Week In Security: Klez.H Takes Top Spot, Exchange 2000 Flaw

 Message Labs, a managed e-mail security provider, said it expects the mass-mailing Klez.H to become the biggest virus ever, surpassing SirCam. The company said it tracked 700,000 copies of Klez.H, which surfaced in April. MessageLabs attributed the worm's success to its ability to change its appearance, with varying subject lines and messages, making it harder to detect. The company said it logs more than 20,000 copies of Klez.H daily.
