6 ianuarie 2006 - Atentie la viermele Sober

Microsoft a emis un Advisory: Microsoft Security Advisory (912920)

Sistemele infectate cu Win32/[email protected] aka Sober.Y, WORM_SOBER.AG, W32/Sober-{X, Z}, Win32.Sober.W, W32/[email protected]!M681, W32/[email protected], pot face download si executa fisiere malitioase de pe anumite domenii web, incepand cu 6 ianuarie.

Algoritmul folosit de vierme pentru a genera URL-uri a fost descoperit anul trecut de F-Secure:
Sober worm algorithm cracked by F-Secure

Solutii:
Scanati sistemul cu un AntiVirus online:
F-Secure Online Scanner
TrendMicro Online Scanner
Panda Active Scan
Kaspersky Online Scanner
MS Windows Live Safety Center

Nu deschideti atasamente email fara sa le scanati cu un AntiVirus si nu deschideti atasamente de la necunoscuti.

Nu faceti click pe linkuri in instant messenger.

Detalii despre Sober:
[email protected]
Sober.Y

Ultima raspandire de amploare a viermelui a fost in noiembrie 2005.

Acest vierme foloseste ingineria sociala ca sa se raspandeasca. Mesajul dintr-un email incearca sa te convinga sa deschizi un atasament (ZIP) si sa executi fisierul continut.

Nu uitati ! Maine, marti 10 ianuarie 2006 = Black Tuesday.

Vizitati Windows Update spre seara ca sa instalati patch-urile. Nu ezitati sa faceti download la Microsoft Windows Malicious Software Removal Tool ca sa-l omorati pe Sober daca e prezent.

Romania in FBI Report

FBI says attacks succeeding despite security investments

Quote

Despite investing in a variety of security technologies, enterprises continue to suffer network attacks at the hands of malware writers and inside operatives, according to an annual FBI report released today. Many security incidents continue to go unreported.

Quote

Of the intrusion attempts coming from outside the organizations, the most common countries of origin included the United States, China, Nigeria, Germany, Russia and Romania.

Quote

An example of this type of stepping-stone attack would be a Romanian hacker that uses a proxy computer in China to access a compromised computer in the United States, the report said. This U.S.-based computer would then be used to perform the computer intrusion. Those investigating the incident may falsely conclude that the source was within the United States.

Mark Russinovich vede rootkituri peste tot  :lol:

Symantec, Kaspersky Criticized for Cloaking Software

Dar Kaspersky nu foloseste vreo tehnica rootkit, iar tehnologia iStreams™ de la Kaspersky nu are cum sa fie exploatata de malware.
Explicatii aici: No rootkit in Kaspersky Anti-Virus

Pentru cunoscatori doar

Internet Explorer 7 Beta 2 Preview

Deocamdata numai pentru Windows® XP Service Pack 2 (SP2).

Microsoft said:

The software should not be used on production systems in mission-critical environments. Internet Explorer 7 Beta 2 Preview will only run on Windows® XP Service Pack 2 (SP2) systems, but will ultimately be available for Windows Vista, Windows XP Professional x64 Edition, and Windows Server 2003.

Win32/[email protected] aka Blackmal, Nyxem, Grew

In Romania sunt probabil in jur de 500 infectii cu acest vierme.

Merita sa scanati computerul (inainte de a ramane fara documente).
Kaspersky Online Scanner: http://www.kaspersky.com/virusscanner
F-Secure: http://support.f-sec.../home/ols.shtml
Bit-Defender: http://www.bitdefend...can/licence.php

MS a mai trimis azi un "Security Advisory Notification" in legatura cu Mywife:
Microsoft Security Advisory (904420)

Viermele suprascrie toate fisierele cu extensiile:
*.doc
*.xls
*.mdb
*.mde
*.ppt
*.pps
*.zip
*.rar
*.pdf
*.psd
*.dmp
si continutul nu mai poate fi recuparat.

Pe data de 3 a fiecarei luni (daca data e setata corect la calculator), la 30 de minute dupa ce PC-ul a fost pornit viermele intra in actiune.

Nu exista un asemenea virus, e o prostie, un asa numit "hoax" care circula pe internet. O alarma falsa care alerteaza inutil utilizatorii. McAfee confirma ca e un hoax desi e semnalat mai demult http://us.mcafee.com...n&virus_k=98893.La fel si sophos http://www.sophos.co...irtualcard.html

Exploit public - Firefox 1.5.0.

Daca nu ati facut update inca, nu ezitati. Pana cand cineva sa exploateze vulnerabilitate in the wild nu mai e  mult.

Download Mozilla FireFox 1.5.0.1.

Firefox 1.0.7. are si el mai multe vulnerabilitati.
Este posibil sa urmeze un update: 1.0.8.
FF 1.5.0.1. poate fi o optiune si in cazul asta.

Chirurgia endoscopică a hipofizei Chirurgia endoscopică a hipofizei

"Standardul de aur" în chirurgia hipofizară îl reprezintă endoscopia transnazală transsfenoidală.

Echipa NeuroHope este antrenată în unul din cele mai mari centre de chirurgie a hipofizei din Europa, Spitalul Foch din Paris, centrul în care a fost introdus pentru prima dată endoscopul în chirurgia transnazală a hipofizei, de către neurochirurgul francez Guiot. Pe lângă tumorile cu origine hipofizară, prin tehnicile endoscopice transnazale pot fi abordate numeroase alte patologii neurochirurgicale.
