The first version of Kaspersky Lab's antivirus software was developed by Eugene Kaspersky in 1989 in response to the Cascade Virus. Early versions had just 40 virus definitions and were mostly distributed to friends and family members. Kaspersky continued developing the software at KAMI, resulting in the AntiViral Toolkit Pro (AVP) product released in 1992. It was popularized in 1994 after a competitive analysis by Hamburg University gave his software first place.
In 1997, Eugene Kaspersky, his wife Natalya Kaspersky, and Alexey De-Monderik left KAMI to form Kaspersky Lab, and to continue developing the antivirus product, then called AVP. The product was renamed Kaspersky Anti-Virus after an American company registered the AVP trademark in the US.
By 2013, the company had an unaudited $667 million in annual revenues. In 2014, Kaspersky Lab signed a distribution deal with Ingram Micro, which significantly expanded its reseller program.
In August 2015, two former Kaspersky employees alleged that the company introduced modified files into the VirusTotal antivirus database to trick software from Kaspersky competitors into triggering false positives in virus and malware scans. A possible motive is that Eugene Kaspersky allegedly was furious at competitors perceived to be "unfairly" free-riding on Kaspersky's malware discoveries via the open-source VirusTotal database. The company denied the allegations. On his personal blog, Eugene Kaspersky compared the accusations to unsubstantiated conspiracy theories. Reuters followed up by publishing leaked emails allegedly from Kaspersky alluding to "falsies" and "rubbing out" foreign competitors; Kaspersky Lab stated the emails "may not be legitimate and were obtained from anonymous sources that have a hidden agenda".
In 2016, Kaspersky executive Ruslan Stoyanov was arrested by Russian authorities on charges predating his work at Kaspersky. In 2019, he was convicted of treason.
In June 2023, Kaspersky Lab said many of its senior staff and managers were hit by an ongoing attack that it first suspected in early 2023 and has compromised thousands of iPhones. The oldest traces of infection date back to 2019. The Russian Federal Security Service (FSB) separately accused the US National Security Agency and company Apple of being behind the attack and infiltrating the phones of diplomats from China, Israel, NATO members, and Syria. Kaspersky Lab said it does not believe itself to be the main target and that it had not shared its own findings about the attack with Russian authorities until the FSB announcement.
On 20 June 2024, after the US announced that it would prohibit Kaspersky from selling or distributing updates to its software to US customers, the company announced it would leave the US market. On September 25, the company abruptly replaced its software on US users' computers with UltraAV software developed by US cybersecurity firm Pango, angering some users.
Kaspersky Lab develops and markets antivirus, internet security, password management, endpoint security, and other cybersecurity products and services. It is the fourth or fifth largest endpoint security vendor and the third largest consumer IT security software company. It is the sixth largest overall IT security company. Its revenues are about 15 percent from Russian companies domestically, one-third from European organizations and one-fourth from US organizations. The software has about 400 million users in all.
Kaspersky's consumer software include the Antivirus, Internet Security and Total Security products. The Antivirus software includes malware protection, monitors the PC for suspicious program behavior, and warns users about potentially dangerous websites. The Internet Security software adds privacy features, parental controls, anti-phishing tools. Total Security adds parental controls, adult website filters, diagnostic tools, a Password Manager application, and other features. Kaspersky's software is available for Macs, PCs, Android, iOS, Windows Mobile, BlackBerry and Symbian.
For businesses, the company has developed Kaspersky Industrial CyberSecurity for OT environments, and Kaspersky Hybrid Cloud Security for container infrastructures. Detection and response solutions include Kaspersky Next XDR Expert, Kaspersky Next EDR Optimum, and Kaspersky SIEM for centralized security monitoring. The company markets the Kaspersky Endpoint Security for Business suite. It includes a centralized user interface and management application called the Kaspersky Security Center. The cybersecurity software itself is called the Kaspersky Security Network. The Kaspersky Administration KitSecurity Center manages configuration, installation and remote use. The business suite also has quarantine, reporting, and other features. Its software product for businesses with 25 staff or less is called Kaspersky Small Office Security (KSOS). Within the suite are products specifically for virtualization security, mobile security, and fraud protection among others. Kaspersky also develops a free tool that helps businesses gain access to Windows devices that are infected by ransomware.
The Kaspersky Anti-Virus engine also powers products or solutions by other security vendors, such as Check Point, Bluecoat, Juniper Networks, Microsoft Forefront, Netintelligence, Clearswift, FrontBridge, Netasq, Wedge Networks, and others. Altogether, more than 120 companies are licensing technology from Kaspersky Lab. Kaspersky Lab also has a number of partnerships with various technology companies.
