Instant messaging attacks spike in April

Security firm says numbers up more than 100%

Instant messaging attacks leapt 162% in April according to security firm Akonix. The company tracked 21 new malicious code attacks over the month.

The jump accompanies a boom in take-up of enterprise unified communications systems (UC) over the past few months, a fact that is unlikely to be a mere coincidence, Akonix says.

UC systems are designed to bring together all a company's communications systems onto a common internet protocol (IP) infrastructure, and often include an IM service.

Analysts Butler Group reassured enterprises in a report earlier this week that UC does not open up any new means of attack, but Akonix said the recent spike in IM attacks indicates just the reverse.

"Enterprises need to realise that implementing new communication and collaboration tools increases the risk of attack as each new application becomes a new vector for infection," says Akonix vice president of marketing Don Montgomery.
