Emotet attacks— a spike to start the year...

The Emotet malware is a very destructive banking Trojan that was first identified in 2014. Over the years it has evolved with new capabilities and functionalities, prompting cybersecurity agencies like the Australian Cyber Security Centre and US-CERT to issue advisories. Emotet malware generally spreads via malicious documents that drop a modular Trojan bot, which is used to download and install additional remote access tools. We wrote a blog post in January 2019 about how the malware had changed tactics, leading to a spike in the number of Emotet malware attacks. In the last week, we have observed a spike in the number of Emotet malware transactions across our customer base. US-CERT has also issued a fresh advisory regarding the recent spate of attacks.

IE and FIREFOX-Patching nightmare begins in 2020...

Posted by Vinay Pidathala on Jan 27, 2020

Not all vulnerabilities are created equal. It’s true. In a perfect world, organizations should be able to patch every vulnerability on every client immediately. But we don’t live in a perfect world. Some vulnerabilities pose a much greater risk to the organization than others and should be prioritized.

Gartner Report on Remote Browser Isolation: Menlo Security’s Continued Validation

Posted by Mehul Patel on Jan 7, 2020

In October 2018, Gartner released a report on remote browser isolation. It ruffled feathers a bit throughout the cybersecurity industry by suggesting that enterprises can no longer assume that their traditional detect-and-respond security strategy was enough to stop all web-based malware attacks. Analyst Neil MacDonald argued that enterprises should stop trying to detect every attack and instead focus on “containing the ability of the attacker to cause damage and reduce the surface area for attack.”

Posted by Vinay Pidathala on Dec 17, 2019

According to JPMorgan Chase CEO Jamie Dimon, “The threat of cyber security may very well be the biggest threat to the US financial system.” Coupled with the fact that financial services is one of the most highly targeted industries, it’s clear financial organizations are in trouble.  Reports show a 56% year-over-year increase in digital threats targeting the sector, and according to new research, phishing is a key threat vector.

How to Mitigate Phishing Threats inYour Organization

Posted by Kowsik Guruswamy on Dec 5, 2019

From a bad actor perspective, phishing is the cheapest and easiest way to infiltrate organizations and personal information
to make a profit. By nature, humans are curious and are oft en overconfident when it comes to security. Phishing is an even greater threat for mobile users, too. Without key visual cues, like the ability to hover over a link to determine its destination, it is much easier for a user to make the simple mistake of clicking a bad link and falling victim to a phishing attempt. The popularity of social media has also made it much easier for hackers to find valid email addresses and research users’
life activities to create sophisticated, tailored phishing attacks.  From a security perspective, there are typically three approaches to solving the phishing problem – email security gateways, web proxies and security training awareness – but each has its own limitations.

Why Outsmart Cyber Attackers When You Can Remove Them Entirely?

Posted by Kowsik Guruswamy on Dec 5, 2019

Cyber threat actors have gotten smarter--or lazier--depending on your perspective. It used to be fairly
common for attackers to spend days or even weeks probing targeted networks for vulnerabilities to
exploit. Once identified, they would break down traditional cybersecurity defenses around the network
perimeter and steal as much information as they could, or cause as much chaos as possible, before the
hole was patched and they were shut out.

Today, threat actors are much more subtle. Instead of trying to break down the castle walls, they simply
steal the keys and stroll through the front door. By tricking users into willfully giving up their credentials
through spear phishing, threat actors can simply remain undetected for days, weeks or even months until
the time is right to execute their mission-- to extricate data, hold systems hostage, spy on users or all of
the above.

Is this lazy or creative? Depends on who you ask, maybe it’s a generational thing.

Isolation protects you from threats that haven’t even been discovered

Posted by Mehul Patel on Nov 8, 2019

Another day, another validation that Internet isolation really is the best cybersecurity protection out there.

Last week, Google released an urgent Chrome update to patch an actively exploited zero-day known as CVE-2019-13720, a memory corruption bug that uses a use-after-free vulnerability in audio that allows a threat actor to access memory after it has been freed. This allows anyone to cause a program to crash, execute arbitrary code, or even enable full remote code execution scenarios. Pretty serious stuff that should worry even the most secure enterprises.
