The variety of units contaminated with data-stealing malware in 2023 was 9.8 million, a sevenfold improve over the identical determine for 2020, in keeping with new analysis from Kaspersky Digital Footprint Intelligence. Nevertheless, the researchers consider that the true determine could possibly be as excessive as 16 million, as credentials from units contaminated in 2023 is probably not leaked onto the darkish net till later this 12 months (Determine A).

Cybercriminals stole a mean of fifty.9 credentials per compromised system, and 443,000 web sites have had consumer data leaked up to now 5 years.
The information was obtained from log information that document the actions of “infostealers.” Infostealers are a kind of malware that covertly extracts knowledge from contaminated units with out encrypting it. These logfiles are “actively traded in underground markets” and monitored by Kaspersky as a part of its digital threat safety service.
Sergey Shcherbel, skilled at Kaspersky Digital Footprint Intelligence, stated in a press launch, “Leaked credentials carry a significant menace, enabling cybercriminals to execute numerous assaults equivalent to unauthorized entry for theft, social engineering or impersonation.”
Why is the variety of data-stealing malware instances rising?
Infostealers are extra accessible
In response to a report by IBM, there was a 266% improve in infostealing malware in 2023 over the earlier 12 months. It seems to be efficient, too, as incidences of criminals gaining entry through the use of legitimate login credentials went up by 71%.
The recognition of infostealers is broadly regarded to be linked to the rising worth of company knowledge and the malware’s rising accessibility. In separate analysis, Kaspersky Digital Footprint Intelligence discovered that 24% of malware offered as a service between 2015 and 2022 was infostealers, which permit newbie cybercriminals to make the most of infostealers developed by one other group and distributed by way of the darkish net.
Luke Stevenson, cyber safety product supervisor at managed service supplier Redcentric, informed TechRepublic in an electronic mail, “Stealer malware considerably lowers the entry barrier to would-be cyber criminals, making knowledge breaches simpler. Exfiltrated knowledge has quick worth regardless of the direct sufferer’s monetary sources and could be offered on shortly throughout the vary of illicit prison boards.
“The malware is comparatively straightforward to compile and deploy with supply codes accessible for these beginning out. Not like ransomware which has its personal enterprise ecosystem, these working infostealers usually have a lot decrease overhead prices.”
Aamil Karimi, menace intelligence chief at cybersecurity agency Optiv, informed TechRepublic in an electronic mail, “There was a notable rise in new stealer malware launched to the cybercriminal ecosystem starting in 2019, together with very fashionable strains like RedLine, Lumma and Raccoon. A few of these stealer malware variants have been utilized in ransomware operations which have proven elevated exercise over the previous couple of years. These variants are very cheap, they usually have confirmed to work, so there may be incentive for extra potential criminals to affix these malware-as-a-service operations and affiliate packages.”
Moreover, the proliferation of “devoted leak websites,” the place stolen credentials are posted, supplies extra targets for infostealers. The extra websites of this nature are energetic — and the quantity grew by 83%, in keeping with Group-IB’s Hello-Tech Crime Developments 2022/2023 report — the upper the danger that corporations could have their units compromised. Analysis from Group-IB revealed the variety of corporations that had their knowledge uploaded to leak websites in 2023 elevated by 74% over the earlier 12 months.
Provide chains have gotten extra complicated and susceptible
Another excuse that data-stealing malware instances are rising is because of the provide chain. Third-party distributors are sometimes given entry to inner knowledge or use linked methods and should present a neater entry level that results in confidential knowledge belonging to the goal group.
Dr. Stuart Madnick, an IT professor and cybersecurity researcher on the Massachusetts Institute of Know-how, wrote within the Harvard Enterprise Overview, “Most corporations have elevated the cyber safety of their ‘entrance doorways’ via measures equivalent to firewalls, stronger passwords, multi-factor identification, and such. So, attackers search different — and typically extra harmful — methods to get it. Usually, meaning coming in by way of distributors’ methods.
“Most corporations depend on distributors to help them, from doing air-con upkeep to offering software program, together with computerized updates to that software program. As a way to present these providers, these distributors want easy accessibility to your organization’s methods — I refer to those because the ‘facet doorways.’ However, these distributors are incessantly small corporations with restricted cybersecurity sources.
“Attackers exploit vulnerabilities in these vendor methods. As soon as they’ve some management over these vendor methods, they will use the facet door to get into the methods of their clients.”
Analysis from the Financial institution for Worldwide Settlements means that international provide chains have gotten longer and extra complicated, which will increase the variety of potential entry factors for attackers. A report from the Id Theft Useful resource Middle discovered that the variety of organizations impacted by provide chain assaults surged by greater than 2,600 share factors between 2018 and 2023.
Malware sorts are rising in quantity
The quantity of malware accessible to cybercriminals is rising exponentially, in keeping with Optiv’s senior malware analyst McKade Ivancic, facilitating extra data-stealing assaults. He informed TechRepublic in an electronic mail, “The extra that stealer-family malware is authored, the extra these households’ code bases shall be pilfered and re-written into comparable, but barely completely different, data-stealers.”
He added, “Safety groups, merchandise, signatures and the like can not develop exponentially like malware can. Till a extra everlasting answer is discovered, the ‘good guys’ shall be naturally outpaced on account of sheer numbers, compound development, ease of entry, lack of enforcement and assault floor growth by way of rising expertise and software program investments.”
WFH and BYOD fashions are extra commonplace
Karimi informed TechRepublic, “The rise within the work-from-home and bring-your-own-device fashions since 2020 additionally probably contributed to elevated threat to corporations whose workers’ units weren’t centrally or responsibly managed.”
Private units are inclined to lack the identical safety measures as company-provided units, creating a bigger assault floor for criminals seeking to deploy data-stealing malware. Microsoft’s Digital Protection Report 2023 said that as much as 90% of ransomware assaults in 2023 originated from unmanaged or bring-your-own units.

