Maalin kasta malware cusub ayaa diyaar u ah inuu galo kombayutarkaga. Iyada oo ay sii kordhayaan khataraha software-kan xaasidka ah, waxaan u baahanahay inaan adkeyno amnigeena oo aan hubinno in nala ilaaliyo. Boostadani waxay ku saabsan tahay ilaalinta MBR -ga kombayutarka , waxaanan ka faa'iidaysan doonaa caawinta kombuyuutar yar laakiin awood badan oo darawal ah oo la yiraahdo MBR Filter . Isticmaal qalabkan si aad uga ilaaliso kombiyuutarkaaga MBR malware & ransomware.

Waa maxay MBR & MFT

MBR ama Master Boot Record waa meesha yar ee loo qoondeeyay saxanka kaas oo kaydiya macluumaadka ku saabsan qaybaha saxanka iyo habaynta nidaamka faylka. Erayada fudud, MBR ayaa mas'uul ka ah kicinta nidaamkaaga hawlgalka iyo kaydinta iyo soo celinta xogta muhiimka u ah taas. MBR waxa kale oo ay haysaa miiska loo yaqaan " Master Partition Table " kaas oo tilmaamaya qaybaha lagu sameeyay diskka adag. MBR guud ahaan waxa lagu kaydiyaa qaybta koowaad ama si kale haddaynu si kale u dhigno xagga hore ee xog kasta oo kale oo ku jirta Hard Disk-ga.

Waxaa jira xog kale oo la yiraahdo MFT ama Master File Table . MFT waa xog kaydisa macluumaadka ku saabsan fayl kasta ama hagaha nidaamkaaga. Ilaalinta MBR iyo MFT labadaba aad bay lagama maarmaan u tahay.

Software-ka xaasidka ah, badanaa Rootkits wuxuu isku dayi karaa inuu meesha ka saaro bootloader-ka oo uu farageliyo kombiyuutarka. Petya , ransomware-ka ugu baahsan ee maalmahan wuxuu isku dayaa inuu sireeyo MFT ka dibna ku qasbo dhibbanayaasha lacagaha Bitcoin si ay dib ugu helaan. ^(Bitcoin)Horumarinta rootkits-kan iyo Ransomware , waxaan u baahanahay inaan ilaalino bootloader.

Shaandhaynta MBR

MBR Filter waa darawal yar oo loo qoray si uu wax uga qabto weerarrada ku jira diiwaanka boot. Waxaa soo saaray 'Cisco Talos' waxaana lagu sii daayay bilaash iyadoo la raacayo shatiga il furan. Waxaad soo dejisan kartaa koodhka isha, samayn kartaa isbeddelo, oo aad adigu isku dubaridi kartaa ama waxaad soo dejisan kartaa nooca la sii diyaariyay. Filterka MBR^{(MBR Filter)} wuxuu ka hortagi karaa malware kasta, ransomware, ama rootkit-ka inay wax u dhimaan diiwaanka boot-ka oo ay isbedel sameeyaan.

Ilaali Diiwaanka Bootka Master-ka

Waxa uu MBR Filter sameeyo waxa uu kiciyaa goobaha amniga oo u baahan nidaamka in uu ku xidho Mode Safe si uu isbedel ugu sameeyo qaybta kowaad ama rikoodhka boot. Adigoo isticmaalaya darawalkan, waxaad hoos u dhigi kartaa gelitaanka MBR iyo MFT inta badan software-ka xaasidnimada leh. Dhammaan isku daygoodu faa'iido ma yeelan doonaan marka aad MBR Filter ku rakibto kumbuyuutarkaaga.

Sida loo rakibo filterka MBR
^{(How to install MBR Filter)}

Ku rakibida Filterka MBR^{(MBR Filter)} waa wax fudud. Tag shabakada MBR Filter oo soo deji kala duwanaanshaha u dhigma qaab dhismeedka nidaamkaaga. Soo saar waxa ku jira faylka zip-ka, waxaana jiri doona laba fayl oo diyaar ah.

