and displays a ransom message.

Malware Distribution:

Malware, short for malicious software, includes viruses, Trojans, worms, and other types of harmful software. Cybercriminals use malware to compromise systems, steal data, or disrupt operations.

• Tactics: Malware is distributed through infected websites, malicious email attachments, or compromised software. It can exploit vulnerabilities in software or rely on social engineering to trick users into executing it.

Business Email Compromise (BEC):

BEC attacks involve compromising business email accounts, often those of executives, to conduct fraudulent activities. This may include unauthorized fund transfers or sensitive information theft.

• Tactics: Cybercriminals use social engineering, phishing, or malware to gain access to business email accounts. Once compromised, they can monitor communications and orchestrate fraudulent transactions.

Credential Stuffing:

In credential stuffing attacks, cybercriminals use username and password combinations obtained from previous data breaches to gain unauthorized access to user accounts on various platforms.

• Tactics: Automated tools are employed to test large sets of credentials across multiple websites, exploiting the tendency of users to reuse passwords across different accounts.

Distributed Denial of Service (DDoS) Attacks:

DDoS attacks overwhelm a target’s online services by flooding them with traffic, causing disruption or downtime.

• Tactics: Cybercriminals often use botnets—networks of compromised computers—to launch massive volumes of traffic at a target’s servers, making it difficult for legitimate users to access services.

Man-in-the-Middle (MitM) Attacks:

In MitM attacks, cybercriminals intercept and potentially alter communications between two parties without their knowledge.

• Tactics: Attackers may achieve this by eavesdropping on unsecured networks, deploying rogue Wi-Fi hotspots, or using techniques like session hijacking to gain unauthorized access to sensitive information.

Advanced Persistent Threats (APTs):

APTs are long-term targeted attacks where cybercriminals gain unauthorized access to a network and remain undetected for an extended period, often to steal sensitive information or conduct espionage.

• Tactics: APTs involve sophisticated techniques, including zero-day exploits, social engineering, and lateral movement within a network to maintain persistence.

Cryptojacking:

Cryptojacking involves using a victim’s computing resources without their knowledge to mine cryptocurrencies. This can lead to reduced system performance and increased energy consumption.

• Tactics: Cybercriminals may infect websites with malicious scripts or distribute malware that hijacks the processing power of users’ devices to mine cryptocurrencies.

Supply Chain Attacks:

Supply chain attacks target vulnerabilities in the software supply chain to compromise the integrity of software or hardware before it reaches end-users.

• Tactics: Cybercriminals may compromise software updates, inject malicious code into legitimate applications, or compromise hardware components during the manufacturing process.
