#ESETresearch discovered a supply-chain attack performed by #Lazarus APT group against South Korean 🇰🇷 internet users. @cherepanov74 @pkalnai welivesecurity.com/2020/11/16/laz… 1/7
WIZVERA VeraPort software is often used on internet banking and government websites in 🇰🇷 South Korea. The purpose of this software is to install additional security software required by some of these websites. 2/7
The attackers abused a combination of WIZVERA VeraPort software and compromised South Korean websites with VeraPort support, to deploy Lazarus malware. 3/7
The #Lazarus malware pushed via this supply chain was signed with code-signing certificates issued to two different companies. 4/7
This #Lazarus malware and campaign have similarities with the activity previously published by 🇰🇷 Korea Internet & Security Agency in their Operation BookCodes reports. 5/7
One #Lazarus sample delivered via this supply-chain attack contains the string ohayogonbangwa!!. This is the romaji version of the 🇯🇵 Japanese phrase おはようこんばんぐぁ, which translates as “Good morning, good evening”. 6/7
IoCs are available on our GitHub repository: github.com/eset/malware-i… #ESETresearch 7/7

#ESETresearch unearths modus operandi of the elusive #InvisiMole group, digging up their arsenal used to stay invisible. Our investigation also shows previously unknown ties between InvisiMole and #Gamaredon groups welivesecurity.com/2020/06/18/dig… @cherepanov74 @zuzana_hromcova 1/9
#InvisiMole #APT group resurfaced in targeted attacks against high-profile organizations in Eastern Europe, targeting military sector and diplomatic missions. We previously documented their two feature-rich backdoors RC2CL and RC2FM; now we reveal the rest of their TTPs. 2/9
We discovered that the most interesting targets of #Gamaredon are upgraded to far stealthier #InvisiMole spyware, with Gamaredon’s .NET downloader delivering InvisiMole’s TCP downloader. This cooperation allows InvisiMole to devise creative ways to operate under the radar. 3/9

#ESETresearch analyzed operation #Interception, a new espionage campaign targeting aerospace & defense companies in Europe and the Middle East. Initial contact was made via #LinkedIn, where attackers approached targets with fake job offers @jiboutin welivesecurity.com/2020/06/17/ope… 1/5
The attackers sent a password protected RAR archive containing a LNK file responsible for showing a decoy PDF and downloading additional malware. In some cases, this archive was sent directly through #LinkedIn instant messenger. #ESETresearch 2/5
While the victim was being deceived by the decoy PDF, a scheduled task was created, launching WMIC to execute a script embedded in a remote XSL file. This enabled the attackers to get their initial foothold inside the targeted company and gain persistence on the computer. 3/5

#ESETresearch stumbled upon strange samples which use the packer we described in publications on the #Winnti Group. The payload in these samples is an implant attributed to Equation. It is known as PeddleCheap according to the project names seen in the Shadow Brokers leaks. 1/8
Those samples were first seen in 2017, one year before it was used in the compromised games in 2018 (welivesecurity.com/2019/03/11/gam…). They are 8b8d2eb8de66890f4c0950ccb3fff95b0f42b9e1 and b48beb5e49976294287b1d6910d7445db83e5cf2. #ESETresearch @marc_etienne_ 2/8
These particular executables do 3 things: launch the legitimate Adobe Flash installer, copy itself to %TEMP%\micrit.exe and start PeddleCheap. #ESETresearch @marc_etienne_ 3/8