Midig ku dhufo 'MBRFilter.inf' oo dooro rakib. Rakibadu si dhakhso ah ayey u dhammaan doontaa, waxaadna u baahan doontaa inaad dib u bilowdo kombayutarkaaga si isbeddeladu u dhacaan.

Filter-ka MBR^{(MBR Filter)} si ula kac ah waa ay adag tahay in meesha laga saaro si malware-ka uusan u saari karin oo uu u galo MBR . Haddii aad rabto in aad tijaabiso in MBR Filter uu shaqaynayo iyo in kale, waxaad soo dejisan kartaa AccessMBR . Waxay akhrin doontaa qaybta '0' ee Physical Drive 0 waxayna ku qori doontaa qaybtaas dib u hubinta haddii Filterka MBR^{(MBR Filter)} uu si sax ah u shaqeeyo iyo in kale.

Erayada Xidhitaanka^{(Closing Words)}

Hubi^(Make) in aad rakibtay Filterka MBR^{(MBR Filter)} haddii aad rabto ka ilaalin buuxda oo ka dhan ah ransomware sida Petya . Haddii aad waligaa rabto inaad isbedel ku samayso MBR , waxaad kombuyuutarkaaga ku dhejin kartaa qaab badbaado leh oo samee.

Riix halkan^(here)(here) si aad u soo dejiso filterka MBR^{(MBR Filter)} . Si taxaddar^(caution) leh u isticmaal qalabkan – doorbidaya marka hore jawiga tijaabada, maadaama ay la timaado cawaaqib xun.

Protect your computer's Master Boot Record with MBR Filter

Every day a new malwаre is rеady to tаke on your compυter. With the inсreasing risks of these malicious software, wе need to tighten up our security and make sure we are protectеd. This post is all aboυt protecting the MBR of a computer, and we will be taking the help of a small but powerful driver software called MBR Filter. Use this tool to protect your computer against MBR malware & ransomware.

What is MBR & MFT

MBR or Master Boot Record is the small allocated space on disk which stores the information about disk partitions and file system configuration. In simpler words, MBR is responsible for booting up your operating system and storing and retrieving data essential for that. MBR also maintains a table called “Master Partition Table” that identifies partitions made on a hard disk. MBR is generally stored in the first sector or in other words at the front of every other data in the hard disk.

There is another database called MFT or Master File Table. MFT is a database that stores information about each and every file or directory on your system. Protecting both MBR and MFT is very much necessary.

Malicious software, usually Rootkits can try to override the bootloader and tamper with the computer. Petya, the most prevalent ransomware these days tries to encrypt the MFT and then force victims into Bitcoin payments for regaining access. With the advancement of these rootkits and Ransomware, we need to protect the boot loader.

MBR Filter

MBR Filter is a small driver written to tackle the attacks on the boot record. It is developed by ‘Cisco Talos’ and released for free under an open-source license. You can download the source code, make changes, and compile it yourself or you can download the precompiled version. MBR Filter can prevent any malware, ransomware, or rootkit from tampering with boot records and making changes.

Protect Master Boot Record

What MBR Filter does is triggers security settings and require the system to boot in Safe Mode to make any changes to the first sector or the boot record. Using this driver, you can cut down the access to MBR and MFT for most of the malicious software. All their attempts will go useless once you have MBR Filter installed on your computer.

How to install MBR Filter

Installing MBR Filter is pretty simple. Go to the MBR Filter website and download the variant corresponding to your system’s architecture. Extract the contents of the zip file, and there will be two files available.

Right-click ‘MBRFilter.inf’ and select install. The installation will finish quickly and you will need to restart your computer for the changes to take place.

MBR Filter is intentionally difficult to remove so that malware cannot remove it and gain access to MBR. If you want to test if MBR Filter is working or not, you can download AccessMBR. It will read sector ‘0’ on Physical drive 0 and write that sector back checking if MBR Filter is working properly or not.

Closing Words

Make sure you install MBR Filter if you want complete protection against ransomware like Petya. If you ever want to make changes to MBR yourself, you can boot your computer to safe mode and do it.

Click here to download MBR Filter. Use this tool with caution – preferably in a testing environment first, as it comes with serious consequences.
