As agencies report a massive surge in spear phishing against executives,looks at the different types of phishing and gives tips for avoiding an attack.
According to the 2018 Verizon Data Breach Report, phishing and pretexting are the two favorite tactics employed in social engineering attacks, used in 98% and 93% of data breaches respectively. And last year, the IRS noted a 400% surge in spear phishing against CEOs.
What is Spear Phishing?
Spear phishing is a targeted attack where an attacker creates a fake narrative or impersonates a trusted person, in order steal credentials or information that they can then use to infiltrate your networks. It’s often an email to a targeted individual or group that appears to come from a trusted or known source.
Spear Phishing vs. Phishing
Spear phishing is a subset of phishing attacks. The end goals are the same: steal information to infiltrate your network and either steal data or plant malware, however the tactics employed by the two are different.
Phishing attacks cast a wide net: phishers are throwing hunks of bread into a lake, and they don’t care what kind of fish they catch – as long as you take the bait, they can get into the network. They’re not personalized attacks: they’re typically distributed to a wide group of people at a time, using something that looks vaguely legitimate in hopes that enough people will click on their link so that they can get more information or install malware.
Spear Phishing, on the other hand, targets a specific individual or group. They lure their victims with information that makes it seem like they’re a trusted or familiar source, with as much personal information as possible to make their approach look legitimate.
Spear Phishing Examples
The Russian cyber espionage group Fancy Bear allegedly committed one of the more famous spear phishing campaigns: using spear phishing techniques to infiltrate the Democratic National Convention to steal emails. They first obtained an updated contact list and then targeted high-level party officials, which lead them to Podesta’s Gmail account. They stole 50,000 emails in one day, and the rest is recent history.
