'BadRabbit' ransomware, Fake 'Invoice', 'Scan Data', 'Order acknowledgement' SPAM
FYI...
'BadRabbit' ransomware attacks...
> https://www.bleepingcomputer.com/new...astern-europe/
Oct 24, 2017 - "A new ransomware strain named 'Bad Rabbit' is wreaking havoc in many Eastern European countries, affecting both government agencies and private businesses alike. At the time of writing, the ransomware has hit countries such as Russia, Ukraine, Bulgaria, and Turkey. The speed with which Bad Rabbit spread is similar to the WannaCry and NotPetya outbreaks... ESET and Proofpoint researchers say Bad Rabbit has initially spread via -fake- Flash update packages, but the ransomware also appears to come with tools that help it move laterally inside a network, which may explain why it spread so quickly across several organizations in such a small time..."

Fake 'Invoice' SPAM - using 'DDE exploit'

24 Oct 2017 - "Another Locky ransomware campaign using the DDE exploit[1]...

... the word doc contains embedded -links- that use the DDE exploit to contact a remote server & get a base64 encoded string which decodes to a set of instructions to contact a list-of-urls in turn, until one responds...
Asking somebody to 'update links' seems innocent enough and many recipients will click 'yes':
Update fields warning message from DDE exploit word doc:

... many of the intermediate stages and files never get stored or kept on the victim’s computer, in fact the final Locky binary is deleted as soon as it has been run, so there are few forensic artefacts for investigation. Brad Duncan has done a Blog post at ISC explaining all this in detail[2] with examples from the earlier run.

Banking Trojan targets Google Search, 'Coin Miner' Malware - hits Google Play
FYI...
Banking Trojan targets Google Search Results (SEO)
- http://blog.talosintelligence.com/20...-campaign.html
Nov 2, 2017 - "It has become common for users to use Google to find information that they do not know. In a quick Google search you can find practically anything you need to know. Links returned by a Google search, however, are not guaranteed to be safe. In this situation, the threat actors decided to take advantage of this behavior by using Search Engine Optimization (SEO) to make their malicious links more prevalent in the search results, enabling them to target users with the Zeus-Panda-banking-Trojan. By poisoning the search results for specific banking related keywords, the attackers were able to effectively target specific users in a novel fashion. By targeting primarily financial-related keyword searches and ensuring that their -malicious- results are displayed, the attacker can attempt to maximize the conversion rate of their infections as they can be confident that infected users will be regularly using various financial platforms and thus will enable the attacker to quickly obtain credentials, banking and credit card information, etc. The overall configuration and operation of the infrastructure used to distribute this malware was interesting as it did not rely on distribution methods that Talos regularly sees being used for the distribution of malware. This is another example of how attackers regularly refine and change their techniques and illustrates why ongoing consumption of threat intelligence is essential for ensuring that organizations remain protected against new threats over time... The initial vector used to initiate this infection process does not appear to be email based. In this particular campaign, the attacker(s) targeted specific sets of search keywords that are likely to be queried by potential targets using search engines such as Google. By leveraging compromised web servers, the attacker was able to ensure that their malicious results would be ranked highly within search engines, thus increasing the likelihood that they would be clicked on by potential victims...
Having a sound, layered, defense-in-depth strategy in place will help ensure that organizations can respond to the constantly changing threat landscape. Users, however, must also remain vigilant and think twice before clicking-a-link, opening-an-attachment or even blindly trusting the results of a Google search..."

'Coin Miner' Malware - hits Google Play
- http://blog.trendmicro.com/trendlabs...s-google-play/
Oct 30, 2017 - "... Recently, we found that apps with -malicious- cryptocurrency mining-capabilities on Google Play. These apps used dynamic JavaScript loading and native code injection to avoid detection. We detect these apps as ANDROIDOS_JSMINER and ANDROIDOS_CPUMINER. This is not the first time we’ve found these types of apps on app stores. Several years ago, we found -malicious- apps on the Google-Play-store detected as ANDROIDOS_KAGECOIN, a malware family with hidden-cryptocurrency-mining capabilities:
> https://www.gdatasoftware.com/blog/2...es-to-the-moon
However, we’re now seeing apps used for this purpose, which we detect as ANDROIDOS_JSMINER and ANDROIDOS_CPUMINER. This is not the first time we’ve found these types of apps on app stores. Several years ago, we found malicious apps on the Google Play store detected as ANDROIDOS_KAGECOIN, a malware family with hidden cryptocurrency mining capabilities.*
* https://blog.gdatasoftware.com/blog/...-the-moon.html
... We’ve previously seen tech support scams** -and- compromised websites used to deliver the Coinhive JavaScript cryptocurrency miner to users. However, we’re now seeing apps used for this purpose, which we detect as ANDROIDOS_JSMINER.
** http://blog.trendmicro.com/trendlabs...-monero-miner/
We found two apps; one supposedly helps users pray the rosary, while the other provides discounts of various kinds:
> https://blog.trendmicro.com/trendlab...d-mining-1.png
...
> https://blog.trendmicro.com/trendlab...d-mining-2.png
Both of these samples do the same thing once they are started: they will load the JavaScript library code from Coinhive and start mining with the attacker’s own site key... This JavaScript code runs within the app’s webview, but this is -not- visible to the user because the webview is set to run in -invisible- mode by default... Another family of malicious apps takes -legitimate-versions- of apps and adds mining libraries, which are then repackaged and distributed. We detect these as ANDROIDOS_CPUMINER. One version of this malware is in Google Play and disguised as a wallpaper application:
> https://blog.trendmicro.com/trendlab...d-mining-5.png
These threats highlight how even mobile devices can be used for cryptocurrency mining activities, even if, in practice, the effort results in an insignificant amount of profit. Users should take note of -any- performance degradation on their devices after installing an app. We have reached out to Google, and the apps mentioned in this post are no longer on Google Play..."

Fake 'invoice' SPAM - delivers Locky

7 Nov 2017 - "... an email with a subject of 'Invoice #231910390' (random numbers) pretending to come from XXDocumentSend at your own email address or company domain... Once again the word doc contains an embedded OLE object that when clicked on opens a PowerShell script which contacts a remote server & get a text string which contains a set of instructions to contact a list of urls in turn, until one responds, to download the main Locky ransomware or Trickbot binary...

... over the last couple of weeks or so the downloaders from the Necurs botnet used system fingerprinting to decide which malware to give to any victim. Certain countries and IP ranges got Locky, others got Trickbot banking trojan. I am pretty sure that these Word embedded OLE downloaders and the downloaders will also be using the same techniques:

In previous phishing and malware scams by this criminal gang they used a range of domain numbers between 1 and 600 over several days, so there could be a lot more to come.
