Background
ESET recently reported on Industroyer2, a multi-component ICS malware used to target a Ukrainian energy company.
Background
Since January, Ukraine has been targeted by several wiper malware families. In early February, we reported on the WhisperGate wiper. Earlier this month we spotlighted HermeticWiper and IsaacWiper. Ukraine was recently under attack by yet another wiper malware. ESET announced the discovery of CaddyWiper on March 14th in a tweet. Cisco Talos followed up a day later with more information on this malware.
Background
CERT-UA, the Ukraine government’s incident response team, recently released a report on MicroBackdoor. CERT-UA did not provide further information on the scope of the incident leading to the discovery of this malware.
Background
Ukraine was recently targeted by several wiper malware families. In January, WhisperGate, which was attributed to a Belarusian threat actor group known as Ghostwriter/UNC1151, targeted Ukraine’s government, non-profit, and technology verticals. On February 23, another wiper malware dubbed HermeticWiper or FoxBlade was used to target Ukraine. On February 24, a third wiper malware was observed targeting Ukrainian entities. This new malware was dubbed IsaacWiper. ESET recently published research on HermeticWiper and IsaacWiper.

PolySwarm recently released several publications and blog posts discussing Russia-Ukraine tensions and the potential for both kinetic and cyber conflict:
Background
Last week we released a report and blog post on the Russia-Ukraine conflict, past cyber altercations between the two nations, and potential cyber implications if the current conflict escalates. In our report, we mentioned historical activity perpetrated by the threat actor group Armageddon. Palo Alto’s Unit 42 recently reported ongoing activity targeting Ukraine, which they attributed to Armageddon, also known in the industry as Gameredon or Primitive Bear. While Unit 42 did not elaborate on the magnitude or implications of these attacks, they did provide a breakdown of Armageddon’s infrastructure.
Overview
- Ongoing political tensions between Russia and Ukraine are at a breaking point, with the US and other NATO nations preparing to assist Ukraine if a military conflict arises.
- Russia and Ukraine have a long history of state-sponsored cyber conflicts, including both espionage and disruptive attacks.
- Recent cyber activity targeting Ukraine includes multiple government website defacements and WhisperGate, a wiper malware disguised as ransomware. IOCs for PolySwarm’s samples of WhisperGate are provided.
- Hacktivists recently attacked Belarus Railway to protest Russian troop transport and demand the release of “political prisoners.” This incident marked the first time hacktivists have leveraged ransomware in pursuit of political objectives.
- The cyber struggle between Russia and Ukraine has the potential to spill over and have a real-world kinetic impact. Our analysts provide a list of implications.
