Microsoft Windows Zombies Also Knocked Facebook and Gawker Offline, More “Critical” Microsoft Flaws Discovered

Posted in Microsoft, Security, Windows at 9:41 am by Dr. Roy Schestowitz

Summary: More victims of Windows botnets abound; Microsoft discloses 5 new remotely-exploitable vulnerabilities

LAST NIGHT we wrote about Twitter's injury from Windows zombies. Twitter was not alone however; now that the Web is saturated with Windows botnets, anyone with an axe to grind can take Web sites of choice offline. A decade or so ago even Yahoo! was a victim, so our own suffering is very minor in comparison (but increasingly common). According to the BBC, Facebook is another new victim.

Denial-of-service (DOS) attacks take various forms but often involve a company’s servers being flooded with data in an effort to disable them.

The Register reports that Gawker too is a victim.

New York-based media news and gossip blog network Gawker is recovering from a debilitating denial of service attack.

SJVN wrote a good essay on how Twitter was killed by Windows botnets.

DDoS attacks are hard to beat. While some Twitter fans are claiming that this is the biggest DDoS attack ever, I’m inclined to doubt it. Twitter, even though its performance has gotten much better, has often teetered on the edge of collapse due to the enormous load its users put on its social network infrastructure. No, the DDoS attack on Google earlier this year was probably still the worst attack on record.

How is this happening? Well, let me tell you. Today’s DDoS attacks are made by Windows-powered botnets. They’re not terribly sophisticated about these attacks. The last major one, which may or may not have come from North Korea, was driven by MyDoom, Windows malware from 2004.

[...]

Russians already successfully attacked Estonia’s Internet infrastructure in 2007. With Windows botnets growing by leaps and bounds, it’s easier than ever for governments or even just a handful of people to knock out major Web sites like Twitter.

I’ve said it before, I’ll say it again. Thanks to Windows’ security weaknesses, botnets are now commonplace and we can only expect to see more DDoS attacks in the future.

One person believes that he knows who was behind the attack (and its motives), being the botmaster or the leader of several.

As Twitter struggled to return to normal Wednesday evening, a trickle of details suggested that the outage that left 30 million users unable to use the micro-blogging service for several hours – at least in part – may have been the result of a spam campaign that targeted a single user who vocally supports the Republic of Georgia.

Windows has become an expensive and dangerous political tool. Based on this new report from Heise, change is nowhere near.

Microsoft to patch nine security vulnerabilities on Patch Tuesday

Five of the security updates reportedly patch critical vulnerabilities that could lead to remote code execution in Windows and a variety of other software.

Here is a couple more that are new.

“It is no exaggeration to say that the national security is also implicated by the efforts of hackers to break into computing networks. Computers, including many running Windows operating systems, are used throughout the United States Department of Defense and by the armed forces of the United States in Afghanistan and elsewhere.”

  4. 2023 is the Year Taxpayers' Money Goes to War and Energy Subsidies, Not Tech

    Now that a lot of powerful and omnipresent ‘tech’ (spying and policing) companies are rotting away we have golden opportunities to bring about positive change and maybe even recruit technical people for good causes



  5. Getting Back to Productive Computer Systems Would Benefit Public Health and Not Just Boost Productivity

    “Smartphoneshame” (shaming an unhealthy culture of obsession with “apps”) would potentially bring about a better, more sociable society with fewer mental health crises and higher productivity levels

  7. Dotcom Boom and Bust, Round 2

    The age of technology giants/monopolies devouring everything or military-funded (i.e. taxpayers-subsidised) surveillance/censorship tentacles, in effect privatised eyes of the state, may be ending; the United States can barely sustain that anymore and raising the debt ceiling won't solve that (buying time isn't the solution)



  8. Society Would Benefit From a Smartphoneshame Movement

    In a society plagued by blackmail, surveillance and frivolous lawsuits it is important to reconsider the notion of “smart” phone ownership; these devices give potentially authoritarian companies and governments far too much power over people (in the EU they want to introduce new legislation that would, in effect, ban Free software if it enables true privacy)

    This year we have several 15-year anniversaries; one of them is Daily Links (it turned 15 earlier this week) and we've been working to improve these batches of links, making them a lot more extensive and somewhat better structured/clustered



  20. Back to Focusing on Unified Patent Court (UPC) Crimes and Illegal Patent Agenda, Including the EPO's

    The EPO's (European Patent Office, Europe's second-largest institution) violations of constitutions, laws and so on merit more coverage, seeing that what's left of the "media" not only fails to cover scandalous things but is actively cheering for criminals (in exchange for money)



  21. European Patent Office Staff Votes in Favour of Freedom of Association (97% of Voters in Support)

    The Central Staff Committee (CSC) at the EPO makes a strong case for António Campinos to stop breaking and law and actually start obeying court orders (he’s no better than Benoît Battistelli and he uses worse language already)

  29. Intimidation Against Nitrux Development Team Upsets the Community and Makes the Media Less Trustworthy

    Nitrux is being criticised for being “very unappealing”; but a look behind the scenes reveals an angry reviewer (habitual mouthpiece of the Linux Foundation and Linux foes) trying to intimidate Nitrux developers, who are unpaid volunteers rather than “corporate” developers
