Fauxpersky Keylogger masqueraded as Kaspersky Antivirus and spreads via USB drives

Posted: 30 Mar 2018 10:08 PM PDT

 

Security researchers at Cybereason recently discovered a credential-stealing malware dubbed Fauxpersky, that is masquerading as Kaspersky Antivirus and spreading via infected USB drives.

Fauxpersky was written in AutoIT or AutoHotKey, which respectively are a freeware BASIC-like scripting language designed for automating the Windows GUI and general scripting and a free keyboard macro program to send keystrokes to other applications.

The analysis of infected systems revealed the existence of four dropped files, attackers named them as Windows system files: Explorers.exe, Spoolsvc.exe, Svhost.exe, and Taskhosts.exe.

After initial execution, the Fauxpersky keylogger gathers the listed drives on the machine and starts replicating itself to them.

“This AHK keylogger utilizes a fairly straightforward method of self propagation to spread. After the initial execution, the keylogger gathers the listed drives on the machine and begins to replicate itself to them. Let's examine the process:” reads the analysis.

“This allows the keylogger to spread from a host machine to any connected external drives. If the keylogger is propagating to an external drive, it will rename the drive to match it’s naming scheme.”

The malware renames the external drives to match its naming scheme, the new name is composed of the following convention:

original name:size:”Secured by Kaspersky Internet Security 2017"

it also creates an autorun.inf file to point to a batch script.

One of the dropper files, Explorers.exe, includes a function called CheckRPath() designed creates the files if they are not already present on the drive.

The keylogger created the files with attributes System and Hidden and also creates the necessary directories, with parameters of Read-Only, System, and Hidden.

“When starting the process of creating the component files (HideRFiles()) we begin by starting a loop. This loop allows the keylogger to iterate over the various output files it needs to write to disk in a structured way.” continues the analysis. “We can see that the link (a .lnk shourtcut file), text, and batch files will all be created for each disk to start. Then the value passed to the function gets incremented to allow the created directory to be moved as a whole once the files have been placed there. “

The files are stored in the source directory named Kaspersky Internet Security 2017 when it is copied to the new destination. The folder included a Kaspersky image named Logo.png and a text file containing instructions for users to disable their antivirus if execution fails. The instructions also include a list of security tools "incompatible with Kaspersky Internet Security 2017" (Kaspersky Internet Security included).

Fauxpersky monitors the currently active window using the AHK functions WinGetActiveTitle() and input(), Keystrokes are appended to the file Log.txt that is stored in %APPDATA%\Kaspersky Internet Security 2017.

The malware gains persistence by changing the working directory of the malware to %APPDATA% and creating the Kaspersky Internet Security 2017 folder. It checks that all the necessary files are created in %APPDATA% and copies them there if they aren't.

The files Spoolsvc.exe is used to change the values of registry keys to prevent the system from displaying hidden files and to hide system files, then it verifies if explorers.exe is running and launches it if not.

Fauxpersky keylogger

Fauxpersky exfiltrates the keylogged data using a Google form.

"Exfiltrating data to a Google form is a very simple and clever way to overcome a lot of the "logistics" involved in data exfiltration. Using this technique means there's no need to maintain an anonymized command and control server plus data transmissions to docs.google.com is encrypted and doesn't look suspicious in various traffic monitoring solutions." Cybereason concluded.

Systems at a Power Company in India infected by a ransomware

Posted: 30 Mar 2018 11:27 AM PDT

A ransomware infected systems at the Uttar Haryana Bijli Vitran Nigam power company in India, crooks demanded 10 million Rupees to get the data back.

The Uttar Haryana Bijli Vitran Nigam power company in India was hacked last week, attackers breached into its computer systems and stole the billing data of their customers.

The hackers demanded 10 million Rupees to get the data back (roughly $152,000 USD).

cerber ransomware

The intrusion occurred on March 21 night, a ransomware infected the systems and the day after the employees discovered that their data were encrypted.

“In a first of the kind of a case in the country, the hackers have stolen the billing data of the Uttar Haryana Bijli Vitran Nigam (UHBVN), one of the two power discoms of Haryana and have demanded Rs One crore in form of bitcoins from the state government to retrieve the data.” states the New Indian Express.

“Sources said that UHBVN which is monitoring electricity billings of nine districts of the state came under cyber attack at 12.17 AM after midnight on March 21 and thus the billing data of thousands of consumers had been hacked as the IT wing of the nigam was target.”

The Haryana Police launched an investigation trying to trace the IP address from where the attack was originated.

The officials at the company are uploading the billing data from the log books, anyway the incident could have a significant impact on the billing activities due to the difficulties to estimate current consumption in absence of data. The good news is that the billing of about 4,000 consumers has already started functioning normally.

