Threat actors are using the hacked accounts for phishing scams targeting European government officials to steal Ukrainian refugees and supply data.
A newly discovered phishing campaign uses compromised email accounts of Ukraine’s army personnel to steal data from European governments entities. It is worth noting that the email addresses in the discussion are private email accounts of Ukrainian military personnel offered by @i.ua and @meta.ua.
The findings come soon after the State Service of Special Communication and Information Protection of Ukraine issued a warning last week regarding the possibility of phishing attacks against its military officials to steal sensitive private data.
About Asylum Ambuscade
The Sunnyvale-based enterprise security firm, Proofpoint, has disclosed details of a new phishing campaign where nation-state-sponsored threat actors aim to steal the Ukrainian refugee movement and supply related data.
They are targeting European government entities to obtain intelligence information. The campaign was detected on 24 February 2022. The company dubbed the social engineering-based campaign as Asylum Ambuscade.
Malicious Emails Used to Hack Data
In the report, Proofpoint researchers Michael Raggi and Zydeca Cass wrote that threat actors use emails loaded with a malicious macro attachment (XLS file). The content is related to the Emergency Meeting of the NATO Security Council, held on 23 February.
The malicious attachment attempts to download Lua-based malware known as SunSeed. The primary objective of attackers is targeting European government officials responsible for managing transportation, budget/finance allocation, and population movement in Europe.
A key aspect of Asylum Ambuscade is that compromised email accounts of Ukrainian military service personnel are used to distribute malware-laced emails onto infected hosts. SunSeed serves as a downloader to establish communications with the attacker-controlled server to extract the next-stage payload.
Possible Perpetrator?
Proofpoint didn’t associate the new phishing campaign with any specific hacking group or threat actor. The company noted in its blog post that the two sets of attacks they observed indicate similarities between the timeline overlaps, phishing lures used in the campaign, and the patterns of victimology with a Belarusian state-backed group known as TA445 (aka UNC1151 and Ghostwriter.
The social engineering lures utilized in this phishing campaign were very timely, following a NATO Security Council meeting on 23rd February 2022 and a news story about a Russian government ‘kill list’ targeting Ukrainians that began circulating in Western media outlets on 21st February 2022.
