Cyberattacks are on the rise. The growing number of internet-connected devices and the value of business data means cybercriminals have more to gain than ever from breaking into a company’s network. It’s not uncommon for hackers to target operations of all sizes — meaning that any company holding onto important information needs defenses that will keep that data secure. These seven strategies are some of the most important cybersecurity tactics for a business to use.

The U.S. government aims to tackle cybercrime, in particular attacks targeting critical infrastructure. For this purpose, the U.S. State Department has announced a reward of up to $10 million to anyone who offers valid information about any potential cyberattacks on critical infrastructure supported by foreign states.

AT&T Alien Labs has recently discovered a cluster of Linux ELF executables that have low or zero anti-virus detections in VirusTotal, though our internal threat analysis systems have flagged them as malicious. Upon inspection of the samples, Alien Labs has identified them as modifications of the open-source PRISM backdoor used by multiple threat actors in various campaigns.

One of the most worrisome trends in cybersecurity today is the skyrocketing incidence of supply chain attacks, such as the ones that hit SolarWinds last year and Kaseya more recently. Because they focus on compromising software development and delivery, supply chain attacks have forced developers and DevOps teams to scramble for solutions. Unfortunately, supply chain attacks are particularly challenging to prevent, detect and remediate, and, because of their stealthy nature, are often devastating.

In a world of automation, computers and the data on them have become the backbone of many organizations. But data is a double-edged sword. It can be leveraged by organizations to improve operations, but in the wrong hands, it can be a deadly weapon for hackers. So how do organizations ensure their data is safe?

U.S. President Joe Biden is under pressure to take a stand against a relentless pace of cybersecurity attacks. Russian-speaking hackers have claimed accountability for a recent ransomware assault on IT management software provider Kaseya VSA. The group of Russian threat actors also referred to as the Revil Group, launched a bombshell supply-chain hit during the weekend of July 4th, 2021 against Kaseya VSA and multiple managed service providers.

No discussion on ICS attacks could be complete without talking about what some would call, ‘the elephant in the room.’ Critical infrastructure has always been a target for warfare, and modern ICS are no exception. Several high-profile ICS disruptions have in fact been attributed to malicious hackers working at the behest of a military or intelligence agency.

The term DDoS attack refers to a malicious actor or group of actors intentionally trying to overwhelm a victim’s computer network with traffic. The large influx of network traffic being directed at the target can cause serious issues for legitimate traffic, such as regular users who need to access websites, data or services. Everyone from gamer sites to large enterprises fears the threat of distributed denial of service attacks.

Healthcare providers collect, process and share citizens’ most highly sensitive personal data – from names, dates of birth and contact details, to medical and financial information. The loss of this data by healthcare organisations can cause significant emotional distress to patients if private medical conditions are disclosed, and also make them more vulnerable to identity theft, fraud and further cyberattacks.

Social engineering is a type of cyber attack that targets people to gain access to buildings, systems, or data. Social engineering attacks exploit human vulnerabilities to get inside a company’s IT system, for instance, and access its valuable information. Social engineering is one of the most common— and successful— forms of cyber attack. Social engineering attacks are constantly evolving, but they generally follow five main approaches.
