How severe can the impact of the Conficker worm be on a single city council that has apparently not implemented basic security solutions in place?

Pretty severe according to a recently released a report entitled “Service interruption resulting from ICT disruption in February 2009” which details the financial costs of a Conficker incident affecting Manchester City Council’s network - 1.5 million pounds in clean up costs and lost revenue from the downtime.

Where did all the money go, and can this incident cost be used as an average to draw conclusions from in the long term in respect to assessing Conficker’s financial impact on affected networks? Let’s find out.

The sudden death of Michael Jackson quickly opened a window of opportunity for cybercriminals to capitalize on.

With a malicious spam campaign, blackhat SEO search results poisoning which is serving scareware within the first 100 search results for Michael Jackson’s death, and an opportunistic participant in Zango adware’s network using typosquatting, malicious activity is prone to increase during the next couple of days.

Here are more details on the campaigns currently in circulation:

With the time frame for an exploit to become an inseparable part of a web malware exploitation kit shrinking, and with the average Internet user’s over-confidence in an antivirus scanner’s ability to detect and block exploits (Secunia: popular security suites failing to block exploits) it shouldn’t come as a surprise that Secunia’s recently released WorldMap shows a relatively high rate for insecure programs found on a single PC.

The WorldMap of patched and unpatched PCs is released prior to an updated version of Secunia’s Personal Software Inspector, with the latest version finally filling a niche left open potentially undermining the usefulness of the handy tool in general - measuring the exploitability of cross-browser plugins such as Adobe Flash Player, QuickTime, or Sun’s Java.

Let’s take a look at some of their stats.

The project, called Content Security Policy, is designed to shut down XSS attacks by providing a mechanism for sites to explicitly tell the browser which content is legitimate. It can also help mitigate clickjacking and packet sniffing attacks.

Researchers from Computer Associates (NASDAQ:CA) and Sophos are reporting on three currently active malware campaigns using fake Microsoft patch themes as a social engineering tactic to spread over email.

The first one is spreading as an “Important Windows XP/Vista Security Update” and is offering a bogus Conficker removal tool, the second is using an “Outlook re-configuration” — also spammed earlier this month — and the third one is using an out-of-the-band “Update for Microsoft Outlook / Outlook Express (KB910721)” theme, which in reality is nothing else but a trojan.
