How Do You Get Malware?

Many people are fretting over thoughts, like “cybercriminals use which method the most?” or “what is a primary method a hacker uses to break into your computer?” If you find yourself in the same boat, don’t worry! We have shortlisted some of the most common ways you may get infected with malware and how to avoid them:

Phishing

Phishing represents a sophisticated form of social engineering where attackers assume the identity of a trusted entity, intending to dupe the target into divulging sensitive information or unwittingly installing malware. Although phishing attacks predominantly manifest through email, with an astonishing 3.4 billion phishing emails sent daily, they can also materialize via text messages, social media applications, and phone calls.

The deceptive tactics employed in phishing are diverse. Often, attackers send emails mimicking trusted sources like banks, government agencies, or major e-commerce platforms, urging recipients to click on links or download attachments. Such actions trigger the download and execution of malware, compromising the target’s security.

Phishing campaigns vary in their approach to target selection. Traditional phishing attacks cast a wide net, distributing fraudulent messages to thousands or millions of individuals. In contrast, spear phishing is more discerning, focusing on specific members of an organization to access high-value data. Whaling attacks take selectivity a step further, honing in on high-ranking individuals with elevated access to sensitive information.

How to Prevent Phishing Attacks

Web Filtering: Web filtering serves as a proactive cybersecurity measure to thwart phishing attacks by restricting access to known malicious websites. Anti-malware boasts an extensive database curated from public lists, verified user submissions, and collaborations with specialized intelligence organizations. This dynamic database undergoes continual updates, ensuring users are shielded from the latest phishing threats. When a user attempts to access a malicious site, anti-malware intervenes, blocking the connection and averting the exchange of sensitive data.

Staff Training: Staff training emerges as a potent line of defense against phishing, leveraging education to counteract human vulnerabilities exploited by such attacks. A comprehensive approach involves training personnel at all organizational levels to identify potential phishing scams, emphasizing indicators like typos, grammatical errors, misspelled URLs, and unsolicited email attachments. Clearly documented escalation processes empower staff to promptly report suspicious emails and phishing incidents, enabling IT teams to respond effectively and track evolving phishing patterns. Given the dynamic nature of phishing techniques, regular training sessions ensure teams remain adept at recognizing and thwarting the latest tactics.

Email Authentication: Email authentication protocols enhance security by verifying the legitimacy of emails and safeguarding against tampering. Businesses can employ several protocols:

• Sender Policy Framework (SPF): Empowers domain owners to specify authorized IP addresses for email transmission.
• DomainKeys Identified Mail (DKIM): Utilizes digital signatures to verify that an email originated from an authorized sender and remained unaltered during transit.
• Domain-based Message Authentication, Reporting and Conformance (DMARC): Enhances SPF and DKIM by providing robust email authentication. DMARC allows domain owners to define actions for emails that fail SPF or DKIM checks, reinforcing the integrity of email communications.

Compromised Credentials

Threat actors employ diverse methods to acquire login credentials, showcasing their adaptability and cunning strategies. They may procure passwords from the dark web through illicit transactions or employ deception by tricking users into divulging their credentials on phishing sites meticulously designed to mimic reputable organizations’ websites. Another covert approach involves the installation of keyloggers on systems, silently recording keystrokes, while a more forceful tactic entails brute force attacks. In this scenario, automated tools systematically attempt every conceivable character combination until the password is successfully cracked.

Once login credentials are compromised, threat actors gain unrestricted access to the privileges associated with the compromised account. The aftermath of such breaches can take various forms; some attackers may promptly deploy malware for immediate impact, while others adopt a patient approach. This patient strategy involves gradually escalating privileges, moving laterally within the network, and meticulously preparing the environment to maximize the overall impact of their impending attack.

How to Keep Credentials Secure

Implementing robust security measures is essential in safeguarding against unauthorized access and potential breaches. Here are key strategies:

Two-Factor Authentication (2FA): Elevating security, 2FA mandates users to provide two forms of authentication, typically a password and a code sent via text message or generated by an app. Even if a staff member’s credentials are compromised, threat actors cannot access the account without the secondary form of authentication, fortifying account protection.

Password Managers: Managing numerous usernames and passwords can be challenging, leading individuals to reuse passwords across multiple accounts. This poses a significant risk, as compromise of one account can potentially grant access to others. To address this, promoting the use of trusted password managers enables secure storage of passwords in a centralized, protected space, reducing the risk of unauthorized access.

Principle of Least Privilege: Adhering to the principle of least privilege is a foundational security concept that entails granting users the minimum level of access necessary for their job functions. Each user account should possess only the essential permissions and access required for specific tasks, limiting the potential impact of a security incident. In the event of compromised login credentials, attackers are constrained to the systems and data associated with the user’s permissions, mitigating potential damage.

