Cybercrime is available in many various flavors, most of it being financially-oriented. Phishers, scammers and malware operators are essentially the most seen ones, but there are another profiles within the cybercrime economic system who play an vital function and are but very discreet: Traffers.
A brand new report from Sekoia sheds mild on traffers actions.
What’s a traffer?
Traffers — from the Russian phrase “Траффер,” additionally known as “employee” — are cybercriminals liable for redirecting Web customers community site visitors to malicious content material that they function, this content material being malware more often than not.

Traffers are usually organized as groups and compromise web sites to be able to hook the site visitors and produce the guests to malicious content material. They could additionally construct web sites serving the identical goal. As uncovered by Sekoia researchers who’ve monitored Russian talking cybercrime boards, the traffer ecosystem is constructed of each extremely expert profiles and new ones, making it a superb entry level for freshmen in cybercrime.
The “lolz Guru” underground discussion board particularly reveals fixed new creation of traffers groups, each month of 2022 seeing between 5 and 22 new traffers groups (Determine A).
As soon as created, a traffer staff may evolve and reorganize, merge with different groups or restart from scratch, which makes it troublesome to guage the longevity of traffer groups. One administrator of such a staff has indicated it price him $3,000 to create a traffer staff of 600 folks earlier than promoting it. A traffer staff dubbed “Moon Crew” was priced at $2,300 in Could 2022.
The everyday group for such a staff is fairly easy: One or a number of staff directors lead traffers but additionally deal with the malware licenses and the evaluation and promoting of the logs collected by the traffers (Determine B).
What are traffer staff strategies?
The largest exercise from traffers consists of redirecting Web customers to malware, 90% of which consists of knowledge stealers. The data stolen by the malware might be legitimate credentials for on-line companies, mailboxes, cryptocurrencies wallets or bank card data. All of these are referred to as logs.
The staff directors do promote these logs to different cybercriminals who exploit this knowledge for monetary achieve.
The directors are additionally liable for dealing with the malware they want, shopping for licenses to the malware builders and spreading it to the staff.
The directors additionally present their groups members with a equipment containing totally different sources:
- Continually up to date malware information (additionally referred to as “malware builds”) prepared to be used.
- A crypter service or instrument, essential to encrypt or obfuscate the malware information.
- A guide and pointers for traffers.
- A search engine marketing service to enhance the visibility and variety of connections to their infrastructure.
- A Telegram channel to speak simply between staff members.
- Telegram bots for automating duties, akin to sharing new malware information and creating statistics.
- A devoted log evaluation service to make sure the logs bought by the directors are legitimate.
As soon as recruited, traffers are capable of get the malware information and distribute through redirections from compromised web sites. They’re paid primarily based on the standard and amount of knowledge they gather from the malware they deploy.
Traffers are sometimes challenged into competitions organized by the directors. The winners get additional money and entry an expert model of the membership. This entry permits them to make use of a second malware household, get higher companies and bonuses.
Every traffer makes use of their very own supply chain so long as it complies with the staff necessities.
In response to Sekoia, frequent supply strategies embrace web sites masquerading as blogs or software program set up pages and delivering password protected archive information to be able to keep away from detection. Skilled traffers appear to have an excellent information of promoting platforms and handle to extend the promotion of their web sites through these companies. The draw back of this sort of supply technique for the attackers is that it usually hits many victims and is due to this fact extra shortly detected than different supply technique.
The 911 an infection chain
Nearly all of traffers groups monitored by Sekoia are literally exploiting a way referred to as “911” in underground boards.
It consists of utilizing stolen YouTube accounts to distribute hyperlinks to malware managed by the traffers. The traffer makes use of the account to add a video engaging the customer to obtain a file, disable Home windows Defender and execute it. Generally, the video is about cracking software program. The video explains the way to proceed and supplies hyperlinks to instruments for putting in cracked software program, generate a license key or cheat at totally different video video games. As soon as executed, these information infect the pc with malware.
The malware is mostly saved on reliable file serving companies akin to Mega, Mediafire, OneDrive, Discord or GitHub. Generally it’s a password protected archive file, which comprises the stealer malware (Determine C).
What malware is utilized by traffers?
Essentially the most used data stealing malware utilized by traffers, as noticed by Sekoia, are Redline, Meta, Raccoon, Vidar and Personal Stealer.
The Redline malware is taken into account the simplest stealer, because it is ready to entry credentials from net browsers, cryptocurrency wallets, native system knowledge and several other functions.
Redline additionally permits the directors to simply monitor traffer exercise by associating a singular botnet identify within the samples distributed by a traffer. Stolen knowledge coming from using Redline are bought on a number of marketplaces. Meta is a brand new malware and is marketed as an up to date model of Redline, turning into the malware of selection for some traffer groups.
The right way to shield your self from traffers
This menace is very associated to malware and will goal people as a lot as corporations. Deploy safety options and antivirus options on all endpoints and servers of the corporate. Working techniques and all software program must also be stored updated and patched to forestall them from being contaminated by the exploitation of a standard vulnerability.
Customers needs to be skilled to detect phishing threats and to keep away from at any case utilizing cracked software program or instruments. Multi-factor authentication needs to be used each time potential. A traffer checking for the validity of stolen credentials may simply drop it whether it is unusable with no second authentication channel.
