Dangerous Trojan attacks Yahoo Mail and Hotmail

A new threat is affecting Yahoo Mail and Hotmail, two of the biggest email sites on the Internet. BitDefender Antivirus Labs identified that threat as Trojan Spammer.

Security firm HotLan.A said the Trojan sought to use email accounts to send millions of spam.

However, its operation is quite complicated because it automatically creates new email accounts and uses email addresses found on many websites, then sends spam to all emails. this.

The head of BitDefender Antivirus Lab, Viorel Canja, commented: ' There are about 500 new accounts created every hour. But so far we have discovered more than 15,000 Hotmail accounts of abuse. It's hard to estimate the amount of spam sent every day . '

E-mail service is always the "target" of dangerous Trojans.

The most bizarre thing about this incident is the way that Trojan horse creates mail addresses even though both Yahoo and Hotmail services are protected by visual captchas technology (visual validation image).

These security tools require users to log in the password displayed in the form of images, so creating a script that can bypass this protection barrier is not easy.

If an intruder has the ability to build a software solution that can overcome visual captchas, it is clear that our computer is under threat without any means of defense. However, users are advised to use complex passwords and avoid opening unsolicited messages sent to your inbox.

In addition, you can use an effective anti-spam program to protect your account as well as avoid publishing email addresses to public websites because intruders can use it for spam purpose.

According to recent reports, your email address will not be suspended as Yahoo Mail and Hotmail are rapidly closing dangerous email addresses to prevent spam.
