    De ce merge "NETUL" greu (posibile raspunsuri)

    Electronic attack slows Internet (Saturday, January 25, 2003 Posted: 8:47 AM EST (1347 GMT))

    WASHINGTON (AP) -- Traffic on the many parts of the Internet slowed dramatically for hours early Saturday, the apparent effects of a fast-spreading, virus-like infection that overwhelmed the world's digital pipelines and interfered with Web browsing and delivery of e-mail.

    Sites monitoring the health of the Internet reported significant slowdowns globally. Experts said the electronic attack bore remarkable similarities to the "Code Red" virus during the summer of 2001 which also ground traffic to a halt on much of the Internet.

    "It's not debilitating," said Howard Schmidt, President Bush's No. 2 cyber-security adviser. "Everybody seems to be getting it under control." Schmidt said the FBI's National Infrastructure Protection Center and private experts at the CERT Coordination Center were monitoring the attacks.

    The virus-like attack, which began about 12:30 a.m. EST, sought out vulnerable computers on the Internet to infect using a known flaw in popular database software from Microsoft Corp., called "SQL Server 2000." But the attacking software code was scanning for victim computers so randomly and so aggressively -- sending out thousands of probes each second -- that it overwhelmed many Internet data pipelines.

    "This is like Code Red all over again," said Marc Maiffret, an executive with eEye Digital Security, whose engineers were among the earliest to study samples of the attack software. "The sheer number of attacks is eating up so much bandwidth that normal operations can't take place."

    "The impact of this worm was huge," agreed Ben Koshy of W3 International Media Ltd., which operates thousands of Web sites from its computers in Vancouver. "It's a very significant attack."

    Koshy added that, about six hours after the attack, commercial Web sites that had been overwhelmed were starting to come back online as engineers began effectively blocking the malicious data traffic.

    "People are recovering from it," Koshy said.

    Symantec Corp., an antivirus vendor, estimated that at least 22,000 systems were affected worldwide.

    "Traffic itself seems to have leveled off a little bit, so likely only so many systems are exposed out there," said Oliver Friedrichs, senior manager with Symantec Security Response. The attacking software, technically known as a worm, was overwhelming Internet traffic-directing devices known as routers.

    "The Internet is still usable, but we're definitely receiving reports from some of our customers who have had it affect their routers specifically," Friedrichs said.

    The attack sought to take advantage of a software flaw discovered by researchers in July 2002 that permits hackers to seize control of corporate database servers. Microsoft deemed the problem "critical" and offered a free repairing patch, but it was impossible to know how many computer administrators applied the fix.

    "People need to do a better job about fixing vulnerabilities," Schmidt said.

    The latest attack was likely to revive debate within the technology industry about the need for an Internet-wide monitoring center, which the Bush administration has proposed. Some Internet industry executives and lawyers said they would raise serious civil liberties concerns if the U.S. government, not an industry consortium, operated such a powerful monitoring center.

    Smecheria cu worm-ul asta e ca odata ce a infectat un sistem trimite pachete la viteza maxima (chiar daca trimite catre adrese random) si congestioneaza legaturile. Am vazut sisteme ce generaul peste 100Mbps trafic (si umpleau legaturile fast ethernet).

    worm-ul a aparut pe 25 jan la ora 6:30 si afecteaza doar serverele microsoft sql care nu au service pack 3 (sql service pack, nu windows service pack).

    Pai tot a mers cumva. In Coreea , Taiwan si China au cazut TOATE legaturile la net pentru o buna perioada de timp.

    Thumbs down d0h

    D0h...netu' imi merge prost de pe data de 10 ianuarie (10-17 mi-a cazut netu' complet si am aflat ca a existat o "perturbare a semnalului in retea" ) De pe 17 imi merge tot mai prost...din disperare, probabil, am incercat sa sun la suport tehnic (mi-au spus ca situatia se va remedia in "cat mai scurt timp")
    Locuiesc in cartierul Militari si in ultima vreme mi-a mers MIZERABIL...CS nu mai pot juca, W3 nici atat, download-ul este de 50-60kbps (max pe metropolitana) si sa nu mai spun ca nu mai pot naviga aproape deloc (astept 2min sa se incarce pagina computergames.ro si pe site-urile din strainatate imi vine sa ma dau cu capul de pereti )
    Daca mai continua asa imi voi arde firele de par de pe cur
    Tim...poate ne poti spune daca RDS-ul are de gand sa mareasca latimea de banda
    Spune-ne te rog vesti bune...we're dying in here

    AIWA : nu stiu ce fololsesc coreenii dar cred ca s-au sucarit destul de rau avind in vedere ca penetrarea broadband e cea mai mare in Coreea ( 69% din utilizatorii casnici au net broadband de la 1.5mb/s in sus ) Isp-ul meu a fost imun la atac

    Din ziarul finaciar: "Sfârºitul sãptãmânii trecute a intrat în istoria Internetului: traficul de date din Coreea de Sud ºi Statele Unite a fost îngreunat, iar activitatea unor mari bãnci ºi companii paralizatã timp de mai multe ore. Cauza: virusul SQL Slammer care s-a rãspândit în reþelele de comunicaþii."

    ISP- ul meu : The site www.bbtec.net is running Apache on Linux.
    RDSNET : The site www.rdsnet.ro is running Apache/1.3.26 (Unix) PHP/4.2.2 mod_ssl/2.8.10 OpenSSL/0.9.6g on Linux
    Coreenii ar trebui sa se bata cu liderul de la nivelul 1 si sa treaca la nivelul urmator

    Q--> De ce merge "NETUL" greu (posibile raspunsuri)
    A--> Uneori...mai merge greu ...ca vor romanii sa ajunga pe locul 1


    Hacherii romani, la un pas de podium:
    Romania a urcat de pe locul zece, in prima jumatate a anului trecut, pe pozitia a patra, in semestrul al doilea din 2002, intr-un clasament al tarilor generatoare de atacuri pe Internet raportat la numarul de utilizatori, potrivit unui raport realizat de compania Symantec, unul dintre cei mai importanti furnizori mondiali de tehnologie destinata securitatii pe Internet. Daca Romania a generat in perioada iulie-decembrie 2002 aproximativ 21,1 atacuri la 10. 000 de utilizatori ai Internetului, cel mai ridicat numar la categoria respectiva a revenit Iranului, cu 29,3 atacuri la 10. 000 de navigatori. Kuweitul, situat pe pozitia a doua, a inregistrat cu 23,3 atacuri, Puerto Rico cu 22 de astfel de incidente, in vreme ce Letonia - ocupanta locului al cincilea, dupa Romania - a determinat 18,7 atacuri la fiecare 10. 000 de utilizatori.

    jeez... sincer sa fiu nici nu am simtit ca se misca netul greu... in afara de google care din cand in cand nu mergea...
    All parts should go together without forcing. You must remember that the parts you are reassembling were disassembled by you. Therefore, if you can't get them together again, there must be a reason. By all means, do not use a hammer. -- IBM maintenance manual, 1975
