(The Hosting News) – Web presences maintained by financial service and banking provider HSBC were knocked offline on Thursday, the company acknowledged in a press release.
HSBC emphasized no user data was affected, but noted it did disrupt a number of online services.
“We are cooperating with the relevant authorities and will cooperate with other organisations that have been similarly affected by such criminal acts,” the banking provider stated through its website.
Not all of the sites affected by the extensive downtime returned to normal availability until early Friday.
DDoS attacks are commonly uses by internet attackers, rerouting high numbers of infected systems to visit targeted websites, thus overwhelming servers that provide for the victim.
A sector of hacking collective Anonymous, Fawkes Security, claimed responsibility for the attack through a YouTube video. Another report from Fox Business, meanwhile, reported that Muslim-based hacking group Izz ad-Din al-Qassam Cyber Fighters had also taken credit.
Banking institutions have remained a common target of online attackers. Late last month, a number of notable DDoS attacks were notably launched against a variety of banking institutions including Citigroup, Bank of America, Wells Fargo and J.P. Morgan Chase.
