On December 16, 2019, the U.S. Coast Guard disclosed a security incident at a facility regulated by the Maritime Transportation Security Act (MTSA). Forensic analysis suggests that the incident might have begun when an employee clicked on a link embedded in a phishing email.This action enabled a threat actor to set Ryuk ransomware loose on the facility’s network. Ultimately, the infection spread to all IT network files, leading Ryuk to disrupt the corporate IT network and prevent critical process control monitoring systems from functioning properly. Phishing is one of the primary infection vectors for most ransomware families, but there’s an interesting twist with this particular family. As noted by Malwarebytes, a typical Ryuk attack begins when a user opens a weaponized Microsoft Office document attached to a phishing email. Opening the document causes a malicious macro to execute a PowerShell command that attempts to download the banking trojan Emotet. This has the ability to download additional malware onto an infected machine that retrieves and executes Trickbot.

Over the last year, the education delivery model has changed rapidly. Universities have learnt to operate entirely remotely and now that learning may resume in person, a hybrid education model will likely continue. The transition from physical to online models happened so quickly that it left many IT networks exposed to serious harm from outside forces. With a hybrid model, there is likely a widening attack surface area.
A recent spate of attacks suggests that cyber-criminals are taking notice of the seemingly infinite weaknesses in learning centers defenses. But why?
One of the primary reasons is that universities operate large corporate-sized networks, but without the budgets to match. Add to that, teachers and students aren’t given training to use and connect their technology in a safe way.
To avoid falling victim to devastating cyber-attacks which often have dire consequences, we share three lessons universities need to quickly take on board.
Your Research is Valuable to Cyber-Criminals
There is a hefty price tag on some of the research conducted by universities, which makes it particularly attractive to cyber-criminals. The University of Oxford’s Division of Structural Biology was targeted in February by hackers snooping around, potentially in search of information about the vaccine the university has worked on with AstraZeneca. It’s not just gangs of cyber-criminals targeting research facilities, last year Russian state backed hackers were accused by official sources in the US, UK and Canada of trying to steal COVID-19 vaccine and treatment research.
With world-leading research hidden in the networks of universities, its unsurprising that last year over half (54%) of universities surveyed said that they had reported a breach to the ICO (Information Commissioner’s Office). The research conducted by many UK universities makes them an attractive target for financially motivated cyber-criminals and state-sponsored hackers in search of valuable intellectual property.
To add insult to injury, ransomware attackers are doubling their opportunity for pay off by selling off the stolen information to the highest bidder, causing a serious headache for the victims while potentially increasing the value of their pay-out.
Personal Information of Students and Staff Can Easily Fall into the Wrong Hands
Based on tests of UK university defenses, hackers were able to obtain ‘high-value’ data within two hours in every case. In many cases, successful cyber-attacks are followed by not only a ransom note demanding payment for the recovery of frozen or stolen data, but also the added threat of sharing any sensitive stolen information with the public.

I would like to share my experience with you and talk about viruses created for Mac devices and how to deal with them. You may say that there are no Mac viruses as Apple does not allow it. However, I may say that there are plenty of nasty malware types like adware that open new tabs in your browser, redirect you to irrelevant pages and show numerous popups.
Yes, these are not real viruses. Adware like Search Marquis cannot clone itself and infect other connected devices. It cannot encrypt your files or cause any other harm. Its activity is related only to web redirects and excessive advertising. At the same time, who knows which rogue websites adware may land you on next time. It may happen that you end up on a phishing website where cyber crooks harvest personal information that leads to identity theft.
I strongly recommend removing all adware that penetrated your device. But there is a problem here. If you want to get rid of Mac adware, you cannot quickly find a solution. If you go to google and search there how to get rid of Mac malware, you will see that all top results offer you to buy and install some shady software. In reality, these Mac antiviruses do nothing, as we know that the Apple ecosystem does not allow apps to access other apps' data. No antivirus can really scan and check your files.
How to remove Mac malware
If your system is infected with adware and you do not know how to get rid of it, you may try to call Apple and ask what to do. You can find their phone number here: support.apple.com/en-gb/HT201232#us-ca.
Another option is to try your luck on Apple communities. Thousands of tech enthusiasts help uses with their problems there. Here is a sample thread: discussions.apple.com/thread/8226644.
There are other options too. Apple operating systems are not very difficult to use, and any person can remove adware manually by going through step-by-step guides posted on numerous malware removal websites. Here is a guide by BitAdvisors.com on how to remove Search Marquis malware.
Most rogue software works by exploiting bugs and vulnerabilities in your computer's operating system. And macOS has its own bugs too. To fix these vulnerabilities, Apple periodically releases operating system updates. To date, macOS has not proved attractive enough for cybercriminals and evil developers to flood it with malware.
To stays away from any surprises, it is recommended to update your OS as well as all apps installed regularly.
You should never install apps from unofficial app stores not controlled by Apple.
One of the ways for adware to penetrate your Mac computer is through bundled installs. You download and install a very useful app that is often free, but in reality, you get several apps. People never read user agreements written in small print. There it can be noted that you agree to install additional tools and provide some rights to them. Whenever you install something, be careful and read user agreements, and do not miss additional unnecessary software.
Do not install any software without urgent necessity. Any additional software widens the attack surface.
To be able to do bad things, current Mac malware requires users to perform some actions – grant rights. So, be careful with allowing any app to access your data, change settings, etc.
One more wise move is to make backups. iCloud or ordinary flash drives will help you not lose your data in case of a system glitch or malware attack.
Final advice - do use VPNs. Your connection will be encrypted, and attackers will not be able to find where you are actually located or what data your traffic consists of.

Researchers at security firms including Sentinel One and Drago’s have been mystified by a piece of code named Ekans or Snake, over the last month. Drago’s publically released its full report on Ekans Ransomware that has recently inflicted Industrial Control Systems and these are some of the most high-value systems that bridge the gap between digital and physical systems. In the history of hacking, only a few times a piece of malicious code has been marked attempting to intrude Industrial Control Systems. Ekans is supposed to be the first Ransomware with real primitive capability against the Industrial Control Systems, software, and hardware used in everything from oil refineries to power grids. Researchers say this ransomware holds the capability to attack ICS by Honeywell and GE as well.
