Ransomware Alert


Wipe Out Targeted Attacks


Criminals who organise targeted attacks based on blended threats emails use social engineering techniques to craft email messages that appear to be from a trusted sender but actually contain a link to a website hosting malicious code. They also use Microsoft office documents with embedded code, but the Radius BlockMail removes these. They will then use a variety of tools for greater access to information and systems. Blended Threats Module provides a powerful solution to targeted attacks and blended threats. Using real-time behavioural analysis and content inspection, the Blended Threats Module blocks any site serving suspicious or malicious code. Because the service doesn’t rely on signatures, it is never out of date when it comes to catching and neutralizing new exploits. Note that this is an additional add on to the BlockMail service.

The Blended Threats Module provides uncompromising security with no management overheads. Running as a cloud-based service means that protection is extended to any recipient who is forwarded a link that has been rewritten by BlockMail. The Blended Threats Module analyses millions of URLs daily, providing protection against targeted attacks and blended threats and feeding into Radius and Partners’ Labs research. Rather than relying on reputation or signature-based protection, it separates a webpage into its individual components (HTML, Java, Flash, ActiveX, etc.) putting each through their own dedicated analytical engines. Any obfuscated or hidden information is decoded and also subjected to rigorous analysis. Then additional deep code analysis determines a behavioural profile that reveals any potential malicious combination of the separate functions. This identifies and mitigates both unknown and dynamic threats. When a website is determined to be hosting malicious code, the Blended Threats Module will inform the user that access has been denied. As the URL has already been rewritten by BlockMail, this protection will be afforded to anybody who is subsequently forwarded the message, including users trying to access the compromised website via a mobile device or over webmail.

How does it work?

1. BlockMail receives the email for scanning and decides that a URL in the message body needs to be analysed. It rewrites the URL, pre-pending it with a unique customer reference and a link to the Blended Threats Module.

2. When a user clicks on the link, the request is directed through the Blended Threats Module for analysis.

3. The Blended Threats Module analyses Web content associated with the link, subjecting it to numerous checks for behaviour and intent.

4. If the webpage is free from malicious code, it is served to the user. If not, then the user receives a block page indicating that he or she has been protected from a targeted attack.


Multi-Layered Anti-Malware Engine Featuring BlockMail Dynamic and Real-Time Code Analysis

Both targeted and opportunistic attacks use advanced techniques to evade detection, exploit vulnerabilities and compromise computers. Real-time code analysis identifies the behaviour and intent of code being served by a webpage. It does not rely on signatures to ensure protection against both known and previously unseen attacks, which account for 60% of the modern malware missed by anti-virus, firewall, IPS/IDS and reputation-based solutions. Preventing machines from being compromised in the first place removes the costs associated with being the victim of any successful malware attack, such as desktop re-imaging, loss of data, damage to reputation or even fines.

Rewrites URL’s

With a rewritten URL, the link is scanned by the Blended Threats Module whenever a user clicks on the link, even if that email has been subsequently forwarded. This ensures that the target website is scanned at the time of access so there is no window of opportunity for an attack to take place.

Scans Websites on Access

During a staged targeted attack, the malicious code on a webpage may only become active after a certain period of time or for short spells during a day. This ability to hide, combined with the way active malicious code may change, means that it is essential to scan a website each and every time it is accessed from an untrusted link and the dynamic nature of the webpages.

Block Page Informs Users of a Threat

Notifying users of a potential threat not only stops them from visiting a website hosting malicious code, but it also acts as a reminder about safe computing habits, encouraging them to adopt a more cautious approach when browsing the Internet.

New Anti-Phishing protection Feature

We continue to improve our Blended Threats Module all the time and it now utilizes phishing intelligence from industry leading sources such as Trustwave’s SpiderLabs to help protect against phishing attacks.


General Advice on how organisations can protect themselves from Cyber Crime


1. Back up your systems
The biggest thing that will defeat ransomware is having a regularly updated backup. If you ask security experts their best advice on how to keep sensitive information secure from cyber-criminals, most of them will tell you that a back-up solution is the best option. If your system is infected and you lose your documents, you can restore your system to an earlier date and your files will be recovered.

2. Build Immunity
‘Standard’ anti-virus is not 100% effective, multiple layers of security are necessary to provide effective protection against cyber criminals. Patching is an important aspect of a good defensive strategy as this fixes vulnerabilities and improves network security.

3. Develop a Suitable Company Culture
One of the key features of these types of attacks is not technology. It is people. Ordinary users and how they behave when presented with well-crafted emails designed to fool them into doing something they otherwise would not do. Awareness and prevention is key to the fight against cyber criminals. Cyber security calls for a collective effort from everyone who has access to a computer or data bearing device. Security training programmes inform employees of the dangers and capabilities of cyber attackers and contingency plans should be drawn up accordingly to cope with the results of a worst case scenario.

4. Be One Step Ahead
Know your attack response before attacks happen. Regular audits and monitoring programmes can uncover vulnerabilities within your network. Know where attackers are most likely to attack and prepare for this eventuality. Train your people to be vigilant. Check, check and check again.
