Some of the infamous suppliers of abuse-friendly “bulletproof” hosting for cybercriminals has began routing its operations by networks run by the Russian antivirus and safety agency Kaspersky Lab, KrebsOnSecurity has realized.
Safety consultants say the Russia-based service supplier Prospero OOO (the triple O is the Russian model of “LLC”) has lengthy been a persistent supply of malicious software program, botnet controllers, and a torrent of phishing websites. Final yr, the French safety agency Intrinsec detailed Prospero’s connections to bulletproof companies marketed on Russian cybercrime boards below the names Securehost and BEARHOST.

Bulletproof hosts are so named after they earn or domesticate a popularity for ignoring authorized calls for and abuse complaints. And BEARHOST has been cultivating its popularity since not less than 2019.
“In the event you want a server for a botnet, for malware, brute, scan, phishing, fakes and another duties, please contact us,” BEARHOST’s advert on one discussion board advises. “We fully ignore all abuses with out exception, together with SPAMHAUS and different organizations.”
Intrinsec discovered Prospero has courted a few of Russia’s nastiest cybercrime teams, internet hosting management servers for a number of ransomware gangs over the previous two years. Intrinsec mentioned its evaluation confirmed Prospero incessantly hosts malware operations akin to SocGholish and GootLoader, that are unfold primarily through faux browser updates on hacked web sites and infrequently lay the groundwork for extra critical cyber intrusions — together with ransomware.

BEARHOST prides itself on the flexibility to evade blocking by Spamhaus, a corporation that many Web service suppliers around the globe depend on to assist establish and block sources of malware and spam. Earlier this week, Spamhaus mentioned it noticed that Prospero was instantly connecting to the Web by routing by networks operated by Kaspersky Lab in Moscow.
Replace, March 1, 9:43 a.m. ET: In a written assertion, Kaspersky mentioned it’s conscious of the general public declare in regards to the firm allegedly offering companies to a “bulletproof” hosting supplier. Right here is their full assertion:
“Kaspersky denies these claims as the corporate doesn’t work and has by no means labored with the service supplier in query. The routing by networks operated by Kaspersky doesn’t by default imply provision of the corporate’s companies, as Kaspersky’s computerized system (AS) path may seem as a technical prefix within the community of telecom suppliers the corporate works with and gives its DDoS companies.”
“Kaspersky pays nice consideration to conducting enterprise ethically and guaranteeing that its options are used for his or her unique function of offering cybersecurity safety. The corporate is presently investigating the scenario to tell the corporate whose community may have served as a transit for a “bulletproof” hosting supplier in order that the previous takes the mandatory measures.”
Kaspersky started promoting antivirus and safety software program in america in 2005, and the corporate’s malware researchers have earned accolades from the safety neighborhood for a lot of vital discoveries over time. However in September 2017, the Division of Homeland Safety (DHS) barred U.S. federal companies from utilizing Kaspersky software program, mandating its elimination inside 90 days.
Cybersecurity reporter Kim Zetter notes that DHS didn’t cite any particular justification for its ban in 2017, however media reviews quoting nameless authorities officers referenced two incidents. Zetter wrote:
In keeping with one story, an NSA contractor creating offensive hacking instruments for the spy company had Kaspersky software program put in on his residence pc the place he was creating the instruments, and the software program detected the supply code as malicious code and extracted it from his pc, as antivirus software program is designed to do. A second story claimed that Israeli spies caught Russian authorities hackers utilizing Kaspersky software program to go looking buyer programs for information containing U.S. secrets and techniques.
Kaspersky denied that anybody used its software program to seek for secret info on buyer machines and mentioned that the instruments on the NSA employee’s machine have been detected in the identical manner that every one antivirus software program detects information it deems suspicious after which quarantines or extracts them for evaluation. As soon as Kaspersky found that the code its antivirus software program detected on the NSA employee’s machine weren’t malicious packages however supply code in improvement by the U.S. authorities for its hacking operations, CEO Eugene Kaspersky says he ordered employees to delete the code.
Final yr, the U.S. Commerce Division banned the sale of Kaspersky software in the U.S. efficient July 20, 2024. U.S. officers argued the ban was wanted as a result of Russian legislation requires home corporations to cooperate in all official investigations, and thus the Russian authorities may drive Kaspersky to secretly collect intelligence on its behalf.
Phishing knowledge gathered final yr by the Interisle Consulting Group ranked internet hosting networks by their measurement and focus of spambot hosts, and found Prospero had the next spam rating than another supplier by far.

It stays unclear why Kaspersky is offering transit to Prospero. Doug Madory, director of Web evaluation at Kentik, mentioned routing information present the connection between Prospero and Kaspersky began at first of December 2024.
Madory mentioned Kaspersky’s community seems to be hosting several financial institutions, together with Russia’s largest — Alfa-Financial institution. Kaspersky sells companies to assist defend clients from distributed denial-of-service (DDoS) assaults, and Madory mentioned it may very well be that Prospero is solely buying that safety from Kaspersky.
But when that’s the case, it doesn’t make the scenario any higher, mentioned Zach Edwards, a senior risk researcher on the safety agency Silent Push.
“In some methods, offering DDoS safety to a well known bulletproof internet hosting supplier could also be even worse than simply permitting them to hook up with the remainder of the Web over your infrastructure,” Edwards mentioned.
