Five Data Wipers Attack Ukrainian News Agency

Ukrainian cyber-authorities have identified numerous items of harmful malware that, earlier this month, have been utilized in an attack concentrating on the country’s countrywide information company (Ukrinform).

The country’s Computer system Emergency Reaction Team (CERT-UA) exposed in an update that the attack was publicized on a Telegram channel “CyberArmyofRussia_Reborn” on January 17.

Right after currently being asked by Ukrinform to look into, a staff at CERT-UA found out five scripts – “the operation of which is aimed at violating the integrity and availability of data (writing data files/disks with zero bytes/arbitrary knowledge and their subsequent deletion).”

The danger actors are considered to have received unauthorized remote access to the Ukrinform network as much back as December 7 2022, but bided their time just before launching the harmful malware.

In truth, the five samples contain one legit Windows utility, SDelete.

“It was discovered that the attackers created an unsuccessful endeavor to disrupt the regular operation of users’ computers making use of the CaddyWiper and ZeroWipe malicious plans, as well as the genuine SDelete utility (which was meant to be introduced employing ‘news.bat’),” the report noted.

“At the identical time, for the function of centralized distribution of destructive plans, a group plan item (GPO) was developed, which, in switch, ensured the generation of corresponding scheduled duties.”

The whole checklist of malware/computer software made use of in the attack is: CaddyWiper, ZeroWipe, AwfulShred, BidSwipe and SDelete.

CaddyWiper was very first uncovered back in March 2022 at the starting of Russia’s invasion. Researchers profiling it at the time explained it did not share any attributes with previous destructive malware used by Russia, these types of as HermeticWiper, IsaacWiper and WhisperGate.

Like the Ukrinform attack, it was deployed via a GPO, indicating the menace actors experienced control of the target’s network.

“Taking into account the outcomes of the study, we consider it is achievable to state that the cyber-attack was carried out by the UAC-0082 (Sandworm) group, whose routines are related with the Russian Federation,” the report concluded.

Functioning out of the Russian armed service (GRU), Sandworm has been joined to a number of damaging strategies in the previous, like attacks on Ukrainian electric power infrastructure in December 2015 and the notorious NotPetya worm of 2017.
