Latest Version of "i-FILTER®" Updated with New Feature to Guard Against More Prevalent Falsified Websites and Boost New Security Genre of Whitelist Usage
Also Works Against Harmful "Emotet" Malware Attacks and Attacks Aimed at Company's Cloud E-mail

Information security solution provider Digital Arts Inc. (headquartered in Chiyoda-ku, Tokyo, Japan; CEO: Toshio Dogu; hereinafter referred to as "Digital Arts"; Code 2326) will release version 10.40 of its web security product "i-FILTER" on March 12, 2020. The new version has strengthened measures to counteract targeted attack e-mails at the network entrance by adding a new function to block transmission of IDs and passwords (credentials) to falsified websites.

Recently increasing targeted attacks using falsified websites as entry points

With the Tokyo Olympics scheduled for this year (now postponed), cyber-attacks are on the rise in Japan, and the resulting damage is forecast to be severe.
Among these, attacks targeting specific companies and organizations are continually increasing, making measures to prevent information leaks an urgent priority no matter the size, scale or type of industry. In the "Top 10 Security Threats of 2020" 1 released by the Information-technology Promotion Agency (hereinafter referred to as IPA), the top threat to information security at companies and organizations has been "Information theft via targeted attacks" for five years in a row since 2016.

In this situation, our company's "i-FILTER" Version 10 makes use of a whitelist to block access to potentially harmful unknown URLs that aim to exploit informational assets, and also uses a download filter function to block downloads of malware. This combination offers a strong line of defense against targeted attacks.

However, nowadays there are many cases where an attacker steals ID and password authentication information (credentials) by leading his targets to access files attached to e-mails and falsified websites linked from URLs, or where another causes a malware infection that infiltrates the company's network to exploit information. It is known that many of the "Emotet" 2 malware cases that have been circulating since late last year have used the same tricks. These falsified websites not only have an appearance difficult to distinguish from legitimate websites, but also the same URLs as the legitimate counterparts, posing a difficult challenge for security products.

Offering more robust security measures against attacks targeting credentials through falsified websites

To defend against this new technique, Digital Arts will offer "i-FILTER" Version 10.40 with a new feature to guard against falsified websites. These websites function as entry points for targeted attack e-mails. Version 10.40 makes use of Digital Arts' proprietary technology to ensure that users' IDs and passwords are not sent to the falsified web sites that users have a difficult time distinguishing, even if the users input these credentials. In this way, it prevents attackers from invading the network, making it possible to block the leakage of informational assets from the entrance. Also, if users attempt to download malware this is blocked thanks to the "download filter function" featured in previous versions with its settings now more aligned with real-world use.

Support for increased security while working from home due to COVID-19

With the recent increase in working from home due to the outbreak of COVID-19, more devices are set to be taken home by workers. Following from this, an increasing amount of informational assets are forecast to be transferred to cloud services through VDI and secure browsers. Falsified sites make use of these cloud service login pages, and cases can be seen where phishing scams target and attempt to leak companies' informational assets through these falsified pages.

"i-FILTER" Version 10.40 has new features that block unknown attacks and use a whitelist designed to guard against the falsified sites, which are increasingly more of a threat. These features add to a more robust security product and a safer work environment.

  1. 1 The IPA selects candidates from information security cases that emerged in 2019 and were thought to have had a major effect on society that year. These are selected by 140 members, including researchers in the information security field and those in charge at the actual companies, who hold a meeting to deliberate, vote on and rank the top 10 threats.
  2. 2 Emotet" is malware that was first observed in 2014, and has evolved many times. Digital Arts confirmed a case of infection in September of 2019 in which it was downloaded from a falsified website. In this case it used clever tricks to disguise itself, such as using the receiver's name, e-mail address and body text of previously transmitted e-mails. Since late last year the amount of damage has been increasing.

Web security product "i-FILTER" Version 10 guards against unknown threats

This is a web security product to safeguard against both external attacks including targeted attacks, and information leaks from internal sources.

"i-FILTER" Version 10.40 new features and feature improvements

The following features and improvements have been included to guard against the recently often seen trick of falsified websites purporting to be legitimate websites.

New features to block sending of IDs, passwords, etc. to falsified websites, "Credential Protection"

Digital Arts proprietary technology works so that for falsified websites that are normally difficult to distinguish, blocking attempts by users to send IDs or passwords to the site, thereby shutting down the entrance to fully prevent entry to the network.
For URLs that cannot be confirmed as being safe, even with an outward appearance that resembles a legitimate website and with the same URL, transmission is detected and blocked.

"Download Filter" set as default to block the download of high-risk files by detecting cleverly disguised filename extensions

The "Download Filter" feature on older versions of "i-FILTER" has had its default settings aligned more with real-world use, so as to not interfere with general work, only blocking files that have file extensions with high risk of malware infection, thereby protecting users from the latest threats.

For reference
Threat from falsified sites recently on the rise

53,894 attempts (10,358 attempts in December alone) at accessing falsified sites were observed in all of 2019 among customers who currently use Digital Arts' web security product "i-FILTER" Version 10.
