Phishing and other threats aim to steal personal information like account numbers, social security numbers, and passwords. Attackers use tactics that appeal to human nature like fear, sympathy, and greed to trick people. Traditional phishing emails may contain malicious attachments or links that can download malware and give attackers access. No computer is completely safe, as Macs, phones, and even trusted websites can potentially be used for fraud and exploits. The best defenses are to verify any suspicious requests through other means, follow intuition, and avoid clicking links or entering information in emails.
An ethical hacker breaks into the security system of a website or computer on the instructions of his employer only to strengthen its security and prevent from hackers
Vulnerabilities
The larger and more complex information systems are, the greater the possibility of error in logic and loopholes in algorithm.
These are weak points that could enable hackers to breach a system and compromise the integrity of information stored. Programmers themselves who are not yet adept in writing software code can unknowingly misuse the code and lead to a vulnerability.
A classic example of vulnerabilities that can be exploited is a weak password or its repeated use on various services or software. There are also websites containing malware that installs automatically once visited. Even legitimate software could be a venue for an exploit due to unknown errors (bugs) generated by the program. The end-user or the human element in information systems is arguably the weakest point that hackers easily utilize.
0-day exploits
0-hour or 0-day attack is the exploitation by outside parties of a security hole in a computer program which is unknown from its developers. The term comes from the premise that the attack unfolds on the “day 0, meaning no awareness as of yet from the developers so there is no opportunity and time to issue a fix for the threat. Zero-day exploits are usually shared among hackers even before the developer knew.
Programmers could use the vulnerabilities via several avenues: on web browsers and email. Web browsers allow for a wider target. Meanwhile, using email, hackers can send a message that includes an executable file on the attachments, set to run once downloaded.
Such 0-day threats are in the time frame where a security hole is exploited up to the time that the program developers issued a patch for it.
Supporting the global efforts in strengthening the safety, security and resilience of Cyberspace, the Commonwealth Cybersecurity Forum 2013, organised by the Commonwealth Telecommunications Organisation. The ceremonial opening examined how Cyberspace could be governed and utilised in a manner to foster freedom and entrepreneurship, while protecting individuals, property and the state, leading to socio-economic development. Speakers of this session, Mr Mario Maniewicz, Chief, Department of Infrastructure, Enabling Environment and E-Applications, ITU; Mr David Pollington, Director, International Security Relations, Microsoft; Mr Alexander Seger, Secretary, Cybercrime Convention Committee, Council of Europe; Mr Nigel Hickson, Vice President, Europe, ICANN and Mr Pierre Dandjinou, Vice President, Africa, ICANN, added their perspectives on various approaches to Cybergovernance, with general agreement on the role Cyberspace could play to facilitate development equitably and fairly across the world.
Hosted by the Ministry of Posts and Telecommunications of Cameroon together with the Telecommunications Regulatory Board of Cameroon and backed by partners and industry supporters including ICANN, Council of Europe, Microsoft, MTN Cameroon, AFRINIC and Internet Watch Foundation, the Commonwealth Cybersecurity Forum 2013 seeks to broaden stakeholder dialogue to facilitate practical action in Cybergovernance and Cybersecurity, some of which will be reflected in the CTO’s own work programmes under its Cybersecurity agenda.

Smartphone Ownage: The state of mobile botnets and rootkitsJimmy Shah
Symbian Botnet? Mobile Linux Rootkits? iPhone Botnets? Millions of phones at risk? The press coverage on smart phone threats is at times somewhat accurate, distant, and occasionally (if unintentionally) misleading. They tend to raise questions such as: How close to PC levels (100,000+ to millions of nodes) have mobile botnets reached? Have mobile rootkits reached the complexity of those on the PC?
This talk covered the state of rootkits and botnets on smart phones from the perspective of anti-malware researchers, including demystification of the threat from mobile rootkits and mobile botnets, the differences (if any) between mobile rootkits and mobile botnets vs. their PC counterparts, and a look at how samples seen in the wild and researcher PoCs function.
This presentation gives an overview of various security issues in mobile phones having different operating systems. Ways to avoid spamming and malware in our mobile phones are also presented.
This slide is a highlevel overview of Cybersecurity which talks about your attacker, malware and how to protect your Information system or Enterprise by using effective security and policy controls.

Your mobile device can become your biggest liability if it falls into the wrong hands. In this presentation, we help you understand:
a. Importance of securing your mobile device
b. Identifying the various types of threats to your mobile device security
c. How to secure your mobile device against such threats
d. How Quick Heal helps keep your mobile device secure
Computer security is the process of preventing and detecting unauthorized use of our computer. Prevention measures help us to stop unauthorized users from accessing any part of your computer system. Detection helps us to determine whether or not someone attempted to break into the system, if they were successful, and what they may have done.
Type of Security Threats and its Preventionijsrd.com
Security is a branch of computer technology known as information security as applied to computers and networks. The objective of online security includes protection of information and property from theft, corruption, or threats attack, while allowing the information and property to remain accessible and productive to its intended users. The term online system security means the collective processes and mechanisms by which sensitive and valuable information and services are protected from publication, tampering or collapse by unauthorized activities or untrustworthy individuals and unplanned events respectively. The basic aim of this article is to Prevention against unauthorized security Attack and Threats.

Heavy Chef Session - Justin Stanford's presentation on Online SecurityHeavy Chef
Last year we saw an alarming rise in hacking attempts on well known blogs, websites and forums across the interwebs. It’s a scary thing being in our industry when you realise that your hard work can be accessed by some Taiwanese dude sitting in a basement in Taipei.
With this in mind, we invited Justin Stanford to talk to us about security in this week’s Heavy Chef Session.
2. Phishing (and
other threats)
Detect and deal with email traps and other
potential security problems by using good
judgement and knowledge. Technology can
and will fail, it is up to us humans to be last
line of defense
3. What are their general
goals?
Money
Information
Access
Control
?
4. What are their specific goals?
Account Numbers/Names
Social Security Numbers
PINs/Passwords
Logon Credentials
Secure Access
Entity Impersonation
5. What are their tactics?
Existing trust
Building Trust
Fear
Sympathy
Greed
Appeals to human nature
6. Traditional Phishing is
combined with other exploits
Phishing emails may contain
malicious software in
attachments
Or links to sites with downloads
Attackers with your access
become you
7. Macs are NOT safe from
malware
At one time Macs were safer
that windows PCs, but this was
due to marketshare not security
features
As Macs get more use, so
follows the attacks
Anti-virus is based on known
threats - does not detect
potential threats
8. Phones are NOT safe from
malware
Phones were only safe because
they were “dumb”
Phones did not have storage
space, program running space,
or the ability to conduct
transactions
Phones and all mobile devices
(endpoints) are now bridges for
attackers into networks
9. Even trusted sites can be
dangerous
Attackers can and will use
trusted platforms to gain
automatic trust
LinkedIn, Amazon, Facebook,
etc. are routinely used for fraud
Cross-site scripting - third party
advertising with exploits
People you know and trust
could be compromised
themselves
10. What to do?
Verify, verify, verify
Follow your gut
If suspicious, call before
responding
Go directly to websites, not
links in emails and never use
forms inside of emails
Ask…
