Top hackers on Russian-speaking cybercriminal underground are making various deals to gain maximum profits, either by selling access to compromised accounts or auctioning stolen data from previous attacks. A threat actor dubbed Sheriff was seen making a similar offer for several active accounts on a cybercrime forum.
Sheriff targets eToro
‘Sheriff’, a threat actor who is known for its specialization in targeting banks, financial institutions, and government agencies, was found selling active accounts of eToro users.
Earlier this month, ‘Sheriff’ advertised an auction for 62,000 accounts of eToro, a social trading platform.
The offer included login credentials, contact numbers, postal addresses, and balances for a starting price of $1,500.
Recent attacks by Sheriff
Sheriff, which uses brute-forcing and credential-stealing malware and Citrix remote desktop protocol (RDP) exploits, has been involved in several cyberattacks in the past few months.
In June 2020, Sheriff held Citrix RDP access to a European construction company focused on oil projects and advertised access to 3,200 cPanel accounts.
In May 2020, they gained admin access to an e-commerce organization's WordPress plugin and information on about 815,000 orders.
Connections with REvil’s syndicate
Recently, cybersecurity firm AdvIntel found a connection between REvil operators and several other threat actors including Sheriff, all being part of a network intrusion-focused criminal syndicate.
REvil gang has recently deepened its cooperation with Sheriff. It is believed that REvil used a new alias ‘unknown,’ which is similar to the group’s “UNKN” alias, to interact with the Sheriff.
Besides Sheriff, the REvil gang is also in close contact with several other threat groups, namely Kerberos and Energydrinkkk, all apparently working together as a crime syndicate.
