“For your safety” – Beware of fake ING-DiBa emails

“For your safety” – Beware of fake ING-DiBa emails

Cybercriminals are currently trying to obtain sensitive data from ING-DiBa customers with dubious fake emails. The fake email claims that a problem has occurred during a routine security check of the online banking system. It advises that customers should immediately log on to an external website to avoid troubles with their bank.

However, in reality, this is a phishing attack that tries to collect personal information. In the following blog article, you will learn in detail how to protect yourself from fake emails or phishing attacks.

The fake email from our example

Fake E-Mail

A German ING-DIBA fake email (click for zoom)

The adjacent picture shows the detailed structure of the fake email – allegedly sent by ING-DiBa – in an iPhone mailbox. In fact, the email is part of a mass phishing attack and the message was sent fraudulently to a variety of email recipients.

For example, the subject line states “For Your Safety (Reference Number: xyz)”, and the presumable arbitrary order of the combination was set to “kx5qrvnzx3h” in this case. Before we blackened the personal information for reasons of data protection, we noticed that both the recipient’s address and the sender’s address had the same information. This was already a first indication of a fake email.

This scam is not uncommon amongst perpetrators when it comes to gathering information about their randomly selected victims via phishing. Those affected are especially inclined to follow the attached link if the phishing or fake email is opened on a mobile device, as it is in this case. This is particularly true if they are actual customers of the bank mentioned in the email.

In everyday life, too, recipients of phishing emails are also quick to follow the link when receiving such an email. The attacker offers the targeted person appropriate options in case a recipient does not have an account with ING-DiBa. In our example, the recipient has the opportunity to follow a flashy red button and allegedly communicate that he is not a customer of ING-DiBa. The destination of the link, however, is a phishing website, which is intended to tap user data in a big way from the mostly unsuspecting victims. The fake security notification of ING-DiBa is not an isolated case.

6 tips to detect phishing or fake emails

With the following tips, you will be able to detect phishing or fake emails to protect yourself from being affected by such attacks.

Feature No. 1: The salutation

It is striking that either a standard phrase is used to address the target person, or the salutation is completely missing. Very rarely recipients of phishing emails are addressed with their whole name. This is due to the fact that fake emails are not isolated cases, but often automated emails which are sent out millions of times. Individual addresses are rather the exception. In our example there was no address at all.

Feature No. 2: Content of the email

A phishing mail is contextually designed to hide the true intentions towards the recipient at least until he first clicks on one of the attached links. These following baits are very popular with cyber crooks:

  • Fake emails in the form of alleged PayPal security notifications
  • Phishing emails which seem to come from banks or other institutions
  • Fake email notifications that seem to come from Amazon or Ebay
  • Fake security issues in social media accounts that need to be resolved promptly

This shows that cybercriminals are very creative when it comes to fooling their victims.

Feature No. 3: The call to action

Once the attacker has created and sent out his fake email, he urges the recipient to act. In this specific case, the targeted person is initially led to an external page by clicking on a link. This page usually resembles closely the login area of a bank, an online retailer or any other company that offers certain Internet services.

Once the victim has entered his details into the according form fields and pressed the confirmation button, the cybercriminal is in possession of the login details. Now he can make orders in online shops under false names or get access to sensitive account or company data. The phishing attack has been successful.

Feature No. 4: The time shortage

An effective means often used by attackers is the limitation of time. This is an attempt to put the victim under stress and distract it. In our example, this is stated as follows: “Please log into your account as soon as possible to avoid any delay in your banking activities.”

Fear-spreading phrases in the subject line, such as “Your account has been suspended” or “An amount has been debited from your account” are also quite popular and common. These sentences cause some recipients to panic, so they follow the attached link without much thought.

Feature No. 5: Questionable buttons and links

In order to successfully carry out the process of phishing, a related link in text or button form is part of the standard repertoire of any phishing or fake email. This is also the case in our example.

Therefore, when it comes to questionable security queries that have a link, we recommend that you do not access these links from your email program. Instead, you should always directly log in to your user accounts via a browser or via the official website of the provider. This applies to online services of any kind.

Feature No. 6: This is how reputable companies and institutes work

As far as the detection of phishing emails or fake emails is concerned, it should always be remembered that reputable companies or institutes would never ask you to disclose personal information via email.

For this reason, various banks regularly point to the problem of fake emails or the so-called phishing mails. One bank states for example:

“Volksbank Raiffeisenbank or BVR will never ask bank customers for personal information such as PIN or account number via email. Neither will we insert a link to online banking in emails or ask bank customers to make test or remittance transfers. These practices are always indicators of attempted fraud.” (Source: Volksbank Raiffeisenbank)

Therefore, you can delete such an email immediately. This is ultimately the simplest way to counter a phishing attack.

Dangerous Amazon phishing emails cause trouble

Dangerous Amazon phishing emails cause trouble

Reputable and hardly suspicious – that’s how phishing emails, which have been circulating for several months and which allegedly come from Amazon, reach the mailboxes of many users. The reason for this is that those emails do not appear to be a cunning fraud but quite the opposite. They are so good in copying the design of a real Amazon email that they are hardly indistinguishable for end users. In addition, the cybercriminals use a personalized form of address in these phishing emails, which adds weight to the credibility of the email.

Example of such an Amazon phishing email

Example of such an Amazon phishing email (Click to enlarge image).