Exploit Kits

An exploit kit serves as a sophisticated toolkit employed by threat actors to identify and exploit known security vulnerabilities within client-side software, encompassing the operating system, browser, and other applications. Upon detecting a security flaw, the exploit kit seamlessly deploys tailored malware crafted to capitalize on the specific vulnerability.

Typically, threat actors host exploit kits on compromised websites, creating a perilous environment for unsuspecting users. When a user accesses such a compromised website, the exploit kit initiates a comprehensive scan of the system, automatically attempting to exploit any detected vulnerabilities. This automated process is integral to the drive-by download technique, a distinctive characteristic of exploit kit attacks. Remarkably, drive-by downloads do not necessitate any user-initiated action; merely visiting the compromised website is sufficient to trigger the infection chain, resulting in the user becoming unwittingly infected with malware.

How to Avoid Exploit Kits

Ensuring the security of your system involves adopting proactive measures:

Apply Updates: Counteract potential threats by promptly applying important security updates. Exploit kits often target known security vulnerabilities that have already been addressed. Regular patch management is crucial, as the longer you delay installing security updates, the greater the risk of falling victim to exploits.

Harden Your System: Optimize your system’s security posture by streamlining software installations. Limit installed software to what is essential for each individual’s job function. Conduct a thorough audit of your current software stack, eliminating unnecessary applications, including extraneous browser extensions, and superfluous system tools. By adopting a lean and purposeful software environment, you reduce potential entry points for exploitation, enhancing overall system resilience.

Compromised Managed Service Providers

Managed Service Providers (MSPs) emerge as appealing targets for cybercriminals due to their role in remotely overseeing the IT infrastructure of numerous clients. Successfully compromising a single MSP provides threat actors with a gateway to the networks of the MSP’s entire client base. Leveraging the MSP’s infrastructure, especially tools like remote monitoring and management (RMM) software, allows cybercriminals to efficiently deploy malware across multiple targets simultaneously.

Given the substantial repercussions of a compromise, MSPs are compelled to institute robust security measures to safeguard both themselves and their clients. This entails the implementation of multi-factor authentication, vigilant monitoring for anomalous activities, and regular execution of security audits and vulnerability scans. In addition to preventive measures, MSPs must establish a comprehensive incident response plan, ready to be activated in the event of a security breach. This holistic approach is crucial to fortify MSPs against cyber threats and mitigate potential cascading impacts on their client networks.

How to Mitigate Malware Delivered Through MSPS

Be Selective: Exercising discretion in your choices is crucial, especially when deciding on software vendors that directly impact the security, data integrity, and reputation of your business. Therefore, adopt a selective approach. When evaluating a potential Managed Service Provider (MSP), engage in open discussions about your concerns. Inquire about their credentials, scrutinize their track record, and assess the presence of an incident response plan. Seek clarity on their alignment with frameworks or compliance structures and the frequency of security process audits. Formalize these details in written service agreements to establish and uphold stringent cybersecurity standards with your suppliers.

Use 2FA on RMM Software: Strengthen the security of your Remote Monitoring and Management (RMM) software by implementing Two-Factor Authentication (2FA). Although not foolproof, 2FA serves as a straightforward and effective measure to significantly diminish the risk of a security breach arising from compromised RMM software. By integrating 2FA into your security protocols, you add an additional layer of protection, reinforcing your defenses against potential threats.

Pirated Software

Engaging in the use of pirated software not only constitutes an illegal practice but also exposes users to a pervasive and varied array of malware threats. Malicious actors frequently leverage pirated software as a conduit for distributing an extensive range of malware, encompassing keyloggers, ransomware, trojans, backdoors, cryptojackers, adware, and more.

In certain instances, the pirated software may outwardly function as advertised, concealing the delivery of a malicious payload in the background. Alternatively, threat actors may fabricate counterfeit versions of popular software, devoid of any legitimate function, with the sole purpose of infecting users with malware. Notably, even authentic software can, at times, be bundled with malware or potentially unwanted software, underscoring the inherent risks associated with the use of unverified or illicit software sources.

How to Avoid Pirated Software Malware Infections

Avoid Pirated Software: Steer clear of pirated software – the risks far outweigh any perceived benefits. Beyond the immediate threat of malware infections, pirated software commonly lacks timely updates, leaving your applications susceptible to potential exploits without crucial security patches. The abundance of freeware and freemium alternatives makes it illogical to resort to pirated software.

Don’t Even Browse: Exercise caution in your online activities by refraining from browsing websites that host pirated software. These sites are often inundated with deceptive ads that can redirect users to malicious websites or entice them into unwittingly downloading and installing malware. It’s in your best interest to avoid these hazardous online spaces entirely.
