11 Feb The Infostealer Epidemic: Protecting Your Business from the Latest Wave of Cyberattacks
Data is the new gold. Customer information, financial records, proprietary designs, and strategic plans are all valuable assets that drive business growth and success. But this valuable data is also under constant threat from cybercriminals who seek to exploit vulnerabilities and steal information for their own gain. Among the growing arsenal of cyber threats, infostealer malware stands out as a particularly insidious and pervasive danger.
Infostealer malware, as its name suggests, is designed to stealthily infiltrate your systems and siphon off sensitive data. It lurks in the shadows, often undetected by traditional malware protection software for business, quietly collecting login credentials, credit card numbers, personal information, and other valuable data. This stolen information can then be used for identity theft, financial fraud, or further cyberattacks, causing significant financial losses and reputational damage to businesses. The rise of remote work, the increasing use of personal devices for business purposes, and the growing sophistication of infostealer malware have created a perfect storm, leading to a veritable epidemic of data breaches and compromised accounts.
This post delves into the world of infostealer malware, exploring its insidious nature, the methods used to spread it, and the devastating impact it can have on businesses. More importantly, we’ll equip you with the knowledge and strategies to protect your business from this growing threat and safeguard your valuable data.

Understanding the Infostealer Threat
Infostealer malware is a broad category of malicious software designed to steal sensitive information from infected computers and devices. These stealthy programs often operate in the background, evading detection by traditional antivirus software, while quietly collecting a treasure trove of data. Let’s take a look at some infamous examples of infostealer malware.
FormBook
A notorious infostealer that emerged in 2016, FormBook is known for its ability to steal data from web browsers, email clients, and other applications. It has been used in numerous large-scale cyberattacks, targeting businesses and individuals worldwide.
TrickBot
Another prevalent infostealer, TrickBot is often spread through phishing emails and malicious websites. It is capable of stealing a wide range of information, including banking credentials, login details, and system information. TrickBot has been used in various cybercrime campaigns, including ransomware attacks and financial fraud.
Zeus
One of the earliest and most widespread infostealers, Zeus emerged in 2007 and quickly gained notoriety for its ability to steal banking credentials and other sensitive data. It has been used in numerous cyberattacks, resulting in significant financial losses for individuals and businesses.
Agent Tesla
A remote access trojan (RAT) with infostealer capabilities, Agent Tesla can steal data from various sources, including keystrokes, clipboard contents, and screenshots. It has been used in targeted attacks against businesses and individuals, often for espionage or financial gain.
RedLine Stealer
A relatively new infostealer that emerged in 2020, RedLine Stealer is known for its ability to steal data from web browsers, cryptocurrency wallets, and VPN clients.11 It has been used in various cybercrime campaigns, including ransomware attacks and the sale of stolen data on the dark web.
These are just a few examples of the many infostealer malware variants that have plagued businesses and individuals over the years. As you see, these stealthy programs can operate in the background, evading detection by traditional antivirus software, while quietly collecting a treasure trove of data.
- Usernames and passwords for email accounts, social media platforms, online banking, and other sensitive accounts.
- Credit card numbers, bank account details, and other financial data.
- Names, addresses, phone numbers, social security numbers, and other personally identifiable information (PII).
- Computer specifications, operating system details, and installed software.
- Websites visited, search queries, and online activity.
This stolen information can be used for a variety of malicious purposes. Attackers can use login credentials to access accounts and steal funds, make unauthorized purchases, or launch further attacks. Financial information can be used for identity theft, credit card fraud, or opening fraudulent accounts. Personal information can be sold on the dark web or used for targeted phishing scams and social engineering attacks.
How Infostealer Malware Spreads
Infostealer malware employs various tactics to infect computers and devices, often exploiting human vulnerabilities and leveraging social engineering techniques.
Phishing Emails
One of the most common methods of spreading infostealer malware is through phishing emails. These emails often appear to be from legitimate organizations or individuals, tricking recipients into clicking on malicious links or opening infected attachments. Once the recipient takes the bait, the malware is downloaded and installed on their device, often without their knowledge.
Malicious Websites
Visiting compromised or malicious websites can also lead to infostealer infections. These websites may contain hidden malware that is automatically downloaded and installed on your device when you visit the site. Drive-by downloads, where malware is downloaded without any user interaction, are a common tactic used on malicious websites.
Software Vulnerabilities
Outdated or unpatched software can contain vulnerabilities that attackers can exploit to install infostealer malware. This highlights the importance of keeping your operating system, applications, and security software up to date to protect against known vulnerabilities.
Social Engineering
Attackers often use social engineering tactics to manipulate individuals into downloading or installing infostealer malware. They may impersonate IT support personnel, colleagues, or even friends and family to gain trust and trick individuals into taking actions that compromise their security.
The Impact on Businesses
The consequences of an infostealer infection can be severe for businesses, leading to a range of disruptions, financial losses, and reputational damage.
Data Breaches and Financial Losses
Infostealer malware can lead to significant data breaches, exposing sensitive customer data, financial records, and intellectual property. This can result in financial losses due to fraud, legal liabilities, and regulatory fines. The cost of recovering from a data breach can be substantial, including the cost of investigating the breach, notifying affected individuals, providing credit monitoring services, and implementing remedial measures.
Operational Disruptions and Downtime
Infostealer infections can also disrupt business operations and lead to costly downtime. Malware can disrupt critical systems, disable services, or even render computers unusable. This can hinder productivity, disrupt customer service, and delay projects, impacting your bottom line and potentially damaging your reputation.
Reputational Damage and Loss of Trust
Data breaches and cyberattacks can severely damage a business’s reputation and erode customer trust. Customers may be hesitant to do business with a company that has suffered a data breach, fearing that their personal information might be compromised. This can lead to lost sales, decreased revenue, and difficulty attracting new customers. Rebuilding trust after a data breach can be a long and challenging process, requiring significant investment in reputation management and customer outreach.
Protecting Your Business from Infostealer Malware
Malware protection for business requires a multi-layered approach that combines technology, policies, and employee education.
Cybersecurity Solutions
Implement robust cybersecurity measures to protect your systems and data from unauthorized access and malware infections. This includes:
