49 Corporate Email Phishers arrested in Operation Triangle

The Europen Union's Judicial Cooperation Unit, EUROJUST, along with Europol's European Cybercrime Center (EC3) and the Joint Cybercrime Action Taskforce (J-CAT) have announced one of their most successful cyber actions to date.   The case, known internally as Operation Triangle, involves three lead agencies - Italy's Postal and Telecommunications Police through its office in Perugia, Spain's Investigative Court no. 24 in Barcelona, and Poland.  (EUROJUST Press Release: "Eurojust and Europol in massive joint action against cybercriminals")

58 search warrants were executed in Spain, Poland, Italy, Belgium, Georgia, and the United Kingdom, resulting in 20 arrests in Italy, 18 arrests in Poland, 10 arrests in Spain, and 1 arrest in Belgium.  Most of those arrested were from Nigeria and Cameroon. 

By gaining control of the email accounts of well-placed individuals in corporations across Europe, the criminals were able to alter requests for payment to send the payments to themselves rather than the business bank accounts that were the intended destinations.  In a short period of time, more than 6 million euros were transferred to accounts controlled by the criminals.

In the United Kingdom, where the J-CAT task force is headquartered, recent government reports indicated that 81% of large businesses (>250 employees) and 60% of small businesses (less than 50 employees) experienced an information security breach in 2013.

Next week, many European governments will be represented in the Octopus Conference 2015: Cooperation Against Cybercrime. Through the work of Octopus and others, European agencies are gradually coming into agreement on how to address multi-jurisdictional cybercrime.  At last year's Octopus conference, delegates were encouraged to work together through 18 Cybercrime Scenarios.  Fascinating puzzles that we NEED agreement on if we are truly going to stand a chance against the multi-national criminals who steal from our citizens.

Phishing contro aziende: 62 arresti in Italia e all’estero, smantellata rete internazionale

Phishing Against Companies:  62 arrested in Italy and Abroad, International network dismantled: 
An operation that goes from Perugia to Turin and expands throughout Europe.  Here's how the scammers did it.

Via "LaStampa" journalist Carola Frediani and Google Translate -- 

It all started with a payment of 33 thousand euro. A routine, a transfer made ​​by a company of the Venetian food, which through its Spanish subsidiary had paid a supplier. Or rather, what he thought to be a provider, not suspecting that behind the request for a change of code Iban which paid the money was concealed an organization dedicated to computer fraud to the detriment of businesses and recycling. He had before hacked supplier and now he was impersonating online through email.
So that money, rather than to the real suppliers of the Veneto, end up on a postal account in Perugia made ​​out to a citizen of Cameroon. Which in turn has contacts with a criminal group based in Turin, specializes in money laundering and run by Nigerians, as revealed recently in an investigation of Europol and the Guardia di Finanza Piedmont.

 Operation Phishing 2.0

This episode started then the footage of another Italian international investigation, codenamed Phishing 2.0, which has once again at the center of the fraud against companies, and this morning has resulted in 62 arrest warrants in various countries, including 29 issued by prosecutors in Perugia.
An investigation then born and coordinated in Perugia, bounced on Turin had already been identified where a hub of illicit proceeds, and extended between Italy, Spain and Poland, with the support of Europol and Eurojust, the judicial cooperation unit of 'European Union.

The victims

Fifty (7 of which are Italian) companies all over the world were victims of digital fraud, 800 scam transfers were identified, 800 thousand euro taken away from businesses and recovered during the investigation, around 5 million euro estimate of the economic damage caused by the group in its business that dates back to 2012. The offenses: unauthorized access to computer systems, impersonation, aggravated fraud, and receiving stolen property.

How did it work

The mechanism of the scam started with a series of computer intrusions in the mailboxes of the companies targeted - characterized by having many foreign relations - through an advanced form of phishing, a technique that consists of sending email fake trying to trick the recipient, and then infect and / or [carpirgli] information. After obtaining the credentials of the emails of employees of a company, cybercriminals were monitoring the exchange of mail identifying commercial relationships, creditors and debtors; then they sent an email to the debtor to turn communicating a change of Iban [online payment destination address?]. Iban that actually corresponded to an account managed by a member of the organization.
 
To manage the assets of phishing was a network of Nigerians, Cameroonians and Senegalese, some of whom were residents in Italy. Once at the bank, also on many giro Italian, the money were taken quickly and redistributed abroad through various systems, including money transfer. "There was a division of roles," he told La Stampa Anna Lisa Lillini, assistant chief of the police post Umbrian added. "Who identified the victims took 50 percent of the amount; who was offering the bill received 30%; and the mediator that the hacker got in touch and took the 20%. " The amount stolen went from 800 up to 250 thousand euro. "In one case we have intercepted one wire of 300 thousand euro from America to  Turin," explains Lillini.

Between Umbria and Piedmont

Turin made ​​from recycling center, and here the investigation Perugia converges with what we previously reported from Turin, [LaStampa's article "Nigerian Drops: Women and Companies Cheated Online"] . In that system, the money stolen from the companies were sent to other parties, with dozens of credit transfers and of people involved, up to a stage where cash was taken piecemeal. A branched system, which were scattered in many streams ([ribattezzatto] precisely Nigerian Drops by investigators) and that has been traced through some specific analysis tools used by Europol. "In one case, one person has taken 150 thousand euro in eight hours making dozens of drops in different branches," says La Stampa Captain David Giangiorgi of the Financial Police of Turin. "The fraud was perpetrated by persons residing in Nigeria. The money was sent in the form of assets purchased with the proceeds of the scam and then shipped to the African country. "

A growing phenomenon

This kind of scams are increasingly common. "Just this week, carrying out a survey of defense on behalf of an Italian company that had lost many thousands of euro through a similar system, we were able to triangulate who had sent the phishing emails, and these seem to come just from Lagos (Nigeria) ", explains Paolo Dal Checco, the Turin studio of computer forensics, Digital Forensics Bureau (Di. Fo. B) that has long followed precisely such cases.
 
