The 5 cyber-attacks you're most likely to face

The fact is most companies face the same threats and should be doing their utmost to counteract those risks. However at some point you may lose your precious data to a vicious cyber-attack, if you’re ever in this position, contact the experts at DLA for assistance!

Here are the five most common successful cyber-attacks.

Cyber-attack No. 1: Socially engineered Trojans

This is the No. 1 method of attack. Usually, a website will tell users they are infected by viruses and need to run fake antivirus software. Also, they're nearly out of free disk space and need a fake disk defragger. Finally, they must install an otherwise unnecessary program, often a fake Adobe Reader or an equally well-known program. The user executes the malware, clicking past browser warnings that the program could possibly be harmful. Voilà, exploit accomplished!

Cyber-attack No. 2: Unpatched software

Coming in a distant second is software with known, but unpatched exploits. The most common unpatched and exploited programs are Java, Adobe Reader, and Adobe Flash.

The best countermeasure is to stop what you’re doing right now and make sure your patching is perfect!

Cyber-attack No. 3: Phishing attacks

About 70% of emails are spam. Even though there are anti-spam vendors, you will probably receive several spam emails each day, and a least a few of them each week are darned good phishing replicas of legitimate emails.

Cyber-attack No. 4: Network-traveling worms

Computer viruses aren't much of a threat anymore, but their network-traveling worm cousins are. We don't see the massive outbreaks of the past with email attachment worms, but the network-traveling variety is able to hide far better than its email relatives.

Cyber-attack No. 5: Advanced persistent threats

APTs usually gain a foothold using socially engineered Trojans or phishing attacks.

A very popular method is for APT attackers to send a very specific phishing campaign -- known as spearphishing -- to multiple employee email addresses. The phishing email contains a Trojan attachment, which at least one employee is tricked into running. After the initial execution and first computer takeover, APT attackers can compromise an entire enterprise in a matter of hours. It's easy to accomplish, but a royal pain to clean up.
