48 percent of SMBs worldwide are infected every year; one third of these infections are caused by worms that spread on USB devices

PandaLabs, Panda Security’s antimalware laboratory, has discovered that in 2010, 25 percent of new worms have been specifically designed to spread through USB storage devices connected to computers. These types of threats can copy themselves to any device capable of storing information such as cell phones, external hard drives, DVDs, flash memories and MP3/4 players.

The data from Panda Security’s Second International SMB Security Barometer suggests that this distribution technique is highly effective. With survey responses from more than 10,470 companies across 20 countries, it was revealed that approximately 48 percent of SMBs (with up to 1,000 computers) admit to having been infected by some type of malware over the last year. As further proof, 27 percent confirmed that the source of the infection was a USB device connected to a computer.

According to Luis Corrons, Technical Director of PandaLabs, “At present, much of the malware in circulation has been designed to distribute through these devices. Not only does it copy itself to these gadgets, but it also runs automatically when a USB device is connected to a computer, infecting the system practically transparently to the user. This has been the case with many infections we have seen this year, such as the distribution of the Mariposa and Vodafone botnets.”

So far, these types of infections are still outnumbered by those that spread via email, but it is a growing trend. “There are now so many devices on the market that can be connected via USB to a computer: digital cameras, cell phones, MP3 or MP4 players,” adds Corrons. “This is clearly very convenient for users, but since all these devices have memory cards or internal memory, it is feasible that your cell phone could be carrying a virus without your knowledge.” Read the rest of this entry »

Advanced Analogic Technologies introduced the AAT3698, a single input 1.6A linear charger with 28V input protection and 50mA low dropout (LDO) to manage the charging, sequencing and protection of Lithium (Li)-Ion and Lithium Polymer-powered portable devices. Targeting portable electronic devices including cellular phones, GPS navigation systems, portable media players and general hand-held consumer devices, the AAT3698 incorporates key safety features that adjust for excessive temperature or voltage, up to 28V, to avoid over-charging or other damage to the battery during charging.

“Lithium-Ion and Lithium-Polymer batteries are nearly synonymous with today’s portable electronic devices,” said Roger Smullen, product marketing manager at AnalogicTech. “A device’s ability to maximize its battery life and charging speed, while minimizing power loss is a critical consideration to its acceptance in the consumer marketplace. The AAT3698 is able to deliver these performance characteristics through USB connectivity or an AC adapter, giving designers even more options to enable broad adoption.”

Part of AnalogicTech’s Battery Manager(TM) Total Power Management IC(TM) (TPMIC(TM)) product family, the AAT3698 is a linear battery charger IC developed for single-cell Lithium (Li)-Ion and Li-Polymer batteries. Able to manage input voltage of up to 7V the IC integrates many features to increase design flexibility and facilitate design-in. Among these features are a 5V/50mA LDO that can provide additional power to an external device such as a radio in a wireless-communication product. This regulator is enabled at all times regardless of the status of the charger and is protected by an over-voltage protection (OVP) switch.

The AAT3698 is a small standalone charger solution that requires only 2 resistors and 4 small capacitors to operate and comes in a small, lead-free 14-pin 4 mm x 4 mm thin quad flat no-lead (TQFN) package. The AAT3698 precisely regulates battery voltage for Li-Ion/Polymer battery cells through a low RDS (ON) switch after it has reached 4.2V. The charging current can be set by an external resistor up to 1.6A.

Besides the IC’s built-in OVP circuit that helps prevent damage to the battery and the charging circuitry, other fault conditions are monitored in real time. In case of an over-current, battery over-voltage, short circuit, or over-temperature failure, the device will automatically shut down, thereby protecting the charging device, control system, and the battery under charge. A status monitoring output pin (STAT) is provided to indicate charging activity. This open drain output pin can be used to drive an external LED as a charging indicator. When the battery voltage has reached the constant voltage level, the AAT3698 has two charge termination and recharge modes— one controlled by the charger (AAT3698-1) and one where charge termination and recharge is managed by the host (AAT3698-2).
