Code similarity is a common and powerful way to cluster malware samples and make connections between seemingly unrelated malware families. Although it sounds simple, it is actually a complex problem and is hard to automate at scale without generating false positives. 1/
Blindly trusting code similarity can get one to make connections when there are none. This yields erroneous conclusions and can create very wrong media headlines. 2/ Image
An example of wrong use of code similarity was published by Cluster25 recently, where they connect #IsaacWiper to various other malware families. cluster25.io/2022/05/03/a-s… 3/

Za měsíc války se UKR stala terčem bezprecedentního počtu destruktivních kyberútoků. Některým se podařilo zabránit, jiné pocítil i zbytek Evropy.
Pokusím se z otevřených zdrojů vypíchnout to nejdůležitější, co se od počátku invaze odehrálo v UKR kyberprostoru:🧵1/10
První závažný kyberútok zasáhl UKR ještě před invazí – už 13. ledna. Malware #WhisperGate se maskoval jako kriminální ransomware, který napadené systémy za poplatek odšifruje. Ve skutečnosti šlo o wiper - data nevratně mazal a ničil přístroje. 2/10

Bezprostředně před a po začátku RU invaze 24. února vypověděly službu UKR počítačové systémy napříč několika sektory, včetně vládního, finančního a leteckého. Na vině byly ničivé kyberútoky využívající dva různé wipery - #HermeticWiper a #IsaacWiper. 3/10

#BREAKING #ESETresearch warns about the discovery of a 3rd destructive wiper deployed in Ukraine 🇺🇦. We first observed this new malware we call #CaddyWiper today around 9h38 UTC. 1/7 ImageImage
This new malware erases user data and partition information from attached drives. #ESET telemetry shows that it was seen on a few dozen systems in a limited number of organizations. 2/7
CaddyWiper does not share any significant code similarity with #HermeticWiper, #IsaacWiper or any other malware known to us. The sample we analyzed was not digitally signed. 3/7