What sort of credentials do cybercriminals goal?
The credentials typically focused by attackers utilizing data-stealing malware are people who may result in helpful knowledge, cash or privileged entry. Such particulars could embody company logins for emails or inner methods, in addition to social media, on-line banking or cryptocurrency wallets, in keeping with the Kaspersky analysis.

One other research by the agency discovered that over half (53%) of units contaminated with data-stealing malware in 2023 have been company. This conclusion was drawn from the truth that the vast majority of contaminated units with Home windows 10 software program are particularly operating Home windows 10 Enterprise (Determine B).

How a lot knowledge could be extracted with data-stealing malware?
Every log file analyzed by Kaspersky Digital Footprint Intelligence on this research contained account credentials for a mean of 1.85 company net functions, together with emails, inner portals and buyer knowledge processing methods. Which means criminals are sometimes in a position to entry a number of accounts, each enterprise and private, after infecting a single system.
The log file knowledge additionally revealed {that a} fifth of workers would reopen the malware on their system greater than as soon as, giving the cybercriminals entry to their knowledge on a number of events with out the necessity for reinfection.
Shcherbel stated within the press launch, “This will point out a number of underlying points, together with inadequate worker consciousness, ineffective incident detection and response measures, a perception that altering the password is adequate if the account has been compromised and a reluctance to analyze the incident.”
What do cybercriminals do with the stolen knowledge?
In response to Kaspersky Digital Footprint Intelligence, menace actors will use the credentials stolen from malware-infected units for a lot of functions. These embody:
Perpetrating cyberattacks on different events.
Promoting them to others on the darkish net or shadow Telegram channels.
Leaking them totally free to sabotage a corporation or higher their very own repute.
Shcherbel stated within the press launch, “The dark-web worth of log information with login credentials varies relying on the information’s attraction and the best way it’s offered there.
“Credentials could also be offered via a subscription service with common uploads, a so-called ‘aggregator’ for particular requests, or by way of a ‘store’ promoting lately acquired login credentials solely to chose consumers. Costs sometimes start at $10 per log file in these outlets.
“This highlights how essential it’s each for people and firms – particularly these dealing with giant on-line consumer communities – to remain alert.”
How can companies shield themselves from data-stealing malware?
To protect towards data-stealing malware, researchers at Kaspersky Digital Footprint Intelligence really useful the next:
Monitor darkish net markets for compromised accounts related to the corporate.
Change the passwords of compromised accounts and monitor them for suspicious exercise.
Advise probably contaminated workers to run antivirus software program on all units and take away any malware.
Set up safety options on firm units that alert customers to risks like suspicious websites or phishing emails.
TechRepublic consulted different specialists for extra recommendation.
Encryption and entry controls
Matthew Corwin, managing director at cybersecurity agency Guidepost Options, informed TechRepublic in an electronic mail: “Encryption of information each at relaxation and in transit is vital for stopping data-stealing and publicity assaults, however for this to be efficient a complete defense-in-depth safety structure across the encrypted property can be required.”
Stevenson added that “securing accounts by way of password managers and multi-factor authentication” is a crucial primary step for safeguarding account credentials from unauthorized use.

Threat assessments
Corwin informed TechRepublic, “Periodic safety and threat assessments may help determine particular weaknesses in a corporation’s safety posture which could possibly be exploited by menace actors utilizing data-stealing malware.”
Training
Karimi informed TechRepublic, “Creating a extra proactive strategy to threat administration requires training and consciousness — each for the IT group and safety directors, in addition to customers generally.
“Safety consciousness is commonly touted as a default advice, however threat consciousness is just not. It’s extra complete than a single on-line safety consciousness coaching module… You will need to set up processes to determine and monitor probably the most related threats which are distinctive to your setting.”
He added that “drafting, updating and imposing enterprise use instances and consumer insurance policies for net exercise” can present extra safety assurance by guaranteeing all workers are dealing with their credentials safely.
