#### With regards to the above matter, MyCERT had received reports of mass web defacements involving organisations in Malaysia over the week-end, with 22 .MY websites were defaced. About 98% of the web defacements involved websites running on Linux machines.
MyCERT observed that hacker groups believed to be from overseas is actively involved in the mass web defacements.
Based on MyCERT's analysis, one of the hacker groups had also been actively involved in the previous mass defacements of Malaysian websites in March 2005 and both groups are also actively involved in defacing Danish websites.
Though the number of defaced sites is not alarming, MyCERT's concern is if the number increases over the time. Thus, MyCERT would like to urge all System Administrators and owners of websites to upgrade and patch software/services/applications they are currently running on. In addition, it is also recommended to disable unnecessary/unneeded default services supplied by vendors. MyCERT encourages system administrators to consult MyCERT for further advises and assistance, if they have difficulties in proper securing and hardening of their servers.
