Phishing attack on popular German bank

Last week, the CYREN team detected a massive phishing attack on customers of the German bank Postbank, with more than 50,000 new phishing URLs detected within the first 24 hours. Phishing emails are traditionally sent to a massive group of people, in the hope that among the recipients are actual customers of the brand and within that group there are unsuspecting users that will click the phishing link and complete whatever information request is included. In this case the email and phishing site look very similar to the legitimate Postbank website and so it is hard for regular users to see that this is actually phishing scam and unfortunately, enough people will fall victim to the scammer’s attempts.

“The Cyber-Grinch and Cyber-Scrooge hated Christmas!

The whole Christmas season!

Now, please don't ask why. No one quite knows the reason.

It could be their monitors weren't screwed on just right.

It could be, perhaps, that their USB ports were too tight.

But I think that the most likely reason of all,

May have been that their hard drives were two sizes too small.”

Tis the season for laughter, cheer, mulled wine, and carols sung with kindly Old Fezziwig’s ghost smiling down upon your merry band of friends and family. And it is also time for the annual Christmas scam.