A phishing email personalized in this way is referred to as a “spear phishing attack”. These targeted attacks aim specifically at a single person or group of people. The behavior and personal data of target persons are spotted in advance in order to personalize the spear-phishing email the best possible way. Those fraud emails can only be identified through the sender address with which they were sent. These can, for example, be as follows:

More detailed information about possible sender addresses, the structure of phishing emails and content can be found here.

What do the attackers want to achieve?

 

Referring in the email to the Federal Data Protection Act, the victims are requested to verify their data. By clicking on a link, they are redirected to a fake website that is almost indistinguishable from the real Amazon site. On closer inspection, only the URL used does not match that of Amazon.

On the fake sites, the people concerned should then disclose data of themselves. Otherwise the hackers threaten to block access to the account, as shown in the example above. This is, of course, a hollow statement. Anyone who responds to this request, however, transmits his data directly to the fraudsters. The cybercriminals use the obtained data to make purchases at the expense of the person concerned or to misuse them for other criminal activities.

Does Hornetsecurity Advanced Threat Protection detect fake emails?

 

Hornetsecurity Advanced Threat Protection is able to detect the new Amazon phishing emails as well as other targeted attacks. Safety mechanisms including Fraud Attempt Analysis, Identity Spooning Recognition and Intention Recognition can filter out threats of this kind. A loss of sensitive data can thus be prevented and Amazon phishing emails do not even get into the mailboxes of a company or employees.

Disguised .NET Spyware Camolog is Stealing Access Data

Disguised .NET Spyware Camolog is Stealing Access Data

When it comes to new types of malware, there is always the question of what their objectives are. At the moment we are monitoring a new .NET spyware that has not yet been reported. It distinguishes itself by using persistent anti-analysis techniques implemented by utilizing the Confuser packer. Apart from that, the spyware does not put a lot of effort into disguising itself during runtime, thus revealing its intentions. This malware collects login details from many different programs and uses a keylogger to gather information.

 

This .NET spyware that we named Camolog is spreading due to an ongoing phishing campaign and it uses a keylogger to collect login details from mail clients, browsers, FTP and instant messenger clients. After these campaigns collect information, the access data gathered is usually sold by cybercriminals or used for later attacks.

 

In the individual emails of a large wave of spam emails, the subject headings (see screenshot) and attachments are slightly different. Most of the time, the attachments that deliver the malware are between 400KB and 1.3MB in size. In the following screenshot, you can see one of these phishing e-mails with the contact information crossed out, because in many cases, these are the information stolen from real people.

 

Example of a phishing mail that delivers malware.

Example of a phishing mail that delivers malware

 

The phishing email fools the recipients into believing that they are going to receive a price quote or an offer of some kind and this motivates them to open the attachment. However, it contains a RAR archive named “Sample Product 9076_pdf.rar”. The archive hides the executable .NET file “SampleProduct9076_pdf.exe” which serves as a dropper for the spyware and is secured by a version of the publicly available cover-up tool Confuser.

 

When opening the malware in the .NET decompiler dotPeek, the usage of Confuser becomes apparent. The project name “dimineata” is noticeable and can be used to identify the malware and is displayed in the screenshot below.

 

The .NET Decompiler dotPeek lets you analyze the Confuser.

The .NET Decompiler dotPeek lets you analyze the Confuser.

 

On the other hand, the application of both anti-decompiler and anti-debugger techniques makes it harder to analyze the malware. The analysis tool IDA Pro will crash when loading the binary file, specific .NET decompilers do not function properly and debuggers used in dynamic analyses fail, which means that manual analyses will rarely provide information. It’s likely that this is also one of the reasons why there is an absence of this spyware being publicly reported so far.

 

Bypassing security measures

 

The only way to obtain an overview of this malware’s behavior is to run it in a safe and controlled environment. In doing so, you can observe that the malware runs as a process named “chrome.exe” with the description “Accu-Chek 360˚ diabetes management software”. This process starts another sub-process with the same name. After a few moments, the original binary file generates a copy of itself as AppData\Local\Temp\iaq\iaq.exe, starts its sub-process and subsequently deletes itself.

 

At the time the sub-process is loaded, its binary data must be fully extracted and decrypted in the memory. The transfer takes place in the form of a byte array to the AppDomain.Load() function. This function is not affected by the anti-analysis methods of the cover-up tool because it belongs to the .NET framework. Unlike the malware functions, it can be easily analyzed. Thus, with a debugger such as dnSpy it is possible to set a breakpoint on this function and dump the binary file of the malware that is loaded by the dropper. But, let’s have a closer look into the malware itself.

Analysis of spyware.

 

The binary file of the dropped spyware is only masked by randomly renaming the functions and variables, not by additional anti-analysis methods. Therefore, it is possible to generate readable source code with a .NET decompiler again and thus reveal the behavior of the malware.

 

What information is collected?

 

The spyware collects numerous information: Next to the FTP Client SmartFTP’s connection data, which are saved in the favorites, but also passwords from the client WS_FTP, recently used connections from FileZilla, connections of saved sessions from WinSCP and the connection data from FTPWare.

 

Additionally, the account data saved in the Instant Messenger Pidgin and the passwords from the video chat tool Paltalk are read out. Camolog also diligently collects account data from the Outlook and Thunderbird mail clients as well as the login details from the YandexBrowser, ChromePlus and Chromium browsers. The spyware can also record all kind of data and password input with a keylogger.

 

The Spyware nests itself within the system by creating registry keys for Windows Autorun (see list of indicators). The malware is pretty good at identifying itself in the system through these registry keys and the running process “chrome.exe”.
