Re: Malware Warning

Yet another reminder to choose a more secure OS.

Opps, yes it is.

Re: Malware Warning--Again!!!

It seems that SailNet has been reinfected. I attempted to connect this AM and our system went bonkers. The follwoing is the Avast blocking message:

Quote:
Infection Details

URL:javascript:false;Process:file://C:\Program Files\Internet Explore...Infection:html:Iframe-inf
Warn your friends to avoid this website
Other messages followed in quick succession as I attempted to maneuver away from the site without shutting down our system which I finally did.

Re: Malware Warning

there are signs of US Gov internal data gathering in USA's current political cyber state paranoia so info security should not be forgotten.

Unfortunately, I really don't know enough about the workings of these systems to know whether the machine is really clean or not. I must say that I long ago disabled "Automatic Updates" on as many files as possible as I found most up-dates caused more problems than they solved. The fastest and least problem-some computer we have is a Laptop that does not speak to the internet at all. (Frankly, to me a computer is nothing more than an adding machine with a bad attitude.)

Now. The question is--who's going to venture over to SailNet to determine when if their site has been disinfected? (Not Moi!)
If malicious payload has been placed in your user profile (desktop), your machine's security has been compromised.

Deactivating automatic installation of operating system updates is unwise, and the longer a machine is deprived of security patches, the more vulnerable it becomes.

"Updates cause more problems than they solve" is simply not true. Tens of millions of computers worldwide run modern general-purpose software, and automatic security updates are appropriate for all except a vanishingly small percentage of special-purpose systems. It is a bad idea to fall prey to the loud opinions of conspiracists and self-declared experts who claim to know more than the teams of professionals who create and maintain operating systems.

Following three straightforward principles will protect against the vast majority of threats:

1) Religiously apply all official operating system updates.
2) Select an anti-malware suite from a reputable vendor, and ensure it too is receiving regular updates.
3) Use a low-powered non-administrator account 99% of the time, except when deliberately intending to make operating system configuration changes.

Not true. There is a vast difference between executable code and the content of a photo. Content misrepresentation attacks are decades old, and modern OSs are highly resistant to the kind of simplistic trickery you describe.

To prove it to yourself, make a copy of C:\Windows\Notepad.exe, rename it to JustAPhoto.JPG, and then double-click the file.

Nah, browsers too are highly resistant to that type of simplistic attack, and they will not run downloaded compiled code, just because it is lurking in an HTML file.

The vast majority of AV software relies on real-time scanning of executables for patterns corresponding to malware _before_ the executable is allowed to run. If something suspicious is detected, the AV will seek to prevent execution. That is called static analysis. Suspect code is analysed by looking at it in dormant form.

"Checking to see what happens after the code executes" is called dynamic analysis, and it is very rare. It entails a sandbox environment where potential damage is contained, significant hardware horsepower to generate detailed before-and-after comparisons, and automated or manual smarts to gauge whether or not the effect is actually malicious. Dynamic analysis is the domain of security researchers, specialised hardware appliances used by very large companies, and AV software vendors themselves. Home and small-office PCs are not doing dynamic analysis.

Terrible advice.

The moment an update is released by Microsoft/Apple/Google, everyone ranging from state-level actors to naughty 14 year olds start disassembling it in the hope of understanding the nature of the vulnerability which is addressed by that update. Within hours, sophisticated attackers typically understand the defect, and perhaps how to exploit it, even if they had no idea that a vulnerability existed in that area before the update was released.

Those who deactivate automatic updates, and go out of their way to keep their machine behind the times, even though it is connected to the public Internet, are thus "just asking for it", to use a highly technical phrase

There is no such feature in Windows.
