Denial of Service attacks against financial companies increased threefold in the first quarter of 2012 compared to the fourth quarter of last year, according to Prolexic Technologies, a provider of Distributed Denial of Service (DDoS) protection services.
According to a study the firm carried out, 5.7 quadrillion bits of data and 1.1 trillion malicious packets were identified in the first quarter of this year, representing a 3,000% increase in malicious packet traffic over Q4 2011, Prolexic reported.
There was also a 25% increase in total number of DDoS attacks over the last quarter of 2011, and a 25% increase in Layer 7 (application layer) attacks, the vendor said. China remains the top source country for attacks but the U.S. and Russia both moved up in the rankings.
Infrastructure layer attacks targeting Layer 3 and Layer 4 continued to be the choice of attackers, although this quarter showed a 6% increase in DDoS attacks targeting the application layer (Layer 7).
