NotPetya isn't your typical ransomware

Ransomware skull

Ransomware is often considered a somewhat low-stakes annoyance: in most cases, the data itself doesn’t leave the network and public operations aren’t compromised. NotPetya changed the game -- it’s shown us the potential of how wildly damaging ransomware infections can be from here on out. It can feel like science fiction at times, but is now utterly reasonable to consider any data or device with a CPU and memory on your network as something that can be held hostage by ransomware.

Ransomware has proven to be a lucrative endeavor: more and more central and important systems are being targeted. Cryptolocker targeted family photos. Later variants somewhat indiscriminately encrypted any user file they had access to -- and last month, we saw NotPetya locking out machines entirely.

Ransomware skull

The ransomware attacks that make the news are the ones like WannaCry and NotPetya that spread rapidly and affect many businesses.

But there's a new breed of manual ransomware attack happening that seeks to pick its victims much more selectively with a view to causing maximum disruption. We spoke to Roy Fisher, incident investigator at cyber security company MWR to find out more.

Goldeneye attack is not ransomware

Attack button

On June 27, reports of a rapidly spreading ransomware attack started to emerge from Ukraine. The speed at which critical infrastructure networks were shutting down pointed to a ransomware application with a wormable component, whose virality called to mind the WannaCry ransomware. In less than three hours, the infection crippled banks, ATMs, public transport and an airport, as well as utilities provider Kyivenergo. Then it spread outside the Ukraine.

As multiple critical infrastructure networks reported major blackouts, Bitdefender started an internal investigation over isolated malware samples to trace the attack’s origin and better understand what it targeted, and how.

Web hosting company pays $1 million after Erebus ransomware attack

Cash for ransomware

The cost of a ransomware attack can be pretty substantial. Businesses that are not well prepared are looking at lost revenue from downtime and massive damage to their reputation, not to mention a pretty hefty ransom bill as well.

For web hosting company Nayana, that was $1 million. Nayana, which is based in South Korea, had 153 of its Linux-based servers infected by the Erebus ransomware on June 10. The attack affected roughly 3,400 customers that relied on its services for hosting websites, databases and multimedia content.
