Nobody has fully recovered from the last WannaCry ransomware attack and now there are new attacks spreading throughout the world. This time it is a threat called Petya ransomware.
Petya ransomware was a malware that was created in 2006. Now, it has been modified and the new variant has been used in the recent attacks. It locks users’ PC and encrypts files. The hackers behind the attacks ask for ransom in bitcoin in order to decrypt users’ files.
However, experts claim that Petya is not a traditional ransomware. It is more dangerous than WannaCry because it is a specific type of ransomware. Attackers ask for ransom in Bitcoin making you believe that your files will be decrypted.
But this time, it not the case. Petya’s source code revealed that it is impossible to recover and decrypt files once infected.
It can infect your PC in more ways than WannaCry or any other ransomware. It is very different from the common ransomware. It installs itself to start before Windows, causes a BSOD in Windows, and after Windows restarts, it mimics a file repair, but in reality, it encrypts the MFT(Master File Table). This type of threat will be harder to overcome. This is a cyber attack meant to sabotage and destroy users’ PC.
The attacks listed below are just some of the attacks, so it is not a surprise that Petya caused chaos around the world.
– Russia’s oil company
– Major Ukranian banks (including the Central bank) and companies
– The airport in Kiev
– British advertising agency
– U.S. pharmaceutical company Merck
– Cadbury chocolate plant in Australia
– A major shipping firm in Netherlands
Petya ransomware is a specific type of a cyber attack, which means that you will need to take extra measures in order to protect your PC.
The first thing you need to do is update your operating system. An update will improve the stability of your PC and will not be an easy target. You also need to have an antivirus and antimalware software installed on your PC and mobile phone.
Because Petya works totally different than other ransomware, most generic ransomware protection was totally ineffective against this threat and failed to protect end users worldwide.
But according to MRG Effitas, our Zemana AntiMalware proved to be the best protection against Petya ransomware. Check out the below image:
You can see the full report here.
However, few experts believe that this worldwide spreading infection is only disguised as ransomware.
It uses the NSA’s Eternal Blue Exploit and has affected many European countries including Ukraine, Poland and Germany. However, other continents were not spared as well.
All Zemana products use the same technology designed to protect you from both traditional and new types of malware. So, whether you have Zemana AntiLogger or Zemana AntiMalware, your PC will remain protected.
As we have mentioned in our previous blogs, experts predicted a high number of ransomware attacks in 2017 targeting both your PC and your mobile device.
It seems that their predictions are already coming true. Protect yourself in time with Zemana AntiMalware and enjoy the online world carefree.
Stay safe with Zemana! 🙂
Most of us have had some kind of a problem with malware in our cyber daily life. We all know how dangerous they can be. But the most annoying thing about malware is that often they come back.
Here are some tips on how to protect your PC and prevent different infections from causing you stress again.
Your antivirus is the first wall of defense against malware. Even though antiviruses are not always able to detect new threats, they are still necessary on your PC.
Don’t leave updating of your operating systems and browsers for later! Always do it in time because malware can find its way in through vulnerabilities. You can also make sure that you have automatic updating turned on.
Keep in mind that using two firewalls might cause interference with one another.
Unfortunately, many of us forget to do it but this is very important. You should find time for it once a week. Don’t forget to scan your phone regularly as well. You have also a scheduled scan option.
Below you can see where to find it on Zemana AntiMalware user interface:
Today almost everyone uses Wireless Internet Connection. Even though many of us like open networks, it is much safer to connect to a network that requires a password. Also, make sure to create a strong password for your Wi-fi network. This will prevent hackers (and your neighbours :p) from easily hacking into your Wi-fi.
Don’t click on every link that you see on websites or in your emails. If you are really curious about the link, hover over it and see where it is going to take you. Better safe than sorry!
Try using different passwords for different accounts. If you use the same password, hackers might easily figure it out and steal it. Make sure to mix lower case, upper case, different numbers and letters in order to create a strong password.
Approach emails that contain links or attachments with caution. If a message or what is being requested from you in the email seems suspicious, do not click on the provided links. So next time you receive an email saying you won 100.000$ just reject or delete such an email.
Some pop-up windows will try to convince you to buy or download something. It might offer free system scan or show an advertisement.