The interesting aspect is that the story in question fraudsters had been in touch with the company through Skype, as well as email. And through the program of VoIP (and with some tracking systems of the email), computer forensic experts have identified the IP address of the interlocutors. "By now using increasingly sophisticated techniques," says Dal Checco. "In some cases they go even to call pretending to be a creditor of the company contacted."


UPDATE #2 -- The News from Spain

The Spanish National Police have also released information about this case, in their press release of June 10, 2015.   As with the Italian article above, click the Spanish headline below for the original article.  For the convenience of English-speaking readers, we share a Google-translate-assisted version below:

Credentials obtained in this way by organized criminal groups hurts many Internet clients, while generating billions of euros of profits for organized crime groups.

Phishing Success Rates and Google Phish

Last week a group of Google employees led by Elie Bursztein joined UCSD researchers Andreas Pitsillidis and Stefan Savage in presenting the findings of a study on phishing to the ACM Internet Measurement Conference in Vancouver, British Columbia. Their paper, Handcrafted Fraud and Extortion: Manual Account Hijacking in the Wild (12 page PDF) was picked up broadly in the press, and as usual, wildly misinterpreted.

At least 110 articles referring to the study were found in a simple Google News search with headlines ranging from the somewhat accurate:

  • Manual Phishing Gmail Attacks Found To Be Very Effective - Top Tech News, Nov 9, 2014
  • Google Study Finds Email Scams Are More Effective Than You'd Expect - Huffington Post, Nov 7, 2014
  • Old-time phishing scams are working just fine, Google finds - Naked Security, Nov 11, 2014
to the extreme bending of the facts for headline value such as these:
  • Phishing attacks on email accounts are successful 45 percent of the time - Firstpost, Nov 10, 2014
  • Phishing scams work 45% of the times: Google study - Times of India, Nov 10, 2014
  • Have You Been Scammed? Phishing Emails Successful 45% of the Time - Crave Online, Nov 11, 2014
  • A scary number of you are still falling for phishing scams, says Google - Nov 10, 2014

What did Google and UCSD Actual Say about Phishing?

First, the 45% quote. For the 100 Google/Gmail phishing sites that the researchers studied, they found that depending on the structure of the page, as few as 3% of the visitors filled out the phishing form and submitted their data. Overall 13% of the visitors to the webforms shared their personal data with the phishers, while in the most extreme example, 45% of the visitors to the phishing web page completed the form and submitted their personal data.

There were several interesting findings in the study. A few that I found interesting included:

  • 35% of phishing sites target victims' email
  • 21% of phishing sites target banking credentials
  • A growing number of phishing sites are targeting App Stores and Social networking credentials
  • Account takeovers are primarily Fast and Foreign:
    • 20% of compromised Google accounts were logged into within 30 minutes
    • The top countries of origin for hijackers were China, Ivory Coast, Malaysia, Nigeria, and South Africa
  • The easiest way to have your account restored is to have registered an SMS telephone number for out of band contact.

Manual Hijacking

The focus of this study was the process of Manually Hijacking accounts belonging to Google users. Because of that focus, it is not clear how broadly the observed behaviors can or should be projected onto other types of phishing. At Malcovery Security we observe 600 to 800 newly created phishing sites per day. This study focused primarily on Gmail/Google phish from January 2014, and for part of the study focused specifically on 100 Gmail phishing websites.

Google provided some statistics on how widely the problem of manual hijacking has been seen in the past. Over calendar 2012-2013, Google's security teams found that approximately 9 manual hijacking cases per day per million active users occurred. With over 500 million subscribers, Google is dealing with thousands of such account hijacks per day.

With Google participating in the research, researchers were able to determine that when an account is taken over, the criminals login to the account and search the email history and address books to determine how best to monetize the account. It seems that every week someone will make the comment in my presence "Yes, I have malware on my computer, but the worst that might happen is they get my email password!" But think about what is possible with that? How would you reset your password at your Bank? Amazon.com? eBay? On most of those sites, clicking "I Forgot My Password" results in an email being sent with a "Reset My Password" link! If the criminal finds an email from your bank in your email history, they now know exactly which bank to visit to click the "I Forgot My Password!" The email account is the key to the entire balance of your account!

The researchers also found that the scam we first wrote about in 2009 in the post Traveler Scams: Email Phishers Newest Scam is still quite prevalent. In this scam, because the criminal has access to your recent sent emails and address book, they are able to contact your friends and family with news of a tragedy while traveling where they desperately need money wired overseas to help them through the crisis. I've met many individuals who have wired money to their friends before realizing it was a scam! They often have stories of how they KNEW the email was truly from their friend, because when they asked questions, their friend replied with details only the friend would know. Often these details made use of prior "private" conversations in the phishing victim's email sent items box!

Popular Email Phish from Malcovery's ThreatHQ System

In the past seven days, Malcovery Security confirmed 416 distinct phishing URLs related to Google and their properties. These URLs were hosted on 207 distinct domain names on 174 different IP addresses. By country, the United States is the most prominent host of phishing sites, not just for Google, but for nearly every brand that does business in the USA. Of those 174 IP addresses, 90 are in the United States.

Although this phishing site is PRIMARILY imitating DropBox, it still steals Gmail and other email credentials:
The domain hosting this phish was "t-online.de".