“The Nigam had already taken steps much before to phase out the said system and to be replaced by latest, robust and technologically advanced system on cloud services which would be operational by the end of May 2018. The billing of about 4,000 consumers has already started functioning normally” added an official of the Nigam.

Ensuring best website security through SSL Certificate updates.

Posted: 30 Mar 2018 05:26 AM PDT

What are the advantages for adopting an SSL Certificates and why is it important to discover and analyze SSL Certificates online?

Secure Socket Layer (SSL) has gained weight with the increasing concern of security for all sensitive data online. In fact, it is the only reliable source for secure business and data handling. The entire information that travels between the computers all over the world is kept fully safe from potential dangers with the help of SSL. The business portals need high-level security to keep their own and their customers' data away from malicious intentions.

Advantages of SSL Certificates

The safety of the data traveling across the World Wide Web is encrypted by SSL. Only the intended users like sender and receiver can understand it. Any third person involved in data handling cannot pick any of its information. Credit card details, usernames, passwords etc. stay secured identity thieves and hackers.  Here are some vital benefits of using SSL:

The secure HTTPS/SSL version promises the business websites to operate securely and exchange the data between its partners and customers without any fear of loss, hacking or theft.

Meeting the Standards of Payment Card Industry with SSL

Online monetary dealings take place through credit cards and these cards carry highly sensitive and important information. The Credit Card Industry ensures the full protection of this valuable information through a setup standard. The companies can meet this standard of security by using SSL certificates only.  A website passes some audits that declare that it is using SSL and complying with the Payment Card Industry standards.

SSL Certificates for Guarding against Scams

SSL certificates are actually procedures that encode a message between two parties: sender and receiver. No third party can snoop in. This cryptographic technology secures the link between a remote browser and a web server. This encrypted message is a hard nut for phishing proxies and hackers. They cannot make any use of the message in case they intercept it which is impossible for them. The coded message shows just like a string of random hash.

Importance of Discovering SSL Certificates

Most of the e-commerce websites operate through the main domain and several subdomains. Each of these is involved in a heavy online business. IT professionals manage these portals through a number of intricate jobs. This leaves the website vulnerable to threats, thus SSL certificates need to be renewed.

Analyzing and discovering SSL certificates at a website is highly important at this stage.  There are many companies that provide discovery tools. There is Comodo Certificate Manager. This finds the location, expiry date, and other information on an SSL certificate. Another service is DigiCert which discovers SSL certificates in use, finds neglected or expired certificates and identifies vulnerabilities.

The latest variant of the Panda Banker Trojan target Japan

Posted: 29 Mar 2018 11:46 PM PDT

Security researchers at Arbor Networks have discovered a threat actor targeting financial institutions in Japan using the Panda Banker banking malware (aka Zeus Panda, PandaBot).

Panda Banker was first spotted 2016 by Fox-IT, it borrows code from the Zeus banking Trojan.

In November 2017, threat actors behind the Zeus Panda banking Trojan leveraged black Search Engine Optimization (SEO) to propose malicious links in the search results. Crooks were focused on financial-related keyword queries.

The main feature of the Panda Banker is the stealing of credentials and account numbers, it is able to steal money from victims by implementing “man in the browser" attack.

The Panda Banker is sold as a kit on underground forums, the variant used in the last attacks against Japan if the version 2.6.6 that implements the same features as the previous releases.

“A threat actor using the well-known banking malware Panda Banker (a.k.a Zeus Panda, PandaBot) has started targeting financial institutions in Japan.” reads the analysis published by Arbor Networks.

“Based on our data and analysis this is the first time that we have seen Panda Banker injects targeting Japanese organizations.”

An interesting aspect of this campaign targeting Japan is that none of the indicators of compromise (IOC) was associated with previous attacks.

The threat actor delivered the banking trojan through malvertising, victims were redirected to the domains hosting the RIG-v exploit kit.

Crooks leveraged on multiple domains and C&C servers, but at the time of the analysis, only one of them was active. The unique active domain hillaryzell[.]xyz was registered to a Petrov Vadim and the associated email address was yalapinziw@mail.ru.

The campaign that hit Japan also targeted websites based in the United States, search engines, and social media sites, an email site, a video search engine, an online shopping site, and an adult content hub.

“The threat actor named this campaign "ank".” continues the analysis. “At the time of research, the C2 server returned 27 webinjects that can be broken down into the following categories:

  • 17 Japanese banking web sites mostly focusing on credit cards
  • 1 US based web email site
  • 1 US based video search engine
  • 4 US based search engines
  • 1 US based online shopping site
  • 2 US based social media sites
  • 1 US based adult content hub”

The webinjects employed in this campaign leverage the Full Info Grabber automated transfer system (ATS) to capture user credentials and account information.
