Pro-palestinska in pro-muslimanska hektivistična skupina RipperSec dosega nove “mege” kibernetske napade s svojim orodjem MegaMedusa

Pro-palestinska in pro-muslimanska malezijska hektivistična skupina RipperSec, ustanovljena junija 2023, je na svojem Telegram kanalu zbrala več kot 2.000 naročnikov.

RipperSec sodeluje z mednarodnimi skupinami, kot so Tengkorak Cyber Crew in Stucx Team, in se ukvarja s kibernetskimi napadi, kot so vdori v podatke, uničevanje spletnih strani in napadi z razpršeno zavrnitvijo storitve (DDoS).

Njihove glavne tarče so države, ki jih zaznavajo kot podpornike Izraela, s ciljem motiti operacije, opozarjati nase in izražati solidarnost s palestinskimi in muslimanskimi vzroki.

Kibernetska skupina RipperSec je prevzela odgovornost za 196 DDoS napadov na Izrael, Indijo, ZDA, Združeno kraljestvo in Tajsko med januarjem in avgustom 2024.

MegaMedusa, javno dostopno spletno orodje za DDoS napade, ki ga je razvila RipperSec, je bilo uporabljeno za izvedbo teh napadov. Izveden z uporabo Node.js, izkorišča svoje asinhrone in neblokirajoče I/O zmogljivosti za učinkovito upravljanje več omrežnih povezav, kar ga naredi močno orožje za obsežne DDoS napade.

Primarno je napadala vladne, izobraževalne, poslovne in finančne spletne strani, kar kaže na prednost kritične infrastrukture.

MegaMedusa uporablja različne tehnike naključnosti za prikrivanje svojih napadnih zahtev, zaradi česar jih je težko zaznati in omiliti, vključno z naključno nastavitvijo glav, poti zahtevkov, metod, piškotkov, IP naslovov, TLS/SSL konfiguracij, nastavitev HTTP/2 in uporabe proxijev.

Poleg tega orodje podpira odprte proxije in ponuja združilnike za pridobivanje svežih seznamov proxijev iz javno dostopnih virov, zaradi česar je MegaMedusa močno orodje za izvajanje napadov z razpršeno zavrnitvijo storitve (DDoS).

MegaMedusa, orodje za DDoS napad, trdi, da obide varnostne izzive, vključno s CAPTCHAji, vendar je njena implementacija omejena, saj se primarno zanaša na naključnost in uporabo proxijev za izogibanje zaznavanju, namesto neposrednega reševanja CAPTCHAjev.

Medtem ko vključuje nekatere osnovne elemente ravnanja s CAPTCHAji, mu manjkajo napredne zmožnosti, kot so strojno učenje ali avtomatizacija brskalnika. Skupina RipperSec verjetno uporablja bolj dovršene različice MegaMeduse, kot kaže njihov oglasni video.

Spletni DDoS napadi uporabljajo proxije za prikrivanje izvora zahtev in zaobiti mehanizme zaznavanja. Proxiji delujejo kot posredniki, vzpostavljajo TCP povezavo s tarčo in posredujejo zahteve.

Knjžnice Node.js, kot je https-proxy-agent, poenostavljajo implementacijo proxijev, vendar MegaMedusa uporablja naravni pristop za večji nadzor, kar omogoča napadalcem ustvarjanje velikega števila zahtev iz različnih krajev, preobremenjevanje tarč in motenje storitev.

Izboljšave HTTP protokola, kot sta pipelining in multipleksiranje, so povečale učinkovitost napadov. Medtem ko je pipelining omejen z blokiranjem na začetku vrstice, multipleksiranje omogoča hkratne zahteve preko ene TCP povezave.

Ranljivosti, kot sta Rapid Reset HTTPS/2 in HTTP/2 Continuation, so izkoriščale te izboljšave za DDoS napade. Odprti in komercialni proxiji, pogosto kompromitirane naprave v rezidencah ali strežniki, napadalcem zagotavljajo rezidenčne IP naslove, kar omogoča izogibanje zaznavanju.

Hekerja so izkoristili slabo konfigurirane AWS .env datoteke za napade na 110.000 domen.

Oblak na udaru: Hekerji izkoristili napačno konfigurirane AWS .env datoteke za obsežne napade

Napadalci so izkoristili izpostavljene okoljske spremenljivke v napačnih konfiguracijah AWS .env datotek, da so zaklenili podatke, shranjene v S3 vsebnikih. S pomočjo avtomatizacije so ciljali na več kot 100.000 domen.

Varnostni neuspehi opozarjajo na pomembnost robustne avtentikacije

Njihov uspeh je bil posledica več varnostnih neuspehov uporabnikov oblaka, vključno z uporabo dolgoročnih poverilnic in pomanjkanja arhitekture z najmanjšimi privilegiji. Ti primeri poudarjajo pomembnost robustne avtentikacije in nadzorov dostopa, šifriranja podatkov, varnega upravljanja konfiguracije ter celovitega spremljanja in beleženja v oblačnih okoljih za zmanjšanje takšnih napadov.

Sprva so napadalci pridobili dostop do okolj AWS organizacij in nato pregledali več kot 230 milijonov edinstvenih ciljev za občutljive podatke. Osredotočili so se na 110.000 domen in pridobili več kot 90.000 edinstvenih spremenljivk iz .env datotek, med katerimi je bilo 7.000 povezanih z oblačnimi storitvami in 1.500 povezanih z računi na družbenih omrežjih.

Večplastna infrastruktura omogočila učinkovitost napadov

Z uporabo večplastne infrastrukture so napadalci izkoristili VPS končne točke, omrežje Tor in VPN za izvidovanje, začetni dostop, lateralno premikanje in iztovor podatkov.