Your browser will probably offer you the option to block these pop ups, which you should definitely do. If not, then try to close it using the Task Manager (press Ctrl-Alt-Delete) because sometimes pressing the x button is a trap.
Invest in your additional layer of protection because it will not only keep you safe from traditional viruses but from other different types of advanced malware types as well and mostly these are available on the web now.
Install and use Zemana AntiMalware because it will not conflict with your existing antivirus software. Ranked as the best ransomware protection on the market by MRG Effitas, Zemana AntiMalware will keep you safe from massive ransomware and malware attacks 24/7.
Keep in mind these tips in your fight against malware. Don’t forget that being aware and informed makes a big difference!
Stay safe with Zemana! 🙂
Uzun lafın kısası: İkisine de ihtiyacınız var! Ne, Nasıl yani? Sakin olun, açıklıyoruz.
Antivirüs ve anti-malware arasındaki fark nedir?
Çoğunuz antivirüs ve anti-malware kelimelerini sıkça duymuşsunuzdur. Hele ki son günlerde yayılan WannaCry fidyeci zararlısıyla daha sık duyar oldunuz (Fidyeci zararlılarından kurtulmanın yoluna buradan ulaşabilirsiniz). Muhtemelen bu kavram kargaşasında kaybolmuş, anti virüs ve anti-malware arasında fark olmadığını düşünmüş olabilirsiniz. Anti-malware ile antivirüsün aynı anlama geldiğini düşünüp bilgisayarınıza anti-malware kurmamanız gerektiğini düşünüyorsanız yanılıyorsunuz. Yazının devamında antivirüs ve anti-malware arasındaki temel farkın ne olduğundan bahsedeceğiz.
Bilmeyenler için, malware İngilizce’de “malicious software”, yani şüpheli yazılım kelimelerinin kısaltmasıdır. Burada şüpheden kasıt, yazılımın kullanıcıdan habersiz istenmeyen işlemler yapma ihtimalidir. Zararlı yazılımlar verilerinize ve programlarınıza hasar verebilir, diğer bilgisayarlara yayılabilir ve gizli bilgilerinizi çalabilirler. Farklı zararlı yazılım çeşitleri vardır:
– Casus yazılımlar
– Reklam zararlıları
– Fidyeci zararlıları vs.
Buna göre virüsün, programlarınıza ve verilerinize bulaşarak yayılan bir zararlı yazılım türü olduğunu söyleyebiliriz. Virüslü bir uygulamayı çalıştırdığınızda önce virüs çalışır, sonrasında programın kendisi çalışır. Böylece virüs uygulamanın çalışmasını etkilemeden kendini gizlemiş olur.
Halihazırda kurulu antivirüs yazılımım var. Neden yanına anti-malware kurayım?
Şimdi asıl meseleye gelelim.
Antivirüsler bilgisayarınız (ve tabi ki cep telefonunuz) için başlıca yazılımlardan birisidir. Bilgisayarınızda tehditlere karşı koyan ilk duvar antivirüsler olacaktır. Bununla birlikte geleneksel antivirüs teknolojisi günümüzde sizi korumak için yeterli olmamaktadır, çünkü antivirüsler yalnızca bilinen virüs türlerine karşı etkilidir.
Her antivirüs yazılımı, içinde virüs veri tabanı bulundurur. Bilgisayarınızda virüslü uygulama çalıştırmaya kalktığınızda öncelikle bu veri tabanından kontrol edilir. Eğer varsa engellenir. Bunun anlamı, önceden tanınmamış bir virüs bulaştığında antivirüs yazılımınızın yapabileceği hiçbir şey olmayacaktır, ta ki o virüs incelenip veri tabanına eklenene kadar.
Bir diğer önemli nokta ise virüslerin tek tehdit olmaması gerçeği. Her geçen gün daha akıllı ve yaratıcı yüzlerce zararlı yazılım (virüslerin dışında) ortaya çıkmaktadır.
Peki daha önce hiç ortaya çıkmamış zararlı yazılımlardan nasıl korunabilirsiniz?
Geleneksel antivirüsler, kendi veri tabanlarında bulunmayan tehditleri tespit edemeyeceklerdir. Bu problemin cevabı anti-malware yazılımlarıdır. Anti-malware korumasına ihtiyacınız var, çünkü bu sizi bilinen ve bilinmeyen tüm tehditlerden koruyacaktır. İşte antivirüs ve anti-malware yazılımları arasındaki temel fark budur.
