Claim
The first variant of Conficker, discovered in early November 2008,
Correction

Microsoft's own malware documentation dates Conficker.A to November 21, 2008, not early November.

Full reasoning

Microsoft’s published Conficker threat documentation gives Worm:Win32/Conficker.A a "Discovered date" of 21 November 2008. Microsoft’s Security Intelligence Report for July–December 2008 likewise says "On November 21, 2008, the first significant worm that exploits MS08-067 was discovered and designated Win32/Conficker."

Because Microsoft’s own contemporaneous sources place the first Conficker discovery on November 21, 2008, the article’s wording that it was discovered in "early November 2008" is incorrect.

Claim
On 13 February 2009, Microsoft offered a $USD250,000 reward
Correction

Microsoft announced the Conficker reward on February 12, 2009, not February 13.

Full reasoning

Microsoft’s own press release announcing the Conficker response effort is dated February 12, 2009 and states that Microsoft "also announced a $250,000 reward" for information leading to the arrest and conviction of those responsible. Microsoft’s MSRC blog post about the same announcement is also dated February 12, 2009.

So the encyclopedia entry is off by a day here: the reward was announced on February 12, 2009, not February 13.
