Microsoft has fallen victim to another hacking attack by the Syrian Electronic Army
A Microsoft blog has been hacked by the Syrian Electronic Army shortly after two of its Twitter accounts and another blog were attacked by the same group.
The Office blog had just been redesigned before it was targeted by the hackers who posted a screenshot of their work on their Twitter feed.
Pervious attacks were used to post pro-Syrian government messages and criticisms of the firm.
Microsoft has not yet commented on the latest attack.
The Syrian Electronic Army had warned Microsoft that there may be more attacks
Several articles appeared on Microsoft’s site with the title, "Hacked by the Syrian Electronic Army", before being removed, reported tech news site The Verge.
After the attack the SEA addressed a tweet to Microsoft which said: "Changing the [content management system] will not help if your employees are hacked and they don’t know about it."
The group had previously used Twitter to warn the company that more attacks may happen after some of Microsoft’s social media sites were compromised earlier in the year.
It said: "We didn’t finish our attack on @Microsoft yet, stay tuned for more."
After that incident the company shut down its affected accounts for "maintenance".
In a statement issued at the time it said "no customer information had been compromised".
"What the SEA does is not very sophisticated. But it works and people need to be much more vigilant," said security analyst Graham Cluley.
"This is embarrassing for Microsoft but will it mean people won’t buy Microsoft software? Probably not."
The company also confirmed that at the time of the earlier attack a small number of employee email accounts had been accessed by the SEA.
Screenshots of conversations between Microsoft executives were tweeted by the group.
Microsoft said that the accounts had been "reset".
What is the difference between CMOS & BIOS?
CMOS is a type of memory chip that stores the BIOS information. The terms often are used interchangeably
CMOS stands for Complementary Metal Oxide Semiconductor and is pronounced "sea moss." It describes the material out of which the chip is made. A CMOS chip will store information as long as it receives power that is usually supplied by a battery
The BIOS is the Basic Input Output System. On startup, the BIOS tests the system and prepares the computer for operation by searching for system components and configuring memory to access the system hardware. It then loads the operating system and passes control to it
The BIOS can be configured with information about system components in the Setup screen that can be accessed during bootup. Usually the F1, F2, DEL keys are used to access the BIOS Setup. Click here for more key commands.
Because the BIOS is stored on a CMOS chip the Setup is also referred to the CMOS Setup
