Earlier this week, we saw another mass ransomware attack happen, less than two months after the WannaCry outbreak. In the hours and days after the attack, this strain was given many different names, including Petya, Petna, NotPetya, EternalPetya, Nyetya, and many more. We originally referred to it as Petya-based, but for simplicity, let’s call it Petna.
Further to reports of a massive cyber attack hitting a number of companies in Ukraine, including banks, energy companies and transport services as well as the government, we believe this is another example of the Petya-based ransomware, which was first…
One of the many reasons Avast acquired AVG last year was our mutual confidence that we’d be better together, with improved security quality, reliability, and performance. The combination of Avast’s CyberCapture and our artificial&nb…
Selecting the right security solution to protect your devices isn’t always an easy decision to make – whether you’re a consumer or a larger organization. Luckily, there are many independent testing laboratories who do their job at testing security products well, so end customers have a way to compare and select a solution that suits their needs best. It’s not often we see a new kid (tester) on the block.
Artificial intelligence (AI) is the hottest new trend that’s been around for years. While that may sound like an oxymoron, there’s a reason the buzz around AI and its subset, machine learning, hasn’t quieted down and is likely to continue for a long time. It’s uniquely critical in our fight against the ever-growing number and variety of cyberthreats and vital to our ability to scan for and remove malware.
I’ve been in the business of defeating malware for more than 25 years. Having started as a part-time developer at Avast, which was called ALWIL at the time, I found myself hooked by the cat-and-mouse game of white hat against black hat, and I still am today, as Avast’s Chief Technology Officer.

WannaCry, the worst ransomware outbreak in history, gained a lot of media attention, but WannaCry isn’t the only malware strain spreading on a massive scale. One of them is Adylkuzz, a cryptocurrency miner, that has been infecting PCs around the world, just like WannaCry.
While last Friday wasn’t Friday the 13th, it sure seemed like it. PCs around the world, including those belonging to hospitals and government agencies, were hit by the WannaCry (AKA WanaCrypt0r, or WCry) ransomware, causing chaos. Up until now we have seen more than 250,000 detections in 116 countries. About 15% of our more than 400 million users worldwide haven’t patched the MS17-010 vulnerability, which could have made them vulnerable to this attack, if they didn’t have Avast protecting them.
We have observed a massive peak in WanaCrypt0r 2.0 (aka WCry) ransomware attacks today, with more than 57,000 detections, so far. According to our data, the ransomware is mainly being targeted to Russia, Ukraine and Taiwan, but the ransomware has succe…
