Massive Botnet Returns From the Dead To Spam On

CWmike writes "Gregg Keizer reports that the big spam-spewing Srizbi botnet, shut down two weeks ago when McColo was shuttered, has been resurrected and is again under the control of criminals, security researchers said today. As of late Tuesday, infected PCs were able to successfully reconnect with new command-and-control servers, which are now based in Estonia, said Fengmin Gong, chief security content officer at FireEye. The comeback confirms what researchers noted last week, that Srizbi had a fallback strategy. So, in the end, that strategy paid off for the criminals who control the botnet."

      Why would botnet harvesting be done by domain name anyways? Wouldn't it be easier to collect systems by just running through accessible IP addresses?

      And if the botnets are doing double duty by both propagating spam and attempting to hack into systems via ssh, I can tell you from my IP logs at home that most systems in the botnets aren't behind any particular domains.

      Actually there isn't money to be made this way because all those unhappy customers demanding refunds will be expensive. The idea that you can clean an infected Windows PC by installing product A or B or C is mistaken. The whole idea that security is a boxed product or is available by clicking an .exe/.msi installer is bogus. Assuming that the malware on these infected computers is even known to the AV companies (and that's no longer a reasonable assumption in most cases) then the only way to actually remove it effectively is by running the AV tools from read only media, i.e. a live CD. Well designed malware will simply disallow the installation/use/updating of common AV software. The malware authors are streets ahead of the "security" vendors. The AV products installed on a clean machine can't even prevent many of these problems let alone cure them. Most Windows users would be better advised to save their pennies and re-install from original media, always be patched and up to date (applications as well as OS), run as unprivileged user with strong passwords on all accounts and browse only with Firefox + privoxy + noscript + adblock. That isn't perfect but it's zero financial cost and way more effective than anything Symantec, McAfee etc can offer. Unfortunately running Windows with an unprivileged account is as convenient as toothache.

      There's a lot more to it than launching applications. Even then it's unsatisfactory in many ways. It's extremely inconvenient to have to run an application as admin and have all the output non-executable and non-writable for other users...one more crappy task to fix all the permissions after every run. Anyway there are many applications which simply don't work with run as. The previous poster who linked to Super SU was nearer the mark. Windows user model works fine for users with no local admin rights working under a domain controller, i.e. in the office with IT dept running everything. For home/individual users it really stinks. The existence of botnets of tens or hundreds of thousands of compromised Windows PCs should negate the need to even mention or discuss this but it seems that simple, sane authorisation models have been thoroughly subverted for so long that the absolute worst model is considered normal and acceptable. What's really incredible to me is that if you look at unix user/super user model or the Ubuntu/OS X style sudo model they are both easy and *convenient* for the end user as well as the administrator and have no real drawback; I can't quite work out why MS dedicated the last 10 years to screwing it up so badly. It is a horrible experience for their users to suffer unwanted malicious software on their systems and it could all have been easily avoided. It shouldn't be normal to run a system so badly configured and implemented that it requires 3rd party add ons simply to appear secure. It shouldn't be anything other than extraordinarily unusual to have one's personal and financial details exposed to criminals etc. Run as is not the answer because there are too many situations where it simply doesn't work or is so inconvenient that it becomes impractical. Personally speaking, Windows is only for games while everything else gets done on a sensible OS. Windows by default has no immunity and no powers of recovery. It has AIDS.