Zemana AntiMalware virüs tanımlarını sizin bilgisayarınızda tutmayan bir yazılımdır! Zemana AntiMalware bir şüpheli yazılım bulduğunda bunun parmak izini Tarama Bulutuna gönderir. Milisaniyeler sonra buluttaki tarama ajanları şüpheli uygulamanın zararlı olup olmadığını söyler. Eğer tespit edemezse uygulamanın tamamını buluta göndererek daha detaylı inceleme yapar.
Sonrasında Pandora teknolojisi ile yeni nesil tarama gerçekleştirerek bilinmeyen zararlılara karşı sizi güvende tutar. Zemana AntiMalware virüslere karşı veri tabanını kullanarak koruma sağlamasına ek olarak bilgisayarınızdaki her türlü şüpheli davranışı da tespit edip engeller. Sizi;
– Casus yazılımlardan
– Reklam zararlılarından
– Henüz keşfedilmemiş zararlılardan koruyacaktır.
Daha önce belirttiğimiz gibi, antivirüs yazılımları bilgisayarınızda basit ve temel koruma sağlar. Fakat bu yeterli değildir ve sizin daha iyi çözümlere ihtiyacınız var.
Zemana AntiMalware sahip olduğunuz tüm antivirüslerle uyumlu çalışacak şekilde geliştirildi. Hafiftir ve hızlı çalışır, asla bilgisayarınızı hantallaştırmaz. Zemana AntiMalware, bilgisayarınızda kesinlikle bulunması gereken bir ek koruma yazılımıdır.
Özetle, antivirüs yazılımınızı bilgisayarınızda ve telefonunuzda kullanırken (telefonunuzu da güvende tutmayı unutmayın) anti-malware ile ek koruma sağlamayı ihmal etmeyin. Aşağıda ihtiyacınız olan linkleri bulabilirsiniz.
Do I need an antimalware or an antivirus?
Straightforward answer: You need them all! Wait, what?! Ok, let’s elaborate it.
Many of you have probably heard words Anti-malware and Antivirus thousands of times, especially in recent period due to unfortunate WannaCry ransomware attacks (check here how to stay safe from ransomware attacks).
And some of you have probably been confused by the terms, believing that these two are the same thing and you couldn’t figure out what’s is the real difference between antivirus and anti-malware.
You might ask yourself: Why should you need to install antimalware, when it is just a synonym for the word antivirus, right? Well, you were wrong. Continue reading and learn the main difference between antivirus and anti-malware.
For those of you who do not know, malware is a malicious software that run on users’ PCs without their consent. Malware damages your programs and data and they can also spread to other computers and steal private information. There are different types of malware:
– ransomware etc.
Therefore, a virus is a type of malware that spreads by infecting you programs and data. It modifies your data by adding its own copies (viruses can replicate), which can also be infected. When you run an infected program, first the virus runs and then the program itself. This way the virus remains hidden.
Antivirus software is an essential protection for your PC (and your phone as well). It is the first wall of defense against threats. However, traditional antivirus technology is not enough today because it protects only from the known viruses.
Every antivirus software has its own virus database and once you get infected, the infections goes through the database and if the software recognizes the threat it blocks it. This means, that when new viruses come out somebody needs to get infected in order for the virus to get discovered.
Another very important thing is that viruses are not the only threat today. Hundreds of different malware (apart from viruses) are being created every day because hackers are becoming more and more intelligent and creative.
Your traditional antivirus protection will not recognize them because they are not in its database. The answer to this question is antimalware technology. You need an antimalware protection, because it will keep you safe from all types of known and unknown malware and this is what makes the difference between antivirus and anti-malware software.
Zemana AntiMalware is a software that does not store virus definitions on your PC! Instead, when our software finds a suspicious file, it passes the fingerprint to the Scan Cloud. Milliseconds later, the Scan Cloud marks the file as safe or malicious, or else asks AntiMalware to upload it for further examination.
