#ESETresearch has discovered a zero-day vulnerability in WinRAR, exploited in the wild by Russia-aligned #RomCom @dmnsch @cherepanov74 welivesecurity.com/en/eset-resear… 1/7
ESET is hot on mobile security—Android adware detection rose 160% in H1 2025, with a novel threat called Kaleidoscope accounting for 28%. It uses an "evil twin" trick to relay malware, hitting regions reliant on unofficial apps the hardest.
In 2009 while watching Stewart Little (1999), Hungarian art historian Gergely Barki, saw the painting "Sleeping Lady with Black Vase" by Róbert Berény. It had been missing for 90 years and had been used as a prop. It was the original.
FaceID on iPhone 13 mini stopped working cause of screen protector. I replaced the protector with a new one (same brand and type) and it still fails. Started to have issues cca a week ago, worked fine before for more than a year. Any1 knows more about this? Is it caused by 18.5?
🚨 Since 2018, @ESETresearch has tracked the evolution of #Danabot — a powerful malware-as-a-service operation. Now, as part of a joint takedown effort, ESET has helped partially disrupt the operation's infrastructure, leading to the identification of individuals responsible.
The #FBI and #DCIS disrupted #Danabot. #ESET was one of several companies that cooperated in this effort. welivesecurity.com/en/eset-resear… 1/6
#ESETresearch, in collaboration with #Microsoft, BitSight, Lumen, Cloudflare, CleanDNS, and GMO Registry, has helped disrupt #LummaStealer – a notorious malware-as-a-service infostealer. @JamesTomanek welivesecurity.com/en/eset-resear… 1/5
👏👏👏👏
Since in the last 48 hours I have received support not only from my home country 🇨🇿, but from many other countries, once again in English. Thank you to everyone who supported me after repeated threats from former Russian President Medvedev. I appreciate it very much. And it also…
Big day for corrupt insiders.
This is the biggest pump and dump scheme in the history of the world.
