Crypter overview
by cipher- 6 replies
- 12.5k views
hello i am here today with the executable that can obfuscate the virus and makes it fully undetectable from anti-viruses.This executable uses runPE techniques to inject into other process and to dump the crypted code into memory and hence the executable's code remain undetected by Anti-viruses. These crypters are programmed by individuals and hence remains undetected most of the time .Mostly they are coded in VB or .Net and hence you will find most of the viruses showing vb attributes during PE Scans ,but mostly the viruses/RATs/Stealers/Bots/Worms are coded in borland Delphi. Examples : 1) RATS : cybergate,Blackshades,pixel,spynet,darkcomet etc 2) STEALERS …

Hey there, I managed to get a sample of a "Ransomware" type of virus, which just locked the computer until one paid and got puts in a code to unlock (which I doubt would actually unlock it) Anyhow, I grabbed the virus.exe and it's getting detected by 22/40 AV's. I looked at it witrh PEiD which couldn't find anything, I assume the file is most likely packed. I also ran a string command on it, nothing came out (except assembly XML file, so even more chance it's packed) Then I disassembled the with IDA (all this in linux since it's risky :3 ) Here is a list of the imports: 10004000 RegOpenKeyExW ADVAPI32 10004008 GetSaveFileNameW …

Just as Oracle is ramping up for the September 30 start of JavaOne 2012 in San Francisco, researchers from the Polish firm Security Explorations disclosed yet another critical Java vulnerability that might “spoil the taste of Larry Ellison's morning…Java.” If you disabled Java when the last zero-day exploit was spotted in the wild, then you might consider doing so again . . . or dumping Java altogether? According to Security Explorations researcher Adam Gowdiak, who sent the email to the Full Disclosure Seclist, this Java exploit affects “one billion users of Oracle Java SE software.” Appalled to learn that Oracle/Java has another huge critical hole, I reached out to Adam…

All network traffic sniffer
by R4ndom- 5 replies
- 6.6k views
I think I may have a rootkit or keylogger on my other computer and I'm wondering if someone can recommend a good program to see ALL data that leaves your computer over a wired network, sort of like what wireshark does for wifi. It doesn't need to be complicated, just something that shows me every bit that goes over the wire so I can see if there is suspicious data flowing from my computer. I tried running the rootkit detection software out there but it doesn't work very well for 64-bit windows. Thanks for you help.

Malware/Java Issue
by cozofdeath- 8 replies
- 6.7k views
I've been running my computer just fine with no problems for as long as I can remember. Any type of malware seems to get eliminated right away if found. However, whenever I see the small java icon in the sys tray popup I know an exploit it being executed and usually my AV will pop up and eliminate the threat. Yes, I know java isn't bad but the only time I see it executing it seems to be. The other day this same thing happened but it managed to get through and instantly shut the computer down and cause many other problems. My question is, why is it always java doing this? Yes, I know what java is, for the most part, and no I wasn't looking at porn when it happened. These j…