After that, with its Pandora Sandbox Technology it performs another level of scanning which increases your protection from unknown malware. Instead of only waiting for its database to match and confirm the type of virus infection, Zemana AntiMalware blocks any kind of suspicious activity on your PC. It protects you from:
– Adware Infections
– Zero-day malware
As we mentioned above, antivirus software is a basic and essential protection for your PC. But this is not enough and you need to look for more.
Zemana AntiMalware is designed to be compatible with any antivirus program you have. It is lightweight and will not clutter up your drive. Therefore, Zemana AntiMalware protection is a must-have additional layer of protection.
So, to summarize, keep your chosen antivirus on your PC and phone (never forget to keep your phone safe as well) but don’t forget to install anti-malware software as well to stay fully protected. Below you can find the needed links:
On Friday (May 12, 2017) a large cyber-attack using WannaCry ransomware was launched. The attack spread to 150 countries affecting 230 000 computers, including telecommunication companies and health institutions.
WannaCry ransomware, referred to as WannaCrypt0r, WannaCrypt, or Wanna Decrypt0r, is a ransomware program that targets Microsoft Windows operating system.
It is delivered to a victim through harmful links in an email, unreliable sites and applications. Once it has been activated, the program spreads through the computer and locks all the files with the encryption.
WannaCry ransomware is believed to use the EternalBlue exploit, which was developed by the U.S. National Security Agency to attack computers running Microsoft Windows operating systems. The exploit leaked online in April 2017 by the hacker group known as The Shadow Brokers.
In just few hours this ransomware has been active, it has made many high-profile victims all over the world. Some of the countries that were hit by WannaCry are UK, Spain, Russia and China.
Unfortunately, yes. Experts believe that the number of WannaCry victims is going to rise in the next few days.
Do you have a Microsoft Windows operating system on your PC? Than you are!

Today, it is almost impossible to imagine life without mobile phones. Sometimes, we are not even aware of the amount on which we rely on our phones every day. The Internet allows us to be connected 24/7, having a constant access to different people and new information.
We use our phones for fun activities but also do to business on a daily basis. Smart devices have replaced traditional payments, so today we make financial transactions remotely using our phones.
This means, that we are constantly storing sensitive and private information. Therefore, it should not come as a surprise that hackers today are focused on our mobile phones. New threats are being created every day, not just to infect our PCs but our phones as well. However, most of people are unaware of this.
They believe they don’t need an antivirus protection on their phones, which makes them easy targets. To decrease the number of potential victims, it is important to raise the awareness about mobile security. Currently, the most popular malware is mobile ransomware and the number of its victims increases every year.
Ransomware is a type of malware that locks your computer or a mobile device, or encrypts your files, holding them ransom until you pay a fee to the cyber-criminals who hold them hostage.
However, even though we are all aware of this threat and many of us have secured our PCs, mobile ransomware has gone almost unnoticed.
Many people get easily infected because they do not know that mobile ransomware is often disguised as a legitimate mobile application or a popular game.
What is also specific about mobile ransomware is that it can hijack the PIN you used to secure your phone and disable your access to it. This way, you are powerless until you pay the hackers or unless you buy a new phone.
However, even if you pay, there is no guarantee that hackers will unlock your phone or decrypt your files.
Mobile malware is malicious software that targets mobile phones or wireless-enabled Personal digital assistants (PDA), by causing the collapse of the system and loss or leakage of confidential information.
The risk from mobile malware is constantly growing. In 2016, the most popular type was a banking Trojan, which steals money from mobile users’ bank accounts. The Trojans can also buy applications on Google Play. Once infected, it is very difficult to get rid of them.
Just like your PC, your phone needs antivirus protection as well. The risk of infection is highest for Android, where security software is already available. Make sure all your Android devices are protected by anti-malware software.
Experts are constantly warning that malware risk is real and growing. They believe that the number of threats will double in 2017 because hackers are developing smarter ways to bypass Android protection mechanisms.
While mobility is taking over don’t let mobile malware do the same! Protect your phone by install Zemana Mobile Antivirus, a lightweight antivirus app that will give you peace of mind, knowing that you are protected.
It will keep you safe from ransomware, spyware, viruses, key-loggers and zero-day malware. Zemana Mobile Antivirus is an AV-Certified Antivirus Protection. It has the fastest scanner on the market, which will allow you to detect and easily remove infections.
