Best day hackers strike? Research shows it’s not Monday

Today’s sophisticated hackers concentrate more on the best times to carry out attacks so that they can make the most gains from their victims. Proofpoint recently analyzed the timings of email-based attacks in 2016 and revealed some interesting trends.

Proofpoint’s analysis revealed that hackers understand their victim’s habits and will hit when they can get higher success rates. Just like most of us, Proofpoint researchers found that attackers do not like Mondays. However, the sending of ill-motived emails tends to rise by more than 38% on Thursdays compared to other days in the week. Wednesdays came in second, then Mondays, Tuesdays, and Fridays—in that order. Hackers tend to avoid weekends for sending malicious emails, but that doesn’t imply complete absence of email attacks.

Hackers do sufficient background research to ensure emails arrive in their potential victims’ inboxes when clicking is most likely to occur. As such, the researchers found out that most email-borne attacks are sent at the beginning of a busy business day so that victims’ can easily click during working hours. Although ill-conceived emails can be sent during any day of the week, hackers prefer specific days of the week for specific types of attacks. Keyloggers and backdoors realize the best success rates on Mondays; and, Wednesdays are hot days for banking Trojans.

Point-of-sale malware are sent mainly on Thursdays and Fridays, when threat detection teams are less likely to discover new system intrusions. Ransomware emails are best suited for Tuesdays, Wednesdays, Thursdays, and, uniquely, on weekends. Whereas there is no day off when it comes to protecting systems from external attacks, the Proofpoint report indicates that security teams should be extra cautious during certain days of the week—such as Thursdays—when attacks are likely to intensify.

By carrying out extra surveillance during the high threat days, security teams can discover attacks early enough and lower the potential damage.