Igralci groženj izkoriščajo široko izpostavljenost .env datotek za pridobitev nepooblaščenega dostopa do občutljivih informacij. Te datoteke vsebujejo pogosto trdo kodirane poverilnice in javno gostujejo na nezavarovanih spletnih aplikacijah, zaradi česar so lahke tarče za napadalce.

Amazon Web Services in pomanjkljiva varnost

Nedavne kampanje so pokazale učinkovitost te tehnike, saj so napadalci uspešno pridobili dostopne ključe AWS IAM iz izpostavljenih .env datotek. Napadalci so izkoristili te poverilnice, da so pridobili začetni dostop do oblačnih okolij žrtev.

Na žalost niso imeli skrbniki dostopa do vseh virov, kar je napadalcem omogočilo stopnjevanje njihovih privilegijev. Z izkoriščanjem dovoljenja za ustvarjanje in spreminjanje IAM vlog in politik so ustanovili nove IAM vire z neomejenim dostopom.

Pred stopnjevanjem svojih privilegijev so napadalci uporabili GetCallerIdentity API za preverjanje identitete in dovoljenj, povezanih s kompromitiranimi poverilnicami.

Raba AWS API zahteva in Lambda funkcij

Sprva so uporabili AWS API zahteve ListUsers in ListBuckets za zbiranje informacij o ciljnem AWS računu. Nato so stopnjevali svoje privilegije z ustvarjanjem nove IAM vloge z AdministratorAccess in jo priložili vlogi.

Čeprav jim ni uspelo ustvariti infrastrukture skladov EC2, so uspešno ustvarili AWS Lambda funkcije z uporabo API klica CreateFunction20150331, ki so jih uporabili za izvajanje bash skripte, ki je iskala morebitne cilje v računu.

Ozaveščanje o tveganjih in najboljših praksah za varnost v oblaku

Kampanja za izsiljevanje v oblaku poudarja tveganja, povezana z zanemarjanjem najboljših praks za varnost v oblaku. Izpostavljene .env datoteke, ki vsebujejo občutljive informacije, kot so API ključi in poverilnice, lahko izkoristijo zlonamerni akterji.

Za zmanjšanje teh tveganj bi se organizacije morale izogibati shranjevanju .env datotek v sistem za nadzor različic, uporabljati okoljske spremenljivke, izvajati robustne nadzore dostopa, izvajati redne revizije in uporabljati orodja za upravljanje skrivnosti.

💡 Namig dneva: Redno preglejujte in posodabljajte varnostne konfiguracije vaših oblačnih storitev ter izogibajte shranjevanju pomembnih poverilnic v javno dostopnem formatu.

Analiza kampanje

Analiza kampanje, ki jo je izvedel Cyble je razkrila potencialne indikatorje kompromisa (IOC) v različnih kategorijah. En sam URL, povezan z lambda funkcijo, se morda zdi neškodljiv. Vendar je bilo označeno znatno število IP naslovov, med njimi Tor exit točke, VPS končne točke in VPN končne točke.

Ti IP naslovi sugerirajo, da kampanja morda izkorišča anonimne storitve in kompromitirane strežnike, da prikrije svoj izvor in dejavnost. Poleg tega je bil identificiran SHA256 hash za skripto z imenom Lambda.sh, ki se lahko uporabi za nadaljnjo preiskavo.

Prav tako je pomembno, da ne odpirate sumljivih povezav ali prilog v elektronski pošti, saj lahko te vsebujejo zlonamerno programsko opremo.

💡 Namig dneva: Redno posodabljajte svojo programsko opremo in vklopite dvofaktorsko avtentikacijo za zaščito vaših računov.

Oglaševanje in javna obvestila

Javna obvestila od pristojnih organizacij, kot so Microsoft, Adobe in Google, prav tako igrajo pomembno vlogo pri zaščiti uporabnikov. Te organizacije so že izdale varnostne popravke, vendar nekatere ranljivosti še vedno ostajajo. Zato je pomembno, da uporabniki sledijo navodilom teh organizacij in redno posodabljajo svoje sisteme.

Učinkovitost varnostnih programov

V preteklosti smo pogosto videli, da so učinkoviti varnostni programi rešili situacijo, vendar tokrat ni dovolj. Zato je ključnega pomena, da se zavedamo pomembnosti varnostnih posodobitev in jih redno izvajamo. Delujoči požarni zidovi in posodobljeni antivirusi še vedno ostajajo prva linija obrambe, vendar je potrebno dodati še druge ukrepe za celovito zaščito.

Za boljšo zaščito pred takšnimi napadi obstaja tudi možnost uporabe VM (Virtual Machine) tehnologije, ki oddvojujeta operacijski sistem od glavnega sistema. S tem se zmanjša tveganje za posredni dostop preko ranljivosti v programski opremi. Prav tako se priporoča uporaba vrstnega reda za dostop do informacij, kar pomeni, da imajo uporabniki dostop samo do tistih virov, ki jih resnično potrebujejo.

Zaključek

Situacija, v kateri so se znašli uporabniki po svetu zaradi zero-day napak, je resna in zahteva takojšnje ukrepanje. Kitajski hekerji zmorejo izkoristiti vsakršno priložnost, zato moramo biti vsi uporabniki še posebej pazljivi. Redna posodobitev programske opreme, uporaba naprednih varnostnih rešitev in upoštevanje javnih obvestil so koraki, ki jih moramo upoštevati, da bi zagotovili varnost svojih podatkov in informacij.

V tem negotovem obdobju je ključnega pomena, da sodelujemo z organizacijami, ki skrbijo za informacijsko varnost, poslušamo njihove nasvete in ne podcenjujemo nevarnosti, ki jih prinašajo zero-day napake.
