How are software vulnerabilities found

The more software that is produced, the more vulnerabilities will exist, Ellis explained. When it comes to the breakdown of high, medium and low-severity vulnerabilities, Ellis said lower impact issues are easier to find and are generally reported more often, with the opposite being true of high impact issues. Pravin Madhani, CEO of K2 Cyber Security, said the lower numbers of high severity vulnerabilities may be due to better coding practices by developers, explaining that many organizations have adopted a "shift left" in recent years and seek to put more of an emphasis on ensuring security is a higher priority earlier on in the development process.

The overall increase in reported vulnerabilities was due in no small part to the COVID pandemic , which forced almost every organization globally to adopt technology in one way or another, Madhani added. Other cybersecurity experts like Viakoo CEO Bud Broomhead said the report was alarming because of how many exploitable vulnerabilities remain "in the wild" for threat actors to take advantage of. The record number of new vulnerabilities, combined with the slow pace of patching and updating devices to remediate vulnerabilities, means that the risk is higher than ever for organizations to be breached, especially through unpatched IoT devices, Broomhead added.

Vulcan Cyber CEO Yaniv Bar-Dayan said that what concerned him most was the mounting pile of security debt that cybersecurity professionals can't seem to get ahead of. If IT security teams are leaving 's vulnerabilities unaddressed, the real number is cumulative and becoming harder and harder to defend against, Bar-Dayan explained.

As an industry, we are still learning from and cleaning up after that one. And it is unfair to put all the blame on SolarWinds considering how the bad actors used known, old, unaddressed vulnerabilities that should have been mitigated by IT security teams well before the SolarWinds software supply chain hack was ever hatched," Bar-Dayan said.

We need to work together as an industry to better measure, manage and mitigate cyber risk, or we will be crushed by this growing mountain of vulnerability debt. Best cheap vacuum cleaner Affordable and reliable too.

The Log4Shell exploit gives attackers a simple way to execute code on any vulnerable machine. Security teams at companies large and small are scrambling to patch a previously unknown vulnerability called Log4Shell, which has the potential to let hackers compromise millions of devices across the internet.

If exploited, the vulnerability allows remote code execution on vulnerable servers, giving an attacker the ability to import malware that would completely compromise machines. The vulnerability is found in log4j, an open-source logging library used by apps and services across the internet.

Logging is a process where applications keep a running list of activities they have performed which can later be reviewed in case of error. Nearly every network security system runs some kind of logging process, which gives popular libraries like log4j an enormous reach. Marcus Hutchins, a prominent security researcher best known for halting the global WannaCry malware attack , noted online that millions of applications would be affected.

The exploit was first seen on sites hosting Minecraft servers , which discovered that attackers could trigger the vulnerability by posting chat messages. A tweet from security analysis company GreyNoise reported that the company has already detected numerous servers searching the internet for machines vulnerable to the exploit. Reached for comment, Valve spokesperson Doug Lombardi said engineers immediately reviewed its systems, and because of network security rules concerning untrusted code, they do not believe Steam is at risk of exploitation.

Apple did immediately respond to a request for comment. To exploit the vulnerability, an attacker has to cause the application to save a special string of characters in the log.

Since applications routinely log a wide range of events — such as messages sent and received by users, or the details of system errors — the vulnerability is unusually easy to exploit and can be triggered in a variety of ways. It's the starkest warning yet from US officials about the software flaw since news broke late last week that hackers were using it to try to break into organizations' computer networks.

It's also a test of new channels that federal officials have set up for working with industry executives after the widespread hacks exploiting SolarWinds and Microsoft software revealed in the last year. New White House policy gives agencies 24 hours to assess cyberattacks of potential national security concern. Experts told CNN it could take weeks to address the vulnerabilities and that suspected Chinese hackers are already attempting to exploit it.

The vulnerability is in Java-based software known as "Log4j" that large organizations, including some of the world's biggest tech firms, use to log information in their applications. It offers a hacker a relatively easy way to access an organization's computer server.

From there, an attacker could devise other ways to access systems on an organization's network. The Apache Software Foundation, which manages the Log4j software, has released a security fix for organizations to apply. Race against time to address flaw. But attackers had more than a week's head start on exploiting the software flaw before it was publicly disclosed, according to cybersecurity firm Cloudflare. Organizations are now in a race against time to figure out if they have computers running the vulnerable software that were exposed to the internet.

Cybersecurity executives across government and industry are working around the clock on the issue. Ransomware attack hits Virginia Legislature. Chinese-government linked hackers have already begun using the vulnerability, according to Charles Carmakal, senior vice president and chief technology officer for cybersecurity firm Mandiant.

Mandiant declined to elaborate on what organizations the hackers were targeting.
