Gameover ZeuS Re-Emerges As Fast-Fluxing Botnet
New submitter tylke (621801) writes: "Brian Krebs is reporting that the Gameover ZeuS botnet recently taken down by the U.S. Justice Department in June has re-emerged. The new variant of the Trojan is "stripped of the P2P code, and relies instead on an approach known as fast-flux hosting," a kind of round-robin technique that lets botnets hide phishing and malware delivery sites behind a network of compromised systems. Krebs says, "[T]his variant also includes a 'domain name generation algorithm' or DGA, which is a failsafe mechanism that can be invoked if the botnet’s normal communications system fails. The DGA creates a constantly-changing list of domain names each week (gibberish domains that are essentially long jumbles of letters).
In the event that systems infected with the malware can’t reach the fast-flux servers for new updates, the code instructs the botted systems to seek out active domains from the list specified in the DGA. All the botmasters need to do in this case to regain control over his crime machine is register just one of those domains and place the update instructions there." (Disclosure: I work for Malcovery Security, the company credited with identifying the new variant.)
'fast fluxing' is the result of zombiefied router storms gone rouge.
The article from Brian Krebs seems to indicate that this new variant of Gameover can interface with the old one somehow, and be used to recover all of the infected computers that were part of the original Gameover botnet. Is this true, or is this an attempt to re-build the Gameover Zeus botnet from scratch?
How the hell can you just register a billion different randomized domain names without attracting attention or incurring any cost?
The article linked to Wikipedia on what Fast Flux was:
The basic idea behind Fast flux is to have numerous IP addresses associated with a single fully qualified domain name, where the IP addresses are swapped in and out with extremely high frequency, through changing DNS records.
In case anyone else didn't know that was Fast flux was.
I stopped paying attention to botnet stories a few years ago. Are botnets still always on Windows or do Unix users (Mac, Linux) have to worry too? If it's still all Windows then I'm going to stop paying attention again.
all 42 horcruxes
Discovered it?, or wrote it? It's easier to write this trash than to disassemble it.
Malcovery says that if the .scr is run within a VM, it fails to operate - that suggests that using a VM obtains a measure of safety.
Presumably, not operating within a VM makes it harder to figure out how it operates, but it makes it easy to make a system immune.
Fast-flux or not, registering one of those domain names would put a target on your back. Reinforce your doors before you try it.
This botnet, like the one the malware based on, is Windows only. The botnet that was used to seed this one is also Windows only.
There have been two botnets that kinda-sorta might be interesting to Linux and Mac users. In one, if you used a Windows desktop to ssh to a Linux server, the infected Windows machine could reveal the user name and password that you used from Windows. In the other, some idiots left the default admin user name and passwords on their routers, some of which run Linux. Surprisingly, if the bad guy knows your username and password, that's a bad thing no matter what operating system you use.
> suggests that using a VM obtains a measure of safety.
You can make it almost perfectly secure by mounting Documents from another disk or image and marking the operating system VM read-only, or snapshotted so it reverts state on reboot.
Toggle it read-write while you update the OS or install new software.
Suppose you have nastyshit.exe in your documents folder. How is it going to get executed? At boot, by a registry entry? Nope, because all the boot stuff, including the registry, is read-only. How did it get there in the first place? Not from malware resident on the system, because the system is read-only.

That does the job against fastflux botnets != spam. You're an off topic troll that's most likely a botnet master.
You are a jealous trolling big piece of shit that wishes he was apk.
Open SORES idiots spam Adblock here nonstop for years. Adblock is inferior hosts on many levels. Your point is what here? Go away trolling scum.

What "experts"? Like Wladimir Palant of "Almost ALL Ads Blocked"?? He wrote me, 1st mind you, stating "hosts are a shitty solution" - I wrote back:
"Show us AdBlock can do MORE than hosts files do in terms of security, speed, reliability, & anonymity, & that they can do all that, MORE EFFICIENTLY than hosts"
LMAO - he RAN like a scared rabbit!
I did so, from 2 diff. email accounts in reply to his weak bullshit... he ran, & THAT, is that.
A big name PhD & former "co-worker" of mine a decade ago when I took him down a peg in Microsoft's Dr. Mark Russinovich on Memory Optimization tech unfreezing & speeding up Exchange Servers no less with MS' OWN DOCUMENTATION no less!

Even MORE recently (but this guy I admire even though his tech in reactive antivirus' is dying vs. webbound threats, when hosts do NOT) in Aryeh Goretsky of ESET/Nod32 won't take the challenge I put his way here -> http://it.slashdot.org/comment...
Symantec/Norton, McAfee/Intel, ClamAV, Comodo, & ArcaVir made mistakes calling APK Hosts File Engine a "virus" & I told them where they f'd up!

His program works perfectly against the threat in Zeusbot. It's on topic, you're not, troll http://it.slashdot.org/comment... and you're just jealous and wish you were apk, or you are a botnet master, inferior competitor, advertiser, or webmaster who loses views since his app gets you speed and security back against banner ads (good and malicious code infected ones) and reliability against downed or dns poisoning redirected dns servers, and even anonymity against dnsbl or dns request logs. Have you done better? Have you proven apk's points wrong? No to both. You're just a trolling whimp.

Unlike your lazy big talk do zero ass, I actually got off my ASS & did something about it!

Funny how I pointed out that ANDROID (a Linux) is being dismanted & destroyed, abused daily (stupidly using a Java/Dalvik front-end user interface too) - which dismantles & DESTROYS you, + your b.s. quoted above, easily... apk
Read here - PERTINENT QUOTE right off the bat = "Android is a mobile operating system (OS) based on the Linux kernel that is currently developed by Google" -> http://en.wikipedia.org/wiki/A...
* That ALONE, says it all...
When an OS uses a Linux kernel, it IS a Linux... & yes, "noobz" use it on phones, big time (& it's being TORN UP DAILY with exploits, in part largely to what I noted too - using Java/Dalvik as a front end, AND additionally have C code (to *try* make up for performance, when C++ would've been a BETTER choice, no questions asked)... however, even C++ & OOP can't protect you vs driver based exploits (ala rootkits).
(You fail!)
APK
P.S.=> Quit projecting little noob chump - you will NEVER, ever, in your entire LIFE be even CLOSE to the class of pc knowledgeable I am - accept it (the above proves it vs. your bullshit, easily)... apk
Face facts: You fail! Android uses a Linux core thus, as wikipedia notes - It IS a Linux - period.
APK
P.S.=> Despite your other added b.s. also? Yes, SOME Linux users ARE NOOBZ, & Android being a Linux, proves it (on smartphones, where it is being "torn up" by exploits, daily)
&
That also proves another point of mine I've long said here that would BITE THE LINUX & Open "Sores" b.s artists here, in that the MORE any OS is used, & especially if it ends up as KING of the particular hardware platform it rides on (Which Android/Linux is on smartphones, like Windows is on PC's & Servers combined) THE MORE IT WILL BE ATTACKED...
History's proven me correct on that statement too, yet again (I saw it before that on DOS) as well as CRIMINAL "human nature" in that they want the most "bang for the buck" from a SINGLE codebase, that can attack the most potential possible victims (which you *may* have to "channel your 'inner criminal'" to understand)
Here? Yes - I see it everyday since I work with the security community nearly daily, & via this program I wrote for them + anyone that chooses to use it to get the benefits of added speed, security, reliability, & even anonymity it yields, more efficiently than ANY browser addon level slower inferior competitor, as well as shoring up DNS redirect security issues as well (bonus) -> http://start64.com/index.php?o... )
