Managed services provider warns of increasing e-mail attacks

Secure managed messaging services firm FrontBridge Technologies has recorded record numbers for spam and viruses in May

Secure managed messaging services firm FrontBridge Technologies has recorded record numbers for spam and viruses in May.

The company noted that in excess of 7.2 billion messages were transmitted across its network, blocking more than 85% as spam and rejecting more than 319 million virus-laden emails. Peak spam levels in May exceeded 95% three times.

Despite May’s record high message volume totals, FrontBridge customers were protected from the onslaught that brought down email operations for companies relying on non-scalable appliances. 

FrontBridge normally processes on average more than five billion business email messages a month for more than 3,700 companies. On 5 May, FrontBridge noted more than 180 companies on its network experiencing triple digit increases in message volume over the previous week. Seven customers experienced quadruple digit message increases, with one company seeing message volume increase by an unprecedented 4,287%.

FrontBridge states that these wild variances in traffic volumes would have crippled appliance-based systems which cannot scale to handle swings in data flow. “FrontBridge is tracking an army of spambots across the world that now includes millions of machines, replenishing a pool that had been on the decline for months,” comments Charles McColgan, chief technology officer, FrontBridge Technologies.

“The SOBER epidemic really underscores the importance of outsourced services for protecting against threats. On-premise software and appliances are ill-equipped to deal with wild fluctuations in message volume and expose companies to significant risk when systems crash due to exponential volume increases.”