Kaspersky's 2013 Endpoint Security for Windows product was the top-ranked enterprise antivirus software in a competitive test by Dennis Technology Labs, followed by Symantec Endpoint Protection. AV-Comparatives awarded Kaspersky "Product of the Year" for 2015, based on the number of high scores it received throughout the year on a wide range of tests. PC Magazine praised the software's features, but said it lacked policy management and deployment options. Kaspersky's parental controls software was reviewed by PC Magazine. The reviewer said it was "well-rounded, very affordable parental control and monitoring". It praised the software's content filtering, child profiles, social media monitoring and other features, but criticized that some features were only available on iOS or Android.
The anti-virus software testing group AV-Comparatives gave the Windows XP version of Kaspersky AV an "Advanced+" rating (its highest) in both its February 2008 on-demand detection test (with the fourth highest detection rate among 16 products tested). However, in the Retrospective/Proactive Test May 2008, Kaspersky received the "Standard" rating, detecting 21% of new malware with 1-month old signatures and receiving a substantial amount of false positives.
The firewall included in Kaspersky Internet Security 7.0 got a "Very Good" rating in Matousec's Firewall challenge, with a result of 85%. Kaspersky Anti-Virus 7.0 has achieved a 6.5 result out of 8 in the Anti Malware Labs rootkit detection test. It has also achieved a 31 out of 33 detection of polymorphic viruses and a 97% result in the self-protection test.
In 2007, Kaspersky Internet Security 7 received an award from the British magazine PC Pro and also won a place in its "A List".
On February 1, 2012, Kaspersky Internet Security earned "AV-TEST Award for Best Repair 2011" award in the field of home user products from AV-TEST Institute. On January 28, 2013, Kaspersky Endpoint Security earned "AV-TEST Award for Best Protection 2012" and "AV-TEST Award for Best Repair 2012" awards in the field of corporate products from AV-TEST Institute.
Later in 2013, Kaspersky earned the product of the year award from AV-Comparatives and the highest score among Enterprise solutions in a Dennis Technology Labs report.
Kaspersky has also received certification of its products through the OESIS OK Certification Program, which verifies that the applications are interoperable with third-party technology solutions like NAC and SSL VPN products from Cisco Systems, Juniper Networks, F5 Networks, and others.
Kaspersky products regularly participate in and achieve high results in independent tests by AV-Test, AV-Comparatives, and SE Labs. These organizations are members of the Anti-Malware Testing Standards Organization (AMTSO), which Microsoft has adopted as an “industry standard organization” for independent certification purposes.
Kaspersky Lab's Global Research and Analysis Team (GReAT) was established in 2008. It investigates cybersecurity threats and other work by malware operations. IT security companies are often evaluated by their ability to uncover previously unknown viruses and vulnerabilities. Kaspersky's reputation for investigating cyber-security threats has been influential in gaining sales and prestige. Beginning around 2010, Kaspersky exposed a series of government-sponsored cyber-espionage and sabotage efforts. These include Stuxnet, Duqu, Flame, Gauss, Regin and the Equation Group. According to Wired, "many of them [were] seemingly launched by the US and its UK and Israeli allies. Kaspersky is especially well-known for its work uncovering Stuxnet, Careto, and Flame."
Flame was an earlier variant of Stuxnet. Kaspersky never verified the source of the software, but it is suspected to have been developed by the National Security Agency (NSA) to transmit keystrokes, Skype calls and other data. Kaspersky created algorithms to find similar malware and found Gauss that July, which collected and transmitted data from devices infected by bluetooth or USB drives.
In February 2014, Kaspersky identified the malware Mask, which infected 380 organizations in 31 countries. Many organizations that were affected were in Morocco. Some of the files were in Spanish and the group is believed to be a state conducting espionage, but Kaspersky did not speculate on which country may have developed it.
In November 2014, Symantec and Kaspersky authored papers that contained the first disclosure of malicious software named Regin. According to Kaspersky, Regin is similar to QWERTY, a malware program discovered the next year. Regin was used to take remote control of a computer and is believed to have originated from the Five Eyes alliance. That same month Kaspersky reported on the Darkhotel attack, which targeted users of wireless networks at hotels in Asia. It asked users to update their software, and then download malware that gave up their passwords.
In 2015, Kaspersky identified a highly sophisticated threat actor that it called "The Equation Group". The group incorporated sophisticated spying software into the firmware of hard drives at banks, government agencies, nuclear researchers and military facilities, in countries that are frequent targets of US intelligence efforts. It is suspected to have been developed by the National Security Agency (NSA) and included many unique technical achievements to better avoid detection. That same day, Kaspersky announced the discovery of a hacker group it called Carbanak, which was targeting banks and moving millions of dollars into fake accounts. Carbanak was discovered when one bank asked Kaspersky to investigate suspicious behavior from its ATMs. A similar malware using some of the same techniques as Carbanak was discovered in 2016 and dubbed Carbanak 2.0.
