Safety researchers at SafeBreach came upon one way to gather tens of millions of stolen consumer credentials thru Google’s malware research platform, VirusTotal with out compromising any organizations.
Consistent with the researchers, an attacker best wishes a €600 ($679) license to get admission to VirusTotal’s top class gear and APIs equivalent to VirusTotal Graph and retrohunt to get admission to stolen consumer credentials.
Named “VirusTotal hacking,” the infection-free method is very similar to “Google hacking,” one way utilized by criminals to spot prone programs, put in internet shells, and IoT gadgets.
To check their concept, SafeBreach researchers controlled to gather a million credentials from the platform inside of a couple of days.
Attackers can accumulate limitless stolen consumer credentials on VirusTotal with little effort
The researchers known as it the very best cybercrime as a result of an attacker the use of this technique can collect a nearly limitless collection of delicate consumer information with little effort. Moreover, the sufferers can’t simply give protection to themselves from this kind of job as a result of they have got no visibility into the exfiltrated recordsdata.
3rd-parties equivalent to safety researchers, webhosting corporations housing the hacker’s command-and-control (C2) servers, and cybercriminals unknowingly add stolen consumer credentials to VirusTotal.
Tomer Bar, Director of Safety Analysis at SafeBreach, additionally advised that hackers add sufferers’ information on VirusTotal whilst selling the sale of stolen consumer credentials on underground boards. Consistent with Bar, gaining access to those stolen consumer credentials on VirusTotal was once a stroll within the park.
“It’s somewhat a simple methodology, which doesn’t require robust figuring out in malware,” Bar stated. “All you wish to have is to make a choice one of the vital not unusual information stealers and examine it on-line.”
Attackers best want to know quite a lot of gear utilized by cybercriminals to thieve knowledge and the recordsdata they use to add stolen consumer credentials on C2 servers. Moreover, getting access to quite a lot of underground hacking boards like DrDark and Snatch_Cloud is useful when looking on VirusTotal.
Researchers demonstrated how stolen consumer credentials are got
The researchers effectively demonstrated tips on how to get admission to a vast collection of information from VirusTotal. They looked for information leaked by the use of RedLine Stealer, Azorult, Racoon Stealer, and Hawkeye.
RedLine Stealer is a subscription-based malware in a position to harvesting stored credentials, bank cards, and auto-complete information from browsers. The malware additionally takes stock of the host laptop recording the software knowledge and configuration, together with geographical location, put in instrument, and different knowledge.
The researchers won a minimum of 800 effects for RedLine variants detected as ‘engines:MSIL.Trojan-Stealer.Redline.B.’ They looked for the ‘DomainDetects.txt’ document used to add information, and located effects tagged ‘content material:DomainDetects.txt tag:zip’.
The use of VirusTotal gear, they came upon that the zipped document contained every other RAR document (TG @BitPapaFREELOGS 08.2021 500 PIECES.rar) with 22,715 passwords from 500 sufferers.
BitPapa is the title of a Russian cryptocurrency marketplace and in addition a telegram channel. The researchers advised that the recordsdata had been intentionally uploaded to VirusTotal.
In addition they discovered every other 200 MB document with the filename containing “bitpapa.” The document contained 46,952 passwords from 1,000 sufferers.
Different discoveries come with information from 34 sufferers, together with cryptocurrency knowledge; and 800 passwords, together with 30 from executive URLs, with 40 sufferers from the Ministry of Well being.
The researchers repeated the method with Azorult and looked for the exfiltration document named ‘YandexBrowser_Default.txt’. The quest returned 162 effects containing CV recordsdata, credentials from social media websites Fb and Snapchat, Apple, and Australian executive accounts.
They discovered the “Новая папка” document containing 136,000 passwords from 1,000 sufferers, together with credentials from 1,300 executive websites from 48 international locations. The knowledge incorporated credentials from 30 tax government just like the IRS from america, UK, India, and different international locations.
In a similar fashion, the researchers recovered a minimum of 96,000 stolen consumer credentials thru Raccoon Stealer, together with partly encrypted recordsdata and a minimum of 200 sufferers from HawkEye.
Moreover, the researchers came upon recordsdata presented on DrDark and Snatch_Cloud underground boards thru VirusTotal seek.
“Those actions are performed at the common internet,” they wrote. “There’s no want for darkish internet get admission to—those people don’t seem to be hiding themselves.”
The researchers submitted their analysis findings, recordsdata containing private information, and the implicated API keys to Google. The beneficial periodically looking and doing away with delicate information from VirusTotal and banning API tokens used to add stolen consumer credentials.
Nasser Fattah, North The united states Steerage Committee Chair at Shared Tests, noticed that, “Cybercriminals generally enrich leaked and stolen credentials (the typical consumer ID and password) with date-of-birth, telephone numbers, safety questions, together with solutions, and different related knowledge that may be simply used for id robbery and account takeover – each with the intent to devote fraud. Word many of those leaked/stolen credentials stem from third-party breaches and depend on folks reusing the similar password to authenticate to more than one websites. Why hassle with brute power assaults and cracking passwords when lively, legitimate credentials may also be purchased in so much.”
