In their August Online Fraud Report RSA reports on the activity of online fraudsters, a summary is below.
A five-year retrospect on Fraud as a Service (FaaS) reveals that the types of services sold today have changed very little; the more noticeable changes came in the shape of scalability, service relevancy, higher availability, better deals, customer support and buyer guarantees.
Underground criminals buy and sell goods and services around the clock. The fact that these markets operate online eliminates borders and physical distance, allowing people from different parts of the world to wheel-and-deal and to partner-up in the orchestration of fraud cash-out cycles without ever meeting or speaking on the phone.
What do they sell?
For phishing – scam pages, complex phishing kits and custom kit plugins, spamming services, email databases, junk traffic, SEO poisoning, email cracking tools, spam software, and SMS spoofers, to name a few. After the attacker gathers the spoils, fraudsters can opt to buy the already-harvested databases of phishing attacks or purchase unitary ‘logins’ in an online shop selling compromised data.
For botmasters – Trojan-related facilitators exploit kits, malware spam, botnets, Trojan kits, HTML injections, customized malicious code, encryption services, bulletproof hosting, pay-per-installs/affiliate infection schemes, plugins, set-up and tech support.
Hardly ever does one fraudster take on the complete fraud cycle; rather, fraudsters opt to partner with more experienced criminals or offer up their own expertise (such as performing in-store pick up of goods obtained with stolen credit card data). Much like real-world crime, each actor ‘gets his hands dirty’ to different extents. Bottom line – the fraudulent transaction is turned into cash in different ways and the profits are shared among those involved.
Those who don’t have any trustworthy connections in the world of fraud find and use transfer and cash-out services. Money mule, cash-out services and Item-drop mules have become ever so popular, that some vendors have already automated them for those who attempt the bulk of transactions each day bot herders and ‘carders’.
Almost all busy criminals today connect with a mule repository operator and have their fraudulent transactions go through the vendor’s mules, receiving a cut of each successful transaction as per a mutual agreement. Some cases of mule-repositories are part of the fraud cycle of one gang.
Recent underground fraud services:-
Hire a “Man-in-the-Middle”
One of the more interesting recent FaaS offers was found in an underground forum, posted by a Russian-speaking member offering his infrastructure for very temporary hire, alongside his own services as a man-in-the-middle facilitator. The botmaster had a few perks for customers who wish to attempt Trojan attacks without having to set up anything whatsoever:
- Rent the infrastructure – gain access to infected bots
- Pay to target and harvest – send over a trigger and a Trojan injection and those will be pushed to existing infected bots on the botnet (through a Trojan configuration file update)
- Pay to attack – the botmaster will facilitate fraudulent transaction attempts using his Trojan’s remote administration access to bots
Buy a Botnet
The vendor behind this offer was also working in collaboration with other cybercriminals, each offering a related service a bot herder would need for the set up and operation of a botnet.
Automated Customer Support
In the recent past, Trojan developers only offered support via live chat using instant messaging services (Jabber, ICQ). A developer could only support a limited number of chats until the burden of supporting his customers became too great and support deteriorated or stopped altogether.
Trojan developers did understand the substantial need for customer/technical support and took pains to find new ways to preserve their customer base. To get an idea about just how ‘real’ customer support has become, take a quick look at this SpyEye vendor’s page. Notice the headers on the page; much like legitimate software companies – they direct users to an FAQ page, an “About SpyEye” section, and provide a detailed web form that can be sent directly to the vendor’s alleged support team, automating the process.
Many of today’s fraud service vendors put strong emphasis on supporting their buyers, offering guarantees and assistance, from the exchange of faulty or invalid cards and access credentials, all the way to providing set-up, tutorials, and tech support to those who have to operate on going online fraud operations (botnets, CC shops, exploits etc.).
One cannot mention excellent cybercrime customer support today without “Citadel” coming to mind. The team developing the Citadel Trojan has long established itself as the new go-to crimeware vendor, well on their way to inheriting the Zeus Trojan market share they built upon. The most unique feature this team offers to botmasters using Citadel is a clever CRM model that supports, tickets, listens and advises members on how to set up and operate their Trojans. The CRM is not optional! All botmasters must join it and pay a fixed monthly fee for their membership.
A better cybercrime marketplace, much like organized crime in the physical world, increasingly affects the world’s economy by the sheer amounts of money it taxes it every year. The worst part about this dark economy is its faceless, covert nature and thus the hardship in quantifying and understanding the extent of its damage.
Stronger crime economies are a burden on the legitimate economy in hard costs but do not stop there. This large scale clandestine operation also affects crime statistics and touches real-life aspects of law enforcement and the legal system. Due to cybercrime’s global, scattered nature, fighting it often requires internationally coordinated investigations and arrests, further taxing the resources of each nation touched by digital crimes.
Phishing Attacks per Month
Phishing attacks in July increased 14% from June, marking yet another high of 59,406 attacks in a single month. In examining an overall spike in attacks, the bulk of last month’s increase can be attributed to highly targeted phishing campaigns launched against a series of financial institutions in Europe.
Number of Brands Attacked
In July, a total of 242 brands were targeted with phishing attacks, marking a 7% drop from June. As compared to July 2011, last month’s list of phishing targets demonstrates a 25% year-over-year drop in the number of targeted brands.
US Bank Types Attacked
There was very little change in how the U.S. banking sector was targeted by phishing in July. Nationwide banks still continue to be targeted by about three out of every four phishing attacks. This reflects the tendency of cybercriminals to attack larger financial institutions.
Top Countries by Attack Volume
For the fifth consecutive month, the UK was targeted by the highest volume of phishing attacks, followed by the U.S. and Canada. The UK endured 70% of worldwide attacks, its highest portion ever.
Top Countries by Attacked Brands
Although the UK was targeted by 70% of phishing volume in July, the U.S. continues to be the country with the greatest number of targeted brands. Brands in the U.K., Brazil, India, and Australia collectively were targeted by 27% of attacks in July.
Top Hosting Countries
The U.S. hosted 79% of worldwide phishing attacks last month, its highest portion to date according to the RSA Anti-Fraud Command Center. Canada, the UK and Germany accounted for hosting an additional 10% of attacks.