In June 2015, Kaspersky reported that its own network had been infiltrated by government-sponsored malware. Evidence suggested the malware was created by the same developers as Duqu and Stuxnet, in order to get intelligence that would help them better avoid detection by Kaspersky in the future. Kaspersky called it Duqu 2.0. The malicious software resided in memory to avoid detection. The hack was believed to have been done by the same group that did Duqu in 2011. It used exploits in Microsoft installer files.
In June 2015, Kaspersky Lab and Citizen Lab both independently discovered software developed by Hacking Team and used by 60 governments around the world to covertly record data from the mobile phones of their citizens. The software gave police enforcement a "menu of features" to access emails, text messages, keystrokes, call history and other data. Kaspersky also identified 37,000 attacks against banking companies that used modifications of the malware called Asacub and took control of Android devices. Asacub targeted mostly banking customers in the US, Russia and Ukraine using an SMS message that baited users into installing a Trojan.
In 2016, Kaspersky uncovered the Poseidon Group, which would infiltrate corporations with malware using phishing emails, then get hired by the same company as a security firm to correct the problem. Once hired, Poseidon would install additional malware and backdoors. In June 2016 Kaspersky helped uncover a Russian hacking group, leading to 50 arrests.
In 2020, Kaspersky published research on the MATA Toolset Campaign, a sophisticated cyber-espionage framework targeting multiple operating systems, including Windows, macOS, and Linux. The malware, attributed to the Lazarus Group, was used for stealing databases, distributing ransomware, and installing backdoors on infected systems. MATA's capabilities allowed attackers to execute a wide range of malicious activities, including exfiltrating sensitive data from corporate networks and compromising financial systems. The campaign highlighted the increasing cross-platform threat posed by state-sponsored actors. In September 2022 and October 2023, new malware samples linked to the MATA cluster were uncovered.
In 2023, Kaspersky exposed NKAbuse, a sophisticated multiplatform malware written in the Go programming language. This malware leveraged blockchain technology for its peer-to-peer communication infrastructure, making it resilient to takedowns. NKAbuse functioned as a flooder and a backdoor, enabling attackers to launch distributed denial-of-service (DDoS) attacks and gain persistent access to compromised systems. The campaign illustrated the evolving use of blockchain in cybercrime and reinforced the need for enhanced detection methods.
In 2023, Kaspersky uncovered Triangulation, a sophisticated spyware campaign targeting iOS mobile devices. The malware exploited multiple zero-day vulnerabilities to gain full control of targeted devices. Triangulation was primarily distributed through malicious attachments in instant messaging apps. Once installed, it allowed attackers to access encrypted communications, GPS locations, and sensitive data. Kaspersky attributed the campaign to an advanced persistent threat (APT) group but refrained from naming a specific actor, though evidence suggested ties to state-sponsored espionage.
CloudSorcerer APT and its EastWind campaign were identified by Kaspersky in 2024.The malware leveraged public cloud infrastructure to perform large-scale data exfiltration and surveillance. The attackers used sophisticated phishing campaigns to infiltrate government and private sector organizations, especially targeting research institutions and critical infrastructure. CloudSorcerer employed novel encryption techniques to disguise data flows, complicating detection. Kaspersky linked the malware to a state-affiliated group but did not specify which country was behind the attack.
In 2024, Kaspersky exposed DuneQuixote, a stealthy malware campaign targeting intellectual property in the technology and energy sectors. The malware used custom-built exploits and employed fileless techniques, operating entirely in memory to evade detection by traditional security tools. DuneQuixote's attack vector included compromised software updates and supply chain vulnerabilities. Kaspersky attributed the operation to a well-funded APT group with global reach, though the precise origin remained unclear. The discovery highlighted the growing complexity of threats targeting high-value intellectual assets.
Since 2015, Kaspersky has faced allegations of close ties to the Russian government by various Western media outlets and governments. In October 2017, reports alleged that hackers working for the Russian government stole confidential data from the home computer of a US National Security Agency (NSA) contractor via Kaspersky antivirus software. Kaspersky denied the allegations, reporting that the software had detected Equation Group malware samples which it uploaded to its servers for analysis in its normal course of operation.
In February 2025, Australia banned Kaspersky software from government systems due to concerns over national security. The Department of Home Affairs issued a directive prohibiting the installation of Kaspersky products on government devices, citing risks of foreign interference, espionage, and sabotage. Government agencies must remove all existing Kaspersky software by April 1, 2025. This decision aligns Australia with other members of the Five Eyes intelligence pact, including the U.S., Canada, and the U.K., which have also restricted Kaspersky's use.
