Malwarebytes will actually cull their signature database for malware that is no longer seen in-the-wild Today. That means that something like the BugBear which infected years ago will not be targeted by MBAM. Malware that is infecting computers Today with malware found in-the-wild, Today. That means it will not target old malware. MBAM is not a historical anti malware solution. Those numerous modifications to the Operating System is where the traditional anti virus application does poorly and where MBAM specializes. Today's malware is very intrusive and makes numerous modifications to the Operating System. To effect that the malicious actors don't want the victim to know that their system was compromised or they are so blatant about it by generating advertisements, Yesterday's malware was simple and less obtrusive. Either by stealing, distribution affiliation revenue, data exfiltration, personal identification impersonation, etc. Malicious actors use malware to profit from. Today's malware is more sophisticated in that it is "all about the money". When we saw the Melissa virus ( I-Worm via SMTP ), Lovsan/Blaster worm ( I-Worm via RPC/RPCSS TCP port 135 ) etc, they were distributed for the effect, damage and bragging rights. Today's malware is much more complex than 10 years ago. Where a traditional anti virus application is weak, MBAM is strong. Since MBAM can not remove the added malicious code, at best MBAM will try to replace the trojanized file with a legitimate, unaltered, file. These files are either deemed to be "trojanized" or "patched". The infection stops with that targeted file. However that file can not infect other files. On the other hand there are trojans that will prepend, append or cavity inject malicious code into a legitimate file. Once infected, that infected file can further the infection by infecting other legitimate files. Which may or may not return the file to its original, non infected, checksum value.Ī file infecting virus will prepend, append or cavity inject malicious code into a legitimate file. An anti virus application should be able to remove malicious code from an infected file and hopefully bring it back to its preinfected state. That means if a file infecting virus infects a legitimate file MBAM will be unable to remove the malicious code. MBAM is incapable of removing malicious code that has been prepended, appended or cavity injected into a legitimate file. The exception being a virus dropper ( a malware file that drops a virus and starts a virus infection but is not infected with the virus ) and worms ( such as Internet worms and AutoRun worms ). Any of these files types can be renamed to be anything such as TXT, JPG, CMD and BAT and they will still be targeted just as long as the binary starts with ' MZ'. They can be EXE, CPL, SYS, DLL, SCR and OCX. MBAM specifically targets binaries that start with the first two characters being MZ And self-Extracting ZIP, 7z, RAR and NSIS executables (aka SFX files). MBAM v1.75 specifically will deal with ZIP, RAR, 7z, CAB and MSI for archives. Same goes with CHM files (which is a PKZip file) but it doesn't target the HTML files within. Until MBAM, v1.75, MBAM could not access files in archives but with v1.75 came that ability so it can unarchive a Java Jar (which is a PKZip file) but it won't target the. It also does not target media files MP3, WMV, JPG, GIF, etc. It also does not target document files such as PDF, DOC, DOCx, DOCm, XLS, XLSx, PPT, PPS, ODF, RTF, etc. CLASS, SWF, SQL, BAT, CMD, PDF, PHP, WSF, etc. That means MBAM will not target JS, JSE, PY. In its role as a adjunct, complimentary, anti malware application it has limitations in aspects that the anti virus application ( in this case, NAV ) performs in its role. MBAM is an adjunct, complimentary, anti malware application. MBAM is not an anti virus application and does not replace an an anti virus application. malware referred to as "Zero Day" malware. Well, it won't be detected by MBAM 'cause it is too old. However he did post a Virus Total Report URL.įrom that Report, we see First submission 07:14:10 UTC ( 2 years, 1 month ago ) The so-called tester is not an authorative source and the testing is not described.
