No sector or organization is immune to rapidly escalating cyberthreats, but when it comes to healthcare, the stakes couldn’t be higher Even prior to Russia’s invasion of Ukraine, there was considerable fear that military escalation would bleed (further) into cyberspace and be followed by a rash of impactful digital assaults with international implications. Organizations worldwide

Organizations worldwide should remain on high alert for cyberattacks as the risk of major cyber-spillover from the crisis in Ukraine continues to loom large Contests between states in the so-called gray zone between war and peace have been increasing for some time in cyberspace. In Ukraine, cyberattacks have been recorded more frequently over the past

Here are a few tips that will help you get your ‘go bag’ ready if you have to leave at a moment’s notice and need your communications and data to survive If you live in an area where emergencies aren’t rare (like I do; our area has one of the highest rates of fire evacuations

Press play to hear Aryeh Goretsky, Jean-Ian Boutin and Robert Lipovsky discuss how recent malware attacks in Ukraine tie into years of cyberattacks against the country Long before the first Russian soldier set foot on Ukrainian soil, the country had been a target of sophisticated digital operations spying on its officials, and sabotaging its critical

ESET researchers uncover a new wiper that attacks Ukrainian organizations and a worm component that spreads HermeticWiper in local networks As the recent hostilities started between Russia and Ukraine, ESET researchers discovered several malware families targeting Ukrainian organizations. On February 23rd, 2022, a destructive campaign using HermeticWiper targeted multiple Ukrainian organizations. This cyberattack preceded, by

ESET research discovers a previously undocumented UEFI bootkit with roots going back all the way to at least 2012 ESET researchers analyze a previously undocumented, real-world UEFI bootkit that persists on the EFI System Partition (ESP). The bootkit, which we’ve named ESPecter, can bypass Windows Driver Signature Enforcement to load its own unsigned driver, which

Yet another APT group that exploited the ProxyLogon vulnerability in March 2021 ESET researchers have uncovered a new cyberespionage group targeting hotels, governments, and private companies worldwide. We have named this group FamousSparrow and we believe it has been active since at least 2019. Reviewing telemetry data during our investigation, we realized that FamousSparrow leveraged

Misconfigurations of cloud resources can lead to various security incidents and ultimately cost your organization dearly. Here’s what you can do to prevent cloud configuration conundrums. Forget shadowy attackers deploying bespoke zero-day exploits from afar. A risk that is far more real for organizations as they embark on ambitious digital transformation projects is human error.

The campaign may last for a month, but we should remember that cybersecurity is a year-round affair The month of October is associated with a variety of themes, but it also ushers in the start of autumn and pumpkin-spiced lattes and culminates with one of the scariest days of the year – Halloween. However, beyond

Flaws in Apple Pay and Visa could allow criminals to make arbitrary contactless payments – no authentication needed, research finds Cybercriminals could make fraudulent purchases by circumventing an iPhone’s Apple Pay lock screen where the device’s wallet has a Visa card set up in so-called transit mode. The attackers could also bypass the contactless limit

A view of the T2 2021 threat landscape as seen by ESET telemetry and from the perspective of ESET threat detection and research experts Despite threats seemingly looming around every corner (I’m looking at you, Delta), the past four months were the time of summer vacations for many of us located in the northern hemisphere,
